PNAS: Temperature-driven range expansion of an irruptive insect heightened by weakly coevolved plant defenses

PNAS: Temperature-driven range expansion of an irruptive insect heightened by weakly coevolved plant defenses | Plant-insect | Scoop.it

This is a very interesting and clear study about how warming climate is impacting plant-herbivore intereactions. The paper is accessible to students and has a big, far-reaching implication. (It might be especially effective if you live in a region that's suffered the effects of bark beetles, which are serious tree-killers throught the US and Canada - yuck!).

 

"Warming climate has increased access of native bark beetles to high-elevation pines that historically received only intermittent exposure to these tree-killing herbivores. Here we show that a dominant, relatively naïve, high-elevation species, whitebark pine, has inferior defenses against mountain pine beetle compared with its historical lower-elevation host, lodgepole pine."

 

And,

"Consequences extend from reduced food supplies for endangered grizzly bears to altered landscape and hydrological processes."

Nature Communications: An insect-induced novel plant phenotype for sustaining social life in a closed system (2012)

Nature Communications: An insect-induced novel plant phenotype for sustaining social life in a closed system (2012) | Plant-insect | Scoop.it

Foraging, defense and waste disposal are essential for sustaining social insect colonies. Hence, their nest generally has an open structure, wherein specialized castes called workers and soldiers perform these tasks. However, some social aphids form completely closed galls, wherein hundreds to thousands of insects grow and reproduce for several months in isolation. Why these social aphids are not drowned by accumulated honeydew has been an enigma. Here we report a sophisticated biological solution to the waste problem in the closed system: the gall inner surface is specialized for absorbing water, whereby honeydew is promptly removed via the plant vascular system. The water-absorbing closed galls have evolved at least twice independently among social aphids. The plant-mediated waste removal, which entails insect’s manipulation of plant morphogenesis and physiology, comprises a previously unknown mechanism of nest cleaning, which can be regarded as ‘extended phenotype’ and ‘indirect social behavior’ of the social aphids.
