Fungal communities refer to the diverse populations of fungi that exist in various environments, such as soil, water, and plants. These communities play important roles in ecosystem processes, including decomposition, nutrient cycling, and plant disease suppression. Research in fungal communities involves studying the diversity, interactions, and functions of different fungal species in different habitats, as well as the impact of environmental factors and human activities on fungal diversity and composition. This research area is critical for understanding the ecological and evolutionary dynamics of fungi and their roles in maintaining ecosystem health and functioning.
