Abstract Ecological restoration aims to retrieve not only the structure but also the functionality of ecosystems. Frugivorous birds may play an important role in this process due to their efficiency in seed dispersal. Color perception in these animals is highly developed, and then the colors of fleshy fr...
Abstract The goal of this study was to identify which bird species consume Solanum granuloso-leprosum fruits and disperse its seeds. 60 hours of focal observations were carried out between April and May 2006 on the edge of a deciduous forest fragment in the Uruguay River region, Rio Grande do Sul state, ...
Abstract Local knowledge of biodiversity has been applied in support of research focused on utilizing and management of natural resources and promotion of conservation. Among these resources, Pequi (Caryocar brasiliense Cambess.) is important as a source of income and food for communities living in the C...

AbstractPlants have limited resources to invest in reproduction, vegetative growth and defense against herbivorous. Trade-off in resources allocation promotes changes in plant traits that may affect higher trophic levels. In this study, we evaluated the trade-off effect between years of high and low frui...
AbstractIn any ecosystem, fruits are resources that vary in time and space as well as in nutritional content. Coexistence of species from a trophic guild depends on the division and use of resources. Therefore, the organisms that depend on them as a food source, tend to show a certain degree of specializ...
The increase in Equus africanus asinus Linnaeus population in semiarid areas of Northeast Brazil had significant impacts on wild and rural areas. The objective of this work was to analyze the herbivory of E. africanus asinus on Poincianella pyramidalis (Tul). L.P. Queiroz and determine the dendrophysiolo...

BACKGROUND: Essential oils extracted from aromatic and medicinal plants have many biological properties and are therefore an alternative to the use of synthetic products. The chemical composition of essential oils from two medicinal plants (Eucalyptus globulus and E. lehmannii) was determined and, their ...
