RESUMO:

Soil carbon dynamics have become an increasingly relevant to human well-being in the context of global climate change. Changes in temperature, humidity, seasonality, and other environmental factors resulting from land-use change affect invertebrates in modified environments and their interactions with soil carbon. This issue is particularly important in tropical regions, which harbour the greatest invertebrate biodiversity and are experiencing extensive land-use change driven by human activities.  From this perspective, the scarcity of information regarding the potential relationships between soil invertebrate fauna and carbon dynamics in the tropical region represents a significant gap in ecological knowledge. Therefore, conducting a review on this subject is essential, considering that the tropics harbor a substantial portion of invertebrate biodiversity and are undergoing intensive land-use changes driven by anthropogenic activities. In this context, a systematic review was carried out using studies conducted in tropical regions that investigated soil carbon dynamics and soil invertebrates. The Scopus and Web of Science databases were utilized for the search, and following the filtering process, metrics from 55 articles were extracted. We found a higher proportion of studies (36.4%) conducted in the Neotropical region, with Brazil and China being the most frequently investigated countries. The least investigated region was Australasia, accounting for only 7.3% of the studies. A large proportion of the studies focused on soil organic carbon and its fractions, including both labile components that are readily transformed by soil fauna activity and more stable carbon fractions associated with soil organic matter. Metrics such as tree carbon stocks, soil respiration, and easily oxidizable carbon, related to soil invertebrate fauna, have been increasingly investigated in recent years. Regarding soil fauna, the main taxonomic groups studied were Arthropoda, Annelida, and Nematoda, which tended to show positive relationships with carbon metrics. Understanding soil carbon dynamics and their relationships with soil invertebrate fauna is essential for elucidating how these interactions influence carbon stocks and emissions, thereby affecting ecosystem services in both natural and human-modified environments.
