How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
I completed my MS at University of Georgia where I studied gopher tortoise health and population dynamics. Currently, I am a PhD candidate at the University of Florida where I research the effects of invasive pythons on mammals (behavior, pop. dynamics, etc.) and ecosystem function in the Everglades.
Diamondback terrapins ( Malaclemys terrapin ) have experienced declines throughout their range, and accidental mortality in crab pots is a significant conservation concern. To minimize the risk of terrapins entering crab pots, researchers have suggested the use of bycatch reduction devices (BRDs) to reduce the size of crab pot openings and thereby...
Population manipulations such as translocation and head‐starting are increasingly used as recovery tools for chelonians. But evaluating success of individual projects can require decades of monitoring to detect population trends in these long‐lived species. Furthermore, there are often few benchmarks from stable, unmanipulated populations against w...
Gopher tortoises ( Gopherus polyphemus ) are among the most commonly translocated reptiles. Waif tortoises are animals frequently of unknown origin that have been displaced from the wild and often held in human possession for various reasons and durations. Although there are risks associated with any translocation, waif tortoises are generally excl...
Translocation, the intentional movement of animals from one location to another, is a common management practice for the gopher tortoise (Gopherus polyphemus). Although the inadvertent spread of pathogens is a concern with any translocation effort, waif tortoises—individuals that have been collected illegally, injured and rehabilitated or have unkn...
Globalization has led to the transport of commodities and plant and animal stowaways to once isolated islands. In some cases, these non-native stowaways become established and alter the island ecosystems where introduced. The introduction of the Brown Treesnake, Boiga irregularis, to Guam is perhaps the better-documented example of an introduced sn...
The Conservation Action Plan (CAP) offers a comprehensive overview of the Green Salamander (Aneides aeneus) species, encompassing its taxonomy, distribution, and ecology. Designed to support the petition to the U.S. Fish and Wildlife Service for an elevated listing of the Green Salamander under the Endangered Species Act, this report is a pivotal c...
The gopher tortoise (Gopherus polyphemus) is declining throughout its range and is among the most commonly translocated reptile species. While some risk is inherent with any translocation, waif tortoises-animals that were collected illegally or have unknown origins-are generally excluded from translocations due to concerns associated with the healt...
I borrowed folding Sherman traps for a project and have a number that are broken/missing components. I am looking for an easy guide or video to share with my technicians who will be assisting with cleaning and assembly. Any suggestions?
I am using the rptR package to assess the repeatability of personality tests for individuals tested on different days. The only thing included in the model at present is whether or not the individual emerged during that test (emerged=1 or 0) and the ID of the individual as a random effect.
rptrBinary(emerged ~ (1|ID), grname=c("ID"), data=data, link="logit", nboot=1000, npermut=1000)
When I run the model above, I get an output like this:
P = 0.00508 [LRT]
= 0.005 [Permutation]
Original scale approximation:
P = 0.00508 [LRT]
= 0.007 [Permutation]
Because the p-values from the likelihood and permutation tests appear significant but the confidence intervals appear very wide, I am not sure how to best interpret these results. If anyone has any insight or resources beyond the original vignette from the authors, that would be appreciated.
Limited research on reptile diets using this technique--especially snakes. Thoughts on barriers to this or tips for success?
My understanding is that raccoons are still relatively small (~2lbs) when they begin to accompany their mother on foraging excursions. Presumably some larger snake species that feed on similarly sized rabbits could consume juveniles, but I have found no evidence of this in snake diet studies though. Any records I am missing?
