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.

Local and regional‐scale effects of hedgerows on grassland‐ and forest‐associated bird populations within agroecosystems

Ecological Applications, Volume 34, Issue 3, April 2024.
Abstract Linear woody features (LWFs), like hedgerows along field edges, provide wildlife habitat and support biodiversity in agroecosystems. Assessments of LWFs usually focus on community‐level indices, such as species richness. However, effective conservation actions need to balance the contrasting habitat preferences of different wildlife species ...

Supplemental nesting habitat increases bee abundance in apple orchards

Journal of Applied Ecology, Volume 61, Issue 3, Page 442-451, March 2024.
These findings suggest that bee populations in apple orchards can be limited by nesting resources such that addition of constructed nesting habitat could be an effective means of increasing pollinator numbers in orchards, and potentially, supporting bee conservation.

Etude de la pluie pollinique actuelle des forêts du Brésil central : climat, végétation, application à l'étude de l'évolution paléoclimatique des 30.000 dernières années

, 1991
Les caractéristiques climatiques de cinq types de forêts du Brésil central (forêt d'araucaria, forêt mésophile semidécidue, forêt galerie, cerrado et cerradao) sont définies en fonction de la durée de la saison sèche et de la température moyenne hivernale.

Revue des sciences naturelles d'Auvergne, 2009
Une étude des rapports entre végétation et pluie pollinique actuelle a été menée sur le plateau de Millevaches (Limousin, France) de façon à préciser les caractérisations palynologiques, sur le long terme, des dynamiques paysagères et des pratiques territoriales associées.
