Importantly, in Fig. 5 of the paper, you will notice that even when species elevational ranges remain static over time, when x=0 on the x-axis, then the flowering time still shows a very significant signal of advances in 🌸 time

These regional variations in 🌸 time shifts are not randomly distributed in space, across 🇨🇳, with southwestern ⛰️ ranges being more likely to show delays in 🌸 time while southeastern ⛰️ ranges show advances in 🌸 time

Our University #UPJV just made it, this year, for the very 1st time, to the Shangai ranking of universities 🌎🌐
It turns out that the only academic subject appearing on the list of subject ranking is #Ecology 🌳🍁🪻🌱🦌🦔🦇🦉
We are pretty proud of us at #EDYSAN 😀

Why relying on the "equlilibrium assumption", i.e., biodiversity being in an equilibrium state w/ its environmental conditions, to model biodiversity trends in response to environmental changes?
➡️ We propose a paradigm shift: embracing the quasi-permanent non-equilibrium state 🤯

This "News feature" in Nature Water by Erica Gies is a must read 🧐 It points at the missing link between ecology & climatology, which, I dare to say, involves #microclimate #ecology ⬇️
"w/ more CO2 available, they [🌳🌲🌴🌵🌱🍀🌾🌺] may not need to open their stomata as much, releasing less water"

Since Robert Colwell's seminal study, many studies reported more evidence of elevational ranges shifts in 🏔, including evidence for #mountaintop #extirpation, the so-called #escalator to #extinction from Benjamin Freeman's excellent work published in 2018 in @pnas.org

This study was inspired & motivated by the work of Robert Colwell published in 2008 @science.org
It featured the 3 main risks of 🏔 species shifting their elevational ranges upslope in response to 🌡📈
1️⃣ Mountaintop extinction
2️⃣ Range-shift gaps
3️⃣ Lowland biotic attrition
