  Frequency-dependent selection by tree squirrels: adaptive escape of nondormant white oaks

  In principal, frequency-dependent selection is one of the most powerful selective forces linking demographic and evolutionary changes, but little is known how such frequency-dependent selection influences predator-prey dynamics in nature. In this study, we used the oak-squirrel system to test the hypothesis that tree squirrels as seed predators/dispersers utilize white oak acorns based on the relative frequency of germination phenotype (dormancy vs. nondormancy), subsequently influencing variation in dispersal patterns of white oaks.

  Unexpected relationships of substructured populations in Chinese Locusta migratoria

  The migratory locust Locusta migratoria is an infamous pest insect with exceptional migratory ability – with dispersal documented over a thousand kilometers. Its distributional area is greater than that of any other locust or grasshopper, occurring in practically all the temperate and tropical regions of the eastern hemisphere. Consequently, minimal population substructuring is expected. However, in marked contrast to its high dispersal ability, three geographical subspecies have been distinguished in China, with more than nine being biologically and morphologically identified in the world. Such subspecies status has been under considerable debate.

  Difference in the inhibition of phospholipases is related to species susceptibility to organophosphate-induced delayed neurotoxicity

  Organophosphate (OP)-induced delayed neurotoxicity (OPIDN) is an axonopathy which is characterized by distal degeneration of some long and large-diameter axons in the peripheral nerves. In sensitive species, OPIDN is initiated when neuropathy target esterase (NTE) is inhibited and aged. A species specific susceptibility to OPIDN has been demonstrated.Adult hens have been widely used as the animal model for experimental studies of OPIDN due to their sensitivity and the development of clinical signs similar to those seen in humans. In contrast, mice, a widely used model animal, is insensitive to sign expression of OPIDN.
