“…In the literature, there is a great deal of discussion with respect to the recent changes in the Brazilian Forest Code (AB 'SÁBER, 2010;BRANCALION;RODRIGUES, 2010;CASATTI, 2010;DEVELEY;PONGILUPPI, 2010;TOLEDO et al, 2010;TUNDISI;MATSUMURA-TUNDISI, 2010), in which a false dichotomy is apparent between the conservation of native vegetation and farming, which according to Martinelli et al (2010), affects various ecological communities. With respect to the ligneous vegetation in PPAs, there are few studies discussing the possible alterations resulting from the changes in legislation (PINHEIRO et al, 2015).…”

Ecological Aspects Related to Ligneous Vegetation in the Permanent Preservation Areas of Mineiros, Goiás, in Light of the New Native Vegetation Protection Policy - Law 12.651/2012

-Permanent preservation areas (PPAs) adjacent to drainage channels may include forests, savannahs, or grassland Under a former environmental legislation ("Forest Code"), it was required to maintain a strip of native vegetation (at least 30 m wide) at the margin of any drainage channel, to support environmental functions. Under the current native vegetation protection policy, if a riparian margin was degraded prior to 2008, the landholder is required to regenerate a strip of only 5-20 m, in some cases. The present study evaluated and compared the ligneous vegetation structure in 10 preserved PPAs (following the requirements of the old law) and 10 degraded PPAs (conforming to the current environmental legislation), in Mineiros municipality, southwest Goiás. Sixty plots measuring 15 m × 30 m were delineated, and data for all ligneous individuals with a diameter at breast height (DBH) > 5 cm were recorded. A total of 2,662 individuals were documented, distributed among 208 species. Of the total, 1,573 individuals belonging to 167 species were from the preserved PPAs, and 1,089 individuals across 142 species were from the degraded PPAs. According to these results, the preserved PPAs were richer in species composition than in the degraded PPAs (245.5 ± 34.36 and 213.3 ± 34.1, respectively), in addition to being more abundant in terms of individuals. The importance value index (IVI) was well distributed among the species. All the degraded PPAs presented signs of erosion. It was concluded that the reduced width of the PPAs (5-20 m) under the current native vegetation protection policy would result in a loss of the environmental functions sought by the legislation..

“…The preference for riverine forests by insectivorous passerines in the Atlantic Forest and other threatened passerines in Brazil is well known (Anjos et al 2007, Develey and Pongiluppi 2010, Metzger 2010. These wetter microenvironments may have a higher abundance of insects (Powell et al 2015).…”

Understanding the distribution of a threatened bird at multiple levels: A hierarchical analysis of the ecological niche of the Santa Marta Bush-Tyrant (Myiotheretes pernix)

Artículo de publicación ISIAn understanding of the ecological factors determining bird species’ distributions is essential for making informed conservation decisions. These data are especially important for range-restricted species, such as the Santa Marta Bush- Tyrant (Myiotheretes pernix), a threatened endemic of the Sierra Nevada de Santa Marta (SNSM) in Colombia. Here we adopt a novel hierarchical analysis to describe the bush-tyrant’s ecological niche and infer the regional and local determinants of its limited distribution. We first describe habitat selection based on local habitat use and microhabitats used for foraging. We then use a geoprocessing modeling algorithm to combine habitat selection data with a climatic niche model. The resulting model produced an index of habitat suitability, which we converted into a predicted geographic distribution. Santa Marta Bush-Tyrants showed no clear habitat preferences, but favored forested and secondary growth habitats over open areas, at elevations between 2,100 and 3,300 m. The species’ predicted distribution was restricted to the northern flanks of the SNSM, with an estimated extent of ~352 km2. This estimate is more restricted than previous estimates (570 km2), but does not alter the species’ status as Endangered based on IUCN criteria. The model predicted that the presence of Santa Marta Bush-Tyrants was regionally dependent on cold and humid climates, with low annual variation in temperature and precipitation. Locally, the species’ presence was determined by the availability of habitat edges between forests and open areas. Conservation actions should aim to reduce rates of forest loss, while maintaining the presence of areas with good light and exposed perches, microhabitat conditions typically found in habitat edges or areas of natural disturbance. An explicit integration of quantitative data on habitat use and foraging patterns into niche models would help to obtain more realistic and detailed projections of the occupied distribution of range-restricted birds

Brazil is the country with the most biodiversity in the world and also hosts the largest rainforest on the planet. Although Brazil was a pioneer of public policies for conservation of biodiversity and natural resources, it has recently jeopardized all biome conservation through questionable environmental policies. Over the past four years, the government has drastically altered its environmental legislation, removing vast areas from protection and encouraging overexploitation of natural resources,, which will result in loss of biodiversity, reduction of forest cover, and increased pollution of soil and water. The Brazilian political-social scene and its relationship with biodiversity conservation are discussed as well.
