Trade-offs Between Water Transport Capacity and Drought Resistance in Neotropical Canopy Liana and Tree Species [PDF]

, 2016
In tropical forest canopies, it is critical for upper shoots to efficiently provide water to leaves for physiological function while safely preventing loss of hydraulic conductivity due to cavitation during periods of soil water deficit or high ...

Bushmeat consumption frequency and preferences among rural households in a West African savanna landscape: Implications for food security and conservation

People and Nature, EarlyView.
Abstract The drivers of consumer demand for bushmeat are relatively well studied in tropical forest systems, but much less so in savanna areas. This is important because differing ecological and socio‐economic conditions lead to different factors affecting the relationship between local communities and their natural resources.

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

People 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 ...

Divergent drivers of leaf trait variation within species, among species, and among functional groups. [PDF]

, 2018
Understanding variation in leaf functional traits-including rates of photosynthesis and respiration and concentrations of nitrogen and phosphorus-is a fundamental challenge in plant ecophysiology. When expressed per unit leaf area, these traits typically

The visible and invisible drivers of biocultural loss in the Amazon

People 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

Polymer 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 ...
