Geographical Distribution of Central American Freshwater Fishes

Historical biogeography of South American freshwater fishes

Dealing with complex palaeogeographical histories is a problem of major importance in biogeographical studies. Since the superposition of palaeogeographical events may produce multiple changes in species range distributions, highly complex patterns of animal and plant distributions are to be expected (Nelson & Platnick, 1981; Brown & Gibson, 1983; Myers & Institut de Recherche pour le Développe...

Identification and Determination of the Geographical Distribution of Freshwater Snails in Lorestan, Iran

Snails are creatures present in various ecosystems that, in addition to being present in human surroundings, some of them are also important in veterinary medicine and medicine as the intermediate hosts of Digenean trematodes. The present study was conducted to identify and determine the geographical distribution of freshwater snails and investigate the relationship of variables, such as season...

Distribution patterns of fishes in a freshwater deprived Eastern Cape estuary, with particular emphasis on the geographical headwater region

Small seine net fish assemblages in the headwater region of the Kariega Estuary are described and compared to the catch composition in other parts of the system. The geographical headwaters of the freshwater ‘deprived’ Kariega Estuary were utilised by a range of fish species but, in contrast to the nearby freshwater ‘rich’ Great Fish Estuary, few important angling species (e.g. spotted grunter ...

Speciation in Freshwater Fishes

The extraordinary species richness of teleost fishes has attracted much research on mechanisms and modes of speciation. We here review research on speciation in freshwater fish in light of speciation theory, and place this in a context of knowledge about broad-scale diversity patterns in freshwater fishes. We structure our review around the major axes of divergence during speciation in freshwat...
