The relationship between Indigenous Peoples' lands and conservation: A systematic literature review

open access: yesPeople and Nature, EarlyView.
Abstract A growing body of peer‐reviewed literature is focused on the relationship between Indigenous Peoples' lands (Indigenous lands) and conservation outcomes. We performed a systematic review of this English reported peer‐reviewed literature (n = 111) to examine: the key characteristics; the conservation outcomes documented; the methods used in ...

The visible and invisible drivers of biocultural loss in the Amazon

open access: yesPeople and Nature, EarlyView.
Abstract The Amazon is rapidly approaching an ecological tipping point driven by deforestation, forest degradation and global climate change. These are visible issues that receive increasing political and public attention. However, the accelerating biocultural loss in the Amazon, including the extinction of Indigenous languages, the disruption of ...

Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

open access: yesPolymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

Wild dogs at stake: deforestation threatens the only Amazon endemic canid, the short-eared dog (Atelocynus microtis) [PDF]

open access: yes, 2020
The persistent high deforestation rate and fragmentation of the Amazon forests are the main threats to their biodiversity. To anticipate and mitigate these threats, it is important to understand and predict how species respond to the rapidly changing ...

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

open access: yesPLANTS, 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

Increasing dominance of large lianas in Amazonian forests [PDF]

open access: yes, 2002
Ecological orthodoxy suggests that old-growth forests should be close to dynamic equilibrium, but this view has been challenged by recent findings that neotropical forests are accumulating carbon and biomass, possibly in response to the increasing ...
