Timing is a crucial aspect for survival and reproduction in seasonal environments leading to
carefully scheduled annual programs of migration in many species. But what are the exact …

The “paradox of the great speciators” has puzzled evolutionary biologists for over half a
century. A great speciator requires excellent dispersal propensity to explain its occurrence …

Birds in seasonal habitats rely on intricate strategies for optimal timing of migrations. This is
governed by environmental cues, including photoperiod. Genetic factors affecting intrinsic …

Annual cues in the environment result in physiological changes that allow organisms to time
reproduction during periods of optimal resource availability. Understanding how circadian …

Migration biology is an important chapter of the past decade which includes the wealth and
health of descriptive articles that indicate different kinds of emigrational aspects. We must …

Migration is a behavioral syndrome that integrates morphological, behavioral and
physiological traits. This syndrome exhibits considerable variation within and between …

In evolutionary terms, it is highly probable that if a population belongs to a closed system
and concentrates in one place, it will disappear. Its lower variability, as a result of its lack of …

En términos evolutivos, es altamente probable que si una población pertenece a un sistema
cerrado y se concentra en un solo lugar, ésta desaparecerá. Su menor variabilidad …
