More garden adventures!

My garden would horrify most real gardeners. Most of what I do to it involves ripping out the ever-encroaching bindweed coming under the fence from neighbours who consider them “ornamental”, and trying to make it as pleasant a place for nature as possible. Here are a few things I found in my garden adventures today. My little camera, as usual, struggles with getting close enough, but they’re just about usable:

Sycamore Galls 500x375

Galls on a Sycamore leaf

These alien-like red structures are called galls. Although they look a little like cocoons, they’re created by the plant itself as a reaction to having eggs injected into the leaf by an insect. It creates the gall to isolate the eggs from the rest of its structure, but the eggs are just as happy in the gall as in the leaf, so it all works out. These ones are probably the work of the Sycamore Gall Mite, Aculops acericola.

Rep Poppy 500x375

Red Poppy

This is a poppy of Genus Papaver. I’m not quite sure of the species. It doesn’t look much like the corn poppy we associate with Flanders field, with the flower being about 6 inches across. It looks a bit more like the Oriental Poppy, but that doesn’t look quite right either. There’s over a hundred species in Papaver, and most don’t have pictures on the internet. It doesn’t matter that much though, as the insects love these whatever they’re called!

Cuckoo Spit Froghopper Froth 500x407

Cuckoo Spit - Froghopper Froth

My rubbishy camera refused to focus properly on this. It’s knows as Cuckoo Spit in the UK, but for once the Cuckoos are innocent. It is a protective froth of processed plant sap made by the nymph stage of a relative of the aphid known as the froghopper. The froth protects the nymph from predation and drying out.

Spider Babys.

Araneus diadematus, the European garden spider, has been busy in my garden. I spotted this group of bouncing babies having fun on my wheeliebin and thought I’d share!

The focus isn’t perfect, but I think it’s the best my little camera is going to manage as close as I had to get. These spiderlings are little more than a millimetre across each. Click the picture to get a larger version.

I hope you enjoy this International Day for Biological Diversity. Why not have a rummage around your own garden or street, and see what you can find! I’d love to see pictures, especially those of you in distant lands.

This just in: George W. Bush is still a jerk.

From the Telegraph:

The American leader, who has been condemned throughout his presidency for failing to tackle climate change, ended a private meeting with the words: “Goodbye from the world’s biggest polluter.”

He then punched the air while grinning widely, as the rest of those present including Gordon Brown and Nicolas Sarkozy looked on in shock.

Mr Bush, whose second and final term as President ends at the end of the year, then left the meeting at the Windsor Hotel in Hokkaido where the leaders of the world’s richest nations had been discussing new targets to cut carbon emissions.

He’s not even bothering to pretend any more. The world is counting the days til he’s gone, and we can get things back to some degree of sanity.

Seeing as we have no footage of this incident, lets take a trip down memory lane and revisit one of President Bush’s other great foreign diplomacy hits.

Al Gore’s New Slideshow

Recently, at TED, the Technology, Entertainment, Design conference, Al Gore spoke about the challenges facing our world:

I guess it’s too late for him to break into the Democratic nomination now. The remaining Democratic runners have been rather quiet on the most important issue of our time. Hilary Clinton and Republican John McCain even want to suspend petrol tax (18 cents a gallon) for the summer. While that might be a temporary help to low-income drivers, the vast amount of money it would cost would be far better spent on fuel conservation, such as subsidising fuel-economic vehicles, and promoting car-pooling. Not to mention that gas taxes are ringfenced for maintaining road infrastructure, so the long-term cost to the public purse would be far greater than any short-term gain.

Oddly, the idea of a windfall tax on those oil producers enjoying a profit bonanza has not occurred to any of the Presidential nominees. Such a windfall tax could pay for a gas tax holiday, subsidised fuel, and more besides.

Draft Al Gore for President of the World: His Nobel lecture.

Al Gore’s Nobel lecture, in full I hope.

More than ever, we need leaders who take climate change seriously. I’m not talking Kyoto serious, I’m talking “Oh crap oh crap, billions will die if we don’t do something now” serious. It is something of a blessing and a curse for me that I studied some environmental science at UEA, as it leaves me less able than most to blithely ignore the coming storm, and go about my business.

Seriously, as someone with a fair bit of ecologist training, I am shitting myself. Not for my own sake, I’ll get by, but for the sake of a world that I’m really quite fond of, and the sake my my entirely theoretical grandchildren. We need the world to wake up and engage in a bit of constructive panic, or our descendants are going to inherit a pretty bleak post-mass extinction world. The greatly reduced natural diversity might sound boring, but I’m sure the greatly increased occurrence of catastrophic weather events will keep things interesting. This sounds like hyperbole. I wish it was.

Global warming is by no means the only environmental issue we have to deal with. Our air, our water, our food; all have become tainted by novel manmade chemicals that have absolutely no business being in our bodies. Species are dying off at an ever increasing rate. Mostly due to destruction of habitat, or inability to cope with changing climate, but sometimes we’re not even sure why, except that they’re probably reacting badly to one of the cocktail of chemicals they’re being poisoned with.

We need leaders who will grasp all these literally existential threats, and take the massive and momentous steps necessary to address them. The nature of politics, sadly, is that very few are willing to take the pain in the short term that we need to ensure long term prosperity.

Al Gore still hasn’t ruled out running for US President, though he’s leaving it bloody late. Al Gore announcing his candidacy would be the best Christmas present I could get. I’d even pass up an iPhone for it. If we can’t have Gore, then in every state, in every nation, we need to ask our politicians what they’re going to do about the environment. If they don’t think that it is the number one issue for our times, find someone who does. If they’re not shitting themselves, they’re not paying attention.

Black Rhinos murdered by morons.

This fills me with cold fury. From the BBC:

Efforts to save the black rhino from extinction have been dealt a blow by the killing of three adults who were part of a breeding programme in Zimbabwe.

For the past 20 years the family has been rearing the animals and returning them to the wild, but last week, in the dead of night, armed men in camouflage gear burst onto the site and shot dead all three adult females.

Not surprisingly, the shootings have caused deep alarm among conservation groups, not least because there have been a number of similar attacks in Zimbabwe this year.

One of them was just days away from giving birth. Her unborn calf died as well.

Black rhinos are sometimes shot by poachers, who sell their horns as dagger-handles or for use in Chinese medicine, but the Imire rhinos had recently been de-horned as a precaution, so they didn’t have any value to hunters.

They had no horns. They were worthless to poachers. How could anyone do such a horrible thing? They say it has to do with Zimbabwe’s land crisis, but Zimbabwe makes a great deal of what foreign money it does get from tourists who want to see the big African animals in the wild.

If this bothers you as much as it has bothered me, you can adopt a Black Rhino over at the WWF.
Would make a great christmas present for an animal-loving child, if you’re stuck for ideas.

Whale. It’s what’s for dinner.

As you know, Japan’s whaling fleet has put to sea with plans to kill up to a thousand whales, including for the first time in years, the endangered Humpback Whale. For “Science”. Japanese scientists must be pretty damn useless if they need that many whale corpses.

Of course, it’s not about science at all. It’s about culture. The god-given right for a people to eat whatever intelligent beings they want. But the thing is, whale meat is, well, an acquired taste. Very few people in Japan much like it, so in order for the Japanese government to be able to demonstrate a demand, they’re creating it themselves out of whole cloth.

From 2005:

Schoolchildren in the western coastal district of Wakayama are now being offered an unusual addition to their lunch menus. Whale.

The Wakayama education board is supplying whale meat to around 280 schools, to try to promote awareness of the region’s whaling traditions.

For all of Japan’s success in winning support from other countries for its campaign to ease the restrictions on whaling – especially smaller countries which receive Japanese aid – the Japanese people are losing interest.

Whale meat is only served in a few specialist restaurants, and occasionally appears on supermarket shelves. Younger people almost never eat it.
The official line is that whaling is an integral part of Japanese culture, a practice dating back hundreds of years.

That isn’t quite true. A few coastal communities, like Wakayama, have been hunting whales for centuries, traditionally with hand-held harpoons.

But the rest of Japan only became familiar with eating whale during the 20th Century, as modern ships with harpoon-guns became available.

Whale meat was especially widespread in the difficult years after the Second World War, when it was seen as a cheap source of protein.

But as incomes rose, people switched to imported beef, or fish like tuna and salmon. With such an abundance of high-quality protein available these days, few Japanese see the point in eating whale, which doesn’t taste that special.

They’re forcing whale meat down the throats of their children to recreate the demand that dried up when folks had the option of eating something that tasted better. This isn’t about science. It’s not even about culture any more, really. This is about Japan not wanting to be told what to do.
