AB The identification of relevant scales of variation is a necessary prerequisite before explanatory models can be proposed and tested. In this study spatial and temporal patterns of biomass distribution were assessed for two Ulva morphologies in twoIrish estuaries heavily affected by green tides (wet biomass>1 kg m−2 during the peak bloom). Moreover, usinggenetic markers, the species composition of these green tides was assessed. Results revealed that these bloomswere multi-specific, with Ulva prolifera, U. compressa and U.rigida the most frequent species. The species U.prolifera and U. compressa usually showed a tubular morphology, while U. rigida was mainly laminar. A seasonalsuccession common to both estuaries was also identified, with the bloom dominated by tubular species duringspring and early summer, and co-dominated by tubular and laminar morphologies during late summer andautumn. Moreover, tubular and laminar morphologies exhibited different distribution patterns, with tubularmorphologies varying at bigger spatial scales and higher biomass than the laminar. As tubular and laminarmorphologies exhibited different distribution patterns, varying tubular morphologies along bigger spatial scaleswith higher biomass levels than the laminar. Considering that tubular morphologies were usually anchored tothe sediment, while laminar Ulva were usually observed free-floating, these differences could explain a differentialinfluence by water motion. An important annual and decadal variability in biomass levels of Ulva wasobserved, in the case of the Tolka estuary a noticeable increase over the last two decades. These findings shouldbe considered for the development of management and monitoring strategies since the different habitat of laminarand tubular morphologies (anchored vs. free-floating) may play an important role in the balance of nutrientsand biomass in the estuary, or determine the response to pollutant exposure.
