Resumen
Abstract
Abstract Background and Aims The increase of extreme weather events due to climate change may alter ecosystem dynamics. In the tropics, little is known about how ecosystems and species will respond to droughts or foods. Identifying the most important biotic and abiotic factors in ecosystems at the local level is key to developing better forest management practices and understanding the efects of climate change on the fungal community. Methods We conducted a random sampling of adult individuals from several palm species across three adjacent ecosystems with diferent hydrological conditions, during rainy and dry seasons. Using next-generation sequencing, we identifed fungal communities and determined the infuence of soil physicochemical properties, as well as host and seasonal variables, on the relative abundance of the root- and rhizosphereassociated fungal communities. Results The composition of the fungal communities was similar between the seasonally fooded forest and the terra-frme forest, while the palm swamp diverged due to diferences in soil physicochemical properties. Seasonal analyses revealed signifcant diferences in the relative abundance of several taxa, mainly associated with the seasonally fooded forest. However, no infuence of palm species on fungal abundance was detected at any taxonomic level. Conclusion This study highlights the importance of studying ecosystems at the local scale and considering ecosystem dynamics into the study of fungal communities and other microorganisms. Such an approach is crucial for improving predictions under climate change scenarios and understanding the consequences of altering these dynamics in vulnerable, often understudied ecosystems.
