Firstly, [livejournal.com profile] cottonmanifesto took this picture. I saw and and was delighted, went to the compost heap myself and shot about a dozen pictures. Finally after disgusting myself with my collection of substandard photos, I decided to ask permission to use this one.

Cap and stem mushrooms aren't common in the New England springtime. It's only the heat of decomposition and the quick life-cycle of this fungus that allow these to thrive now. Many mushroom species emerge from a fungal mycelium that has been growing for months or even years. Coprinoid mushrooms are different, coming from a mycelium that grows quickly through an ephemeral food supply--dung, wet straw, compost, etc.

These are most likely Coprinopsis, one of the genera that was split from the formerly monolithic and easy-to-study Coprinus mushrooms. The mushrooms in these groups turn into a inky mush in order to spread their spores. Despite having that in common, several of these groups turned out not to be closely related to one another, requiring the shuffling of taxonomic names and the coining of the word "coprinoid" to refer to them all.

The scurfy scales on the tops of these mushrooms tempt me to identify them as Coprinopsis lagopus, the rabbit's foot inky. However that would be rash--microscopic examination of the spores would be a better way to try to speciate these.

Chinese mantid Tenodera aridifolia sinensis

This mantid perches on a jar of fruit flies provided as easy prey. It and its many brothers and sisters hatched from an ootheca produced by this large female. Chinese mantids are becoming the most common mantids in North America, due to deliberate releases to control garden pests. I heard of more folks encountering mantids this year than any time since I was a child.

Mantises used to be lumped in the same Order as cockroaches and termites, and the information on Bugguide.net makes it sound like they still should be: "The concept of an order that includes at least cockroaches, termites, and mantids is nowadays widely supported by scientists." Furthermore, mantids "can be reasonably described as predatory roaches."

That last part doesn't quite pass the sniff test for me--the elongated thorax, the mobile head, the raptorial forearms...Even if it is correct taxonomically, it's a violation of the language: calling a mantid a predatory roach robs both words of their meaning.

My Canon camera (the one I bought to replace the one I dropped in the Muddy River) no longer works. The motor won't extend the lens when I turn it on. I don't seem to have the data cable to my other camera, a Pentax digital SLR. I ordered a new one, and it should be here this week. No photos alas until that's resolved. But some other interesting stuff is going on:

I found a great piece of science journalism. This story combines several passions of mine: lifeforms that are preadapted to live in man-made ecosystems, booze, and taxonomy. The story doesn't resort to idiotic puns or name-checking pop culture either. Go read. "Evolution is full of stories of animals and plants fitting into hyper-specific man-made niches, as if nature somehow got the specs in advance."

A strange thing happened on Saturday, and Alexis wrote a letter to the town administrator about it:
here it is )

I'm scheduled to do a bunch of interesting things in the next few weeks: Present a slideshow to the Friends of the Muddy River, participate in a BioBlitz, host a housewarming party (in the area and weren't invited? email me your email address/facebook name), go on vacation with my brother and father, then help run some fundraisers.

Mostly I'm excited because we're having a fence built.

Also, this lives in my house now.

Yesterday's zebra post, all of three sentences, took way too much effort. I got stuck on wanting to refer to the Grevy's zebra as the largest horse. I knew that if I did that, it would cause some discomfort among certain of my readers. But all living equids (ugh, that's so unsatisfying) are not only in the same Family (the way that foxes and dholes are in the dog Family) but they are in the same Genus (the way that wolves and coyotes are in the same genus as domestic dogs). So donkeys, domestic horses, wild asses, and zebras are all in Genus Equus, and there should be a single word to refer to them--and there is, it's Equid. No one gets upset when you refer to lions and jaguars and pumas and snow leopards as "cats."

It's complicated, and it has to do with the great closeness humans feel for domestic horses. They are to be elevated above all others in their Genus, the lowly asses and burros. And just look at the brouhaha that ensues when you suggest that they are as edible as cows.

There's also the complication of taxonomic correctness, the itchy brows that people get when you call a beetle a "bug" or a gorilla a "monkey." There's really no danger in calling a non-hemipteran a "bug" or calling a great ape a "monkey." (The animals that are "correctly" called monkeys are in two widely divergent groups that really have no business sharing a name. Why should a marmoset and a mandrill get the same common name and not share it with a siamang or a sifaka?) Calling a whale a "fish" is more egregious, as it betrays an ignorance of the animal's essence, and serves to unjustly distance the creature from its kinship to us.

I reserve the right to call a fox a "dog," an ocelot a "cat," and a zebra a "horse." To resist is to succumb to arbitrary convention, my least favorite convention.
