Vegetation carbon stocks in Spain declined 12% between 2017 and 2024, a loss of 150 million tonnes carbon. 2026 fires further intensify decline in carbon stored in woody biomass. We risk turning a sink into a source of emissions—transforming a solution into a problem. eartharxiv.org/repository/v...
@plosbiology.org - The integration of biogeography and ecology has been limited. The emergence of new methods and high-quality ecological network data at biogeographical scales promote deeper integration of biogeography and ecology. @mncn-csic.bsky.social journals.plos.org/plosbiology/...
Biotic interactions biogeography: A framework for understanding how species interactions shape biodiversity patterns across scalesBiogeography and ecology have long developed in parallel.

Some argue protected areas in fire-prone landscapes can undermine forest carbon (fuel build-up → higher fire risk). This paper shows Spanish protected areas consistently outperform comparable unprotected lands, strongest in National Parks. iopscience.iop.org/article/10.1...
