Myxidium biliare sp. n. (Myxozoa) from gall bladder of Galaxias maculatus (Osmeriformes: Galaxiidae) in Patagonia (Argentina).
Myxidium biliare sp. n., a new myxosporean species parasitizing the gall bladder of Galaxias maculatus (Jenyns), in Patagonia, is described. Its coelozoic plasmodia were floating free in the bile. Spores are fusiform 13.7 +/- 0.9 microm long and 6.9 +/- 0.6 microm wide, with rounded ends in frontal view and slightly pointed ends in sutural view; shell with ridges and sinuous sutural line. Both ...
متن کاملIsolation Driven Divergence in Osmoregulation in Galaxias maculatus (Jenyns, 1848) (Actinopterygii: Osmeriformes)
BACKGROUND Marine species have colonized extreme environments during evolution such as freshwater habitats. The amphidromous teleost fish, Galaxias maculatus is found mainly migrating between estuaries and rivers, but some landlocked populations have been described in lakes formed during the last deglaciation process in the Andes. In the present study we use mtDNA sequences to reconstruct the h...
متن کاملTen novel microsatellite loci characterized for a remarkably widespread fish: Galaxias maculatus (Galaxiidae).
Ten polymorphic microsatellite markers (five tetra-, one compound tetra-, one octa- and three dinucleotides) were isolated and characterized for Galaxias maculatus, a fish species widely distributed in the Southern Hemisphere. Markers were tested in 89 individual samples from a single location and the number of alleles ranged between 2 and 28. Observed and expected heterozygosities ranged from ...
متن کاملAbsence of Tylodelphys barilochensis (Trematoda: Diplostomidae): induced mortality in "puyenes" Galaxias maculatus (Teleostomi: Galaxiidae) from Southern Argentina.
The “puyen”, Galaxias maculatus, is a small, autochthonous fish (no longer than 10 cm in this region). This species is protected in the Nahuel Huapi National Park and Reserve. Information on its biology is available in RM McDowall (1968 Fish Res Bull 2: 1-84, 1972 J R Soc New Zel 2: 325-367), DA Pollard (1971 Aus J Mar Fresh Res 22: 91-123) and RA Ferriz (1987 Rev Mus Arg B Riv 5: 29-38). Tylod...
متن کاملAilinella mirabilis gen. n., sp. n. (eucestoda: pseudophyllidea) from Galaxias maculatus (Pisces: Galaxiidae) in the Andean-Patagonian region of Argentina.
Ailinella gen. n. (Pseudophyllidea: Triaenophoridae) is proposed to accommodate Ailinella mirabilis sp. n. from Galaxias maculatus (Jenyns, 1842), a freshwater fish inhabiting the Andean lakes in Argentinean Patagonia. Ailinella belongs to the Triaenophoridae because it has a marginal genital pore, a follicular vitelline gland, and a ventral uterine pore. The new genus can be distinguished from...
