The diversity of species is an important characteristic of ecological system. What is the significance of species diversity in ecological system? A. Increase the stability of ecological system B. Reduce the competition among species C. Decrease the complexity of ecological system D. Make E. co...
Species Diversity in Ecological Communities - Ricklefs, Schluter - 1993 () Citation Context ...increasing awareness of the extent of the past and of ongoing deforestation and the associated risks of further erosion of genetic, species and ecosystem diversity, have led to numerous studies (e.g. ...
The pattern-diversity of a community is high when the individuals of the various species are thoroughly mingled so that several species are usually present in any small sub-area; it is low if the species are segregated so that small sub-areas are likely to contain individuals of only a few...
The genus Cladosporium is one of the largest genera of dematiaceous hyphomycetes, and is characterised by a coronate scar structure, conidia in acropetal chains and Davidiella teleomorphs. Based on morphology and DNA phylogeny, the species complexes of C
2007b), was used to elucidate species diversity within the C. cladosporioides complex. MATERIAL AND METHODS Isolates Isolates included in this study were obtained from the culture collection of the Centraalbureau voor Schimmelcultures (CBS-KNAW Fungal Biodiversity Centre), Utrecht, Netherlands, or were...
Thus, genetic diversity can have important ecological consequences at the population, community and ecosystem levels, and in some cases the effects are comparable in magnitude to the effects of species diversity. However, it is not clear how widely these results apply in nature, as studies to ...
According to Du Pinggui, director of the provincial forestry and grassland bureau, the plateau's distinctive "grass - river - lake - fish - bird" symbiotic ecological chain is approaching a balanced state. "We will persist in enhancing the diversity, stability, and sustainability of the wetland...
Plant species diversity increases as soil phosphorus availability declines during long-term ecosystem development(1,2). The increase in plant species diversity is associated with a decline in above-ground functional diversity, because le... G Zemunik,BL Turner,H Lambers,... - 《Nature》 被引量...
While the intermittent taxa accounted for the majority of the microbiota diversity, the chronic taxa accounted for the majority of the relative abundance (chronic taxa mean abundance ± SD in the paediatric patients = 77.5% ± 10.1% and adult patients = 71.5% ± 11.4%)...
2021). On a smaller scale, geodiversity was found to explain a portion of the pattern of threatened species richness in Finland's national parks (Tukiainen et al. 2016). While temperature is the main predictor of species richness, the geodiversity indicator variables (e.g., rock type and ...
