The impacts of forest fragmentation on the pteridophyte communities of the Una region of Bahia, Brazil, were investigated by comparing species richness and ensemble diversity among areas of large forest fragments (>900 ha), small forest fragments (<100 ha), and landscape matrix. We inventoried the pteridophytes below 1 m in height in interiors of small fragments, interiors of large fragments (control areas), edges of fragments, edges of continuous forest, capoeiras (initial stages of forest regeneration) and cabrucas (cocoa plantations). All ferns were collected following the plot method (plots of 120 · 10 m, each). Sampling units were established in the six main ecotypes of the Una region. These units were allocated within three sampling blocks of 5 per 5 km, which were chosen in order to include the largest forest patches that still remain. Results suggest that fragmentation has a negative impact on species richness at the matrix and the edges of forest remnants. A similar negative matrix end edge effect is reported for diversity of those sites measured by the a Log-series Index. However, small forest fragments have pteridophyte species richness and diversity rates similar to large ones so they should be considered of utmost importance to the conservation of forest-related species in the region.

“…They recorded five small mammal species in the simplified environment of a cocoa plantation shaded by rubber trees (Hevea brasiliensis, Euphorbiaceae) with complete suppression of the herbaceous stratum; seven species in a similar plantation where the herbaceous stratum was maintained; and 12 species in a cabruca with complex shade canopy whose understory had not been slashed for 3 years. The structural complexity of the vegetation was also suggested by Pinto et al (1993) to be a determinant of the richness and abundance of small mammals in a comparison of native forest, an oil palm plantation, a cocoa plantation shaded by rubber trees, and a cabruca.…”

Landscape and farm scale management to enhance biodiversity conservation in the cocoa producing region of southern Bahia, Brazil

et al. 2008

In southern Bahia, Brazil, large land areas are used for the production of cocoa (Theobroma cacao), which is predominantly grown under the shade of native trees in an agroforestry system locally known as cabruca. As a dominant forest-like landscape element of the cocoa region, the cabrucas play an important role in the conservation of the region's biodiversity. The purpose of this review is to provide the scientific basis for an action plan to reconcile cocoa production and biodiversity conservation in southern Bahia. The available research collectively highlights the diversity of responses of different species and biological groups to both the habitat quality of the cabrucas themselves and to the general characteristics of the landscape, such as the relative extent and spatial configuration of different vegetation types within the landscape mosaic. We identify factors that influence directly or indirectly the occurrence of native species in the cabrucas and the wider landscape of the cocoa region and develop recommendations for their conservation management. We show that the current scientific knowledge already provides a good basis for a biodiversity friendly management of the cocoa region of southern Bahia, although more work is needed to refine some management recommendations, especially on shade canopy composition and density, and verify their economic viability. The implementation of our recommendations should be accompanied by appropriate biological and socioeconomic monitoring and the findings should inform a broad program of adaptive management of the cabrucas and the wider cocoa landscape.

ResumoAdiantum L. é um gênero facilmente reconhecível pela presença de pseudo-indúsio com nervuras, formado pela margem revoluta da lâmina. Compreende espécies terrestres ou epipétricas. É um grupo Pantropical com cerca de 200 espécies, sendo que 70 delas ocorrem na América do Sul e 62 no Brasil. Adiantum ocorre principalmente no interior de florestas primárias e secundárias, desde o nível do mar até cerca de 2.000 metros de altitude. Visando-se o conhecimento regional do grupo no Brasil, o presente trabalho apresenta o levantamento do gênero Adiantum no estado do Rio de Janeiro, fornecendo chave de identificação, descrições, comentários e ilustrações das espécies. Existem 20 espécies de Adiantum no Estado, correspondendo a 30% do número total registrado para o Brasil e podem ser encontradas desde florestas úmidas até restingas, desde o nível do mar até 850 metros de altitude. Dentre as espécies inventariadas, algumas possuem ampla distribuição na América Central e América do Sul (70%), enquanto outras são endêmicas do Brasil (30%). Palavras-chave: Adiantoideae, Floresta Atlântica, samambaias, taxonomia. AbstractThe genus Adiantum L. can be easily recognized by the pseudoindusium formed by the revolute margin of the lamina and with veins. The species of this genus are terrestrial or lithophytics. It is a Pantropical group with approximately 200 species, 70 of which occur in South America, and 62 in Brazil. Its species are usually found in primary and secondary forests, from sea level to 2,000 meters. Aimed the regional knowledge of this group in Brazil, this study reports a floristic survey of the genus Adiantum to the state of Rio de Janeiro, providing an identification key, descriptions, comments, and illustrations of the species. There are 20 species of Adiantum in the state, corresponding to 30% of the species recorded to Brazil. They can be found in rainforests and sandy coastal plain vegetation, from sea level to 850 meters. Some species have a wide range of distribution in Central and South America (70%), whereas others are endemic to Brazil (30%).
