Pond scum with a vengeance.

Blue-Green Algae Close 98 Quebec Lakes … More Closures as Cyanobacteria Problem Worsens … Ancient Bacteria Plagues Quebec … Town Councils Make Clouseau Look Like Maigret

Well, I made the last headline up, but the others pretty much tell the story. As it turns out, the on-again/off-again cyanobacteria infestation I posted about earlier in not only a Lac Mercier phenomenon. While we’ve suffered two more beach closures since my first post, other lakes have fared worse.

Blame is being placed everywhere dishwasher detergent; leaking septic systems; agriculture runoff; global warming. To me, lawns are the obvious culprit. Development has been very aggressive the last few years, with whole new subdivisions going in. The lawns that come with the houses are a double whammy; forest (which takes nitrogen and phosphorous from the soil) is uprooted, and sod is put down and way over-fertilized. Landscaping has been banned within 15 meters of shore, but continues unabated for the hundreds of other meters between shore and mountain ridge.

The Quebec Legislature wants to ban phosphates in detergent; I haven’t seen a proposal to ban lawn fertilizer.

Mice

Back in early June, I spent half an hour stalking this guy, before chasing him into the mudroom. There, he found an empty bottle of mead, lapped the neck until drunk, and let himself be tossed outside. That was pretty much it with mice for the summer. And then, last week, I killed 12 of them in the house. I needed more traps, but 5 Mont Tremblant stores were sold out. Local exterminator said that he’s been killingmice for 23 years, and that he’s never had this many calls.

All of last week’s victims looked pretty much like the good natured inebriate from the spring. Deer mice (Peromyscus maniculatus), says my lazy man’s guide to mouse identification.

Back home in Toronto, we also have an infestation, thanks to our psychotic summer tenants who spent a month throwing garbage in the garage and leaving it there. But these are darker, and more uniformly colored. I suspect Mus musculus, and will post a picture if I come across one slow enough to pose.

Here are some things I’ve learned:

  • Mice breed like rabbits. Sexual maturity at 2 months; 3-7 pups per litter; 4-10 litters a year.
  • 9 millimeters is all they need, as they collapse their rib cage and perform other skeletal tricks to get through holes.
  • Hantavirus (borne by deer mice) is here in Ontario and Quebec.
  • Wikipedia claims they are eaten as a delicacy throughout eastern Zambia and northern Malawi.

    For your reading pleasure, I’ve put an acronym- and technology-heavy post about the Taxonomic Databases Working Group meeting up at the Semantic Naturalist.

    white butt bumblebeelady beetle
    I wasn’t able to do too much FieldMarking during my recent Slovakia trip, but I did catch a few of these white-tailed bumblebees (Bombus certainly, probably lucorum or a close relative) feeding on thistle nectar. Also a lady beetle (probably Coccinella septempunctata).


    magpie in flight
    I’m always happy to see corvids, magpies (Pica pica, Pica, this is for you) and carrion and hooded crows (two forms of the same species, Corvus corone). A blue tit, something finchy, a raptor that was probably a kestrel, lots of pigeons, and I heard house sparrows. Surprisingly, no starlings, and no squirrels.

    Announcing Spotter 1.0

    On Friday we announced the release of our semantic blogging tool, Spotter. There are more details on our parent blog, eBiquity. This is the tool we’ve been using to add the little owl that links to RDF-formatted observation data on this blog. As long as you are using Firefox, you should be able to use it on any blog or any other web page where you can add links.

    Please consider using Spotter and letting us know what you think. This is ongoing research and we need feedback to help improve our work.

    Introducing The Semantic Naturalist

    Semantic Naturalist logo -- dewy spider web
    Our Spire colleague Allan Hollander of UC Davis’ Information Center for the Environment has launched a group blog, The Semantic Naturalist. Joel and I will join Allan there in tracking semantic technology developments related to biodiversity, so if that’s your interest, hope to see you there. We’ll keep this blog for actual observations or general biodiversity informatics news.

    In related news, as Tim Finin notes, Peter Wayner’s article in yesterday’s New York Times featured our work. I’ll let others critique the article, but will say that it is nice to be cited as a concrete example of semantic web technology. We may not yet be reaping great rewards but we are making an effort to use real world data as openly as possible.

    So far we’ve seen only a modest bump in traffic here on FieldMarking. Welcome, if you’ve found us through the NYT article.

    Medium-sized city-bird day

    Filed under: behavior, crow nuisance, observation, phenology — cyndy @ 8:18 pm

    Yesterday I spent the afternoon down in DC. Though most of my time was spend indoors at the National Museum of National History (if you have to be inside, not a bad place!), I did spot some interesting birds.

    First, I saw two different rock doves (Columba livia, aka pigeons) that were color banded. One was /R Bl (that would be red over blue on left) and the other I believe was /Bk R (that would be black over red). I’m afraid I didn’t jot them down, but I can say that the red bands are correct. Wonder who is banding them and what they are learning.

    Second, around dinner time a steady stream of American crows (Corvus brachyrhynchos) was heading over the Potomac into Maryland. My guess is they were coming in to a large roost from the nearest agricultural area in Virginia. In fact, they looked headed roughly for Rockville, which I know has been home to a large roost. But could there be one closer? Factoid: American Crows typically don’t gather in large roosts during the breeding season, but in Fall and Winter some roosts can include on the order of a hundred thousand birds.

    Latest Encyclopedia of Life press

    Filed under: biodiversity informatics, technology — cyndy @ 9:26 pm

    The New York Times published an Op-ed piece by E.O. Wilson today.

    … a new project in biology, an ambitious effort to create a vast new electronic database of known species, should make it possible to discover the remaining 90 percent of species in far less than 250 years, perhaps only one-tenth that time, a single human generation. On May 9 of this year, a consortium of institutions from Harvard and the Smithsonian to The Atlas of Living Australia began compiling The Encyclopedia of Life, which one day will provide single-portal access to all knowledge of living organisms.

    Simultaneously, an interview with David “Paddy” Patterson was published in the journal Nature:

    In February next year, hopefully, there will be a major release of the first
    edition of the EOL. The expectation is that within a ten-year period we will
    have relatively well-informed pages on all 1.8 million species.
    . . .
    Some of the features we’re developing will be rather like wikis or the
    social networking software out there. One of the things I would love to see
    develop early on is a ‘my schoolyard’ function in which kids can go outside
    with cell phones and take pictures of organisms and submit them to the EOL.
    There, the pictures are sent off to experts who verify identification. And
    when that is done, a little dot appears on Google Earth showing the presence
    of, say, a daffodil in someone’s backyard.

    My listservs, ecoblogs, and ADW staff emails are buzzing.

    Some of my colleagues have been skeptical. We’ve heard these grand plans before, weren’t consulted about the technical details, and had no idea if there were opportunities for us. Donat Agosti plainly states that it is “a secretive project.” As I mentioned in a previous post, this “new” project rests on the backs of many of us who have been toiling, underfunded, for years to get information online and easily available to the public.

    This latest PR seems to me an offensive in pursuit of more funding — but for whom? Even if EOL wants to keep the organizing membership elite (Harvard, Smithsonian, etc.), I’d urge the EOL organizers to reach out more to the community whose research should be informing their efforts. For example, parts of the My Schoolyard concept have already been tested by the BioKIDS project. And of course Spire is working on an even more Web 2.0 approach with our semantic Spotter tools.

    I’ve been told that TDWG (Taxonomic Databases Working Group) standards are going to be followed. But there’s quite a lot of flux now. Will taxon names get marked up with TaxonX or TaXMLit? With the species microformat? I’ve also heard that there is a semantic web component planned — but haven’t seen the plan for how to mesh with existing efforts like ours (ETHAN, etc.) and the nascent Biological Observation standard. Others, such as David Shorthouse, have provided helpful suggestions.

    Personally, I am less concerned about which standards and technologies are chosen as long as there is some sensible web service allowing the exchange of information. I am even willing to concede that semantics-lite approaches may mostly work. It is more important to me that we can support each other in building high-quality, user-friendly sites. I say sites because there will always be a role for special-purpose sites. Wikipedia is great but it hasn’t put everyone else on the web out of business. A portal like EOL won’t either.
