Led by Viktoriia Radchuk, an international collaboration shows phenological shifts in response to changing temperatures allow populations to remain stable or even increase in numbers.

A selection of studied species is shown, with each inset giving information for that species on its generation time (T, in years; also depicted by the black bar next to it), its diet (carnivore: C, herbivore: H, and omnivore: O) and whether the species is a migrant (M) or a resident (R). The inset shows the number of studies per taxon and trait category. Illustration credits for the species pictures taken from Wikipedia: Svalbard reindeerโ€”Bjรธrn Christian Tรธrrissen, four-striped grass mouseโ€”C.R. Selvakumar, silver gullโ€”JJ Harrison, snow petrelโ€”Samuel Blanc, northern giant petrelโ€”Liam Quinn, green turtleโ€”Brocken Inaglory, green-rumped parrotletโ€”Jam.mohd, Columbian ground squirrelโ€”Martin Pot, red-winged fairy-wrenโ€”John Anderson, grey-headed albatrossโ€”John Harrison. Two species pictures were provided by the co-authors of this study: painted turtle (credit: FJ) and Atlantic yellow-nosed albatross (credit: SOp).

In Nature Communications, our paper led by Viktoriia Radchuk shows that phenological change mediates global vertebrate responses to temperature. The study compiles 213 time series of phenotypes and population sizes, including data from Bylot. Read: urls.fr/w7ZKp9 @natcomms.nature.com ๐Ÿงช๐ŸŒฟ๐ŸŒŽ๐ŸŒ๐Ÿฆ‰๐Ÿฆ‘๐ŸฆŠ๐Ÿปโ€โ„๏ธ

For urban birds, vegetation acts as a natural buffer against urban stress. Even vegetated noisy areas can support high functional diversity, when human access is restricted.

Graphical abstract for a manuscript titled "Too few, too many, or just right? Optimizing sample sizes for population-level inferences in animal tracking projects". The workflow presented in this manuscript evaluates sampling design by assessing sampling duration, sampling interval, and the number of sampled individuals needed to obtain reliable population-level estimates.

Published ๐Ÿ“– ๐Ÿฅณ In a new meta-analysis @mariusgrabow.bsky.social studied whether subtle infection, traditionally often considered as relatively benign, affect phenotypic and demographic traits. Using avian blood parasites, causing #avianmalaria as an example, we performed a systematic review ๐Ÿงต

Wenn Parasiten den Flug bremsen Eingeschrรคnkte Bewegung von Staren mit Parasiten-Infektionen wirkt sich negativ auf deren Nachwuchs aus Pressemitteilung von Leibniz-Institut fรผr Zoo- und Wildtierforschung, TU Berlin und Uni Potsdam

๐Ÿฆ Eine gemeinsame Studie von #TUBerlin, @unipotsdam.bsky.social & Leibniz-IZW
zeigt: Mit Blutparasiten infizierte Stare bewegen sich weniger, suchen in schlechteren Gebieten nach Futter & ihre Kรผken sind im Schnitt 12% leichter. Das kann gravierende Auswirkungen auf nachfolgende Generationen haben.โฌ‡๏ธ
