Passive sub floor dispersal layer
WebThe generalized gravity model predicts passive directed dispersal in plant–animal dispersal relationships when (i) animal vectors are predictably attracted to specific destinations, (ii) animal vectors disproportionately disperse propagules to those destinations, and (iii) those destinations are also favourable microsites for the dispersed plants. Our literature search … WebPassive dispersal simply refers to a physical sloughing event brought on by external forces such as fluid and solid shear, and mechanical interventions (e.g., tooth brushing). ...

Dispersal is an important life-history trait that plays a key role in the demography and evolution of populations and species (reviews [ 1 – 4 ]). It can be defined as the movement of individuals between natal and subsequent breeding sites, either passively or actively. The causes of dispersal remain a topic of study, but they ...

Webthe ocean and simulate larval dispersal. They choose where the “larvae” are released, how long they remain in the water column, and what depth they disperse at. Model results can be used to predict where larvae might disperse.
