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 کاملCould temperature and water availability drive elevational species richness patterns? A global case study for bats
Aim A global meta-analysis was used to elucidate a mechanistic understanding of elevational species richness patterns of bats by examining both regional and local climatic factors, spatial constraints, sampling and interpolation. Based on these results, I propose the first climatic model for elevational gradients in species richness, and test it using preliminary bat data for two previously une...
متن کاملElevational Gradients in Species Richness
The abiotic and biotic gradients on mountains have enormous potential to improve our understanding of species distributions, species richness patterns and conservation. Here we describe how abiotic factors change with elevation, how flora and fauna respond to these changes and how elevational species richness patterns have been studied to uncover drivers of biodiversity. There are four main tre...
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 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...
