Abstract In the past ten years the ability to leverage modern computational approaches with the increasing quantity of digitized archaeological data has enabled the analysis of archaeologically informed ecological networks. Food webs are a type of ecological network that represent the trophic interactions, or consumption links, within ...

Do large organisms occupy higher trophic levels? Predators are often larger than their prey in food chains, but empirical evidence for positive body mass–trophic level scaling for entire food webs mostly comes from marine communities on the basis of ...

Intraguild predation enhances biodiversity and functioning in complex food webs.
Ecology, 2019Intraguild predation (IGP), that is, feeding interaction between two consumers that share the same resource species, is commonly observed in natural food webs.

Microbial food chains and food webs
Journal of Theoretical Biology, 1973Abstract Mathematical models for simple microbial food chains and food webs in continuous culture are developed and analyzed. A model for competition of two microbial species for a single scarce resource is also presented as a degenerate case of the food web model. Two models for food chains are developed.

In each water mass a different amount of organic matter and inorganic salts is dissolved; some waters will be well fertilized with plant foods, others more poorly or even barren. There exist desert areas in the oceans as well as on the land. The Sargasso Sea is supposed to be one such desert, and there are others east of Sydney in the Tasman Sea, and ...

Network structure and biodiversity loss in food webs: robustness increases with connectance
Ecology Letters, 2002Food-web structure mediates dramatic effects of biodiversity loss including secondary and ‘cascading’ extinctions. We studied these effects by simulating primary species loss in 16 food webs from terrestrial and aquatic ecosystems and measuring ...
