Closing time effect: towards the end of the mating season, your acceptance threshold decreases (or the partner's attractiveness increases). Congratulation to Louise for this nice theoretical analysis.

90 years old and still snappy. A vivid interview with the “intellectual grenade thrower” ecologist and evolutionary biologist, Ed. O. Wilson. He has challenged well-established dogmas, he has expressed many controversial views, he was even arguably wrong several times, but what an inspiration for generations of ecologists!

mating (partners resemble each other) is a central question in evolutionary biology. A meta-analysis in species reveals that such a pattern may be less common than previously thought, mainly due to publication bias.
