Expansão urbana e variações mesoclimáticas em João Pessoa, PB

A cidade de Joao Pessoa, na Paraiba, vem sendo submetida, nos ultimos anos, a um forte crescimento urbano. Nesse contexto, este trabalho verificou entre as decadas de 1980 e 2000 variacoes climaticas significativas que possam ser correlacionadas com o crescimento urbano. Para tanto, utilizaram-se imagens de satelite nos anos de 1977 e 2009 para o calculo da area edificada, bem como foram utilizadas series de dados das variaveis climaticas: precipitacao pluviometrica e temperatura do ar, colhidas em duas estacoes instaladas na malha urbana, e uma terceira, tomada como estacao de referencia, fora da malha urbana. Para a caracterizacao do crescimento da cidade, utilizaram-se dados quantitativos da populacao residente constantes dos censos demograficos de 1872 a 2009. Para a verificacao do ritmo do comportamento da serie temporal de temperatura e precipitacao foram gerados graficos da temperatura media e do acumulado mensal dos meses correspondentes aos trimestres mais quentes e menos quentes do periodo de 1984 a 2008. Dos resultados obtidos do tratamento e analise dos dados pode-se verificar que a temperatura do ar da cidade aumentou nos ultimos 26 anos, havendo-se detectado que as temperaturas do ar sofreram elevacoes mais expressivas nos meses do trimestre mais quente, fato que pode ser correlacionado com a expansao da malha urbana.

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.
