In July and August 1988 samples of zooplankton were collected from 17 lakes on four islands. Five species of Cladocera, three species of Copepoda and 30 species of Rotifera were found. The maximum numbers of species in any ...

Islands biotas have played a significant part in evolutionary biology, because they are so often starkly different from continental biotas (even though it took Darwin some time to realize this; his visit to the Galapagos ...

Site similarities between areas of the Madeiran Archipelago were examined using data from collections of Coleoptera made over an eight year period. The similarities between the major island groups indicated that the Porto ...
