Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint

open access: yesThe Anatomical Record, EarlyView.
Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),

Effects of Queen Cell Size and Caging Days of Mother Queen on Rearing Young Honey Bee Queens Apis mellifera L.

open access: yesJournal of Apicultural Science, 2018
This study aims to investigate the effect of queen cell size (9.4 mm, 9.6 mm, 9.8 mm and 10.0 mm) and mother queen caged time (0 day, 2 days and 4 days) on rearing young queens without grafting larvae.

The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Effects of Artificial Sugar Supplementation on the Composition and Nutritional Potency of Honey from Apis cerana

open access: yesInsects
In the global apiculture industry, reward feeding and supplementary feeding are essential for maintaining bee colonies. Beekeepers provide artificial supplements to their colonies, typically in the form of either a honey–water solution or sugar syrup ...

Killing and replacing queen-laid eggs: low cost of worker policing in the honey bee [PDF]

open access: yes, 2014
Worker honeybees, Apis mellifera, police each other’s reproduction by killing worker-laid eggs. Previous experiments demonstrated that worker policing is effective, killing most (∼98%) worker-laid eggs. However, many queen-laid eggs were also killed (∼50%
