A new study by François Keck et al. reveals that human pressures reshape #biodiversity, but don’t always lead to global homogenization. Instead, impacts vary by scale, ecosystem, and type of disturbance. 🌍🧪

-> Most invasions lead to neutral community changes, can be beneficial for local communities, by increases in #diversity and in communities stability. Future species invasions may have far-reaching consequences for entire communities and ecosystems, but these consequences need not always be negative

Samuel Dijoux @dijouxsam.bsky.social · Jan 13

-> 2) #Invasivespecies are not necessarily bad for local communities!
Our findings challenges the conventional wisdom that #invasivespecies are usually harmful and lead to the #extinctions and #collapses of local communities.

Samuel Dijoux @dijouxsam.bsky.social · Jan 13

The trophic position of #invasivespecies (as #predator or #prey), the #sizes of local and invasive species & the abiotic conditions play a key role for invasion success
-> 1) #Warming and #eutrophication are likely to accelerate invasions of smaller species!

Early 2024, my 2nd paper was out on the key roles of species body sizes and trophic positions to predict the outcomes of #invasivespecies in communities under gradients of #temperature and nutrients levels. A cool study with N. Pichon, A. Sentis & @davidboukal.bsky.social

NEW: 2024 has just been confirmed as the warmest year on record, and the first to breach the 1.5C threshold.

We used a ridgeline (Joy Division inspired) chart to visualise daily temperature anomalies since 1940.

2024 clearly stands out with 100% of its days above 1.3C and 75% above 1.5C.

Ridgeline chart showing the distribution of global daily air temperature differences from the pre-industrial reference period (1850-1900), for every year between 1940 and 2024. Each individual year resembles a hill, shaded in a darker shade of red and further to the right for warmer years. The trend is clearly towards warmer years, with 2024 standing out as first year above 1.5C.
