Species richness and evenness in Australian birds.
Species richness and evenness are the two major components of biodiversity, but the way in which they are interrelated is a subject of contention. We found a negative relationship between the two variables for bird communities at 92 woodland sites across Australia and sought an explanation. Actual evapotranspiration (AET) was by far the best predictor of species richness. When AET was controlle...
متن کاملEmpirical Relationships between Species Richness, Evenness, and Proportional Diversity.
Diversity (or biodiversity) is typically measured by a species count (richness) and sometimes with an evenness index; it may also be measured by a proportional statistic that combines both measures (e.g., Shannon-Weiner index or H'). These diversity measures are hypothesized to be positively and strongly correlated, but this null hypothesis has not been tested empirically. We used the results o...
متن کاملDiversity, Species Richness and Evenness of Moth Fauna of Peshawar
Moths were collected from different parts of Peshawar during June to August in 2007 to determine their diversity, species richness and evenness. A total number of 774 moth specimens were collected by using simple light traps operated from dusk to dawn daily for sixty nights. The moths caught were identified up to family level. Families Noctuidae, Pyralidae, Arctiidae, Geometridae, Sphingidae an...
متن کاملSpecies Richness, Evenness and Plant Community Stability 22 Years after Ploughing a Semiarid Rangeland
Rangeland ploughing and cultivation using dry land farming crops may be amajor reason for the destruction of natural resources in the semiarid and sub-humid regionswhich may significantly change the composition and reduce the stability of the affectedcommunities. In present research, an abandoned ploughed site was compared with a nearbyreference site in the semiarid rangelands of Baharkish, Quc...
متن کاملTree species richness decreases while species evenness increases with disturbance frequency in a natural boreal forest landscape
Understanding species diversity and disturbance relationships is important for biodiversity conservation in disturbance-driven boreal forests. Species richness and evenness may respond differently with stand development following fire. Furthermore, few studies have simultaneously accounted for the influences of climate and local site conditions on species diversity. Using forest inventory data,...
