Ecologia da paisagem: mapeamento da vegetação da Reserva Biológica da Serra do Japi, Jundiaí, SP, Brasil

Foi realizado o mapeamento da vegetação da Reserva Biológica (REBIO) Municipal da Serra do Japi, Jundiaí, SP, por meio de fotointerpretação analógica, em escala 1:30.000. O mapa foi digitalizado e transferido para computador pelo sistema de informação geográfica (Idrisi) e posteriormente para o programa Corel Draw. Foram identificadas, mapeadas e descritas oito unidades de paisagem (UP) sendo três antrópicas (solo exposto, campo antrópico e reflorestamento homogêneo) e cinco naturais (floresta estacional semidecidual montana dossel uniforme - microfanerófitos; floresta estacional semidecidual montana dossel uniforme - mesofanerófitos; floresta estacional semidecidual montana dossel emergente; floresta estacional semidecidual aluvial dossel emergente e refúgio montano arbustivo). As unidades naturais somaram 98,46% do total dos 2.071,20 ha da área, indicando que a Reserva vem cumprindo seu papel na preservação do ecossistema em questão. No entanto, como algumas unidades não tem expressiva representatividade na área, e como existe grande extensão de floresta no entorno da Reserva, sugere-se a ampliação e a transformação da mesma em uma unidade que contemple inclusive a visitação pública como forma de auxiliar no processo de conservação. Sugere-se que a área seja transformada em parque estadual, cujo nome poderia ser Parque Estadual da Serra do Japi.

Floral biology and late-acting self-incompatibility in Jacaranda racemosa (Bignoniaceae)

Breeding-system studies have been conducted with 38 of the approximately 800 species of Bignoniaceae, and self-incompatibility was found in 31 of these. In species for which the site of self-incompatibility barrier was studied, self-pollinated flowers consistently failed to develop into fruits, even though pollen tubes grew down to the ovary and penetrated most of the ovules. In this study, we have investigated the. oral biology and the breeding system in Jacaranda racemosa Chamisso, with hand-pollination experiments and the histology of post-pollination events. Flower anthesis lasted 1-3 days, and although the frequency of flower visitation was extremely low, natural pollination seemed to be effected mainly by medium-sized bees. Because the conspicuous staminodium favours eventual pollination by small bees, a possible role of the staminodium in the increase of potential pollinators is suggested. Hand-pollinations indicated that J. racemosa is a self-sterile species. Histological analysis of post-pollination events indicated the occurrence of a kind of late-acting self-incompatibility in which the processes of ovule penetration, fertilisation and endosperm initiation were slower in selfed than in crossed pistils. Until the time of self-pollinated pistil abscission, no signs of endosperm malfunction or proembryo development were observed in selfed pistils. Therefore, inbreeding depression is an unlikely explanation for self-sterility in J. racemosa.

TOURISM IN CAVES and THE CONSERVATION of THE SPELEOLOGICAL HERITAGE: THE CASE of SERRA da BODOQUENA (MATO GROSSO do SUL STATE, BRAZIL)

Heros Augusto Santos Lobo & Edvaldo Cesar Moretti: Tourism in Caves and the Conservation of the Speleological Heritage: The case of Serra da Bodoquena (Mato Grosso do Sul State, Brazil)The Serra da Bodoquena is the region in the state of Mato Grosso do Sul, Brazil in which the Municipality of Bonito is located. This municipality is the primary calling card for tourism in the state and is one of the most developed areas of ecotourism and speleotourism in the country The tourism there is entitled ecotourism, and is designed to be sustainable. The present case study focuses on the ecologically Sustainable aspects of the spleotourism practiced there, especially the proposals for tourist carrying capacity adopted. The results and discussion provide Suggestions for the adoption of a different formulation of carrying capacity focusing on both operational and quantitative aspects. Ecologically Sustainable speleotourism in the Serra da Bodoquena should be possible as long as new proposals limiting visitation are adopted which conform to technical environmental management procedures and consider the interests of local stakeholders.

Consumption of bottled water by children in the city of Bauru, State of São Paulo, Brazil - A brief communication

Objectives: To determine the consumption of bottled water by children in the city of Bauru, State of São Paulo, Brazil. Methods: A stratified sample of the 17 areas established by the city plan was used to identify a total of 1,000 homes for visitation. Information was collected using a questionnaire concerning the type of water consumed and population demographics. Results: Overall, around 30 percent of all residences used bottled water. Among all households where bottled water was consumed, about 26 percent had children residing. For those with children and bottled water, 81 percent reported to use bottled water for the preparation of the children's foods and beverages. Conclusions: An important percentage of children consume bottled water in the city of Bauru, State of São Paulo, Brazil. Considering previous studies showing that fluoride concentrations vary in bottled water, public health measures should be implemented in order to guarantee adequate levels of fluoride in commercialized water. © 2007, American Association of Public Health Dentistry.

Capacidade de carga real (ccr) da caverna de santana, parque estadual turístico do alto ribeira (Petar) - sp, e indicações para o seu manejo turístico

The tourist use of Santana cave provides a row of environmental damages, compromising partially the pristine conditions. Among the measures adopted to avoid this situation, this issue presents a contribution for the physical limits to tourist visitation and the indications for speleotouristic management. It was used the Cifuentes Carrying Capacity method and some basic principles of Visitors Impact Management Framework - VIM. The results show a Real Carrying Capacity (CCR) about 120 visits daily on the cave. The discussions raise a few hypotheses about the alteration in the method used and the temporal frequency between visitors groups, suggesting a provisional CCR of 117 and 135 visitors daily, respectively, during the week and in the weekends and holidays. The conclusions appoint the necessity of a conceptual revision in the Carrying Capacity methods, mainly about its adaptation for tourist management in caves. In the case studied, it is suggested the immediate beginning of environmental monitoring of the cave, to verify the plausibility from proposed visitation limits and the possible contributions for to mitigate the environmental impacts from speleotourism.

Differential seed germination of a keystone palm (Euterpe edulis) dispersed by avian frugivores

The effectiveness of seed dispersal by vertebrates has been analysed by examining both quantitative and qualitative components (Jordano & Schupp 2000, Schupp et al. 2010). While the quantitative component is relatively easily assessed in the field (e.g. visitation rate, number of fruits eaten per visit), the qualitative component (e.g. fate of dispersed seeds, seed treatment in the digestive system of the disperser) is rarely studied under natural conditions, because it is difficult to measure the effects on seeds once ingested by the dispersers (Cortes et al. 2009). © Cambridge University Press 2012.
