Guschanski lab: News

April 2019

Three new people have joined the group! Welcome to Katia, Alice and Zach!

Our paper on how gorillas interact with their dead, published in PeerJ came out and hit the nerve of media and the general public.

The members of the Chimanuka group inspecting the body of a dead silverback

Not only did we receive international coverage (see a few links below), but we also inspired one of the readers to compose a poem. This work is based on extremely rare observations and includes three independent instances of mountain and Grauer’s gorillas reacting to the death of their group members and an extragroup male. Katja happened to be in the right place at the right time during her trip to the DRC in 2016 and has witnessed the latter event. Amy Porter, the lead of the paper, has produced amazingly detailed observations and recordings of this event. Check out the videos associated with two of the rare encounters:

Interview with Swedish Radio (Vetenskapsradion).

Henrique receives the SMBE undergrad travel award and will be presenting his work on dental calculus in Manchester. His first conference! We all are super happy for him!

Catu (Catalina) and Tom will be presenting their work at the International Congress for Conservation Biology (ICCB) in Kuala Lumpur. Catu was selected for a speed talk on our Dryas monkey project and received a travel award! 

March 2019

Tom’s index hopping paper is published in Molecular Ecology Resources. Not only do we directly quantify index hopping rates but we also show the impact of even low index hopping of <1% for population genomics inferences. Beware of index hopping!

Katja is an approved docent now, for whatever it’s worth.

Katja travels to Mexico as part of the renown Frontiers in Genomics Program at UNAM. Smart, curious and open-minded students, amazing food, and a beautiful country! What could be better? 

February 2019

Jaelle presenting her first results on the dental calculus project at the Oikos meeting!

January 2019

Two new(ish) lab members joined out group. 

Yuhong Li is a Bachelor student at Uppsala University via Shandong University in China. Her exceptional drive and motivation will certainly lead to great results in her Bachelor project!

Tuuli Larva has rejoined our group after a break and will continue her project on gorilla genetic diversity. We are looking forward to exciting results!

Katja has given her Docent lecture on “Time travel for animal conservation” and is now awaiting the decision by the Docent committee. 

December 2018

Our work on the genomic consequences of recent population decline in eastern gorillas has now been published in Current Biology (https://authors.elsevier.com/a/1YMG53QW8RmXST). This collaborative project between our group and Love Dalén at Natural History Museum in Stockholm has received quite a bit of media coverage. Here are a few of my favourite pieces:

We went out on a great lab outing to celebrate the winter season. Lots of fun in snow-covered Swedish forests with Catu, Henrique, Tom, Jaelle and Thijs, building a snowman who turn out to look very much like Albert Einstein.

November 2018

Much has happened since the last update, so here is a short re-cap:
- Thijs Hofstede has joined our lab as Bachelor student intern to get into the depth of work in the ancient DNA lab. He is our saviour and the only reason we are on track with data production for the SciLifeLab National Sequencing Projects!
- Joint success for Jaelle Brealey and our former MEME Master student Rebecca Hooper! Their great work on the skin microbiome of killer whales has been published in Molecular Ecology. 


- Conference season was very successful for our group. Both Tom and Riana got accepted for the highly selective presentations of a talk and a poster, respectively, at the ESEB 2018 in Montpellier and Jaelle presented her work at the IGC Symposium for Microbial Eco-evolutionary dynamics in Lisbon. 

August 2018

We are happy to welcome two new members of our group, Catu and Henrique. Catu joins us as a visiting researcher to run a computational project on the speciation of guenons. Henrique will dive into the challenging world of non-human dental calculus. 

May 2018

Our study on historical changes in Grauer’s gorilla mitochondrial diversity is published in Scientific Reports. We show that the loss of peripheral populations, not population decline per se, is causing the reduction in mitochondrial genetic diversity in this critically endangered gorilla taxon. 

Two members of the Guschanski Lab will be presenting at ESEB 2018 in Montpellier. Tom will give a talk on his large-scale genomic study of mutational load in vertebrates and Riana Minocher will present a poster of her research project on Grauer’s gorilla gut microbiome.

January 2018

First first-author paper by Pauline Baas is published in the American Journal of Physical Anthropology! This work is based on Pauline’s Master project on Grauer’s gorilla genetic diversity and population structure. Really happy that all the hard work that Pauline put into this project has payed of. 

Warm welcome to Wenbo, who joins us for his research training on dental calculus analysis. 
 

December 2017
Our lab receives one of the SciLifeLab National Biodiversity Project grants. Great sequencing ahead!

August 2017
Jaelle Brealey joins our group as our first ever postdoc! Jaelle will be studying how climatic and demographic factors are reflected in the oral microbiome of mammals.

July 2017
Tom presents our study on temporal changes in eastern gorilla genetic diversity at the SMBE 2017!

June 2017
Lab hike of Guschanski lab. A fantastic group of people has joined us over this summer and many cool projects are now underway. Thus, it was time to get out into the nature and enjoy the beautiful Swedish summer (as long as it lasts)!


March 2017
We are happy to welcome Beki Hooper and Riana Minocher as our newest group members. Both will be working on microbial communities in social animals. Beki, co-supervised with Andy Foote (Bangor University), will explore the skin microbial profiles of killer whales. Riana’s project focuses on evaluating social, seasonal and ecological impacts on Grauer’s gorilla gut microbiome. Now we are finally complete for this semester!

February 2017
Happy to welcome our newest group member, Peter Niehoff. Peter will be working on the understudied Grauer’s gorillas, genetically characterising an new population of these magnificent animals. 

Welcome to Kevin Mulder, who joined us for a 5-months-long internship and will be involved in all our ongoing wet-lab-based projects. 

January 2017
We are very excited to welcome our two new students to the lab. Kristaps Bebris will be doing his Master project with us, helping us to see if DNA capture data can be used for bacterial community composition analyses. Tuuli Larva is evaluating fecal extraction protocols for their suitability for metagenomics studies. 

November 2016
We received grants from the Swedish Research Council FORMAS and The Royal Physiographic Society of Lund!

September 2016
Uppsala PhD students have hosted the 22nd European Meeting of PhD Students in Evolutionary Biology EMPSEB22 on Gotland this year and Katja was invited as a speaker. It was great fun to exchange with everybody and to talk about our current primate work.

September 2016
Together with Elisabeth Bolund and David Berger, Katja has organised the Ecology of Genome Evolution Symposium at Uppsala University. It provided a stimulating forum for exchange between external and local speakers and students, and ended with an outdoor panel discussion in the late summer sunshine.
