Whale’s diet revealed in its doo-doo

* 01 December 2007

* Magazine issue 2632

Want to find out what whales eat? There’s no need to cut them open, just wait until they relieve themselves.

One of the reasons given by the Japanese government for its “scientific” whaling programme is to learn more about the animals’ diet. Now Stacy DeRuiter at the Woods Hole Oceanographic Institution in Massachusetts and her team have developed a way of investigating diet by identifying mitochondrial DNA from the remains of the prey in a whale’s faeces.

The team has collected samples from several cetacean species and discovered, for example, that faeces from Blainville’s beaked whale contain DNA evidence of bony fish, including gulper eel. It had been thought to dine primarily on squid.

“It’s now certainly the case that we can get as good diet information from DNA analysis of faeces as we can from dead whales – probably better,” says Simon Jarman of the Australian Antarctic Division …

Rare cicada, rare beetle, in Cornwall, England


Ledra aurita

From Wildlife Extra:

Two unusual finds in Cornwall

November 2007. A local beetle expert, Dr Ian McClenaghan, has found a specimen of one of the UK’s rarest beetles Hypulus quercinus (Quensel) on a Cornwall Wildlife Trust reserve – Cabilla and Redrice Woods. This is the first ever recorded sighting in Cornwall.

Dr McClenaghan said, ‘The species is associated with red rot in dead wood and I am not aware of anyone having spotted it in the UK for a number of years. Probably about one per year is discovered in Britain. …

Meanwhile, further east in the county the Launceston Parish Wildlife Recording Group have made an interesting discovery whilst recording moths in the parish of Lezant. The group has discovered an unusual looking leaf hopper Ledra aurita (Linnaeus).

This is a cicada species.

Exhibition about sabre-toothed cats


There will be an exhibition about sabre-toothed cats in the natural history museum in Leiden, the Netherlands.

It will be from 1 December till 6 January 2008.

Sabre-toothed cats arose several times during feline evolution. Not all species are closely related.

The exhibition is about Homotherium latidens. Until recently, scientists thought that species had become extinct 300,000 or 400,000 years ago.

However, on 16 March 2000, a lower mandible was found in the North Sea, near the Bruine bank. It was only 28,000 years old; so, it proved the older theory wrong. Then, during the Ice Age, the southern part of the North Sea was still land.

Rare Kirtland’s Warbler returns to Canada


This video from the USA is called In Search of Kirtland’s Warblers.

Conservationists “thrilled” as Kirtland’s Warbler returns to Canada

30-11-2007

Bird Studies Canada (BirdLife’s Canadian co-Partner) has expressed delight at news that a pair of Kirtland’s Warbler Dendroica kirtlandii have bred in Canada – the first in over 60 years.

The birds were found at a Canadian Forces Base in eastern Ontario and, although eggs in the nest were unviable, the discovery has provided useful data for scientists researching the distribution of this species, listed globally as Near Threatened by BirdLife.

Kirtland’s Warbler does not normally breed outside of Michigan in the US, but this year in addition to the nest in Ontario, others were found in Wisconsin.

Extensive habitat loss across its northern breeding range saw the warbler’s population drop to fewer than 200 males in the 1970s. More recently numbers have been seen to recover: almost 1,500 singing males were recorded in Michigan in 2006.

It seems Kirtland’s warblers are back from the brink of extinction: here.

Picasso’s painting Massacre in Korea


Pablo Picasso, Massacre in Korea

By Martin Shaw:

Pablo Picasso‘s ‘Massacre in Korea‘ (1951; in the Musée Picasso, Paris), … is based on a massacre of Korean civilians by US forces at No Gun Ri from 26-29 July 1950, which has remained controversial to this day. Korean survivors claim that they were bombed by the US airforce on 26 July, and subsequently fired on by US soldiers in a tunnel into which large numbers had fled, leading to over 300 deaths.

Half a century later, after an indefatigable campaign by Korean survivors, in 1999 Associated Press reporters found US veterans who confirmed the massacre story. The US Army was finally forced to confront the allegations and established an official investigation into the episode, whose Report of the No Gun Ri Review was published in January 2001. …

Picasso’s painting was doubly controversial in its time. It not only endorsed claims of massacre that were denied by the US. It was also criticised within the French Communist Party (PCF), of which Picasso was a member, for not conforming to a socialist realist style. The painting has never achieved the iconic status of the earlier Guernica (1937), but it has remained one of Picasso’s most explicitly political works, a point of reference in various situations.
