Do spiders respond to global change? A study on the phenology of ballooning spiders in Switzerland

We studied ballooning spiders captured weekly over an 11-y period using a 12.2-m-high suction trap in an agricultural landscape of western Switzerland. We analyzed population trends, changes in phenology, and species composition. Yearly trends in population size of the most abundant species were studied with nonparametric correlations. We found that these trends were markedly different for grou...

Flying Spiders: Simulating and Modeling the Dynamics of Ballooning

Spiders use a type of aerial dispersal called “ballooning” to move from one location to another. In order to balloon, a spider releases a silk dragline from its spinnerets and when the movement of air relative to the dragline generates enough force, the spider takes flight. We have developed and implemented a model for spider ballooning to identify the crucial physical phenomena driving this un...
