Colonization potential of the genus Ulva (Chlorophyta, Ulvales) in Comodoro Rivadavia Harbor (Chubut, Argentina)
Temporal and spatial changes in the coverage of five Ulva L. species (U. prolifera O.F. Müller, U. intestinalis L., U. hookeriana (Kützing) Hayden et al., U. compressa L. and U. linza L.) were analyzed on rocky substrata experimentally immersed in Comodoro Rivadavia Harbor (Argentina).

| description | Temporal and spatial changes in the coverage of five Ulva L. species (U. prolifera O.F. Müller, U. intestinalis L., U. hookeriana (Kützing) Hayden et al., U. compressa L. and U. linza L.) were analyzed on rocky substrata experimentally immersed in Comodoro Rivadavia Harbor (Argentina). Colonization was studied during an annual period at three levels: upper intertidal, middle intertidal and subtidal. Coverage was significantly higher in the middle intertidal and subtidal levels than in the upper intertidal level, where all species of Ulva were absent. Seasonal changes were also significant: coverage in summer and spring was significantly higher than in autumn and winter. Most species showed high spatial variability among replicates from the same level and season. Zonation patterns within the harbor differed from those observed in natural areas, probably due to low wave exposure and its interaction with herbivory and desiccation stress. Colonization patterns observed in this study indicate nichesegregation in closely related species of the genus Ulva. |

Se analizaron los cambios estacionales y espaciales en la cobertura de cinco especies de Ulva L. (U. prolifera O.F. Müller, U. intestinalis L., U. hookeriana (Kützing) Hayden et al., U. compressa L. y U. linza L.) sobre sustratos rocosos sumergidos experimentalmente en el puerto de Comodoro Rivadavia (Argentina). Se estudió la colonización durante un periodo anual en tres niveles: intermareal superior, intermareal medio y submareal. La cobertura fue significativamente mayor en los niveles intermareal medio y submareal que en el intermareal superior, en donde todas las especies de Ulva estuvieron ausentes. Los cambios estacionales también fueron significativos: la cobertura en verano y primavera fue significativamente mayor que en otoño e invierno. La mayoría de las especies presentaron una gran variabilidad espacial entre réplicas sumergidas en un mismo nivel y estación. Los patrones de zonación dentro del puerto difirieron de los observados en áreas naturales, probablemente a causa del bajo grado de exposición al oleaje y su interacción con procesos de herbivoría y desecación. Los patrones de colonización observados en este estudio indican segregación de nicho en especies estrechamente emparentadas del género Ulva.
