“…With growing interest in the conservation o f biodiversity in man-modified environments, effect o f edges in heterogeneous habitats has been the focus of several recent ecological studies (Jokimaki and Huhta 1996, Garcia et al 1998, Gardner 1998, Hansson 1998, Kuitunen et al 1998, Stevens and Husband 1998. Knowledge o f edge effects aid management authorities in planning timber harvest and wildlife conservation (Darveau et al 1997), in particular indicator species (Niemi et al 1997) such as the marten in northern Ontario (Watt et al 1996).…”

In order to clarify the relationship between American martens Martes americana (Turton, 1806), and roads in boreal forests, we tested the effect o f distance from road on marten habitat use by comparing the frequency of occurrence, and the number of, marten snow tracks in 27 pairs o f 300 and 400 m transect segments perpendicular to access roads, and corresponding segments 800 or 1000 m away from the road, for a total o f four spatial analyses. The number o f black spruce Picea mariana, stems was generally lower near roads (-94.0 < Ts < -63.0, p < 0.05), but otherwise forest composition generally did not differ significantly between road and forest segments. Depending on the spatial scale, 1 1 -1 4 road and 15 -18 forest (out of 27) segments had marten tracks, but the difference was not statistically significant (Fisher's exact test, p > 0.05). In all analyses, marten tracks were significantly fewer near roads (Wilcoxon test: -74 .0 < Ts < -62.0, p < 0.01) than away from roads. In segments with tracks, track density was significantly lower near roads than away from roads in three o f four spatial analyses (-3.3 < Ts < -2.9, p < 0.01). The findings suggest that snow track samples near roads can detect marten occurrence, but do not reflect the clumping pattern observed away from roads. Habitat selection studies using tracks should consider the possible effect o f roads on marten movement patterns.

Considering only surveys based on procedures comparable to those applied in the present study, species richness varied considerably, from nine at the Serra de Itabaiana National Park (Oliveira et al, 2005) and Morro Grande Forest Reserve to 36 at the EPDA-Peti reserve in Minas Gerais (Paglia et al, 2005).…”

“…Very few inventories are available for the northern half of the biome (Stevens and Husband, 1998;Oliveira et al, 2005;Percequillo et al, 2007;Silva and MendesPontes, 2008;Chagas et al, 2010;Feijó et al, 2016;Table 1), and one of the primary aims of the present study is to redress this imbalance, especially given the potential importance of regional variation in the composition of the mammalian fauna for the conservation and management of the biome (Beisiegel, 2010). The present study reports a survey of the mammal species of the Mata do Junco Wildlife Refuge, in the northeastern Brazilian state of Sergipe.…”

Home of several endemic species, the Brazilian Atlantic Forest has been reduced to about 11-16% of its original area, and is currently considered to be one of the hotspots of global conservation. In the northeastern Brazilian state of Sergipe, the 900-hectare Mata do Junco Wildlife Refuge was established in order to protect the regional fauna and flora. Mammals were surveyed in the Refuge on three days per month between June, 2011, and May, 2012, using a combination of sample methods. A total of 16 species representing 12 families were recorded, with the order Carnivora being the most common (seven species). Whereas three didelphimorph species were trapped, only one exotic rodent -Rattus norvegicus -was captured. Comparisons with surveys from other Atlantic Forest sites indicate an intermediate species richness in Mata do Junco Wildlife Refuge and similar to that of other sites in the northern portion of the biome.

“…In Brazil, most of the available studies have involved the fauna of the Atlantic Forest or Cerrado. Stevens & Husband (1998) recorded increasing diversity as a function of the distance from the edge in the Atlantic forest. In the same ecosystem, Pardini (2004) found significantly richer small mammal community in edge habitats in comparison with the interior of mature forest and concluded that arboreal species are more affected by edge effects.…”

Edge effects and the impact of wildfires on populations of small non-volant mammals in the forest-savanna transition zone in Southern Amazonia

Abstract:The impact of fire and edge effects on the community of small non-volant mammals was investigated in transitional Amazon forest within a matrix of soybean plantations. The animals were live trapped on 24 line transects, of which 16 were distributed in unburned areas and 8 in a burned area. A total of 11 species was recorded, including six rodents and five marsupials. The abundance and richness of small mammals appeared to decrease in burned areas, although this impact appeared to mask edge effects. In the absence of fire impacts, a positive relationship was found between mammal abundance and the distance from the forest edge. The impact of the edge effect on the diversity of small mammals appears to be influenced by the type of anthropogenic matrix and the ecological characteristics of the different species.

Efeito de borda e do fogo sobre pequenos mamíferos não-voadores (Rodentia e Didelphimorphia) em uma zona de transição Floresta-Cerrado ao sul da Amazônia. Biota Neotrop. 12(3): http://www.biotaneotropica.org.br/v12n3/pt/abstract?article+bn00912032012Resumo: O efeito de borda e do fogo sobre a comunidade de pequenos mamíferos não-voadores foi investigada em uma área de transição entre Cerrado e Floresta em uma área de matriz de soja na Amazônia Oriental. Os indivíduos foram coletados em 24 transectos, dos quais 16 foram distribuídos em área sem efeito do fogo e oito distribuídos com efeito do fogo. Um total de 11 espécies foi registrado, incluindo seis roedores e cinco marsupiais. A espécie Hylaeamys megacephalus foi a mais abundante em áreas sem efeito do fogo. A abundância e riqueza de pequenos mamíferos não-voadores apresentaram uma diminuição em áreas queimadas, entretanto o efeito do fogo parece mascarar o efeito de borda nestas mesmas áreas. Em relação ao efeito de borda, sem nenhum efeito de fogo, a relação entre a abundância de pequenos mamíferos não-voadores com a distância da borda foi positiva. A relação entre a diversidade de pequenos mamíferos e efeito de borda pode ser ligada à vegetação matriz e características ecológicas de cada espécie.
