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,...

0 Species richness typically increases with the number of individuals sampled\ although many ecological processes that in~uence species richness are also well known to depend on density of individuals[ We separated the e}ects of density on species richness that are due to sampling\ from those due to density!dependent ecological processes such as competition or predation\ by manipulating the den...

Species diversity includes two aspects, the number of species (species richness) and the proportional abundances of the species (heterogeneity diversity). Species richness and heterogeneity diversity can be measured over different scales; a single point, samples, large scales, biogeographical provinces and in assemblages and habitats. In the literature, the terminology of these scales is confus...

Spatial variability in species richness has been postulated to depend upon environmental factors such as climatic variability, Net primary productivity and habitat heterogeneity. The Advanced Very High Resolution Radiometer (AVHRR)-Normalized Difference Vegetation Index (NDVI) has been shown to be correlated with climatic variability, Net primary productivity and habitat heterogeneity. Moreover...

gradual decrease of biodiversity related to the rapid industrialization and urbanization is stimulating the fundamental research towards a better understanding of the relationships between biodiversity and ecosystem functioning. present study emphasizes the nature and status of floral diversity in the vicinity of integrated industrial estate-pantnagar, uttarakhand, india (iie-pantnagar).three m...

Tilapia is the second most farmed fish in tropical and sub-tropical countries worldwide. This study investigated effect of replacing meal by Spirulina platensis (groups fed with 5%, 10% 15% Spirulina) on growth Nile tilapia O. niloticus juveniles. Intestinal microbiota has been studied MiSeq Illumina sequencing. No significant differences (P > 0.05) were observed for protein, carbohydrate li...

1. The shallow ponds of the nature reserve ‘De Maten’ form a metacommunity, in which individual ponds are highly interconnected via a system of overflows and rivulets. This study reports on the relations between cladoceran species richness and (a) connectivity patterns and (b) local environmental variables. 2. No relation was found between local species richness and three connectivity variables...

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 purpose of this study is to determine the woody species diversity in Sweet chestnut tree, Hazel-tree and Italian cypress ecosystems in the Guilan forests. A lozeng 0.5 ha sample plot was selectively established on each site. In the Sweet chestnut ecosystems , 4 sites were classified, whereas 10 sites of Hazel tree and Italian cypress ecosystems were classified based on species composition. ...
