摘要

The degree to which environmental and spatial processes influence functional guilds in spatially structured coastal lagoons remains underexplored, yet this knowledge is critical for improving transferability of ecological models across different locations. We aimed to explore the response of estuarine use (EUFG) and trophic functional guilds (TFG) to environmental and spatial processes in a Neotropical coastal lagoon in southeastern Brazil. Analyses showed that EUFG were slightly more responsive to environmental and spatial processes than TFG, with 38% of their variation primarily influenced by salinity and spatial variables. In contrast, TFG showed a weaker response, with 30% of variation explained driven by depth, salinity, and transparency. The proportion of explained variation in both guild types, although moderate, suggests that additional factors, such as unmeasured environmental variables or biotic interactions, likely play a significant role in driving community assembly. Our results highlight the context-dependent nature of functional guild classification, as different guilds capture distinct ecological signals depending on the ecosystem and the proxies used to represent ecological processes. Thus, the selection of appropriate proxies is crucial, as is identifying ecologically equivalent windows, which could enhance the transferability of findings between coastal lagoons and other spatially structured ecosystems.
