The effect of maternal care on gene expression and DNA methylation in a subsocial bee

Nature Communications, 2018
Development may be plastic and influenced by parental care. Here, the authors show that experimental reduction of maternal care in the small carpenter bee leads to extensive changes in gene expression and splicing, minor changes in methylation, and ...

Feasibility of Preparing Nesting Box and Luring Large Solitary Carpenter Bee, Xylocopa Valga

Journal of Apicultural Science, 2017
Xylocopa valga, commonly called the carpenter bee and the largest bee with metallicviolet hair cover, is extremely rarely observed in Poland. We hypothesize that a stable and possibly long-term population of X.

Generalization versus specialization in pollination systems: visitors, thieves, and pollinators of Hypoestes aristata (Acanthaceae).

PLoS ONE, 2013
Many recent studies have suggested that the majority of animal-pollinated plants have a higher diversity of pollinators than that expected according to their pollination syndrome.
