Jun 25, 2017 · Biogeography refers to the distribution of various species and ecosystems geographically and throughout geological time and space. Biogeography is often studied in the context of ecological and historical factors which have shaped the geographical distribution of organisms over time.
This chapter elucidates the various means that migrants use to find their way. They range from relatively simple orientation to chemical cues to very complex chronobiological interactions between circadian rhythms, sensory inputs, and the brain. Migrants use several cues.
Feb 23, 2024 · Dispersal is a fundamental process in biogeography, encompassing the movement of species across geographic barriers. It exemplifies the ways in which organisms colonize new habitats, expanding their range through various dispersal mechanisms, ranging from active movements to passive transport by external forces. Extinction
biogeography, the study of the geographic distribution of plants, animals, and other forms of life. It is concerned not only with habitation patterns but also with the factors responsible for variations in distribution.

Before proceeding to a full discussion of migratory behaviour and its evolution and ecology, I shall briefly define and describe movements and related behaviors that organisms display, including some examples and an adumbration of their roles in life cycles (Table 1-1).
May 25, 2022 · Conceptually, movement began to draw attention in modern ecology because of its implications for reproduction, gene flow, and metapopulation dynamics; as such, studies on animal and plant dispersal constituted a large portion of the ecological literature on movement until the early 2000s [3, 4, 5].
