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.

(Earlier: Why the UK’s butterflies are booming in 2025)
Why are we seeing so many butterflies in Ireland this year?
Another reason for the 2025 butterfly boom is the weather in Europe. Hot, dry weather creates drought, and butterflies capable of migration escape by altitudinal and geographical migration. By moving north, Clouded Yellow, Large White, Small White, Red Admiral and Painted Lady butterflies can find succulent foodplants for their caterpillars.

Menetyksiä pohjoisessa, tulokkaita etelässä – ilmastonmuutos muokkaa yöperhosten yhteisöjä eri puolilla Suomea | Helsingin yliopisto
Ilmastonmuutos muokkaa yöperhosten yhteisöjä eri puolilla Suomea. [Kylmiin] olosuhteisiin sopeutuneet lajit harvinaistuvat pohjoisessa samalla kun Etelä-Suomeen saapuu lämpimään sopeutuneita lajeja manner-Euroopasta.

Birds found thriving in a very large commercial forest in Maine
North America has lost an estimated 3 billion birds since 1970—a nearly 30% drop across species—mostly due to habitat loss and degradation. So when a team of researchers repeated a bird population study they did 30 years earlier in a very large commercial forest landscape in Maine, they were stunned to find more birds than before.
