Traditional farm tools observed from an ecological and health perspective

Chemical warfare from an ecological perspective.

C weapons are recent acquisitions in humankind’s ever-growing arsenal of destruction. But bacteria and fungi have been practicing chemical warfare for a very long time. Among the numerous and structurally diverse antimicrobial agents that microbes produce are penicillin by the mold Penicillium notatum, many important antibiotics by streptomycetes, a wide range of bacteriocins by Escherichia col...

Farm animal genetic and genomic resources from an agroecological perspective

and Zerjal T (2015) Farm animal genetic and genomic resources from an agroecological perspective. Agroecology, as a scientific approach, relies on a better knowledge of biodiversity at all levels of organization and function, in order to better manage agricultural production systems, from farm scale to landscape. Ecological concepts such as functional redundancy, complementary use of resources,...

Antibiotics: an ecological perspective

The effects of antibiotics on the indigenous microbes of the gut have been the subject of extensive study ever since the discovery of these drugs in the 1940s and their subsequent commercial production. Yet nearly all of this work has concerned the effects of individual antibiotics on individual, cultivated strains of bacteria in the laboratory, or on specific species of bacteria cultivated fro...
