Exeter Scientist Discovers UK’s Rarest Bat in East Devon

University of Exeter scientist Dr Fiona Mathews has discovered one of Britain’s rarest mammals living in East Devon.

Members of the public were treated to a surprise close-encounter with the Grey long-eared bat, believed to be one of only 1,000 individuals in the country, at an event organised by East Devon District Council’s Countryside Service at the Axe Estuary Wetlands.

The bat evening was part of a regular Wet and Wild Weekend – a celebration of the wildlife of the Axe Estuary Wetlands attracting nearly 500 people. Dr Mathews and fellow bat-enthusiast Adrian Bayley had set up mist nets so that people could meet some of the animals they were hearing on bat detectors, and were amazed to find the country’s rarest bat.

There are only six known breeding colonies of Grey long-eared bats in the UK. This discovery potentially links an isolated group near Newton Abbot with colonies in Dorset and the Isle of Wight. (more…)

CU-led Mountain Forest Study Shows Vulnerability to Climate Change

A new University of Colorado Boulder-led study that ties forest “greenness” in the western United States to fluctuating year-to-year snowpack indicates mid-elevation mountain ecosystems are most sensitive to rising temperatures and changes in precipitation and snowmelt.

Led by CU-Boulder researcher Ernesto Trujillo and Assistant Professor Noah Molotch, the study team used the data — including satellite images and ground measurements — to identify the threshold where mid-level forests sustained primarily by moisture change to higher-elevation forests sustained primarily by sunlight and temperature. Being able to identify this “tipping point” is important because it is in the mid-level forests — at altitudes from roughly 6,500 to 8,000 feet — where many people live and play in the West and which are associated with increasing wildfires, beetle outbreaks and increased tree mortality, said Molotch.
