New paper from Liz Wason


Liz Wason and coauthors Anurag Agrawal and Mark Hunter published a paper on latitudinal variation in herbivore-induced emission of plant volatile compounds (VOCs). Many plants emit volatile compounds, and in many cases the emissions increase when plants are damaged by herbivores, and this is often beneficial for plants because the VOCs often attract natural enemies of herbivores.  Liz and colleagues studied a common garden of milkweed plants collected from 20 populations originating across 10 degrees of latitude, and found that herbivore-induced emission of VOCs was greater at high versus low latitudes. Their work, in combination with previous studies, suggests that milkweeds do not show a pattern of greater defense against herbivores at low latitudes.
