1. Ecology of interactions between ants and plants with extrafloral nectaries in a neotropical savanna: temporal variation in the network of interactions and their effects on leaf herbivory / Ecologia das interações entre formigas e plantas com nectários extraflorais em uma savana neotropical: variação temporal na rede de interações e seus efeitos sobre a herbivoria foliar
Estudos de interações envolvendo formigas e plantas com nectários extraflorais são comuns na literatura, entretanto, devido à grande diversidade de espécies envolvidas e à variação nos resultados das interações, pouco se conhece a respeito da dinâmica e estrutura dessas relações no âmbito da comunidade. Dessa forma, este estudo propôs avaliar

2. Ecologia trÃfica de Rhinella hoogmoedi Caramaschi e Pombal, 2006 (Anura, Bufonidae) em uma floresta Ãmida do estado do CearÃ, Brasil / Trophic ecology of Rhinella hoogmoedi Caramaschi e Pombal, 2006 (Anura, Bufonidae) in a humid forest in the State of CearÃ, Brazil.
The understanding of trophic relations among species is essential for the comprehension of their ecological evolutionary history, as well as in the understanding of how communities are structured. The consumption of the same food resource by two or more species may result in the evolution of mechanisms capable of reducing this inter- specific competition, wi

3. AlocaÃÃo de recursos com justiÃa: uma aplicaÃÃo de jogos cooperativos em redes de computadores
This work presents a methology for applying cooperative game theory concepts for solving the bandwidth allocation problem within differentiated traffic profiles for Internet applications. The multi-service networks scenario is explored as an operational network example for fair bandwidth sharing mechanisms. This operational network uses mechanisms based on s

4. An organizational field approach to resource environments in healthcare: comparing entries of hospitals and home health agencies in the San Francisco Bay region.
OBJECTIVE: To draw together insights from three perspectives (health economics, organizational ecology, and institutional theory) in order to clarify the factors that influence entries of providers into healthcare markets. A model centered on the concept of an organizational field is advanced as the level of analysis best suited to examining the assortment a

5. On the advantage of being different: Nest predation and the coexistence of bird species
A long-standing debate in ecology centers on identifying the processes that determine which species coexist in a local community. Partitioning of resources, where species differ in resource use, is often thought to reflect the primary role of competition in determining coexistence of species. However, in theory predation can favor similar patterns. This theo
