Have any of your biologging devices ever failed? ⁉️ If so, we’d like to hear from you! 👂 Researchers at Acadia University, Nova Scotia, are investigating biologger device failure rates to help improve research practices. 🎓 The survey takes just 10 minutes to complete: forms.gle/fZW9n2dojJVB...

Wondering how diel activity rhythms change across latitude? Check out Tash’s new paper. TLDR, Kittiwakes, a seabird, are flexible and range from 24-h rhythms at low latitude and appear to free-run or be arrhythmic at high latitude 🧪🪶🌍🦑

True story.

New snow bunting research from our friends working in Iqaluit, Canada. Found that snow buntings breeding there have a broad longitudinal wintering range. Paywalled, so will have to wait until I’m in the office to read the entire article 🧪 🪶

Can confirm. The warmth is unseasonable here. Many of us are sorely missing snow for under our skis, and didn’t help that we had a misty rain today… www.information.dk/udland/2026/...

The streets were full today in Nuuk. #Greenland had something to say 🇬🇱 Notice how the stream of folks stretches the length of the street in the left photo. Behind is just as packed for just as long. Nuuk is only ~20,000 people. This was a very large portion of the city.

How do birds sense the magnetic field to navigate? The research field is slowly coalescing around a quantum mechanics mechanism described in the thread below. #Ornithology 🪶

Happy solstice ❄️ In the Northern hemisphere we have our shortest day of the year. In Nuuk the sun came up at 11:21 and will go down at 15:27 (3:27pm). How much daylight do you have for the solstice?

Do songbirds align (migratory) flights to a specific part of their diel rhythm? In the snow bunting, nope, it’s flexible, but they keep a 24-h rhythm year round, even in Arctic summer. Includes a glossary of chronobiology terms relevant to ecology and migration 🪶 🧪 🌍 dx.doi.org/10.1002/jav....

🚨NEW PAPER🚨 We've already shown mosquito infections vary by time-of-day, here we test whether infection of mice FROM mosquitoes vary in a rhythmic manner. We test this in untreated & drug treated mice as some fitness consequences are only apparent in stressful environments doi.org/10.1186/s130...

Circadian rhythms are pervasive and affect many different biological processes. Can engineering the circadian system improve agriculture across latitudes? 🧪 🌍 Natural populations may not have the same ability to extend to new latitudes bc of the lack of phenotypic plasticity or genetic variation
