The marine macroalgal flora of Brier Island, Nova Scotia, Canada / by D. J. Garbary ... [et al.]. : Fs97-6/3288E-PDF

"From May to October 2017, seaweeds were identified in the field and laboratory from 20 sites around Brier Island, Nova Scotia. While most sites were intertidal rocky shores, there was one small salt marsh and one eelgrass bed included in the study and some subtidal sampling via SCUBA and snorkeling. The Brier Island seaweeds were made up of 152 species and varieties of which 62 were red algae, 44 were green algae, 44 were brown algae, and two species were xanthophytes. Four species were new records for eastern Canada: Cladophora liniformis, Colaconema bonnemaisoniae, C. endophytica, and Elachista stellaris, all of which were previously recorded from New England. The flora included eight non-native species of which Colpomenia peregrine and Bonnemaisonia hamifera (both gametophytic and tetrasporophytic stages) were abundant at two or more sites. The invasive Codium fragile subsp. fragile occurred as a single drift specimen. Brier Island has greater species richness than similarly sized areas in the Canadian Maritimes, with relatively higher numbers of red algae and a Cheney floristic index of 2.4"--Abstract.
