organized by Molly Cummings and Caitlin Gabor

Dear Friends, Colleagues and Fishy Folks,  

We wanted to send out a Save-the-Date email to invite ‘all y’all’ to join us for the 11th International Conference of Poeciliid Biologists. The meeting will be held from 8-10 October 2024 at the University of Texas at Austin and Texas State University— San Marcos (USA). 

While we are still working on the program, we wanted to let y’all know that the meeting will continue to address all aspects of Poeciliid biology— from genomics, neurobiology, hormones, behavior to ecosystem ecology. Importantly, we welcome contributions on all livebearing families (e.g., Anablepidae, Goodeidae, Zenarchopteridae).  

Exciting news is that this will be the first Poeciliid Biologists Conference that will be a partially joint meeting with the “Aquatic Models for Human Disease” Conference  The first day will overlap with the AQMHD conference (Oct. 8th) in San Marcos.  Transportation between Austin and San Marcos will beprovided.  

Important dates:  

We’ll send out a Link to our ‘growing’ website: January 15 th, 2024

Abstract submission deadline: May 20th, 2024
Selection of talks and poster presentations: June 20th, 2024
Registration deadline: July 1st, 2024

**Note: our conference dates are sandwiched between the two ACL music festival weekends, so booking travel early will be important (

We offer the choice between oral or poster presentations.  We invite anyone to submit a talk, including undergraduate students, starting graduate students, as well as junior and senior PIs. 

We would appreciate it if you could share this announcement with your professional network, and please have them email Caitlin so we can update our list. We look forward to seeing many of you in Texas! If you have any questions, please don’t hesitate to contact us.  

Warm wishes from Texas,  

Molly Cummings & Caitlin Gabor
