Sex, flies and flower trap: Trapping trichomes and their function in pollination
Functional Ecology, Volume 38, Issue 10, Page 2261-2270, October 2024.Read the free Plain Language Summary for this article on the Journal blog. Abstract Trapping trichomes, a common trait found in protogynous trap flowers, are thought to enable interaction with pollinators, promoting both pollen removal and fruit set. However, this hypothesis has yet to be empirically confirmed.

Tropical forest above‐ground productivity is maintained by nutrients cycled in litter
Journal of Ecology, Volume 112, Issue 4, Page 690-700, April 2024.The maintenance of highly productive lowland tropical forests on infertile soils is often attributed to nutrient cycling via litterfall. Almost 40 years after this theory was first proposed, our large‐scale field experiment demonstrates that tree growth and litter production decline in response to long‐term litter removal, providing the first empirical

In two ethnographic case studies in Cambodia and Paraguay, we analyse community‐based Indigenous land titling by focusing ...
