Effect of dispersal at range edges on the structure of species ranges

Article Abstract:

A single species population dynamics model is used on a coupled-lattice to determine the effects of dispersal on population sizes at the edge of a range without confounding gradients in environmental conditions. The results have shown that habitat conversion not only decreases the total population by the equivalent of lost carrying capacity but also by jeopardizing populations at the newly formed edge.

Aerial dispersal of phytoseiid mites (Acari: Phytoseiidae): estimating falling speed and dispersal distance of adult females

Article Abstract:

Research on the distribution of adult female mites (Acari: Phytoseiidae) showed that the seed dispersal model that incorporates wind speed, duration, and vertical eddy effects is a closer match to mite dispersal in greenhouse, wind tunnel and field studies than seed dispersal models that rely on weight.
