, 2019 Bee pollen production is gradually increasing due to demand for dietary supplements and therapeutic natural products. However, bee products might be unsafe for human consumption, if they originates from plants (families Asteraceae, Boraginaceae and ...

MicroPoem: experimental investigation of birch pollen emissions [PDF]
, 2010 Diseases due to aeroallergens constantly increased over the last decades and affect more and more people. Adequate protective and pre-emptive measures require both reliable assessment of production and release of various pollen species, and the ...

Ecological Entomology, EarlyView.Social bees, especially Meliponini, formed a persistent core that maintained plant–bee interactions across both dry and green seasons in the Caatinga. Persistence was not linked to broader diets; social bees used fewer plant species, despite availability, indicating selective tracking of temporally concentrated floral resources.

Exine, in the form of a natural microcapsule, refers to the outermost layer of the pollen grains and is composed of a complex mixture of sporopollenin, a highly resistant polymer, which makes it durable and able to withstand harsh conditions ...

Ecological Entomology, EarlyView.The outcomes of encounters between honeybees and other flower visitors were observed on two plant species. Pollinators either win, lose or share a resource. Competitive interactions led to greater than expected ‘wins’ for honeybees. The honeybee displaced or gave chase when interacting with another pollinator in at least 20% of winning outcomes ...

Insect Conservation and Diversity, EarlyView.Bees are integral pollinators commonly found in and supported by urban green spaces; however, their eco‐evolutionary response to urbanisation varies interspecifically. While several studies have explored the population and landscape genetics of bees in response to urbanisation, few have examined solitary or specialist species which may be more ...

Insect Conservation and Diversity, EarlyView.Grassland fragmentation effects on cavity‐nesting Hymenoptera are habitat‐specific. Isolated sand steppe fragments are associated with higher brood‐cell abundance. In loess steppes, higher flower frequency increases bee brood‐cell production and parasitoid activity. Abstract The global decline in insects threatens ecosystem functioning, but the drivers

Royal Society Open ScienceAgricultural landscapes often provide an impoverished environment for bees given their limited plant and pollen diversity. Agri-environment schemes (AES) such as flower strips have been developed to improve the quality of the agricultural environment for

Insect Conservation and Diversity, EarlyView.Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...
