Multitrophic relationships, conditional mutualisms, and the study of interaction biodiversity in tropical savannas
Provedor de dados: 82
Autores: Del-Claro,Kleber.
Biodiversity as a focus for conservation efforts has received increased attention since the second half of the last century. Until recently a more landscape-level view of biodiversity has prevailed. This essay proposes to discuss natural diversity in ways that embrace the extreme richness inherent in plant animal interactions, including not only trophic relationships, but also aspects of life history, biology, and behavior of related species. The ant-plant-herbivore systems in Cerrado vegetation are pointed out as good model for gaining a better understanding of "interaction biodiversity".

Anatomy, ultrastructure and secretion of Hibiscus pernambucensis Arruda (Malvaceae) extrafloral nectary
Provedor de dados: 88
Autores: Rocha,Joecildo Francisco; Machado,Silvia Rodrigues.
This paper reports on the extrafloral nectary (EFN) of Hibiscus pernambucensis, a native shrub species occurring in mangrove and restinga along Brazil's coastline. EFNs occur as furrows with a protuberant border on the abaxial surface veins of the leaf blade. Each nectary consists of numerous secretory multicellular trichomes, epidermal cells in palisade-like arrangements and non-vascularized parenchyma tissue. Nectar secretion is prolonged, since secretion starts in very young leaves and remains up to completely expanded leaves. Reduced sugars, lipids, and proteins were histochemically detected in all the nectary cells; phenolic substances were detected in the vacuoles of the epidermal palisade cells and in some secretory trichome cells. The secretory...
