In my last post we talked about using images as data. This time we’ll consider another non-traditional source of data: the results of other investigations. Using results to generate more results? That seems weird… at first. But think about how science progresses. We build on other studies all of the time! Sometimes we use others’ findings as a jumping off point. Other times, studies invite us to see if we can reproduce their findings under new conditions or with respect to our own study site or species of interest.Read more
When I think of the ecological data I typically work with, it usually tells me where plants or animals are, how many of them there are, and how those quantities might change. Most often, these organisms boil down to a few spreadsheet cells. But what if the questions you’re asking are less “where is the organism”, and more “what does it look like”?
Photographic data is not a new phenomenon for scientists, but thanks to huge leaps in technology (hello, camera phones) it is a booming data source. Community science – whereby members of the general public submit photos of species they’ve happened across – has seen a huge rise in popularity, thanks to apps and community platforms like iNaturalist. As a result, photo data is constantly growing in abundance, and many studies are quickly adapting to take advantage of this data source.Read more
This question comes from Marney Pratt (@marney_pratt) as she noted that a recent paper tracking trends in ecology papers shows the use of Bayesian statistics increasing over time. (Before we get going, if you want a refresher about what exactly Bayesian thought entails, check out this previous post.) Anderson et al. say:Read more
If we write about our statistical methods behind our ecology work, and none of our readers understand it, have we really communicated at all?
This month I’m getting meta. It’s been about a year and a half since I started writing the Stats Corner for this blog with the goal of demystifying some of the statistical methods that are used by ecologists every day. At the same time, I’ve been writing a book with Deborah Nolan called “Communicating with Data: The Art of Writing for Data Science.” The book was released this spring, so it seemed like a good time to reflect on writing about statistics accessibly.Read more
