Deleting species from model food webs

Article Abstract:

The disappearance of one species could have knock-on effects causing extinction of further species from the food web in natural biological communities. An evolutionary model was used to assemble many independent simulated food webs, and their dynamical behavior was studied after deleting one species, to investigate these effects.

Phenotypic plasticity in gender specific life-history: Effects of food availability and predation

Article Abstract:

A study is conducted to test the impact of two biotic factors in combination (presence/absence of predators and low /high food level) on gender specific life-history traits in the damselfly. The result shows that predator presence and low-food density decreased activity in both sexes.

Field biology, food web models, and management: challenges of context and scale

Article Abstract:

The author discusses the use of food web and food chain models in providing iterative feedback in wildlife management research. These models are most effective when they adhere strictly to local natural history and take into consideration spatio-temporal variation.
