Вестник Костромского государственного университета им. Н.А. Некрасова, 2011 The year cycle of crystallization point of different departments of a body of honeybee is shown in dynamics. Distinction of crystallization point of tissues of honeybee in Apis mellifera mellifera and Apis mellifera carnica is noted. The given indicator will allow to explain the mechanism of adaptation of bees at physiological level to adverse winter ...

European Journal of Oral Sciences, EarlyView.Abstract This in vitro study evaluated the effect of hydroalcoholic propolis extract (HPE) as a collagen cross‐linking agent for preserving the dentin–adhesive interface. Dentin beams from human third molars were demineralized with 10% phosphoric acid and assigned to five treatments: distilled water (control), 6.5% grape seed extract (GSE), and HPE at ...

Bee community and trait‐based responses to fire in a Mediterranean landscape
Insect Conservation and Diversity, EarlyView.Fire drives a short‐term increase in bee abundance and diversity, despite its strong negative impact on floral resources. Acting as an environmental filter, fire shapes bee communities as increased post‐fire fine‐scale heterogeneity favors bees with specific functional traits such as ground‐nesting and generalist species.

Insect Conservation and Diversity, EarlyView.Orchards supported the highest wild bee diversity and functional diversity, highlighting their role in maintaining bee communities in Mediterranean agroecosystems. Landscape heterogeneity positively influenced functional evenness and dispersion of wild bee communities, underscoring the importance of diverse landscapes for bee conservation. The presence

Estimating wild bee population size with validated distance sampling
Insect Conservation and Diversity, EarlyView.Distance Sampling is a promising method to estimate population size but has never been validated on insects. We validated it on a honey bee population of known size. We applied Distance Sampling to three insular pollinators and found that estimates are consistent across days, match species phenology and reflect the expected influence of weather ...
