Taxonomic revision and identification keys for the giant honey bees
Frontiers in Bee ScienceIntroductionThe taxonomy and phylogeny of the giant honey bees (Apis; subgenus Megapis) remain controversial and unresolved. The species boundaries within the subgenus are unclear, and some species that are recognized on the basis of genetic differences ...

Large‐Scale Flat Silk Cocoons as a Highly Effective Salt‐Resistant Low‐Cost Solar‐Powered Evaporator
Advanced Science, EarlyView.This work is the first large‐scale preparation of solar seawater evaporators using natural flat silk cocoons. The flat silk cocoon's natural fibrous transverse multilayers combined with a Janus structure minimize heat loss and salt crystallization, while providing extremely fast water transport and evaporation rates.

The Cuticular Waterproofing Mechanism of the Worker Honey-Bee [PDF]
Journal of Experimental Biology, 1955 ABSTRACT It is now widely accepted, following the work of Alexander, Kitchener and Briscoe (1944 a–c), Wigglesworth (1944, 1945) and Beament (1945), that the thin layer of lipoid material which is present on or near the outer surface of insect cuticle serves to restrict the evaporation of water from the animal.

Advanced Science, EarlyView.A simplified chemoenzymatic platform is designed to integrate an enzyme cascade with subsequent chemical steps, enabling the divergent production of diverse benzylisoquinoline alkaloids (BIAs). Demonstrating remarkable versatility and enantioselectivity, four distinct classes of BIAs are efficiently generated, in which the natural medicine papaverine ...

The bumble bees (Hymenoptera: Apidae: Bombus) of Arkansas, fifty years later [PDF]
, 2015 Many species of bumble bees (Hymenoptera: Apidae: Bombus Latreille) are declining throughout their ranges in North America, yet detecting population trends can be difficult when historical survey data are lacking. In the present study, contemporary data
