#WPBO #RaptorCount started this week. We're fortunate to have Sean McLaughlin counting for us this Spring. His first blog post of the season is up!

Pair-bond strength is consistent and related to partner responsiveness in a wild corvid | Proceedings of the Royal Society B: Biological Sciences
The need to maintain strong social bonds is widely thought to be a key driver of cognitive evolution. Cognitive abilities to track and respond to information about social partners may be favoured by s...

Bright colors observed across the animal world are often used during mate choice. @dickmerrill.bsky.social explores a @plosbiology.org study of genetic & neural mechanisms contributing to evolution of visual mating decisions in Heliconius butterflies 🧪 Paper: plos.io/4iHQDRd Primer: plos.io/4ipW7QS
Left: Using genome-wide association analyses, VanKuren and colleagues show that separate loci within the K locus control a white-yellow color switch and contribute to variation in male preference, respectively, in a polymorphic population of Heliconius cydno in Ecuador. The full geographical range of H. cydno is shown on the map in light blue. The approximate location of the color pattern gene Aristaless-1 is shown for reference; other genes (not shown) are also present in the K locus, including some that are differentially expressed during the development of visual processing regions of the insect brain. In this and other H. cydno populations, white-yellow wing coloration correlates with the proportion of inhibited UV-photoreceptors, suggesting a compelling mechanism for the evolution of visual preference. Right: Individual ommatidia in the butterfly eye are composed of multiple photoreceptors. Inter-photoreceptor synaptic connections are known to exist within the lamina, the upper layer of the optic lobe, itself the region of the insect brain responsible for initial visual processing.
