Die Entomostraken der Danmark-Expedition

Studies on tropical freshwater zooplankton which commenced in the mid-19th century have been intensified during the past twenty years or so . The whole region, barring a few areas, has been investigated, including very recently tropical Australia . The widely scattered literature is briefly summarized with comments . Some general distributional patterns are emerging . There is a dearth of ecological studies especially on seasonality and production . Systematics lags behind the North Temperate zone in most tropical regions .

“…Juday (1915) reported on Cladocera from littoral samples of water in or near Mexico City . Copepods were reported from Yucatan by Wilson (1936) and from the Mexico City area by Brehm (1955). Lindberg (1954) analyzed samples of zooplankton for cyclopoid copepods from collections taken by fisheries biologists in various parts of Mexico .…”

Crustacean zooplankton species richness and associations in reservoirs and ponds of Aguascalientes State, Mexico

1996

We report the species of crustacean zooplankton found in 19 resevoirs and ponds that were sampled at on at least two occasions in Aguascalientes State, Mexico, at a latitude of about 21°30' North Latitude . We collected a total of 33 cladoceran taxa, 15 calanoid and cyclopoid copepods, an Ergasilus copepod, 2 anostracans, one notostracan species and an amphipod . All these taxa had previously been reported in Mexico . As in more temperate areas, there was a significant correlation between the species richness and lake size . The species-area relationship for Aguascalientes was indistinguishable from that of more northerly lakes . The two most common associations of zooplankton species were (1) those small species that occurred with fish : Daphnia parvula, Diaphanosoma birgei, Leptodiaptomus siciloides, Mastigodiaptomus albuquerquensis, and Thermocyclops inversus, and (2) the large Daphnia schodleri that occurred with the predator Notonecta, in the absence of fish . With minor variations, these two associations also occur throughout temperate North America .

“…Of these, Mastigodiaptomus montezumae Brehm, 1955 is common species in the centre of the country, but its original description lacks detail, and the type has been lost. It was described from a place called Potosi, apparently mine water disposal pond in the state of Hidalgo (Gerhard, 1986) ; however, it is not possible to ascertain the position of this site from the original paper.…”
