‘The bliss of a quiet period’: lockdown is a unique chance to study the nature of cities

The Guardian reports on two stories about the changes we’re seeing to wildlife as a result of Covid-19 lockdown. Check out at least one of these stories if only to see the unusual, but beautiful sight in their photo of a herd of fallow deer graze on the lawns of a housing estate in east London (sorry FNW don’t have permissions to copy it here).

The first reports deer roam city streets and hedgehogs can safely cross roads… but a radical policy shift is needed to protect wildlife in future, say campaigners. Britain’s wildlife may be thriving during the current lockdown but its long-term future is looking bleak, according to leading conservation organisations. Nikki Williams, head of campaigns at the Wildlife Trusts, said: “The current crisis means nature is losing out, because many organisations are having to scale back important work caring for special places, which they usually do with the vital help of thousands of volunteers.” 

The other reports empty streets and skies let the birds be heard and leave animals free to roam as well as allowing scientists to examine how humans change urban biodiversity.

Invasive grey squirrels carry a parasite that makes their native red cousins sluggish and threatens to further reduce their numbers

The Daily Mail reports experts from Italy and Belgium studied populations of red and grey squirrels. Grey squirrels pass parasites onto red squirrels that make them forage slowly. The presence of greys also alters the reds’ relations with their natural parasites. The team said that the pressure faced by the reds may lead to their extinction.

Bears should be reintroduced into British countryside one day, says new head of Wildlife Trusts

The Telegraph reports bears should be reintroduced into the British countryside one day, the new head of the Wildlife Trusts has said, as he argues the loss of the species is as significant as if we lost the works of Shakespeare.

Dr Craig Bennett, who was previously the CEO of Friends of The Earth, now starts as the chair of the wildlife charities and has been enlisted to turn the nature reserves into a campaigning force.

On the face of it, mice can show their emotions just like us

The Times reports more than a century ago Charles Darwin broached the idea that animals could display emotions as plainly as people do. The notion has been controversial. Does a hang-dog expression really show that a canine is ashamed? Will a cockatoo in a state of ennui look crestfallen? Researchers have offered support for Darwin’s proposal by training a computer to decipher expressions in mice.

In a paper published in Science, they showed that the countenance of a mouse can be read like that of a human. Mice grimace in pain and look forlorn when nauseous. It is also possible to tell if they are afraid or delighted.

Nadine Gogolla of the Max Planck Institute of Neurobiology, who led the study, said: “A happy mouse tends to move every part of their face towards the stimulus, towards the front. Their face looks almost a bit squished. Their ears lay down and point forward; their nose moves towards the mouth. And they stick their tongue out and smack their lips.”

Nottingham Trent University study to assess impact of traffic on hedgehogs

The BBC reports researchers are investigating how many hedgehogs are killed on our roads in a bid to help the UK’s declining population. A Nottingham Trent University team will also study whether tunnels under roads could reduce the number of deaths. Experts believe the animals are struggling with lost habitats, increased competition and traffic. Researchers hope this study could help stop the creatures’ decline and provide guidance for planners and developers. 

Commuting seal and dolphins swimming farther south than ever, wildlife experts say

The INDEPENDENT reports more jet-skiers, kayakers, boat-trippers and drones are alarming dolphins and seals. Wildlife experts have celebrated “extraordinary” sightings of Scottish bottlenose dolphins off the Yorkshire coast – thought to be the farthest south that they have ever been spotted on the UK’s east coast. They have also discovered a seal “commuting” between the Isle of Man and Cornwall to have pups and search for food. But the discoveries – among the success stories for UK marine life in 2019 – were marred by finding that a greater number of jet skiers, kayakers and boat-trippers, as well as drones, were causing the marine mammals to panic. 

Beavers to be released in plan to ease flooding and aid biodiversity

The GuardianThe Times, and The Telegraph report three families of beavers are to be introduced on land managed by the National Trust as part of plans to ease flooding and improve biodiversity. Two Eurasian beaver families will be released next spring into enclosures at Holnicote estate on Exmoor, in Somerset, and another group will arrive at Valewood on the Black Down estate, on the border of West Sussex and Surrey.

Beavers were hunted to extinction 400 years ago in the UK for their fur, meat and scent glands. In recent years there has been a series of controlled reintroductions, including one by the government in the Forest of Dean, in Gloucestershire, as solutions are sought to tackle flooding.

Badger culls risk increased spread of TB to cattle, study finds

BBC NEWS reports culling badgers drives them to roam further afield, allowing them to disperse tuberculosis over a larger area, new research suggests. The culls might thus increase the risk of TB spreading to cattle, the scientists behind the study warn. The review urged the government to explore alternative approaches to culling. It was led by zoologist Sir Charles Godfray, from Oxford University.

State of Nature Report: UK is in danger of losing a quarter of its mammal population, major wildlife report says

THE TELEGRAPHBBCTHE TIMESINEWSINDEPENDENTCHANNEL 4 NEWS report the Wild Cat and Greater Mouse-eared Bat are among those species teetering on the edge of disappearing, according to the State of Nature Report 2019, the first of its kind conducted in partnership with the government. Other mammals in decline include the European Watervole, the Eurasian beaver, the European hegehog, the Orkney vole and the hazel dormouse.

Nature is in decline, the wide-ranging survey has found, and 41 per cent of UK species studied have noticeably fewer numbers than when rigorous scientific study began in the 1970s. Additionally, 15 per cent of species – nearly 1,200 – are threatened with extinction from Great Britain, because of intensive agriculture and climate change.
