Em cativeiro, Pinguins-de-Magalhães, Spheniscus magellanicus (Forster, 1781) (Sphenisciformes, Aves) são descritos como sedentários, obesos, pouco interativos e apáticos, costumam apresentar pododermatite e baixo índice de reprodução. Atualmente, existem poucos estudos relacionados a pinguins de cativeiro, dificultando o trabalho de manejo e conservação. Diferentes parâmetros podem ser utilizados para avaliação do bem estar animal, dentre eles a diversidade comportamental e repertório típico da espécie. O presente estudo objetivou avaliar o orçamento temporal e o padrão de distribuição do comportamento de um grupo de seis animais ao longo do dia e em épocas do ano distintas, e relacionar os comportamentos aos indicadores do estado de saúde dos pinguins. Foram estudados animais residentes no Parque Escola SABINA, em Santo André, SP, nos meses de janeiro, março, maio e julho de 2014. O comportamento dos animais locais foi observado por dois dias nos seguintes horários: 8h-8h50min, 9h25- 10h15min, 10h50min-11h40, 12h20-13h10, 13h40-14h30, 15h05-15h55. As lesões de pododermatite foram classificadas seguindo o escore padronizado de 1 a 3 para a classificação de pododermatite nos pinguins. Foi observado que nenhum animal apresentou lesões avançadas de calosidades nas patas, porém quatro demonstraram evolução no bumblefoot. Os animais passaram mais tempo nos seguintes comportamentos: repouso em pé, repouso deitado, nadar, banho, arrumar penas. A duração dos comportamentos variou entre os meses: no mês de julho os pinguins passaram mais tempo nadando e banhando-se e houve uma tendência de redução do repouso. A distribuição dos comportamentos entre os períodos da manhã e da tarde foi distinta dependendo do mês. Em geral, os pinguins passaram mais tempo banhando-se e nadando pela manhã e em repouso à tarde. Dessa forma, os animais apresentaram variação sazonal que seria esperada em condição de vida livre,...

Planning and sustainable management of water resources require actions that focuses on life quality, recovery and preservation of natural resources. As such, a municipality must have tools which empower the government with the right to exercise such actions, for example, the Master Plan and Sector Plans. To develop municipal plans which will guide the development of the city and provide information for establishment of public policies, it is of the utmost importance that they are designed based on primary and safe data. In view of these considerations, this study aimed at formulating environmental indicators by using a Geographic Information System – GIS. The environmental diagnosis based on the gvGIS was used as database, which made the process to be agile and accurate. The watershed of Lençóis River – SP was the study area. It has a good database from the Environmental Diagnosis of the watershed of Lençóis River, which was created through funds from the State Funds for Water Resources – FEHIDRO. The borrower was the Service of Water Supply and Sewage of Lençóis Paulista – SAAELP. Based on the diagnosis, the indicators were formulated concerning land use and occupation as well as water resources. The results were considered satisfactory and showed that the methodology used in this study is of great importance to evaluate water resources, as it provides a reliable basis for the decision-making process seeking environmental compliance and sustainable development. By using environmental indicators, the sustainability of an area as a whole can be analyzed, and the parts as well, i.e., it is possible to identify which sector is experiencing significant problems and take actions to solve them.

The constant misuse of land in Permanent Preservation Areas (APPs) have been recurrent, especially in urban areas, where the dynamics of change is constant. The protection of these areas to maintain a balance in the ecosystem and the population's quality of life is fundamentally important. So it is of utmost important to draw up a mechanism that can help in decision-making in relation to measures for the protection, mitigation of damages that are being caused and revitalization of these areas. Thus, a managing these areas based on the PMBOK (Project Management Body of Knowledge) in order to create mechanisms to facilitate the protection and revitalization of APPs, could be of great help for making public decision-making bodies that are entrusted to protect such areas. Based on this, we elaborated a project management in order to revitalize and protect the APPs in urban area of Rio Claro, SP and could become a model for future use by public bodies

The city of Lençóis Paulista has a great part of its agricultural land cultivated by sugar cane and reforestation of eucalyptus and pine trees. In the county there are industries that exploit energy extracted from energy cogeneration. The city of Lençóis Paulista, in recent years, has been demonstrating considerable levels of economic and social growth with the industries that are working with sugarcane and eucalyptus mainly responsible. However, the expansion of agricultural land in many cases does not take into consideration the permanent preservation areas that are protected by the law. The APP's are of fundamental importance in the management and conservation of the environment preserving the natural plants and wildlife, and also preventing erosion and the silting of drainage networks. This objective of this study was to diagnose land use, analyze if Permanent Preservation Areas are regulated to the Brazilian Forestry Code (1965) and also diagnose areas of conflict. In relation to the use and occupation of land, the research has shown how the land is divided (agricultural crops and urban zones), and highlighted areas of conflict with the Permanent Preservation Areas. All of the information is contained in maps using Geographic Information Systems. However, it has become clear that environmental laws are not respected as much in urban areas as they are in rural areas. The PPA's are virtually nonexistent, thus creating damage to the environment and local population.

O grande desafio da população mundial é a conservação ambiental, pois as Áreas de Preservação Permanentes, que têm papel vital dentro de uma microbacia, por serem responsáveis pela manutenção, preservação e conservação dos ecossistemas ali existentes. O presente trabalho visou analisar os conflitos de uso do solo em áreas de preservação permanentes (APPs) da microbacia do Alto Capivara - Botucatu (SP) através do uso de Sistema de Informações Geográficas e de imagem de satélite digital. A área com 4551,19ha, situa-se entre as coordenadas geográficas: 22o 51’ 57” a 22o 57’ 55” de latitude S e 48o 21’ 58” a 48o 26’ 38” de longitude WGR. O mapa de uso do solo de 2006 foi obtido a partir da classificação supervisionada em imagem de satélite digital de 23/10/2006. Na identificação digital dos alvos foram utilizadas as chaves de interpretação para imagens e as áreas foram determinadas através do software SIG – IDRISI. Os conflitos de uso nas áreas de preservação permanente foram analisados ao longo da rede de drenagem e das nascentes, conforme itens dos artigos 2º e 3º da Resolução nº 303 do CONAMA. A área de APP discriminada ao longo da rede de drenagem foi de 416,5ha (9,15%) . No entanto, 201,15ha da área de APP está ocupada com pastagem (48,3%), reflorestamento (1,23%) e 0,48% por área urbana de forma inadequada (conflito). Portanto, quase 50% de área de APP vem sendo parcialmente utilizada adequadamente.

Over the past few years, the area of planted forests has expanded considerably in Brazil, reaching a level of 6.3 million hectares, which represents approximately 0.7% of the country, mainly with some species of the Eucalyptus genus. However, due to the global concern with biological invasions by exotic species, risk assessment is necessary to evaluate the potential of Eucalyptus species escaping cultivated stands and invading surrounding native ecosystems. Seedlings by natural regeneration from Eucalyptus grandis and E. urophylla, pure and hybrids between the two species were evaluated, by assessing natural regeneration of Eucalyptus in 18 sites located in Brazilian states with plantation forest tradition (Minas Gerais, São Paulo, Rio Grande do Sul and Espírito Santo). Sample plots were installed in the planted stands, along forest roads and in a nearby pasture or native vegetation.,at different distances from the Eucalyptus stands. Regeneration of Eucalyptus was not recorded in 90% of the plots installed outside the eucalipt stands. However, seedlings of eucalypts were observed in 29% of the plots within the commercial stands (mean density of 37 seedlings per hectare) and 40% of the plots located along forest roads (157 seedlings per hectare on average), but no adult plants by natural regeneration were found. The seedlings of eucalypt species studied rarely were found beyond the limits of the cultivated areas. In the planted stands or along forest roads, eucalypts can germinate, but the seedlings apparently do not establish. So the potential for invasion by seeds produced in commercial plantations of Eucalyptus is low.
