I never tire of the landfill

Today was the fourth collecting trip to the Pope-Douglas County landfill. What a beautiful day for collecting! And what diversity! There were many new plants I had not seen, some that have yet to begin flowering. I lament not being able to stay longer and collect more. I’m sure I could add 50 more species. I’ll definitely be back next year and start earlier to get a full species list for the site. For those of you who have missed out on seeing some of the fascinating plants out there, pictures from today’s collecting trip, courtesy of Christine, will be forthcoming. As for the collections (including a nettle that still has my thumb stinging), I made 27 collections, including big bluestem, side-oats gramma, dahlia, onion, honeysuckle, sage, ragweed, goat’s beard, milkweed, sweet clover, golden alexander, and goldenrod. Who knew I’d ever make visiting a landfill a habit?

Lani and Denise’s posters

Hey team Echinacea,
Lani and Denise officially finished their REU internships last Friday and are both back in the California bay area. They both worked really hard on their projects and ended up with some really neat studies. At the end of their internship they created and presented a poster for a research symposium. Their posters turned out really well and I wanted to share them with you. Below are links to each of their posters…enjoy!

Echinacea baking

This summer, a very large portion of our lives has been devoted to that Purple Coneflower, Echinacea. This plant has infused itself into our conversations, dreams, birthday cards (my little sister has one coming with a bee and a purple flower,) and yes, baking.

Can you guess what these are?

Seedling cupcakes with vegan chocolate earth, marzipan greens, and sprinkles for the pubescence. Megan’s idea.

What about this?

Why, that is an Echinacea leaf chocolate chip cookie, of course.

Even if we cannot eat the Echinacea, at least it inspires us to bake delicious desserts :).

late in ’08 — phenology status

Echinacea angustifolia is flowering late this year.

Peak flowering this year was 27 July. Peak was 12 July and 14 July in 2005 and 2006 respectively. Here’s a rough graph that shows flowering phenology in these years. Red dots are the count of fl plants on each day. Horizontal gray lines indicate days that each plant shed pollen.

See the updated animation of flowering in the common garden experimental plot.

This animated GIF file is a map of all plants that flowered in the CG on each day from July 5 to July 30th. Each dot represents a plants that’s flowering on the day (see upper right corner).

Virgin Mary Vegetables

Here is a picture of the “inside-out cucumber” that Per brought into the Hjelm house today. But is it merely a strange vegetable or an apparition of the Virgin Mary? The vegetable says you must make a pilgrimage so that it can give you blessings.

Speaking of killing and bees

While perusing the BBC Mundo website to improve my Spanish, I ran across an article explaining the relation between tracking bees and tracking serial killers. And apparently, these British scientists are using tiny, tiny radio transmitters to track their bumblebees. An article just about the scientists from February was linked to on the page, and that article even has a video on how they attach the transmitters! Again, no ice packs, but no dominant hand and forefinger, either. Using forceps, it looks like they have the bee put in a special container that presses the bee against a mesh with foam, and then place the tag. Pretty cool, but I think a Melissodes is a little to jumpy for that, compared to a quiet bumblebee. Food for thought, though, I suppose. Thanks, BBC!

Bee Killers on the Loose

Robberflies can catch bees in midair. I’ve never seen it myself but I know that’s not all they can do….

New Evidence Implicates Spider in Bee Disappearances

The spider could not be reached for comment.

Could it be?

There’s something going on with the grasses in the common garden. I’m not sure whether it’s crown rust, but it might be.

Bee Team, way better than the A Team

Hey everyone,

We’ve been working at organizing and analyzing our data and just wanted to share some of the highlights with all of you and give some tips for next year’s bee squad.

– 9 bee genera recorded
– 72 bees painted
– 258 bees recorded
– 330 flights recorded
– 831 head visits recorded

We’ll post some nice flight maps once we have them put together (Denise is quickly becoming an R expert).

And now some advice for next year…

– For us, it worked well to set 15 minute observation/catching time blocks and to then check on all of the bees in the cooler after those 15 minutes. That way we weren’t trying to catch and track new bees while also trying to paint and track our already caught bees.
– We liked standing two ice packs up in the cooler with the glass vials standing up in between them. This made it easy to see the labeled lids and also preventing the bees from crawling into the lid where it took them much longer to cool down. But be sure to check on the bees frequently because they get colder much faster this way than if the vials were just lying underneath an icepack.
– We placed the bees on a Petri dish to paint them, which gave us a sturdy base for holding them. And of course made use of last year’s paint holsters (made from duct tape and eppendorf tubes) and painting tools (bent section of wire from a flag, sanded and attached by duct tape to a stick as a handle).
– We opted for paper forms over visors, which we liked, but there needs to be a better way to keep track of several bees at once. Having 2 recorders made a huge difference when the bees were active and we had enough people. We could get by with just 2 people on windy/rainy/generally mellow days, but having more was helpful. We’d recommend 2 recorders and at least 4 observers on busy days.
– Somehow none of us had a watch and had to rely on Denise’s cell phone. A watch might be more convenient…
– For the first day or two, it might be a good idea to take the bees back to the Hjelm house and ID them with the bee box.
– Silver and lavender look very similar once they’re on a bee, and it can be hard to tell between silver and white on a bee that was painted a few days before. Likewise, aqua, light blue, and green can be easily confused.

The bees we saw this year were:
– Ceratina calcarata (tiny, black, vertical white line on face)
– Pterosaurus albitarsis, sadly renamed something much less cool (light yellow “W��? shape on face)
– Agapostemon virescens (metallic green head with striped thorax and abdomen)
– Augochlorella striata (whole body is metallic green, but a much smaller bee)
– Melissodes (we saw a few different species, two of which aren’t in the bee box)
– Megachile (the best way to describe their front legs is burly. If I remember correctly, these guys are pretty hairy too)
– Halictus rubicundus (looking at the bee box will give you a more detailed description than I can)
– Dialictus (many different species of tiny black bees. Too small to paint or ID in the field)
– Apis mellifera (Honey bees! The first time Stuart has ever seen a living one on an Echinacea head. They cool down much faster than the other bees, so be careful with them. Also, we got the sense that they mostly hung out on alfalfa and rarely on Echinacea, so that could be an interesting thing to look into)

That’s all for now. We hope you guys are having a great time and getting a lot of measuring done. Stuart, if you have a chance we’d love to get those photos you took on the 17th so we can try to match them up to specific flights. And Megan, thanks for the homemade candy bars!
