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.

September

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!

Greenhouse update

Fish are happily enjoying the summer, too. The plants in some of the tanks are blooming, and we have visitors!

More travel in August….

The lab is scattered: Trai is still in Europe, Ingo just got back, and Rodet is in DC to study Limia specimens. Former lab member Elizabeth just had a paper from her Masters Thesis accepted in Ethology! Hurray!

Summer is here

July is a month for travel, conferences, adventures. Trai and Ingo presented their research at the Behaviour 2017 Conference in Estoril, Portugal. It was a great conference and we both learned a lot. 

Trouble in paradise

One thing I noticed during a recent visit to Jamaica is that invasive species are found in many places and in large numbers. This Xiphophorus maculatus is just one example.

 

May is here….

Only days until the Poeciliid meeting!

At the SWAN Meeting in Lawton, OK

The lab had good representation at the SWAN conference: Rodet gave a talk, and Trai and Ingo had posters.
