Biological diversity comprises both species richness, i.e., the number of species in a community, and evenness, measuring how similar species are in their abundances. The relationship between species richness and evenness (RRE) across communities remains, however, a controversial issue in ecology bec...
A symbiotic relationship is an interaction between two or more species in which one species lives in or on another species. There are three main types of symbiotic relationships: parasitism, commensalism, and mutualism. The first and the third can be key factors in the structure of a biological...
Species richness is an indicator of species diversity. It is of great significance to study the relationship between species richness and environmental factors on the development, planning and management of nature reserve.Nineteen nature reserves in Guangdong province with detailed background data were se...

Symbiosisis any type of acloseandlong-term biologicalinteraction between twodifferent biological organisms, be itmutualistic,commensalistic, orparasitic. The organisms, each termed asymbiont, must be of different species. In 1879, Heinrich Anton de Bary defined it as "the living together of unlike ...
ENERGY PARTITIONING BETWEEN DIFFERENT‐SIZED ORGANISMS AND ECOSYSTEM STABILITY (2) population interactions, including carrying capacity, rates of competition and predation, and patterns of species diversity; and (3) ecosystem processes, including rates of biomass production and respiration and patterns of ...
So, any close relationship between two organisms of different species would be considered a symbiotic relationship, including positive and negative relationships. Mutualism then is a kind of symbiosis, a specific type of symbiotic relationship where both organisms benefit somehow. ...
However, the relationship between plant diversity and microbial functional diversity along broad spatial gradients at a large scale is still unexplored. In this paper, we examined the relationship of plant species diversity with soil microbial biomass C, microbial catabolic activity, catabolic diversity ...
Virtually everymovement disorderhas been reported in patients withMS. Some of these case reports provide supportive evidence towards a “cause and effect” relationship between MS and the movement disorder, while others report a coincidence of two different diseases in one individual. Abnormal movements...
