Week 15 Recap: 8709 person-minutes and counting

Week 15 went well – the GGI is getting very fast out there. We did a survey of the participants on Friday, and it looks like things are going well:

That’s good, and it probably means we’ve gotten past the steepest part of the learning curve. Here’s more data to indicate that folks are feeling pretty confident with data collection and the protocol. I’m that most of you feel comfortable asking questions if you aren’t sure about something – if you aren’t sure, please ask.

Also good news is that most folks recognize that they are contributing to a real research project, and learning something along the way.

These trends match what I’m seeing in the data – fewer errors, and very high data quality – nice work everyone! Check out the latest tables:

Looks like Week 15 is pretty similar to Week 14 in terms of milkweed status, though the plants continue to grow, and there might be a trend towards more larvae week by week.

Kinda surprisingly, it looks like we are seeing more larvae in the southern part of the transect. They used to be mostly near the western end of Mockingbird, but now you can see some more activity down south of #400. I wonder if the monarchs are favoring these plants because they are smaller and less defended? The plants from #199-399 do tend to be larger.

I did have a chance to visit a couple of other field sites this past week. I took a timelapse photo of a milkweed at the Hastings Reserve (part of the UC Natural Reserve System).

I also took some students in my lab out to Bobcat Ranch, owned by California Audubon. Do you recognized any of these characters?

I also read an interesting news article about the decline of western monarchs. It seems like a pretty big population decline. What do you think?

Finally, I found an image to convey some of our previous discussion of accuracy and precision:
