After more than 200 million years as a unique evolutionary group, persisting in the great
extinction that ended the reign of dinosaurs, many species of turtles are now increasingly …

Fundamental questions in ecology and conservation require reliable data about population
size and structure. For freshwater turtles, such data are often obtained via mark–recapture …

Determining the demographic structure of turtles is important to understanding their
population status and conservation needs. Concern has been raised for the long-term …

More than half of turtle species worldwide are threatened because of habitat loss, invasive
species, environmental pollution, disease, unsustainable use, and global climate change …

Empirical evaluation of estimates of freshwater turtle population level parameters (eg, sex
ratio, abundance, size structure, etc.) or the trapping methodology used to sample these …

Turtles are long-lived and globally declining, but relatively little is known about the natural
history of many turtle species. Even amongst relatively well-studied species, there is a …

Abstract Scope and Method of Study. The purpose of this study was to assess the effects of
commercial harvesting on turtle populations across eastern Oklahoma. I also analyzed …

Although necessary for humans, agriculture can negatively affect populations of other
species through direct and indirect means. This is true even for aquatic turtles, which require …

Following perturbations like commercial harvests, turtles are susceptible to population
declines because of life history characteristics such as long generation times, low …

In 2009, we repeated a freshwater turtle survey first conducted in 1976 in the Lower Rio
Grande Valley (LRGV) of Texas to determine whether the abundance of freshwater turtles in …
