Conservative Plants And Climate Change

Most southern hemisphere plants — except for weeds — will not be able to adapt to rapid climate change, a study of more than 11,000 species suggests.

Orchids Can Still Surprise

Oh my God, you've found the missing link. Everyone's been trying to find evolution in action.

Breaking Up Is Just Bad

This does support the concept that landscape fragmentation is restricting the movement of pollinators, and that may be a part of our pollination problem. If we get to the point where almost all patches of forests are fragmented, it's possible that could completely disrupt forest plant ecosystems.

Disappearing Birds Mean Forest Failure

The differences between the distributions of the seeds on Guam and Saipan can be attributed to the differences in their bird populations… In the bird-less forests of Guam, however, fruits ripen, fall off of the tree and settle at tree bases without being eaten or moved by birds.

Where The Trees Are Dying

Trees in western U.S. forests are dying at twice the rate they were a few decades ago, a new study finds. Researchers think the most likely culprit is the regional impacts of global warming.

Bees aren’t All About Honey

Honeybees are important to plants for reasons that go beyond pollination… The insects' buzz also defends plants against the caterpillars that would otherwise munch on them undisturbed.

Trees Can Make Their Own 911 Call

It turned out that a slight difference of acidity between tree and soil creates an imbalance of hydrogen ions, generating voltage. The next question was: What could be done with such limited power?

How Green Is Your Business?

Forests provide pure water and regulate temperatures. Wetlands help mitigate floods. Businesses can hurt these and other ecosystem services (like wind breaks and the pollination of crops) or then can assist and benefit from them. A new report from Business for Social Responsibility (BSR) looks at seven tools business can use to assess their impacts on ecosystem services.

Biodiversity Pays Off

Diversity is valuable socially, economically and now environmentally. Research by Michigan State University scientists has found that growing more corn to produce ethanol creating less diverse landscapes — reduces the ability of beneficial insects to control pests, a loss valued at about $58 million per year in the four states studied.
