Passive dispersal
WebApr 12, 2024 · The GD of populations that recover by passive restoration depends on the number of source populations and their distances from the restoration site, the dispersal ability of the target species, and the landscape connectivity among restored and source populations (Lumibao et al., 2016; Lumibao & McLachlan, 2014). WebNov 12, 2015 · ABSTRACT: Boundary currents are spectacular oceanographic features whose role as the main drivers of dispersal is often taken for granted. However, numerous genetic studies of passively dispersing coastal species have challenged this idea, and have identified gene flow in the direction opposite to the currents, pointing to a role of …

WebPassive Dispersal by Parasitic Stages. Parasitic stages are important for dispersal because usually the host can move much greater distances than the parasite would, even if the parasite has a motile stage. This type of dispersal is passive on the part of the parasite, and is successful only if the host is fed upon by another suitable host. ...
WebAug 18, 2024 · Dispersal is a fundamental biological process that operates at different temporal and spatial scales with consequences for individual fitness, population dynamics, population genetics, and species distributions. Studying this process is particularly challenging when the focus is on microscopic organisms that disperse passively, whilst …
