Angiostrongylus cantonensis, commonly known as the rat lungworm, is a metastrongyloid nematode found primarily not only in tropical and subtropical regions but also temperate areas considered leading cause of eosinophilic meningitis humans. Synanthropic rodents such Rattus norvegicus rattus are most frequent definitive hosts this parasite.
Within a species, home-range size can vary due to intrinsic and extrinsic factors. In this study we test the hypotheses that social group sizes (intrinsic) of capybaras (Hydrochoerus hydrochaeris) food availability in their habitat (extrinsic) affect sizes. We used minimum convex polygon method estimate core areas (the area which each was present during all seasons). Home-range estimates varied from 11.3 ha 27.6 ( ± 1.89 SE). Core accounted for mean 22.5% total size. Home ranges measured...
Geoffroy's cat (Leopardus geoffroyi), a small wild of South America, showed in the last years decline population abundance mainly related to both habitat destruction and hunting.The increasing human densities consequent demand for food natural resources will rapidly erode fragment its remaining habitats.In Argentina most studies about diet have been conducted protected areas or their surroundings, while there are no purely agricultural systems.We described composition Leopardus geoffroyi...
Mammal hairs differ among species and may therefore be used for diagnoses at the level. We characterized dorsal guard of most small rodent that found in central Buenos Aires province (Argentina), according to their geographic distribution: Cavia aperea, Rattus rattus, R. norvegicus, Mus musculus, Holochilus brasiliensis, Scapteromys aquaticus, Oxymycterus rufus, Oligoryzomys flavescens, Akodon azarae, Deltamys kempi, Calomys laucha C. musculinus. provide discriminant functions a dichotomic...
Abstract Biotic resistance has been invoked as a major barrier to woody species invasion, although the role of resident generalist consumers and their interaction with seed availability in local community received little attention. We assessed tree consumption by rodents under two different scenarios: (i) documented field spatio‐temporal patterns predation native on exotic species, G leditsia triacanthos or ‘honey locust’ R obinia pseudoacacia ‘white (family L eguminosae), five grassland...
We studied the small mammal assemblage (bats, marsupials and rodents) of Parque Nacional Chaco Capitán Solari (Chaco Province, Argentina) based on captures analysis owl pellets. Twenty-one species were recorded during a brief survey, including two marsupials, seven bats, twelve rodents. In addition, we documented first occurrence bat Lasiurus ega in extended to southwest distribution didelphid marsupial Cryptonanus chacoensis oryzomyine rodent Oecomys sp. also provided second site ents...

Abstract In urban rivers in many fast-growing cities, heavy metals pollution is one of the major quality issues. Quantifying its recovery success seems to be a difficult but necessary challenge, part, because complex database generally needed assess water quality. The overall goal this work was evaluate temporal changes metal concentrations polluted basin applying AEM method and determine physicochemical meteorological parameters associated with these using RDA. We analyzed 15 sites located...
