Borealization of tundra ecosystems with climate and land-use change
Open AccessMariana Verdonen, Isabel C Barrio et al.ARTICLEEnvironmental Research Letters2025
As the colder regions of the planet warm, species are moving northward and upward from the boreal forest to the tundra biome, a process that has been referred to as borealization. Here, we examine the diverse uses of the term borealization and propose the concept of ‘tundra borealization’ for terrestrial environments to specifically describe shifts and increases in abundance of boreal species into the tundra. We summarize the evidence to date for…
Systemic analysis of a developing plant community on the island of Surtsey
Open AccessHannah Schrenk, Borgþór Magnússon et al.ARTICLEConservation Ecology2022Cited by: 1
Based on our recently developed method to quantify Gunderson and Holling's adaptive cycle, we provide a holistic analysis of a vascular plant community on the volcanic island of Surtsey between 2000 and 2018. We identify one complete adaptive cycle during the study period, which reflects the system's transition from a classic pioneer to a grassland community. Our results support the hypothesis that nutrients brought to the island by breeding gull…
Using research networks to create the comprehensive datasets needed to assess nutrient availability as a key determinant of terrestrial carbon cycling
Open AccessSara Vicca, Benjamin D Stocker et al.ARTICLEEnvironmental Research Letters2018
A wide range of research shows that nutrient availability strongly influences terrestrial carbon (C) cycling and shapes ecosystem responses to environmental changes and hence terrestrial feedbacks to climate. Nonetheless, our understanding of nutrient controls remains far from complete and poorly quantified, at least partly due to a lack of informative, comparable, and accessible datasets at regional-to-global scales. A growing research infrastru…
