Researchers discover key gene involved in bark beetle pheromone production

...otected. Only for a few hours do they fly from one tree to another to join other bark beetles, mate and start a new life cycle. But other bark beetles know where to locate mates because they are responding to an "aggregation" pheromone. If this pheromone could be disrupted, the beetles wouldn't be able to...

The central patch was connected to one other patch by a 150-meter-long, 25-meter-wide corridor, while three ot...

Expanding forests darken the outlook for butterflies, study shows

...eadows. According to Roland, the altitude of the tree line in the Canadian Rockies is rising--likely due to global warming--and, outside of national parks, forest fires are usually suppressed. These factors are combining to create larger forests and smaller alpine meadows. This is bad news for butterfli...

Invasive honeysuckle opens door for new hybrid insect species

The animal family tree may not be filled just with forks, but may also contain knots: hybrid species with two different ancestors rather than one, according to a team of Penn State researchers. "We are looking for the origin of species," says Dr. Dietmar Schwarz, post-doc...

The key to making this system work for increased productivity is tracking the pedigree of plants and animals to k...

The most important role of flowers is, however, that they give rise to fruits and seeds, including all the cereal grains, and thus are the basis of much of our daily lives.
