Effects of environmental factors on species diversity of rotifers using biodiversity indicators and canonical correlation analysis (CCA)
Rotifers are microscopic aquatic animals of phylum Rotifera, live in a diverse range of aquatic habitats. They are important in ecology of freshwater ecosystems by recycling nutrients and can alter trophic dynamic of planktonic communities. These features have also been used to infer environmental conditions in an aquatic habitat. Because of the important roles of this group of animals in the t...
متن کاملSolving a tri-objective convergent product network using the Steiner tree
Considering convergent product as an important manufacturing technology for digital products, we integrate functions and sub-functions using a comprehensive fuzzy mathematical optimization process. To form the convergent product, a web-based fuzzy network is considered in which a collection of base functions and sub-functions configure the nodes and each arc in the network is to be a link betwe...

In this study frequency and composition of plankton in Shadegan wetland was carried out in 5 stations during 2007-2008. Genus qualitative identification and their composition and quantitative frequency aspect were studied (for phytoplankton chlorophyll a). Frequency of total 42 genus phytoplankton in 4 classes Bacilariophyceae (Diatom), Cyanophyceae, Chlorophyceae and Dinophyceae are 69.4, 22.2...
متن کاملTree diversity drives diversity of arthropod herbivores, but successional stage mediates detritivores
The high tree diversity of subtropical forests is linked to the biodiversity of other trophic levels. Disentangling the effects of tree species richness and composition, forest age, and stand structure on higher trophic levels in a forest landscape is important for understanding the factors that promote biodiversity and ecosystem functioning. Using a plot network spanning gradients of tree dive...
