Behavioral thermoregulation in the migratory locust: a therapy to overcome fungal infection.

abstract：:Fruiting phenology and pattern of fruit removal of two shrubby dogwoods were examined in relation to fruit composition. It was predicted that fruit of the species bearing high fat fruit would disappear more rapidly and fall to the ground sooner than fruit of the species bearing low fat fruit. Field observation at two ...
