Bob May, one of the brightest theoretical ecologists, recently passed away: a beautiful portrait in Nature. #science #ecology #population #biology
A new study of captive flamingoes found they prefer to hang out with their flaminbros, and some individuals could even be considered social butterflies.
"Some flock members avoided each other entirely and never crossed paths. A few even displayed signs of aggression when coming in close quarters with individuals they appeared to dislike." I get that

Wow. Dr. Ross Pipe has released a free PDF of his book, Animal Earth.
"Animal Earth is an impartial celebration and exploration of animal diversity, drawing on the latest research into how the animal lineages are related, how they live and their origins. It’s 320 pages long and is illustrated throughout with 540 spectacular colour photos, SEMs and illustrations"

Interesting side effect of #gender determination by sex #chromosome. Because their sex chromosomes differ, male humans (XY) or female bids (ZW) may be more exposed to recessive deleterious #mutation, as suggested by a broad meta-analysis. #science #biology #survival
