Ecological multi-trophic communities

Tóm tắt báo cáo

Multi-trophic communities are interesting because species
within a trophic level can coexist in the absence of dispersal, but
the operation of such coexistence mechanisms varies over space and
time. There is thus the potential for simultaneous operation of local
and spatial coexistence mechanisms, a situation that is typically not
considered in spatial ecology. Intraguild predation (IGP), a
multi-trophic interaction that is widespread in nature illustrates
this situation well. Intraguild Predation results when two consumer
species competing for a common resource also engage in a trophic
interaction where one species can prey on or parasitize its
competitor. I this talk, we present and investigate some working IGP
models.
