Caviar has lost its national identity. Over the years, caviar-producing wild sturgeon in the Caspian Sea have been poached, smuggled and overfished to the brink of extinction. Sturgeon fishing fell under a series of strict international quotas and in 2008 was subjected to a global ban by the Convention on International Trade in Endangered Species. The only caviar on the market since then comes from tame varieties farmed in concrete basins and cages. The result is a global free-for-all in which caviar’s country of origin has no meaning, and only the best eggs win. - Sepi ⌘ سپی from Bookmarklet
Since sturgeon fishing was banned in the Caspian Sea, Paris’s top purveyors of the delicacy have turned to producers from as far afield as California, Uruguay and China. - Sepi ⌘ سپی

New report reveals scale of declines of UK migratory birds wintering in Africa
Species, such as Whinchat, Common Nightingale, Tree Pipit and Spotted Flycatcher, which winter in the humid zone of Africa – stretching across the continent from southern Senegal to Nigeria and beyond - show the most dramatic declines: the indicator for this group of species has dropped by just over 70% since the late 1980s. This contrasts with species, such as Sand martin, Common Whitethroat and Sedge Warbler, wintering in the arid zone (just below the Sahara desert). These species have fluctuated considerably since 1970, but show a less than 20% decline overall. - Halil from Bookmarklet
One of the most dramatic declines is that of the European Turtle-dove with a decline of 88% since 1995. The following species have also declined over the same period: Wood Warbler, 66%; European Pied Flycatcher, 53%; Spotted Flycatcher, 49%; Common Cuckoo, 49%; Common Nightingale, 43%; and Yellow Wagtail, 43%. - Halil
If wildlife crimes are at the root of this, ie birds being caught in nets during their migration and then sold off as either pets or food delicacies, then the root cause is most likely poverty as some wildlife crimes are driven by poverty. So the question is how do you address that issue, but I'm only speculating that the birds are being trapped during their migratory paths. - Halil

Around the world in 400,000 years: The journey of the red fox - http://phys.org/news...
Around the world in 400,000 years: The journey of the red fox
Now, University of California, Davis, researchers have for the first time investigated ancestry across the red fox genome, including the Y chromosome, or paternal line. The data, compiled for over 1,000 individuals from all over the world, expose some surprises about the origins, journey and evolution of the red fox, the world's most widely distributed land carnivore. - Halil from Bookmarklet
The new genetic research further suggests that the first red foxes originated in the Middle East before beginning their journey of colonization across Eurasia to Siberia, across the Bering Strait and into North America, where they eventually founded the North American population. "That small group that got across the Bering Strait went on to colonize a whole continent and are on their own evolutionary path," Statham said. - Halil

Derived from a naturally occurring insecticide, emamectin benzoate (EMB), and its means of deployment, known as tree micro-injection, it is currently being assessed by the Chemicals Regulation Directorate. - Halil from Bookmarklet
He said: "We tested for wound closure as well as leaf chlorophyll content and fluorescence - these weren't affected. We can inject it at quite high levels without burning the tree." O'Callaghan added: "One application lasts two years, with signs of effect in three-to-four weeks." - Halil

Norfolk boobook - The species is extinct but the owls genes exist in a small hybrid pop still living on the island!
Norfolk boobook - The species is extinct but the owls genes exist in a small hybrid pop still living on the island!
The population of the Norfolk boobook declined with the clearance and modification of its forest habitat, especially the felling of large trees with suitable hollows for nesting in. There was also competition for nest hollows with feral honey bees and introduced crimson rosellas.[5] By 1986 the population had been reduced to a single female bird, named "Miamiti" after a matriarch of the Norfolk Island people.[6] As part of a program to attempt to conserve at least some of the genes of the insular subspecies, two male Southern boobooks (moreporks) of the nominate New Zealand subspecies, Ninox novaeseelandiae novaeseelandiae, were introduced to the island as mates for the female. The males were sourced from the New Zealand subspecies rather than one of the Australian subspecies as it was discovered that it was more closely related to the Norfolk Island taxon.[7][8] Nest boxes were also provided. One of the introduced males disappeared a year after introduction but the other successfully... more... - Halil from Bookmarklet

Cheetahs Prosper: New Study Debunks More Old Myths – Phenomena: Not Exactly Rocket Science
"The cheetah’s life is reputedly balanced on an energetic cliff. Yes, it’s the fastest land animal, capable of going from 0 to 60 miles per hour in a few seconds. But, according to countless nature documentaries, its high-speed chases leave it exhausted and overheated. If it fails to catch a meal, it’s in bad shape to try again. And even if it’s successful, it is easily and frequently driven away from its own kills by more powerful predators like lions or hyenas. The price of super-speed is a teetering existence, spent scrabbling for food and energy. Except, very little of that is true." - Eivind from Bookmarklet

Eagle-Eyed Birds of Prey Help Vultures Find Food - http://www.natureworldnews.com/article...
Eagle-Eyed Birds of Prey Help Vultures Find Food
But the vultures don't just follow the eagles to their next meal. They also use the sharp-beaked eagles as a way to better access food, letting them tear open tough carcasses - a talent that vultures lack - before swooping in and taking it all for themselves. - Halil from Bookmarklet
"Vultures were once the most abundant birds of prey in the world, but their numbers have been hammered in recent decades by habitat loss, inadvertent poisoning, and hunting," said Andrew Jackson, who supervised the research. "Our study shows, as is often the case in the tangled web of ecology, that it is important to consider other species when trying to conserve vultures. In this case, conserving early rising raptors may help to boost the chance that vultures find enough food to survive." - Halil
Sometimes we have a dozen vultures circling the ridge in front of our house, surfing the warm air as it rises up and away. Gorgeous to watch. - Todd Hoff
Extra news: July of last year, roughly 500 vultures died after they ate the pesticide-laced carcass of an elephant that had been killed by poachers in Namibia. It was an example of one poaching technique in Africa that seems to be on the rise: the poisoning of vultures so that authorities won’t be alerted to the location of the crime. http://raptorpolitics.org.uk/2014... - Halil

Adjusting wind power production during migration season saves bats
"With minimal loss in power production—and hence revenue—and with the aid of the bat shield, First State Marine Wind was able to realize a significant reduction in bat fatalities," Firestone said. A great advantage of the bat shield is that "we can program in changes to the cut-in speed that are tied to atmospheric conditions and time of year and time of day so that turbines can be easily adjusted to protect bats," he said - Halil

Photographer with Down's syndrome 'sees the world differently' - http://www.bbc.co.uk/news...
Photographer Oliver Hellowell has Down's syndrome, which his mother says means he sees the world differently to most other people. Oliver's unique way of capturing the natural world has recently gained him a lot of fans. Just over a year ago his mother Wendy O'Carroll set up a Facebook page for the eighteen-year-old's photography. That page now has over ten and a half thousand followers. "It's not just the numbers that have surprised the family, it's the range of people," says Wendy. The page has fans from Brazil to Alaska. Oliver hopes that photography - particularly of birds - can become his full-time profession. - Halil from Bookmarklet

Reserves and parks not enough to protect nature – David Attenborough
But rather than lament the changes, he urged everyone to act. “We know climate change is happening. It is regretted by some but it is also to be embraced. It is causing great changes in the distribution of animnals and birds in the countryside. We must take advantage of that. It is very important that we accept there are things coming in ... We must recognise that new animals and plants are coming in. Others are moving north. We ought to be giving thought to wildlife corridors ... and not think that every new arrival is to be repelled. - Halil from Bookmarklet

Extinctions during human era worse than thought | News from Brown - http://news.brown.edu/article...
PROVIDENCE, R.I. [Brown University] — It’s hard to comprehend how bad the current rate of species extinction around the world has become without knowing what it was before people came along. The newest estimate is that the pre-human rate was 10 times lower than scientists had thought, which means that the current level is 10 times worse. - Halil from Bookmarklet
The new study next examined evidence from the evolutionary family trees — phylogenies — of numerous plant and animal species. Phylogenies, constructed by studying DNA, trace how groups of species have changed over time, adding new genetic lineages and losing unsuccessful ones. They provide rich details of how species have diversified over time. - Halil

Most of the fish and birds that she's studied have come from Lake Erie. Mason and her students began collecting fish in January by going to local ice fisherman; Mason wound up with a lot of perch, since that's what they were catching. Through the spring, Mason and her student assistants examined 75 perch and 17 cormorants, a type of water bird. In both cases, a high percentage of the subjects had plastics in their gastrointestinal tracts, Mason says. - Halil from Bookmarklet

UK Professor Tom Curtis : I make no apologies for putting micro-organisms on a pedestal above all other living things, for if the last blue whale choked to death on the last panda, it would be disastrous but not the end of the world. But if we accidentally poisoned the last two species of ammonia-oxidisers, that would be another matter. It could be happening now and we wouldn't even know - Halil from Bookmarklet

Butterfly wings lift Greater Taichung students to victory - Taipei Times
"Two juniors from Taichung Municipal Hui-wen High School recently claimed the top prize at this year’s Shizuoka Kita Youth Science Engineering Forum after unlocking the secret to why Japanese white butterflies (Pieris rapae crucivora) dominate the white butterfly (Pieris canidia) population in Taiwan. Yuan Li-yun (袁笠芸) and Hsiao Pei-wan (蕭佩宛) said that the Japanese white butterflies account for up to 90 percent of the nation’s white butterfly population." - Jessie from Bookmarklet
"To determine why, the girls captured more than 100 white butterflies and put female Japanese and Taiwanese butterflies in separate ziplock bags to block the scent of insects’ pheromones. Even without being able to scent the females, the male Japanese butterflies were still drawn to the Japanese females, which prompted the pair to infer that the males rely mainly on vision, not scent,... more... - Jessie
