Body size and sperm quality in queen‐ And worker‐produced ant males [PDF]
Journal of Evolutionary Biology, 2020 Abstract Workers of many species of social Hymenoptera have functional ovaries and are capable of laying haploid, unfertilized eggs, at least in the absence of a queen. Except for honeybees, it remains largely unknown whether worker‐produced males have the same quality as queen‐produced males and whether workers ...

Queen honey bees exhibit variable resilience to temperature stress
PLoS ONE, 2021 Extreme temperature exposure can reduce stored sperm viability within queen honey bees; however, little is known about how thermal stress may directly impact queen performance or other maternal quality metrics.

Cryptic "royal" subfamilies in honey bee (Apis mellifera) colonies. [PDF]
PLoS ONE, 2018 During emergency queen rearing, worker honey bees (Apis mellifera) select several otherwise worker-destined larvae to instead rear as candidates to replace their dead or failing queen.

The influence of feed quality on the development and productivity of bee queens
Scientific Messenger of LNU of Veterinary Medicine and Biotechnologies, 2021 The research aimed to study the effect of additional protein feeding of foster families with buckwheat stalks. The research was conducted during the summer period in 2020 and 2021. Ten foster families were selected for the experiment. All families are chosen by the method of analogs. Bees were kept in beehives.

Honey bee queen health is unaffected by contact exposure to pesticides commonly found in beeswax
Scientific Reports, 2021 Honey bee queen health is crucial for colony health and productivity, and pesticides have been previously associated with queen loss and premature supersedure.

, 2020 Les objectifs de ce projet étaient de développer des indicateurs précoces et non invasifs de qualité des reines d’abeilles. En parallèle, il a donc procédé (1) au développement d’un outil d’enregistrement de l’activité des reines dans la ruche ainsi qu’au (2) test de la pertinence de différents indicateurs simples (poids, dynamique de colonies) en lien

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017 BackgroundIn cardiac resynchronization therapy (CRT), quadripolar (QUAD) left ventricular (LV) leads are less prone to postoperative complications than non‐QUAD leads. Some studies have suggested better clinical outcomes.
