Just south of the #Arctic Circle, we studied Red-necked #Phalaropes and uncovered that females arrive at the breeding grounds before males. And it’s not because they’re in better condition. The real mechanism remains a mystery...

Sperm sequencing reveals extensive positive selection in the male germline - Nature A combination of whole-genome NanoSeq with deep whole-exome and targeted NanoSeq is used to accurately characterize mutation rates and genes under positive selection in sperm cells.

Now published! Our paper on:
(1) Accurate sequencing of sperm at scale
(2) Positive selection of spermatogenesis driver mutations across the exome
(3) Offspring disease risks from male reproductive aging

Some papers arrive too early for their time.
Craig (1987) saw in a spider’s body size the seeds of diversification itself—an idea both simple and radical.
Evolutionary biology is still catching up.

What if sheet-web weaving acted as a diversification engine in #spiders. Unlike costly orb/space webs, sheets are cheap, flexible, and protective. Strikingly, 25 of 112 families (≈22%) are sheet-web weavers, the largest guild. Coincidence? Tree from Cardoso + doi.org/10.1371/journal.pone.0021710

Working on #protogyny in the Red-necked #phalarope got me thinking that some day I'm going to do the same map but for this species
