| contents | Colonization potential of the genus Ulva (Chlorophyta, Ulvales) in Comodoro Rivadavia Harbor (Chubut, Argentina) Alicia Rico Paola Lanas Juan López-Gappa Ciencias de la Tierra Ulva Patagonia Argentina Chlorophyta Comodoro Rivadavia Harbor 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 immersedin 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 upperintertidal level, where all species of Ulva were absent. Seasonal changes were also significant: coverage in summer and springwas significantly higher than in autumn and winter. Most species showed high spatial variability among replicates from the samelevel and season. Zonation patterns within the harbor differed from those observed in natural areas, probably due to low waveexposure and its interaction with herbivory and desiccation stress. Colonization patterns observed in this study indicate nichesegregation in closely related species of the genus Ulva. 2005 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48031411 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.4 Vol.31 |
