Sexual cannibalism, the consumption of the male by the female before, during, or after
mating, can be a striking example of sexual conflict with potentially large fitness …

Understanding the mechanisms that result in the success of introduced species will
contribute to predicting future invasions and managing invaded systems. We examined …

In the crab spider, Misumena vatia, Douglass H. Morse and his colleagues found an ideal
species on which to test basic questions associated with lifetime fitness. From the moment a …

1. Antagonistic interactions among invertebrate predators such as intraguild predation and
cannibalism have the potential to dampen top‐down impacts on shared prey at lower trophic …

Niche differentiation and intraguild predation (IGP) can allow ecologically similar species to
coexist, although it is unclear which coexistence mechanism predominates in consumer …

Most taxa show consistent individual differences in behavior, a phenomenon often referred
to as animal “personalities.” While the links between individual personality and fitness have …

Hypogean habitats are relatively simple exhibiting low diversity, low production and relative
constancy of environmental factors, and are therefore appropriate for studying species …

Sexual cannibalism varies widely among spiders, but no general evolutionary hypothesis
has emerged to explain its distribution across taxa. Sexual size dimorphism (SSD) also …

Abstract Theory indicates that competing species coexist in a community when intraspecific
competition is stronger than interspecific competition. When body size determines the …

Fishing spiders (Dolomedes spp.) make an interesting model to predict the impact of global
changes because they are generalist, opportunistic predators, whose distribution is driven …
