Kryptolebias marmoratus lineages in Genome

Our paper describing the resequencing and comparison of 15 different mangrove rivulus Kryptolebias marmoratus lineages. The rivulus is preferentially self-fertilizing and yet we  found a remarkable amount of genetic diversity across the species even in lineages that have been selfing in the lab for over 10 generations. Here’s some press about the article.

Leatherback turtle publication by Luana Lins

A paper Luana co-author was recently published in the Journal of the Marine Biological Association of the United Kingdom titled: “Revisiting the genetic diversity and population structure of the critically endangered leatherback turtles in the South-west Atlantic Ocean: insights for species conservation” Congratulations Luana!

The worldwide population of the leatherback sea turtle is listed as critically endangered by the IUCN Red List. The study found that the Brazilian rookery has individuals from different areas in the world including turtles form the West Atlantic, despite recording low nest numbers per year. This study provides a baseline to understand population dynamics in the Atlantic, and to build comprehensive population assessments to support and develop management strategies. Additionally, this study highlights the importance of Brazilian in the conservation of the leatherback sea turtle. Brazil has both the only known regular rookery in the South-west Atlantic, and a mixed-origin foraging area for the species along its coast.

Luana is going to Antarctica!

We are all very excited that Luana Lins, a postdoctoral researcher in our lab, has been selected to be part the NSF Advanced Training Program in Antarctica for Early Career Scientists (https://www.usfca.edu/arts-sciences/antarctic-biology-training-program).

She will spend a month in Antarctica as part of the program where researchers will get involved in research projects and will be more knowledgeable of the logistics of conducting studies in this unique environment. Luana Lins is following on the footsteps of our PI Joanna Kelley who participated in the same program in 2008, and her PI Willie Swanson who participated several years before that.

Our lab is very interested in adaptations to extreme environments and Luana is working in a project focused on the adaptations of fish to polar environments, Luana’s training will be great to the development of our polar adaptations project. She will be posting about her preparations and experiences in Antarctica at her blog (https://www.drluanalins.com/blog).

Scott Hotaling joins the lab

Scott Hotaling has arrived in Pullman! We are very happy Scott has decided to join the lab as a postdoctoral researcher. He has already started wading through the vast amounts of data we have been hoarding in the lab and making great progress!

Poeciliid 2017

Just returned from Poeciliid 2017 in Norman, OK. It was a fantastic meeting! The organizers Ingo Schlupp and Edie Marsh-Matthews did a fantastic job planning the meeting. The meeting was small and intimate, with only one session at a time, which was the perfect opportunity to connect with other poeciliid biologists. The topics were varied and ranged from genomics to behavior to phylogenetics to nutrient transfer. The participants ranged from new graduate students to senior faculty members, which made for a great mix of experiences, ideas and knowledge. There was ample time for sharing ideas and, at least for me, it was one of the best meetings I have attended in a while! I will definitely attended the next meeting (likely 2019) and I encourage everyone who is tangentially involved in poeciliid research to attend too!

 

Exciting spring for awards

It has been an exciting spring in the lab! We wanted to acknowledge the awards that several students and postdocs received this spring.

Anthony Brown received the James R. King Graduate Fellowship from the School of Biological Sciences to fund his research and part of his stipend this summer!

Joanna Kelley received the College of Arts and Sciences Early Career Award!

Luana Lins received a scholarship to the Summer Institute in Statistical Genetics at University of Washington this summer and a travel award from the Society for the Study of Evolution to attend Evolution 2017!

Samantha Kallinen received the Undergraduate Summer Minigrant from the College of Arts and Sciences to support her research over the summer!

Allegra Sundstrom received the Youth Activity Fund award from the Explorer’s Club and a School of Biological Sciences research award to conduct research in Alaska this summer!

Congratulations to Shawn Trojahn – NSF GRFP!

Congratulations to Shawn for receiving the NSF Graduate Research Fellowship Program (GRFP)! We are thrilled for Shawn. This is a fantastic testament to his accomplishments and promise as a graduate student!

“The NSF Graduate Research Fellowship Program recognizes and supports outstanding graduate students in NSF-supported science, technology, engineering, and mathematics disciplines who are pursuing research-based Master’s and doctoral degrees at accredited United States institutions… For the 2017 competition, NSF received over 13,000 applications, and made 2,000 award offers.” from https://www.nsfgrfp.org/.

Welcome Intern Laura Helou!

Laura has arrived from France! We are very excited to have Laura visiting the lab for 5 months to work on detecting and annotating transposable elements in extreme species!

Laura obtained her Bachelor’s Degree in Microbiology at the Montpellier University (France) and now she is in the last year of a Master’s Degree in Bioinformatics at the same university. During her master’s degree she has done two internships and developed a strong interest for comparative genomics and the impact of structural variation on the evolution of species. She worked on benchmarking of several tools for the detection of structural variation in the rice genome.

Alex Fraik and Michael Saxton give their first presentations

Congratulations to Alex Fraik and Michael Saxton on presenting their first oral presentations at the School of Biological Sciences Graduate Research Symposium! They both gave great talks! The School of Biological Sciences Graduate Research Symposium is organized by graduate students annually and coincides with our recruitment event for visiting prospective graduate students.
