The neuroecology of competitor recognition.
Territorial animals can be expected to distinguish among the types of competitors and noncompetitors that they encounter on a regular basis, including prospective mates and rivals of their own species, but they may not correctly classify individuals of other species. Closely related species often have similar phenotypes and this can cause confusion when formerly allopatric populations first com...
متن کاملThe neuroecology of chemical defenses.
Chemicals are a frequent means whereby organisms defend themselves against predators, competitors, parasites, microbes, and other potentially harmful organisms. Much progress has been made in understanding how a phylogenetic diversity of organisms living in a variety of environments uses chemical defenses. Chief among these advances is determining the molecular identity of defensive chemicals a...
متن کاملNeuroecology.
Neuroecology is the study of adaptive variation in cognition and the brain. The origin of neuroecology dates from the 1980s, when researchers in behavioral ecology began to apply the methods of comparative evolutionary biology to cognitive processes and the underlying neural mechanisms of cognition. The comparative approach, however, is much older. It was a mainstay of ethology, it has been par...
متن کاملNeuroecology and psychological modularity.
the activity difference δ′ t and the regular temporal difference δ t never substantially affects the plasticity of a synapse. This happens, for instance, if there is only in fact one single reward right at the end of the trial [e.g. r t =0, t < T; r(T)=1]. In a simplification of the version of this that Rao and Sejnowski consider, r(T)=1 comes from an action potential, caused by a privileged in...
متن کاملThe Role of Wing Coloration in Sex Recognition and Competitor Recognition in Rubyspot Damselflies (Hetaerina spp.)
The decision rules that animals use for distinguishing between conspecifics of different age and sex classes are relevant for understanding how closely related species interact in sympatry. In rubyspot damselflies (Hetaerina spp.), the red wing coloration of mature males is hypothesized to be a key trait for sex recognition and competitor recognition within species and the proximate trigger for...
