Butterfly and moth habitat specialisation changes along an elevational gradient of tropical forests on Mount Cameroon

open access: yesOikos, EarlyView.
Niche breadth, reflecting the range of environmental conditions or resources a species can exploit, influences its distribution, persistence, vulnerability to environmental change, and interspecific interactions. The elevational niche‐breadth hypothesis predicts broader ecological niches at higher elevations due to increased environmental stress and ...

Wild meat consumption in changing rural landscapes of Indonesian Borneo

open access: yesPeople and Nature, EarlyView.
Abstract Wild meat can play a crucial role in the food system of rural communities residing near tropical forests.

Irrigation using slightly saline water from emerging desalination technologies as a solution to short‐term drought

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
With global weather patterns becoming more extreme and unpredictable, sourcing reliable irrigation water is vital for improving food security and conserving drinking water in drought‐prone areas. Emerging desalination technologies, which are still in the development phase, could potentially provide large quantities of slightly saline water for ...

Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...

Potential distribution and susceptibility of Coffea arabica L. to climate change impacts

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Ecological niche models (ENMs) are vital for understanding the impact of historical factors on ecosystems and predicting future climate change scenarios. These models help assess how environmental shifts affect agricultural species like coffee, which supports millions of people globally.
