Plant and animal species are shifting their geographic ranges and the timing of their life events – such as flowering, laying eggs or migrating – at faster rates than researchers documented just a few years ago, according to a technical report on biodiversity and ecosystems used as scientific input for the 2013 Third National Climate Assessment.

The report, Impacts of Climate Change on Biodiversity, Ecosystems, and Ecosystem Services, synthesizes the scientific understanding of the way climate change is affecting ecosystems, ecosystem services and the diversity of species, as well as what strategies might be used by natural resource practitioners to decrease current and future risks. More than 60 federal, academic and other scientists, including the lead authors from the U.S. Geological Survey, the National Wildlife Federation and Arizona State University in Tempe, authored the assessment.

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.

Collaring Tapirs – Elephant look-alikes – to Help Them Survive

EAST LANSING, Mich. — A team of Michigan State University researchers will soon be heading into the rainforests of Nicaragua to help an endangered species known as a Baird’s tapir co-exist with local farmers whose crops are being threatened by the animals.

The animals were thought to be extinct in that part of the world until just two years ago when the MSU team discovered them still living there through the use of “camera trapping” – the setting up of still and video cameras in order to “capture” the animal. (more…)

Sharks: Bad Creatures or Bad Image?

EAST LANSING, Mich. — Historically, the media have been particularly harsh to sharks, and it’s affecting their survival.

The results of a Michigan State University study, appearing in the current issue of the journal Conservation Biology, reviewed worldwide media coverage of sharks – and the majority isn’t good.

Australian and U.S. news articles were more likely to focus on negative reports featuring sharks and shark attacks rather than conservation efforts. Allowing such articles to dominate the overall news coverage diverts attention from key issues, such as shark populations are declining worldwide and many species are facing extinction, said Meredith Gore, MSU assistant professor of fisheries and wildlife and the School of Criminal Justice.

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…)

Precautions for Tick-Borne Disease Extend “Beyond Lyme”

Save the tick that bites you: it may not be the one you think

This year’s mild winter and early spring were a bonanza for tick populations in the eastern United States. Reports of tick-borne disease rose fast.

While Lyme disease is the most common tick-borne disease in the Northeast and Upper Midwest, new research results emphasize that it is not the greatest cause for concern in most Southeastern states.

The findings are published today in a paper in the journal Zoonoses and Public Health. (more…)

Blanket Bogs Need Protection from Climate Change

Blanket bogs, which provide vital habitats for a unique range of plants, birds, small mammals, reptiles and amphibians, are at risk of declining as a result of climate change.

Research by the Universities of Exeter and Bristol in the UK and Macquarie University in Australia, published in the journal Nature Climate Change, shows for the first time how rising temperatures will threaten these sensitive ecosystems.

The study highlights the urgency of developing a plan to protect these important habitats.

Found in wet, coastal areas of high latitude regions, blanket bogs cover around 700,000 hectares of land in the UK, much of it designated as a Site of Special Scientific Interest (SSSI). Blanket bogs are found in the north and west of the UK, extending from Devon in the south to Shetland in the north, and it has been estimated that 10 to15 per cent of the world’s blanket bog occurs in Britain. As well as being crucial in supporting wildlife, blanket bogs also capture and store large amounts of carbon, helping to mitigate against climate change, and reduce the risk of flooding, by slowing down water flow. With some blanket peat being over 9,000 years old, they also hold historically-significant archaeological material. (more…)

New Findings of Endangered Birds at Hakalau Forest National Wildlife Refuge Give Hope to Recovery Efforts

HAWAI’I ISLAND, Hawai‘’— Three of Hawai’i Island’s rarest endangered forest birds have been detected at lower elevations of Hakalau Forest National Wildlife Refuge for the first time in 30 years.

The rediscovery of the three endangered species at lower elevations than expected was part of a joint U.S. Fish and Wildlife Service and U.S. Geological Survey project on the potential impact of climate change on avian disease. All three species are believed to be highly susceptible to mosquito-transmitted diseases, limiting their distribution to the cooler, higher elevations of the refuge. These new observations significantly extend the current known range of these species at the refuge. (more…)
