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 ...

Food webs, descriptions of who is eating whom in an ecosystem, are one of the most enduring and influential concepts in ecology. An increasing number of studies are including parasite-host feeding interactions in food webs, each providing evidence that parasites alter our perception of food web structure. Amundsen et al. in this issue report intriguing

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.

Abstract For nonrandom models of species interaction there is a precipitous decrease in stability as connectance increases. However, the range of stability for different models of the same connectance is large; stability also depends on how the species interactions are organized. Systems with species feeding on more than one trophic level (omnivores)

Food Terrorism and Food Defense on the Web
Medical Reference Services Quarterly, 2008Global food supplies are at risk of both accidental and deliberate contamination. As past incidents have demonstrated, food terrorism may cause social, economic, and political disruption. The United States increased its efforts to protect its food after 9/11 by broadening the roles of existing agencies, including the U.S.

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 ...
