New life for endangered coastal lupine

A rare, coastal flowering plant known as Tidestrom’s lupine — threatened by native deer mice that can munch up to three-quarters of its unripe fruits under cover of an invasive beachgrass — has been given a new life with the large-scale removal of that grass, a long-term study in the journal Restoration Ecology shows.

Hot on the trail of the Asian tiger mosquito

The Asian tiger mosquito (Aedes albopictus) was spotted in Houston in 1985 but can now be found in all of the southern states and as far north as Maine. To reconstruct its spread, scientists turned to the new discipline of landscape genetics. Correlating genetic patterns with landscape patterns, they concluded that the mosquito had hitched a ride along highways. One of only a handful of landscape genetics studies to track an invasive species, this is the first to detect hitchhiking.
