In tropical rainforests, light is abundant above the canopy but scarce in the understory, only becoming abundant when trees fall over (or lose their leaves) and then only for short periods. Efficiently capturing

The presence of the same putatively adaptive haplotypes on several transects could either reflect: (i) standing variation being repeatedly selected in the highlands or shared via intraspecific gene flow, or (ii) recruitment of adaptations from other high-altitude adapted species through introgression. ...

Skeletal muscle undergoes atrophy and loss of force during long space missions, when astronauts are persistently exposed to altered gravity and increased ionizing radiation. We previously carried out mass spectrometry-based proteomics from skeletal muscl
Finally, although we may have stumbled about blindly in our million years of feverish adaptation, and while we now find ourselves boxed in, with little hope for anything like utopia, there is no cause for shame. If we are awkward and uneven in our adaptations, it is because we are a peo...
Research has shown that animal and humans habituate on a variety of behavioral and physiological responses to repeated presentations of stimuli, such as food cues.Citation71 In animal studies, analysis of habituation is widely used to characterize cognitive phenotypes and such study now covers even ...
ERVs have been extensively studied in humans [26], but their exploration in livestock species remains relatively understudied. Small ruminants like sheep and goats [27,28], along with koalas [29,30] and a few other vertebrate hosts [31,32], provide a unique paradigm of coexistence between en...

trajectories of speciating parasites. On one hand, they share physiology and host-specific adaptations, which may predispose them to evolve along common lines, particularly in allopatry. On the other hand, selective regimes may be less predictable, or even disruptive, in the case of character ...
