🦉🐦🦢Exploring species richness change across scales! We decomposed it into colonization, extinction, and persistence, and unveils patterns from local to national scales. Thanks to the guidance of @R_you_cereal, we connect theory with ecological processes https://t.co/MaBtDjbSJr

Temporal biodiversity change involves colonization, extinction, and recurrence of species. These processes vary with spatial grain (i.e. the area at which biodiversity is assessed), but there is...

Shifts in Danish bird communities over the past 40 years are linked to climate & land-use change. Using volunteer bird observations, we found that local species richness fell slightly, abundance dropped 7% per decade, and composition changed rapidly 🐦‍⬛ https://t.co/2TJX6lnFnr

Does conservation work? Our paper by @rewild shows that it does: a global analysis of 665 trials (incl. several by @RSPBScience) found that conservation improved the state of biodiversity or slowed declines in two-thirds of cases @BirdLife_Sci https://t.co/DskyzkYffQ

Very nice opinion paper in @Trends_Ecol_Evo by @callaghanct, Luca Santini, @BecksSpake , and @BowlerDBear showing that most abundance estimates are relative estimates. They argue for more attempts at estimating absolute abundance

Assessment of the rate of species loss, which we also label extinction, is an urgent task. However, the rate depends on spatial grain (average area A ) over which it is assessed—local species loss...

⚠️ Last but not least: out of the 253 species with increasing abundance, 96% show a decrease in recruitment rate as the main process, raising concerns about eventual declines, even for seemingly thriving species 🧵👇

We decomposed this temporal dynamic into processes of recruitment and loss, and show which of these is the strongest in driving the acceleration. Increase in loss is dominant in the Midwest and California, while it is the decrease in recruitment in the Mid-Atlantic region 🧵👇
