Large branchiopod assemblages common to Mexico and the United States

Distribution and assemblages of large branchiopods (Crustacea: Branchiopoda) of northern Western Ghats, India

“…This index is calculated as a measure of co-occurrence for the branchiopods observed in a species assemblage (Maeda-Martínez et al, 1997). The index is calculated by the formula:…”

“…Large branchiopod assemblage pattern table format was adopted from Maeda-Martínez et al (1997). Mapping was carried out using DIVA-GIS (v7.5) freeware (www.diva-gis.org).…”

“…These animals are found in characteristic assemblages with representatives of a few or mostly all orders co-habiting a single habitat with up to 10 species found in a single site (Thiéry, 1991;Maeda-Martínez et al, 1997). Many factors are known to influence branchiopod assemblages including habitat type, size of the water body, hydroperiod, pH, salinity and temperature and biotic conditions such as vegetation presence, competition and predation (Thiéry, 1991;MaedaMartínez et al, 1997 and references therein;Boven et al, 2008).…”

Various aspects of such assemblages have been investigated from the temperate regions of the old world and the new (Hamer and Appleton, 1991a;Thiéry, 1991;Maeda-Martínez et al, 1997;Petrov and Cvetković, 1997;Eder et al, 1997;Hamer and Martens, 1998;Thiéry and Puente, 2002;Marrone et al, 2006;Boven et al, 2008;Waterkeyn et al, 2009). However, limited information is available from the Oriental biogeographical region, including India.…”

New locality records and additional information on habitats of three species of clam shrimps (Crustacea: Branchiopoda) from a region in northern part of Western Ghats (Sahyadris), India

“…Since then, many studies have shown that, even within the different groups of large branchiopods, coexistence is not uncommon (Maeda-Martinez et al 1997). MaedaMartinez et al(1997) further summarised all potential factors facilitating large branchiopod coexistence and divided them into three categories: (i) habitat factors, (ii) species factors and (iii) historic factors.…”
