Abstract:
... Alterations in water availability and drought events as predicted by climate change scenarios will increasingly impact natural communities with effects already emerging at present. Water deficit leads to increasing physiological stress in plants, likely affecting floral development and causing changes in floral morphology, nectar and pollen production or scent. Understanding how these floral trait ...

Abstract:
... The nectar provision hypothesis predicts that the introduction of nectar-producing plants in agroecosystems benefits parasitoid populations in the field and enhances biological control. Intercropping is a common crop diversification scheme that may bring complementary nectar sources for parasitoids and increase herbivore pest control. For instance, intercropping cereals with faba beans introduces ...

Abstract:
... Adult parasitoids often feed on sugar sources for survival and to fuel energy. Therefore, the provision of sugar sources, such as nectar from flowers, can enhance biological control. We assessed whether Pachycrepoideus vindemmiae and Trichopria drosophilae, two pupal parasitoids of Drosophila spp., can profit from different sugar sources. In a laboratory experiment, we offered honey, cornflower an ...

The degree of these impacts on birds’ diet, habitat use, and ecological niche can be measured by isotopic analysis. We investigated whether the isotopic niche width, food resources, and habitat use of bird trophic guilds diffe ...

Abstract:
... Crinum asiaticum is phenotypically specialised with white, scented, very long-tubed flowers, suggesting that only long-proboscid hawkmoths may be effective pollinators. However, this species has frequently escaped cultivation in many tropical and subtropical regions. We therefore investigated the reproductive biology of C. asiaticum to understand how it is able to naturalise, despite phenotypic sp ...
