Predation risk can modify the foraging behaviour of frugivorous carnivores: Implications of rewilding apex predators for plant-animal mutualisms. [PDF]

J Anim Ecol, 2022
Red fox (Vulpes vulpes) foraging placidly on Iberian pear fruits (Pyrus bourgaeana) in one fruit depot created for the field experiment of this study outside Iberian lynx (Lynx pardinus) ranges. Abstract Apex predators play key roles in food webs and their recovery can trigger trophic cascades in some ecosystems.

Pepino (Cucumis sativus L.) cultivado en ambiente protegido: correlaciones entre variables

Tecnología en Marcha, 2021
Se establecieron correlaciones de Pearson para 13 genotipos de pepino producidos bajo invernadero, entre siete variables:  longitud (cm), diámetro (mm) y peso del fruto (g), número de frutos por planta, rendimiento total y comercial (kg/m2), y porcentaje

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
