Food Terrorism and Food Defense on the Web

Medical Reference Services Quarterly, 2008
Global 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.

Food and Food Webs

1975
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 ...

Food webs in food webs: the micro–macro interplay of multilayered networks

Trends in Ecology & Evolution
Food webs are typically defined as being macro-organism-based (e.g., plants, mammals, birds) or microbial (e.g., bacteria, fungi, viruses). However, these characterizations have limits. We propose a multilayered food web conceptual model where microbial food webs are nested within food webs composed of macro-organisms.

Modeling the microbial food web

Microbial Ecology, 1994
Models of the microbial food web have their origin in the debate over the importance of bacteria as an energetic subsidy for higher trophic levels leading to harvestable fisheries. Conceptualization of the microbial food web preceded numerical models by 10-15 years. Pomeroy's work was central to both efforts.

Food Webs for Parasitologists: A Review

Journal of Parasitology, 2010
This review examines the historical origins of food web theory and explores the reasons why parasites have traditionally been left out of food web studies. Current paradigms may still be an impediment because, despite several attempts, it remains virtually impossible to retrofit parasites into food web theory in any satisfactory manner.

Is biodiversity maintained by food-web complexity?—the adaptive food-web hypothesis

2005
Abstract How do diverse species coexist in the complex networks of prey-predator interactions in nature? While most theoretical models predict that complex food webs do not persist, recent empirical studies have revealed the very complex structure of natural food webs.
