Seas between the islands of Skye and Mull on Scotland’s west coast are highly important for basking sharks, according to a report published by Scottish Natural Heritage (SNH).

Each year large numbers of basking sharks are seen in an area of the Sea of the Hebrides which is currently being assessed as part of the Scottish Marine Protected Areas Project.

The report sets out findings from the first two years of a project which aims to reveal some of the mysteries surrounding the world’s second largest fish. The project is a joint venture between SNH and the University of Exeter, and is the first known to use satellite tagging technology to track the near real-time movements of basking sharks. (more…)

Glaciers existed in Britain as late as Georgian era

New evidence indicates glaciers present 11,000 years later than believed

Research led by a scientist from the University of Exeter has shown that Britain was home to small glaciers within the last few centuries – around 11,000 years later than previously thought.

Dr Stephan Harrison of Geography has established that small glaciers almost certainly existed in the Cairngorm mountain range in Scotland as recently as the 18^th century, contrary to the long held belief that Britain’s last glaciers melted around the 9^th millennium BC. (more…)

Dolphins keep lifelong social memories, longest in a non-human species

Dolphins can recognize their old tank mates’ whistles after being separated for more than 20 years—the longest social memory ever recorded for a non-human species.

The remarkable memory feat is another indication that dolphins have a level of cognitive sophistication comparable to only a few other species, including humans, chimpanzees and elephants. Dolphins’ talent for social recognition may be even more long-lasting than facial recognition among humans, since human faces change over time, but the signature whistle that identifies a dolphin remains stable over many decades.

Spiral galaxies like Milky Way bigger than thought, says CU-Boulder study

Let’s all fist bump: Spiral galaxies like our own Milky Way appear to be much larger and more massive than previously believed, according to a new University of Colorado Boulder study by researchers using the Hubble Space Telescope.

CU-Boulder Professor John Stocke, study leader, said new observations with Hubble’s $70 million Cosmic Origins Spectrograph, or COS, designed by CU-Boulder show that normal spiral galaxies are surrounded by halos of gas that can extend to over 1 million light-years in diameter. The current estimated diameter of the Milky Way, for example, is about 100,000 light-years. One light-year is roughly 6 trillion miles. (more…)

Ecologists Shed New Light on Effects of Light Pollution on Wildlife

Light pollution is often associated with negative effects on wildlife. Now, ecologists have found that by mimicking a perpetual full moon, the gas flares and electrical lighting along Scotland’s Forth estuary are helping shorebirds stock up on more food during the winter to fuel their spring migration.

The research is the first to use night-time light data from US military satellites to study animal behaviour.

Coasts and estuaries are among the most rapidly developing areas on Earth. Night-time satellite images of the planet show that except Antarctica, continents are ringed with halos of brightly-lit human development. But coasts are also key wildlife sites. Every year, millions of waterbirds arrive from the Arctic to overwinter on UK coasts, yet scientists remain largely in the dark about how these birds respond to the bright lights of coastal cities and industry.

The Original Twitter? Tiny Electronic Tags Monitor Birds’ Social Networks

If two birds meet deep in the forest, does anybody hear? Until now, nobody did, unless an intrepid biologist was hiding underneath a bush and watching their behavior, or the birds happened to meet near a research monitoring station. But an electronic tag designed at the University of Washington can for the first time see when birds meet in the wild.

A new study led by a biologist at Scotland’s University of St. Andrews used the UW tags to see whether crows might learn to use tools from one another. The findings, published last week in Current Biology, supported the theory by showing an unexpected amount of social mobility, with the crows often spending time near birds outside their immediate family.

Public Sightings Suggest Increase in Basking Sharks in British Waters

The number of basking sharks recorded in Britain’s seas could be increasing, decades after being protected from commercial hunting in the late 20^th century.

The most comprehensive analysis ever undertaken of basking shark sightings in UK waters, by the University of Exeter, the Marine Conservation Society (MCS), Cornwall Wildlife Trust (CWT) and Wave Action, is published in the journal Marine Ecology Progress Series.

The northeast Atlantic hosted an extensive commercial fishery for basking sharks, mainly in Norway, Ireland and Scotland, where more than 81,000 were killed between 1952 and 2004, hunted largely for their liver oil. Large-scale hunting ended in the UK in the middle of the twentieth century, though it continued at low levels in Norway until 2000. (more…)
