ABREU, M.S.L.; SCHMITZ, G.W.; OLIVEIRA, L.R. 2015. Recursos alimentares nos estratos verticais e sua relação com pequenos mamíferos em uma Floresta de Araucária do sul do Brasil. Revista de Ciências Ambientais 9(2):131-144. doi: 10.18316/1981-8858.16
Abstract. Food resources on the vertical strata and their relationship with small mammals in an Araucaria forest of southern Brazil. This study presents the relationship between the use of different layers by non-volant small mammals and the food resources availability in an Araucaria Forest area from southern Brazil. In this sense, 150 live traps were placed on the ground, understory and canopy. The availability of resources in the layers was evaluated by counting fruits, seeds and captured invertebrates. As a result, 10 species were recorded of non-volant small mammals. An inverse relationship was found between captures of: Akodon montensis and availability of fruits and seeds on the ground (R = -0.95, P = 0.05); Juliomys sp. and invertebrates abundance in the canopy (R = -0.96, P = 0.04); and Gracilinanus microtarsus and total food availability in the canopy (R = -0.99, P = 0.008). The results suggest that in times of food scarcity, small mammals in the Araucaria Forest may need more time searching for food, increasing catch rates in the strata where they live.

Seed survival and dispersal of an endemic Atlantic forest palm: the combined effects of defaunation and forest fragmentation
GALETTI, M. DONATTI, C.I.; PIRES, A.S.; GUIMARÃES JR., P.R.; JORDANO, P. 2006. Seed survival and dispersal of an endemic Atlantic forest palm: the combined effects of defaunation and forest fragmentation. Botanical Journal of the Linnean Society 151:141-149.
Abstract. About 45 palm species occur in the Atlantic forest of Brazil, and most of them are affected by loss of seed dispersers resulting from forest fragmentation and hunting. Here we report the effects of habitat loss and defaunation on the seed dispersal system of an endemic palm, Astrocaryum aculeatissimum. We evaluated seed removal, insect and rodent seed predation, and scatter-hoarding in nine sites, ranging from 19 ha to 79 000 ha. We report the seedling, juvenile and adult palm densities in this range of sites. Endocarps remaining beneath the parent palm had a higher probability of being preyed upon by insects in small, mostly fragmented and more defaunated sites. The frequency of successful seed removal, scatter-hoarding and consumption by rodents increased in the larger, less defaunated sites. Successful removal and dispersal collapsed in small (< 1000 ha), highly defaunated sites and frequently resulted in low densities of both seedlings and juveniles. Our results indicate that a large fraction of Atlantic forest palms that rely on scatter-hoarding rodents may become regionally extinct due to forest fragmentation and defaunation. Current management practices including palm extraction and hunting pressure have a lasting effect on Atlantic forest palm regeneration by severely limiting successful recruitment of prereproductive individuals.

Seed predation by rodents and safe sites for large-seeded trees in a fragment of the Brazilian Atlantic forest
PINTO, S.R.R.; SANTOS, A.M.M.; TABARELLI, M. 2009. Seed predation by rodents and safe sites for large-seeded trees in a fragment of the Brazilian Atlantic forest. Brazilian Journal of Biology 69(3):763-771.
Abstract. Seed predation by small rodents is an emerging theme in the ecology of modified landscapes. Here we investigate the role played by the small rodent Oryzomys oniscus as a seed predator of large-seeded trees in a large remnant of the Atlantic forest - the Coimbra forest (3,500 ha), Alagoas state, northeastern Brazil. O. oniscus was captured and identified by setting twenty 500 m long transects, each one composed of 25 traps 20 m apart. This procedure resulted in 483 trap-nights set during a 20-mo period. We used 692 seeds (>15 mm length) from ten local large-seeded tree species for the seed predation trials that basically consisted of three treatments: one seed on the ground freely accessed by vertebrates (unprotected seed), one seed totally protected by an exclosure, and one partially-protected seed (exclosure just for medium-sized and large vertebrates). O. oniscus was captured throughout the Coimbra forest including forest edges (76 captures) and interior areas (67), and this small rodent was responsible for all seed predation visually documented inside exclosures. A 24 hours period of seed exposition permitted elevated rates of seed removal and predation. Seeds were much more removed/predated beneath fruiting trees, but rates varied according to the level of seed protection — 26.3% of predation among partially-protected versus 19.2% among unprotected seeds. Seeds suffered higher levels of seed predation/removal at the forest edge as well (up to 90%). In both habitats, most seeds (>84%) remained intact beneath trees without fruits, regardless of the level of seed protection. Our results suggest that O. oniscus may operate as an effective large-seed predator in forest fragments, in which adult trees without fruits constitute low resource spots and thereby provide, at least temporarily, safe sites for large seeds.

Amazonian freshwater habitats experiencing environmental and socieconomic threats affecting subsistence fisheries
ALHO, C.J.R.; REIS, R.E.; AQUINO, P.P.U. 2015. Amazonian freshwater habitats experiencing environmental and socieconomic threats affecting subsistence fisheries. AMBIO 44(5):412-425. doi: 10.1007/s13280-014-0610-z
Abstract. Matching the trend seen among the major large rivers of the globe, the Amazon River and its tributaries are facing aquatic ecosystem disruption that is affecting freshwater habitats and their associated biodiversity, including trends for decline in fishery resources. The Amazon’s aquatic ecosystems, linked natural resources, and human communities that depend on them are increasingly at risk from a number of identified threats, including expansion of agriculture; cattle pastures; infrastructure such as hydroelectric dams, logging, mining; and overfishing. The forest, which regulates the hydrological pulse, guaranteeing the distribution of rainfall and stabilizing seasonal flooding, has been affected by deforestation. Flooding dynamics of the Amazon Rivers are a major factor in regulating the intensity and timing of aquatic organisms. This study’s objective was to identify threats to the integrity of freshwater ecosystems, and to seek instruments for conservation and sustainable use, taking principally fish diversity and fisheries as factors for analysis.

Barn Owl pellets (Aves: Tyto furcata) reveal a higher mammalian richness in the Restinga de Jurubatiba National Park, Southeastern Brazil
LEMOS, H.M.; SILVA, C.A.O.; PATIU, F.M.; GONÇALVES, P.R. 2015. Barn Owl pellets (Aves: Tyto furcata) reveal a higher mammalian richness in the Restinga de Jurubatiba National Park, Southeastern Brazil. Biota Neotropica 15(2):1-9. http://dx.doi.org/10.1590/1676-06032015012114
Abstract. The northern coast of the state of Rio de Janeiro harbors the largest coastal sandy plains (restingas) of southeastern Brazil, severely threatened due to recent human occupation. In this context, mammal inventories becomes urgent to support biodiversity conservation and management policies. This paper aims to update the knowledge on the mammalian species richness of Restinga de Jurubatiba National Park by analyzing pellets of the Barn owl Tyto furcata. The analyses of 4745 mammalian bone fragments (1739 individuals) revealed the occurrence of 17 species belonging to the orders Rodentia (9 spp.), Didelphimorphia (2 spp.) and Chiroptera (6 spp.). The rodents Mus musculus and Cerradomys goytaca accounted for 77.2% of the total individuals preyed, suggesting that the Barn owl hunts in both disturbed and natural open shrub formations. A compilation of previous records, together with those provided in the present study, indicates the occurrence of 44 species of mammals in the Restinga de Jurubatiba National Park, of which six (13.6%) were exclusively detected in pellets. These new records include species adapted to open formations of the interior of Brazil that were not previously reported in restingas on the basis of voucher-specimens, such as the rodents Necromys lasiurus and Calomys tener, the latter being recorded for the first time in the littoral of Rio de Janeiro state. This study underscores the importance of owl pellet analysis as a complementary and indispensable method for inventorying mammals. The results highlight the Restinga de Jurubatiba National Park as one of the restingas in Southeastern Brazil with the highest number of mammal species.

Are otters generalists or do they prefer large, slower prey? Feeding flexibility of the Neotropical otter Lontra longicaudis in the Atlantic Forest
RHEINGANTZ, M.L.; OLIVEIRA-SANTOS, L.G.; WALDEMARIN, H.F.; CARAMASCHI, E.P. 2012. Are otters generalists or do they prefer large, slower prey? Feeding flexibility of the Neotropical otter Lontra longicaudis in the Atlantic Forest. IUCN Otter Specialist Group Bulletin 29(2):80-94.
Abstract. Despite there being several studies focusing on feeding habits of Lontra longicaudis, few studies aimed to evaluate its prey selectivity and none of them considered prey mobility. In this study, we report both its feeding flexibility and specialist feeding behaviour between two parts of Mambucaba River, Southeastern Brazil. We observed that they fed mainly on fish, crabs and crayfish. We did not observe seasonality either in diet or prey community availability. However, using ANOVA, we found differences between stretches for diet composition and in the availability of prey. Monotonic Multi-Dimensional Scaling ordination showed that the otter diet in mangroves was dominated by Brachyura and the prey availability by Brachyura, Caridea, Ariidae, Mugilidae, Gerreidae, Centropomidae and Cichlidae, while the diet in the river stretch was dominated by Cichlidae, Caridea and Heptapteridae, and the prey availability by Characidae, Erythrinidae and Heptapteridae. According to Ivlev Electivity Index, along the river few preys were consumed according to their abundance, the majority being selected. Otters preferred slower prey, no matter their size. We observed variation in the level of preference of the same prey in different stretches, with flexibility in otter diet. Otter ate few preys according to their abundance, but showed specialist feeding behaviour, eating the slowest prey of the stretch.

Occurrence and mortality of Lasiurus ega (Chiroptera, Vespertilionidae) in monocultures of Pinus sp. in Rio Grande do Sul, southern Brazil
BARROS, M.A.S.; RUI, A.M. 2011. Occurrence and mortality of Lasiurus ega (Chiroptera, Vespertilionidae) in monocultures of Pinus sp. in Rio Grande do Sul, southern Brazil. Chiroptera Neotropical 17(2):997-1002.
Abstract. Lasiurus ega is a widespread, insectivorous bat, occurring in several types of natural and altered habitats. Individuals are solitary and roost among tree branches and leaves. The present work records the use of Pinus individuals as diurnal roosts by L. ega in monocultures, and discusses the possible impact of such behavior on bat’s population. The study area is located in a rural property dominated by grassy vegetation, monocultures and invasions of Pinus spp. near the city of Palmares do Sul, in the northern Coastal Plain of Rio Grande do Sul, Brazil. Adults and offspring of L. ega were observed roosting in monocultures of Pinus trees. Some individuals do not leave their tree roosts during the cutting process, and are killed by crushing or by the workers themselves. Bat presence in felled trees is frequent, according to reports by the workers, and may involve different species. This paper represents the first record of the use of Pinus sp. as roost by a bat species in a region where Pinus has been introduced, and the first record of Pinus sp. occupation by L. ega. The monoculture management and removal of individuals of Pinus sp. induce L. ega mortality, including the loss of pregnant and lactating females, and offsprings. Considering the current scarcity of knowledge, it is recommended that Pinus sp. plantations do not be cut during spring and summer, in order to avoid the mortality of L. ega individuals during the critical reproductive period.

Abstract. First documented record of Holochilus brasiliensis (Desmarest, 1819) and Calomys laucha (G. Fischer, 1814) in the state of Santa Catarina, south Brazil. Studies on the richness of small mammals in the Brazilian South Region are recent and point out the need for using varied methods. This way, this paper contributes to knowledge on the fauna of small sigmodontinae rodents in Santa Catarina, including Holochilus brasiliensis and Calomys laucha in the list of species with confirmed occurrence in this state. The records of H. brasiliensis refer to Laguna (n = 2) and Timbe do Sul (n = 1). In turn, C. laucha presents 23 records from Capinzal. The entire material is represented by skull fragments from owl pellets samples collected from nests and feeding perches of the Tyto alba.

On the presence of Holochilus brasiliensis (Desmarest, 1819) (Rodentia: Cricetidae: Sigmodontinae) in the late Pleistocene of southern Brazil
KERBER, L.; LOPES, R.P.; OLIVEIRA, E.V.; RIBEIRO, A.M.; PEREIRA, J. 2012. On the presence of Holochilus brasiliensis (Desmarest, 1819) (Rodentia: Cricetidae: Sigmodontinae) in the late Pleistocene of southern Brazil. GAEA, Journal of Geoscience 8(2):47-54. doi: 10.4013/gaea.2012.82.02.
Abstract. Fossil remains of the sigmodontine rodent Holochilus brasiliensis (Desmarest, 1819) from two geographic areas from the state of Rio Grande do Sul, southern Brazil are reviewed and described here. The specimens came from two localities: Quaraí River in the western region, which has yielded a dentary with an incisor and molars, and Chuí Creek in the eastern region, where a fragmented right dentary and a maxillary fragment with molars were collected. The presence of this taxon in the late Pleistocene of meridional Brazil suggests the existence of perennial water bodies.

The taxonomic history of the south and central american akodont rodent genera: Thalpomys, Deltamys, Thaptomys, Hypsimys, Bolomys, Chroeomys, Abrothrix, Scotinomys, Akodon (Chalcomys and Akodon), Microxus, Podoxymys, Lenoxus, Oxymycterus, Notiomys, and Blarinomys
TATE, G.H.H. 1932. The taxonomic history of the south and central american akodont rodent genera: Thalpomys, Deltamys, Thaptomys, Hypsimys, Bolomys, Chroeomys, Abrothrix, Scotinomys, Akodon (Chalcomys and Akodon), Microxus, Podoxymys, Lenoxus, Oxymycterus, Notiomys, and Blarinomys. American Museum Novitates 582:1:32.
Abstract. In this paper, the sixth of my series, I have continued the treatment given in earlier papers. Since neither the several new akodont genera proposed by Thomas not his "groups" of the subgenus Akodon (sensu stricto) appear to be sharply defined, geographic arrangement of the species has been particularly difficult and may prove unsatisfactory. Though wishing to preserve, as much as possible, the arrangement of genera made by Thomas (1916), I have felt that certain changes were desirable: Zygodontomys has been treated in my fifth paper, and the akodont genera are rearranged so as to include Scotinomys and the new genera Deltamys and Hypsimys and to place Akodon (Akodon) next to Microxus.

Bat inventory in a Caatinga area in Northeastern Brazil, with a new occurrence in the state of Paraíba
BELTRÃO, M.G.; ZEPPELINI, C.G.; FRACASSO, M.P.A.; LOPES, L.C.S. 2015. Bat inventory in a Caatinga area in Northeastern Brazil, with a new occurrence in the state of Paraíba. Neotropical Biology and Conservation 10(1):15-20. doi: 10.4013/nbc.2015.101.06
Abstract. The Caatinga is a semi-arid ecosystem with a long history of anthropic impacts and scientific negligence. Since bats are the second most diverse group of mammals and have wide ecological roles, a well-based comprehension of their diversity for an area is important for management and conservationist actions. The goal of this study is to provide a list of the bat species found in Private Reserve of Natural Heritage Fazenda Almas, Paraíba, Northeastern Brazil. By sampling with mist nets and exploring roosts, we captured 126 specimens and recorded 19 species from 5 families. The most abundant species were Artibeus planirostris, Peropteryx macrotis, Myotis nigricans, and Carollia perspicillata. We registered high diversity of Phyllostominae, as well as the occurrence of the genus Histiotus in the state for the first time. Our results indicate that Caatinga areas can maintain bat assemblages with levels of diversity similar to moist tropical areas, which highlights the need to expand the network of protected areas in this threatened ecosystem.

Treetop shelter of a Neotropical River Otter cuba (Lontra longicaudis - Carnivora: Mustelidae) in an Amazonian flooded forest
SANTOS, P.M.R.S.; KINUPP, V.F.; COLETTO-SILVA, A. 2007. Treetop shelter of a Neotropical River Otter cuba (Lontra longicaudis - Carnivora: Mustelidae) in an Amazonian flooded forest. Acta Amazonica 37(2):309-312.
Abstract. The finding of a Neotropical river otter (Lontra longicaudis) cub occupying a shelter in a hollowed treetop is reported. The observation was made in a seasonally flooded forest in Central Amazonia, during the high water peak of the annual inundation cycle. A literature review indicates that this is the first description of a shelter of the species, both in a hollowed tree and in Amazonia. This observation can indicate a strong relationship between the species’ breeding cycle with the annual dynamics of Amazonian rivers. We discuss potential advantages and disadvantages of breeding when water level is high.

Diet of racoon Procyon cancrivorus (Carnivora, Procyonidae) in a mangrove and restinga area in Espirito Santo state, Brazil
MARTINELLI, M.M.; VOLPI, T.A. 2010. Diet of racoon Procyon cancrivorus (Carnivora, Procyonidae) in a mangrove and restinga area in Espirito Santo state, Brazil. Natureza on-line 8(3):150-151.
Abstract. Diet of Procyon cancrivorus was analised from fecal material. From 47 analyzed fecal samples, the most consumed items were Arthropods, found in 100% of scats, followed by Allagoptera arenaria (guriri-coconut), in 50.8% of scats, and small vertebrates and seeds, found in 4.3% of scats each. Among the arthropods, the most frequent crab family was the Ocypodidae, found in all samples.

Nota sobre convergência e divergência alimentar de canídeos e felídeos (Mammalia: Carnivora) simpátricos no Cerrado brasileiro
TROVATI, R.G.; CAMPOS, C.B.; BRITO, B.A. 2008. Nota sobre convergência e divergência alimentar de canídeos e felídeos (Mammalia: Carnivora) simpátricos no Cerrado brasileiro. Neotropical Biology and Conservation 3(2):95-100.
Abstract. Feed convergence and divergence of some sympatric canids and felids in Tocantins, Brazil were analyzed. Thirty-six fecal samples were collected. The results showed that 37.3% of the canids’ diet was made up of fruit and fibers (grasses e peel fruits) and 44% of the felids’ diet was made up of mammals. There were differences in the measurement and in the overlap of trophic niche, indicating canids as generalists and felids as specialists. Feeding of Phantera onca was more divergent and feeding of Puma yagouaroundi converged with the canids. Thus, the data collected shows that small felids have a similar diet to canids and only large and medium felids present divergence, but further studies are needed to better elucidate the degree of sympatric of these animals.

Incidental catch of South American sea lion in a pair trawl off southern Brazil
MACHADO, R.; OLIVEIRA, L.R.; MONTEALEGRE-QUIJANO, S. 2015. Incidental catch of South American sea lion in a pair trawl off southern Brazil. Neotropical Biology and Conservation 10(1):43-47. doi: 10.4013/nbc.2015.101.06
Abstract. The population of the South American sea lion, Otaria flavescens (Shaw, 1800), in Uruguay is declining at an annual rate of 1.6 to 2.0%. Although the reasons are still unknown, interactions with fishing activities have been identified as a major cause. The individuals that arrive along the coast of Brazil come from the breeding colonies off Uruguay after their breeding period. We report here the first record of incidental catch of South American sea lions in Brazilian waters by a pair trawl. On July 17th, 2008 a young male of South American sea lion was incidentally caught during a commercial pair trawl fishing trip along the southern Brazilian coast (32º57’S, 52º31’W), in a depth ranging from 15 to 20 m. Despite being punctual, this record is an evidence of a potential major threat to South American sea lions in southern Brazil and Uruguay, since trawl industrial fishing is a very important economic activity in South Brazil.

First record of the bushy-tailed opossum, Glironia venusta, Thomas, 1912, (Didelphimorphia) from Manaus, Amazonas, Brazil
CALZADA, J.; DELIBES, M.; KELLER, C.; PALOMARES, F.; MAGNUSSON, W. 2008. First record of the bushy-tailed opossum, Glironia venusta, Thomas, 1912, (Didelphimorphia) from Manaus, Amazonas, Brazil. Acta Amazonica 38(4):807-810.
Abstract. A new record of a very rarely observed mammal, the bushy-tailed opossum, Glironia venusta (Didelphimorphia), was obtained for the Adolpho Ducke Forest Reserve, Manaus, Amazonas state, Brazil. Only 17 other records existed of this species, most from the 1980s. There were only three previous records of the species from Brazil (in the states of Pará, Amazonas and Rondônia). This new record supports the notion that G. venusta is a locally rare species throughout its range, but widely distributed in Brazilian Amazonia.

Perceptions of human-carnivore conflicts in the High Andes of Argentina
LUCHERINI, M.; MERINO, M.J. 2008. Perceptions of human-carnivore conflicts in the High Andes of Argentina. Mountain Research and Development 28(1):81-85. DOI: http://dx.doi.org/10.1659/mrd.0903
Abstract. The Andean cat (Leopardus jacobitus), one of the world’s most threatened felids, forms part of the little known carnivore guild occurring in the dry areas of the High Andes. Although human–carnivore conflicts are among the major causes of carnivore population decline, no data are available on this issue for the High Andes. We report here the results of the first survey of human perceptions of, and attitudes towards, carnivores in the high-altitude Andes of Argentina. Interviews with 50 adults and 226 schoolchildren revealed that pumas (Puma concolor) and foxes (Lycalopex culpaeus) are considered pests for preying upon livestock and are actively hunted by adults. Although perceptions of the Andean cat and the Pampas cat (Leopardus colocolo) were more positive, especially among schoolchildren, they are also frequently killed by local people. We suggest that, contrary to what was previously thought, hunting might be affecting the conservation status of the Andean cat and of some puma populations in the High Andes of Argentina, and that education strategies may help to improve human attitudes, particularly in the case of the endangered Andean cat.

Niche separation between the maned wolf (Chrysocyon brachyurus), the crab-eating fox (Dusicyon thous) and the hoary fox (Dusicyon vetulus) in central Brazil
JÁCOMO, A.T.A.; SILVEIRA, L.; DINIZ-FILHO, J.A.F. 2004. Niche separation between the maned wolf (Chrysocyon brachyurus), the crab-eating fox (Dusicyon thous) and the hoary fox (Dusicyon vetulus) in central Brazil. Journal of Zoology, London 262:99-106. DOI:10.1017/S0952836903004473
Abstract. Four species of canids occur in the Cerrado of central Brazil. Three of them, the maned wolf Chrysocyon brachyurus, the crab-eating fox Dusicyon thous and the hoary fox Dusicyon vetulus, were studied in Emas National Park between 1996 and 1999 to investigate niche separation. The diet of the three species was studied to understand niche breadth and degree of overlap. Habitat and activity patterns were used as second and third ecological parameters to define niche dimensions, and were estimated using camera-trap data. The maned wolf is the largest species, weighing c. 21 kg, and is about three times larger than the crab-eating fox and six times larger than the hoary fox. The major ecological differences between the three species were found in their food niche and habitat use, where crab-eating fox presented higher differences from the hoary fox (Pianka’s index of niche overlap (O) = 0.405). Despite differences in niche breadth, habitat use between the hoary fox and the maned wolf were more similar, explaining their larger overlap, in comparison with habitat use by the crab-eating fox. Activity patterns among the species showed less divergence. The three species presented two activity peaks, one in the dusk–night period and another in the morning period. These data permit a better understanding of the ecological separation of the three Cerrado canids that enables their coexistence.

Medium and large-sized mammals of the Reserva Ecológica de Guapiaçú, Cachoeira de Macacu, RJ
CARVALHO, I.D.; OLIVEIRA, R.; PIRES, A.S. 2014. Medium and large-sized mammals of the Reserva Ecológica de Guapiaçú, Cachoeira de Macacu, RJ. Biota Neotropica 14(3):1-9.
Abstract: Medium and large-sized terrestrial mammals develop important functions in ecosystems maintenance. However, this group is the most vulnerable to local extinctions, through habitat loss or hunting. This study inventoried the community of medium and large mammals in the Reserva Ecológica de Guapiaçú (REGUA), Cachoeiras de Macacu, RJ, providing data on species composition, richness and abundance. Species were registered through the use of camera traps, sign survey and visual encounters on pre-existing trails and roads. The study was conducted from January to October 2012, with each month considered as a sample unit. An effort of 1568 cameras-day and 120 km traveled, resulted on 302 records of 22 species of medium and large-sized mammals, belonging to eight orders. This value corresponds to more than three-quarters of the richness described from this group in the Atlantic Forest of Rio de Janeiro state. Five species are under some level of regional, national or global threat. Three game species, Pecari tajacu, Cuniculus paca and Dasyprocta leporina were abundant in the area. The observed richness was comparable to that found in other studies conducted in rain forests. Thus, for its high number of species, including those under some degree of threat, we conclude that REGUA is an important area to mammal conservation, especially in the Atlantic Forest of Rio de Janeiro state.
Abstract: Medium and large-sized terrestrial mammals develop important functions in ecosystems maintenance. However, this group is the most vulnerable to local extinctions, through habitat loss or hunting. This study inventoried the community of medium and large mammals in the Reserva Ecológica de Guapiaçú (REGUA), Cachoeiras de Macacu, RJ, providing data on species composition, richness and abundance. Species were registered through the use of camera traps, sign survey and visual encounters on pre-existing trails and roads. The study was conducted from January to October 2012, with each month considered as a sample unit. An effort of 1568 cameras-day and 120 km traveled, resulted on 302 records of 22 species of medium and large-sized mammals, belonging to eight orders. This value corresponds to more than three-quarters of the richness described from this group in the Atlantic Forest of Rio de Janeiro state.

Abundance and community composition of small mammals in different habitats in Hugumburda forest, northern Ethiopia
ADAM, M.; WELEGERIMA, K.; MEHERETU, Y. 2015. Abundance and community composition of small mammals in different habitats in Hugumburda forest, northern Ethiopia. International Journal fo Biodiversity and Conservation 7(2):119-125. doi: 10.5897/IJBC2014.0787
Abstract. Tropical forest ecosystems harbor several species of small mammals. Diversity and abundance of small mammals in these forests reflect the quality and diversity of the ecosystems. The corrent study was carried out to assess abundance and species composition of small mammals (rodents and shrews) in three habitat types (Pterolobium, Juniperus and Cadia habitats) in Hugumburda forest, a dry afromontane forest in the Tigray region of North Ethiopia. The habitat types were selected based on the floristic compositions (plant species diversity) and level of human disturbance. All together, 179 individual small mammals belonging to seven rodent and one insectivore species were captured in 4,320 trap nights. The rodent species, with their relative abundance, were Stenocephalemys albipes, 55 (30.7%); Mastomys awashensis, 53 (29.6%); Arvicanthis dembeensis, 26 (14.5%); Lophuromys flavopunctatus, 22 (12.3%); Mus (Nannomys) setulosus, 14 (7.8%); Arvicanthis abysinicus 4 (2.2%); Dendromus mystacalis, 3 (1.7%) and the insectivore Crocidura olivieri, 2 (1.1%). There was significant variation in the small mammal abundance among the habitat types (X²= 29.45, P= 0.009), with more individuals caught in Pterolobium habitat, which has relatively highest plant species composition and lowest human disturbance than the other two habitats. The highest small mammal species diversity was also recorded in this habitat (H'= 1.76). Vegetation diversity and level of human interference are likely the major factors affecting small mammal abundance and composition in Hugumburda forest.

New records and description of the microstructural patterns of guard hair in Conepatus chinga (Molina, 1782) (Carnivora, Skunk) for the states of Paraná and Santa Catarina, southern Brazil
BAZILIO, S.; BASTIANI, E.; GOLEC, C. 2015. New records and description of the microstructural patterns of guard hair in Conepatus chinga (Molina, 1782) (Carnivora, Skunk) for the states of Paraná and Santa Catarina, southern Brazil. Biotemas 28(1):79-84. doi: http://dx.doi.org/10.5007/2175-7925.2015v28n1p79
Abstract. This article aims to show new records of Conepatus chinga for the states of Paraná and Santa Catarina, in southern Brazil, contributing to increase knowledge on its distribution, besides describing the microstructural patterns of its guard hair. Three run-over specimens were found in highway BR-280, two of them in the town of Palmas, in Paraná, and one in the town of Abelardo Luz, in Santa Catarina. For describing the cuticular and medullary pattern of guard hairs, sixty slides were made. Conepatus chinga has a cross-sectional and undulated cuticular pattern and an anisocytic medullary pattern. The description of microstructural patterns of C. chinga makes it easier to conduct studies related to its ecology, increasing the chances to identify hairs found in fecal samples from carnivores in mastofauna studies.
