“…Yet, it was also suggested that the crustacean remains might have been derived from exuvia floating in the water and not from living animals. A similar suggestion was also advanced by Royan (1976) for Leptestheriella (Conchostraca).…”

On predatory tendencies in the feeding ecology of the fairy shrimp Streptocephalus proboscideus (Frauenfeld, 1873) (Crustacea: Anostraca)

The feeding habits of the filter-feeding fairy shrimp Streptocephalus proboscideus are documented experimentally by offering them ciliates, Volvox, rotifers, nematodes and small crustaceans as prey . Escape capabilities (e .g . swimming speed) rather than size or shape were found to determine these animals' vulnerability to predation by the fairy shrimp . Ingestion rates for Volvox increased hyperbolically with size and, at the high temperatures in which they live, fairy shrimps may daily remove the equivalent of their body weight from the environment . 119

“…Sometimes Notostraca can also be diggers and sifters of organic bottom material and feed on small animals like Tubificidae (Thiery, 1987). Spinicaudata are also omnivorous (Royan, 1976) but sometimes obtain food by scraping the periphyton attached to vegetation. As the source of food is diversified (benthic bacterial flocks, planktonic ones, detritus, periphyton, small benthic prey..…”

Multispecies coexistence of branchiopods (Anostraca, Notostraca & Spinicaudata) in temporary ponds of Chaouia plain (western Morocco): sympatry or syntopy between usually allopatric species

The study of the structure of communities of Crustacean branchiopods Anostraca, Notostraca and Spinicaudata of temporary ponds in Morocco revealed the existence of a geographical area with a particularly diversified number of species. Over a few hectares, 11 species, among the 18 known in Morocco, are present. While most of them are usually allopatric and belong to distinct associations, indicative of particular ecological and climatic conditions, they can coexist in Chaouia plain, either in adjoining ponds (sympatric species) or in the same pond (syntopic species). In one pond we could find up to 10 phyllopods: 6 Anostraca, 2 Notostraca and 2 Spinicaudata.This faunistic diversity may result from abiotic features (the location of the ponds at the boundary of two climatic areas) and from a heterogeneous geological substratum, creating a patchwork of temporary ponds with various mesologic conditions. Secondarily, this diversity may result from different life history characteristics of each coexisting species. As all species hatch synchronically, coexistence is only possible if their growth rates and life span are different. This implies that horizontal and vertical distribution, and exploitation of food supplies in the habitat differ for each ecophase of the syntopic species (spatial and trophic exclusion). 1 4oJ J j : j J J 3oJ J J J j : J J 2oJ j J J j j J 1oJ J J

“…A similar situation (Margalef 1947;Alonso 1980) and in the spinicaudatan Leptestheriella madur~iensis (Royan 1976). From an experimental study, Mertens et al (1990) showed that Streptocephatus prosbocideus did not capture entomostraca offered and that fragments of crustaceans found in the gut content were ingested as cast exuviae.…”

Feeding ecology ofBranchinecta gaini (Crustacea: Anostraca) in ponds of South Shetland Islands, Antarctica

The feeding habits and food selectivity of Branchinecta gaini were studied in six ponds on an Antarctic island. B. gaini behaves as a detritovorous, herbivorous filter-feeder, feeding largely on organic sediments and bottom communities. The bulk of the gut contents were formed from amorphous organic material presumably of vegetal origin, and a great variety of organisms from algae to remains of larval stages of Diptera. Filamentous algae were negatively selected but hyphae and spores, as well as remains of B. gaini, were positively selected.
