What Should You Do if You Find a Turtle On The Road?

    Chances are that you have probably seen a turtle trying to cross the road. But roads are dangerous places! 

   Adult female turtles do something that other turtles do not: travel on land to nest. And, this makes them particularly vulnerable to roads. Normally, many eggs and baby turtles are eaten by predators, but this is offset by their long lifespan. If turtles survive to adulthood, then they are tough enough to live for decades. If they lay eggs for many many years then they are likely to produce enough babies to replace themselves in the population. When roads take those adult females out, then the population may decline (this relates to some of my masters research).

   So you see, when turtles get killed on roads it is clearly a big problem for individual turtles but it also affects the overall population too. 

   People often ask me what they should do if they see a turtle crossing the road and I am always immediately clear about one thing: Always Prioritize Your Own Safety. People have been killed helping turtles cross the road and it's not worth it.

   That said, I'm so excited to once again partner with the brilliant Rosemary Mosco (get her new book!) to illustrate why turtles cross the road and what you can do about it (previously we teamed up on Cottonmouth Myths). 


This collaboration was made possible thanks to a grant awarded to me by The Mindlin Foundation and my time was made possible through my work for The Alongside Wildlife Foundation, my 501(c)(3) conservation non-profit Want to support more work like this?

About My Viral Video of a Hognose Snake Drinking From A Water Bottle ---Guest Post---


    
    The work day began for us at 4:30 AM. We loaded up the field truck with our equipment and were on our way. It’s not always easy getting up before the sun, but it is worth it knowing that you increase your chances of finding some really fantastic snake species by doing so. 

    Tristan and I are field research assistants for herpetologists Dr. Mike Dreslik and Dr. Chris Phillips at the Illinois Natural History Survey. Our task over the last few weeks has been to explore several sand prairies in Illinois and document the species of herpetofauna (reptiles and amphibians) we encounter. Surveys like these are critical because they can pinpoint locations of protected species and allow biologists and land managers to implement the best practices to maintain the habitats of these creatures.

    Just as we arrived at our site, the sun began warming the prairie. We walked slowly across the landscape with our eyes glued to the ground, hoping to encounter a snake. During the summer, many diurnal snakes become active just after sunrise before temperatures become exceedingly hot, so this is a great time to look for them. This particular morning was very warm and the temperature was rising quickly, even at an early hour. Despite the increasing heat, we continued our search, meticulously combing the prairie. 

    After a morning of searching – and multiple previous visits to the site with limited success – our efforts finally paid off. A western hognose snake, Heterodon nasicus, was spotted moving through the sandy vegetation, most likely looking for a meal (these snakes love turtle eggs!). Tristan picked up the snake and she immediately “played dead,” a defense mechanism commonly seen in hognose snakes. Western hognose snakes are state threatened in Illinois and live only in a few scattered places across the state, so encountering one of these snakes in the wild was extremely exciting for us. We brought the snake back to our field truck to collect some valuable data from her: we recorded her length, mass, and sex, and took a scale clip as a tissue sample.

    By the time we finished processing her, the temperature on the sand prairie had risen noticeably. It was a cloudless, windless day as well, which enhanced the heat of the sun. Tristan and I were both in need of a water break. We got our bottles from the truck and sat down with the snake before hiking back to the capture location to release her. With temperatures this intense, the snake would normally be down in an underground burrow by this point in the day, so we thought she may be experiencing slight dehydration. Tristan wondered if she would accept water from us – so we gave it a try! 

    I took the lid off of my water bottle and filled it with water. Tristan held the snake up to the lid and she immediately began to drink from it! She took many gulps of water before it occurred to me that I should record this very cool experience. Even after I stopped filming, the snake continued to drink. We were happy that she accepted water from us and it made us feel good to make up for any inconvenience we may have caused by temporarily removing her from her habitat.

    I enjoy sharing photos and videos from the field on social media (Twitter, Instagram, Facebook) because I believe communication between scientists and the public is crucial for the success of wildlife conservation. I wanted my friends to share our unique experience of watching a wild snake accept and drink water, so I posted a clip to my social media accounts. I NEVER expected the clip to receive as much attention as it has! It is incredibly exciting to see the reaction of the public to my video. Snakes have unfairly earned a bad reputation and usually only receive negative attention in the media.

    Responses to my video have been almost entirely positive! Most people that comment on the video state that they have never seen a snake drink before and that seeing this happen helped ease their fears by allowing them to relate to the animal in this way. Some have stated that they didn’t know wild snakes could be so docile. Others are moved by the fact that humans would act so kindly toward a scaly, misunderstood creature and have thanked us for our actions.

    Snake conservation and education is important to us. We consider ourselves lucky to have the opportunity to study these underappreciated animals. Working with rare and understudied snakes such as the western hognose allows us to collect data that can guide conservation actions for the species. Another snake species that we are studying this season is Kirtland’s snake (Clonophis kirtlandii). This snake is also threatened in Illinois and has declined markedly through its entire range. Because it is a small, secretive snake that lives underground inside crayfish burrows, many people don’t get to see how spectacular it is.


    But, we need the public to recognize these animals and their beauty. We need the public to share their observations with scientists. We need to communicate, educate, and conserve. Public observations may be one of the only ways that populations of rare snakes, like Kirtland’s snake, can be documented on a broad scale. Scientists can’t be everywhere at once. Indeed, we all are the experts in our own backyards, stomping grounds, and fishing spots. We just need to do a better job of sharing it*. 

The future of conservation lies in the hands of everybody, scientists and citizens alike. Sometimes this is as simple as submitting a photo to your local biologist or offering a hognose a drink. When will you take a sip? 


*One way you could share your reptile and amphibian observations with scientists is through HerpMapper, a mobile and online application for reporting your encounters!

On Rediscovering "Extinct" Species: The Lost and Found Project ---Guest Post---

This is a guest post by Dr. Diogo VerĂ­ssimo at the University of Oxford, describing a project recently supported in part by The Alongside Wildlife Foundation.


It’s easy to feel a bit down if you follow environmental news from around the globe. Every day there seems to be a new tragedy, a more recent disaster, a more pressing crisis. This is not without reason. The natural world is under threat and in need of more attention, but perhaps there should also be room for some more inspirational stories?

As a child, I was consumed by the story of the Thylacine or Tasmanian tiger, a predator marsupial found only in the island of Tasmania, in Australia. Although this is no doubt a spectacular animal, being the largest known carnivorous marsupial of modern times. It is different to any other existing animal on earth today, representing a unique branch of our planet’s tree of life. But what mesmerized me about this species was the uncertainty around its extinction. While the mainstream narrative is that the last Tasmanian tiger died in captivity in 1936, there have been dozens of sightings of this species, leading to several expeditions to attempt to rediscover it. What if this amazing creature was still out there? What if this unique animal was after all not lost forever? 

I started reading up on these cases, where a species thought extinct was eventually rediscovered. It seemed that the Tasmanian tiger was not alone, and while it seems increasingly unlikely that it will ever be rediscovered, other species have. Many of these rediscoveries are truly inspirational stories, not only of how some amazing biodiversity “came back from the dead”, but also of the incredible commitment, selflessness and courage of the scientists, park rangers and nature enthusiasts involved. Here was my antidote to the doom and gloom that dominates so much of the environmental news. The Lost & Found project was born.

On Earth Day 2017, at the Earth Optimism Summit in Washington DC, the Lost & Found project was launched, with the goal of telling the most surprising, exciting and serendipitous stories of species rediscoveries. We currently cover 20, soon to be 25 species, from craneflies to turtles and newts to flying squirrels, from five continents. We present our stories in both written format and comics to allow for different audiences to enjoy these rediscoveries.

Thanks to a grant from The Alongside Wild Foundation, we were recently able to make important changes to our website, including the addition of five more species and the possibility to translating the content to other languages. So what’s next? We are currently working on five new stories, this time featuring plants, and are hoping to raise funds to have video animations of each of our stories, opening up our content to even more people.

So if you haven’t heard the story of how David Wingate moved his family to a desert island to save the Bermuda Petrel, how the rediscovery of the Bulmer’s fruit bat almost did not happen due to the appetite of a dog, or how Peter Zahler had to resort to a local collector of squirrel poo to rediscover the Woolly flying squirrel, then I challenge you to pay us a visit and get to know some of these incredible tales.

Announcing the Wildlife Grants Awarded by The Alongside Wildlife Foundation

   Hi all, in 2017 I signed up with Patreon to find more justification for all the time I was spending doing outreach and science communication and also because I lacked job security and I was testing the waters to see what paths forward I could create. Once the donations starting rolling in I created a new non-profit charitable foundation, The Alongside Wildlife Foundation, to formalize this work and so that donations would be tax-deductible. In November I gave notice and quit my job at Auburn University. My plan was to develop the foundation (and donate plasma, rent out rooms, do freelance writing, etc) as the next stage of my life. But, shortly thereafter I was offered an exciting new position at the Georgia Sea Turtle Center (I started in January).

   Importantly, because I finally have job security and life stability I was able to make some big changes with the foundation funds I originally planned to keep for my salary. Since January, all donations have been used to grow The Alongside Wildlife Foundation and help other scientists and science communicators accomplish the mission we all share: science-based solutions for living alongside wildlife.

   One of our major initiatives was a small grants program and thanks to our growing army of small donors we have already awarded about $4,000 this year to wildlife projects everywhere from Arkansas to Nigeria. I wanted to highlight the projects that have received funding so far here (and yes, perhaps entice you to become a recurring donor so we can start doing even more).


Ikponke Nkanta (Tropical Research and Conservation Centre): Primate inventory and conservation in Ikea River Basin, Southern Nigeria.
The goals of this project include ensuring 1) future survival of the threatened/important primate species occurring within Ikpa river basin in southern Nigeria through participatory habitat restoration, protection and management. 2) a reduction in forest land encroachment and over-dependence on forest resources as the major source of livelihood (by facilitating adoption of livelihoods alternatives (bee farming, snail farming, fish farming) among hunters and timber harvesters. 3) community adoption of sustainable timber harvesting and better farming practices that are habitat friendly (agro forestry, organic farming) as these do not support further forest destruction, and finally, 4) establishing buffer zones with indigenous trees around the present shrinking territories to stabilize and ‘bridge-up’ fragmented patches.

Lauren Hennelly (UC-Davis): Assessing the status and distribution of wolves in Pakistan using genetics.
The overall goal of this project is to provide important baseline information and resolve what types of wolves are found in Pakistan to inform conservation decisions with several components, including 1) conducting the first genetic survey of wolves across major regions of Pakistan, 2) providing estimates of genetic diversity and potential gene flow to adjacent wolf populations, and 3) provide a clearer picture of the distribution of the Central Indian and Himalayan wolf lineages and the extent of their range. Funds from The Alongside Wildlife Foundation are going towards the purchase of camera traps to gain more information on the local wolf populations and to document the phenotypic characteristics of the wolves to accompany the genetic data. Lastly, there are very few photographs of wild wolves from many regions of Pakistan – camera trap images can become educational resources for the local communities.

Karl and Diane Roeder (University of Oklahoma and Cameron University): The ants of Oklahoma project.
The core objective of the Ants of Oklahoma Project is to  ighlight the diversity of life that routinely goes unnoticed. To accomplish this goal, this program (1) combines historical records found in museum collections, published manuscripts, and online digital repositories with (2) a citizen science outreach component that involves collecting specimens in backyards using standardized methods. Cumulatively, this project will collate information on ant distributions across Oklahoma, create a database of these distributional records, and publish such information for all to view. Moreover, an outreach component will primarily focus on involving undergraduate students in field observations and identification of ants both throughout the year and during annual BioBlitz events. This multifaceted approach will not only increase awareness of our particular taxon of interest, ants (Hymenoptera: Formicidae), but will also encourage citizens and scientists alike to go outside, enjoy nature, and recognize how wonderfully diverse it truly is.



Diogo VerĂ­ssimo (University of Oxford): Lost and Found.

The storytelling project “Lost and Found” works to bring to life the inspirational stories of those species that were thought extinct for at least a human generation but where subsequently rediscovered. The goal of this project is to change the conversations around conservation, away from doom and gloom, and towards a more positive and balanced message about nature. The project will produce a total of 30 stories of serendipitous species rediscoveries across five continents and all animal and plant groups, both in narrative and comics format. This content is developed by professional science and creative writers and a comics artist and is freely available online. 




Wade Boys (University of Arkansas): Surveys, modeling, and prioritization for rare, endemic dragonflies across the Ozark-Ouachita region.

The goal of this project is to conduct rigorous field surveys for four dragonfly species of concern in the Ozark/Ouachita regions. All four of these species are rare and under-surveyed, with one of them being recently described. Their distributions are presumably limited by local habitat and climate characteristics, however, there’s been a lack of habitat-directed surveys. This study will address the sparse records of occurrence and unknown habitat requirements of these insects by combining distribution modeling with field surveys resulting in increased knowledge of their natural history.



Carla X. Neri Barrios (Soluciones Ambientales Itzeni, A.C., Mexico): A children’s book as a conservation education tool for awareness of the natural history of the lesser long-nosed bat (Leptonycteris yerbabuenae).
The goal of this project is to engage children of ages between 7 to 11 in the natural history of the lesser long-nosed bat (Leptonycteris yerbabuenae) through the production and distribution of a children's book with the aim of increasing awareness and empathy towards this and other bat species.

Zackary Graham (Arkansas State University): Field observations on the aggressive behavior of Ringed Crayfish in Colorado.

Despite the extensive research on crayfish physiology and ecology, their natural behavior is extremely understudied. It is often assumed that the behavior and aggression of all crayfish species are identical. But, it is commonly found that the species that have most successfully invaded other populations are more aggressive than less successful invaders. The goal of this project is to conduct behavioral observations of the Ringed Crayfish (Orcconectes neglectus), which is native to Colorado, Arkansas, and Missouri but has been introduced to several locations throughout North America. Currently, the aggressive nature of these crayfish is unknown, and their agonistic behavior has yet to be characterized. These observations will ultimately be used to understand how and why some crayfish are more successful invaders than others. Further understanding of crayfish natural history and specifically aggressive behavior are key to make informed conservation efforts.

Adam Mitchell (University of Delaware): Determining impacts of plant invasion on native arthropod diversity in the Mid-Atlantic.
The goal of this project is to quantify shifts in community structure for arthropods that are impacted by invasive plants in the Mid-Atlantic region. Specifically, it will 1) determine changes in the richness and abundance of arthropod functional groups (herbivores, detritivores, pollinators, and predators) following plant invasion and 2) investigate patterns of change in arthropod community structure in multiple invasive plants to identify which invasive plant (or plants) present the greatest threat to native arthropod diversity in the landscape. 

Erin Spencer (UNC-Chapel Hill): One fish, true fish: combatting seafood mislabeling in the United States.
Seafood fraud often allows less-desired or illegally-caught species to be marketed as a species popular with consumers.  Although there has been media coverage that seafood mislabeling exists, there are little to no resources to teach consumers how to avoid seafood fraud. The goal of this project is to create a website that contains information and tangible tools consumers can use to make smart, sustainable seafood choices that helps promote a culture that values accurate marketing of seafood. The website will include: 1) fact sheets derived from current mislabeling research, including which vendors types (like grocery stores, sushi restaurants, etc.) are most likely to mislabel, 2) web and PDF photo guides for how to identify common seafood replacements, and 3) blog posts and features of local fishermen and vendors trying to support honest, sustainable seafood.

Is This a Wolf or Coyote? ---Guest Post---



Hi LAW,

Could you please identify as coyote or wolf.   

Thank you very much for your help!  

Mark S.



The identification between wolves and coyotes is often confused. The first thing to consider is their range. Historically, coyotes were restricted to the prairies that are west of the Mississippi River and into Central Mexico. However, due to logging, clear cutting for agriculture, the extirpation of the gray wolf and the rise of white-tailed deer populations in the 1800s, coyotes have expanded their range significantly. By the 1930s, they had dispersed around the Great Lakes and up into the northeastern states. Now they inhabit deserts, grasslands, mountains, forests, and rural and urban environments throughout the United States, Mexico, Central America, Canada and most of Alaska.

Map of Coyote range over time from Hody and Kays (2018)

Wolves currently range throughout Alaska, the Northern Rockies, Pacific Northwest, the Great Lakes region, and Canada. The Mexican gray wolf is a subspecies that inhabits the Apache National Forest in southeastern Arizona in a very small population of roughly 113 individuals.

Appearance

Although at first glance wolves and coyotes can look similar, there are some characteristics that set these two distinct canids apart:

Photo courtesy of Macmanes
Coyotes weigh between 30-50 lbs, stand between 16-24 in. at the shoulder and are about 4 ft. long. Wolves weigh between 55-130 lbs, stand at 26-34 in. at the shoulder and are between 4.5-6 ft. long. Coat colors of coyotes vary from grayish tawny in the North, to a lighter tawny in its southern range. The underside and throat of both canids usually have buff or white coloring. The forelegs, sides of head and muzzle are a rusty shade on coyotes. Coyotes have a dorsal stripe formed by black-tipped guard hairs, as well as a black-tipped tail. The color variations of wolves range from white to black, and every shade of tawny in between with black-tipped guard hairs. Both coyotes and wolves have a black “diamond” marking on their tail up near the base that is where a scent gland is located. Coyotes are identified by their large, pointed ears, and narrow muzzle in comparison to wolves. Wolves have rounded ears and a broad muzzle. Both have long legs designed for endurance.

Northeastern coyotes are described as having more of a German Shepard-like appearance. Coyotes in this region are larger than those found anywhere else. This is attributed to the confirmation that northeastern coyotes share mitochondrial DNA (mtDNA) of eastern wolves. Many in the population also share mtDNA of domestic dog.


The animal in the photos sent in by Mark S, is of a coyote mother and her pups that appear to be about a month old. Breeding takes place between January and early March, and gestation last about two months. Pups are born between April and May into litters that average to around 4-5 pups. Den sites vary from rock ledges, hollow logs, and brush-covered slopes to depressions above the ground. Wolves have the same breeding period, gestation length, average litter size, and have similar den sites.

Snake Identification Challenge of the Week - Identify These Snakes!

Greetings Dr., could you help ID the snake in photos attached?  I have combed many internet sites to no avail.  Found it entering my garage in central Oklahoma.  Since it does not match any Okla types, I'm thinking it might have been an escaped pet.
Thank you,
J. P.
Oklahoma




Hi Doc,

I ran across this little guy in Greenville, SC today. It's near a clubhouse in a community so the maintenance supervisor requested an ID. Looking at pictures online for comparison, I think it's an anerythristic corn snake. Do you concur?

Thanks!

Hi Doc,

A friend came upon this on a waterfall hike today. Can you tell what it is?

What Are These Snakes?
-----

Snake Identification Post Ground Rules

-Guesses are welcome and encouraged. Don't worry if you're not an expert, wrong guesses allow us to talk about how to distinguish between the various species and that's why I run these posts.

-If you can't explain why you think a snake is a particular species, go ahead and just say what you think it is. But otherwise please do let us all know how you identified the animal. If you're wrong, we can explain why. If you're right, this helps everyone learn how to identify snakes, which is the point of these posts.

-This is not a pop quiz, any kind of research is encouraged and I hope you will engage with other commenters to try to figure these snakes out. I will eventually chime in with my thoughts.

-Assume I know what kind of snake is in the picture. I run these posts because they are outreach opportunities. Please don't send me private e-mails with your guesses, include them below.

-Remember, the person that sent me the picture is probably reading your comments. Although it is frustrating to know that many of these snakes have been killed, these people do want to learn more about them. More snake knowledge will lead to fewer snakes being killed. Don't hate, educate.


Enjoy what you read and learn here?
