Balanço de energia na cultura de pepineiro em ambiente natural e protegido

Avaliaram-se, diariamente, neste trabalho, o saldo de radiação (SR), o fluxo de calor no solo (G), o fluxo de calor latente de evaporação (LE) e o fluxo de calor sensível (H) ao longo do ciclo da cultura de pepineiro cultivado dentro e fora de casa de vegetação em ciclo de outono-inverno e primavera-verão. O SR e o G foram quantificados e o LE e o H estimados em dois níveis distintos pelo método da razão de Bowen. Os resultados mostram que a maior parte da energia disponível foi utilizada no fluxo de calor latente de evaporação e que os componentes do balanço de energia apresentaram-se mais consistentes em níveis próximos ao dossel da cultura e em ambiente protegido.

Número e tamanho dos recém-nascidos de Hippocampus reidi em ambiente natural

Four births of Hippocampus reidi Ginsburg, 1933 were monitored for the first time under natural conditions. This study provides the fish estimate of fecundity in the wild, which is an important parameter for assessing population dynamics and management strategies.

Diferentes percepciones de un mismo ambiente: la cuestión del género en la enseñanza de la ciência

This paper relates some considerations resulting from a thesis study in Biological Sciences held at Universidade Estadual Paulista - Unesp, Bauru Campus. Considering the perceptual act endowed with simultaneous actions of the cognitive apparatus and the individual's life history as the merleau-pontyana phenmomenon tells us, the work aimed to identify how boys and girls in elementary school realize a natural savanna. The study was realized with the extension project "Walking and learning at the cerrado” in the Center for Memory and Dissemination of Science and Technology (CDMCT) of Postgraduate Education for Science in the same institution. Classes were held in these practical activities, monitored by undergraduate and graduate students, and, the project focuses on students from public and private schools in Bauru and region, and other visiting groups. Data collection was performed using the representations in the form of free drawings of students of their environment after the activity. Through qualitative and quantitative analysis, the results allowed us to highlight differences in the way in which genders perceived and thus represented the fragment of cerrado vegetation. The male drawings contained a larger amount of non-living elements, whereas the representations by women, besides their botanical details, often drew on animals and people. The framework of the drawings by the boys took the nearest way, whereas by the girls more often considered the representations and the entire context of the site visited. So, we emphasize the need for further discussions within the perception of the environment to consider differences in the representations of boys and girls within the context of the teaching of natural sciences, seeking, however, to avoid unsubstantiated preconceptions that may cause any degree of discrimination.
