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.

Absolutely thrilled you’re with us! đŸ€© I’ve seen you’re already a master at negotiating with great tits (those little devils!)— now we’ll see if they return the favour. Finland field season is going to be legendary. 🐩✹

Complementary approaches to measure predation pressure on butterfly populations in Australia Abstract. Predation pressure is a major force driving the evolution of anti-predatory traits, yet quantifying its intensity in the wild remains difficult.

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.

High detectability costs select weak warning signals in chemically defended gregarious prey Why do some chemically defended prey use weak visual signals when conspicuous aposematic coloration seems more effective for predator avoidance? Using weak

@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.

Quantitative image analysis applied to revise the taxonomy of the Palearctic Earophila badiata species group (Lepidoptera: Geometridae: Larentiinae) The geometrid moth Earophila badiata (Denis & SchiffermĂŒller, 1775), which occurs widely in the Palearctic realm, has rapidly filled a large gap in its range across southern Finland during the past tw...

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.

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
