Comportamento de forrageamento do pernilongo-de-costas-brancas, Himantopus melanurus (Vieillot, 1817) (Aves: Recurvirostridae) em Santa Gertrudes, SP, Brasil

The foraging behavior of two White-backed stilts (Himantopus melanurus) was studied in a lake at the municipality of Santa Gertrudes, state of São Paulo, Brazil. The foraging strategies observed were classified in two categories: pluging (65.8% of total maneuvers) and pecking (34.3%). Only in 26.8% of the foraging maneuvers the individuals captured preys (72.9% by plunging and 27.1% by pecking). When comparing both strategies, plunging was successful 29.7% of the times, but pecking only 21.2%. At the study site, individuals foraged only up to 20 m away from the lake margin. The foraging area exploited by the White-backed stilts was estimated in about 720 m 2. Foraging activities lasted since before sunrise until after sunset. © 2006 Instituto de Ciências Biológicas - UFMG.

Análise da técnica dos estilos Crawl e Costas em praticantes de natação

The aim of this study was to analyze and evaluate the performance of swimmers tied to the Extension Project Natação na UNESP at distances of 25m, 50m, 75m and 100m. The study included 20 people, including 12 men and 8 women. From an aerial footage was possible to record the tests proposed by the analysis of videos of, Freestyleand Backstroke styles for stroke cycles, average speed, stroke frequency and time proof stretches of 0-25m, 25-50m, 50-75m e 75-100m. Thus, it was possible to calculate stroke length, frequency, average speed as proposed in the study of Maglischo (1999). From these data were applied to descriptive statistics with mean and standard deviation, minimum and maximum scores in the different parameters of analysis and statistical tests, t-test and correlation to make comparisons between styles and between the distances swims by the subjects. Regarding the performance of the participants in the eight proposed tests, it can be said that most have already mastered the styles Crawl and Back Crawl for having managed to finish the tests proposed. However, the results of the variables analyzed mainly by the total time obtained in the tests can classify the subjects in the initial phase of learning and to start the training will be necessary to improve the implementation of styles
