Our Virtual Issue compiling the Editor's Choices of 2025 has been published!

Editor's choices are papers that engage ecologists across general ecology while advancing understanding of ecological mechanisms, processes, and patterns — precisely Oikos goals.

I’m launching a blog series for @oikosjournal.bsky.social , “View from the Editor’s Desk” - the first post is now live.

These pieces reflect my personal perspectives on different aspects of the publication system and not official journal policy.

A blue tit nestling is held between a thumb and fingers during fieldwork. The chick’s fluffy grey head and yellow breast are visible, with a soft-focus outdoor background.

Our paper is Editor's Choice for the February Issue of @oikosjournal.bsky.social 🐣🐤🐥🎉

Using 10 years of data on great & blue tits, we show paler yellow plumage might be linked to urban-specific selection patterns.

A 27-year, continent-wide study of fig wasps by Souza et al. (2025) shows that communities linked to Neotropical fig trees change dramatically across space, with high species turnover driven by host specialization, competition, and local adaptation.

One of the graphics of the paper on Anthyllis cytisoides resprouiting after drought, showing model predictions and observations of the data analysed in 2022 and 2023; fire occurred in 2021. For flowering and fruiting, the negative effects of drought are stronger on unburned plants (A and C). Burned plants produced nearly four times more flowers than unburned plants (B), and had a higher seed set and heavier seeds than unburned plants in both years (D and E).

Gamblin et al. (2025) highlight polar bears as key providers of food in the Arctic, showing that the carrion from their seal kills fuels a network of scavengers and transfers large amounts of energy across marine and terrestrial ecosystems.
