Let’s hear it for switchgrass

Filed under: Technology, Environment, Biodiversity — Rick Eyre @ 2:44 pm

“We’ll also fund additional research in cutting-edge methods of producing ethanol, not just from corn, but from wood chips and stalks, or switch grass.”
- GW Bush, State of the Union Address, 31.1.06

And there you have it. GWB’s follow-up to his 2005 asbestos moment.

More on the Great Switchgrass Debate from the Kansas City Star, Agriculture Online, Grist, the Motley Fool. Here’s a study from Auburn University adopted by the US Bioenergy Feedstock Information Network. And yes, you can buy some from the Digging Dog Mail Nursery of Albion, California.

Panicum virgatum indeed!

Tribal extinction in the Andamans?

Filed under: Human Rights, Biodiversity, Tsunami — Rick Eyre @ 10:07 am

The Andaman and Nicobar Islands are among the hardest hit locations as a result of Sunday’s earthquake and tsunami, being close to the epicentre of some of the quakes. There are fears that some or all of the races indigenous to the archipelago, namely the Great Andamanese, Onges, Jarawas, Sentinelese and Shompens, may have been wiped out entirely.

Wednesday afternoon however, India’s Union Defence Minister Pranab Mukherjee said that the Ongi people had escaped to higher ground and were safe, and that some Sentinelese and Jarawas were known to have survived. Further information of course is still very very sketchy.

The Indian government website of the Andaman and Nicobar Islands has information about the indigenous tribes. See also this ANI report on the Union Defence Minister’s comments.

Where Are All the Dead Animals? Sri Lanka Asks

Filed under: Biodiversity, Tsunami — Rick Eyre @ 12:03 am

COLOMBO (Reuters) - Sri Lankan wildlife officials are stunned — the worst tsunami in memory has killed around 22,000 people along the Indian Ocean island’s coast, but they can’t find any dead animals.

What not to buy for Christmas

Filed under: Biodiversity, Christmas — Rick Eyre @ 6:29 pm

Leave that shahtoosh alone. And no we’re not buying a tiger cub for the kids. The World Wildlife Fund has released its list of Ten Things Not To Buy For Christmas. (Why they’ve left their Christmas anti-shopping till December 21 is beyond me.)

Full text of the WWF press release follows:

Ten things not to buy for Christmas

Gland, Switzerland – Looking for that elusive gift or sumptuous dining experience as the festive season approaches in many countries?

WWF says that by avoiding certain items and carefully sourcing your presents, you can avoid having a detrimental impact on the planet’s natural resources and a guilt free holiday season.

“It’s about being aware what you buy, and the impact it can have on species and the environment,” says Dr Susan Lieberman, Director of WWF’s Global Species Programme.

“Some people have no idea what is legal or illegal. Our advice is based on threats to wildlife and the environment from unsustainable trade and consumer demand.”

Beluga Caviar – If buying, buy carefully. While nothing is more evocative of luxury than black caviar, be aware that the sturgeon of the Caspian Sea could face extinction due to unsustainable and illegal plunder for their roe. Purchase caviar only from shops, only in sealed jars and, most importantly of all, make sure the jar or tin is sealed with a CITES (Convention on International Trade in Endangered Species) label.

Tigers/Tiger products – Don’t buy. Owning a tiger as a pet, as well as tiger skin rugs and coats is gaining kudos in some elite circles. There are around 5,000 tigers left in the wild and populations are under immense pressure from habitat loss and poaching. All international trade of tiger products, whether used in traditional Asian medicine, as souvenirs or for “good luck” charms, is illegal.

Ivory products – Don’t buy ivory trinkets. The illegal trade in elephant ivory is a continuing problem world-wide. If an elephant is poached for its ivory, chances are great that the ivory will end up in a market in Africa or Asia. From there, trade moves through illegal channels into other markets in North America and Europe. The continuing existence of illicit ivory markets, particularly in Africa and Asia, remains one of the greatest threats to elephants today, particularly in West and Central Africa.

Turtle shell products – Don’t buy. Six of the seven species of marine turtles are endangered or critically endangered, and the outlook is increasingly grim. In the Pacific, leatherbacks are heading for extinction, fast, and in the Mediterranean, green turtle numbers have plummeted. All international trade in marine turtle products is banned, so avoid those hair clips, bracelets and souvenirs you may see on your travels.

Shahtoosh – Don’t buy. Shahtoosh is a high fashion scarf woven from the hair of the Tibetan antelope. To obtain the wool, the antelope has to be killed. Though some traders may tell you the wool can be collected from bushes which the animal has brushed against, that’s false. Due to poaching, the population of this species is dwindling and the species is on the endangered list. Buy a wool pashmina shawl instead.

Coral products – Buy very carefully. Slow growing and long living corals are collected for jewellery and ornamental purposes, but intensive collection threatens the reef . For example, red coral, a popular coral found only in the Mediterranean, and used for jewellery, has become locally extinct due to over-harvesting. If you plan to bring it home from overseas, make sure you find out if you need a CITES permit. If buying at home, ask the retailer if the coral was imported with the necessary CITES permit.

Crocodile skin and snake skin products – Buy carefully. If you like those fancy cowboy boots or little evening bag, be aware that some native wild populations of crocodiles and snakes are in dire straits and critically endangered. While it’s likely your belt, bag or shoes comes from captive bred populations, not wild ones, check that your product has a CITES permit before you part with your cash.

Cod – Buy carefully. Cod stocks have plummeted and are on the verge of collapse in the North Sea, Irish Sea and waters west of Scotland. There is also a huge problem with illegally caught cod. Only the stocks around Iceland and the Barents Sea are healthy and relatively well managed. Enquire at your local supermarket or retailer about the source and legality of cod for sale.

Cactus – Buy carefully. The prickly plant trade may be popular, but watch out. There is a flourishing illegal trade which is wiping out native populations, particularly from Mexico. Some species are totally banned from international trade and some require an import permit. Whilst the great majority of cacti for sale have been artificially grown in nurseries and are legal, cacti that are imported into a country do require a permit. So, if in doubt, check the paperwork!

Electrical items – Buy smart. If buying large electrical goods like stereos and televisions buy ones that can be turned off and do not just sit on standby. Often they use as much as 40 percent of their electricity in standby mode.

Biodiversity websites I’m watching

Filed under: Technology, Biodiversity — Rick Eyre @ 12:51 pm

A spinoff of teaching Adara about animal and plant life is that I have started to pay more attention to biodiversity on the web. I do a Yahoo! news photo search for her most mornings. Common search criteria we use are zoo, monkey, orangutan or kangaroo.

The IUCN (International Union for Conservation of Nature and Natural Resources) 2004 Red List of Endangered Species was released in November, and there is a searchable database on the Red List website.

The New South Wales National Parks and Wildlife Service has an Atlas of NSW Wildlife, which contains a searchable database of species of flora and fauna sighted in various locations of New South Wales.

A real beauty, however, is Animal Diversity Web, produced by the University of Michigan Museum of Zoology. If any website deserves to be called the IMdB of the Animal Kingdom, the ADW is it.

Let’s go looking for endangered species of animal in the area where I live. I’ll go the NSW Wildlife Atlas and search for endangered species of fauna recorded since 1980 in the Marrickville local government area. This gives me three results, the Ptilinopus superbus (superb fruit-dove), the Xanthomyza phrygia (regent honeyeater), and the Litoria aurea (green and golden bell frog).

Sightings of the green and golden bell frog in the Marrickville LGA since 1980.From the results page we can then call up a map which shows the places where the species have been sighted within the region. I can’t link to the result maps as they are dynamically generated, but an excerpt from the map of frog sightings can be seen at right, with the locations indicated with the pink dots (we live a little to the north of the O in Newtown).

Let’s focus on the green and golden bell frog for now. We go to the IUCN Red List search page and look for Litoria aurea. The search results lead us to the IUCN’s species page, and see that the frog has been classified as vulnerable since 2001. A lot of background information on habitats, threats, and required action.

ADW is thorough, but nonetheless incomplete: if we go to the Pelodryadinae (Austro-papuan tree frogs) subfamily, we can see other frogs listed in the Litoria genus, but not Litoria aurea. At best, we can expect photos, sound bites and even movies of certain species on ADW.

Finally, a good old Google search for Litoria aurea leads us to the marvellous frogs.org.au, run by the Amphibian Research Centre. Listen to an MP3 of the frog’s croak.

Adelaide zoo snaps

Filed under: About Now, Biodiversity — Rick Eyre @ 11:47 pm

Di, Adara and a quokka.Some photos from our visit to the Adelaide Zoo during our recent holiday in South Australia are on-line now in my little-publicised gallery site.

Among creatures depicted: zebra, lion, meerkat, siamang, quokka, tapir, tortoise, even the odd chook or two. Some of my pics didn’t come out too well, as it was raining for most of our visit and the lens got a bit wet. Among the deleted photos was my picture of two firefoxes in their enclosure - unfortunately I ended up with a very good close-up of the wire fence!

Still to go on-line, we have some photos from the Tasmanian rainforests taken during our honeymoon in April 2001. One pic of a couple of pademelons was featured on my www.rickeyre.com home for a long time, but most of the others have never been published. I’ll do so when I get time.

Homo floresiensis the Hobbit

Filed under: Biodiversity — Rick Eyre @ 5:46 pm

Much ado in the media today about the discovery of a extinct “hobbit”-like human species which lived in Indonesia about 18000 years ago.

Homo floresiensis is the name given to this new species. Reports from National Geographic News (they apparently have a program coming up on the subject) and Nature magazine.
