Density-dependent indirect effects: apparent mutualism and apparent competition coexist in a two-prey system
A predator consuming multiple prey species usually causes indirect effects. Ap parent mutualism results when multiple prey species reduce predation risk for each other by altering a predator’s functional response. Short-term apparent competition occurs when multiple prey species increase predation risks for each other through the numerical response, i.e. increasing the predator’s birth rate, or...
متن کاملApparent competition and insect community structure: towards a spatial perspective
Competition has been widely discussed as a process that may structure communities of plants and animals. Its role in insect communities is less clear, especially as many insect species do not appear to compete for resources. However, such communities could still be structured by “apparent competition” where the species interact through shared natural enemies. We explore recent attempts to asses...

Bringing to light the difference between birth and nation, the refugee causes the secret presupposition of the political domain—bare life—to appear for an instant within that domain. In this sense, the refugee is truly ‘the man of rights,’ as Arendt suggests, the first and only real appearance of rights outside the fiction of the citizen that always covers them over. Yet this is precisely what ...
متن کاملSpecies Introduction and Replacement among Mosquitoes: Interspecific Resource Competition or Apparent Competition?
Mechanisms by which an introduced container-dwelling mosquito, Aedes albopictus, may cause declines in a resident container-dwelling mosquito, Aedes aegypti, in South Florida were tested using a combination of field experiments and field observations. Field experiment 1 tested which species has a competitive advantage as larvae developing in water-filled tires. Densities and availability of res...
متن کاملDynamics of a generalized Beverton-Holt competition model subject to Allee effects
In this article, we propose a generalized Beverton-Holt competition model subject to Allee effects and study its population dynamics to obtain insights on how the interplay of Allee effects and contest competition affects the persistence and the extinction of two competing species. By using the theory of monotone dynamics and the properties of critical curves for non-invertible maps, our analys...
