Almost Thanksgiving

It is hard to believe, but November is already almost over. We have been very busy with manuscripts and teaching. Trai and Ingo will both attend the ASAB Winter meeting with presentations in early December in London. And we are planing for the upcoming field season!

Almost November…

Wow, time flies. We were all super-busy with papers and proposals. Trai has submitted to NSF, Rodet to the Whitley Foundation, and Ingo submitted a long review to Current Zoology. Now we need to hope for good news!

New paper out in Ethology

Elizabeth’s paper on swordtails is now available online here. This was the centerpiece of her Masters Degree work, and also a great collaborative effort with Lloyd Bumm from our Physics Department.


The outdoor season for the fishes in winding down. We are in the process of moving them to their stock tanks inside the Greenhouse. Winters in Norman are not warm enough to keep fishes outside.

Color changing Swordtails

Green swordtails (Xiphophorus hellerii) have colorful lateral stripes. In one population from Actopan in Veracruz, we detected that they can actually change the color of the lateral stripe. Dominant males sport a red stripe, whereas subdominant males show a brownish, black stripe. They can change color within a few seconds to minutes. This was first discovered by Sam Rhodes and a follow up study by Elizabeth Hardy is about to be published in Ethology. Click on Color Changing Swordtail to see a short movie filmed by Sam Rhodes.

Rodet visits the Smithsonian

Just before the semester starts again, Rodet spent a few days examining specimens of Limia from the Dominican Republic. Many of the type specimens are in the fish collection of the Smithsonian and can only examined on site. Thanks to Lynne Parenti for hosting Rodet!
