Europe’s refuge crisis could be worsened by future warming

From National Geographic

In recent years, a refugee crisis has gripped the European Union, as unrest in Syria and elsewhere has sent hundreds of thousands of migrants to Europe’s shores, seeking safe harbor.

Now, a new study says that if all else were to remain equal—a necessary but major if—the stresses of climate change could drive more migrants into the European Union in future years.

As warming worsens, these ...

Leandro Castello’s research explores links between deforestation and fisheries yields in the Amazon

From VT News:

The conversion of tropical forests to crop and pastureland has long been a concern for scientists, as forest loss can lead to decreased rainfall, increased droughts, and degraded freshwater ecosystems. A new study points to another unexpected consequence: changes in fish production.

The study, led by Leandro Castello, assistant professor of fisheries in Virginia Tech’s College of Natural Resources and Environment, explores how deforestation along the Amazon River floodplain affects fisheries yields. The study was published online Dec. ...

Jacob Barney: Invasive plants have a surprising ability to pioneer new climates

From VT News

Virginia Tech scientists have discovered that invasive plant species are essentially able to change in order to thrive on new continents and in different types of climates, challenging the assumption that species occupy the same environment in native and invasive ranges.

It’s no secret that globalization, aided by climate change, is helping invasive species gain a foothold across the planet, but it was something of a surprise to Virginia Tech researchers just how mutable these invaders are.

The study, ...

Dude…Where’d this weed come from?

Globalization and other human activities such as domestication can influence population structure of the earth’s flora and fauna, having broad implications for biodiversity.  For example, Cannabis sativa (a.k.a. hemp/marijuana) has been used by humans for diverse purposes including medicine, spirituality, entertainment, and as a source of fiber for thousands of years.  Because of its broad utility, this plant has been subject to extensive cultivation, artificial selection, and global trade.  As a result, the origins and historical patterns of genetic diversity of marijuana ...

Warning to humanity signed by 16,000 scientists

From CNN

More than 16,000 scientists from 184 countries have published a second warning to humanity advising that we need to change our wicked ways to help the planet.

In 1992, 1,700 independent scientists signed the “World Scientists’ Warning to Humanity.” The letter warned that “human beings and the natural world are on a collision course” and if environmental damage was not stopped, our future was at risk.

That letter made headlines 25 years ago, but the world still faces daunting ...

Carbon emissions are rising again

From National Geographic

For a while it looked as if the world might be turning the corner.

But after a three-year stall in their growth, human-caused carbon-dioxide emissions have not, in fact, peaked, an international team of scientists announced this morning.

In 2017, global emissions of CO2 from fossil fuels and industry will once again rise by 2 percent, the scientists project, to a record 37 billion metric tons. ...

Martha Munoz settles decades-old evolutionary biology question

From VT News:

Evolution can be both stimulated and halted by an animal’s behavior, it just depends which trait you’re talking about, according to a groundbreaking study led by a Virginia Tech researcher.

The study, published Oct. 25 in the journal American Naturalist, shows behavior can be both a brake and a motor for evolution in a manner where slowing evolution in one trait actually requires accelerating evolution in another, according to Martha Read More →
