Group-living is widespread among vertebrates and is expected to provide benefits such as decreased predation, enhanced feeding success, and higher survival of young ones (for example, Holekamp et al. 1997, Clutton-Brock ...

The wide diversity in social structures is thought to be the result of selection for individual behavioural strategies and inter-individual interaction patterns that maximise fitness under different environments (van ...

Behavioural and physiological mechanisms have evolved to adapt to the cyclic variations in the environment and adjust to the temporal sequence of events present on earth (Moore-Ede and Sulzman 1981) (Sharma 2003) (Vaze and ...

When a cat detects prey, it stalks the prey before attacking it. Prey detection, thus, causes the cat to perform a series of non-random actions to conceal itself and capture the prey. These non-random actions are repeated ...

For most of their historical development as distinct fields of biology, population ecology and population genetics have remained largely separate (Kingsland 1995, Mueller 1997), even though they have had obvious overlaps ...

The motivation for this simulation study is the realization in our laboratory over the past several years that experimental populations of Drosophila subjected to larval crowding every generation can actually evolve ...

Nearly all organisms on Earth are subject, in one way or the other, to the effects of the planet’s daily rotation about its axis and need to adjust their physiology and behaviour to the daily cycling of environmental ...

Previous studies in the laboratory have shown that expression of pathogenic human Huntingtin (HTT-Q128) in circadian pacemaker neurons (ventro lateral neurons, LNv) of Drosophila, leads to immediate behavioural arrhythmicity ...

Sleep is a period of quiescence that is widespread in the animal kingdom and while its quantity and quality may differ between different animals, certain characteristic features remain conserved across taxa. These include ...
