  Regulation of neuropathy target esterase by the cAMP/protein kinase A signal

  Neuropathy target esterase (NTE) was identi？ed as the primary target of the organophosphorus compounds (OP) that cause a syndrome calledOP-induced delayed neuropathy (OPIDN), characterized by paralysis of the lower limbs due to degeneration of long axons in the spinal cord and peripheral nerves. It has been suggested that the inhibition and subsequent ageing of NTE initiates OPIDN.

  Mutualistic invasion of the invasive red turpentine beetle and its fungal associate

  Recent studies have investigated relationships between pairs or groups of exotic species to illustrate invasive mechanisms, but most have focused on interactions at a single trophic level. Here, we conducted pathogenicity tests, analyses of host volatiles, and fungal growth tests to elucidate an intricate network of interactions between the host tree, the invasive red turpentine beetle, and its fungal associates.Seedlings inoculated with two strains of Leptographium procerum isolated from Dendroctonus valens in China had significantly longer lesions and higher mortality rates than seedlings inoculated with other fungal isolates.

  Ambient temperature affects maternal investment strategies in lactating Brandt’s voles

  The maximum rate of sustained energy intake (SusEI) may limit reproductive effort, thermoregulatory capability and other aspects of an animal’s energy expenditure. Consequently, factors that limit SusEI are of interest. The ‘heat dissipation limitation hypothesis’ suggests that maximum SusEI during lactation is limited by the capacity to dissipate body heat generated as a byproduct of processing food and producing milk. In the present study, we tested the heat dissipation limitation hypothesis in lactating Brandt’s voles (Lasiopodomys brandtii). Female voles were mated and pregnant at 21(±1) °C. A random sample of animals was transferred into a hot room 30(±1) °C on the day of parturition.
