Pollination syndromes in a Caatinga plant community in northeastern Brazil: seasonal availability of floral resources in different plant growth habits

Brazilian Journal of Biology
To describe plant phenological patterns and correlate functioning for the quantity and quality of resources available for the pollinator, it is crucial to understand the temporal dynamics of biological communities.

Beyond flowers: including non-floral resources in bee conservation schemes

Journal of Insect Conservation, 2020
Land-use change and habitat loss have profoundly disturbed the resource availability for many organisms in farmlands, including bees. To counteract the resulting decline of bees and to maintain their pollination service to crops, bee pollinator-friendly schemes have been developed.

Local influence of floral resource attributes on urban bumble bee foraging activity

Frontiers in Sustainable Cities, 2023
IntroductionUrbanization diminishes the extent of uncompacted, exposed soil and the coverage of wild plant species, yet still supports diverse pollinator communities when their habitat is maintained within the built environment.

Grass flowers: An untapped resource for floral evo‐devo [PDF]

Journal of Systematics and Evolution, 2017
AbstractThe abrupt origin and rapid diversification of the flowering plants presents what Darwin called “an abominable mystery”. Floral diversification was a key factor in the rise of the flowering plants, but the molecular underpinnings of floral diversity remain mysterious. To understand the molecular biology underlying floral morphological evolution,

Influence of group size and floral display on pollinator behaviour in Moricandia arvensis

Journal of Pollination Ecology
Optimal foraging theory predicts that pollinators will visit dense floral patches over sparse ones. Understanding how the local abundance of floral resources influences pollinator behaviour is crucial for assessing the effect of floral traits on plant ...

Floral resource distribution and fitness consequences for two solitary bee species in agricultural landscapes

Basic and Applied Ecology, 2022
Floral resources are crucial for wild pollinators. Identifying the spatio-temporal floral resource use of wild pollinators and effects of resource distribution on their development might help to promote them and their pollination services to crops in ...

Floral resources shape parasite and pathogen dynamics in bees facing urbanization

Molecular Ecology, 2022
AbstractUrbanization is associated with increases in impervious land cover, which alters the distribution of resources available to wildlife and concentrates activity in unbuilt spaces such as parks and gardens. How resource shifts alter the dynamics of parasite and pathogen transmission has not been addressed for many important species in urban ...

Enhancing floral resources for pollinators in productive agricultural grasslands [PDF]

Biological Conservation, 2014
Across N.W. Europe intensive agricultural management has increased productivity to the detriment of floral resources vital for insect pollinators like bees, butterflies and hoverflies. While the creation of wildflower habitats has been widely used to re-establish such resources into arable ecosystems (e.g.

Evaluating floral resource availability in mountain habitats

Ecosphere
Abstract Climate‐driven phenological mismatches have the potential to disrupt plant–pollinator interactions, emphasizing the need to uncover drivers behind spatial and temporal dynamics of floral resource availability. This is especially important in habitats such as mountain meadows, where climate change is not only likely to have ...

Food niche of solitary and social bees (Hymenoptera: Apoidea) in a Neotropical Savanna

Sociobiology, 2020
In this study we investigated the group of floral resources that support bee populations from a bee assemblage in a savanna, and the way in which bee species use these food resources, with an emphasis on the breadth and overlap of trophic niches.
