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.

Environrnental issues are in focus lately, mainly due to climate change that have been registered in recent decades. Some of these changes are attributed to the increased atmospheric concentration of greenhouse gases induce, main1y due to anthropogenic emissions. These gases act by absorbing heat in the form of electromagnetic radiation emitted by the planet, and after a time interval, reissuing such radiation in various directions, including back to the surface, causing overheating of the same. Projections indicate that climate change wiIl tend to increase even more. Because of this, in recent years a number of studies are being conducted on the dynamics of inducers of greenhouse gases, especially C02, because that is primarily responsible for the development of that phenomenon. To better understand the flow of C02 are studied specific areas, as regions bordering the forests, soils that are under preparation for agriculture, urban areas, among others. Forests are an important sink for C02, because during the process of photosynthesis, this molecule is captured and used to obtain glucose. Thus, studies of the regions bordering the forests contribute enough to the understanding of the dynamics of C02. Because it requires a large amount of factors, the concentration of CO2 in a given location is very variable and this makes it much more difficult to understand their dynamics and, consequently, the action of the enhanced greenhouse effect. Being a relatively new area of study, there are many controversies about the consequences of the greenhouse effect, so that the community does not believe that climate change resulting from human action. According to them, such changes are merely natural phenomena and periodicals

In Brazil, there are three main codes that surround the issue of right or possession of various lands according to concepts of ownership or purchase. When it comes to indigenous issues in Brazil is difficult to say which legal code applies more fairly the native population of the country. In the case of the Indians who have their reserves near urban areas there is such a conflict of laws becomes more evident and takes even greater than in other regions of Brazil. As is the case in the indigenous villages of the District of Jaragua in Greater São Paulo, the Tekoá YTU and Tekoá Pyau. The two villages are located in northeastern São Paulo and currently are surrounded by continuous growth and disorderly city of Sao Paulo while their inhabitants fight to preserve the customs and traditions of the Guarani people. They prevail on the City Statute (2001), the Indian Statute (EDI) Environmental Laws and the National Council of Environment (CONAMA) and the Forestry Code, the latter solely because they are near the State Park Jaragua - area environmental preservation

Os anfíbios ocupam grande variedade de microhabitats refletindo os diversos modos reprodutivos, estilos de vida e parasitas que estes animais apresentam. Os parasitas são indicativos de muitos aspectos biológicos de seus hospedeiros, incluindo a dieta, ocupação do habitat e a filogenia, podendo também ser bons indicadores diretos do estado de qualidade ambiental. A Ilha Anchieta, parque estadual em área de Mata Atlântica, torna-se interessante para estudos biológicos devido a sua dinâmica insular e isolamento geográfico. No Brasil, a Mata Atlântica é um dos biomas mais afetados pelas atividades antrópicas e o número de helmintos recém-descobertos podem estar desaparecendo mais rapidamente do que novos organismos são descobertos. O objetivo deste estudo foi caracterizar a helmintofauna de duas espécies de anfíbios, Hypsiboas albomarginatus (n=23) e Scinax hayii (n=18), ambas pertencentes à família Hylidae, procedentes da Ilha Anchieta, São Paulo, Brasil. A helmintofauna foi composta apenas de nematoides (Rhabdias sp., Physaloptera sp.) e um espécime não identificado da família Cosmocercidae. Estudos como estes são importantes, pois os parasitas representam uma diversidade oculta, a qual contribui com a manutenção da diversidade local de hospedeiros e das funções do ecossistema

Na Universidade Estadual Paulista, Câmpus de Jaboticabal-SP, estudou-se o comportamento de Passifloráceas quanto à morte prematura de plantas, cultivadas em local com histórico da doença. O objetivo do trabalho foi avaliar o comportamento de diversos acessos de populações e espécies de maracujazeiros em relação a esta doença, sendo que as plantas resistentes deverão ser utilizadas como porta-enxertos de formas comerciais de maracujá-amarelo (Passiflora edulis Sims f. flavicarpa) e em programas de melhoramento genético. As espécies utilizadas foram P. edulis Sims, P. edulis Sims f. flavicarpa Degener, P. nitida H.B.K., P. cincinnata, P. giberti, P. laurifolia, P. morifolia, P. foetida e P. capsularis. em local com histórico da doença, plantaram-se mudas em número variável e em épocas distintas. A condução das plantas e os tratos culturais foram os recomendados para o maracujá-amarelo. A morte prematura das plantas ocorreu entre dois meses e dois anos da cultura no campo. P. giberti e P. nitida mostraram-se resistente à doença, independentemente do local de origem. Entre os demais acessos, não se encontraram fontes promissoras de resistência. Entretanto, novos acessos e novas espécies deverão ser estudadas na busca da resistência.

Rhagomys rufescens is a threatened Sigmodontinae rodent from the Atlantic forest of southeastern Brazil, known by a few specimens deposited in scientific collections. This work presents a new record of this species, collected in Parque Estadual da Serra do Mar-Nucleo Picinguaba (Ubatuba, SP) in April 2002, and some biological data. This finding reinforces the urgency of improving collecting efforts in Atlantic forest, in order to know and preserve its biodiversity.

Visual communication is widespread among several anuran families, but seems to be more common than currently thought. We investigated and compared visual communication in six species of an anuran community in the Brazilian Atlantic forest. Four are nocturnal species: Hyalinobatrachium uranoscopum (Centrolenidae), Hyla albomarginata, Hyla sp. (aff. ehrhardti), and Scinax eurydice (Hylidae), and two are diurnal species: Hylodes phyllodes and Hylodes asper ( Leptodactylidae). For H. uranoscopum, H. albomarginata, S. eurydice, and H. phyllodes, this is the first record of visual communication. Observations were made at Nucleo Picinguaba, Parque Estadual da Serra do Mar, in the Municipality of Ubatuba, State of São Paulo, Brazil. Descriptions of behaviour were based on individuals observed in the field, using sequence sampling with continuous tape recording for behavioural observations. Eight new behaviours are described: body wiping, face wiping, jump display, leg kicking, limb lifting, mouth opening, toe flagging, and vocal sac display. of the 42 anuran species known from Nucleo Picinguaba, at least six ( approximately 14%) display visual communication. The evolution of visual signals in these species may be related to the availability of ambient light, the structural complexity of the habitat, and/or the ambient noise. They may also have evolved to aid in the location of the individual, to avoid physical combat, and/or may be a by-product of seismic communication.

The pariparoba (Piper cernuum Vell.), a native plant from the Atlantic Tropical Forest (ATF), has been commonly used in folk medicine. Works seeking the exploitation of P. cernuum natural populations need to be accomplished, seeking compatibility in obtaining income rates and preservation of ATF. The present work aimed to study the reproductive phenology and seed dispersal in P. cernuum natural population in the counties of Sete Barras/SP (Parque Estadual Intervales - PEI). The population of P. cernuum studied in PEI presented continuously bud-inflorescences, green-infrutescences and bud-inflorescence emission, with variation among individuals. Fruit-set average was of 9.1%, varying among individuals. Shading and foliar damage presented negative effect on the fruit-set. Three species of bats were identified as potential dispersors of the P. cernuum seeds: Carollia perspicillata, Anoura geoffroyi and Artibeus sp. The foragement strategy observed was the withdrawal of some seeds per infrutescence per flight. This strategy increases the potential in establishing new plants as well as in increase the potential of gene flow in comparison with the entire infrutescence plant eaten at the night perches. In consequence, the results of reproductive phenology and seed dispersal ecology presented in this work can help to establish management and conservation strategies of P. cernuum natural populations in the ATF.
