Long‐term experimental drought alters floral scent and pollinator visits in a Mediterranean plant community despite overall limited impacts on plant phenotype and reproduction

Journal of Ecology, Volume 110, Issue 11, Page 2628-2648, November 2022., 2022
In the Mediterranean Basin, climate change is causing an intensification of drought intensity and frequency. Our community‐level in situ measures showed that drought altered floral scent with changes in plant–pollinator interactions and limited impacts on plant reproduction. We discuss why the context of our study—an exceptionally wet year—may have led

Few figs for frugivores: Riparian fig trees in Zimbabwe may not be a dry season keystone resource

African Journal of Ecology, Volume 58, Issue 4, Page 778-785, December 2020., 2020
Abstract Most plants flower and fruit at times of year when probabilities of pollination and seedling establishment are high. Fig trees (Ficus spp.) are often considered as keystone resources for vertebrate frugivores, in part because of year‐round fig production.

Local‐scale tree and shrub diversity improves pollination services to shea trees in tropical West African parklands

Journal of Applied Ecology, Volume 57, Issue 8, Page 1504-1513, August 2020., 2020
Sites with greater diversity of tree and shrub species had more bee visits and less extreme pollination limitation than less diverse sites, indicating that small‐scale diversity is associated with more efficient pollination services. Consequently, shea yields are likely to benefit from retention of a range of different tree and shrub species in ...

Relations pluie pollinique-végétation en Kroumirie (Tunisie septentrionale)

Ecologia mediterranea, 1982
Les relations pluie pollinique-végétation sont précsiées en Kroumirie montagneuse à partir due trois transects de surface réalisés dans des chênaies pures ou mixtes de Quercus suber et Quercus canariensis à sous-bois d’Erica arborea. Il est montré que Q.canariensis est un bien meilleur producteur pollinique que Q.suber et que son pollen pénètre dans ...

Pollen morphology, deep learning, phylogenetics, and the evolution of environmental adaptations in Podocarpus

New Phytologist, Volume 247, Issue 3, Page 1460-1473, August 2025.
Summary Podocarpus pollen morphology is shaped by both phylogenetic history and the environment. We analyzed the relationship between pollen traits quantified using deep learning and environmental factors within a comparative phylogenetic framework.

Servicesheds connect people to the landscapes upon which they depend

People and Nature, Volume 7, Issue 1, Page 112-126, January 2025.
Abstract Ecosystem services (ES) are benefits people receive from nature. To sustain these benefits, we need to spatially connect communities benefitting from specific ES with landscape features that generate the ES. A variety of process‐based models support ES assessments by estimating the biophysical supply of ES that comes from landscapes.

Pollinator functional group abundance and floral heterogeneity in an agroecological context affect mating patterns in a self‐incompatible wild plant

American Journal of Botany, Volume 111, Issue 12, December 2024.
Using a farm‐scale experiment, we investigated how the mating outcomes (expected heterozygosity and paternity correlation) of Cyanus segetum in agroecological infrastructures (herbaceous field margins) are affected by the interplay between pollinator functional group abundance and, respectively, the relative maternal plant attractiveness and the local ...

Modern pollen rain reveals differences across forests, open and mosaic landscapes in Madagascar

PLANTS, PEOPLE, PLANET, Volume 6, Issue 3, Page 729-742, May 2024.
Palaeoecological investigations are crucial in understanding millennial to centennial land use and land cover change. By analysing the modern pollen rain from four main vegetation types across Madagascar, this research provides baselines for improving the interpretation of pollen records in palaeoecological studies.
