Determinação de áreas prioritárias para conservação na zona de amortecimento de UC de proteção integral: o caso da Estação Ecológica de Ribeirão Preto, SP

Observa-se como estratégia mundial para a conservação da biodiversidade a criação de unidades de conservação. No Brasil, especificamente no Estado de São Paulo, devido a intensa degradação da Mata Atlântica, verifica-se a criação de unidades de proteção integral, a fim de se preservar de modo restrito os recursos naturais que ainda lhe restam. Na cidade de Ribeirão Preto, uma região com alto desempenho agrícola e intensa expansão urbana, constata-se a presença de uma Estação Ecológica (EERP), fragmento florestal de 154,16 ha, altamente isolado e fragmentado. Assim, a EERP e sua zona de amortecimento (ZA) vêm sendo fortemente pressionada pela expansão urbana e agrícola da região, comprometendo a sua integridade ecossistêmica. Dentre os impactos negativos gerados destacam-se: alta especulação imobiliária e o intenso cultivo de monoculturas, que contribuem para a degradação do solo nas regiões do entorno. A fim de se reduzir tais impactos, o presente trabalho buscou apresentar um prognóstico de planejamento ambiental para a ZA da EERP, a qual se encontra altamente impactada, segundo os critérios definidos por Ranieri (2004). Desse modo, criou-se cenários ideais para a preservação dos recursos naturais do local

Comportamento fenológico da liana Pyrostegia venusta (Ker Gawl.) Miers (Bignoniaceae) em área de cerradão na Estação Ecológica de Assis, SP.

Brazilian cerrado is characterized by an evident seasonality with distinct dry and wet seasons. Pyrostegia venusta is a common vine found in different physiognomies of the Cerrado. The species may present characteristics that allow its adjustment to the seasonal cycles. The phenology of vegetative and reproductive events was studied for this species in 2004 and 2005. The objective was to verify which climatic factors determine the phenological patterns observed in the species. Flowering was inversely related to mean temperatures and to the length of the day, while fruiting was inversely related to the photoperiod and directly related to the mean wind velocity. Seed dispersal was directly related to wind speed. As a consequence, flowering occurred at the end of the rainy season, close to the winter, and was prolonged until the end of the dry season. Fruiting and fruit maturation occurred during the dry period, with the seeds being dispersed at the end of this period. The seed dispersal at the end of the dry season, common to other anemochoric species of cerrado, allows a rapid germination at the beginning of the wet season, favoring the species propagation in this environment.

Produtividade, estabilidade e adaptabilidade em progênies de Myracrodruon urundeuva F.F. & M.F. Allemão – Anacardiaceae

The use and inadequate exploitation of natural resources is restricting the occurrence of aroeira (Myracrodruon urundeuva F.F. & M.F. Allemão), which now is on the FAO list of endangered species. This exploitation causes a decrease in the genetic base of M. urundeuva populations, which makes it difficult to find genotypes with stability and adaptability to different growing conditions. This study aimed at estimating the genetic variation and productivity, stability and adaptability of progenies of a M. urundeuva natural population, from the Ecological Station of Paulo de Faria-SP, under different planting systems. DBH (diameter at breast height) was evaluated in four progeny tests of M. urundeuva: i) planted with Anandenanthera falcata and Guazuma ulmifolia (TP-AMA); ii) single (TP-ASO); iii) planted with annual crops (TP-SAF) and iv) planted with Corymbia citriodora (TP-EUCA), installed in Selvíria-MS. The experimental design consisted of complete randomized blocks with three replications and a variable number of plants per plot in each of the four planting systems. From the joint analysis of the planting systems studied, it was found that: i) there were variations among planting systems particularly in TP-SAF; ii) only in TP-EUCA it was possible to detect variations among the progenies; iii) the effects of the genotype x environment interaction were not significant. Thereby, the harmonic mean of genotypic values (MHVG), the relative performance of genotypic values from the mean of each site (PRVG) and the harmonic mean of the relative performance of genotypic values (MHPRVG) for DBH showed, respectively: progenies with greater stability, adaptability, and stability and simultaneous adaptability within different planting systems. The use of these selection criteria provided a more refined selection of the best progenies of M. urundeuva under the different planting systems studied.

A inclusão da natação na vida da pessoa com deficiência: uma análise a partir da teoria ecológica do desenvolvimento

The objective of thisstudy was to verify, using the Ecological Development Theory (EDT), as the practice and swimming learning for People With Disabilities (PWD) causes changes to both the practitioner and in other environments experienced by it as well as the other environments influence the learning to swim. The study included 16 PWD, students linked university extension project, Department of Physical Education of UNESP Bauru, taught by coordinators LAPEF, which aims to includes wimming in the PWD ofevery day life, students linked to an institution of Bauru-SP, three employees of the institution and two swimming project teachers.Interviews with the families of the students were made, with the institution s employees, with the project teachers and analyze thes wimming lessons applied in the project for one semester. Based on the results we can say that the practice and learnings wimming for PWD causes changes to both the practitioner and for other environments experienced by her (home, institution) and also, what other environments experienced by PWD influence in practice and process of learning to swim. Using the terminology of EDT, we conclude that theme so system (home activities institution) influences in the microsystem (swimming lessons) and the microsystem influences the mesosystem, so the activity was significant and temporal persistence influencing the development of PCD.

Documentação química de espécies do gênero Casearia (Salicaceae) de importância ecológica, econômica e medicinal

The Casearia genus (Salicaceae) is well known because of the medicinal use of its species. Among them, a noteworthy one is the C. sylvestris specie because it already has studies concerning its antiproliferative and/or cytotoxic activity in tumor cells. Furthermore, this specie is popularly used against snake bites, in gastric ulcers treatment and as anti-inflammatory. As well as this, there are other species from this same genus which have been poorly studied, such as the following species: C. decandra, C. grandiflora, C. javitensis, C. arborea, C. lasiophylla and C. ulmifolia. However, several biological activities have been reported for them. In this context, the aim of this project, besides of contributing to the Casearia genus studies, is to study those six species through the analysis and documentation of their leaves' chemical composition (aqueous, ethanolic and hexanic extracts), using analytical separation techniques coupled with spectroscopic techniques, such as UHPLC-DAD, GC-MS and NMR 1H, which will assist the identification of new secondary metabolites in this genus. Moreover, another goal of this present work is aiming the bioprospection of substances with medicinal and economical potential and finally promote the systematic study of some biological activities, such as antimicrobial and cytotoxicity bioassays. A wide variety of metabolites was identified in those three types of extracts, being most of them detected for the first time in Casearia genus, highlighting C. lasiophylla and C. decandra for featuring antimicrobial activity against Staphylococcus aureus.
