“…This indicated that physiological processes can be affected by pesticides. Within the tolerance range of a species, increasing temperature will increase growth rate (Moore 1939), induce relatively higher levels of abnormalities (Harkey and Semlitsch 1988) and increase hyperactivity (Ferraro 1992). All of these factors potentially exacerbate predation levels, for example larger tadpoles may be more vulnerable to predation (e.g.. Crump and Viara 1991;Kaplan 1992).…”

“…The effect of temperature on the survival of tadpoles and eggs has been known for many years (Moore 1939) and general principles are well established (Duellman and Trueb 1986). It is known that high temperatures frequently induce abnormalities in developing frogs (Harkey and Semlitsch 1988).…”

“…Temperature as a factor in reducing numbers and diversity of frogs has not been investigated, although studies on lethal temperatures and temperature resistance have been undertaken (e.g., Moore 1939;Heatwole et al 1968). Intraspecific variation in the temperature tolerance is generally evident in frogs, with individuals being able to survive the temperature extremes to which they are most often exposed (Brown 1969;Brattstrom 1963;Heatwole et al 1968;Snyder and Weathers 1975).…”

This paper reviews the factors involved in the decline, both inter-and intra-specific, of Australian frogs from both disturbed and apparently pristine habitats. Despite a lacl< of published accounts and an absence of long term population studies, a variety of causes were identified. Habitat changes, owing to human influences, are lowering frog numbers and species diversity. Other factors involved include heavy metals, pesticides, salinity, temperature, disease, competition from introduced species and human collection. The complex interactions and synergistic effects of these factors on frogs have yet to be fully elucidated. However, since frogs are sensitive to environmental influences at all stages of their life cycle, population studies would provide base line data to identify, at an early stage, the impact of human influence.

Wood frog adaptations to overwintering in Alaska: New limits to freezing tolerance

We investigated the ecological physiology and behavior of free-living wood frogs [Lithobates (Rana) sylvaticus] overwintering in Interior Alaska by tracking animals into natural hibernacula, recording microclimate, and determining frog survival in spring. We measured cryoprotectant (glucose) concentrations and identified the presence of antifreeze glycolipids in tissues from subsamples of naturally freezing frogs. We also recorded the behavior of wood frogs preparing to freeze in artificial hibernacula, and tissue glucose concentrations in captive wood frogs frozen in the laboratory to −2.5°C. Wood frogs in natural hibernacula remained frozen for 193±11 consecutive days and experienced average (October-May) temperatures of −6.3°C and average minimum temperatures of -14.6±2.8°C (range −8.9 to −18.1°C) with 100% survival (N=18). Mean glucose concentrations were 13-fold higher in muscle, 10-fold higher in heart and 3.3-fold higher in liver in naturally freezing compared with laboratory frozen frogs. Antifreeze glycolipid was present in extracts from muscle and internal organs, but not skin, of frozen frogs. Wood frogs in Interior Alaska survive freezing to extreme limits and durations compared with those described in animals collected in southern Canada or the Midwestern United States. We hypothesize that this enhancement of freeze tolerance in Alaskan wood frogs is due to higher cryoprotectant levels that are produced by repeated freezing and thawing cycles experienced under natural conditions during early autumn.

“…(ii) The "labile" view, based largely on recent studies of tropical iguanid lizards (Huey, 1982a), argues that thermal physiology does respond readily to directional selection in some taxa (see also Moore, 1939;Hutchison, 1976;Sopina, 1976;Miller and Packard, 1977;Hirshfield et aI., 1980). In the tropical iguanid genus Anolis, mean activity temperature in nature and preferred body temperatures in laboratory thermal gradients (Ruibal, 1960;Rand, 1964a; Corn, 1971;Clark and Kroll, 1974;Huey and Webster, 1976), the range of activity temperatures (Ruibal and Philibosian, 1970;Huey and Webster, 1975;Lister, 1976;Hertz, 1982), and Critical Thermal Maxima (Hertz, 1979) often differ markedly among closely related species and vary in concert with environmental temperatures.…”

Ectotherms can compensate for geographical and temporal changes in the thermal environment in several ways: by behavioral regulation, by physiological acclimatization, and by genetic differentiation among populations. Most lizards (Bogert, 1949;Huey, 1982a) compensate by using fast-acting behavioral shifts (e.g., changes in time of activity and in basking activity), and many species also show supplementary (and slower) acclimatory responses (Corn, 1971;Spellerberg, 1972;Hertz, 1981). Whether closely related lizards living in thermally distinctive environments also show genetic adaptation in thermal physiology (Hertz et aI., 1979) has frequently been debated-often in the pages of this journal. Two competing views have emerged over the last three decades.(i) The "static" view, based largely on studies of desert lizards (Bogert, 1949; see also Ushakov, 1964;Brown and Feldmeth, 1971;Hutchison, 1976), emphasizes that thermal physiology is evolutionarily conservative and thus relatively insensitive to directional selection. This view is derived from the empirical generalization that aspects of thermal physiology of lizards typically show little differentiation within or among closely related taxa from climatically distinctive habitats. Because these taxa effectively adjust their thermoregulatory behaviors to local environmental conditions, geographic variation in body temperatures during activity-and
