“…Desta maneira, a presença de corredores em paisagens fragmentadas leva ao aumento da abundância e riqueza destas espécies em pequenos fragmentos (Pardini et al 2005), contribuindo para a persistência destas populações no médio e longo prazo. No cerrado, as matas de galerias são fundamentais como abrigos para os pequenos mamíferos, pois funcionam como refúgios para as espécies durante as queimadas (Vieira & Marinho-Filho 1998). O mesmo ocorre em áreas incendiadas sazonalmente, como pastos e plantações de cana de açúcar, onde a mata ciliar é usada como abrigo e refúgio pelos mamíferos.…”

legislative changes and their impacts on mammal ecology and diversity in Brazil. Biota Neotrop. 10(4): http://www.biotaneotropica.org.br/v10n4/en/abstract?article+bn00710042010.Abstract: Forest ecosystems within Brazil host one of the highest levels of mammalian diversity on Earth, much of which within legally required forest set-asides in private landholdings. The Legal Reserves (RLs) and Permanent Protected Areas (APPs) of the Brazilian Forest Code provide an important strategy to maintain this diversity. Yet a proposed amendment to Brazil's 1965 forestry code would reduce protection of Brazil's forests, including the Amazon and the Atlantic forest, and bring irreversible detrimental effects to mammal diversity. Mammals are key components of forest ecosystem, providing important environmental services as pollinators, seed dispersers and ecosystem engineers. The local extinction of some species will negatively affect forest ecosystem service provisioning throughout the country. Another important effect of forest conversion within private properties, should the proposed changes happen, will be the emergence of new diseases, bringing serious public health problems in Brazil. Resumo: Os ecossistemas florestais do Brasil abrigam um dos mais altos níveis de diversidade de mamíferos da Terra, e boa parte dessa diversidade se encontra nas áreas legalmente protegidas em áreas de domínio privado. As reservas legais (RLs) e áreas de proteção permanente (APPs) representam estratégias importantes para a proteção e manutenção dessa diversidade. Mudanças propostas no Código Florestal certamente trarão efeitos irreversíveis para a diversidade de mamíferos no Brasil. Os mamíferos apresentam papéis-chave nos ecossistemas, atuando como polinizadores e dispersores de sementes. A extinção local de algumas espécies pode reduzir os serviços ecológicos nas RLs e APPs. Outra consequência grave da redução de áreas de vegetação nativa caso a mudança no Código Florestal seja aprovada será o aumento no risco de transmição de doenças, trazendo sério problemas a saúde pública no Brasil.

“…Studies in nontropical ecosystems, including deserts, grasslands, and temperate forests have recorded a decrease in the abundance of some species immediately after a wildfire (Quinn 1979, Fox 1982, Ojeda 1989, Fa and Sanchez-Cordero 1993, Churchfield 1997, Simon et al 2002, Converse et al 2006, reduced abundance in areas that are burned regularly (Sherburne-Junior 1959, Rana 1985 or the dominance of a few species in burned areas (Krefting & Ahlgren 1974, Kern 1981, Clark & Kaufman 1990. In most cases, the time elapsed since the disturbance seems to be an important variable determining the composition of the mammalian community (Vieira & Marinho-Filho 1998, Ford et al 1999, Simon et al 2002, Torre & Diáz 2004, Fisher & Wilkinson 2005. In the Cerrado, Briani et al (2004) and Vieira (1999) found that small mammals were relatively tolerant to such impacts, and were especially abundant during the early successional stages.…”

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.

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.

“…Fire is a frequent event in this vegetation mosaic, occurring approximately once every 2 years at the end of the dry season in August-October (Eiten 1972). Previous studies on the responses of small mammals to fire in the cerrado were conducted by Borchert and Hansen (1983), Gettinger and Ernest (1995), Vieira (1999), Vieira and Marinho-Filho (1998), Henriques et al (2000) and Briani et al (2004).…”

A simple graphical model of small mammal succession after fire in the Brazilian cerradoUn modè le graphique simple de repeuplement par les petits mammifè res du cerrado bré silen aprè s brû lis AbstractWe studied the succession of small mammal species after fire in the cerrado (Neotropical savanna) of Central Brazil. Populations of small mammals were sampled with live-trapping techniques in a series of nine sites of different successional age, ranging from 1 to 26 years after fire. Ten species of small mammals were captured through all the seral stages of succession. Species richness ranged from two to seven species by seral stage. The species were arranged in different groups with respect to abundance along the succession: the first was composed of early successional species that peaked -2 years after fire (Calomys callosus, C. tener, Thalpomys cerradensis, Mus musculus, Thylamys velutinus); the second occurred or peaked 2-3 years after fire (Necromys lasiurus, Gracilinanus sp., Oryzomys scotti). Gracilinanus agilis peaked in the last seral stage. Species richness of small mammals showed an abrupt decrease from an average of four species immediately after fire to two species 5-26 years after the last fire. We propose a simple graphical model to explain the pattern of species richness of small mammals after fire in the cerrado. This model assumes that the occurrence of species of small mammals is determined by habitat selection behavior by each species along a habitat gradient. The habitat gradient is defined as the ratio of cover of herbaceous to woody vegetation. The replacement of species results from a trade-off in habitat requirements for the two habitat variables.
