| Wild boar populations are rapidly spreading through midwest Brazil, causing crop damage, impacting biodiversity and, possibly, spreading diseases to livestock. Despite their threat, little is known about introduced populations in Brazilian agricultural landscapes. The critical lack of knowledge about basic aspects of wild boar spatial ecology led us to evaluate home range sizes, activity pattern and habitat selection in interface regions of agricultural crops and natural riparian forests. We captured and monitored seven individuals using global position system collars throughout 19 to 77 days. The home range sizes calculated by Minimum Convex Polygon and Biased Random Bridge Kernel ranged from 273 to 1253 ha (median = 497 ha) and from 129 to 779 ha (median... |

| Was investigated the home range size, habitat selection, as well as the spatial and activity overlap, of four mid-sized carnivore species in the Central Pantanal, Mato Grosso do Sul, Brazil. From December 2005 to September 2008, seven crab-eating foxes Cerdocyon thous, seven brown-nosed coatis Nasua nasua, and six ocelots Leopardus pardalis were radio-collared and monitored. Camera trap data on these species were also collected for the crab-eating raccoon Procyon cancrivorus. Was hypothesized that there would be large niche differentiation in preferred habitat-type or active period between generalist species with similar diet, and higher similarity in habitat-type or activity time between the generalist species (crab-eating foxes and coatis) and the more... |

| O gênero é Mazama possui dez espécies reconhecidas, sendo o mais diverso entre os cervídeos neotropicais. As características ecológicas deste grupo, adaptado para ambientes florestais fechados, constituem a principal razão pela qual a história natural do gênero é pouco estudada (Barrette, 1987). Como consequência dessa escassez, considera-se que 3 espécies do gênero possuam dados insuficientes, porém as outras cinco já estão enquadradas em alguma categoria de ameaça (IUCN, 2012). Na literatura, o total de animais do gênero monitorados por telemetria era de 15 indivíduos (13 M. gouazoubira e 2 M. americana), sendo 7 deles translocados (Ramos et al., 2010; Black-Décima et al., 2010). Nesse contexto, desenvolver metodologias para captura e obtenção de dados... |

| The giant otter (Pteronura brasiliensis) is listed as vulnerable in Brazil, is included in Appendix I of CITES and is classified as endangered by the IUCN. In Brazil, few viable populations persist outside the Amazon basin and the Pantanal wetland. Furthermore, there is limited information on the distribution and abundance of the existing populations. The aim of this study was to estimate the abundance of giant otters in the Pantanal wetland and to discuss the conservation status of this population. From July 2000 to November 2011 we conducted surveys throughout the Pantanal to detect the occurrence of giant otters by the observations of active dens and latrines and the direct visualization of the otters. We also monitored giant otter population in five... |

| The difficulty in observing and capturing elusive species in the wild is one of the main reasons for the limited number of studies on such species. This knowledge gap affects the development of conservation and management plans. Hence, testing the feasibility of research tools is essential for the future use and reliability of such tools. Camera traps increasingly are used as an alternative to capturing animals for wildlife research, and to generate important data for the management and conservation of many species. We identified individual free‐ranging gray brocket deer (Mazama gouazoubira) from the Brazilian Pantanal by their natural markings. From October 2011 through September 2012, we investigated the feasibility of using camera traps for... |

| ABSTRACT The black-headed night monkey, Aotus nigriceps, has one of the largest distribution ranges of the 11 night monkey species found across Central and South America. Yet, only three studies have focused on their ecology, describing considerable variation in habitat, group composition, and population density. Therefore, we analyzed habitat use, group composition, population density, and diet of 14 groups at two field sites in southeastern Peru. All sampled groups were found in secondary tropical rainforest, often dominated by native bamboo species. Half of the observed sleeping sites were in bamboo stands, though groups also emerged from cane thickets and lianas. This contrasts with other Aotus studies which have found groups living in tree cavities... |

| Na Reserva Florestal Walter Egler, localizada a 64 km de Manaus, no município de Rio Preto da Eva, foi investigada a ocorrência de Pteridófitas ao longo de uma toposseqüência. O grupo ocorre nos três ambientes observados na área (baixio, vertente e platô) com diferença tanto qualitativa quanto quantitativa. Foram registrados 375 indivíduos, distribuídos em oito famílias, 10 gêneros e 17 espécies; entre epífitas, hemiepífitas, herbáceas e arbóreas. Das 8 famílias, 4 ocorrem em todos os ambientes: Dennstaedtiaceae, Hymenophyllaceae, Dryopteridaceae e Lomariopsidaceae, enquanto, Cyatheaceae e Vittariaceae ocorrem apenas no baixio. Das 17 espécies encontradas, sete ocorrem apenas no baixio, três na vertente e cinco são comuns em todos os ambientes. |

| ABSTRACT Changes in environmental characteristics can affect habitat use by birds, impacting the number of individuals, number of species, and changing species composition and functional structure of assemblages. Metrics that evaluate the functional structure of biological assemblages constitute a complementary tool to the traditional taxonomic approach, because they quantify the differences between species by means of functional traits. We assessed the effect of environmental characteristics on the taxonomic diversity (species richness, species composition and number of individuals) and functional structure (functional richness, functional evenness, Rao’s functional diversity, and community-weighted mean traits) of bird assemblages in northern Mato Grosso... |

| Abstract The purpose of this study was to compare the alkaloid profile in different tissues analyzed by GC/MS and to contribute to the ecological knowledge of Calia secundiflora (patol). Samples of leaves, root and seeds of patol (mescal bean) were collected and field information was recorded in the States of Hidalgo and Querétaro, México, using the point-centered quarted method. Species dominance was calculated (value of importance) and the two locations were compared in species richness, similarity index, and soil data. Seventeen species of plants were found in Hidalgo and 21 in Querétaro; Flourensia resinosa and patol dominated the vegetation in Hidalgo, while patol and Dodonaea viscosa dominated in Querétaro. The profile of the quinolizidine alkaloids... |

| The present work investigated the occupation and the correlation of the shrimp abundance in relation to environmental variables in different habitats (mangroves, salt marshes and rocky outcrops) in an Amazon estuary. The collections were made in August and November 2009, at low syzygy tide on Areuá Beach, situated in the Extractive Reserve of Mãe Grande de Curuçá, Pará, Brazil totaling 20 pools. In each environment, we recorded the physical-chemical factors (pH, salinity, and temperature) and measured the area (m2) and volume (m3) of every pool through bathymetry. The average pH, salinity, temperature, area and volume of tide pools were 8.75 (± 0.8 standard deviation), 35.45 (± 3), 29.49 °C (± 2.32), 27.41 m2 (± 41.18), and 5.19 m3(± 8.01), respectively.... |

| ABSTRACT The aim of this study was to establish normal baseline ERG values of 23 anesthetized deer belonging to 8 neotropical species (Mazama americana, Mazama nemorivaga, Mazama gouazoubira, Mazama nana, Mazama bororo, Ozotocerus bezoarticus, Odocoileus virginianus and Blastocerus dichotomus). Only right eyes were studied. Chemical restraint was performed using xylazine associated with ketamine, IM, for M. americana, M. gouazoubira, M. nemorivaga, M. nana, M. bororo, O. bezoarticus and O. virginianus. A combination of tiletamine/zolazepam diluted in xylazine 2% was used for B. dichotomus individuals. After 20min of dark adaptation, electroretinograms were obtained using a handheld electroretinography (ERG) machine using the QuickRetCheck Protocol at three... |
