@koskenpato.bsky.social @caritalindstedt.bsky.social Why stay cryptic if chemically defended? In pine sawfly (Neodiprion sertifer) larvae, higher conspicuousness reduced survival. Weak warning signals may rely on behavior and grouping. academic.oup.com/beheco/advan... #Aposematism

Thrilled to announce a Postdoc opportunity in our group on the evolutionary genetics and ecology of colour. Wonderful system, great collaborators, and room to shape your own ideas. Apply by 7 Jan: jobs.helsinki.fi/job/13477181...
Measuring predation in the wild is hard. @mherberstein.bsky.social We compared wing damage, artificial replicas, and bird surveys in Australian butterfly communities. Methods were complementary — together they better estimate predation risk. royalsocietypublishing.org/rsos/article...
With @nathist.bsky.social we revisited the Earophila badiata complex by using: Quantitative wing image analysis Genitalia + micro-CT mtCOI barcodes No support for several named taxa → synonymies proposed; fennokarelica reduced below subspecies rank. peerj.com/articles/206... #IntegrativeTaxonomy
Oh! Our #biomimetic, #aposematic #wind turbine paper is out! @grahancock.bsky.social put together a fantastic short video explaining the study — so if you don’t feel like reading the paper, here’s the nutshell version! @helsinki.fi @behavecol.bsky.social www.youtube.com/watch?v=Rg41...

WP is clueless. The judgment is not about religious views/convictions. The judgment concerns author's (she is a doctor) medical views. False and derogatory medical claims made within the context of religious scripture do not enjoy the protection of religious freedom.

This is an exciting opportunity to work in Helsinki, and in collaboration with us in Cambridge… on moth colouration. Could focus on the role of Ivory long non coding RNA in regulating melanisation…

The geometrid moth Earophila badiata (Denis & Schiffermüller, 1775), which occurs widely in the Palearctic realm, has rapidly filled a large gap in its range across southern Finland during the past tw...

Abstract. Predation pressure is a major force driving the evolution of anti-predatory traits, yet quantifying its intensity in the wild remains difficult.

On NSF’s postdoc page, the biology and earth science fields have been completely eliminated; the only remaining fellowships are in math, astronomy, engineering, and “entrepreneurship.” Weird choice not to support research on the life support system for 8 billion people. www.nsf.gov/funding/post...
