Social vulnerability, risk and disaster perceptions: concepts and approaches in/from the urban context

urbanization process observed mainly in larger cities, and imply risk and vulnerability situations that can materialize as disasters. In this scenario, researchers’ worries are turning to studies that contribute to the implementation of policies that aim to reduce or relieve the risks of these populations’ everyday lives, as well as their vulnerabilities. Hence, the present study proposes a discussion about the conceptual aspects concerning risk, social vulnerability and disaster, and how they are correlated, also aiming to clarify the misconceptions that permeate this theme. It also stresses the importance of risk perception in the urban context as an important tool in risk reduction, thus aiming to contribute with theoretical questions that involve this emerging science, risk studying, which is so important to our daily lives, as well as to people’s life quality in the future.

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.
