Analyses of the movements and web—site characteristics desert spider Agelenopsis apera (Gertsch) demonstrate that web locations offering following habitat features are actively selected: shrubs, depressions, litter, flowering herbs. A model effects thermal environment prey avalability on reproductive success spiders occupying various types is developed. The estimated productivity for an excellent site (grassland depression with attractants) 13x determined a poor (larva surface). Model...
ABSTRACT Describing future habitat for sensitive species can be helpful in planning conservation efforts to ensure persistence under new climatic conditions. The Gila monster ( Heloderma suspectum ) is an iconic lizard of the southwestern United States. northernmost range monsters Mojave Desert, area experiencing rapid human population growth and urban sprawl. To understand current potential we fit ensemble distribution models using known locations environmental variables important species'...
We have extended the analyses of Pimm et al. on risks extinction to include attributes environment, as well species characteristics, potential determinants risk extinction. find their earlier conclusion that large-bodied are at greater high population sizes is not supported by data, nor contention more variable populations Our suggest small small-bodied birds oceanic islands vulnerable than large protected islands. Moreover, a significant interaction body size with type island (channel vs....

Field observations and biophysical models were combined to analyze sleeping—site selection by Galapagos land iguanas (Conolophus pallidus). Iguanas slept in different kinds of sleeping sites during seasons. In the coolest season (garua), adults found that warmer than a available. This may be because garua (cool, overcast, foggy) is time when environmental conditions mitigate against rapid warm—up mornings, so lizards regulate nighttime body temperatures it easier warm up preferred daytime...
Body size and morphology are important traits that can strongly influence the life history of an organism. One factor affecting these is habitat. Urbanization has resulted in significant modification many habitats, thus, it may be a body species living urban environment. In this study, we compared bush populations lizard Lophognathus temporalis around Darwin, Australia. We made monthly measurements invertebrate abundance soil moisture during one year to compare seasonal variation resource...
The California Department of Fish and Wildlife (CDFW) provided research funds to study the conservation genomics landscape Mojave desert tortoise, Gopherus agassizii, in response Desert Renewable Energy Conservation Plan (DRECP). To do this, we consolidated tissue samples tortoise from across species range within southern Nevada, generated a DNA dataset consisting full genomes 270 tortoises, analyzed way which environment has determined modern patterns relatedness genetic diversity...
1. Research on water exchange in frogs has historically assumed that blood osmotic potential drives between a frog and its environment, but here we show the “seat patch” (the primary site of many anurans), or other sites cutaneous uptake, act as an anatomic “compartment” with controlled separately from blood, compartment can be driver animal environment. 2. We studied six species (Xenopus laevis, Rana pipiens, R. catesbeiana, Bufo boreas, Pseudacris cadaverina P. regilla) differing...
