Viva la Neo-Fisherian Liberation Front!
by jebyrnes in I'm a chordata, urochordata!
p≤0.05
Significant p-values. For so many scientists using statistics, this is your lord. Your master. Heck, it has its own facebook group filed under religious affiliations (ok, so, maybe I created that.) And it is a concept to whose slavish devotion we may have sacrificed a good bit of forward progress [...]... Read more »

The Conservation Horizon
by jebyrnes in I'm a chordata, urochordata!
Every so often, a conservation problem rears its head that, upon reflection, we realize we had some inkling of even decades ago. Global warming, biofuels, overfishing, etc. The information was there, but scarce, buried in obscurity, or seemingly counterintuitive. Why not try and recognize the crucial questions early, before the lobster is [...]... Read more »

Sea Stars on Acid
by jebyrnes in I'm a chordata, urochordata!
As an ecologist working in temperate climes, I’ve been following the ocean acidification field with some interest. It’s always been obvious to me how acidification has enormous ramifications for coral reefs and other tropical marine ecosystems. They exist in warm waters already, often close to their thermal maxima. Acidifying the water [...]... Read more »

Lytechinus: Pack Wolf of the Sea
by jebyrnes in I'm a chordata, urochordata!
So, you know, I’m cruising along, trying to determine the diet of the white urchin, Lytechinus anamesus, from the literature. There’s your usual “It eats kelp” papers, a few red algae papers, and nothing else special and then - A PAPER ON LYTICHINUS EATING OTHER SPECIES OF URCHINS.
That’s right, baby, urchin on urchin predation. [...]... Read more »

Mapping the Sasquatch
by jebyrnes in I'm a chordata, urochordata!
I love modeling! I love modeling! Modeling will solve everything!
Let’s model the spatial distribution of Bigfoot!
WAIT, WHAT?!
Figure 1 from the paper. Foots denote sighting of Sasquatch footprints. Circles for just visual/auditory sightings. I ask, how does one know what Bigfoot sounds like?
Yes, it sounds silly, but in the current issue [...]... Read more »

New Ideas in Ecology and Reviewing
by jebyrnes in I'm a chordata, urochordata!
Recently on ecolog-l, there has been a thread going around about journal publishing - open access v. pay-for access, impact factor, elitism, reviewing, etc. The central question seems to be, is the publication system somehow broken? Do we need to fix it? Is the model of journals such as PLoS Biology or [...]... Read more »

snails going nom nom nom = productive diverse tidepools?
by jebyrnes in I'm a chordata, urochordata!
The “gold standard” experimental design for asking how do changes in biodiversity change ecosystem function has been to randomly assemble communities of varying species richness, but equal abundance, and examining differences in function from one level of richness to the next.
But let’s be honest. Changes in diversity due to impacts by man will not [...]... Read more »

when NOT to MANOVA
by jebyrnes in I'm a chordata, urochordata!
And now its time for a multivariate stats geek out.
The statistics that we use determine the inferences we draw from our data. The more statistical tools you learn to use, the more likely you are likely to slip on a loose bit of data, and stab yourself in the eyeball with your swiss-army-knife of [...]... Read more »

the light! the heat! the feedback!
by jebyrnes in I'm a chordata, urochordata!
Sometimes, the devil IS in the details. I’ve been thinking about feedbacks between community community structure and function lately, and run into a few curious roadblocks, as well as one very very interesting story.
First, the roadblocks. Just what do we mean by structure and function, particularly in reference to a [...]... Read more »

Algae fight on the side of light. Inverts, not so much...
by jebyrnes in I'm a chordata, urochordata!
So, given my recent transition, it gives me great pleasure to talk about a paper that kind of sums up both halves of my split personality these days. Inverts and algae - who will win! The recent Miller and Etter paper in Ecology I think is not only a great piece of experimental ecology - careful, painstaking, and thorough - but it's also just a nice piece of natural history looking at the New England subtidal.
Oh, and maybe I worked on this project as an undergrad tech, and, well, maybe ........ Read more »

The Dim Sum Principle: Resource Complementarity Increases in Importance with Density
by jebyrnes in I'm a chordata, urochordata!
In order to have a fun time at Dim Sum, you need a lot of people so that there's lots of plates to try from. But, if you went, and everyone wanted Char sio bau (Pork Buns), how boring would that be? And how many fights might break out over that last little bun?
This is the kind of science I think about - only, in the ocean.
And for this reason, I just about plotzed with joy when I saw the opening paper by Griffin et al in this month's issue of Ecology. The paper, Predator diversit........ Read more »
