Fonio (Digitaria exilis and Digitaria iburua) in Nigeria: Regional cultivation patterns, landrace diversity, and farmer knowledge for conserving a climate‐resilient indigenous cereal

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Fonio (Digitaria exilis and Digitaria iburua) cereals are valued for their drought resilience, adaptability to poor soils, and cultural importance. In Nigeria, where both species are cultivated, fonio has declined due to labor‐intensive processing, lower yields, and changing livelihood choices. By documenting 21 landraces (15 D. exilis and 6 D. iburua),

Niche‐tracking as a collecting method: Habitat‐targeted search strategies for taxon‐focused botany

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity science depends on more than collecting plants—it depends on how we search for them. Although GPS and digital maps have transformed fieldwork, they can also encourage repeated visits to the same easy‐to‐access sites, leaving other habitats and populations unknown to science.

Improved Cerrado Wetland Mapping Through Seasonal Moisture Metrics, Terrain Information and Semantic Segmentation

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...

The inadequacies of the steppic savanna classification system to describe the vegetation of the semi-arid Caatinga of Brazil [PDF]

open access: yesRodriguésia
The steppic savanna term was originally employed to classify a single type of tropical vegetation in Africa, but it has been expanded by the pioneering RADAMBRASIL authors and it is currently used to classify the vegetation of the Caatinga in ...

frontiermetrics: An R Package for Characterizing Deforestation Frontiers

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Deforestation frontiers are major drivers of biodiversity loss, carbon emissions, and ecosystem degradation, yet our understanding of how deforestation progresses in these frontiers is limited. We present frontiermetrics, an R package to quantify a range of metrics describing the speed, severity, and spatio‐temporal patterns of forest loss. The package

The Socio‐Economic Benefits of Communal Trophy Hunting in Africa: A Value Chain Perspective From Namibia

open access: yesSustainable Development, EarlyView.
ABSTRACT International concerns around the equitable distribution of income generated by communal trophy hunting tourism have raised questions about the industry's effectiveness in promoting rural livelihoods and nature conservation. We examine how communities in Namibia derive benefits from wildlife and explore local perspectives on fostering active ...
