Compositional shifts of alpine plant communities across the high Andes

Abstract: AimClimate change is transforming mountain summit plant communities worldwide, but we know little about such changes in the High Andes. Understanding large‐scale patterns of vegetation changes across the Andes, and the factors driving these changes, is fundamental to predicting the effects of global warming. We assessed trends in vegetation cover, species richness (SR) and community‐level thermal niches (CTN) and tested whether they are explained by summits' climatic conditions and soil temperature trends.Loca… Show more

“…As a result, many mountain summits across the globe are currently gaining, rather than losing, species over time (Wipf et al 2013, Carilla et al 2018, Steinbauer et al 2018, Cuesta et al 2023). This overall long-term increase in species richness is linked to climate change, leading to a shift in the upper range limit of many species that track the shifting isotherms (Lenoir and Svenning 2015).…”

“…In addition, high-Andean wetlands are important in climate and biogeochemical cycles regulation ( Mitsch and Gosselink, 2015 ). Climate change is already impacting ecosystems worldwide, and it is expected to continue or accelerate its impact in the future, representing a major threat to high mountain ecosystems worldwide ( Pauli and Halloy, 2019 ; Cuesta et al., 2023 ). Andean wetland ecosystem dynamics are mainly regulated by temperature and precipitation, a factor that places them among the most sensitive and vulnerable ecosystems facing global climate change ( Dangles et al., 2017 ; Cuesta et al., 2019 ).…”

“…Las especies que ocupan rangos de elevación relativamente estrechos en los ecosistemas de montaña son altamente sensibles al cambio climático (Sklenar & Jorgensen, 1999) y se espera que, con el tiempo, estas especies se vean obligadas a modificar su distribución dependiendo de sus preferencias ecológicas (Nagy & Grabherr, 2009;Corlett & Westcott, 2013;Winkler et al, 2016). Este proceso por el cual las comunidades cambian su distribución, debido a los cambios de la temperatura, llamado "termofiliazion", se observó en los Andes para árboles de bosques montanos (Fabrique et al, 2018) y para la vegetación altoandina (Cuesta et al, 2023). Esto genera que, ante el rápido cambio climático, adquiere cada vez mayor importancia identificar el conjunto de condiciones ambientales asociadas con grandes áreas y cubiertas forestales, para definir áreas clave para la conservación de estas especies en las condiciones futuras proyectadas.…”
