| a new genus and species of heligmonellidae (nematoda: trichostrongylina) parasitic in delomys dorsalis (rodentia: sigmodontinae) from misiones, argentina. | alippistrongylus bicaudatus gen. et sp. n. (nematoda: heligmonellidae) is described from the striped atlantic forest rat, delomys dorsalis (hensel) (rodentia: sigmodontinae), from the province of misiones in argentina. the new genus and species is characterised by a synlophe of 21 unequal ridges in both sexes without a gradient in size, with two ridges weakly sclerotised and oriented perpendicularly in the dorsal left quadrant; males with a highly dissymmetrical bursa with a hypertrophied right ... | 2014 | 25549502 |
| a new species of tunga (siphonaptera: tungidae) from brazil with a key to the adult species and neosomes. | tunga bossii new species of tungid sand flea belonging to the caecata group is described with illustrations of the adult female, parasitizing the wild rodent delomys dorsalis (hensel) from brazilian atlantic forest. tunga bossii differs from the ten other known species of tunginae by the size of the first segment of the maxillary palp and the presence of two bristles at the base of the maxilla. tunga bossii also can be differentiated from other species of the t. caecata group by the eye morpholo ... | 2012 | 22308767 |
| helminth metacommunity structure of wild rodents in a preserved area of the atlantic forest, southeast brazil. | the helminth fauna and metacommunity structure of eight sympatric sigmodontine rodents were investigated at the serra dos órgãos national park, an atlantic forest reserve located in the state of rio de janeiro, southeast brazil. rodents of the species abrawayaomys ruschii, akodon montensis, blarinomys breviceps , delomys dorsalis, oligoryzomys flavescens, oligoryzomys nigripes, oxymycterus quaestor and thaptomys nigrita were found infected with helminths. akodon montensis presented the highest t ... | 2019 | 30427522 |
| patterns of arboreal and terrestrial space use by non-volant small mammals in an araucaria forest of southern brazil. | despite the advances in the techniques for researching arboreal small mammals, detailed ecological data, such as habitat use patterns, are practically nonexistent for many species. using 150 live-traps installed on the ground, understory (1.0-5.0m) and canopy (>5.0m) we investigated patterns of arboreal and terrestrial space use by small mammals in an araucaria forest in southern brazil (29°29'08″s; 50°12'26″w). we also measured 19 microhabitat variables that could potentially influence the abun ... | 2014 | 30514009 |
