Jacquelyn Gill@jacquelyngill.bsky.social · 4mo agoOn 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...

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.

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...
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.

@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
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

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
Quantitative image analysis applied to revise the taxonomy of the Palearctic Earophila badiata species group (Lepidoptera: Geometridae: Larentiinae)
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...
