Abstract Parrots (Order Psittaciformes) are secondary cavity-nesters that depend on existing
cavities for nest sites, and consume plant resources of fruits, seeds, and flowers that are …

Mauritia flexuosa is a key ecological and economic palm found throughout tropical South
America. To inform improved management of M. flexuosa, we conducted a systematic review …

Climate change is affecting biodiversity and ecosystem function worldwide, and the lowland
tropics are of special concern because organisms living in this region experience …

We document patterns of fruit and vertebrate abundance within an extensive, virtually
undisturbed mosaic of seasonally flooded (várzea and igapó) and unflooded (terra firme) …

Parrots that inhabit tropical lowland forests are difficult to study, are poorly known, and little
information is available on their nesting habits, making analysis of community-wide nesting …

We examined seasonal patterns of spatial variation in understory bird assemblages across a
mosaic of upland and floodplain forests in central Amazonia, where variation in flooding …

River system dynamics results in ecological heterogeneities that play a central role in
maintaining biodiversity in riverine regions. In central Amazonia, large expanses of forest …

Estimates of population density and abundance change (differences in density or encounter
rates across land uses or time periods) form the cornerstone of much of our knowledge of …

Habitat spatial distribution, seasonal variation, and activity patterns influence changes in
vertebrate assemblages over time. Terrestrial birds play major roles in the dynamics of …

The Military Macaw (Ara militaris) is an endangered species with a fragmented distribution
and declining populations. Their diet has not been described in detail but the species is …
