  Elevated CO2 reduces the response of grain aphid to alarm pheromone

  The aphid alarm pheromone (E)-β-farnesene (EβF), an altruistic chemical signal, is released by attacked aphids to protect other aphids from natural enemies,resulting in various behavioral reactions, such as increased alertness, non-feeding, and moving away from or dropping off the host plant.

  Leptin plays important role during cold adaptation in Brandt’s voles

  Brandt’s voles Lasiopodomys brandtii exhibit large increases in nonshivering thermogenesis to cope with chronic cold exposure, resulting in compensatory hyperphagia and fat mobilization. These physiological events are accompanied by a remarkable reduction in serum leptin levels. However, the role of hypoleptinemia in cold adaptation in this species is still unknown. In the present study, we tested the hypothesis that hypoleptinemia contributes to increases in food intake and brown adipose tissue (BAT) thermogenesis by modifying hypothalamic neuropeptides in cold-exposed Brandt’s voles.

  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.
