Alberta’s predator compensation program offsets costs of conserving wildlife habitat on private lands in the province.

Some Antarctic fish living in the planet’s coldest waters are able to cope with the stress of rising carbon dioxide levels in the ocean. They can even tolerate slightly warmer waters. But they can’t deal with both stressors at the same time, according to a study from the University of California, Davis.

When some Colombian potato varieties are lightly grazed by a pest, the plants respond by growing larger tubers, at times doubling their yields. Although many types of plants can repair pest damage while maintaining productivity, it’s rare to find species that actually overcompensate and increase productivity.

In 1854, a curious-looking spider was found preserved in 50 million-year-old amber. With an elongated neck-like structure and long mouthparts that protruded from the “head” like an angled beak, the arachnid bore a striking resemblance to a tiny pelican. A few decades later when living pelican spiders were discovered in Madagascar, arachnologists learned that their behavior is as unusual as their appearance, but because these spiders live in remote parts of the world they remained largely unstudied—until recently.

ETH researchers reveal why Arctic sea ice began to melt in the middle of winter two years ago – and that the increased melting of ice in summer is linked to recurring periods of fair weather.

Academics in Sweden, Germany, France, Estonia and Switzerland sought to establish how the nature of Europe’s forests has changed over 11,000 years. More than half of Europe’s forests have disappeared over the past 6,000 years thanks to increasing demand for agricultural land and the use of wood as a source of fuel, new research led by the University of Plymouth suggests.

Phytoplankton blooms are one of the most important factors contributing to the efficiency of the carbon pump in the North Atlantic Ocean. To better understand this phenomenon, the ERC remOcean1 project, led by researchers at the Laboratoire d'Océanographie de Villefranche (CNRS/UPMC), has developed a new class of robots: biogeochemical profiling floats, the first robots able to collect data in the ocean throughout the year. Using these unparalleled data, the researchers have identified the starting point for the explosive spring phytoplankton bloom. Their results are the subject of two articles published in Nature Geoscience and Nature Communications.

Increased fluctuations in the path of the North Atlantic jet stream since the 1960s coincide with more extreme weather events in Europe such as heat waves, droughts, wildfires and flooding, reports a University of Arizona-led team.

The research is the first reconstruction of historical changes in the North Atlantic jet stream prior to the 20th century. By studying tree rings from trees in the British Isles and the northeastern Mediterranean, the team teased out those regions' late-summer weather going back almost 300 years — to 1725.

Water contaminated by the oil currently leaking into the ocean from the Sanchi tanker collision is likely to take at least three months to reach land, and if it does the Korean coast is the most likely location. However, the oil’s fate is highly uncertain, as it may burn, evaporate, or mix into the surface ocean and contaminate the environment for an extended duration.

A new study from the British Antarctic Survey shows how lanternfish, small bioluminescent fish, are likely to respond to the warming of the Southern Ocean.
