Job Opening. Faculty Position in Plant Evolutionary Biology at University of California, Davis in the Department of Evolution and Ecology (EVE, my home department). More detail here. recruit.ucdavis.edu/JPF07777
POSITION DESCRIPTION

The College of Biological Sciences at the University of California, Davis invites applications and nominations for a 9-month, tenure-track position in the Department of Evolution and Ecology at the ASSISTANT PROFESSOR level. The Department of Evolution and Ecology is seeking a plant evolutionary biologist with interests in the evolution of plants at any taxonomic, geographic, organizational, or evolutionary scale. Candidates must have a Ph.D. (or equivalent) in the biological sciences, evolutionary biology, ecology, genetics, or a related field, and will be expected to complement and build upon existing faculty strengths in the Department of Evolution and Ecology and across UC Davis.

We welcome applicants working on any group of plants and using empirical, computational, experimental, and/or theoretical approaches. Possible areas of study are broad, and include macroevolutionary research on plant diversification, trait evolution in a phylogenetic context, major evolutionary innovations, comparative genomics, and evolutionary developmental biology, as well as research focusing at or below the species level including population biology, quantitative genetics, adaptive evolution, speciation, biogeography, and the evolution of life histories or species interactions.

In panel 3, there are some terrifying red and flesh colored plants with toothy maws and the text says "Hydnora are leafless, bizarrely fleshy, and incapable of producing chlorophyl..." and in panel 4 there are some cute hearts and the text says "And so are you.

These papers gave a framework to analyze spatiotemporal variation and a reason to test for ecological relationships. I wasn't expecting anything but I figured what's the worse that could happen? Another null result? I'd been down that road with these data before.

This paper was also an inspiration onlinelibrary.wiley.com/doi/abs/10.1... At first I regretted not counting those stigmas I collected for pollen grains and other forms of the ecology of the populations. But we did have seed predation and abortion rates.

What if I had chosen the wrong traits? Maybe I needed more statistical power...I should have observed more interactions...but I kept thinking it should be published at the very least since we had multiple populations over multiple years of data.

Amy Parachnowitsch @evoecoamy.bsky.social · 05/12/2025
This brings me to the challenges of writing papers with essentially a null or negative result. It wasn't just that it is tough to convince others but it can also be hard to convince yourself. I did work on the data over the years and write a few drafts but it never quite got there.

Amy Parachnowitsch @evoecoamy.bsky.social · 05/12/2025
I was sure we'd finally be able to see some differences in selection that could be attributed to a cause. But no! Flowers were starting much earlier but selection on the traits was really just similarly variable. Another interesting and important story I thought but difficult to write

Detail of the water pot decoration. Grasshoppers carrying flowers are also accompanying a palanquin, used to carry... presumably high ranking lady grasshoppers. A couple might also be katydids based on antennae length, but let's not get uptight about imaginary anthropomorphized bugs, eh?The little freshwater pot, with a wooden top. This side shows more grasshoppers (possibly a katydid) carrying fruit and flowers as they march along on their hind legs.
