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...
متن کاملInsights into the Evolutionary History of an Extinct South American Freshwater Snail Based on Historical DNA
Highly oxygenated freshwater habitats in the High Paraná River (Argentina-Paraguay) were home to highly endemic snails of the genus Aylacostoma, which face extinction owing to the impoundment of the Yacyretá Reservoir in the 1990s. Two species, A. chloroticum and A. brunneum, are currently included in an ongoing ex situ conservation programme, whereas A. guaraniticum and A. stigmaticum are pres...
متن کاملNew oxyuroid nematodes of the genera Ichthyouris and Spinoxyuris from South American freshwater fishes.
Three hitherto unknown oxyuroid nematode species of the family Pharyngodonidae are described from the intestine of South American freshwater fishes, two of them being established as species new to science: Spinoxyuris annulata sp. n. from Myleus ternetzi (Norman) (Serrasalmidae) from French Guiana (Sinnamary River) and Ichthyouris ovifilamentosa sp. n. from Cichlasoma sp. (Cichlidae) from Amazo...
متن کاملDiversification and Species Boundaries of Rhinebothrium (Cestoda; Rhinebothriidea) in South American Freshwater Stingrays (Batoidea; Potamotrygonidae)
BACKGROUND Neotropical freshwater stingrays (Batoidea: Potamotrygonidae) host a diverse parasite fauna, including cestodes. Both cestodes and their stingray hosts are marine-derived, but the taxonomy of this host/parasite system is poorly understood. METHODOLOGY Morphological and molecular (Cytochrome oxidase I) data were used to investigate diversity in freshwater lineages of the cestode gen...
متن کاملMyxobolus absonus sp. n. (Myxozoa: Myxosporea) parasitizing pimelodus maculatus (siluriformes: Pimelodidae), a South American freshwater fish.
A new myxoporean species is described from a freshwater fish in Brazil. Myxobolus absonus sp. n. was found infecting Pimelodus maculatus captured in the river Piracicaba, State of São Paulo, Brazil. Cysts were found free in the opercular cavity. The spores are large (length--15.7 +/- 1.5 microns, width--10.2 +/- 0.7 microns; mean +/- S.D.) and oval in shape, with the anterior end slightly point...
