Factors Affecting Juvenile Movement in a House Sparrow Metapopulation

摘要: Dispersal propensity can vary considerably between individuals in a population. Understanding which disperse- and under what circumstances these disperse is valuable for conservation. Factors influencing juvenile movement natal dispersal were studied individually marked house sparrows, Passer domesticus, an archipelago off the coast of Helgeland, northern Norway. Sex, clutch size, body size mass did not significantly explain variation movement. Movement rate was however negatively related to hatch date on one islands. Moreover, there decrease with increasing patch isolation hostility matrix habitat. This study suggests that habitat configuration important factor determining environment experienced early life may be propensity. I strongly recommend incorporating landscape features further analyses rate.
