          Abstract

          Spartina es una gramínea peculiar por sus procesos de dispersión, sobrevivencia y evolución. Se desarrolla en ecosistemas de marismas, sobre suelos salinos en costas y en cuencas interiores. El género se encuentra distribuido principalmente en toda la costa Atlántica, en la costa Pacífica, únicamente en Baja California, Sinaloa y Oaxaca y en zonas interiores de Coahuila y San Luis Potosí. Todas las especies son poliploides, con una gran capacidad de hibridación y son usadas en la restauración de áreas con pérdida de suelo, convirtiéndose en muchos casos, en especies invasoras. Hasta la fecha, en México no se ha llevado a cabo un estudio exclusivo y exhaustivo sobre este género, por ello el objetivo del presente proyecto fue determinar el número de especies y distribución de Spartina en el país. En base a la revisión de ejemplares de herbario y bibliografía, se llevó a cabo la exploración de campo en las localidades donde se ha reportado la presencia de Spartina. En este estudio se reportan cuatro especies de las seis citadas para México: S. alterniflora, S. foliosa, S. patens y S. spartinae, siendo esta última la más ampliamente distribuida. Se ha señalado la presencia de S. gracilis en Jalisco, Michoacán y Chihuahua; y S. cynosouroides en Chihuahua y Tamaulipas, sin embargo, éstas no fueron localizadas en la exploración de campo ni en la revisión de herbario. No se encontró evidencia de especies introducidas en el país.

          Spartina is a distinctive grass genus because of its processes of dispersal, survival and evolution. It grows in ecosystems of tidal marshes, mudflats and saline basins. The genus is distributed mainly along the entire Atlantic coast, on the Pacific coast only in Baja California, Sinaloa and Oaxaca, and in inland areas of Coahuila and San Luis Potosi. All species are polyploid with a great capacity for hybridization. Frequently species of Spartina have been used in restoration of areas with soil loss; however in many cases they have become invasive weeds. To date, there has not been carried out an exclusive and comprehensive study of this genus in Mexico. The aim of this project was to determine the number of species of Spartina and their distribution in the country. Based on bibliographic and herbarium voucher information, field explorations were carried out in all Mexican localities where Spartina had been reported. Four out of the six species reported for Mexico were found: S. alterniflora, S. foliosa, S. patens, and S. spartinae, the latter being the most widely distributed. Reports of S. gracilis in Jalisco and S. cynosuroides in Chihuahua were noted; however, these species were not located in field explorations nor in herbarium collections. There is no evidence of any introduced species.

              How will warming affect the salt marsh foundation species Spartina patens and its ecological role?

              Foundation species structure environments and create refuge from environmental stress. In New England high salt marsh, the grass Spartina patens is a foundation species that reduces salinity, anoxia, desiccation, and thermal stresses through canopy shading and root proliferation. In a factorial S. patens-removal and warming field experiment, foundation species removal strongly impacted every aspect of the community, reiterating the important role of the foundation species S. patens in the high marsh. Given this central role, we hypothesized that facilitation by the foundation species would be even more important under warmer conditions by ameliorating more severe thermal stress. However, the ecological role of S. patens was unaffected by experimental warming, and, independent of the presence of the foundation species, warming had only weak effects on the salt marsh ecological community. Only the foundation species itself responded strongly to warming, by significantly increasing aboveground production in warmed plots. Apparently, amelioration of thermal stress is not as important for salt marsh ecosystem function as S. patens' moderation of salinity and desiccation stresses. From these experimental results, we anticipate that climate change-associated thermal stress will not greatly affect S. patens-dominated high marsh communities. In contrast, foundation species loss, an emergent conservation issue in Atlantic salt marshes, represents a critical threat to salt marsh ecosystem function.
