Species of the genus Ulva are common in anthropogenically disturbed areas and have been reported as the cause of green tides in many areas of the world.
In addition, they rank among the main marine groups used in a wide range of commercial applications.
By displaying few distinctive morphological characters, some taxonomical identifications are difficult and the genus is under a conundrum.
Our aims were to provide ecophysiological information about three Ulva species in response to abiotic factors and to evaluate the proposal of ecophysiological information and the chlorophyll-a fluorescence technique as auxiliary tool to resolve the long-standing taxonomic confusion.
We hypothesize that three cooccurring specimens (U.
fasciata Delile, U.
lactuca Linnaeus, and U.
rigida C.
Agardh) have different ecophysiological responses (as measured by the effective quantum yield of photosystem II by pulse amplitude modulated fluorometers) under manipulated conditions of temperature and nutrient concentration.
Ulva lactuca and U.
rigida showed different photosynthetic efficiencies related to temperature, whereas no difference was recorded for U.
fasciata individuals.
These results provide a reasonable explanation for the variability in spatial and temporal abundance of these species of Ulva on rocky shores.
We proposed the use of ecophysiological information by chlorophyll-a fluorescence as an auxiliary tool to corroborate the taxonomic distinction of Ulva species.
We reinforce the statement of U.
fasciata and U.
lactuca as distinct valid species.
