1. Foraging behavior interactions between the invasive Nile Tilapia (Cichliformes: Cichlidae) and three large native predators
RESUMO As relações predador-presa entre alevinos de Tilápia-do-Nilo Oreochromis niloticus e espécies de peixes nativos da bacia do rio Paraná, Brasil, foram examinadas experimentalmente. Dez alevinos de O. niloticus foram oferecidos a três espécies nativas de predadores (Salminus brasiliensis, Pseudoplatystoma corruscans e Brycon orbignyanus) em tanqu

2. What is on the menu for frugivorous birds in the Cerrado? Fruiting phenology and nutritional traits highlight the importance of habitat complementarity
ABSTRACT The relationship between plants and frugivorous animals is modulated by morphological and nutritional characteristics of fruits, as well as their seasonal availability across habitats. We evaluated fruiting phenology, fruit morphology and nutritional characteristics of 35 abundant plant species from 15 families associated with frugivorous birds from

3. Habitat complexity does not influence prey consumption in an experimental three-level trophic chain
RESUMO A complexidade de habitat influencia a diversidade de espécies e regula interações tróficas, principalmente por possibilitar a partição de recurso nos habitats e fornecer refúgio para presas. A influência da complexidade de habitat sob mais de dois níveis tróficos não é bem compreendida, especialmente porque modificações comportamentais

4. Together yet separate: variation in soil chemistry determines differences in the arboreal-shrub structure of two contiguous rupestrian environments
ABSTRACT Rupestrian landscapes are characterized by vegetation mosaics comprised of different plant communities and strongly linked to environmental filters. These environments are nutrient-impoverished, and possess water retention deficits and high solar exposure. This study aimed to determine whether chemical properties of the soil shape the arboreal-shrub

5. Relating flight initiation distance in birds to tropical dry forest restoration
ABSTRACT Flight initiation distance (FID), defined as the distance at which an individual flees from an approaching predator, might depend on how the individual perceives the risk of being predated. Using a standardized walking approach method on focal bird individuals, we investigated whether different levels of vegetation cover (habitat) influence the perc

6. Tree legumes: an underexploited resource in warm-climate silvopastures
ABSTRACT Tree legumes are an underexploited resource in warm-climate silvopastures. Perceived benefits of tree legumes include provisioning (browse/mast, timber, fuel, human food, natural medicines, and ornamentals), regulating (C sequestration, greenhouse gas mitigation, soil erosion control and riparian buffers, shade, windbreaks, and habitat for pollinato

7. Effects of changes in the riparian forest on the butterfly community (Insecta: Lepidoptera) in Cerrado areas
ABSTRACT Preserved riparian vegetation usually has greater environmental complexity than the riparian vegetation modified by human actions. These systems may have a greater availability and diversity of food resources for the species. Our objective was to evaluate the effect of changes on the structure of the riparian forest on species richness, beta diversi

8. Variation of amphipod assemblage along the Sargassum stenophyllum (Phaeophyta, Fucales) thallus
ABSTRACTThe spatial distribution of fauna associated to marine macroalgae has mostly been investigated considering a horizontal plane. However, the macroalgal substrates can present a three-dimensional structure. In this sense, investigating how the associated fauna varies throughout a vertical plane can contribute to understanding the distribution of these

9. Parasitoids of the endangered leafcutter ant Atta robusta Borgmeier in urban and natural areas
Parasitoids of the endangered leafcutter ant Atta robusta Borgmeier in urban and natural areas. Hosts of parasitoids in urban areas may suffer from a double threat of habitat destruction by urbanization and parasitism pressure. Moreover, the parasitoids themselves might be at risk if they are specialists. Here, we studied whether Atta robusta (Hymenoptera, F

10. Padrões no uso do espaço arbóreo e terrestre por pequenos mamíferos não voadores em uma área de floresta com araucária do Rio Grande do Sul, Sul do Brasil
Neste estudo investiguei os padrões de uso do espaço arbóreo e terrestre por pequenos mamíferos não-voadores em diferentes estratos florestais em uma área de floresta com araucária (domínio da Mata Atlântica) localizada em São Francisco de Paula sul do Brasil. Os espécimes foram capturados, marcados e recapturados em quatro amostragens, cada uma c

11. Biotic factors and occurrence of Lutzomyia longipalpis in endemic area of visceral leishmaniasis, Mato Grosso do Sul, Brazil
The relationships between environmental exposure to risk agents and health conditions have been studied with the aid of remote sensing imagery, a tool particularly useful in the study of vegetation cover. This study aims to evaluate the influence of environmental variables on the spatial distribution of the abundance of Lutzomyia longipalpis and the reported

12. Distribuição e uso de habitat por peixes recifais e sua relação com a complexidade ambiental no arquipélago Fernando de Noronha, Nordeste do Brasil.
Reef environments are amongst the most diverse ecosystems in the world. Many studies attempting to explain the mechanisms which influence reef fish distribution and the factors responsible for high species diversity in these environments were accomplished in the last decades, but much controversy still exists and more information is, therefore, necessary.
