Comparative Biochemistry and Physiology Part A: Physiology, 1981 1. 1. Rates of evaporative water loss were measured under controlled environmental conditions in Scaphiopus holbrooki either paralyzed with tubocurarine chloride or restrained physically. 2. 2. Rates of water loss and body temperatures did not differ significantly between paralyzed and restrained animals. 3. 3.

Late Pleistocene and Early Holocene Vertebrates and Paleoenvironments on the Southern High Plains, U.S.A. [PDF]
, 1986 Only a few vertebrate faunas are known for the Southern High Plains from the late Pleistocene and early Holocene. This review focuses on vertebrate local faunas from two major localities on opposite sides of the region but in the same drainage system ...

Host sexual dimorphism and parasite adaptation [PDF]
, 2012 In species with separate sexes, parasite prevalence and disease expression is often different between males and females. This effect has mainly been attributed to sex differences in host traits, such as immune response.

LIFE HISTORY SWITCH POINT PLASTICY IN RESPONSE TO POND DRYING ALYERS METAMORPH ALLOMETRY AND JUMPING PERFORMANCE [PDF]
, 2012 Animals with complex life cycles can cope with environmental uncertainty by altering life history switch points through developmental plasticity. Pond drying is an important factor which may alter life history switch points in aquatic organisms.

Hypotheses for the Adaptive Maintenance of Phenotypic Polymorphisms
Ecology and Evolution, Volume 16, Issue 5, May 2026.Phenotypic polymorphisms offer easily observable diversity ideal for empirical and theoretical exploration, but developing and comparing hypotheses for the adaptive maintenance of polymorphism can be a challenge. Here, we propose a framework categorizing polymorphisms based on (i) one of five distinct types of maintenance selection and (ii) the context

The Influence of Climate and Livestock Grazing on Two Species of Burrowing Desert Frogs
Austral Ecology, Volume 51, Issue 3, March 2026.ABSTRACT Frogs are one of the most vulnerable groups of vertebrates globally, occupying a range of environments including arid deserts. They are threatened by many interacting factors, including climate change and livestock grazing. In this study, we present the first long‐term research (over 30 years) on two arid‐dwelling frogs in Australia, the ...

Wildlife Society Bulletin, Volume 49, Issue 3, September 2025.Herpetofaunal camera arrays versus pitfall and funnel trap arrays were tested in upland habitats of Florida, USA, and found that the methods are complementary in recording species richness and abundance; they were also similar in costs of use. Future herpetofaunal field studies should employ both cameras and live traps to best estimate populations and ...

Dietary Diversity and Overlap Between Two Subspecies of Spadefoot Toads (Scaphiopus holbrookii holbrookii and S. h. hurterii) in Arkansas [PDF]
, 1996 The food habits of adult spadefoot toads (Scaphiopus h. holbrookii and S. h. hurterii) collected in Arkansas were exam ined during this study. Thirty-six adult S. h. holbrookii (29 males and 7 females) and 48 adult S. h. hurterii (23 males and 2 females)

Ecosphere, Volume 16, Issue 8, August 2025.Abstract Estimating how close a species is to its upper thermal limits (i.e., warming tolerance, a thermal sensitivity index) and how that proximity changes across space enables spatially explicit identification of species with increased extinction risk as temperatures increase. Yet, thermal sensitivity is often difficult to calculate because it is the
