Poaching, climate change cause sharp decline in reindeer population in Siberia (downtoearth,)

Krasnoyarsk Krai region in northern Siberia is one-fourth the size of Canada. Cruelty against reindeer in the north of Krasnoyarsk region is becoming more evident with each passing day as poachers adopt novel methods to kill. Going by the statistics, the current population of wild reindeer has come down to anywhere between 400,000 and 500,000, which is a stark decline from one million in the year 2000.

The reindeer population in Taimyr Peninsula (administrative part of Krasnoyarsk region) is the largest wild herd in the world, but a new projection stokes fear of a further decline in population to as low as 150,000 in 2020.

Poachers, reportedly, shoot reindeer in the head from boats when they cross rivers on a seasonal migration from Evenkia to the Taimyr Peninsula. The corpses are then dumped along the Khatanga River. The poachers also chase reindeer on snowmobiles. Pregnant females carrying embryos weighing 3-4 kg often suffer miscarriages. Mass abortion has been reported by veterinarians.

In the last 12 years, wildlife rangers have also witnessed mass mortality of newborn calves.

According to Leonid Kolpashchikov, head of the scientific department of Taimyr Nature Reserve, “The small number of rangers are not able to control hunting of wild reindeer, which is carried out with violations to timing, amount and methods. Poaching is 'out of control' from the Yamal peninsula to Yakutia.” While the official hunting quota is 40,000 reindeer, the poachers kill 120,000 a year. Moreover, poaching occurs in spring, when hunting is technically banned.

Commercial aspect

Selling the antlers of wild reindeer is a lucrative option for poachers. Antlers are seen in some Asian countries, including China, as a remedy for strengthening bones and tendons and they are also believed to increase human sexual performance.

Medications from antlers are used for rapid recovery from illness, accelerate wound healing, merge bones, strengthen immune system and reduce the risk of cancer. Reindeer tongue is served as a delicacy.

In Dudinka, a port on the Yenisei River, poachers obtain 'fake certificates' claiming that antlers were obtained from domestic reindeer herds. Then the antlers are exported to China and South Korea.



“The small number of rangers are not able to control hunting of wild reindeer, which is carried out with violations to timing, amount and methods"


According to the department of veterinary medicine in Taimyr, between February and August 2015, some 61 tonnes of antlers were produced from supposedly domestic reindeer. In 2016, only in Khatanga and Khet in east Taimyr, some 20 tonnes of antlers were produced.

Role of climate change

While the human cause behind the slump in reindeer numbers is clear, Andrey Petrov, a researcher from the University of Northern Iowa, also points to climate change as a key factor for decline in reindeer population.

Reindeer migrate annually and return to same places: a winter area, a calving site and a summer area. Driven by warmer temperatures, harassment by mosquitoes and other related climate factors, Taimyr herd has been lately shifting towards the north and east. This has increased cases of drowning, especially among calves, since the frozen rivers (Khatanga being one of them), which used to freeze up in late September–early October and breaks up in early June, now open earlier than expected. Thus, the herd has to swim across them rather than walk.

Moreover, the trek from calving areas to new summer ranges is also longer than in the past, which proves too difficult for some of the calves.

Besides climate change, revisions to old Soviet-era hunting regulations are another reason. Since bounties are no longer paid for unlimited wolf kills, the growing number of wolves results in more reindeer deaths.

NGT terminates chairmen of pollution control boards in 10 states (downtoearth,)

Cracking the whip on 10 State Pollution Control Boards (SPCBs) for ad-hoc appointments, the National Green Tribunal has ordered the termination of Chairpersons of these regulatory authorities. The concerned states are Himachal Pradesh, Sikkim, Tamil Nadu, Uttarakhand, Kerala, Rajasthan, Telangana, Haryana, Maharashtra and Manipur. The order was given last week by the principal bench of the NGT, chaired by Justice Swatanter Kumar. The recent order of June 8, 2017, comes as a follow-up to an NGT judgment given in August 2016. In that judgment, the NGT had issued directions on appointments of Chairmen and Member Secretaries of the SPCBs, emphasising on crucial roles they have in pollution control and abatement. It then specified required qualifications as well as tenure of the authorities. States were required to act on the orders within three months and frame Rules for appointment [See Box: Highlights of the NGT judgment of 2016 on criteria for SPCB chairperson appointment].

High dose of Vitamin C and B3 can kill colon cancer cells: study (downtoearth)

In a first, a team of researchers has found that high doses of Vitamin C and niacin or Vitamin B3 can kill cancer stem cells. A study published in Cell Biology International showed the opposing effects of low and high dose of vitamin C and vitamin B3 on colon cancer stem cells. Led by Bipasha Bose and Sudheer Shenoy, the team found that while low doses (5-25 micromolar) of Vitamin C and B3 proliferate colon cancer stem cells, high doses (100 to 1,000 micromolar) killed cancer stem cells. Such high doses of vitamins can only be achieved through intravenous injections in colon cancer patients. The third leading cause of cancer deaths worldwide, colon cancer can be prevented by an intake of dietary fibre and lifestyle changes. While the next step of the researchers is to delineate the mechanisms involved in such opposing effects, they also hope to establish a therapeutic dose of Vitamin C and B3 for colon cancer stem cell therapy. “If the therapeutic dose gets validated under in vivo...

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”. The Supreme Court on Friday came close to ordering the government not to deport the Rohingya. It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests. The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach i...
