The way we are, function and change: The information, mass and energy theory

In this paper @joseppenuelas proposes the IME (information, mass, energy) theory, that integrates the 5 laws of life by determining the relationships among information, mass and energy through time and after disturbances ✍️

Hydrology Paper of the Day @sigdelshalik on modelling the biogeography of fir and birch trees under climate change scenarios: fir trees will move upslope faster than birch trees; competition and succession; spatial analyses via the Programita software; and effects of scale.

The Himalayan tree landscape is shifting—and so are its ecosystems At high elevations, fir trees are outcompeting once-dominant birches amid warmer, drier conditions

Anthromes and forest carbon responses to global change Forest ecosystems absorb and store about 25% of global carbon dioxide emissions annually and are increasingly shaped by human land use and management. Climate change interacts with land use and fores...

nph.onlinelibrary.wiley.com/doi/10.1002/... In 2023, I was part of the symposium “Anthromes, CO2, and Terrestrial Carbon: From the deep past to net-zero”, after which J. Aaron Hogan masterfully led an interesting analysis on how the concept of Anthromes can be used to understand global land carbon.
