“…Phytoplankton species were identified according to the following manuals, keys and papers: [28][29][30][31][32][33][34][35][36][37][38][39][40]. In addition, zooplankton taxa were identified using the following principal taxonomic references: [41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57]. Furthermore, identification of zoobenthos were performed according to: [58,59] for insects; [60][61][62][63]; for identification of Oligochaetae: [64,65] for Mollusca; [66] was mainly used for identification of chironomid larvae.…”

Major biological parameters along with nutrient concentrations of the Nile in Upper Egypt were analyzed during 2007 for a better understanding of community structure and diversity of the main functional groups of organisms. The abundance of plankton and zoobenthos was followed seasonally. Altogether 168 taxa (85 phytoplankton, 43 zooplankton and 40 zoobenthos) were encountered from the Nile in Upper Egypt. The combined contribution of chironomid larvae, Mollusca and Oligochaetae represented the abundant groups of the Nile zoobenthos throughout the study period. The results of this study suggested that the sediment contents of organic matter and CaCO 3 , as well as water temperature and NO 3-N concentrations, seemed to be important in determining the abundance and biomass of zoobenthos. Most importantly, the results of this study will provide valuable information for river management. Simultaneously; alpha, beta, gamma and Shannon (H̀) diversities of these communities were measured. Alpha and gamma diversities for

“…Many studies have been undertaken on the subject of the processes that determine which and how many rotifer species live in a specific habitat (community assembly). Predation (Gilbert & Williamson, 1978;Stemberger & Evans, 1984;Williamson & Butler, 1986;Green, 2001;Dieguez & Gilbert, 2002), interference from cladocerans (Gilbert, 1988;MacIsaac & Gilbert, 1989;Pace & Vaque, 1994;Arvola & Salonen, 2001;Nandini et al, 2002), and food availability (Stelzer, 2001;Duggan et al, 2002), as well as other abiotic factors such as temperature, salinity or acidification (Guisande & Toja, 1988, Arnott & Vanni, 1993Devetter, 1998), have often been cited as relevant factors in determining rotifer assemblages.…”

Identification of the main factors in structuring rotifer community assemblages in the ponds of Do ñana National Park using the amino acid composition of the speciesThe use of the role of the species in the habitat (the niche), as an alternative to systematics for studying the processes that determine which and how many species live in a specific habitat (community assembly), is an approach that has been limited by the difficulties in the characterization of the niche. The aim of this study was to identify the determining factors in rotifers' assemblage in several ponds, using the amino acid composition (AAC) of the species as a fingerprint of the differential niche usage. We found that species with a similar AAC and, hence, with a similar trophic niche, spatially co-exist, showing that trophic-niche differentiation is not a main factor in structuring these lentic associations. The negative relationship between amino acid separation and spatial overlap among rotifer species can be considered as evidence that habitat filtering (abiotic factors) is the factor responsible for the assemblages.
