Threatened New Zealand Pigeon A Forest Savior
Large-seeded trees rely on native birds for their survival, New Zealand biologists have confirmed. The researchers say this is the first quantitive study of its kind and highlights the impact losing just one species can have on an ecosystem.

Tracking Palm Oil’s Carbon Footprint
For the first time, researchers using satellite techniques have measured and mapped the full extent of South-east Asia's oil palm cultivation – and linked it directly to carbon dioxide emissions

Increased Deer Populations Are Good For Plant Diversity
Over several decades, the growth in deer, roe deer and wild boar populations has spread to all of France. … researchers have shown that in spite of the damage caused, notably to bushes and young trees in forests and to crops, these animals also help in increasing plant diversity.

Invasive Plants A Boon To Bird Diversity
We wondered: Are we sometimes doing more harm than good when we eradicate plants that, despite being introduced recently, have formed positive relationships with native animals?

Grizzlies Starve When Climate Change Kills Pines
We have seen the demise of one of the key food sources for the population in the form of the whitebark pine, the seed cones. While it is one of sort of four pillars of the grizzly bear nutrition source in the Yellowstone ecosystem, in many ways it was extremely important and perhaps more important than many others.

Climate Change And Trees That Disperse Seeds By Wind
According to the research, trees which disperse their seeds by wind, such as pines and maples, will be unable to spread at a pace that can cope with expected climate changes

How Vulnerable Are Mutualists?
Because every species is involved directly or indirectly in mutualistic partnerships and mutualists act as key players in global carbon and nutrient cycles, pollination and seed dispersal, the breakdown of those relationships could accelerate and worsen effects of global change on biodiversity loss and ecosystem disruption.

Shade Grown Coffee Supports Forest Diversity
By pollinating native trees on shade-coffee farms and adjacent patches of forest, the bees help preserve the genetic diversity of remnant native-tree populations.

Amazonia Feeds On The Sahara
One of the most remarkable discoveries of the last decade: the role of deserts as deliverers of nutrients to the rainier parts of the planet.
