Bird species of black water inundation forests in the Jau National Park (Amazonas state, Brazil): their contribution to regional species richness

We compared the relative contribution of blackwater inundation forest (igapo) and unflooded (terra firme) forest for regional bird species diversity in the lower Rio Negro region. For analyses of habitat preference we used mist-net samples and an unpublished bird species check-list. The igapo forest had lower bird species diversity than the terra firme forest. However, some 14% of the forest bird species in the region are restricted to igapo forest. Species composition was found to be distinct between the understories of the two forest types. Common forest bird guilds in the Neotropics such as ant-following birds avoid igapo forest. The differential habitat selection among birds in the inundated and unflooded forest is likely to result from vegetation structure and biological interactions such as aggressive behaviour. Since the inundated forest has a typical biota, conservation efforts needs to be directed to protect these habitats. Unfortunately, inundation forests are threatened by several human actions, especially dam construction. The extent of protected areas in the Brazilian Amazon is insufficient for the adequate protection of the inundated habitats, because it includes only 3% of the total area.

Relações entre força muscular e composição corporal e regional em idosos

Exercise, in general have the ability to promote health, reduce loss of physical fitness, reduce declines in body composition and prevent disease, and promote improvements in athletic performance, and that's consensual today. Through analysis of body composition and physical fitness, you can diagnose the possible individuals at risk of developing diseases, and fractures caused by falls in the elderly. The DXA tests were used (densitometry by dual beam X-ray) to assess body composition and regional, 1 RM test to evaluate the maximum strength and girth measurements, diameters and skin folds in order to analyze the balance of power muscle with both body composition as regional. The results showed that the variance in bone mass between older content related to the change in the maximum muscular strength of the upper and lower limbs, but the force values are not related to increased muscle mass. The development of muscle strength fulfills a dual function in aging which is to maintain or reduce the rate of loss of lean body mass, and also so the body bone health
