Temperature and Humidity Effects on Soil Respiration in the Thermokarst Depression Zone

Abstract

Galeano Sprent*

Temperature and humidity are critical environmental factors influencing soil respiration rates, particularly in thermokarst depression zones. Understanding these effects is essential for predicting carbon dynamics in permafrost-affected regions. This article reviews current research on how temperature and humidity variations influence soil respiration in thermokarst depressions, highlighting the mechanisms involved and the implications for climate change. Key findings suggest that higher temperatures generally increase microbial activity and carbon release from soils, while humidity moderates these effects by influencing substrate availability and microbial physiology. Moreover, the unique characteristics of thermokarst depressions, such as increased waterlogging and organic matter accumulation, further complicate the relationships between temperature, humidity, and soil respiration. Future research directions emphasize the need for integrated studies that consider both abiotic and biotic factors to improve predictive models of soil carbon dynamics in these vulnerable ecosystems.
