Reconstructing climates of the past relies on a variety of evidence from a large number of
sites to capture the varied features of climate and the spatial heterogeneity of climate …

This paper provides an overview of stable isotope analysis (H, C, N, O, Si) of the macro-and
microscopic remains from aquatic organisms found in lake sediment records and their …

Relict woolly mammoth (Mammuthus primigenius) populations survived on several small
Beringian islands for thousands of years after mainland populations went extinct. Here we …

Predicting changes to methane cycling in Arctic lakes is of global concern in a warming
world but records constraining lake methane dynamics with past warming are rare. Here, we …

Methanotrophic bacteria play an important role oxidizing a significant fraction of methane
(CH 4) produced in lakes. Aerobic CH 4 oxidation depends mainly on lake CH 4 and oxygen …

We have known about the processes of methanogenesis and methanotrophy for over 100
years, since the days of Winogradsky, yet their contributions to the carbon cycle were …

This paper focusses on a conceptual overview of ways to address a comprehensive analysis
of ecosystem services (ES) in a country as large and heterogeneous as Russia. As a first …

Abstract The Late-Quaternary climate of Beringia remains unresolved despite the region's
role in modulating glacial-interglacial climate and as the likely conduit for human dispersal …

Continued warming of the Arctic may cause permafrost to thaw and speed the
decomposition of large stores of soil organic carbon (OC), thereby accentuating global …

Freshwater lakes are important sources of methane (CH 4) emissions, by organic matter
degradation under anaerobic conditions (methanogenesis). Previous studies suggest that …
