🐿️ ICYMI: In the #Yukon #permafrost, researchers found 700,000-year-old fossilized #dung from an #extinct ground #squirrel species.

These preserved #burrows contained ancient plant material, #bones, and the oldest #woollymammoth #DNA identified in #NorthAmerica, tracking how #prehistoric #ecosystems shifted over time.

[Science News] Rising global #temperatures are leading, in particular, to the melting of #permafrost . This permanently frozen soil stores a massive amount of organic #carbon (1,300 gigatons across the #arctic ) which rivers carry out to sea. However, a recent analysis of marine sediment cores shows that only 10% of this organic carbon is converted into gas by microorganisms, and thus contributes in turn to #globalwarming : https://scitechdaily.com/thawing-permafrost-is-releasing-carbon-but-something-unexpected-happens/

“Permafrost soils are particularly vulnerable to climate change. To assess and improve estimations of carbon (C) and nitrogen (N) budgets it is necessary to accurately map soil carbon and nitrogen in the permafrost region. In particular, soil organic carbon (SOC) stocks have been predicted and mapped by many studies from local to pan-Arctic scales. Several studies have been carried out at the Canadian Beaufort Sea coast, though no regional maps of terrestrial carbon stocks based on spatial modelling has been conducted yet. This study combines available field data from the Canadian Yukon coastal plain and uses it to map regional SOC and N stocks using the machine learning algorithm random forest and environmental variables based on remote sensing data. [The authors] developed models using the data for the entire region and separate models for the coastal mainland area and Qikiqtaruk Herschel Island. Each model was used to map SOC and N stocks for its respective area. [They] assessed the performance of the different random forest models by using crossvalidation. [They] further assessed model results using the Area of Applicability (AOA) method and the quantile regression forest approach, comparing the results and discussing their implications within the context of both methods. [They] explore[d] local differences in soil properties and how soil data distribution across the region affects the accuracy of the predictions of SOC and N stocks..."
