Fire is a major form of disturbance in terrestrial ecosystems, mainly tropical savannas. In these the effects large wildfires are potentially high on small and relatively less mobile animals, like mammals. We investigated an extensive wildfire (≈ 6,240 ha) September 2011 populations 2 arboreal-scansorial mammals—the gracile mouse opossum, Gracilinanus agilis, long-tailed climbing mouse, Rhipidomys macrurus—in 4 savanna woodland patches (1 burned, 3 unburned) highly threatened Brazilian...
Abstract Seasonality is a prevalent environmental feature in tropical forests and can shape the life history of organisms subjected to regular periodic changes temperature rainfall. Tropical forest marsupials usually reproduce seasonally response limited productive periods. This seasonality reproduction may have an impact on other vital rates contribute differently population growth rate (λ) different seasons. Here, we employed matrix model elasticity analysis assess potential contribution...
A major difficulty in the application of probabilistic models to estimations mammal abundance is obtaining a data set that meets all assumptions model. In this paper, we evaluated concordance correlation among three population size estimators, minimum number alive (MNA), jackknife and model suggested by selection algorithm CAPTURE (the best-fit model), using long-term on Brazilian small species obtained from different studies. The coefficients between estimates indicated enumeration...
The Amazon comprises many of the largest rivers in planet and also houses some richest bat communities world. Rivers are important geographic barriers for dispersal distribution different taxa worldwide and, particularly region, they form conceptual empirical bases recognition so-called Areas Endemism terrestrial vertebrates. Despite vast literature on role vertebrate community structure Forest, this process has never been investigated using a comprehensive dataset Neotropical region. In...
Abstract Fragmented habitats generally harbour small populations that are potentially more prone to local extinctions caused by biotic factors such as parasites. We evaluated the effects of botflies ( Cuterebra apicalis ) on naturally fragmented gracile mouse opossum Gracilinanus agilis ). examined how sex, food supplementation experiment, season and daily climatic variables affected body condition haemoglobin concentration in animals were parasitized or not botflies. Although parasitism did...
Em estudos ecológicos, a estação reprodutiva dos marsupiais neotropicais é frequentemente definida com base apenas na presença de filhotes no marsúpio e fêmeas lactantes, sem considerar as fases do ciclo estral, fecundação gestação. Considerando que lactação inibe o estral das fêmeas, relacionam padrões ecológicos se estão receptivas ao acasalamento podem resultar em interpretações equivocadas. Os objetivos deste estudo foram (1) determinar duração período qual Philander quica...
Rivers can be difficult barriers for animals to cross, especially that cannot swim or fly. The Amazon region has many of the largest rivers in world, which limits movements cross them. Thus, some animal species occur on one side a river but not other side. Isolation caused by physical generate what are called centers endemism, regions have unique seen anywhere else. In this article, we will explain how create movement and endemism contribute fascinating biodiversity region.
Abstract We describe a newly developed and low-cost feeder designed for use with arboreal small mammals under any climatic condition. As part of project on bottom-up regulation mammal populations in central Brazil, we present the results 16 months food supplementation. During study, more than 118 kg milled cat were consumed, out total 207 offered. Moreover, registered low rate loss (14.05%) feeders from falling to ground or termite/ant colonization. The round-pot described here represents...
Semelparity, the life-history strategy characterized by death after first reproduction, is restricted in mammals to only two marsupial families, Dasyuridae Australasia and Didelphidae Neotropics. Among didelphids, studies suggest a semelparous pattern for mouse opossums of genus Marmosops. These have revealed that both sexes may low survival rates reproduction distinct Atlantic Forest populations. However, strategy, which usually considered speciesspecific trait, can also be found some...
Agonistic events can cause the death of one or more individuals involved and be an important factor in population structure. The recording these interactions between small mammals situ is a difficult task. Here, we describe for first time two intraspecific killing occurred inside traps male sigmodontine rodents belonging to species Oligoryzomys nigripes Oecomys cf. cleberi Neotropical savanna (Cerrado). We discuss on nature aggression males by examining location injuries. Our results provide...
The Brazilian Squirrel Guerlinguetus brasiliensis ingrami (Rodentia, Sciuridae) is commonly observed in the wild, yet its population parameters are poorly known because this species rarely captured with traditional live-traps. Here we evaluated of G. b. a 3-year capture-mark-recapture study at Serra da Bocaina National Park, Rio de Janeiro state, Brazil. Population were using Jolly-Seber model POPAN and Minimum Number Known to be Alive (MNKA). size estimates ranged between 3.2 ± 2.4 (mean...
