Ecology.a series of organisms interrelated in their feeding habits, the smallest being fed upon by a larger one, which in turn feeds a still larger one, etc. the chain from a food source to the ultimate consumer. a hierarchy ranked by status, importance, influence, etc.: ...
The study of food-chain dynamics, with consumer trophic levels regulating biomass of resources from the "top-down" and resources limiting consumers from the "bottom-up," was once hailed as "the central theory of ecology, at least as important as the theory of evolution" (Fretwell 1987, p....

Agroecology as ecology and social system Let me be clear that regenerative agriculture represents a rightly celebrated step forward. There are also other alternatives that can take us a few more steps forward. And I am sure all of us want that. While regenerative agriculture has gained momentum ...
In the resulting framework, food risks can be defined at the level of the production chain in addition to the individual product, which broadens the range of potential strategies for dealing with the newly framed food risks. 展开 关键词: food safety bse food chain regulatory innovation ...
every node in the network must be reachable by a path from at least one basal node. Food webs satisfy both conditions so the linear system defined by Eq. (7) has a unique solution. Without loss of generality we assignsj = 1 for all basal species, as is the convention in ecology...
FoodOn consortium partners can draw upon the ontology to standardize vocabulary usage in their interest domains of consumer health, nutrition, food safety and security, and environmental ecology resources, as the following use cases demonstrate.

cluster's two most important characteristics are its focus on the wider marine environment and the regional focus on North America. However, the correlation coefficients indicating the significant words for this group are the lowest among all clusters, meaning an overall weaker explanatory power (...
