ABSTRACT The Tianshan Mountains, which host two native subspecies of western honeybees, represent the easternmost natural distribution limit of Apis mellifera. The managed Xinjiang black honeybee (XJ), introduced a century ago and designated as a Chinese National Animal Genetic Resource, has expanded rapidly under anthropogenic management.

Comparison among Inbreeding Systems in Maize
The use of less severe inbreeding systems than self-fertilization has been suggested as a means of developing more vigorous maize lines (Zea mays L.). To compare different inbreeding systems, nine traits were evaluated in inbred lines developed by full ...

The effects of florivory and inbreeding on reproduction in hermaphrodites of the wild strawberry, Fragaria virginiana [PDF]
Recently, the biotic context for sexual and mating system evolution in plants has received special attention, yet the significance of interactions with antagonists has only begun to be revealed. We investigated the effect of florivory on reproduction and

Genetic improvement of the herbivorous blunt snout bream (Megalobrama amblycephala) [PDF]
Selection experiments with the herbivorous blunt snout bream or Wuchang bream (Megalobrama amblycephala) were started in 1985. Mass selection for size and length/depth ratio resulted in a significant increase in growth and better shape, while inbreeding ...
