Correction: the record minus year was 2024, not 2022. Should also be corrected now at SverigesRadio's site. And Time Lapse Camera imagery from 30 minutes ago shows snow in the Tarfala Valley :) @stockholm-uni.bsky.social @bolincentre.bsky.social

Det är viktigare än någonsin att följa glaciärerna i detalj, menar glaciologen Nina Kirchner. F&F besökte henne på Tarfala forskningsstation och fick följa med till världens mest undersökta glaciär.

New in @oikosjournal.bsky.social! 📃

The study, led by Peter Hambäck at DEEP, explores how interactions between hosts and enemies shape biodiversity. Results show that bottom–up and top–down diversification don’t work the same way, and that parasitoids often adapt faster than their hosts.👇

Bottom–up and top–down diversification: asymmetric processes over space and time

Coevolution in trophic interactions is often considered as a major factor underlying diversification in interacting species. Most focus hitherto has however been on bottom–up processes where host-ass...

A study co-authored by Prof. Hambäck at DEEP shows that wild bee diversity drives apple seed set much more than managed honeybees. Functional diversity makes the biggest difference.

The takeaway: healthy, diverse wild pollinator communities are key for productive orchards. 🐝🍎
