AbstractParental behavior and effort vary extensively among species. Life-history theory suggests that age-specific mortality could cause this interspecific variation, but past tests have focused on fecundity as the measure ...

Understanding how biotic and abiotic interactions influence community assembly and composition is a fundamental goal in community ecology. Addressing this issue is particularly tractable along elevational gradients in ...

In grassland ecosystems, grazing by large herbivores is a highly influential process that affects biodiversity by modifying the vegetative environment through selective consumption. Here, we test whether restoration of ...

Flight is one of the most effective yet energetically demanding means of movement. its energy costs are normally associated with interspecific variation in efficiency, size of organs, and physiological systems that reflect ...

Familiarity doesn t always breed contempt in tropical songbirds. Animals on tropical mountains often live in narrow elevational bands with similar species above

The Bornean subspecies of Rajah ScopsOwl (Otus brookii brookii) has not been documented alive in the wild since its discovery in 1892 and there are no photographs of the bird in life. We report the rediscovery of this ...

Context. Ungulate life-history strategies and behaviour are driven by two dominant factors, namely, acquisition of nutrients and avoidance of predation. Although many studies have investigated single species resource/habitat ...
