Both diurnal and nocturnal pollinators are important in the desert plant Nerine laticoma. Abstract The evolutionary limits to generalization in plant pollination systems are often determined by trade‐offs in which adaptations to one set of flower visitors reduces the effectiveness of another set of visitors.

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

As flower visitors, ants rarely benefit a plant, commonly disrupting pollination by deterring other flower visitors, or stealing nectar. This thesis examines three aspects of ant-flower interactions, focusing on the occurrence of floral traits that ...

Mechanical defenses of plant extrafloral nectaries against herbivory
Extrafloral nectaries play an important role in plant defense against herbivores by providing nectar rewards that attract ants and other carnivorous insects.

Abstract The present opinion deals with the re‐evaluation of sucralose (E 955) as food additive and with the safety of a proposed extension of use in food category (FC) 7.2 ‘Fine bakery wares’. Based on the available data, no safety concerns arose for genotoxicity of sucralose (E 955) and its impurities and degradation products.

Relationship between floral tube length and nectar robbing in Duranta erecta L. (Verbenaceae) [PDF]
Although nectar robbing is a common phenomenon in plant species with tubular flowers or flowers with nectar spurs, the potential effect of this illegitimate interaction on plant reproductive success has not received the deserved attention.

Bumblebees are the most efficient pollinators of raspberry and strawberry in urban environments
We evaluated single‐visit pollination efficiency, on strawberry and raspberry plants, in urban and suburban sites. Bumblebees were overall the most efficient pollinator. For strawberry, bumblebees had equivalent efficiency to honeybees, while for raspberry, bumblebees were more efficient than honeybees.
