“…An average total home range length of 327 m is similar to mean home range lengths of 302 and 320 m for two populations of Spotted Turtles in Massachusetts (Milam and Melvin 2001). Maximum total range length in the current study was only 375 m, whereas it was over 1000 m elsewhere in Ontario (Haxton 1998) and in Massachusetts (Milam and Melvin 2001).…”

“…Maximum total range length in the current study was only 375 m, whereas it was over 1000 m elsewhere in Ontario (Haxton 1998) and in Massachusetts (Milam and Melvin 2001). The difference in movements is likely explained by differences in habitat.…”

“…The number of growth lines were counted (when possible) on the left humeral or pectoral scute of the plastron. Unmarked turtles were notched using the system used by Chippindale (Cagle 1939 Mark-recapture and radio telemetry data were collected from 1999-2001 on a population of Spotted Turtles, Clemmys guttata, near their northern limit in Ontario, Canada, and compared with a similar study conducted from 1983-1986-2001 Spotted Turtles were caught, 27 of which were adults. Females outnumbered males 3.5:1.…”

Mark-recapture and radio telemetry data were collected from 1999-2001 on a population of Spotted Turtles, Clemmys guttata, near their northern limit in Ontario, Canada, and compared with a similar study conducted from 1983-1986. In 1999-2001, 32 Spotted Turtles were caught, 27 of which were adults. Females outnumbered males 3.5:1. The carapace length (CL) of adult males (108.5 ± 5.7 mm) and adult females (106.4 ± 6.0 mm) did not differ significantly. A minimum of 22% of juveniles and 40% of adults marked in 1983-1984 were still alive in 1999-2001. Adult population size was estimated to be 45 (95% confidence interval: 34-78). The average size of individual adults marked in 1983 (105.6 + 6.0 mm CL) and recaptured during 1999-2001 (106.3 + 5.9 mm CL) did not differ significantly. There was also no signficant difference in the number of growth lines on adults caught in 1983 (12.9 ± 2.0) and 1999 (14.0 ± 2.3). Based on the number of growth lines in 1983, these turtles averaged a minimum of 28.9 years in 1999, but actual ages are likely greater. Summer range length averaged 233 m (range: 200-275 m), while total range length averaged 327 m (range: 275-375 m).

“…Terrestrial displacements were already reported for other freshwater turtles, such as the chelid Chelodina longicollis (Roe and Georges 2008;Rees et al 2009), and the emydids Trachemys scripta (Gibbons et al 1990), Emydoidea blandingii (Ross and Anderson 1990), and Clemmys guttata (Haxton and Berrill 2001). Presumably, most freshwater turtles have the skill to migrate across land, and effectively do it when resources become meager in their original aquatic habitats (Kramer 1995;Milan and Melvin 2001). Due to this ability, and also considering the confluence of at least three distinct ecosystems and river basins in the state of Mato Grosso, representatives of Chelidae probably have even wider ranges than presently indicated by available data.…”

Distribution patterns of most of the 20 Neotropical freshwater turtles belonging to the family Chelidae are usually based on few locality records. We here report on vouchered records of three species of the chelid genus Mesoclemmys in the Brazilian state of Mato Grosso. Presence of M. vanderhaegei is confirmed for the Amazon River Basin, and M. gibba and M. raniceps are recorded in Mato Grosso for the first time.

“…Across North America, considerable research has been conducted on vertebrates associated with isolated wetlands that dry periodically, including the vernal pools of California (King et al 1996;Riefner and Pryor 1996;Zedler 2003), the Prairie Pothole Region (Austin 2002), the playas of the southern Great Plains (Haukos and Smith 2003), and Carolina bays of the southeastern United States (Pechmann et al 1989;Snodgrass 2000;Sharitz 2003). Within the past decade, wetland ecologists in the northeastern United States have focused their attention on the wildlife associated with seasonal forest pools (Gibbs 1993;Windmiller 1996;Brooks and Doyle 2001;Milam and Melvin 2001).…”

A review of vertebrate community composition in seasonal forest pools of the northeastern United States

Seasonally-flooded wetlands occur throughout the world and provide important foraging, resting, and breeding habitat for a broad array of organisms. This review summarizes our current understanding of vertebrate community composition at seasonal forest pools in the northeastern United States. These wetlands typically have hydroperiods that range from temporarily flooded to intermittently exposed, which reduces densities of many potential predators (e.g., fish). Current research has shown that pool hydroperiod, canopy closure, vegetation structure within pools, presence of potential predators, and landscape structure surrounding pools are the key factors determining vertebrate diversity at seasonal forest pools. Of 25 species of amphibians in the region, frogs (10 of 12 species) are more likely to breed in seasonal forest pools than salamanders (6 of 13 species). Seven of 10 amphibian species that breed in seasonal forest pools are state-listed as threatened or endangered. Among 27 species of reptiles, 3 of 15 species of snakes, and 6 of 12 species of turtles utilize seasonal pools during at least one stage of their annual cycle. Seasonal forest pools are important foraging and basking habitat for three species of turtles listed as threatened or endangered. Compared to other vertebrate taxa, most species of mammals are habitat generalists, with 50 of 63 mammal species potentially foraging at seasonal pools during part of their annual cycle. Chiroptera (bats; all 9 species) are believed to actively forage at seasonal pools and some Insectivora, particularly Sorex palustris Richardson and S. fumeus (Miller) and Condylura cristata (L.), are detected regularly at seasonal pools. Breeding birds are less likely to utilize seasonal pools than other vertebrate taxa, although 92 of 233 species might forage or breed near seasonal pools. Several species of Anatidae, Rallidae, and some Passeriformes use seasonally flooded pools. All vertebrates that use seasonal forest pools use other habitats during some stage in their life cycle; thus gaining a clear understanding of their habitat requirements is critical to their long-term persistence.
