Curious how birds find their way? 🧭🐦
Analyze decades of ringing data to study abnormal migratory routes and uncover what these deviations can reveal about the mechanisms guiding birds on their journeys. Drop me an email for details! #ornithology

This is very cool tech. Do you know whether there a step by step guide or any articles out there with very descriptive methods that could be adapted to teach students how to use RUBY?

Can’t sleep?

Tune your (internal) clock. Go outside in the middle of the day. Reduce those night time lights and midnight snacks.

The Danish national news published a collection of photos from seabird work in Greenland taken by Carsten Egevang.

The pics are great illustrations of my previous haunts, and one of me looking particularly scruffy is buried in the bunch 🪶 #Seabird

1) Acknowledging the difference between causes and consequences of segregation.
2) acknowledging that spatial or temporal segregation is not in and of itself a cause to segregation.
3) discussion of the selective forces that can cause the segregation.

Migratory birds aren’t equally efficient at all speeds. A new Lund University study shows thrush nightingales fly most efficiently at 7–8 m/s – the speed they actually use on migration.

Crazy discovery in ants 🤯🐜

"Males from the same mother exhibit distinct genomes and morphologies, as they belong to species that diverged over 5 million years ago."

In a case of obligate cross-species cloning, female ants of Messor ibericus need to clone males of Messor structor to obtain sperm for producing the worker caste, resulting in males from the same moth...

I don’t have much data right now, but shoot me an email and let’s see whether I can contribute anything

Yes definitely. We use estimated age for chicks or lay date for eggs to get an approximate hatch date for long term monitoring of phenology. We often only have the resources to visit a site once per year for raptors because they nest spread out.

In this example, is doesn’t need to be on the spot

I’m not really into it yet, but I know we do this for falcon eggs we come across in nests

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

Delighted to share the lab’s first independent publication, a Tansley Insight in @newphyt.bsky.social where we analyse new crop genomics studies to show how we can engineer plants that can grow at different latitudes (key for climate-smart Ag) nph.onlinelibrary.wiley.com/doi/10.1111/...

New review in PRX Life, where we propose a tangibility scale for the physics of social interactions, and highlight a few tangible examples - from dead fish “swimming” to efficient schooling, warm penguin huddles, and dry ant rafts.

Looking forward to reading this!

What about entrainment of multiple oscillators? I speculated (briefly) about this in one of my PhD chapters but didn’t know this was a field of research. Could be fun to investigate in more depth
