The present study aimed to survey the medium and large land mammals in three fragments at the Fazenda Experimental Lageado - UNESP/Botucatu, through the method of sand plots. 48 plots were used in total, 16 on each track. The paw prints found were photographed and identified from specific guides. 12 different species of mammals were found, these, 7 were classified at the level of species belonging to 9 families and 6 orders. The most representative order was Carnivora. Most of the species found have a generalist or omnivore habit, which can be related with the degree of the forest fragmentation. The only fragment of natural forest (semideciduous), presented the fewer numbers of species, which can be explained due to its isolation. The other fragment, which has near highway and other large fragment (Fazenda Experimental Edgárdia) was the most representative fragment, demonstrating the importance of nearest fragments to the continuity and survival of medium and large mammals

Gender relationships focusing on homages to the women of Assis (a town in the center-western region of the state of São Paulo, Brazil) between 1959 and 1994, are discussed. Homages, expressed in monuments, street names, city squares, schools, libraries, Cultural Centers and other places, are based on the activities of women who benefitted the community. They feature lawyers, politicians, journalists, teachers and common citizens that exceeded their personal limitations and conquered a place acknowledged by society (politically invested) so that their names may be inscribed in the city´s public places. However, acknowledgement of female contributions in the construction of the city is not projected at the same pace or speed as that of males who compose the gallery of ‘remembered men’. This fact brings forth the following questions: If the naming of public places were for decades based on gender, what had changed by the end of the 1950s for such a redefinition? What is the true meaning of such homages? Who are these women and what do they represent?

Recovery of degraded areas aims to provide the degraded environment favorable conditions for restructuring in an environment that is unable to regenerate itself and planting of tree seedlings is one of the effective ways to extend this process. However, native tree species have slow growth rate which increases the seedlings production time as well as decreases their competitiveness with weeds in areas of forests deployment. The aim of this study was to evaluate the effects of glyphosate reduced rates application on Psidium cattleyanum (yellow guava), Citharexylum myrianthum (pau-viola) and Cedrela odorata (cedro) seedlings development by analyzing its morphophysiological parameters. The experiment was carried out in greenhouse conditions and the experimental units consisted of one plant were conducted in 2.5L plastic pots and arranged in a completely randomized design with six replications. Treatments consisted of glyphosate application at 0, 7.5, 15, 30 and 60 g ha(-1) using Scout (R) commercial formulation. Treatments application on these species seedlings was realized 120 days after seeds germination. Visual evaluations of plants phytotoxicity were realized at 7, 14 and 21 days after treatments application and plants survival, stomatal conductance, height, stem diameter and dry mass of shoots were evaluated 90 days after treatments application. Different doses of glyphosate did not cause plants phytotoxicity. Already, 30 and 60 g ha(-1) of glyphosate provided greater increases in height, stem diameter and dry mass of shoots for Citharexylum myrianthum and Psidium cattleyanum, respectively.

A restauração de áreas degradadas pode beneficiar espécies típicas do ambiente original, com a expansão e criação de habitats, tornando-se uma ferramenta de extrema importância para a conservação. Frugívoros atraídos por plantas zoocóricas utilizadas em plantios não apenas podem dispersar sementes dessas plantas como também trazer sementes alóctones, promovendo a diversidade genética local. Assim, é fundamental entender as condições em que o processo de dispersão de sementes opera, a fim de subsidiar programas de recuperação ambiental. Este trabalho avaliou a importância das espécies: embaúba (Cecropia pachystachya), pitanga (Eugenia uniflora), figueira-do-brejo (Ficus insipida), aroeira-pimenteira (Schinus terebinthifolius), pau-pólvora (Trema micranta), fumo-bravo (Solanum mauritianum) na atração de aves frugívoras em uma Área de Preservação Permanente de 6,2 ha replantada em 2006 no município de Piracicaba, São Paulo. Apenas C. pachystachya, E. uniflora e F. insipida foram utilizadas no plantio, o que indica que as outras espécies foram introduzidas pela fauna. Observações focais foram realizadas em pelo menos dois indivíduos de cada espécie, totalizando dez horas de observação por espécie. Foram registradas 29 espécies de aves alimentandose dos frutos. Utilizando-se de uma adaptação da fórmula de Murray (2000) para o índice de importância na atração da avifauna, foram encontrados os valores de 0,086 para C. pachystachya, 0,031 para E. uniflora, 0,020 para F. insipida, 0,123 para S. terebinthifolius, 0,083 para S. mauritianum e 0,623 para T. micrantha. O grande valor observado para essa última em relação às outras pode ser justificado pelo grande número de espécies visitantes e de relações exclusivas, especialmente com aves que são predominantemente insetívoras ou granívoras. A importância de T. micrantha provavelmente se deve à alta concentração de lipídios em seu fruto. Os...
