متن کاملChromosomal variation in Argentine populations of Akodon montensis Thomas, 1913 (Rodentia, Cricetidae, Sigmodontinae)
The genus Akodon Meyen, 1833 is one of the most species-rich among sigmodontine rodents and has great chromosome variability. Akodon montensis has a relatively broad distribution in South America, and Argentine populations are located in the southernmost region of its range. Brazilian populations have important chromosomal variability, but cytogenetic data from Argentina are scarce. We performe...
متن کاملAdditional data on the synlophe of Stilestrongylus aculeata (Travassos, 1918) and Stilestrongylus eta (Travassos, 1937) (Heligmonellidae) parasitic in Akodon montensis (Sigmodontinae) from the Atlantic Forest.
Additional data on the synlophe and morphological measurements are provided for the heligmonellids Stilestrongylus aculeata (Travassos, 1918) and Stilestrongylus eta (Travassos, 1937), collected from Akodon montensis Thomas, 1913, of the Atlantic Forest, Rio de Janeiro, Brazil. The synlophe of S. aculeata is characterized by 19 cuticular middle body ridges in males and 24 cuticular middle body ...
متن کاملCoral reef mesopredators switch prey, shortening food chains, in response to habitat degradation
Diet specificity is likely to be the key predictor of a predator's vulnerability to changing habitat and prey conditions. Understanding the degree to which predatory coral reef fishes adjust or maintain prey choice, in response to declines in coral cover and changes in prey availability, is critical for predicting how they may respond to reef habitat degradation. Here, we use stable isotope ana...
متن کاملReproduction, development and growth of Akodon lindberghi (Hershkovitz, 1990) (Rodentia, Muridae, Sigmodontinae) raised in captivity.
The reproduction, development and growth of Akodon lindberghi were studied in captivity. The colony was derived from animals captured in Simão Pereira, Minas Gerais state, which represents a new area of geographical distribution known for this species. Twelve males and twelve females were crossed, producing 144 young in 53 litters. Post-partum oestrus was observed and gestation length was estim...
