We radiotracked eight, free-living, Red-Bellied Mudsnakes (Farancia abacura) from April to October 2019 in a bottomland hardwood forest wetland in Central Arkansas. Four snakes emerged in April from their overwintering sites in an earthen dam of a 1.

Environmental conditions to which amphibians are exposed can influence embryonic development and physiology and thus alter later life-history traits. We exposed Ambystoma maculatum eggs to oxygen partial pressures (PO2) of 1.6, 3.5, 7.9, 12.4, and 18

Body temperatures (Tb) of eight free-ranging Heterodon platirhinos were measured with radiotelemetry throughout the year. Body temperature ranged from 5–37°C and varied with air temperature and activity. During the active season, Tb of active snak

Smooth Softshell Turtles, Apalone mutica, prefer medium to large rivers with clean sand where they spend substantial amounts of time buried in the bottom sand substrate; however, the habitat requirements of hatchling A. mutica are poorly known. We de

We monitored Spiny Softshell Turtles (Apalone spinifera) using mark-recapture during 1994- 2005 in Gin Creek, Searcy, Arkansas. In 1997-2000 the creek bed and riparian zone were bulldozed in an effort to remove debris and improve water flow. This dis

Posthatching yolk in oviparous vertebrates is thought to supply the hatchling with energy for a period of time after hatching in habitats that might require fasting. To examine strategies of posthatching energy use in Apalone mutica, hatchlings were

Pesticides are widely used by humans to eliminate or reduce populations of unwanted species. These pesticides often cause collateral damage by killing nontarget species and altering biological communities. Our study examined the relative importance o

Global declines in amphibians likely have multiple causes, including widespread pesticide use. Our knowledge of pesticide effects on amphibians is largely limited to short-term (4-d) toxicity tests conducted under highly artificial conditions to dete

Oxygen available to amphibian embryos fluctuates widely and is often very low. We investigated the effects of oxygen partial pressure (1.3–16.9 kPa) on embryonic development and hatching of two salamander (Ambystoma) and two frog (Rana) species. In

SUMMARYThe spotted salamander Ambystoma maculatum breeds in shallow freshwater pools and imbeds its eggs within a common outer jelly matrix that can limit oxygen availability. The eggs are impregnated with the unicellular alga Oophilia amblystomatis,
