    A 14,000-year-old genome sheds light on the evolution and extinction of a Pleistocene vulture

    The New World Vulture [Coragyps] occidentalis (L. Miller, 1909) is one of many species that were extinct by the end of the Pleistocene. To understand its evolutionary history we sequenced the genome of a 14,000 y...

    Between-year variations in the development of crustacean zooplankton in the Norwegian subalpine lake, Øvre Heimdalsvatn

    Data from the International Biological Programme (IBP) and subsequent studies have been re-analysed to test the two hypotheses which previously have been suggested concerning the zooplankton in the mountain la...

    Diel Vertical Migration of zooplankton in a eutrophic bay of Lake Victoria

    We studied the Diel Vertical Migration (DVM) of several zooplankton taxa and an important zooplanktivore Rastrineobola argentea in a eutrophic bay of Lake Victoria for a total of 3 months during wet and dry seaso...

    Ideal free distribution in Daphnia? Are daphnids able to consider both the food patch quality and the position of competitors?

    The distribution of the planktonic crustacean Daphnia pulex was tested in a ring-formedflow-through chamber divided into eleven sections. Thedistribution of the animals under both homogeneousfood conditions an...

    The future of cladoceran research

    The cladocerans are a group of Crustacea used as model organisms in many fields of biology. In system-atics, ecology, physiology and genetics, the cladocerans appear as frequently used examples in case studies...

    Interactions between Nile tilapia (Oreochromis niloticus) and cladocerans in ponds (Khartoum, Sudan)

    Juvenile Nile tilapia (Oreochromis niloticus) are omnivorous, and the question asked in this study is how they affect on their environment? Do they mainly act as predators on the cladoceran zooplankton or do they...

    Intraspecific variability in response to stimuli for male and ephippia formation in Daphnia pulex

    Natural clones and clones from laboratory crossings of Daphnia pulex have been tested in their response to stimuli for male and ephippia formation. The clones are from ponds in Illinois, USA, an area with both ob...
