A wonderful team effort to characterize the actions of HSD17B2, a gene that helps some #ruff males to dial down their testosterone levels, got published @science.org (1/n)

Science Magazine @science.org · Jan 23

A single gene underlies male mating morphs in ruff sandpipers, a new Science study finds. The results show how evolutionary changes in a single gene's structure, sequence, and regulation can drive significant diversity within a single species.

A breeding ruff male (Calidris pugnax) in alert posture scans the breeding area for mating opportunities at Liminka Bay, Finland. Ruff males deploy one of three mating tactics that differ in aggressive and courtship behaviors. Differences in aggression between tactics are tied to concentrations of circulating androgens, which are modulated by the actions of a single gene.

Looks like a mesmerizing new paper!

Amazing riflebirds! We did not dare to write that males 'mesmerize' females with their spectacular displays, but .... judge yourself!

‘We’ve done it before’: how not to lose hope in the fight against ecological disaster

Some days it can feel as if climate catastrophe is inevitable. But history is full of cases – such as the banning of whaling and CFCs – that show humanity can come together to avert disaster

Our new study shows that, for the three vastly different examples and 38 other species, the way how survival & reproduction respond to threats is also vastly different! But, overall, populations fluctuate strongly when several climatic variables change in tandem: doi.org/10.1093/pnas...

Comparative life-cycle analyses reveal interacting climatic and biotic drivers of population responses to climate change

Abstract. Responses of natural populations to climate change are driven by how multiple climatic and biotic factors affect survival and reproduction, and u

1/Spring bird migration is getting earlier, right? Not necessarily! In our latest paper, led by former lab MSc student Lauren Puleo, we found that a population of Hudsonian Godwits breeding in Alaska is now arriving 6 days later than they were a decade ago. royalsocietypublishing.org/doi/10.1098/...

Flexibility in the face of climate change? A rapid and dramatic shift towards later spring migration in Hudsonian godwits (Limosa haemastica) | Proceedings of the Royal Society B: Biological Sciences

I really enjoyed this one, a beautifully written natural history account about lekking in birds. And the Darwin-Wallace argument over sexual selection never gets old.

5/5 In addition, a huge effort is made to protect the #critically #endangered southern #dunlin. With expertise of Vroni Rohr-Bender and others, 26 chicks got an advantage be growing up in our aviary, before they got released back in the meadows, hopefully successfully #boosting the #population.

4/5 Most time of the field season was spent searching for nests and to ringing the #chick and #adult ruffs. We found 65 nests in total which is an excellent result. Adult birds also got a radio or #GPStag to investigate #habitat use and behaviour. Aren't the chicks cute?

3/5 Independent males have striking colours and are #aggressive. #Satellite males are mostly white coloured and have more #sneaky behavior. Female-looking faeders are extremely rare.

Here an independent male is pecking a satellite to show its dominance.
