ESTUDO DA VARIABILIDADE PLUVIOMÉTRICA NO EXTREMO NORTE DO ESTADO DE MATO GROSSO ENTRE OS ANOS DE 1990 A 1996

POLLINATOR FORAGING STRATEGY IN Galactia peduncularis (BENTH.) TAUB. (LEGUMINOSAE: PAPILIONOIDEA) IN THE PARQUE ESTADUAL DA SERRA DE CALDAS NOVAS BRAZIL The way the animals look for food is an important characteristic of their behavior. The optimal foraging theory is based on the existence of a balance between costs and benefits of these behavioral decisions. The present study aimed to evaluate the behavior of the pollinator in response to increased availability of floral resources. The experiment was conducted in a recently burned Cerrado area (Campo rupestre) in the State Park of Serra de Caldas Novas , located in the municipalities of Caldas Novas and Rio Quente Brazil. The species chosen to test our hypothesis was Galactia peduncularis (Benth.) Taub. (Leguminosae: Papilionoidea). 17 pairs of specimens were selected with a number of flowers, and the individuals of each pair were spaced by about 2m. In these pairs, one of them was considered the focal, and the other, the isolated. To test possible differences in pollination between isolated plants and focus, we performed two randomization tests: a test binary (TB), where all pairs were analyzed and verified the number of times where the focus on the individual floral visits were higher than the number of visits in isolated. According to the data analyzed, floral visitors preferred to use plants that could provide a greater amount of floral resources so that the number of visitors varied positively with the increment of flowers. Plants with many flowers can provide a greater amount of food in one location so that visitors do not need to flower around for long distances in search of meeting their energy needs.

Caracterização Geológica Ambiental do Distrito Afonsinho no Município de Alto Paraguai – MT

Este artigo esta baseado em estudos geologicos ambientais, realizados na area do Distrito Afonsinho, pertencente ao municipio de Alto Paraguai, situado na porcao Centro-Sul do Estado de Mato Grosso, e drenado pelo rio Paraguai. Aqui estao contidos resultados obtidos em trabalhos de campo e de gabinete, realizados tendo como objetivo maior a questao ambiental dentro da otica de um levantamento geologico ambiental regional na escala 1:100.000. Dentro deste pensamento foram evidenciados os aspectos mais significativos no que tange a estes estudos, onde foram determinados os recursos naturais, associados com as caracteristicas climaticas, a geologia regional, a compartimentacao geomorfologica, os solos, a hidrografia e a cobertura vegetal. Esses dados estao associados com os resultados dos trabalhos de campo do mapeamento em questao, e de estudos laboratoriais que nos conduziram a edificacao de um mapa geoambiental. Estao contidos nesta descricao alguns topicos que consideramos importantes a fim de ilustra-la e enfatiza-la.
