Network analysis offers a rich toolkit to study various graph models in biology. In ecology, centrality indices have been suggested to indicate keystone species in interaction networks and to quantify their importance in an ecosystem. There is a large number of centrality indices, however, and it ...
In subject area: Biochemistry, Genetics and Molecular Biology The keystone species concept is used in ecology to describe individual species with disproportionately large effects on their communities. From: Trends in Ecology & Evolution, 2018

Microbial Co‐occurrence Patterns and Keystone Species in the Gut Microbial Community of Mice in Response to Stress and Chondroitin Sulfate DisaccharideDetecting microbial interactions is essential to the understanding of the structure and function of the gut microbiome. In this study, microbial co-...
Rowett Institute of Nutrition and Health, Bucksburn, Aberdeen, UK The release of energy from particulate substrates such as dietary fiber and resistant starch (RS) in the human colon may depend on the presence of specialist primary degraders (or 'keystone species') within the microbial community....
an ecosystem may experience a dramatic shift if a keystone species is removed, even though that species was a small part of the ecosystem by measures of biomass or productivity. It became a popular concept in conservation biology.这句话更进一步形象的说明了什么是 Keystone。你如果仔细观...
A keystone in an arch's crown secures the other stones in place. Keystone species play the same role in many ecological communities by maintaining the structure and integrity of the community.
Keystone species are organisms that other species in the ecosystem depend upon and whose disappearance would devastate their biological communities. Learn how to define keystone species and review examples of why they are vital to their ecosystems. ...
If a species is a keystone species, should greater attention be paid to conservation of that species than others in a habitat? Conservation: Conservation is a concentration within the field of biology that is concerned with the protection of sp...
