New tracking tags are providing fish-eye views of ways to manage depressed fisheries

New tracking and observing technologies are giving marine conservationists a fish-eye view of conditions, from overfishing to climate change, that are contributing to declining fish populations, according to a new study. Until recently, scientists provided fishery managers only such limited dat...

Using hair to manage HIV/AIDS and predict treatment success

Bacteria manage perfume oil production from grass

Scientists in Italy have found bacteria in the root of a tropical grass whose oils have been used in the cosmetic and perfumery industries. These bacteria seem to promote the production of essential oils, but also they change the molecular structure of the oil, giving it different flavours and pro...

Book on weeds and invasive plants discusses how to manage them using ecological approaches

RIVERSIDE, Calif. As people become more globally mobile, plants can inadvertently get transported with them, resulting in new plants appearing in places not used to hosting them. Such invasions of exotic species can occur rapidly, taking over new territories at the expense of native plants. H...
