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!

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🪶🧪🌍

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

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

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

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. 🧪🪶🌍

Hi @danirabaiotti.bsky.social ! It's @muriellealund.bsky.social here trying to migrate our lab's account to Bluesky on behalf of Pr. Anna Qvarnström. Thankful if we can be added to the science feed. Here is our official lab page: www.ieg.uu.se/animal-ecolo...
