17 lip 2014 · Migration is a dramatic behaviour distinct from other movements. It is an important component of life histories of biodiverse organisms including terrestrial and marine vertebrates, insects, many invertebrates, and the propagules of some plants.
This chapter defines migration as a function of its physiological and behavioral characteristics and how natural selection acts on these. Migration is then described in terms of its ecological outcomes. The pioneering studies of J. S. Kennedy on migratory aphids are discussed, showing how migration can be experimentally characterized.
1 lut 2007 · The scheme links the environment, pathways, traits, and genes, and highlights the selective forces that shape and maintain migratory adaptation. We endorse an individual-based behavioral definition of migration that allows an objective distinction between migration and other forms of movement.
Emigration is the process of leaving one country or region to settle in another. It plays a significant role in shaping population dynamics, influencing genetic diversity, and affecting the overall gene pool of populations.
Animal migration has fascinated humans for millennia. And for good reason: Some of the most astonishing feats of endurance are performed by long-distance migrants, such as the nine-day non-stop...
12 wrz 2014 · Genomics is unraveling the migratory history of modern humans. Knowledge about how they adapted to new environments and pathogens has implications for human health today and may also help to counte...
10 wrz 2018 · Main Text. Migration typically consists of two main phases: locomotion — when distance is covered and energy is consumed — and fuel deposition — when energy reserves are accumulated and restored. Energy accumulation often takes place during stopovers, and migration thus involves alternating stopover and transport periods (Figure 2).
