Many invertebrate taxa have been reported attached to the shells of turtles. Freshwater limpets (Planorbidae: Ancylinae) have a widespread distribution in North America that overlaps with many species of freshwater turtles. We have observed 5 cases of Ferrissia californica (Fragile Ancylid) attached to the shells of Glyptemys insculpta (Wood Turtle...

Species inventories and distributional analyses at local resolutions provide essential data on distribution, species richness, diversity, and abundance that can inform resource conservation and management. The country of Belize has 9 native freshwater and terrestrial turtle species including Claudius angustatus (Narrow-Bridged Musk Turtle), Chelyd...

The Peninsula Cooter (Pseudemys peninsularis) and the Florida Red-bellied Cooter (P. nelsoni) are considered common throughout much of their respective ranges. Both species occur in numerous habitats in Florida, USA, including rivers, lakes, ponds, freshwater springs, and spring runs. We sampled Peninsula Cooter and Florida Red-bellied Cooter popul...

Movement patterns of turtles can vary depending on natural and anthropogenic pressures and can correlate with sex, size, food availability, reproduction, territorial behaviour, seasonality, location, and habitat. We analysed the movements of Loggerhead Musk Turtles (Sternotherus minor) based on body size, sex, time between captures, and capture seg...

Abstract. Little is known about many life history traits of the Western Alligator Snapping Turtle, Macrochelys temminckii, including the species’ ecology within urban ecosystems. Our study population inhabits waterways of Houston, Texas, the third-largest city in the United States. We conducted a telemetry study on 19.5 km of the Buffalo Bayou that...

The loggerhead musk turtle (Sternotherus minor) and eastern musk turtle (Sternotherus odoratus) are widespread species considered common throughout much of their respective ranges. Florida populations of S. minor and S. odoratus inhabit a variety of habitats, including freshwater springs and spring runs. We sampled populations of S. minor and S. od...

Understanding how stream fishes respond to changes in habitat availability is complicated by low occurrence rates of many species, which in turn reduces the ability to quantify species–habitat relationships and account for imperfect detection in estimates of species richness. Multispecies occupancy models have been used sparingly in the analysis of...

The Florida softshell turtle, Apalone ferox (Schneider 1783) is considered common and easily visible in many freshwater habitats throughout its range. However, very little population research has been completed on the species due to difficulties associated with capture and long-term marking. We have conducted a mark–recapture study of this species...

At two-week intervals from May through November, we set basking traps and baited hoop nets in a 28-hectare Tennessee lake. In alternate weeks, we made visual counts of aerially basking turtles with a spotting scope. Four species of turtles were trapped and observed in the lake. In all, we captured 119 turtles. All four species were captured in hoop...
