Mapping the density of giant trees in the Amazon [PDF]

New Phytologist, Volume 249, Issue 1, Page 152-168, January 2026.
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

Forest citizens and people‐centered conservation in the Brazilian Amazon [PDF]

Conservation Biology, Volume 39, Issue 3, June 2025.
Abstract Demands for territorial recognition are foundational to the claiming of rights by forest‐proximate people who attempt to conserve their forests. The rights of these often‐marginalized populations have been largely overlooked by conservationists, yet they are central to achieving people‐centered conservation. We further developed the concept of

Including the urbanization gradient in people‐centered wildlife conservation in Amazonia [PDF]

Conservation Biology, Volume 39, Issue 3, June 2025.
Abstract Conservation policy in the Amazon traditionally focuses on rural areas, overlooking the socioecological roles of urban populations. This oversight can hinder sustainability by neglecting rural–urban connections. We compared the prevalence and quantity of wild meat consumed, bartered, and traded commercially in rural, peri‐urban, and urban ...

Scale dependency of conservation outcomes in a forest‐offsetting scheme [PDF]

Conservation Biology, Volume 34, Issue 1, Page 148-157, February 2020., 2020
Abstract Offset schemes help avoid or revert habitat loss through protection of existing habitat (avoided deforestation), through the restoration of degraded areas (natural regrowth), or both. The spatial scale of an offset scheme may influence which of these 2 outcomes is favored and is an important aspect of the scheme's design.

Enhancement of conservation knowledge through increased access to botanical information [PDF]

Conservation Biology, Volume 33, Issue 3, Page 523-533, June 2019., 2019
Abstract Herbarium specimens are increasingly recognized as an important resource for conservation science and virtual herbaria are making specimens freely available to a wider range of users than ever before. Few virtual herbaria are designed with conservation use as a primary driver. Exceptionally, Brazil's Reflora Virtual Herbarium (RVH) was created
