Exotic invaders gain foraging benefits by shoaling with native fish
Freshwater habitats are under increasing threat due to invasions of exotic fish. These invasions typically begin with the introduction of small numbers of individuals unfamiliar with the new habitat. One way in which the invaders might overcome this disadvantage is by associating with native taxa occupying a similar ecological niche. Here we used guppies (Poecilia reticulata) from a feral popul...
متن کاملNative communities determine the identity of exotic invaders even at scales at which communities are unsaturated
Biological invasions are one of the largest ecological and economic problems we face. Invasive species represent one of the most significant threats to biological diversity, along with habitat loss and fragmentation (Wilcove et al., 1998; Pimentel et al., 2000). Thus, any knowledge we can contribute to understanding the process of invasion will have huge benefits for humanity. In particular, id...
متن کاملBenefits of kin shoaling in a cichlid fish: familiar and related juveniles show better growth
Group living is widespread in animals. In nature, groups usually not only differ in phenotypic characteristics but also in the social relationships among group members. Theory predicts that individuals adjusting their shoaling decisions—to join certain groups or not—based on social criteria, such as familiarity or genetic relatedness, can increase their fitness. Although numerous studies report...
متن کاملRelative competence of native and exotic fish hosts for two generalist native trematodes
Exotic fish species frequently acquire native parasites despite the absence of closely related native hosts. They thus have the potential to affect native counterparts by altering native host-parasite dynamics. In New Zealand, exotic brown trout Salmo trutta and rainbow trout Oncorhynchus mykiss have acquired two native trematodes (Telogaster opisthorchis and Stegodexamene anguillae) from their...
متن کاملRelative Foraging Value to Lesser Scaup Ducks of Native and Exotic Clams from San Francisco Bay
Invasions of exotic invertebrates have greatly altered many aquatic communities, but impacts on the foraging energetics of predators seldom have been assessed. In San Francisco Bay, California (USA), a major community change occurred with introduction of the Asian clam (Potamocorbula amurensis) in 1986. This species now greatly outnumbers the previous clam prey of a variety of sharks, rays, stu...
