The history of wildfires over the past 2,000 years in a northern Colorado mountain range indicates that large fires will continue to increase as a result of a warming climate, according to a new study led by a University of Wyoming doctoral student.

“What our research shows is that even modest regional warming trends, like we are currently experiencing, can cause exceptionally large areas in the Rockies to be burned by wildfires,” says John Calder, a Ph.D. candidate in UW’s Program in Ecology and the Department of Geology and Geophysics.

Scientists have projected that the onset of spring plant growth will shift by a median of three weeks earlier over the next century, as a result of rising global temperatures.

The results, published today (Wednesday 14th October), in the journal Environmental Research Letters, have long term implications for the growing season of plants and the relationship between plants and the animals that depend upon them.

New research by biologists at the University of York shows that plant and insect diversity is more loosely linked than scientists previously believed. Insects and flowering plants are two of the most diverse groups of organism on the planet. For a long time the richness of these two lineages has been regarded as linked, with plant-feeding insect groups considered unusually species rich compared with their nearest relatives. In a new analysis, based on the most complete tree of insect relationships to date, researchers at the University have shown that there is not a simple relationship between insect diet and diversity.

A new study has found that powerful winds are removing massive amounts of snow from parts of Antarctica, potentially boosting estimates of how much the continent might contribute to sea level. Up to now, scientists had thought that most snow scoured from parts of the continent was simply redeposited elsewhere on the surface. However, the new study shows that in certain parts, called scour zones, some 90 percent—an estimated 80 billion tons per year—is instead being vaporized, and removed altogether. 

Thirty-one percent of cactus species are threatened with extinction, according to the first comprehensive, global assessment of the species group by IUCN and partners, published today in the journal Nature Plants. 

This places cacti among the most threatened taxonomic groups assessed on The IUCN Red List of Threatened Species™ - more threatened than mammals and birds.

Ecotourism, in which travelers visit natural environments with an eye toward funding conservation efforts or boosting local economies, has become increasingly popular in recent years. In many cases it involves close observation of or interaction with wildlife, such as when tourists swim with marine animals. Now, life scientists have analyzed more than 100 research studies on how ecotourism affects wild animals and concluded that such trips can be harmful to the animals, whose behaviors may be altered in ways that put them at risk.

By meticulously examining sediments in China's Yellow River, a Swedish-Chinese research group are showing that the history of tectonic and climate evolution on Earth may need to be rewritten. Their findings are published today in the highly reputed journal Nature Communications.

When you think of Chernobyl you probably think along the lines of “nuclear disaster” and a “no-go” area, but new research shows that with humans now absent from the region, several mammal species including wild boar and wolves, are increasing in number in this most unlikely nature reserve.

New research shows that butterflies in Greenland have become smaller in response to increasing temperatures due to climate change. 

It has often been demonstrated that the ongoing rapid climate change in the Arctic region is causing substantial change to Arctic ecosystems. Now Danish researchers demonstrate that a warmer Greenland could be bad for its butterflies, becoming smaller under warmer summers. 

A pre-historical sudden collapse of one of the tallest and most active oceanic volcanoes on Earth — Fogo, in the Cape Verde Islands – triggered a mega-tsunami with waves impacting 220 metres (721 feet) above present sea level resulting in catastrophic consequences, according to a new University of Bristol study published in Science Advances.
