Description

Aims
Subtropical wetlands provide critical biodiversity and ecosystem services, yet increasingly face agricultural pressures. Our study assessed how disturbance type, intensity, and recovery time influence vegetation dynamics in wetlands, employing robust methodological approaches to characterize ecological responses.

Location
Malezales wetlands, Corrientes, Argentina.

Methods
We used a chronosequence approach based on vegetation surveys of 612 plots (1 m2 each) distributed across 43 paddocks with contrasting disturbance histories. Vegetation cover was assessed using the Braun-Blanquet phytosociological method. We evaluated three types of anthropogenic disturbances commonly associated with agricultural land use in subtropical wetlands: drainage, plowing, and rice cultivation. Multivariate analyses, specifically canonical correspondence analysis (CCA), were applied to quantify how disturbance intensity and recovery time influence plant community composition and functional group responses.
