摘要

Vertebrate carrion serves as a focal point for necrobiome communities involved in decomposition processes that are responsible for consuming, metabolising, assimilating, and dispersing carrion-derived resources. While previous research has mainly examined tropical and temperate regions, polar regions, particularly Antarctica, remain understudied. This study addresses this gap by exploring microbial communities and soil chemical profiles linked to penguin carrion. This study investigates the microbial communities and soil chemistry associated with penguin carrion in this extreme environment. Our findings revealed a positive correlation (r = + 1) among fungal communities in the soil surrounding penguin carrion, while a negative correlation (r = − 1) was observed between some species of fungi and bacteria. Meanwhile, correlation analysis of soil chemistry showed variability related to penguin species, decomposition stages, and sampling locations. These results indicate that the necrobiome’s correlation is shaped by its role in decomposition and adaptation to the region’s unique climate, enhancing our understanding of carrion decomposition in Antarctica.
