• Spring will be springing earlier in the US

    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.

  • Re-thinking plant and insect diversity

    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.

  • Winds Carve Away Antarctic Snow

    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.

  • Nearly 1/3 of world's cacti species facing extinction

    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 can put wild animals at risk

    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.

  • Study of China's Yellow River yields unexpected information about the Earth's climate history

    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.

  • Chernobyl considered unlikely nature reserve for some species

    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.

  • Arctic butterflies adapt to warming climate by getting smaller

    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.

  • Evidence confirms volcanic island collapses may trigger mega-tsunamis

    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.

  • New Sensor Tag Technology Could Link Animal Behavior and Conservation Science

    For wild sockeye salmon, the trip upriver from the ocean to their spawning grounds is fraught with peril and hardship. But quantifying exactly how obstacles along the way, fluctuations in water temperature and other factors impact fish survival has long eluded researchers. New advances in biological sensor tags are now allowing scientists to precisely measure animals’ energetics, their interactions with humans, and their responses to rapidly changing environments.

    In 2014, for example, Nicholas Burnett and colleagues used accelerometer tags to measure how salmon needed to swim in order to traverse a dam in the Seton-Anderson watershed of British Columbia, Canada and how likely they were to survive the remainder of their journey. They found that when salmon resort to strenuous anaerobic swimming, they were significantly more likely to die days or even hours later.
