Indigenous crop diversity maintained despite the introduction of major global crops in an African centre of agrobiodiversity

PLANTS, PEOPLE, PLANET, Volume 5, Issue 6, Page 985-996, November 2023., 2023
The global success and expansion of a small pool of major crops, including rice, wheat and maize, risks homogenising global agriculture. Focusing on the agriculturally diverse Ethiopian Highlands, this study tested whether farm diversity tends to be lower among farmers who grow more introduced crops.

Can heterosis and inbreeding depression explain the maintenance of outcrossing in a cleistogamous perennial?

American Journal of Botany, Volume 110, Issue 10, October 2023., 2023
Abstract Premise What maintains mixed mating is an evolutionary enigma. Cleistogamy—the production of both potentially outcrossing chasmogamous and obligately selfing cleistogamous flowers on the same individual plant—is an excellent system to study the costs of selfing.

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 ...

Vertically stratified frugivore community composition and interaction frequency in a liana fruiting across forest strata

Biotropica, Volume 55, Issue 3, Page 650-664, May 2023., 2023
Our findings suggest a continuous shift in the frugivore community composition along the vertical gradient of a plant species fruiting across forest strata, from a few generalized frugivores in the understorey to a diverse set of specialized frugivores in the canopy.

Mauritia flexuosa fruit production increases with increasing palm height in the Peruvian Amazon

PLANTS, PEOPLE, PLANET, Volume 4, Issue 6, Page 599-604, November 2022., 2022
Fruit number, size, and allometric relationships were evaluated in the Peruvian Amazon for Mauritia flexuosa, a socioeconomically important palm with conservation concerns due to destructive harvest. Significant relationships were found between total fruit number and both palm height and fruit volume. Taller palms experience more crown illumination and

Pollination by bats enhances both quality and yield of a major cash crop in Mexico

Journal of Applied Ecology, Volume 57, Issue 3, Page 450-459, March 2020., 2020
Our study shows that bats provide a vital ecosystem service by pollinating a crop of major socio‐economic importance, and that consideration of both crop quality and yield are essential to fully understanding the benefits of bat pollination. A reduction of this service would result in a decrease in both the size and quality of the harvest, causing ...
