Ocorrência e distribuição espacial de mamíferos não-voadores em reflorestamento no sudeste do Brasil

The Conservation in countrysides landscapes only it will be understood in the context of the habitat fragmentation that have been affected the species richness, abundance and distribution. We carried out a mammal survey in platation forest at São Paulo State and 8 we discussed the species richness comparing with others sites surveyed elsewhere. We investigate the landscape influence in the mammal species distribution through spatial analysis. The absence of primate species in plantation forests appear to be a pattern for this environments. The species richness was similar among areas and it was higher when there have contiguous native forest remnants. Moreover the landscape interference don’t appeared affect the mammal species distribution. In overview the landscape connectivity is ameliorate with forest plantation. However, those species more susceptible to extinction in fragmented landscape only can persist when there are contiguous forest fragments from the plantation forests. The management of plantation forests can improves the conservation value for medium and large size mammals species at countryside landscapes.

Proposta de restauração de mata ciliar utilizando técnicas de nucleação no município de Regente Feijó

This monograph, presented in order to obtain the title of Environmental Engineer, proposes the use of nucleation techniques for the restoration of permanent preservation areas formed by three springs that contribute to the formation of Santo Anastacio river, city of Regent Feijo – São Paulo. Through Mine Water Project, landowners are encouraged to restore and conserve springs that contribute to the public water supply, being paid through the fees for environmental services. Once the simulation of this payment was reached at R$ 630.00 per year. Nucleation techniques will be proposed in order to facilitate the ecological succession, through techniques known as transposition of the soil, transposition of the branches, artificial perches and planting in groups of Anderson, totaling 81 cores covering an area of 208.3 m2 which corresponds to 1.9% of the total area to be restored. Made the survey of forest fragments in the watershed, it was found that only 12.39% of the total area has remnant vegetation

Efeito da matriz na capacidade de aves flrestais moverem-se na paisagem

Matrix can be defined as a portion of the landscape, that somewhere in time suffered intense human disturbance, such as decreasing of native vegetation. The matrix surrounding the forest fragments may create a certain resistance to the movements of individuals (RICKETTS, 2001). The Atlantic rainforest present in the Corumbataí river basin lost about 89% of its original vegetation, leading to a highly fragmented landscape (VALENTE e VETTORAZZI, 2005). In this context, this study aimed to evaluate the effect of the matrix and the characteristic capacity of two forest birds, Dysithamnus mentalis and Basileuterus flaveolus, moving around the landscape. With this aim, six fragments were selected, three with sugar cane matrix, three with Eucalyptus sp. matrix. The methodology utilized to evaluate the response of the birds was playback technique. First the vocalizations were carried out at the forest matrix boundary, in the edge, attracting individuals to the matrix. As the responses were generated, the playback was moved increasingly inside the matrix, observing the distances traveled by the species. The control trials were conducted inside the fragments, the playback was played at the edge and as the responses were observed, the vocalizations were carried out inside the fragment until the moment that individuals ceased answers. It could be observed that for individuals of D. mentalis the matrix generated a high resistance, because no individual entered the matrix. For B. flaveolus the average distance traveled in both matrices was 70 meters, indicating statistically high resistance of the sugar cane matrix and Eucalyptus sp. Considering the characteristics of different matrices, it was found that both matrices generate similar resistance in the movement of these species

Composição e distribuição florística em corredores ecológicos em regeneração natural

The interventions in the environment performed by humans in recent decades have changed the landscape and the natural ecosystems were reduced to fragments, which are now considered to be a shelter for the biodiversity that still exists. The present work behind the data obtained from a study conducted in four corridors located in the municipality of Paulista, SP, which connect different forest fragments amidst an eucalyptus matrix. These corridors are linear strips of land that were part of the eucalyptus plantation, where since 2002, a natural regeneration process is in course. We conducted a rapid ecological survey in the central corridors, and individuals exhibiting height ≥ 1.30 m were sampled in 268 plots of 20 x 25 m, covering an area of 13.4 ha. In total 11,111 individuals were recorded, distributed in 154 species, 100 genera and 47 families. Fabaceae and Myrtaceae were the richest families. The proximity of forest remnants affected the composition, density and richness of the natural regenerated areas. There was mostly greater similarity inside each corridor, and the observed variations in similarity were gradual among contiguous plots

Aplicação dos conceitos da ecologia de paisagem para a definição de hotspots de conservação e de conectividade entre o Complexo Cantareira e Nazaré Paulista

The Atlantic Forest biome, reduced to 12% of its original coverage, holds a significant portion of brazilian biodiversity, with high levels of endemism. Among the few remaining areas of the Atlantic, there is the region between the Complex of Cantareira and the municipality of Nazaré Paulista, which will be the object of study of this work. Using the concepts of Landscape Ecology, and analysis of thematic maps, this study aims to characterize the region in a ecologically scaled perspective, identifying two types of hotspots: i) for conservation and ii) for maintain habitat connectivity. Concepts of Landscape Ecology as landscape structure, patches, matrix, corridors (structural and functional) and connectivity, as well as their effects on local biodiversity was adopted and applied in the study region. We also analyzed the effects of roads, hydrographic system, Permanent Protection Areas (PPAs), and Conservation Units for flora and fauna maintenance at regional scale. This allowed us to define strategies and priority areas for the conservation and restoration of forest fragments of Atlantic Forest remnants within the study region. This study generated relevant knowledge for a better planning the region in order to create best conditions for the maintenance of regional biodiversity, and consequently, allowing to improve the quality of life for local population

Processo de uso e ocupação do Pontal do Paranapanema-SP: perspectiva das unidades de conservação (UCs)

The current concern with environmental issues by the scientific community, governmental and civil society also brings out the need to recover, preserve and conserve the environment. With this understanding, this work was prepared, which had as one of the main objectives of the historical process of land use and occupancy of the Pontal, since the nineteenth century to the present day. From this, the changes were evident in the types of land use, which rose from native forest to plant crops (permanent and temporary crops) and later as pasture. Through this process of occupation, exploitation of forests and replacement even three, Reserves being brought from the Far West Paulista, through the state government of Sao Paulo, they were almost decimated. Such areas decreed by law to be preserved and conserved, with the rampant occupations, were suffocated by the fakes and illegal occupation of land tenure contracts, leaving the region currently only a few forest fragments and protected areas of State Park Morro do Diabo, PRNP Boa Vista and Ecological Station Black Lion Tamarin. Furthermore, the article emphasizes the main legislation being developed by federal and state levels aimed at protecting natural resources and the effectiveness they had with the passage of time, demonstrating that the conservation of the environment, has several contributions in the law, however, and they are so vast that hinder its application.

Mamíferos de Médio e Grande Porte de Uma RPPN No Município de Jaú, Estado de São Paulo

The medium to large-sized mammals make population control of invertebrates and vertebrates, as well as seed dispersers are also important. Are losing territory and living area because of deforestation and fragmentation of natural areas, mainly in the Atlantic Forest. The RPPN Amadeu Botelho, in the municipality of Jaú, São Paulo State, is one of the last forest remnants of interior paulista. It is isolated from other forest fragments and thus is a wildlife refuge in the region of Jaú, Midwest of the State. Animals as Pumas (Puma concolor), ocelot (Leopardus pardalis), cat-Moorish (Puma yagouaroundi), have already been sighted in the reserve by officials and residents. The buffer property of the farm Santo Antônio dos Ipês, is surrounded by several plantations, and is very close to the Centre of the city of Jaú. In addition to the lifting of the reservation, it sized mammal species diagnosed the influences that the activities of the farm and the proximity to the Centre of the municipality of Jaú exert to fauna studied

Levantamento da mastofauna e identificação das influências antrópicas em dois fragmentos de Mata Atlântica transição com Cerrado de Rubião Junior – Botucatu - SP

Atlantic Forest and Cerrado are between the biological richest areas in the world, for that are considered top conservation priorities. Those ecosystems are found at Botucatu region, where it´s extremely fragmented by routes, agricultural areas and urban centres. This fragmentation causes restrictions on animals populations, in particular to medium and large mammals, that needs larger areas to live and also are often hunted. Even isolated and suffering anthropic influences the fragments are fundamental for local biodiversity conservation. We realized a mammal survey on two forest fragments of Atlantic forest transition to Cerrado of Rubião Júnior – Botucatu – SP – Brazil: Santo Antônio Church and Parque das Cascatas forests. The Santo Antônio church munt is considered a turistic point and its forest receive many visitants, Parque das Cascatas forest is inside of a residential condominium. Both areas are classify as semidecidual stational forest and are disconected by Domingos Sartori route, that connect Botucatu centre to Rubião Júnior district. Around both fragments can be found residences, plantations and pastures. The utilized method included: recognition of tracks on the forests, interviews with next residents and sand plots mounting. The interviews indicated 29 mammals species, and 19 was validated for animal traces, overruns or visualization. Other 3 species found were not mentioned on interviews. Totally, was found 22 small and medium mammals presence evidences on both forest fragments. Parque das Cascatas forest showed more diversity (19) then Santo Antônio Church forest (11), and species like Eira barbara, Procyon cancrivorus, Mazama americana, Shiggurus villosus, Dasypus novemcinctus, Didelphis albiventris, Lutreolina crassicaudata and Lepus europaeus looked for other areas once that was verifyed overruns of individuals...

Regeneração natural em ecounidades maduras e em reorganização de fragmentos de Floresta Estacional Semidecídua

The Atlantic Rainforest biome has been going through fragmentation processes caused by agriculture and urbanization in green areas. Structural studies associated with the silvigenetic approach allow the understanding of what the past has caused in the present structure and predict future conditions of disturbed fragments. The objective of this study was to compare the composition and diversity of arboreous natural regeneration of steady-state and reorganization ecounits in two Seasonal Semideciduous Forest fragments. The hypothesis was that specific composition varies in these two different ecounits due to differential adaptation of species in canopy gaps and closed canopy. The survey was made in three areas with different perturbation backgrounds of 0,5 ha each. 60 permanent plots of 4m² each (2m x 2m) were stablished along the studied fragments following the proportion of ecounits presented in a previous mapping. Each plot was divided in 4 sub-plots of 1m² and arboreous individuals between 0,20m and 1,30m height were sampled and posteriorly separated in two height classes: I) individuals between 0,20m and 0,50m height (2m² sampling) and II) individuals between 0,51m and 1,30m height (4m² sampling). It was sampled 338 individuals from 53 families and 23 species. The Shannon index was 3,26 (Area A), 2,27 (Area B) and 2,42 (Area C) whereas Areas B and C values are considered low in our state Semidecidous Forests. Steady-state ecounits presented the highest values for abundance and species richness. Chi-square test pointed out species’ selection for determined ecounits in the studied community. Rarefaction method analysis showed diversity increase in steady-state ecounits and a stablishment in species richness curves for reorganization ecounits
