Filtração de partículas através do dossel de uma floresta tropical úmida

Boletim do Museu Paraense Emílio Goeldi - Ciências Naturais, 2014
Understanding the dinamics of filtration of pollen and spores by plant canopies is crucial to the in the modelling of their dispersal, yet few studies have quantified filtration. Here, we examine the decline in the density of flour particles descending through a 40 m-tall tropical canopy on a windless day at Caxiuanã National Forest, Pará, Brazil ...

Open‐land‐derived agroforestry and effects of abandonment of management of the main crop on ecosystem services and woody plant diversity

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1805-1816, September 2026.
Tropical forests are rapidly declining. One promising strategy to reverse the loss of tropical forest is the establishment of agroforestry on open land. We combined interviews with biodiversity surveys to learn general lessons from success and nonsuccess stories of the establishment of open‐land‐derived coffee agroforests in one of the world's ...

Guild‐Specific Frog Responses to Natural Habitat Structure Gradients in an Atlantic Forest Mosaic

Ecological Research, Volume 41, Issue 5, September 2026.
This study investigated how habitat structure gradients are associated with frog species richness and occupancy in a naturally heterogeneous Atlantic Forest mosaic. We found that frog richness and occupancy patterns varied among ecological guilds and were highest in sites associated with lower values of the habitat structure gradient, which also ...

Biogeographic Disconnect and Biotic Homogenization in the Heart of the Amazon: Dominance of Exotic Species in Urban Trees

Biotropica, Volume 58, Issue 5, September 2026.
Exotic taxa dominate the urban woody flora, with potentially invasive species posing a direct risk to adjacent primary forest remnants. Historical management has favored a simplified, cosmopolitan species pool over regional biodiversity. There is failure to implement local native‐priority mandates, offering concrete ecological targets for urban ...

Oro‐Facial Contact Behaviors in Wild White Bald‐Headed Uakaris (Cacajao calvus): First Documentation of Direct Facial Contact and Facial Investigation in Pitheciidae

Biotropica, Volume 58, Issue 5, September 2026.
We document the first instances of direct oro‐facial contact and facial investigation in wild Cacajao calvus. These rare observations expand the social repertoire of Pitheciidae, suggesting that close‐range tactile communication complements the visual signaling of their distinctive red faces.

Human Disturbances and Woody Flora Diversity Along a Caatinga–Brejo de Altitude Gradient in Northeastern Brazil

Biotropica, Volume 58, Issue 5, September 2026.
ABSTRACT Tropical dry forests are among the ecosystems most threatened by human activities worldwide. The Caatinga, a seasonally dry tropical forest restricted to northeastern Brazil, exemplifies this scenario, as local human populations strongly depend on forest resources.
