Vietnamese pygmy dormouse uses ultrasound for navigation

January 10, 2017: Researchers ... discovered the Vietnamese pygmy dormouse makes ultrasonic noises similar to those used by some bat species, and videos showed they made the sounds at a much greater pulse rate when moving than while resting. These sound waves bounce off objects, allowing the rodent to sense its surroundings—an ability known as echolocation, or biological sonar. The find makes the dormouse the only tree-climbing mammal known to use ultrasonic echolocation, the team reports in Integrative Zoology.

The use of Netlon® mesh to reduce the risk of exposed Breathable Roofing Membranes (BRM) to roosting bats.

July 1, 2015: The interaction between bats and Breathable Roofing Membranes (BRM) is becoming increasingly brought to the forefront of bat conservation; particularly as sustainable solutions to building maintenance and functionality are being sought and applied. A number of recent publications have highlighted cases of entanglement of bats in BRMs. Until further research is undertaken an interim solution to deal with the use of BRMs retrospectively is required. In this article bat consultants Chris J. Damant and Emily L. Dickins desribe three cases where Netlon® mesh has been used to reduce the risk of exposed BRM to roosting bats.

Success in Saving Bats From White-Nose Syndrome

May 20, 2015: Scientists and conservationists gathered outside the historic Mark Twain Cave Complex in Hannibal, Missouri, to release back into the wild some of the first bats successfully treated for deadly White-Nose Syndrome. The 150 bats released were part of the first field trials of a novel way to protect bats from this syndrome.

Bat research by Israeli scientist alters concepts on mammal hibernation

11 May 2015: Hibernation was believed to occur only in low temperatures, as mammals sleep through three to nine months of cold and hazardous winter with a very low heart rate and body temperature. But this is not the case in two species of the mouse-tailed bat (the Rhinopoma microphyllum and the R. Cystops). ...

US DoE funds development of ultrasonic bat deterrents

20 April 2015: Bat Conservation International’s (BCI) efforts to address the problem of protecting wildlife while enhancing the responsible operation of this source of clean energy was boosted last week with funding from the US Department of Energy (DOE) for our acoustic bat deterrent research program. The DOE announced more than $1.75 million for five projects that will develop and demonstrate technologies to reduce the impacts of wind energy facilities on bats.

Is the noctule bat really uncommon?

1 April 2015: This article explores some of the challenges of assessing the significance of impacts on noctule bat Nyctalus noctula from onshore wind farms in the UK.

Lincoln Castle revamp work adapted after bat discovery

17 March 2015: Part of a medieval castle has had to be specially adapted after bats were found living on the grounds.

Switch off the lights for bats

16 March 2015: New research has discredited the popular belief that street lighting is attractive to common bats. The study, carried out by scientists from the University of Exeter and Bat Conservation Ireland, found that bat activity was generally lower in street-lit areas than in dark locations with similar habitat.

Anthropogenic noise alters bat activity levels and echolocation calls

Jan 2015: Negative impacts from anthropogenic noise are well documented for many wildlife taxa. Investigations of the effects of noise on bats however, have not been conducted outside of the laboratory. Bats that hunt arthropods rely on auditory information to forage. Part of this acoustic information can fall within the spectrum of anthropogenic noise, which can potentially interfere with signal reception and processing.

Disposal of Middleton In Teesdale Field Studies Centre

15 December 2014: The County Council of Durham (the Council) hereby gives notice that on the 3rd November 2014 it received a notification from the owner of an intention to dispose of Middleton-in-Teesdale Field Studies Centre listed by the Council as an Asset of Community Value under the Localism Act 2011.

Behavior of bats at wind turbines

21 October 2014: PNAS vol. 111 no. 42 : Bat fatalities at wind turbines peak during low-wind conditions in late summer and autumn and primarily involve species that evolved to roost in trees. Researchers discovered previously undescribed patterns in the ways bats approach and interact with turbines, suggesting behaviors that evolved at tall trees might be the reason why many bats die at wind turbines.
