We tested wild Araneus diadematus with an auditory stimulus: a 400 Hz sound triggering a stereotyped "leg raising" reaction. Active spiders reacted fast irrespective of night or day. Immobile spiders during the day? Also fast. Immobile spiders at night? Much slower! 🧵2/5

🚨New paper🚨 Garden #spiders are everywhere right now—big, beautiful ladies, still in the hub of their 🕸️ But they are not just waiting, at night they also 💤! We found behavioral signatures of sleep in the wild. Out in #AnimalBehaviour w/ @mherberstein.bsky.social tinyurl.com/uznvv58y 🧵1/5

Adult female garden spider (Araneus diadematus) sitting at the center of her orb web, with orange‑brown legs and a patterned abdomen. The web’s radial and spiral threads are sharply visible, catching the light. The background is blurred green foliage with soft circular highlights, making the spider and web stand out in clear focus.

“Jobs” is where you manage all the jobs you’ve created. You can start or stop jobs and monitor their progress. If your computer has multiple GPU/CPU cores, you can even choose to run jobs in parallel for a nice speed-up.

“Combine” allows you to concatenate multiple videos while adjusting the encoding settings in one go. Optimal if - like us - your cameras start new recordings every hour.

“Compress” allows you to change the encoding of a file, which often means compressing to save space. But it can e.g. also be used to change your “.mov” file to “.mp4” or lower your frame rate.

“Clip” allows you to clip in both space and time! You can make cropped regions and/or choose time intervals, and get all the combinations.

Our postdoc @roald-arboel.com made a thing! #Croppy is #free and awesome for fast and effective #video #editing and it has a #GUI! Need to crop a part of a video? Need to trim a video? Need to combine videos? Need to compress a video? roald-arboel.com/croppy/

Finally taking spider 🕷️ sleep 💤 to the wild! Currently in QLD, Australia, filming Portia fimbriata sleep in the field-which disturbances are they facing and how does their wild sleep compare to lab sleep? Stay tuned! 🙃 ps- terrible place to work 🤭 @nadjageiger.bsky.social @mherberstein.bsky.social
