What goes up must come down: The ‘universal thermal performance curve’ that shackles evolution

Lapin syrjäisestä erämaasta löytyi Suomelle uusi lihansyöjähämähäkki
Liidokki-hämähäkkeihin kuuluva otus on Salmelan mukaan harvinainen myös muualla Pohjois-Euroopassa. Salmelan mukaan lajia tuskin olisi löytynyt nytkään, ellei se olisi sattumalta päätynyt palsasuolla olleeseen [pyydykseen] Kaldoaivin erämaassa.

Iberian harvester ant queens are cloning different species to produce hybrid workers
This new frontier in reproduction is referred to by the authors as "xenoparous," meaning the ant queens have a need to produce individuals of another species as an inherent part of their life cycle. The exact developmental mechanism of cross-species male cloning is still unknown, but the authors have some theories.
