Biological ResearchBackground Recent evidence highlights the key role of wild insects as pollinators in agroecosystems, enhancing fruit set in crops such as sweet cherry (Prunus avium). In Chile, the contribution of wild insects to crop yield remains poorly understood, and

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 ...

Insect Conservation and Diversity, Volume 19, Issue 3, Page 647-659, May 2026.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, Volume 19, Issue 3, Page 469-483, May 2026.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 ...

Year‐round pollinator visitation of ornamental plants in Mediterranean urban parks
Insect Conservation and Diversity, Volume 19, Issue 3, Page 702-715, May 2026.Pollinators visiting ornamental plants in urban parks remained diverse throughout the year. They were represented by wild bees (42%), honeybees (37%), flies (18%), butterflies (2%) and beetles (1%). Both native and non‐native plants attracted pollinators.

Genetic Basis of UV Bullseye Size Variations in Turnip Rape (Brassica rapa subsp. oleifera)
Plant Biotechnology Journal, Volume 24, Issue 5, Page 3189-3200, May 2026.ABSTRACT Floral ultraviolet (UV) patterns are visible to bee pollinators and can affect crop yields by impacting pollinator visitation. However, the mechanisms underlying the intraspecific variations of UV bullseye size remain largely unknown. We analyse the ecological consequences and genetic basis of floral UV bullseye size variation in an important ...

Advanced Engineering Materials, Volume 28, Issue 7, 8 April 2026.Herein, environmental scanning electron microscopy (ESEM) is discussed as a powerful extension of conventional SEM for life sciences. By combining high‐resolution imaging with variable pressure and humidity, ESEM allows the analysis of untreated biological materials, supports in situ monitoring of hydration‐driven changes, and advances the functional ...

Survival rate of honeybee (Apis mellifera) workers after exposure to sublethal concentrations of imidacloprid [PDF]
Imidacloprid is a commonly used systemic insecticide which can induce several sublethal effects. Previous research has not shown any increased mortality in bees that were fed with sublethal doses. However, there is very little research conducted with the
