Solenopsis saevissima (Smith) (Hymenoptera: Formicidae) Activity Delays Vertebrate Carcass Decomposition

Sociobiology, 2017
Ants are among the insects involved in cadaveric decomposition processes, as they exhibit predatory and necrophagous behavior. Red ants exhibit an aggressive behavior, which impacts carcass colonization, accelerates or delays the decomposition rates and ...

Prey density affects predator foraging strategy in an Antarctic ecosystem

Ecology and Evolution, 2020
Studying the effects of prey distribution on predator behavior is complex in systems where there are multiple prey species. The role of prey density in predator behavior is rarely studied in closed ecosystems of one predator species and one prey species,

Zoologia (Curitiba), 2009
Land flatworms are carnivorous, mainly predators. However, knowledge on their predatory behavior and prey preference is very scarce. This paucity of data is a limiting factor in the study of their biology and organismal ecology, resulting in a very ...

Competition or Predation? Schumpeterian Rivalry in Network Markets [PDF]

We explore the logic of predation and rules designed to prevent it in markets subject to network effects. Although, as many have informally argued, predatory behavior is plausibly more likely to succeed in such markets, we find that it is particularly ...
