abstract information about the spatial patterns of soil biodiversity is limited though required, e.g. for understanding effects of biodiversity on ecosystem processes. this study was conducted to determine whether soil macrofauna biodiversity parameters display spatial patterns in the riparian forest landscape of karkhe. soil macrofauna were sampled using 200 sampling point along parallel trans...

Various properties have been advocated for biological evenness indices, with some properties being clearly desirable while others appear questionable. With a focus on such properties, this paper makes a distinction between properties that are clearly necessary and those that appear to be unnecessary or even inappropriate. Based on Euclidean distances as a criterion, conditions are introduced in...

Moth species were studied from some selected districts of Assam (i.e., Cachar and Barpeta district) to determine their diversity index, species richness and evenness of Arctiidae and Geometriidae family of the moth fauna.The moths were collected by applying specialized trapping methods using UV light operating during night. Collected moth species were identified up to family-genusspecies level....

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,...

Among the most popular of metrics used to quantify landscape composition are Shannon’s index, believed to emphasize the richness component of diversity, and Simpson’s index, emphasizing the evenness component. These indices can show considerable variation in response to changes in landscape richness and evenness. However, the possibility of encountering opposite trends in the responses of these...

the aim of this investigation was to study the planktonic shrimp-like communities density and diversity in artificial reefs of khuzestan coasts, bahrakan waters (the persian gulf). sampling was conducted for one year from may 2011 to april 2012, monthly. zooplankton were collected with plankton tows using 300 μm mesh net. totally, two superfamily, penaeoidea, sergestoidea and one suborder carid...
