New paper: How flowers’ symmetry may affect pollinator diversity

The actinomorphic, or radially symmetric, flowers of a nightshadeA honeybee forages on the zygomorphic, or bilaterally symmetric, flowers of a milkvetch I’m delighted to announce a new paper published today in the Biology Letters, coauthored with Colin Carlson at Georgetown University and a CSUN undergrad researcher, Gio Gomez. In it, we examine...

New paper: Meta-analysis of local adaptation experiments compares sources of natural selection

Low clouds surround mountaintops in the San Gabriel Mountains. The analysis in the new paper suggests that selection by abiotic factors like high-elevation conditions may often be weaker than selection created by interactions between species.

2018 photos: Fieldwork (and tourism) in Spain and France

Gruissan, a coastal village near Narbonne.If I’m really going to take my digital life off Facebook, I have to get serious about tending to a more distributed version of that site’s functions. Exhibit A is my Flickr account, which I’ve gotten lax with updating — I was almost a year behind with uploading images there! The holidays have been a good chance...

#FBexit? Is that a thing?

My #FBexit statement, as posted to That Site.Facebook is a problem. It’s become the only way I’m in contact with a lot of folks, including far-flung family and friends accumulated over a decade of the Academic Nomad life. But it’s also absolutely awful at moderating the news or stopping the spread of falsehoods, and it continues to seek new ways to...

New paper: Conflict and communication in mutualism

*Medicago truncatula*, or barrel clover, a member of the legume family that hosts bacteria in its roots. The bacteria transform nitrogen gas from the atmosphere into fertilizer for their host plant, and the host feeds the bacteria with sugar. Experiments with barrel clover and its mutualists have shown that signals between the plant and the bacteria...

The Yoder Lab opens in fall 2017

I’m very excited to announce that I’ve accepted a faculty position with the Department of Biology at California State University Northridge, starting this coming fall. CSUN is about as close as possible to the ideal place to do the kind of science and scholarship I want to do — a large, diverse public university with strong support for teaching and...

New paper: Understanding mutualism with population genomics

Comparing metrics of diversity (x axis) and geographic differentiation (y axis) for thousands of genes in the Medicago truncatula genome (gray points) reveals that some symbiosis genes (red points, crosses, and triangles) are genome-wide outliers — but they are not all the same kind of outlier. Yoder (2016), Figure 1. My very latest scientific publication...

My review of Lab Girl for the LA Review of Books

How should I illustrate a review of Lab Girl? Let’s go with a cool plant. This is bunchberry, Cornus canadensis. (Flickr: jbyoder) You have surely, by now, heard all about Hope Jahren’s terrific scientific memoir Lab Girl, including as one of my “bookshelf” recommendations for Chronicle Vitae. My full-length review of Lab Girl is now online at the...

A new Queer in STEM starts soon!

There’s big news today at the Queer in STEM project site: we’re about to launch a new iteration of our online survey. Queer in STEM 2.0 is happening thanks to Joey Nelson, a PhD candidate in geosciences at Stanford, who approached us last fall about developing a new study to build on what we’ve learned from the first Queer in STEM survey. He had some...
