1. Beef cattle performance on signal grass pastures deferred and fertilized with nitrogen
RESUMO Foi avaliado o efeito de quatro doses de nitrogênio (0, 40, 80 e 120kg N ha -1 ), aplicadas antes do diferimento, sobre o desempenho de bovinos e as características estruturais de Urochloa decumbens (capim-braquiária), de janeiro a outubro de 2012 e de janeiro a setembro de 2013. Um delineamento de blocos ao acaso foi utilizado em arranjo de medid

2. Exploring the Insecticide and Acaricide Potential of Development Regulators obtained from Restinga vegetation from Brazil
Abstract: As a part of our continuing search for insect and arthropod development regulators from Brazilian restinga vegetation of the Rio de Janeiro State, crude extracts, purified fractions and essential oils were submitted to screening tests seeking for biological activities on the development of the insects Rhodnius prolixus, Dysdercus peruvianus, Oncope

3. The role of condensed tannins in ruminant animal production: advances, limitations and future directions
ABSTRACT Tannins represent one of the most abundant polyphenolic compounds in plants. Tannins exist as a multitude of chemically unique entities in nature. The most commonly occurring tannins are typically divided into two major classes based on chemical structure: hydrolysable (HT) or condensed tannins (CT). Hydrolysable tannins are esters of gallic or ella

4. Variation in plant-animal interactions along an elevational gradient of moist forest in a semiarid area of Brazil
Pollination and dispersal are critical ecological processes that directly affect the reproductive success of plants and are important for understanding the structure of plant communities. We compiled data on pollination and dispersal syndromes of 406 plant species distributed among different elevations in Área de Proteção Ambiental da Serra de Baturité (

5. Diversidade e frugivoria por morcegos em um remanescente de floresta semidecidual de Uberlândia, MG / Diversity and frugivory by bats in a semidecidual forest remnant from Uberlândia, MG
Em ambientes tropicais, os morcegos podem representar mais de 50% da composição da comunidade de mamíferos. A importância destes animais, entretanto, vai muito além da sua grande contribuição para a biodiversidade. Eles apresentam também alta diversidade em suas funções ecológicas: são vetores de doenças de importância médica-veterinária, red

6. Distribuição espacial e temporal de placas de esterco e produtividade da soja em sistema de interação soja-bovinos de corte / Spatial and temporal distribuition of dung and soybean yield in integrated soybean-beef cattle system
This study was conducted at Planalto Médio region, RS, in the experimental protocol of long duration, between July 2010 and April 2011, consisting of two experiments. In Experiment 1 it was realized samples of dung, in intervals of 20 days in each treatment of sward height (10, 20, 30 and 40 cm). Six evaluations were amounted from that period have been mark

7. Evolução e ecologia de tricomas em Bignonieae (Bignoniaceae): estruturas morfológicas de defesa anti-herbivoria? / Evolution and ecology of trichomes in Bignonieae (Bignoniaceae): morphological structures of anti-herbivory defense?
This thesis focused on the evolutionary-ecology of trichomes in the tribe Bignonieae (Bignoniaceae), and in the potential defensive role of these structures against herbivores. More specifically, we characterized four trichome morphotypes found in vegetative plant parts of representatives of the Bignonieae, as well as studied the macro-evolutionary patterns

8. Analgesic effect of leaf extract from Ageratina glabrata in the hot plate test
Ageratina glabrata (Kunth) R.M. King & H. Rob., Asteraceae (syn. Eupatorium glabratum Kunth) is widely distributed throughout Mexico and popularly known as "chamizo blanco" and "hierba del golpe" for its traditional use as external analgesic remedy. Though glabrata species has been chemically studied, there are no experimentally asserted reports about possib

9. Forage mass production and grazing loss of sorghum hybrid in response to the density of the sowing and the spacing between planting lines
The objective of this experiment was to evaluate dry matter yield and loss of grazing due to animal trampling in response to sowing density and spacing between lines in the planting. Sorghum hybrid 1P400 was submitted to six treatments, composed of three sowing density combinations (12; 16 and 20 kg/ha of seeds) and two spacing between lines (0.40 and 0.80 m

10. Interações ecológicas em Malpighiaceae no cerrado: compartilhamento de guildas de herbívoros e variações nos resultados da interação formiga-planta / Ecological interactions in Malpighiaceae in the Cerrado: sharing of guilds from herbivores and variations in the results of ant-plant interaction
Ecological interactions represent essential tools for a better understanding of natural communities, having in animal-plant relationships important models for study. For that, become needful phenological analyses of plants, capable of demonstrating the flowering strategies and with it the ways of temporal organization of resources available for herbivores. T

11. Crescimento vegetativo, produÃÃo e composiÃÃo quÃmico-bromatolÃgica da palma forrageira consorciada com cajà (Spondias spp) / Vegetative growth, production and chemical composition of cactus pear intercroppedwith caja (Spondias spp)
In the Brazilian Northeast the efficiency of the animal production was increased when combining native pastures and grass adapted in consequence of the low productivity of the native grass, mainly at that time of drought. The importance of the forager palm as one of the most important grass, for your high productivity and quality for the ruminant. However, t

12. História natural e interação flores-besouros em espécies de Cerrado / Natural history and flower-beetle interactions in Cerrado species
Plant-animal interactions, such as pollination, are a key element in many terrestrial communities. The study of who interacts with whom is an important approach for understanding ecological and evolutionary processes. In some tropical communities, up to one quarter of all plant species may be pollinated by beetles. They are an ancient and much diversified in
