The American chestnut may be on the verge of a comeback. More than 125 years after Asian chestnuts arrived in the United States carrying a fungus that caused the near eradication of one of the…

We don’t typically think of forest debris as a food source for freshwater fish and other aquatic organisms, but a study by researchers at the University of Cambridge in England suggests…

For nearly 20 years, Gary Lovett has kept a journal with notes about a variety of natural events taking place in his backyard in southeastern New York, including the date that spring peepers…

Maple syrup producers no longer have to wait for spring weather to know if they are likely to have a good year. A postdoctoral researcher at Tufts University has revealed that sugar maple seed…

Detecting small mammal prey beneath a thick covering of snow is among the more challenging skills that some predators must develop to survive New England winters. Most use exceptional hearing…

The Clean Air Act, passed more than 40 years ago, continues to provide positive outcomes. The latest good news comes from a University of New Hampshire environmental scientist who reports that…

Trees sequester carbon from the atmosphere and play a key role in mitigating the effects of climate change. But a study by researchers at Dartmouth College found that from a climate…

It may be tough to believe after this past year, but it appears that winters are getting shorter and shorter. By studying the growth cycle of vegetation at daily intervals, a team of British…

Since 2010, many white pine trees in northern New England have become infected with one of several fungal diseases that have caused yellow and brown discoloration of one year old needles,…

When Maine zoned two percent of the northern part of the state as deer wintering areas in the 1970s, its goal was to provide habitat that would increase deer density to 10 animals per square…

The materials that birds use to build their nests vary widely between species, from twigs and grasses to mud and even their own saliva. Hawks typically use coarse, dry branches and twigs as…

In northern states, where deep snowpack causes deer to spend much of the winter under the dense canopy of evergreen stands, the animals’ nitrogen-rich waste may be making the soil less…

Satellites are commonly used to monitor large-scale environmental changes, and airplanes are often used to get a clearer picture of the overall health of particular forests. Now, a plant…

Most New Englanders would agree that one way to reduce our environmental impact is to reduce our use of fossil fuels. And most would also agree that switching to wood is a step in the right…

For more than a dozen years Ken Schmidt has been studying how animals eavesdrop on one another. The Texas Tech University professor said that one of his study subjects, the veery, changes its…

The scientific process is a long and complex trail that sometimes leads to dead-ends and conflicting results before clear conclusions can be drawn. Throw in a dose of climate change to muddy…

When the hemlock wooly adelgid, an invasive pest that sucks the life out of eastern hemlock trees, made its appearance in New England forests in the 1970s and 80s, many forestry experts…

Trees capture sunlight to produce chemical energy, and they may soon be teaming up with the sun to produce electricity, as well. A team of researchers at Georgia Institute of Technology and…

For those concerned about climate change, renewable energy development is a nobrainer. And the breezy mountaintops of New England, far from human population centers, appear to be ideal…

Climate change is affecting a wide range of wildlife, from plants and bees to birds and trees. A new study led by biologists at Boston University adds butterflies to the list, finding that…
