Annual GB mammal roadkill survey

Public asked to keep an eye on Britain’s animal kingdom

July 2012. In the 60 years of Queen Elizabeth II’s reign, mammal populations in Britain have undergone many changes. While some, such as rabbits and foxes have grown in numbers over the decades, other iconic native species such as the red squirrel and hedgehogs have suffered a dramatic decline. Mammals on Roads, an annual survey run by the People’s Trust for Endangered Species (PTES), allows motorists, especially families travelling together by car, to record sightings of any mammals, dead or alive, that they spot from their vehicle, contributing towards the charity’s efforts to monitor the changing state of Britain’s mammals.

Help with the survey

Wildlife enthusiasts can complete the survey via a printed pack or by downloading the Trust’s free Mammals on Roads app onto their iPhone. The app makes it easier to take part in the survey on the move: the location of sightings and the routes of participants’ journeys are recorded using the inbuilt GPS of iPhones. The information captured is then sent to the Mammals on Roads database and analyzed by wildlife experts at PTES. Journeys that are repeated along the same route year on year especially provide important scientific data on changing populations.

1 million mammals killed on UK roads every year

PTES Surveys Officer David Wembridge says: “It is a sad fact that around one million mammals are killed on UK roads each year. However, roadkill provides wildlife experts with clues about the state of wild animal populations, as the proportion of dead animals relates to the number of those alive in the wild. Since the launch of Mammals on Roads in 2001, volunteers have surveyed over three-quarters of a million kilometres of road along the length and breadth of Britain. We hope that with the availability of the iPhone app in addition to the paper-based survey, even more people will take part and help us by surveying the country’s immense road network for signs of wildlife. In the last sixty years, our mammal populations have undergone huge changes, underlying the need for monitoring to in conservation.”

This Jubilee year marks the twelfth anniversary of the survey; continuous monitoring each year is vital to help the Trust build a more complete picture of the state of the UK’s wild mammal populations. A review of the results from Mammals on Roads provided evidence that the hedgehog population had declined by a quarter over the last decade, leading PTES to initiate a campaign to protect the endangered animals.

Mammals on Roads is an annual survey and runs through July, August and September. The app, which was developed by Dr Brock Craft of the London Knowledge Lab and Dr Adam Talcott of Atomic Powered, is available to download for free at the App Store.

How have the top mammals spotted on Britain’s roads fared?

Rabbit (Oryctolagus cuniculus)

The rabbit population in 1952 was around 100 million (40 million were culled each year for meat and fur); the following year, myxomatosis was introduced and by 1955, 99% had been killed. Thirty years later, the population had grown to 20 million and today it is almost twice that (38 million).

Hedgehog (Erinaceus europaeus)

Burton, in 1969, estimated the population in the early 1950s to be 36.5 million in arable and pastoral land areas, although this was based largely on guesswork. Since then, there has been a steady decline. In 1995, the population in Great Britain was estimated to be 1.5 million, but over the last decade, counts of hedgehogs in Mammals on Roads have fallen by a quarter.

Squirrel (Sciurus)

Grey squirrels were introduced throughout the 19th and start of the 20th centuries. Their range expanded rapidly between 1930 and 1945. In the 1950s, a bounty system failed to reduce grey squirrel numbers or prevent their spread. By the early 1960s, only parts of Cumberland, East Anglia, north Lancashire and Westmorland remained largely uncolonised in England.

Badger (Meles meles)

In 1952, there were more badgers than there had been fifty years earlier, but in the 1960s and ‘70s, numbers fell as a result of continued persecution and the effect of insecticides such as dieldrin. The first legislation to protect badgers specifically was the Badgers Act 1973, which prohibited badger digging for sport. It was followed by the Protection of Badgers Act 1992, and from the 1980s, the population has increased from about 190,000 to 300,000 today.

Fox (Vulpes vulpes)

Fox numbers in 1960 were very low, perhaps as a result of the loss of rabbits from myxomatosis, but the population recovered over the next thirty years and in 1990, the number of foxes killed per square kilometre was four times that killed in 1946 on the same estates. Since the 1990s, numbers have changed little.

From daily The Morning Star in Britain today:

Rapper starts hunger strike

MOROCCO: Rap artist Mouad Belghouat has gone on hunger strike to protest at prison conditions.

His brother Aderrahim said he began the strike on Monday because he was forbidden from using the phone, was harassed by other prisoners and had his belongings “constantly” searched by guards.

Mr Belghouat was convicted in May of showing contempt for public servants because of one of his songs.

Cave paintings by Neanderthals?

By Philip Guelpa:

Did Neanderthals create cave art?

10 July 2012

A newly published article in the journal Science (Pike et al, 15 June 2012, “U-Series Dating of Paleolithic Art in 11 Caves in Spain”) indicates that Paleolithic cave art in Europe dates even earlier than previously known, to at least 40,800 years ago. This is only a few thousand years, at most, after the earliest documented appearance of anatomically modern humans on the continent and at least 4,000 years older than the previous estimates for the earliest cave art in Europe. Tests run on samples from the 11 caves identify the earliest image as a red disk dating to 40,800 years ago, followed at 37,300 years by a hand stencil, and a claviform-like (key-like) symbol at 35,600 years.

Over the following millennia, artistic representations painted on cave walls developed tremendously in variety and sophistication, including a whole range of abstract symbols as well as exquisitely life-like animal representations, which demonstrate a fully human intellectual and aesthetic capability. However, these early simple designs, assuming that they do indeed predate the more elaborate images, may illustrate an aspect of the artistic tradition that modern humans brought with them when they first migrated out of Africa. The newly applied dating technique uses the ratio of radioactive uranium to thorium in the calcium deposits (calcite) that have formed on the cave walls after the paintings were created. Uranium gradually decays into thorium at a predictable rate. Once a calcite deposit is formed the initial ratio of the two elements will progressively shift; thus the older the specimen the greater the proportion of thorium to uranium.

This technique is more accurate for the time range in question than radiocarbon dating of organic compounds in a painting’s pigment, since the latter technique becomes unreliable for dating materials more than about 30,000 years old. Since the uranium-thorium technique dates material deposited over the paintings, it gives only the latest possible date. The actual age of the paintings may be even older. Given the time frame of this earliest known cave art, the authors of the Science article suggest the possibility that some of this work may have been created by Neanderthals (also spelled Neandertals) rather than by modern humans. If true, this would tend to further reduce the previously postulated evolutionary distinction between Neanderthals and modern humans. However, the proposal is controversial and, at this time, speculative.

Nevertheless, the corporate media and some scientists have been quick to sensationalize it. These accounts play up the novelty of the idea that Neanderthals, once thought to be hulking, sub-human brutes, actually had the intellectual capacity and aesthetic sense to create art, which is taken to indicate abstract, symbolic thought, while minimizing the tentative and so far very weak scientific basis on which this hypothesis is based. Neanderthals had been present in Europe at least 150,000 years ago and, so far, there is no evidence of cave art over more than two thirds of that time period. Currently available data indicates that modern humans only arrived on the continent sometime between 40,000 and 45,000 years ago. Neanderthals became extinct or were genetically absorbed into the modern human population within 10-15,000 years of the latter’s arrival. Some recent research suggests this may have happened even more quickly. While there may have been sufficient genetic compatibility for successful mating, as recent genetic research seems to suggest, the overwhelming preponderance of data currently available indicates that Neanderthals, at least prior to the appearance of modern humans, had very limited artistic capabilities, confined to small items of personal adornment.

Unfortunately, the stratigraphic integrity of the principal source of this supposed evidence, Grotte du Renne at Arcy-sur-Cure in central France, is in question. Modern humans also occupied the cave, so the separation between artifacts associated with each group cannot be confirmed.

Similar objects are clearly associated with undisputed sites of modern human occupation. There is also evidence that Neanderthals employed red ocher (iron oxide) pigment, which is often used in cave paintings, in some contexts, such as the decoration of burials. However, their technological capabilities, as illustrated by stone tools, while exhibiting a certain degree of sophistication, appear to have been markedly inferior to those that modern humans brought with them from Africa. By contrast, there is gradually accumulating evidence that anatomically modern humans had by the time of their spread out of Africa already developed intellectual and aesthetic capabilities beyond those so far documented among Neanderthals. For example, new dating of a cave site in southern Germany reveals that modern humans were making flutes out of bird bone and mammoth ivory at about 42,000 to 43,000 years ago, very soon after their initial arrival on the continent.

Recent research at Blombos Cave in South Africa indicates that modern humans were already exhibiting abstract, symbolic thought, as represented in a variety of objects, including pieces of ochre engraved with abstract designs and beads made from shells, at least as early as 75,000 years ago. Evidence that modern humans used red ocher as a pigment has been found at Qafzeh Cave in Israel dating back to 90,000 years ago. Evidence from other parts of the world suggests that as they spread out of Africa modern humans carried an already established artistic tradition wherever they went. Petroglyphs (rock engravings) appear in Australia at roughly 40,000 years ago. As in Europe, this artwork dates to shortly after the likely first arrival of the humans on the continent. Unless new dates for European cave art push its origins even earlier, well before the arrival of modern humans on the continent, it would appear that the hypothesis that Neanderthals painted in caves remains unproven at this time.
