This month we are saying farewell to Beth -- who has been the beating heart of our lab community for years -- as she embarks on the next exciting chapter in her career. 

Beth has been awarded a prestigious Prize Fellow to launch her independent research group at the University of Bath in the UK, where she will join a cohort of talented PIs forming a new research cluster focused on the microbiome. Because Beth will be there, it is sure to become an exciting epicenter for excellence in the field. Students and junior researchers who are interested -- take note!

We will all miss Beth, but we take heart in knowing that we can continue to collaborate and learn from her for years to come. What an all-star she is...!!

The upshot: The gerbils that are the best jumpers are not necessarily the best maneuverers, and vice versa. Led by Courtney Reed, the Kartzinel Lab ran a series of controlled laboratory tests to discover that each individual's decision in the pivotal moment it meets a predator may be enabled by -- or constrained by -- the anatomy of its hind limbs. The paper Distinct morphological drivers of jumping and maneuvering performance in gerbils was published in Journal of Experimental Biology!

Earlier this month, Mary Burak led a workshop together with Save the Elephants and the National Museums of Kenya. The meeting convened at the Save the Elephants headquarters at Samburu, and the team spent a few days learning to collect voucher plant specimens for DNA barcoding. In a very short period of time, they added an important chunk of regional plant diversity to the collections available for barcoding. The training and work completed will dramatically increase our ability to precisely characterize the diets of elephants across Kenya. It was super gratifying to see such a great group of scholars, conservationists, long-time collaborators, and all-around quality people coming together to do such important work. Mary shared some great photos of the team in action: Paul Musili, Rispa Kathurima, Gideon Galimogle, and Evans Nawasa.

A new paper from the lab was led by postdoc Bethan Littleford-Colquhoun and published in Royal Society Open Science: "Body size modulates the extent of seasonal diet switching by large mammalian herbivores in Yellowstone National Park." The paper is free to read and download.

Beth used cutting-edge genetic and GPS-tracking technologies to test age-old ideas about why animals select the foods that they do. The work involved collaboration from experts in wildlife ecology and management, genomics, remote sensing, and botany -- with contributions from the National Park Service, several citizen science organizations, and funding from NSF as well as the Department of Interior. 

As Beth summarized in an interview with News@Brown, we have come to more accurately understand wildlife populations as a collection of animals that can respond individualistically to changes in their environment. From summer to winter, animals have to radically change the kinds of foods they eat. But it's not just that: they also have to take care to update their overall foraging strategy as they shift from foraging socially as part of a large herd to foraging more independently for their own unique sets of resources.

Congratulations to Bianca Brown, microbiome scientist extraordinaire, on her publication appearing today in Ecosphere! Spatiotemporal variation in the gut microbiomes of co-occurring wild rodent species is freely available via open access. It is a rare example of the type of insightful work that can develop through collaborations involving field, lab, and big-data analytical approaches to really understand what's going on with wildlife. It is part of our long-term collaboration with the UHURU project at Mpala Research Centre in Kenya.

The lab is thrilled to welcome Joselyne Chavez and Montana Stone to Brown! Both are keen to use combine ecological field experiments in with genomic lab technologies and computational approaches to advance our understanding of biology in a major way while also contributing to meaningful conservation. We couldn't be happier about the time we will get to have working with these top-notch scientists--they are both off to a great start!

I am extremely excited to share a new job opportunity as a core member of our group: Lab Manager in Ecological Genomics at Brown. 

​This is such a unique career opportunity in our field. The position will be salaried, starting around $60,000, and it is expected to provide job security, stability, and community over the long term. There will also be opportunities for career growth as we work together to establish a new Ecological Genomics center via Brown’s Genomics Core Facility. You will be able to help shape the future of your own position.

From an insider's perspective, we very rarely see opportunities as good as this one. The formal job ad is pasted below.

Please feel free to distribute via your networks or social media to help ensure any potential candidates you know may apply.

The lab is incredibly excited to welcome Mary Burak! Mary is joining the lab as a Fulbright Scholar based in Kenya followed by an IBES Voss Postdoctoral Fellowship. Together these prestigious awards will support Mary for three years both in Kenya and at Brown. Mary will collaborate with a number of major NGOs as well as scholars at the University of Nairobi, the National Museums of Kenya, and Mpala Research Centre to address critical data needs for the conservation of large carnivores and herbivores across Kenya. 

Mary completed a PhD in Os Schmitz's lab at Yale University in 2023. She is a star and we are so keen to learn from her and collaborate with her over the next few years and beyond!

The paper led by Brian Gill on individual-level tracking of elephant diets -- Foraging History of Individual Elephants Using DNA Metabarcoding -- was just published by Royal Society Open Science. We are very proud of this paper, which revisits a set of classic studies on seasonal diet switching by elephants using stable isotopes in hair that were led by coauthors Thure Cerling and George Wittemeyer. The work was made possible with support in the field from Save the Elephants and with the botanical expertise of coauthor Paul Musili from the National Museums of Kenya.

The paper was accompanied by a great summary by Corrie Pikul and featured on the Brown University homepage: Similar to Humans, Elephants Vary What they Eat for Dinner. 

The paper also attracted attention in the media, including interviews on BBC Television and Times Radio. Some nice coverage of the study was also provided by BBC (with hilarious photos), Newsweek, ZME Science, and The Times.
