RT Journal Article T1 Differential Effects of Increasing Salinity on Germination and Seedling Growth of Native and Exotic Invasive Cordgrasses A1 Infante Izquierdo, María Dolores A1 Castillo Segura, Jesus Manuel A1 Grewell, Brenda J. A1 Jiménez Nieva, Francisco Javier A1 Muñoz Rodríguez, Adolfo Francisco AB Soil salinity is a key environmental factor influencing germination and seedlingestablishment in salt marshes. Global warming and sea level rise are changing estuarine salinity, andmay modify the colonization ability of halophytes. We evaluated the e ects of increasing salinityon germination and seedling growth of native Spartina maritima and invasive S. densiflora fromwetlands of the Odiel-Tinto Estuary. Responses were assessed following salinity exposure fromfresh water to hypersaline conditions and germination recovery of non-germinated seeds whentransferred to fresh water. The germination of both species was inhibited and delayed at high salinities,while pre-exposure to salinity accelerated the speed of germination in recovery assays compared tonon-pre-exposed seeds. S. densiflora was more tolerant of salinity at germination than S. maritima.S. densiflora was able to germinate at hypersalinity and its germination percentage decreased at highersalinities compared to S. maritima. In contrast, S. maritima showed higher salinity tolerance in relationto seedling growth. Contrasting results were observed with di erences in the tidal elevation ofpopulations. Our results suggest S. maritima is a specialist species with respect to salinity, whileS. densiflora is a generalist capable of germination of growth under suboptimal conditions. InvasiveS. densiflora has greater capacity than native S. maritima to establish from seed with continued climatechange and sea level rise.
