Modeling the ecology and evolution of biodiversity: Biogeographical cradles, museums, and graves [PDF]

, 2018
Individual processes shaping geographical patterns of biodiversity are increasingly understood, but their complex interactions on broad spatial and temporal scales remain beyond the reach of analytical models and traditional experiments.

Tropical forests and global atmospheric change: a synthesis [PDF]

, 2004
We present a personal perspective on the highlights of the Theme Issue 'Tropical forests and global atmospheric change'. We highlight the key findings on the contemporary rate of climatic change in the tropics, the evidence--gained from field studies--of

An interdisciplinary review of the interplay of conflict, socio‐economic factors, and land cover and vegetation dynamics in Colombia

PLANTS, PEOPLE, PLANET, EarlyView.
Colombia's forests play a crucial role in preserving biodiversity and mitigating climate change, but they are currently facing severe degradation, particularly after the 2016 Peace Agreement. Our literature review highlights a growing research interest in this topic and demonstrates how interdisciplinary approaches combining diverse methods can enhance

Molecular phylogeny and historical biogeography of the neotropical swarm-founding social wasp genus Synoeca (Hymenoptera: Vespidae). [PDF]

PLoS ONE, 2015
The Neotropical Region harbors high biodiversity and many studies on mammals, reptiles, amphibians and avifauna have investigated the causes for this pattern. However, there is a paucity of such studies that focus on Neotropical insect groups. Synoeca de

The onset of grasses in the Amazon drainage basin, evidence from the fossil record [PDF]

, 2020
Poaceae (the grass family) originated in the Cretaceous, but first dominate the palynological records of the Amazon drainage basin (ADB) in the Neogene (23 to 2.5 million years ago (Ma)).

Wall‐to‐wall Amazon forest height mapping with Planet NICFI, Aerial LiDAR, and a U‐Net regression model

Remote Sensing in Ecology and Conservation, EarlyView.
Tree canopy height is a key indicator of forest biomass and structure, yet accurate mapping across the Amazon remains challenging. Here, we generated a canopy height map of the Amazon forest at ~4.8 m resolution using Planet NICFI imagery and a deep learning U‐Net model trained with airborne LiDAR data.

Cryptosporidiosis outbreak in Amazonia, French Guiana, 2018.

PLoS Neglected Tropical Diseases, 2022
BackgroundCryptosporidiosis outbreaks in South America are poorly documented. In March 2018, 51 cases of cryptosporidiosis were reported in Maripasoula, a village located in a remote forest area along the border between Surinam and French Guiana.MethodTo

Perturbations in the carbon budget of the tropics [PDF]

, 2014
The carbon budget of the tropics has been perturbed as a result of human influences. Here, we attempt to construct a ‘bottom-up’ analysis of the biological components of the budget as they are affected by human activities.

Social, Technological, Economic, and Policy Factors in the Circular Economy Transition in Brazil

Sustainable Development, EarlyView.
ABSTRACT A well‐functioning circular economy (CE) integrates resilience across economic, environmental, and social dimensions. This study identifies key drivers and barriers to Brazil's CE transition through 20 semi‐structured interviews with stakeholders. Major sociocultural barriers include inadequate education and limited CE awareness, while growing
