Variation in aboveground tree live biomass in a central Amazonian Forest: Effects of soil and topography
We used forest inventories, conducted in seventy-two 1-ha permanent plots to assess the variation in tree and palm aboveground live biomass (AGLB), and its relation with soil gradients (texture andExpand

RAPELD: A MODIFICATION OF THE GENTRY METHOD FOR BIODIVERSITY SURVEYS IN LONG-TERM ECOLOGICAL RESEARCH SITES.
Our objectives were to develop a method that would be appropriate for long-term ecological studies, but that would permit rapid surveys to evaluate biotic complementarity and land-use planning inExpand

Acoustic interference and recognition space within a complex assemblage of dendrobatid frogs
In species-rich assemblages of acoustically communicating animals, heterospecific sounds may constrain not only the evolution of signal traits but also the much less-studied signal-processingExpand

Diets of Amazonian Crocodilians
Differences in diets among Amazonian crocodilians can largely be related to habitat selec- tion. Caiman crocodilus, Melanosuchus niger and Paleosuchus palpebrosus, which occur around rivers and lakesExpand

Gradients within gradients: The mesoscale distribution patterns of palms in a central Amazonian forest
Questions: What are the relative contributions of environmental factors and geographic distance to palm community structure at the mesoscale, and how do they depend on the length of the environmentalExpand

A NEW AMAZONIAN SPECIES OF COLOSTETHUS (ANURA: DENDROBATIDAE) WITH A NIDICOLOUS TADPOLE
We describe adults, tadpoles, and vocalization of a new Amazonian species of Colostethus from a terra firme rainforest locality south of the Amazon River near Manaus, Amazonas, Brazil. This speciesExpand

MASKING INTERFERENCE AND THE EVOLUTION OF THE ACOUSTIC COMMUNICATION SYSTEM IN THE AMAZONIAN DENDROBATID FROG ALLOBATES FEMORALIS
The efficacy of communication relies on detection of species-specific signals against the background noise. Features affecting signal detection are thus expected to evolve under selective pressuresExpand

Calls, colours, shape, and genes: a multi-trait approach to the study of geographic variation in the Amazonian frog Allobates femoralis
Evolutionary divergence in behavioural traits related to mating may represent the initial stage of speciation. Direct selective forces are usually invoked to explain divergence in mate-recognitionExpand

Effects of prey size and foraging mode on the ontogenetic change in feeding niche ofColostethus stepheni (Anura: Dendrobatidae)
The feeding niche ofColostethus stepheni changes during ontogeny. Small individuals eat small arthropods, principally mites and collembolans, and larger frogs eat bigger prey of other types. TheExpand
