Terrestrial geosystems, ecosystems, and human systems in the fast-changing Arctic: research themes and connections to the Arctic Ocean

Autor: Warwick F. Vincent, Julia Boike, Victoria R. Buschman, Frédéric Bouchard, Scott Zolkos, Greg H. R. Henry, Brent B. Wolfe, João Canário

Publikováno v: Arctic Science, Vol 9, Iss 2, Pp 258-265 (2023)

In parallel to rapid sea-ice loss and other climate impacts in the Arctic Ocean, large-scale changes are now apparent in northern landscapes and associated ecosystems. Arctic communities are increasingly vulnerable to these changes, including effects

A review of open top chamber (OTC) performance across the ITEX Network

Publikováno v: Arctic Science, Vol 9, Iss 2, Pp 331-344 (2023)

Open top chambers (OTCs) were adopted as the recommended warming mechanism by the International Tundra Experiment network in the early 1990s. Since then, OTCs have been deployed across the globe. Hundreds of papers have reported the impacts of OTCs o

Experimental warming differentially affects vegetative and reproductive phenology of tundra plants

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-12 (2021)

It is unclear whether climate driven phenological shifts of tundra plants are consistent across the plant growing season. Here the authors analyse data from a network of field warming experiments in Arctic and alpine tundra, finding that warming diff

Equitable transform applied to phenology and temperature in a changing climate: Scaling to maintain individuality

Autor: Cassandra Elphinstone, Greg H. R. Henry

Publikováno v: Ecosphere, Vol 11, Iss 2, Pp n/a-n/a (2020)

Abstract We describe an equitable transform that can be used to estimate missing data points, determine systematic patterns in data, observe baseline changes, and detect different amplitudes in replicated sequences. It is applicable to short discrete

Increased Arctic climate extremes constrain expected higher plant reproductive success in a warmer climate

Autor: Greg H. R. Henry, Esther R. Frei, Zoe A. Panchen

Publikováno v: Arctic Science. 8:680-699

The low reproductive success of Arctic plants is predicted to increase as the climate warms. However, climate extremes add complexity to these predictions. In the extremely cold year of 2018, multiple Arctic trophic levels experienced reproductive fa

Vegetation influence and environmental controls on greenhouse gas fluxes from a drained thermokarst lake in the western Canadian Arctic

Autor: Greg H. R. Henry, June Skeeter, Elyn Humphreys, Andrée-Anne Laforce, Andreas Christen

Publikováno v: Biogeosciences, Vol 17, Pp 4421-4441 (2020)

Thermokarst features are widespread in ice-rich regions of the circumpolar Arctic. The rate of thermokarst lake formation and drainage is anticipated to accelerate as the climate warms. However, it is uncertain how these dynamic features impact the t
