“…The cladoceran Bosmina and the calanoid copepods were essentially encountered in seston, whereas the cladocerans Chydorus and more particularly Scapholeberis were the dominant species in neuston. Morphological characteristics of Scapholeberis, with its modified ventral rim of valves, allow the animals to hang upside down at the underside of the surface film of the water (Dumont and Pensaert 1983). In addition, their high melanin pigment content protects them against high ultraviolet radiation at the water-air interface (Kerfoot 1982).…”

Huge amounts of pollen can accumulate at the air-water interface during the floral bloom of wind-pollinated trees. We hypothesized that such pollen rains act as subsidy pulses, promoting the development of a neustonic microbial food web and the transfer of pollen organic carbon to aquatic consumers. During a pine pollen rain event on an oxbow lake, microorganism concentrations were by far higher in the neuston, where pollen grains accumulated, than in the seston. Zooplankton species were also unevenly distributed in the two compartments. Bulk isotope and isotopes of fatty acid analyses revealed trophic partitioning among these zooplankton species, with some of the taxa foraging specifically on neuston, where they benefit from pollen-derived carbon. Microorganisms were identified as a key element in the trophic upgrading of pollen food quality and in the transfer of pollen carbon to metazoan consumers. Pollen rains may thus contribute, as an allochthonous food pulse, to aquatic production at specific seasons, but they may also act as a structuring factor in lake habitats.

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 .

“…Rotifer identification was based on Koste (1978), Segers (1995), De Smet (1996) and Nogrady and Segers (2002). Crustaceans, with the exception of juvenile copepods, were identified to the level of genus or species based on Ringuelet (1958), Olivier (1962), Paggi (1978Paggi ( , 1994, Dumont and Pensaert (1983), Reid (1985), Bayly (1992), Smirnov (1996), Sinev (2001Sinev ( , 2004, Benzi (2005) among others.…”

Knowledge of regional factors influencing zooplankton structure in a semiarid river must include both the main channel and any tributaries in order to identify spatial and temporal patterns along with the main factor that affect the zooplankton community. Accordingly, seasonal samples were taken during 1997-1999 at 15 stations in the Salado River basin, where 172 species were identified (53 protozoans, 88 rotifers and 31 crustaceans). Conductivity and temperature optima and tolerances were calculated for the evident taxa. Different assemblages were recognized by cluster analysis, on the basis of their temperature and conductivity preferences. With respect to the zooplankton assemblages, three zones can be distinguished along the longitudinal axis of the basin: (1) the headwaters (the effluent from large saline shallow lakes), (2) the inter-tributaries, and (3) the lower basin and associated shallow lakes. The spatial distribution of the assemblages was a result of the combined action of factors always promoting the dominance of rotifers. The influence of floodplain waters (backwater ponds, waterlogged depressions, flushing lakes) was attenuated progressively downstream, thus producing disadvantages for the crustaceans. The food availability and high nutrient concentrations related to land use in the headwaters favoured the co-dominance of cladocerans and copepods along with the rotifers in that region.
