Hummingbird-Pollinated Floras at Three Atlantic Forest Sites1
Abstract We studied 86 species of hummingbird-pollinated flowers and their pollinators at a coastal lowland site and two highland rain forest sites in southeastern Brazil. The Jaccard index for
The results indicate that early lanceheads were probably stout, terrestrial forest dwellers that fed on a variety of prey, and the generalist diet of early Bothrops may have facilitated some of the ecological shifts described here and the great diversification that occurred in the genus in South America.
Behavioural defences of anurans: an overview
The role of predators in the evolution of defensive behaviours is still scarcely touched upon and this overview adds data to explore this and other evolutionary unsolved questions.
Bat-pollinated Flower Assemblages and Bat Visitors at Two Atlantic Forest Sites in Brazil
A comparison between bat-pollinated plant assemblages at two sites in different altitudinal ranges covered by the Atlantic rainforest in southeastern Brazil is presented, finding similar values indicate that additional studies on bat- and bird- pollinated assemblaged species are merited at other AtlanticRainforest sites.
Similarities in feeding behaviour between some marine and freshwater fishes in two tropical communities
The picture emerged that different, unrelated fish assemblages have the ability to evolve towards a similar behavioural and structural organization in response to comparable situations and constraints.

SynopsisScale-eating is known for several unrelated fish groups, but few data are available on the habits of most species. General habits and feeding behavior of some lepidophagous characoids are
The snake assemblage of the Pantanal at Poconé, Western Brazil: Faunal composition and ecological summary
The faunal composition and ecological features were studied in a snake assemblage in the Pantanal, an open and seasonally flooded area in western Brazil. Twenty six species of snakes in 19 genera and
Amphibian Declines in Brazil: An Overview 1
Records suggest declines of montane and stream‐associated populations of Brazilian amphibians in apparently pristine habitats, and it is important to invest in short‐ and long‐term field studies, and in the maintenance and expansion of museum collections.
The nested structure of marine cleaning symbiosis: is it like flowers and bees?
The results support the notion that mutualisms evolve to a predictable community-level structure, be it in terrestrial or marine communities.
Is it all death feigning? Case in anurans
It is believed that there is more than one behaviour type referred to as thanatosis, and definitions and new names that complement the present knowledge on the subject are proposed.
