Effect of Caudal Autotomy on Locomotor Performance of Wall Lizards (Podarcis muralis)
The results suggest that lizards that have been previously subjected to caudal autotomy are able to learn by experience how to compensate for the absence of a tail and, accordingly, traverse an arboreal substrate faster - even after their tail has regenerated and is subsequently autotomized again.

Home Range Ecology of an Introduced Population of the European Wall Lizard Podarcis muralis (Lacertilia; Lacertidae) in Cincinnati, Ohio
Small home range size and high home range overlap suggest that the Cincinnati population may have switched from territorial behavior to a hierarchical dominance system, possibly in response to unique pressures (high lizard densities, high predation pressures and low availability of preferred habitat) in the Cincinnati area.

Homeward orientation mechanisms in three species of turtles (Trionyx spinifer, Chrysemys picta, and Terrapene carolina)
The results of this study demonstrate that C. picta, T. carolina, and T. spinifer possess Type III (true navigation) orientation ability. Expand
Behavioral response of amphibian larvae to acidic water
The highest pH at which tadpoles avoided acidic water varied with species and appeared to be related to the acid sensitivity of the test species. Expand
Smallmouth Bass Nesting Behavior and Nest Site Selection in a Small Ohio Stream
Individual smallmouth bass, Mkropterus dolomieui, were observed in a 500-m stretch of Indian Creek, Ohio, during May and June of 1980 and 1981. Nineteen nests were found in 1980; 8 of which receivedExpand
An ultrastructural examination of the mode of UV-induced toxic action of fluoranthene in the fathead minnow, Pimephales promelas
It is demonstrated that the mode of action of photo-induced fluoranthene toxicity in fish is a disruption of mucosal cell membrane function and integrity, and lethality was a consequence of respiratory stress due to the decreased oxygen diffusion capacity of the gills. Expand
Developmental neurotoxicity following premating maternal exposure to hexachlorobenzene in rats.
It is demonstrated that HCB is a behavioral teratogen, and suggested that human fetuses and suckling infants may be at risk from the neurotoxic effects of HCB, and indicated hyperactivity in HCB-exposed pups. Expand
Exposure to lead induces hypoxia-like responses in bullfrog larvae (Rana catesbeiana).
Activity was significantly decreased in larvae exposed to low oxygen, Pb, or both compared to activity of larvae in high oxygen with no Pb; and Lead-exposed larvae surfaced significantly more often than unexposed larvae even under high-oxygen conditions. Expand
Extraocular perception of polarized light by orienting salamanders
SummarySpatial orientation corresponding to the bearing of thee-vector of linearly polarized light can be demonstrated in sighted and eyeless salamanders (Ambystoma tigrinum) trained under linearlyExpand
