Wow, there seems to be no end to the editorials that blame scientists for “lack of public trust”. And that completely ignores governments and politicians and billionaire media owners who attack science and lie about science. We cannot communicate our way out of this.

Questions of public trust can be addressed only through better communication and research that meets society’s interests, says Peter Gluckman go.nature.com/4xekdFo

If “party leadership and centrists immediately fall behind El-Sayed to defeat the Republican” does not align with your priors about the Democratic Party you should both reflect on why and also update those priors

I always loved the Mike Rosenzweig paper that framed a frequency dependent fitness landscape as a sphagnum bog (which is like walking on a waterbed) it deforms downward under the weight of the mass of the average phenotype in an evolving population, so there’s disruptive selection wherever you stand

Awesome #SICB interview with @yuchenchen0531.bsky.social about our recent collaboration with @elizabethhobson.bsky.social to study sex variation in aggression in monk parakeets!

In gregarious species, aggressive interactions often mediate the establishment of social rank and dominance hierarchies. Following the assumption that females and males compete under different selection pressures, many studies examine aggression and dominance in each sex separately. However, social selection pressures such as competition for resources or social status may influence the sexes similarly, and more work is needed to directly examine the role of sex in aggression and dominance. To address this, we compared aggression levels, choice of aggression targets, and dominance hierarchies between sexes in captive, mixed-sex groups of highly social monk parakeets (Myiopsitta monachus). We examined interactions at the individual, dyadic, and group levels in 5 groups of 10 individuals each. We asked whether sex predicted aggressiveness, choice of aggression targets, and social rank. We found no evidence that one sex was more aggressive than the other. In most cases, sex did not impact the choice of target in an aggressive interaction. The sex of an individual did not significantly predict the rank they achieved in the group; females and males were equally likely to be high-ranked. Overall, we found that sex had limited impacts on aggression and rank in these mixed-sex groups. Our study provides new insights into social aggression and dominance in monk parakeets by examining both sexes and highlights the importance of studying sex similarities and differences within complex social environments.

As Measles cases hit a 35 year high, as a senseless war rages on with no exit plan, as gas climbs to record highs, and the Epstein files remain secret, the U.S. Senate is holding a hearing today to yell at Dr. Fauci and again push horse dewormer on the American public.

It bears reminding our disgruntled friends in science that everything in this report that addresses your fondest desires isn’t going to work out the way you think. It’s put there as bait to attract you. It will turn to ash in your mouth. Because the goal is destruction and transfer of public dollars

“A New Golden Age, in contrast, is a grab bag of political grievances, half-thought-through justifications for policies the Trump administration was already pursuing, and insinuations that scientific experts are kind of annoying and should learn how to fix car engines.”

This paper is so freakin' cool. The authors use a combination of comparative anatomy, the fossil record, phylogenetic methods, and morphometric analysis to figure out how (and when) seals evolved "amphibious hearing" that uniquely enable them to effectively hear in both air & underwater

Dr James Rule@palaeo-jrule.bsky.social · 4w ago

Seals have a superpower: they are the only mammals with amphibious hearing! They hear well both in-air and underwater. My collagues and I have a new study in Proceedings B on the origins and evolution of amphibious hearing in pinnipeds 🦭🔊🧪 doi.org/10.1098/rspb...

Biological sex is binary, except when it’s not (isogamy). It’s defined by gamete size, except in large-spermed males. It’s binary, but one can be both at once (hermaphrodites), neither (sterile) or switch (clownfish), and it might depend on temperature (crocodiles) or parasites (Wolbachia). (1/3)

Ben Allen@evodynamics.bsky.social · last mo.

Defining sex based on gamete size is a choice. Perhaps it's the most parsimonious of all binary single-criterion sex definitions. But to claim that gamete size is the "ultimate defining criterion of biological sex" (whatever that means) falls into the naturalistic fallacy the authors warn of.
