South West Atlantic salt marshes as model systems for community and ecosystem ecology
Just as some species are used as model systems in organismal biology (e.g., physiology, genetics), many ecosystems are commonly used as model systems in ecology. Salt marshes, for instance, are great models to perform manipulative field experiments, and thus, were historically used to understand the drivers of community and ecosystem function. Decades of experimental work, indeed, made a strong contribution to community ecology as a discipline, but most of the emerged hypotheses and models were grounded in a few sites. When studies from new sites came onboard, looking to enlarge generalities, their results challenged the prevailing ideas. Here, we review more than 25 years of intense experimentation in South West Atlantic salt marshes, which helped not only to increase the knowledge about salt marsh functioning, but also to expand this knowledge beyond salt marshes helping to refine community and ecosystem function theory. We show that results coming from SW Atlantic marshes significantly contribute to understand 1) the separate and interactive effect of biotic and abiotic stress for species distribution and even for ecosystem stability, 2) the integrated role of species that can function as ecosystem engineers and as consumers, 3) the balance between stochastic and deterministic forces as drivers of community structure and 4) the regulation of cross-ecosystem fluxes. Nevertheless, we believe SW Atlantic salt marshes still have a lot more to offer, not only as conceptual models that help satisfy our intellectual curiosity, but also as key ecosystems that provide valuable benefits to our societies.

El uso de ciertas especies como sistemas modelo es común en algunas ramas de la biología (e.g., fisiología, biología molecular, genética). De manera similar, existen ecosistemas muy usados como modelo en ecología. Las marismas, por ejemplo, son sistemas relativamente simples, lo que los hace ideales para realizar experimentos manipulativos de campo. Por ello, son muy utilizadas para entender los determinantes de la estructura y el funcionamiento de comunidades y ecosistemas. Históricamente, la influencia de trabajos realizados en marismas tuvo gran impacto sobre el desarrollo de la ecología de comunidades como disciplina. Sin embargo, la mayor parte de los trabajos que dieron lugar a teorías y modelos generales provienen de unos pocos lugares, por lo que muchas veces, al querer ponerlos a prueba en otros sitios geográficos, los resultados obtenidos parecen no ajustarse a las predicciones. En este artículo hacemos una revisión de algunos trabajos, realizados en las marismas del sudoeste Atlántico durante más de 25 años, que ayudaron no sólo a que entendamos mejor el funcionamiento de las marismas en sí, sino también a extender el conocimiento más allá de estos sistemas en particular. En esta revisión mostramos cómo los resultados obtenidos en las marismas del SO Atlántico contribuyeron al entendimiento de 1) los efectos aislados e interactivos de factores bióticos y abióticos sobre la distribución de especies y hasta la estabilidad de los ecosistemas, 2) el rol integral de especies que pueden actuar simultáneamente como ingenieras y como consumidoras, 3) el balance entre procesos neutrales y determinísticos como reguladores de la estructura comunitaria, y 4) la regulación de los flujos entre ecosistemas. Sin embargo, estas marismas tienen mucho más para ofrecer, no sólo como modelos conceptuales que ayudan a calmar nuestra curiosidad intelectual, sino como ecosistemas clave en la provisión de servicios ecosistémicos.
