The frequency of mowing affects the quality of the biomass entering urban food webs!
Michał Filipiak@michalfilipiak.bsky.social · 2mo ago🧵1/5 Lawns are usually managed and evaluated by what we can see: height, flowers, biomass, tidiness, or biodiversity. But mowing also changes what we cannot see: the elemental composition of plant biomass entering food webs: doi.org/10.1016/j.je... @ioes-ju.bsky.social @filipiakzuza.bsky.social
🧵5/5 Bonus for @mikekaspari.bsky.social Frequent lawn mowing can increase the sodium content of plants by as much as tenfold! I wonder if grazing might have a similar effect? doi.org/10.1016/j.je...
🧵4/5 Our key message: mowing is not only a technical or aesthetic practice. It is also a biogeochemical driver. Urban lawn management should consider not only biodiversity and biomass, but also the elemental quality of matter moving through urban food webs. doi.org/10.1016/j.je...

🧵3/5 This matters because plant biomass is not only “green matter”. It is a multielement resource for herbivores, detritivores, soil organisms and microbes. Changing its chemistry may change nutritional quality, stoichiometric mismatches and contaminant transfer in urban ecosystems.
🧵2/5 We studied roadside lawns in Kraków and Katowice under three mowing regimes: once, three times, or six times per year. Frequent mowing reshaped shoot stoichiometry: increasing P, K, Na and Mg, while decreasing several metals, including Pb.

Hej Blåmes! Gotland's long-term bird monitoring@hejblames.bsky.social · 3mo agoBut the good news is - blue tits are using our artificial feathers in their nest decorations, it’s the first year of the experiment so stay tuned in a year for the next steps! @ncn.gov.pl @jagiellonskiuni.bsky.social #gotland #birds #collaredflycatcher
Podczas wiosennych porządków w hodowli pszczół @ioes-ju.bsky.social w domku dla murarki ogrodowej znaleźliśmy… ptasie gniazdo! 🪹 Budki dla owadów mogą być domem nie tylko dla dzikich 🐝, ale też dla 🐞🕷️🪲, a nawet 🐦. Przyroda naprawdę nie lubi pustki. #DzikiePszczoły #PtasieGniazdo
Our paper is now out in its final form in @natcomms.nature.com ! We show that ancient insect symbionts can undergo extreme, convergent genome reduction to as little as ~50 kb - driven by ecological shifts and symbiont replacement. 🔗 www.nature.com/articles/s41... More below 👇 1/
Convergent extreme reductive evolution in ancient planthopper symbioses - Nature Communications
Symbiotic bacteria can have exceedingly small genomes. This study finds that ancient bacterial symbionts of planthoppers have repeatedly evolved the smallest known genomes, losing most biosynthetic fu...

What’s the catch of the day?
Warming oceans and evolution make fish less likely to be on the menu

Huge congratulations! Prof. Kozłowski's work in Science! www.science.org/doi/10.1126/...
Evolutionary adaptation to global change reduces sustainable fisheries yields
Global warming is altering the fisheries that underpin food security, but projections of these impacts generally exclude evolutionary processes. We describe a model that forecasts how fish will adapt ...

Piotr Lukasik@sympiotr.bsky.social · 6mo agoOur new paper in @natcomms.nature.com is now online-early! We describe independent evolution of bacterial genomes of only ~50–52 kb — the smallest known outside cellular organelles — revealing striking convergence toward minimal gene sets. 🔗 doi.org/10.1038/s414...
