F1.3 Freeze-thaw rivers and streams
F1. Rivers and streams biome
Profile summary
Full profile at https://global-ecosystems.org/explore/groups/F1.3
Brief description
In cold climates at high latitudes or altitudes, the surfaces of both small streams and large rivers freeze in winter. In winter, the layer of surface ice reduces nutrient inputs and light penetration, limiting the productivity of these ecosystems and the diversity of their biota. In spring, meltwaters transport increased organic matter and nutrients, producing seasonal peaks in abundance of algae and phytoplankton. Animals, such as fish and beavers, tolerate near-freezing water temperatures, while a range of invertebrates and other vertebrates come to forage from spring to autumn.
Key features
Cold-climate streams with seasonally frozen surface water and variable melt flows and aquatic biota with cold-resistance and/or seasonal dormancy.
Overview of distribution
High latitudes and/or high mountains, especially boreal regions.
Map description
The distribution of freeze-thaw rivers and streams was mapped from the Global River Classification database (Ouellet Dallaire et al. 2018), including all reaches with with minimum temperature below 0°C..
Map code and version: F1.3.web.map v1.0.
