Last week the annual @animecol-uu.bsky.social symposium, 'Revolution', counted with several presentations from the students and researchers in our lab! Yishu Zhu, Ana Gomes, Sophia Stratton, Michaëla Berdougo, and Anna Qvarnström presented the most recent updates on the flycatchers work!

Master Projects available in the Qvarnström lab @qvarnstromlab.bsky.social studying climate adaptation and speciation using a natural flycatcher hybrid zone on Öland, Sweden! Check available projects here 👇👇 drive.google.com/file/d/1B69x...

A new MSc fledging the lab. Congrats Jonavan!

Congratulations to Jing Jonavan Leong on defending his master thesis looking at effects of environmental factors on early and late growth rate in nestling collared, pied and hybrid flycatchers!!! It was fun working with you on this project! @qvarnstromlab.bsky.social @animecol-uu.bsky.social 🧪🪶🌍

A new study finds that "nature-based experiences, and birdwatching in particular, increase well-being and reduce distress" on college campuses. More of this, please! www.sciencedirect.com/science/arti...

And the 2024 field crew is now complete and ready to measure a few hundred flycatcher pairs and their nestlings! The woods are beautiful and full of birds who are currently very busy building nests and laying eggs! #olandflycatcheryear23 @muriellealund.bsky.social @jacanajones.bsky.social 🧪🌍🐦🪶

Yishu Zhu presents her PhD's half time seminar @animecol-uu.bsky.social, summarizing her research questions, results & plans for the end of her thesis.Let's dive into high resolution metabolic measurements, evolution of mito-nuclear incompatibilities & divergent climate adaptation in flycatchers🪶🧪🌍

Congrats to Jing Jonavan Leong on presenting his master thesis research on the effect of temperature on growth rate in collared, pied and hybrid flycatcher nestlings. @qvarnstromlab.bsky.social @animecol-uu.bsky.social 🧪🪶🌍🐛🌡️📈 evolution

Flycatchers next: Yishu Zhu showed exciting results on mitochondrial performance in relation to competition in nestlings & I spoke about the molecular basis of interactions between sperm & reproductive tract fluid in these hybridizing birds @qvarnstromlab.bsky.social @animecol-uu.bsky.social 🧪👩🏼‍🔬🪶🌡️🐛

Sexual selection can be good, bad & ugly with negative consequences of sexual conflict for population demographics. David Berger @dbergerbiol.bsky.social shows that these effects may be reversed when environmental complexity is considered. onlinelibrary.wiley.com/doi/full/10.... 🌍🧪evolution

Environmental complexity mitigates the demographic impact of sexual selection

Anna Qvarnström @qvarnstromlab.bsky.social presents: "inheritance of wealth" (territory quality) in collared flycatchers.We looked at phenotypic & genomic predictors of resource acquisition over 20years on Öland. Work under review together with @erynmcfarlane.bsky.social & many others. 🧪🌍🪶Evolution

Uppsala Uni's Animal Ecology program is here, give it a follow! Our annual symposium is on its way, highlighting the diversity in amazing research on all things evolution, covering insects, birds, fish, mammals, reptiles, amphibians & their relationships with plants, microbes & viruses. 🧪🌍🪶🐙🦑🐯🌿🦠🦎🧬

'Revolution' happens tomorrow (our annual 2-day programme symposium) Many will present their research. Invited speakers are Caroline Isaksson, Lund University and Luc Bussière, University of Gothenburg who will share their findings and scrutinise our 'revolution' 👀 Exciting days await us!

New paper: "Synthesis and Scope of the Role of Postmating Prezygotic Isolation in Speciation",where we review mechanisms & importance of barriers acting after mating before fertilization in promoting &/or maintaining species divergence. 🧪🌍🪶🦑🌿🐯🐙#evolution m.cshperspectives.cshlp.org/content/earl...

Germline removal increased stress resistance in both sexes, but increased lifespan only in males, and only when high costs of mating were excluded (above). Germline removal reduced growth but more so in females. Germline maintenance seems costlier for males than for females. 2/2

Congrats on your master degree Nicholas!

Murielle Ålund (she/her)@muriellealund.bsky.social · 3y ago

Congratulations to Nicholas Ruello for successfully defending his master thesis, done last Spring with the @qvarnstromlab.bsky.social at Uppsala on neophobia in flycatchers, and receiving the top grade from the University of Bologna! It was really fun working with him on this project! 🧪🌍🪶#evolution

New paper out at #evolution: "Tracking hybrid viability across life stages in a natural avian contact zone" Group effort taking advantage of our rare dataset tracking hybrids for nearly 2 decades, and comparing their performance to pied & collared flycatchers across their whole life. 🧪🪶🌍

Murielle Ålund (she/her)@muriellealund.bsky.social · 3y ago

Group effort by @qvarnstromlab.bsky.social with @carosegami.bsky.social Yishu Zhu @pnkmenon.bsky.social @jacanajones.bsky.social. We find signs of hybrid inviability in a system where we only knew about sterility, but also surprising demographic patterns only detected thanks to long term data! 🧪🪶🌍

The Qvarnström Lab is here! Follow for all the latest research from them! 🧪🦅🌏
