[CBNPMP-Thèmes] Aménagement du territoireRésumé : Les pollinisateurs représentent un enjeu important pour la biodiversité et l’alimentation humaine. Sans l’aide des pollinisateurs tels que les abeilles, les bourdons, les guêpes …, les cultures se limiteraient principalement aux céréales. Il est donc primordial de les protéger. Les surfaces végétalisées qui bordent les routes ou dépendances vertes comme les accotements, les fossés, les talus présentent un intérêt notable pour les pollinisateurs sauvages. Elles forment un corridor potentiellement important pour préserver la biodiversité dans un contexte de dégradation des habitats naturels. Cet ouvrage qui s’appuie sur des travaux de recherche concernant les pollinisateurs sauvages propose aux gestionnaires routiers des recommandations de gestion raisonnée des dépendances vertes adaptées aux pollinisateurs sauvages. Il est constitué de fiches traitant des enjeux et des caractéristiques des dépendances vertes routières, des besoins des pollinisateurs, de l’entretien et de la conception de ces espaces de biodiversité. Des fiches actions présentent ensuite les différents leviers potentiels pour améliorer l’accueil et le développement de la biodiversité notamment des pollinisateurs sauvages sur les dépendances vertes routières.

[LOTERRE-Biodiversité] PollinisateurRésumé : Habitat restoration to promote wild pollinator populations is becoming increasingly common in agricultural lands. Yet, little is known about how wild bees, globally the most important wild pollinators, use resources in restored habitats. We compared bee use of native and exotic plants in two types of restored native plant hedgerows: mature hedgerows (>10 years from establishment) designed for natural enemy enhancement and new hedgerows (≤2 years from establishment) designed to enhance bee populations. Bees were collected from flowers using timed aerial netting and flowering plant cover was estimated by species using cover classes. At mature hedgerow sites, wild bee abundance, richness, and diversity were greater on native plants than exotic plants. At new sites, where native plants were small and had limited floral display, abundance of bees was greater on native plants than exotic plants; but, controlling for floral cover, there was no difference in bee diversity and richness between the two plant types. At both mature and new hedgerows, wild bees preferred to forage from native plants than exotic plants. Honey bees, which were from managed colonies, also preferred native plants at mature hedgerow sites but exhibited no preference at new sites. Our study shows that wild bees, and managed bees in some cases, prefer to forage on native plants in hedgerows over co-occurring weedy, exotic plants. Semi-quantitative ranking identified which native plants were most preferred. Hedgerow restoration with native plants may help enhance wild bee abundance and diversity, and maintain honey bee health, in agricultural areas.

Saxifraga stellaris L. Résumé : The pollination and reproductive ecology of Saxifraga stellaris was investigated in alpine southwest Norway. A breeding system analysis, with performance of controlled crosses, revealed that S. stellaris is self-compatible and that reproductive success after cross- and self-pollination is equal. Relative autodeposition efficiency (i.e. mean seed:ovule ratio in caged, nonmanipulated plants relative to mean seed:ovule ratio of control plants) was, however, low (0.29), suggesting that S. stellaris depends on insect visitation for maximum seed set. Seed set is not restricted by pollen availability, as indicated by a supplemental hand-pollination experiment. Plant size had a strong positive impact on ovule number, which in turn was positively correlated with seed number. Plant size also had a positive influence on seed weight. Seed weight was lowest for late-flowering plants, suggesting that shorter time for seed maturation and lower temperatures late in the season restrict seed weight. No correlations between flowering date and seed number were found, perhaps because the pollinators are relatively insensitive to temperature conditions and thus their activity does not change through the flowering season of S. stellaris.

[CBNPMP-Thèmes] MessicoleRésumé : 1. Non-crop (segetal) plants in arable systems are commonly perceived simply as ‘weeds’, that is, harmful at worst and undesirable at best. The increase in management intensity in European arable systems has vastly reduced the populations of all but the most disturbance-tolerant plant species, negatively impacting the whole agricultural food web. In recent years, efforts have been made to promote agricultural biodiversity through measures such as flower strips and unsprayed field margins. However, studies of their impacts on the arable flora have rarely considered their spatial variation within the crop field.
2. We investigated the spatial distribution of vascular plant species richness and their contribution to the food web via biomass and flower units in conventional and agri-environment cereal fields in six regions of Germany. We studied two types of in-crop measures (extensive cereals without pesticides or fertiliser, and with or without intercropping with flowering species) and one adjacent measure (neighbouring flower strip), recording at 1-m intervals from the field edge to the interior. These results were then extrapolated to illustrate the effects of these measures on resource provision at the field scale.
3. Species richness and plant biomass dropped off sharply after the first metre in the conventional treatments, regardless of the adjacent habitat. The ‘extensive’ treatments maintained a much higher level of diversity and resource provision in the field interior. At the field level, this can mean more than a 60-fold difference in the provision of flowering resources between conventional management (1900 flower units/ha) and agri-environment measures (AEMs) (127,000 units/ha for extensive cereals).
4. Synthesis and applications. The strong edge effects we found in conventional cultivation support the premise that reducing field sizes could play a role in promoting in-crop biodiversity. However, incorporating extensive field margins as an AEM would be more efficient at maximising the diversity of generalists whilst maintaining high yields.
