Food Habits of Young-of-the-Year Fishes in Abbey Pond, South Dakota
… Chydorus sp. was positively elected and that Bosmina longirostris and Ceriodaphnia sp. were negatively elected. Entomostracans were the dominant food organisms for young black crappie throughout their first summer of life. Young black crappie exhibited positive electivity indices for cyclopoid …

Predatory Impact of Exotic Cladoceran Cercopagis pengoi on the Zooplankton of Lake Ontario
… post-invasion abundances of Daphnia retrocurva, Bosmina longirostris and Diacyclops thomasi suggests that Cercopagis is having a major effect on zooplankton abundance in the lake. In the laboratory Cercopagis fed on a number of zooplankton including the rotifer Asplanchna priodonta and the …

Feeding of Naupliar and Adult Carnivorous Cyclopoids (Crustacea : Copepoda)
… Adult cyclopoids predated on cyclopoid nauplii, "Bosmina", "Asplanchna", and "Paramecium", but not on "Ceriodaphnia", ostracods, "Selenastrum", nor bacteria. One-day old nauplii fed on bacteria mixed with diatomaceous earth and dissolved organics, but not on "Ceriodaphnia", "Bosmina", …

Paleo-Ecotoxicology of Yellowknife (Northwest Territories, Canada) Lakes Impacted by Historic Gold Mining Activities
… of the most contaminated lakes, while pelagic Bosmina were dominant in lakes with low arsenic. No viable Daphnia resting eggs were found in Pocket Lake, indicating that future resurrection ecology studies from Daphnia populations are not feasible. My research provides new information on the …

Food Habits of Fish In A Multispecies Farm Pond
… Daphnia galeata was positively selected while Bosmina longirostris and both cyclopoid and calanoid copepods were selected against by all three species of fish. With the exception of Daphnia parvula, which was positively selected by adult black crappies, the smaller cladocerans were generally …

Morphological antipredator adaptations in water fleas
Some Bosmina and Daphnia species have the ability to develop extreme morphological antipredator defences, such as long antennules, high carapaces and helmets. The relative sizes of these plastic traits may differ substantially between populations, and also between individuals within a population, …

Food Selectivity of Bigmouth Buffalo (Ictiobus cyprinellus, Valenciennes) in Lake Poinsett, South Dakota
… galeata mendotae, Daphnia pulex juveniles, Bosmina longirostris, Chydorus sphaericus, and cyclopoid copepods) appeared to be taken when available; without selection. Selectivity appeared to be dependent on the morphology of the gill rakers for all organisms except calanoid copepods which …

Reproduction and early life history of a landlocked population of alewife (Alosa pseudoharencus) in Claytor Lake, Virginia
… food item in diets of alewives 6 to 35 mm TL. Bosmina longirostris dominated diets of alewives 36 to 70 mm TL. Size-selective planktivority of larval alewives was equivalent to that of adults at sizes as small as 31 mm TL, and may have significantly contributed to observed changes of …

Verteilung und Ernährung larvaler und juveniler Stadien von Plötze (Rutilus rutilus (L.)) und Barsch (Perca fluviatilis L.) im Biomanipulationsexperiment Feldberger Haussee (Mecklenburg-Vorpommern)

The role of aquatic macrophytes in the availability of food for young fish
… and Ceriodaphnia pulchella and the open water by Bosmina longirostris and C. vernalis americanus. C. pulchella and B. longirostris seemed mutually exclusive . Evidence from a second gravel-pit lake (lower fish stock) indicated that this was partly caused by fish predation pressure in the first …

Biotic Impacts in Shallow Water Bodies of South Dakota Resulting From Common Carp Invasion
… genera, with the possible exception of Bosmina spp. Body lengths of Daphnia spp. also did not differ. Submergent macrophyte coverages were compared during August 2012, and systems without carp had significantly greater coverages. The disparity in submergent macrophytes may explain …

Alkyl Polyglucoside Compound Influences Freshwater Plankton Community Structure in Floating Mesocosms
… domination by small-bodied cladocerans (<em>Bosmina </em>sp.). Thus APG-induced decreases in DO availability, losses of autochthonous carbon production, and shifts from invertebrate predator (copepod) dominated communities to cladocerans has important implications for food availability and …

Strong Interactive Species in Metacommunities: The Interaction Between Dispersal and Daphnia magna in Zooplankton Communities
… for certain taxa resulting in the increase of Bosmina and Simocephalus while other taxa decreased, for example Streblocerus. This trend was likely due to the feeding and grazing habits of D. magna which is known to outcompete other large zooplankton for larger phytoplankton taxa. Lastly, D. …

Recruitment of Bluegill and Yellow Perch in Nebraska Sandhills Lakes: Integrating Multiple Life Stages
… regulation of recruitment. Copepod nauplii and Bosmina spp. were commonly used by bluegill and copepods were commonly used by yellow perch. There were abundant zooplankton populations available for consumption. Matches in larval bluegill and yellow perch abundance and zooplankton abundance were …

Effects of environmental warming on lentic freshwater communities and the behavioral and physiological responses by fishes to warming
… lessened in smaller zooplankton (i.e. rotifers, bosmina). Mesocosms showed that rotifers were increased due to warming, which may be a difference based on ecological scale. There were taxa-specific interactions between warming and the addition of fish in mesocosms, indicating that fish and …
