Random thoughts on ecology, biodiversity, and science in general. Piecewise structural equation modeling in ecological research. July 6, 2014. March 10, 2016. Nature is complex. This seems like an obvious statement, but too often we reduce it to straightforward models. And that sort of thing. Not that there’s anything wrong with that: sometimes.

Random thoughts on ecology, biodiversity, and science in general. How much is enough? A new technique for quantifying precision of community surveys. March 31, 2015. April 7, 2015. I’m always looking for ways to improve my balance, which is why I was interested to see a new paper in. Called “Measures of precision for dissimilarity-based multivariate analysis of ecological communities”. By Marti Anderson and Julia Santana-Garcon. 8212; comes in. It solves the common problem of, as they state:. In other wo...

Random thoughts on ecology, biodiversity, and science in general. Using parallel processing in R. June 13, 2013. June 30, 2013. Lately I’ve been running a lot of complex models with huge datasets, which is grinding my computer to a halt for hours. Streamlining code can only go so far, but R is limited because the default session runs on only 1 core. In a time when computers have at least 2 cores, if not more, why not take advantage of that extra computing power? Heck, even my phone has 2 cores.*).

Random thoughts on ecology, biodiversity, and science in general. Collaboration: a problem shared. July 6, 2013. October 15, 2013. I wanted to quickly highlight an article by Cameron Walker titled “Collaboration: A problem shared”. That appeared in Nature Jobs this week. It highlights some of my research done as part of the Dimensions of Biodiversity Distributed Graduate Seminar. I’ve wrote about collaboration before, specifically this program. So I was happy to see it get the press it deserves!

Random thoughts on ecology, biodiversity, and science in general. Marine biodiversity and ecosystem functioning: what’s new and what’s next. November 14, 2014. This is a cross-post with the Oikos blog. Promoting our new synthesis on marine biodiversity and ecosystem function research. Check out the open-access PDF here. I mean, really. There have been several meta-analyses published in recent years. Do we really need this work? Well, our answer to the question is yes. Here’s why. Focused solely on how ri...

Random thoughts on ecology, biodiversity, and science in general. What is functional diversity, and why do we care? October 20, 2014. This post is written to highlight a recent experiment which is now hosted as a preprint in. You can find that paper here. Check it out and provide some open peer review! Here’s an example. Consider two rocky shore communities, 1 (left) and 2 (right):. The gooseneck barnacle (. The thatched barnacle (. And the acorn barnacle (. As well as the mussel (. And a seagrass (.

Random thoughts on ecology, biodiversity, and science in general. I’m a post-doctoral researcher studying marine ecology at the Virginia Institute of Marine Science. The College of William and Mary in Gloucester Point, VA. My interests span from community ecology, with a focus on seagrasses, to biodiversity science to ecological statistics. My post-doctoral work involves understanding the patterns and drivers of submerged aquatic vegetation in the Chesapeake Bay over the past 30 years. Describing large-s...
