The diet of the Brazilian slender opossum (Marmosops paulensis) was determined through analysis fecal samples collected in an area montane Atlantic forest southeastern Brazil. M. paulensis consumed insects, arachnids, gastropods, fruits, flower parts, and small vertebrates. observed preference for Piper fruits could be related to spatiotemporal predictability this item, whereas Coleoptera, Blattodea, Opiliones due overestimation hard-bodied prey. Diet composition varied seasonally, with...
Data on the reproductive patterns of Brazilian slender opossum (Marmosops paulensis) were collected in an area Montane Atlantic forest, southeastern Brazil, from August 2002 to July 2004. Reproduction occurred September March both years, a period high food supply, probably as way maximize survival juveniles. There was nearly zero postmating survival, thus, no individual took part more than 1 breeding event. This pattern characterizes semelparous life history, which has been described other...
The 15 species of small carnivorous marsupials that comprise the genus Antechinus exhibit semelparity, a rare life-history strategy in mammals where synchronized death occurs after one breeding season. males, but not females, age rapidly (demonstrate organismal senescence) during season and show promise as new animal models ageing. Some antechinus are also threatened or endangered. Here, we report chromosome-level genome male yellow-footed flavipes. assembly has total length 3.2 Gb with...
In this study we describe and illustrate a new species, Chrysso intervales n. sp., based on males females collected in Parque Estadual Intervales, an area of Atlantic Forest the State São Paulo, Brazil. We present data habitat selection, web architecture, thread adhesiveness, diet, mortality due to fungi for both sympatric Helvibis longicauda. Both species build webs vegetation close river margins, but they were not found forest sites away from these shaded extremely humid corridors. The are...
The sequence of molar eruption, along with the timing replacement 3rd deciduous premolar by a permanent premolar, has been documented in several species family Didelphidae, and routinely used to establish age classes. We dental eruption patterns 3 neotropical marsupial genus Caluromys, which constitute one most basal groups within Didelphidae. examined 258 specimens Caluromys derbianus, 54 C. lanatus, 386 philander. These have pattern that is similar Marmosops, after 4th molar. However, we...
The relative importance of factors that influence the habitats animals select often varies with spatial scale. We evaluated hypotheses habitat selection by 2 sympatric slender opossums (Marmosops) is scale-dependent, and coexistence in gray opossum (Marmosops incanus) Brazilian (M. paulensis) enabled through differential use components or segregation vertical strata, both. At a mesohabitat scale both species selected areas dense understory, especially obstruction 0–0.5 m above ground. finer,...
The aim of this study was to evaluate the role environmental (dry versus wet season) and individual (sex, body mass reproductive status) factors in levels faecal cortisol metabolites (FGCs) Gracilinanus agilis samples as an index stress species; well its association with abundance Eimeria spp, indicator immunocompetence against parasites. Our found that FGCFGCs are a reliable adrenal activity G. agilis. We increase considerably by stressors like dry season. Moreover, observed positive...
Abstract Understanding the relative importance of exogenous and endogenous factors in natural population dynamics has been a central question ecology. However, until recently few studies used long-term data to assess driving small mammal abundance Neotropical savannas. We 9-year set, based on monthly captures, understand two scansorial mammals inhabiting Brazilian Cerrado: semelparous gracile mouse opossum (Gracilinanus agilis), iteroparous long-tailed climbing (Rhipidomys macrurus), most...
Abstract Maternal care in spiders varies from just the construction of a protective silken structure for eggs and selection safe site to place them, long period association between mother spiderlings. Such extended may involve active protection predators parasitoids, food regurgitation, production trophic even matriphagy. In this study, we describe maternal H elvibis longicauda ( T heridiidae) evaluate effectiveness against We conducted experiments comparing frequency egg sac destruction...
Abstract Habitat loss, fragmentation, and degradation of habitats are among the most pervasive impacts on species persistence. Mammals may vary in their response to these impacts, both abundance physiological parameters. Herein, we verified how habitat quality influenced small mammal nutritional status stress levels five semi‐deciduous forest remnants Brazilian Cerrado. To assess species' responses, used body condition as an indicator neutrophil/lymphocyte (N/L) ratio chronic Gracilinanus...
Spatial organization within animal populations is often thought to reflect the outcome of strategies implemented by each individual enhance its reproductive success and survival (Clutton-Brock 1989). Thus, while females usually focus on acquisition food breeding sites, male dispersion more determined distribution availability Due these factors, intraspecific competition for space could lead adoption a territorial strategy, whenever benefits defence are higher than costs (Brown & Orians...
SUMMARY The aggregation of parasites among hosts is associated with differential host exposure and susceptibility to parasites, which varies according gender, body size, reproductive status environmental factors. We evaluated the role these factors on infestation by Eimeria spp. (Eimeriidae) in agile gracile mouse opossum ( Gracilinanus agilis ), a semelparous didelphid inhabiting neotropical savannahs. abundance prevalence G. were breeding individuals lesser extent climatic season, both...
Abstract Space use patterns of a population are result the set movements its individuals, which directly influenced by their attributes and environmental conditions. Understanding space determinants may give us insights about species’ ecology, social mating systems. Although echimyid rodents display variety systems, burrowing species poorly studied due to cryptic habits. Hence, in this study, we evaluated effects body mass, sex, palm fruit availability on Clyomys laticeps , measuring daily...
Choosing a period to perform basic survival and breeding activities follows trade-off between the costs benefits associated environmental biotic demands, in which individuals try maximize their fitness. Once rodents have small tolerance high temperatures, activity patterns are usually thermally constrained. No information is registered about of semi-fossorial spiny rat Clyomys laticeps, inhabits open physiognomies savannah formations, hence dealing with large daily variations temperature...
Abstract Soil disturbances promoted by the construction of subterranean systems are a classic example ecosystem engineering. The broad‐headed spiny rat Clyomys laticeps caches seeds in excavated and occupied its individuals, thus acting as potential engineers Brazilian savannah. However, effects their activities on soil nutrient content animal communities still unknown. Here, we assessed role C. an allogenic engineer shrub savannah site. Our results demonstrated that systems, which contain...
Our aim was to survey the non-flying small mammals inhabiting an Atlantic forest area situated nearby a limestone quarry (Limeira quarry), located at Ribeirão Grande municipality (SP), southeastern Brazil. Species were captured with pitfall and Sherman traps along eight pairs of 60 m transects distributed four different distances from (60, 220, 740 1300 m).
