With so many friends and family members spread through the country, I wanted to live stream my talk so they could be here to support me. In fact two of the most important people in my life, my husband and my father, are tucked away in Wisconsin while I was here presenting. The good news is the talk is here for you all to enjoy. This is an ever evolving talk, so if you have more input, please feel free to email me!
I wish I would have made the David Lazcano talk, I happened to come in at the end and he was funny. Emmanuel Van Heygen was the first talk I caught. Speaking on the North-Western Madagascar and the Phelsuma Geckos he gave a quick break down of each species and its distribution range. Any talk that Emmanuel gives is always accompanied by lovely photos he has taken when in the field. Bamboo sounds as if it is the key to proper husbandry of the Phelsuma geckos. There was a lot of breakdown of each species with photos of them in their natural habitat.
A multi-disciplinary approach needs to be used to look at vet med for endangered species. More than treating the illness but treating the situation and environment. The program that they worked with for the Rio Grande River Cooters targeted the area pollution as well as the water pollution oat the TX-Mexico borders. The compared both pristine as well as contaminated river systems for the research and they used the animals from the Devil’s and Peco’s Rivers as their baseline species.
They did sampling, physicals, blood work, to compare with the Rio Grande population. They also assisted on the Cyclura pinguis project on the Virgin Islands. It was a head start program to help reintroduce the species on the wild. The benefits of releasing head-started animals are obvious, but the drawbacks are issues. They tend to imprint on the birth location, they have a harder time finding hide spots, feeding and basking locations. The project head-started, implanted transmitters and then tracked the animals after release.
The post-lunch talks started with Dr. Gary Ferguson on his field work with the Texas Horned lizards. They are secretive, slow moving, and cute. How true that is.
They are opportunistic insectivores however while they will go after anything that moves it appears the ants are what they can only catch/ The common agreements seem to be that they are a longer-lived animal, with the oldest so far tracked at 8 years ago going strong. In Texas they seem to be a species of concern, but their global status is fairly stable.
In Texas, pretty much everyone knows the Horny Toad; they are the mascot of TCU. In captivity, they are very hard to maintain, but it really is possible. The diet seems to be the hardest part of the husbandry. One lizard can eat between 30-100 ants per day. They also have a very large space requirement and for their size they need an exceptionally large cage in comparison. He explained the UV and thermal gradient studies that they did. Sharing a bit of the natural history of their campsite, he went on to describe the techniques. One difference between the sexes is that the males tend to spend more time midday hiding at ground level under the vegetation, but the females, while still staying out of direct sunlight, they tend to climb higher.
Ari R Flagle then spoke on the basking levels of Boelen’s Pythons.
Having survived the Biology of the Rattlesnakes Symposium in Tuscon, we are continuing our road trip. I will be hitting the pavement with Bryan Grieg Fry to make our way to the International Herpetological Symposium in Fort Worth, Texas. We will be making a pit stop along the way, paying a visit to former chat guest Doug Hotle at the Albuquerque Bio Park in Albuquerque, NM.
This year, follow me on kingsnake connect and you will see everything I am doing as it happens.
Are you a regular Twitter user? We have started a hashtag for the event! Post from the show with #IHS to join in on the fun! Not familiar with how hashtags work? No problem! Check out this helpful link for more information.
Safe travels to all on their way to and from the show. If you see me, please stop and say hi!
My original reason for visiting the Albuquerque Bio Park was to see Doug Hotle and his sea snakes, but the prize was the Komodo Dragon. How did I not know there was one there?
After leaving the Chiricahuas early in the morning, Bryan Fry and I headed on our long journey to visit Doug and see his amazing collection. We arrived a bit later than we would have liked, but it worked out in the end as Doug had a slight emergency to deal with in the morning.
After making my first drive in mountains and a very long desolate drive from one side of the state to the other, we arrived at the Bio Park mid-afternoon. Grabbing Doug quickly at the end of the day, we had an amazing tour. Starting with some of the animals in his garter snake program and ending with the sea snakes, it was one of the top venomous collections out there.
The true joy for me came when I turned around in one room and saw the sign on the door. KOMODO. The sheer happiness and excitement that those words put in all of us was epic. But when Doug said we could play, that sent me to insane peaks of ecstasy!
Guiding us in to meet the male, I was very glad I wore shoes that covered my toes. An outgoing man of beautiful shades of turquoise and orange, he slowly took the time to greet each of us. Then one of Doug's assistants made my day offering to allow me to feed him. Snuggling and feeding? Can it get more epic?
Sometimes being the early bird is a good thing, and today was no different. I was up with the sun and stepped outside to get a few shots of the Chiricahua Mountains in the morning light, and behind me came a very well known face planning to do the same thing. While I stayed barefoot on the slab of the lodge, Mark O'Shea walked with a purpose. He wanted to get a clear shot of the fire damage and trotted across the street.
I stood in my jammies taking a few shots and keeping half an eye on Mark as he crossed the street until I saw that well known white shirt drop down. Turning to look, I saw him coming toward me, camera over his shoulder and snake held very securely in both hands. At that point being barefoot really didn't matter; I had to see what he had. It was a Mojave Rattlesnake and the two of us ran up to the lodge and bagged it. Of course this resulted in everyone present being woken up, but hell -- it was a Mojave!
Needless to say, we then started walking a bit more of the grass, Mark, who caught the snake by almost stepping on it in sandals, switched to boots, and I put shoes on and walked the shoulder of the highway. Nothing else was found, but what a way to start a day!
Saturday night, the Biology of the Rattlesnakes Symposium ended with an auction to benefit the Student Grant Program. On Sunday, that was followed up with a wonderful barbecue at the Chiricahua Desert Museum, owned by Bob and Sherry Ashley.
Having watched the museum built from the beginning up, I cannot tell you how excited I was to finally get there. The store itself put me into shopping overload and I couldn't decide what to buy (I got a long sleeved shirt), but the main gallery is an amazing walk down memory lane for the reptile community. Letters from famous herpetologists, artwork, a stamp collection, book collections, kitchy items, pop culture -- amazing, all of it. One of the memories I will hold dear and take home is sharing time hearing about Mark O'Shea's hero and sharing the story of my IHS talk with Mark.
Another memory is meeting one of the more infamous herpers we have ever had grace our site. FR, aka Frank Retes, happened to be there and, amazingly, recognized me. He was not quite what I expected, yet every ounce of what I expected. We had a few long discussions on husbandry and got along like old friends. That is what this community is about, putting aside everything else, sitting down and having a beer together.
Bob and Sherry did a wonderful job and I also want to thank them for their hospitality for the Chiricahua Lodge. Seriously, if you are thinking of somewhere to crash and go herping, you can NOT pass up this lodge.
When talking about coming to Arizona, there was one single animal that was the cream of the crop for me to see in the wild, the all mighty Gila Monster. I love these little tenacious creatures; they remind me of bulldogs with their stocky thick build and big ole smiles.
We headed out in a group caravan after grabbing a quick bite to eat. Hitting yet another location with rocky hills, I didn't fare quite as well as the previous night, taking one amazing tumble and rolling my ankle, spraining it. Unfortunately I sprained it fairly early in the hike, and, well, the Gila were calling. Luckily my girl Linda from the CHS stayed behind and took the slow walk with me.
Our first find was a road kill frog, however we followed that up with a lovely tarantula.
Finding the girl was amazing. Bryan Fry sexed her out as a sub-adult female on look. Smiley stunning girl with that big old grin sillouetted in the moonlight (and, of course, our lamps and flashlights). Tonight we may head out after the banquet for the other goal species, the Sidewinder, but for now, I am a happy girl and can leave Arizona satisfied. BTW, did I mention Chip is a rockstar herper?
After getting up at the crack of dawn to head down to Tucson to attend the Biology of the Rattlesnakes Symposium, the last thing I wanted to do was be awake for 23 hours -- but herping called. I managed to invite myself along with a few guys who were going to look for Crotalus willardi and Crotalus lepidus klauberi, both Holy Grail finds to herpers.
For those who know me, you know I am not the most physically fit. I wasn’t really prepared for the walking we did or the vertical climbs we made on the hillsides. I am also not the most graceful, but I survived a long night hike, climbing dead trees, rocky hills and crossing barbed wire fences. We did a little mild road cruising on our way up and our first find was a fresh hit checkered garter snake. Several DOR garters and gopher snakes lay ahead but our first venomous find was a Mojave rattlesnake. YAY! There really ARE rattlesnakes in Arizona! Heading to an area where Chip, one of our guides, did a lot of his research, the road was pretty quiet. Although I was highly amused when we had to stop the truck to allow a heard of cattle to cross.
My new friend Ron loaned me his headlamp. While very useful, I was annoyed by the fact that it seemed to attract every single bug in the state of Arizona to my face. What was even more frustrating is that they would get underneath my glasses, effectively blinding me while I was trying to watch out for rattlesnakes and watch my footing.
Unfortunately, we may have spent a little too long cruising up to the spot, but we did manage both target species. Crotalus klauberi was first and we found the willardi not to long after. What was really kind of fun was watching Chip, our uber guide, do his research notations. We also came across some bales of marijuana and a rotting cow body. Other than that, the walk was pretty quiet. On the ride home a night snake and a DOR Crotalus atrox were our new finds -- or at least, the last things I remember before I fell asleep. Getting back to the hotel with four hours to sleep before I needed to be up, I am definitely hoping to have another successful night tonight as we head out for Gila Monsters. With Chip as my guide, I think it will rock.
We started off today with a quick continental breakfast at the Marriot and then a short bus ride to the Sonoran Desert Museum. All our talks today for the Biology of the Rattlesnakes Symposium will be here.
We got here early enough -- crack of dawn, actually -- to spend the morning hiking. Bill Love and I took turns taking pictures of each other taking pictures, but my highlight was seeing a Ctenosaur similis male sitting proud and big on a rock. I managed to grab a quick coffee and head to the talks at the end of William B. Hayes talk on niche partitioning on living environments. One of the points from the talk was that niche differences do not appear to result from partitioning. It also seems to show that it is related to pre size. The research primarily compared the living environments of helleri and Southern Pacific in California.
Matt Holding spoke next on the effects of short distance translocation on the Northern Pacific rattlesnakes. All images are Harry Greene approved. One thing we need to look at to deal with human and rattlesnake interactions is the biggest thing is we need to observe the location of translocation; however, we also need to train people to properly handle the animals. Long distance translocation is often extremely bad resulting in a high mortality rate. The downfall with short distance, though, is the animals often will return.
Corticosterone is a hormone that, mobilizes energy stores. Chronic rises in CORT can be very detrimental to the health of the animal. What the study looked at was how they can control and adjust handling to adjust the chronic stressors to reptiles. The study also focused on adult males. They took two different blood samples of both baseline and stress sample. To get the stress blood sample, they took baseline, held the animal in a secure bucket and then drew again. When they compressed the data at the end, when the baseline was taken at both initial and final, the baseline levels were equal however the stress level was greatly increased on the second stress induced test. The testosterone levels, however, did not seem impacted in the initial capture, however in final capture; there was a huge drop of testosterone at the final stress testing.
The conclusion is that rattlesnakes seem to bounce back with short distance relocation. Although there is a difference it doesn’t appear to cause long term health issues.

In China, perhaps they should change it from year of the rabbit to year of the pit viper with the discovery of a third new species this year.
From National Geographic:
The new snake, Protobothrops maolanensis, was an unexpected "surprise gift for us," study leader Jian-Huan Yang said in an email. (See snake pictures.)
Yang and colleagues found the species during a recent survey of forests in Maolan National Nature Reserve in Guizhou, China (see map). At a maximum length of about 2.6 feet (0.7 meter), the new pit viper is the smallest known so far in the country.
Though the grayish brown species easily blends into its habitat, the ground-dwelling species ended up being the most common snake found during the research, noted Yang, of Sun Yat-Sen University in Guangzhou.
Scientists have found two other new pit vipers in China so far in 2011: Sinovipera sichuanensis and Protobothrops maolanensis, he added.
A recent discovery in Saxony of a perfectly petrified tree-dwelling lizard shows that lizards came well before the dinoosaurs. The animal resembles the modern day Green Iguana, but is currently being dated to the Permian period between 300 million and 250 million years ago.
“Most other reptiles lived on the ground,” (Jörg Schneider, professor of palaeontology at Freiberg University) told The Local. “For the first time we really know this animal was specialized for living in trees … They have unusually long and slim fingers and very long tails … It is a completely new form that is unknown.”
The Permian period was marked by the diversification of land vertebrates and appearance of modern trees such as conifers. All of the modern continents were clumped together in the single supercontinent, Pangea.
Mammal ancestors such as the famous fan-backed Dimetrodon flourished but the period ended with a massive extinction 250 million years ago that wiped out about 70 percent of land vertebrates, probably through a combination of climate change, volcanic activity and asteroid strikes.
The petrified forest on the outskirts Chemnitz is remarkably intact because it was buried in fine ash from a nearby volcano eruption. Normally such fossil remains of animals have been washed some distance from where they lived and died and then preserved in lakes and sediments, Schneider said.
The Chemnitz forest, by contrast, has been preserved virtually as it stood 290 million years ago, complete with trees, insects, spiders and snails as well as larger vertebrate animals. The reptiles were found at the foot of the trees from which they fell.
“You could call it the Pompeii of Saxony,” Schneider said. “They are exceptionally well-preserved skeletons because of this very fine ash. We could see every bone, we could see the outline of the skin and beautifully preserved scales. It looks like they just died days ago.”
Despite the lack of external ears, German physicists have found that snakes do in fact hear -- and they hear in stereo!
(T)hey do have complete inner ear systems, including functional cochlea, which are carefully connected to and stimulated by their lower jaw. Resting on the ground, a snake's jaw can detect vibrations as small as an angstrom in amplitude (a motion roughly as large the diameter of a single atom), which act like sound waves to the inner ear.
The physicists performed a geometric study of the anatomy of horned desert vipers as well as the ground waves created by the footfalls of their prey. They showed mathematically that the jaw-to-cochlea system is sensitive to the frequencies of the prey's ground vibrations.
From their analysis, the physicists also found that the snake's notorious ability to unhinge their jaws and swallow their prey whole means that the right and left side of their jaws can receive vibrations independently, and the snakes hear in stereo.
One hundred thirty years is a long time to live, even for a tortoise. This past week the reptile community lost of one their ancient giants: Methuselah, a 130-year-old Galapagos Tortoise, passed away quietly at Reptile Gardens in South Dakota.
Originally named Earl, he was born in 1881 on the Galapagos Islands and joined the Reptile Gardens family in the 1954. I had the pleasure to meet him and his yard mates, Quasi and Tank, last summer on our family trip to the Gardens. Both Tank and Methuselah were exceptionally friendly and they loved to have their long necks scratched. Both also loved dogs; who knew!
From the Reptile Gardens blog post on his passing:
Those of us who worked with the tortoises on a daily basis learned each one’s personality, their habits, preferences, and behaviors. Methuselah, honestly, always had the most personality. He was smart and knew how to get what he wanted. He could be cunning even. Sometimes you could tell he was thinking, as though he was formulating some plan.
Farewell, Methuselah! It was a pleasure to have known you. You were a great ambassador for reptiles everywhere.

The US Fish and Wildlife said this week that the Gila Monster population in Utah is not large enough to warrant endangered status.
The US Fish and Wildlife Service announced Monday that a petition seeking to protect the Utah population of the Gila monster under the Endangered Species Act (ESA) does not contain substantial scientific information to indicate that the petitioned action may be warranted, because the population does not constitute a distinct population segment (DPS) as defined by the ESA. The finding will be published in the Federal Register Tuesday.
Despite the announcement by the USFWS that the species will not receive further consideration for listing under the ESA at this time, the agency will continue to work with its partners to conserve and protect the Gila monster throughout the species’ range, according to the announcement.
[....]
In Utah, it is found only in the southern portion of Washington County, which comprises less than one (.01) percent of the species’ total range.
After dying off in Chambal, Gharials are making a comeback thanks to conservation efforts and reintroductions. And the natives, they couldn't be happier!
Over four years ago, more than 20 gharials were found dead on the Chambal. They seemed to have been poisoned – dying from kidney failure and gout from eating contaminated fish from polluted rivers. "What a horrible death! Poor gharials," sympathises David, as we imagine the sick reptiles suffering.
But a few weeks later we hear some welcome news. The new breeding centre further up river, in the Sheopur district, is proving a success. More than 1,000 baby gharials from more than 40 mothers have hatched in the last month. On the drive back on the bus we talk to a few locals who are very excited about the gharial babies. One young boy tells me thousands have been born; a young woman tells me that there are tens of thousands.
"You have to see the babies diving in the water," urged one boy. The small crocodilians have become local celebrities. Families are now taking picnics on the river at weekends to see the gharials play and feed.
I don't normally like seeing conservation issues played for politics, but I couldn't help but wonder about the implications for our hobby of a deal struck with Republian Senator John Conryn to get new U.S. Fish and Wildlife Service director Daniel Ashe out of nomination limbo.
"With over-regulation growing like weeds in Washington, I will continue to use every opportunity to engage the Obama administration to keep this unprecedented overreach from killing jobs and stifling growth in Texas," Cornyn said in a statement.
"The proposed listing of the sand dune lizard as an endangered species is just the latest federal regulation that threatens not only thousands of jobs in Texas but also our domestic energy resources. I am pleased that the concerns of those most impacted by this premature proposal will be heard, and that Mr. Ashe will ensure that the Fish & Wildlife Service is making this important decision with the relevant data it warrants and on a time frame that ensures proper consideration of the matter."
It remains to be seen if that concern about jobs and growth extends to legislation and regulatory listing that threaten our reptiles.
Called the Tortoise Mafia because of the destruction they leave in their path, Madagascar's tortoise smugglers are becoming more violent as they pull animals from the wild.
"Everybody is eating them and everybody is trafficking them and as soon as people are brought to trial, there are mafia organisations who help to get them out," says the head of Madagascar's Alliance of Conservation Groups, Ndranto Razakamanarina.
Another conservationist, Tsilavo Rafeliarisoa, says two poachers were caught last year in southern Madagascar with 50 tortoises.
This was a small breakthrough in efforts to protect the island's endangered tortoises, which include the Ploughshare, Spider, Radiated and Flat-tailed species.
Often, poachers roam villages in groups of up to 100, picking up thousands of tortoises over several weeks.
They are heavily armed, fending off attempts to stop them.
"When a gang of poachers with guns and machetes come and take tortoises, the villagers are defenceless," Mr Rafeliarisoa says.
He says with food prices rising, more people are eating tortoise meat.

Madagascar is known for its rich biodiversity but this has attracted smugglers interested in everything from its precious rosewood to minerals and tortoises - and the famous lemurs.
An alliance of 27 national conservation groups recently accused the government of being complicit in the illegal trade, as it had not cracked down on the "looting and plunder" of natural resources.
A WWF report on Madagascar's biodiversity earlier this month said more than 600 new species had been discovered in the "Treasure Island" over the last 10 years, but many were already endangered.
With only a few hundred of the world's most endangered Ploughshare Tortoises left, hundreds of species are crawling towards extinction behind them.
The Leatherback Sea Turtle gained protection recently off the coasts of Washington, Oregon, and California offering them a better chance at survival in nesting habitat.
The endangered leatherback sea turtle enjoyed a huge conservation victory this week. The hulking, jellyfish-eating reptile will be protected in ocean waters off the coasts of California, Oregon and Washington due to a settlement filed by the National Marine Fisheries Service and conservation groups. The current settlement proposes protecting 70,600 square miles of critical habitat, but the government has until November 15, 2011 to make a final rule.
The settlement marks a major turning point in a many-year effort by conservation groups to protect the embattled turtle, which travels some 6,000 miles from the western Pacific to the cool waters along the Western United States each summer and fall to feed on scores of jellyfish. According to the Center for Biological Diversity, “as few as 2,300 adult female western Pacific leatherbacks remain.”
The final 30 sea turtles being treated for complications related to the Deepwater Horizon oil spill were recently released back into the wild.
From the Associated Press:
"It took a little time but they actually all healed up very nicely," said aquarium veterinarian Cara Field.
A federal contractor released the turtles Friday off of Venice, Audubon Nature Institute spokeswoman Sarah Burnette said Wednesday.
Burnette said most were healthy enough for release last year, but the remaining 30 wintered at the institute. Earlier this spring, it was either too cold or seas were too choppy for the release, she said.
The worst injured and sickest was the Kemp's ridley sea turtle with one line of puncture wounds in his shell and another in the flat plastron over his abdomen, indicating that he probably escaped being eaten by a shark, Field said.
....
Field said some were anemic because of the exposure to oil. Others had low calcium, broken flippers and a couple had infected toe-bones.
The Cantor's Softshell Turtle has not been spotted in the wild since 2003, but an American based conservation group is working to change that.
From the Associated Press:
U.S.-based Conservation International said it opened the Mekong Turtle Conservation Center on Wednesday in Kratie province, 100 miles (160 kilometers) northeast of Phnom Penh.
A 40-pound (18-kilogram) female turtle and six babies were released into the conservation pond at a Buddhist pagoda on the Mekong River at the center's launch. The ceremony was attended by six Buddhist monks — who blessed the female turtle by painting scared markings on her body — and more than 100 villagers.
"Our goal is to conserve Cantor's turtle populations in their natural habitat, the Mekong River, through the Mekong Turtle Conservation Center and the community-led nest protection scheme," Conservation International said in a statement.
Days before researcher Luke Yeoman was to open his King Cobra Sanctuary, he lost his life working with the very animals he loved the most.
A protege of Rom Whitaker, Luke was highly respected in the venomous community for his work with King Cobras and his study of their behavior. In a recent article celebrating the opening of his sanctuary, he compared keeping King Cobras to some people keeping fast cars:
"People do say that I am mad but I say it's better than people saying you're bad. I think everything I am doing is good," he said.
Luke loved the species he chose to dedicate his life conserving. Describing his work with them in another article, he said:
My life is about the conservation of the king cobra. Our breeding colony here is a safety net in case the king cobra becomes extinct.
[....]
Writing on his sanctuary's website previously, Mr Yeomans said: 'The King Cobra Sanctuary was born from my lifelong love for this amazing snake species and my concerns that it could eventually disappear from the wild.
'Until mankind changes the way he treats the natural world, a living 'Ark' is required for the survival of many animal species.
It is thought he died of a heart attack caused by a cobra bite.
Every spring for as long as I can remember, my phone rings off the hook with turtle removal requests. My rescue isn't permitted for native wildlife, but people see reptiles and call.
From The Morning Sun:
Typically, the turtles — in Crawford County, most are the common snapping turtle, red-eared slider, map turtle and box turtle — winter in the mud near the bottom of a pond, according to Fort Hays State University's Kansas Herpetofaunal Atlas. Their low oxygen requirement allows their skin to absorb enough oxygen through the water. But their habitat may have changed, so it's off to greener pastures, and mates.
It's also egg-laying season, and the turtles are looking for safe habitats in which to construct their nests. With the exception of snapping turtles, they also could be on the prowl for the juicy droppings of a mulberry tree, Glick said.
"They love those," he said
But roads are a problem, and while a large snapping turtle could throw off a vehicle's alignment, the consequences are, of course, much more dire for the hapless turtles.
Glick said it's OK to move turtles off the road as long as it's safe to stop, but he recommends determining their direction of travel first.
"They may just turn around and go back to the other side," he said.
"It's also possible to move snapping turtles. Glick doesn't recommend moving them, but said that if someone were so inclined as to try, he or she should pick the turtle up by its tale, leaving its underside facing toward the person's body and at a safe distance.

A possible treatment for cancer has been found in the proteins in the skin of the Waxy Monkey Frog.
From Science Daily:
The award-winning research, led by Professor Chris Shaw at Queen's School of Pharmacy, has identified two proteins, or 'peptides', which can be used in a controlled and targeted way to regulate 'angiogenesis' -- the process by which blood vessels grow in the body. The discovery holds the potential to develop new treatments for more than seventy major diseases and conditions that affect more than one billion people worldwide.
The proteins are found in secretions on the skins of the Waxy Monkey Frog and the Giant Firebellied Toad. Scientists capture the frogs and gently extract the secretions, before releasing them back in to the wild. The frogs are not harmed in any way during this process.
Professor Shaw said: "The proteins that we have discovered have the ability to either stimulate or inhibit the growth of blood vessels. By 'switching off' angiogenesis and inhibiting blood vessel growth, a protein from the Waxy Monkey Frog has the potential to kill cancer tumours. Most cancer tumours can only grow to a certain size before they need blood vessels to grow into the tumour to supply it with vital oxygen and nutrients. Stopping the blood vessels from growing will make the tumour less likely to spread and may eventually kill it. This has the potential to transform cancer from a terminal illness into a chronic condition.

"It would be a great shame to have something in nature that is potentially the wonder drug to treat cancer and not aim to do everything in our power to make it work."
Ploughshare Tortoises have been coveted for decades, their ownership often connected with direct smuggling, but The Turtle Conservancy in Ventura, CA has recently acquired eight new additions and hopes to breed them.
But Saturday's VIPs were eight ploughshare tortoises flown in from Hong Kong in padded crates. Among them is a female of breeding age, which Eric Goode and his associates at the nonprofit Turtle Conservancy's Behler Chelonian Center hope to mate with the only male ploughshare tortoise of breeding age in North America.
"That male, which is en route from a zoo in Texas, hasn't seen a female ploughshare tortoise of breeding age in more than 25 years," Goode said as he marveled at the new arrivals in a quarantined pen. "We're hoping for the best. These creatures have seen nothing but bad luck, corruption and greed in captivity."
Some would call that an understatement. With fewer than 300 left in the wilds of Madagascar, the ploughshare tortoise holds the dubious distinction of being the rarest tortoise on Earth. They are heavily targeted by global animal traffickers, and the high-domed creatures fetch tens of thousands of dollars on the Asian black market, conservationists say.
Until recently, attempts to breed the ploughshare tortoise outside of Madagascar failed miserably. In the early 1980s, a male died shortly after zoo workers in Honolulu used an electric device to procure semen from the animal. A female that it was supposed to have mated with had her ovaries removed during a botched operation.

My favorite part of being a reptile owner is educational programs with children. Opening their eyes to the natural world around them helps open up children to a myriad of possibilities for their future. Good to see that in India, that feeling is the same.
After the tour, the kids enjoyed a “Show and Tell” session with the education officers. A baby Caymen croc, a baby Indian Rock Python and a baby Black Pond Turtle were displayed and the children were able to observe at close quarters what they would have missed if they saw them from afar. Their characteristics and parts of their body were explained — they got to see the webbed feet of the turtles and examine it closely and learnt the importance of having it. The sinewy muscles of the baby python was exclaimed over — for they now understood how it could coil and twine around things with such strength and move. They noticed the third eye of the baby croc, which closes under water.
[....]
Getting back to the Croc Bank, after a little rest the kids got down to setting up a fresh water aquarium for the turtles. They checked the water levels and kept little pots and vegetation for the turtles to nibble and hide under. They also put in tiny fish. It was now time for some painting, which actually was to create an artificial butterfly garden. The concept was to paint the flower have a vial of honey inserted in the centre so that butterflies would get attracted to it. Play time in the beach was followed by the finale — where certificates and prizes wee distributed with a special Croc Bank Kit.
It was an unique experience for these kids, an experience which made them understand and appreciate the natural world and also the importance of conserving it with everything they've got.
To open the eye of children, especially where there are so many native dangerous reptiles is a wonderful thing.
It may take decades to realize the full impact the oil spills in the Gulf will have on wildlife, but researchers are increasing monitoring of sea turtles during this important nesting season.
From The Associated Press:
While scientists in several states are studying the effects of the oil spill on loggerhead and other sea turtles, the Kemps ridley have been of particular concern. The Deepwater Horizon explosion on April 20, 2010 happened when they typically would have been in the area. Most of the 456 visibly oiled turtles rescued by the U.S. Fish and Wildlife Service last year were Kemps ridleys.
At the peak of nesting season, their numbers looked good. As of May 24, 155 Kemps ridley nests had been spotted on Texas shores — more than in all of last year and more than had been counted by that day in 2009 and 2008. The same is true for some other sea turtle species, although they have just started to nest so it might be too early to have confidence in those numbers.
And because sea turtles don't reach reproductive age for at least a decade, the full effects of the oil spill might not be known for years.
"There is fear that some of the turtles that took the year off from nesting or after the turtles were done nesting during the 2010 year, that they entered the waters where the oil had been present," said Shaver, explaining that the reptiles often forage off the hard-hit Louisiana, Alabama and Mississippi coasts before or after nesting along the Texas Gulf Coast.
"There is concern that perhaps those turtles have been impacted from the oil and could then have problems with their reproduction," she added.
Southland Museum and Art Gallery tuatara curator Lindsay Hazley started out 27 years ago with two animals. She now has a colony of 80 captive bred Tuataras with no where to go.
From Otago Daily Times:
The museum's tuatara surplus is the result of Mr Hazley overcoming many captive-breeding problems and he is getting 20-30 fertile eggs each year.
"With the new acrylic roof I got from Germany that let's all the UV (ultra-violet light) through, I'm getting a 90% survival rate rather than a 90% failure.
"I'm sending eggs to Victoria University from now on because I'm saturated."
Mr Hazley would like to liberate some of his animals on a tiny pest-free island in Foveaux Strait.
"It would be just [big] enough to put a few animals on to see how they are going to do."
Mr Hazley said he had been talking to interested parties about the possibility for 20 years but there had been little progress.
He believed it was not the museum's job to make the project happen.
"It's more of a Doc or iwi thing. Somebody else needs to drive it. I can breed the animals for it but no-one's out there wanting to drive it."
This is an amazing chance at recovery for a species that needs the help badly. To read the full article, click here.
Those who have the chance to watch an Arribada, the mass laying of eggs by numerous female sea turtles, describe it as one of the most amazing experiences anyone could have. But as the turtles become more endangered, that sight is getting hard to find.
From The Hindu, one person's experience:
She was sweet 17, profoundly pregnant; and yet floated effortlessly, adrift in the warm waters off the east coast of India. The Olive Ridley sea turtle was waiting for darkness to envelope her. She was pregnant for the first time and would breed many more times in her life span of 100 years. Stealth was not her intention as she waited 700 yards from the sandy beach at the mouth of the Rushikulya in Orissa. A few yards away, another female turtle joined her, then a third, followed by a dozen, then hundreds and thousands. They gathered as if for a colossal hen party, instinctively following an uncanny ritual that happens in the dead of the night.
All the expectant mother turtles slowly crawl towards the virgin beach. “Look, there comes the first fat lady,” said turtle researcher Sajan John, holding a tiny torch, as I peered into the darkness. I was witness to an Arribada, which means “Arrival” in Spanish. Arribada is the astounding nesting inclination of the Olive Ridley turtle. Large groups of turtles gather off the seashore and, in a short span of a few nights, they invade the beaches in regular intervals to lay eggs in collective clutches. The nesting density is so high that previously laid eggs are unwittingly dug up by other turtles to lay their own eggs! Each clutch has at least 70-100 ping-pong sized white eggs stacked in a tubular pit excavated in the soft sand.
