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

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 ...

Características morfogênicas e estruturais do capim-xaraés submetido a alturas de corte [PDF]

, 2010
The objective of this work was to evaluate the morphogenetic and structural characteristics of xaraes palisadegrass submitted to three cutting heights (15, 20 and 25 cm) when the sward reached 95% of light interception during regrowth. The experiment was
