AbstractResponses of ecological communities to perturbations are inherently variable because responses of their constituent populations also vary. Species within a single community may show combinations of no response, positive responses, and negative responses to any given perturbation often canceling each other out resulting in small or no signal that the community level. Here we explore the impacts of warming and loss of the dominant species on alpine ecosystems in a global study.

Introduction Human-induced global change has accelerated a biodiversity change worldwide (Wardle et al. 2011, Díaz and Malhi 2022). However, we know little about how global change affects soil microbes (Shangguan et al. 2023) and how it will affect many ecosystem functions on the land surface (i.e. the horizontal spatial dimension) (Jing et al. 2015, Wall et al. 2015, Delgado-Baquerizo et al. 2020, Berlinches de Gea et al. 2023).

1 INTRODUCTION Ecosystems and communities are shaped by many interacting physical, chemical, and biological processes, but the phenomenon of cold-air pooling is frequently overlooked.

AbstractHistorically high anthropogenic nitrogen (N) deposition enhanced the global terrestrial carbon (C) sink that has partially offset anthropogenic CO2 emissions. This was driven by the suppression of microbial activity associated with the breakdown of biochemically recalcitrant soil organic matter (SOM), which resulted in the consequential accumulation of soil C.
