CONSEQUENCES OF HABITAT TRANSITIONS ON LOCOMOTIVE TRAIT DIVERSIFICATION AT THE MICRO- AND MACRO-EVOLUTIONARY SCALES
(2015-05-08)
Contemporarily evolving systems provide a unique opportunity to characterize the direction, pattern, and rates of phenotypic change among multiple species. The damming of streams to create reservoirs results in a change ...
Parental investment and offspring sex ratios in house sparrows, Passer domesticus and cattle egrets, Bubulcus ibis.
(1998)
Fisher (1930) argued that parents should invest equally in the two sexes. Since then, others have proposed conditions under which parents might be selected to bias their investment in favor of either sons or daughters. I ...
Evolutionary and environmental effects on thermoregulation among complex lizard communities.
(2002)
A community of ten sympatric lizard species was studied in a mountain canyon in southern Arizona to determine the effect of phylogeny on habitat use and thermoregulation. Habitat use, body temperatures ( Tb) and operative ...
Effects of lipopolysaccharide, antipyrogen, and body condition on the chronopharmacology of fever in Dipsosaurus dorsalis.
(2006)
I examined the effects of two doses (2.5 mg kg-1 and 25 mg kg-1) of a pyrogen (lipopolysaccharide, LPS) independently and in combination with an antipyrogen (acetylsalicylic acid) at two times of injection (noon and midnight) ...
Crustacean hormone nuclear receptors: Characterization, gene expression, and evolution.
(1998)
Ecdysteroids are the arthropod molting hormones that control molting and limb regeneration in crustaceans. The actions of ecdysteroids are mediated through their nuclear receptor, ecdysteroid receptor (EcR). Studies in ...
Community ecology of water-filled tree holes in Panama.
(1999)
Water-filled tree holes are phytotelmata formed when rain collects in branch crotches and other wood-lined cavities. Repeated surveys of natural and artificial water-filled tree holes on Barro Colorado Island (BCI), Panama, ...
Distribution and occurrence of carnivores in the Oklahoma panhandle.
(2000)
Five carnivore species representing three families were detected sufficiently to permit analysis. Carnivores were, in general, not distributed evenly over regional, landscape and local scales in the panhandle environment. ...
