3D pollination biology using micro‐computed tomography and geometric morphometrics in Theobroma cacao

Applications in Plant Sciences, Volume 11, Issue 5, September-October 2023., 2023
Abstract Premise Imaging technologies that capture three‐dimensional (3D) variation in floral morphology at micro‐ and nano‐resolutions are increasingly accessible. In herkogamous flowers, such as those of Theobroma cacao, structural barriers between anthers and stigmas represent bottlenecks that restrict pollinator size and access to reproductive ...

Promoting landscapes with a low zoonotic disease risk through forest restoration: The need for comprehensive guidelines

Journal of Applied Ecology, Volume 60, Issue 8, Page 1510-1521, August 2023., 2023
Our results contribute to a more comprehensive forest restoration planning, comprising multiple ecosystem services and resulting in healthier landscapes for both people and nature. Our framework could be integrated into the post‐2020 global biodiversity framework targets.

Forest structure predicts species richness and functional diversity in Amazonian mixed‐species bird flocks

Biotropica, Volume 55, Issue 2, Page 467-479, March 2023., 2023
We show that vegetation structure can predict species richness and functional diversity in Amazonian mixed‐species flocks in primary and secondary forests. In addition, we show that secondary forest flocks retain a large percentage of the functional diversity exhibited by their primary forest counterparts. Abstract Secondary forest has the potential to

Providing long‐term care: Options for a better workforce

International Social Security Review, Volume 75, Issue 3-4, Page 121-144, July-December 2022., 2022
Abstract Older people and their care workers have been disproportionately affected by the COVID‐19 pandemic. Many OECD Member countries have taken measures to contain the spread of the infection and improve the care workforce. Yet the health crisis is highlighting and exacerbating pre‐existing structural problems in the long‐term care (LTC) sector.

Variation of non‐structural carbohydrates across the fast–slow continuum in Amazon Forest canopy trees

Functional Ecology, Volume 36, Issue 2, Page 341-355, February 2022., 2022
A free Plain Language Summary can be found within the Supporting Information of this article. Abstract Tropical tree species span a range of life‐history strategies within a fast–slow continuum. The position of a species within this continuum is thought to reflect a negative relationship between growth and storage, with fast‐growing species allocating ...

Effects of time since invasion and control actions on a coastal ecosystem invaded by non‐native pine trees

Ecological Solutions and Evidence, Volume 3, Issue 1, January–March 2022., 2022
Pine invasion reduced native species abundance, plant cover, richness and diversity, with an increase over time since invasion. Species diversity and richness were lower in the managed area than in the area that had not been invaded. Restoration activities are therefore required to increase native species diversity.

Warming of aquatic ecosystems disrupts aquatic–terrestrial linkages in the tropics

Journal of Animal Ecology, Volume 90, Issue 7, Page 1623-1634, July 2021., 2021
Using tank‐bromeliads, the authors experimentally investigated for the first time how aquatic–terrestrial linkages are affected by warming in the tropics. In contrast to temperate regions, warming is predicted to cause strong declines in tropical aquatic insect emergence into terrestrial ecosystems, while variably affecting terrestrial detritus ...
