“…With a mean coverage of ~60% per trait, this database will be a solid tool for a variety of biological research and related fields, including marine conservation, nature-based solutions, and aquaculture. For example, traits can be used to monitor community and ecosystem changes (McGill et al, 2006;Vélez-Rubio et al, 2021) or to identify conservation priorities (Albouy Cardeccia et al, 2018;Esmaeili et al, 2022). In addition, they can be incorporated into predictive modelling to assess eco-evolutionary consequences of climate change (Schleuning et al, 2020), can contribute to predicting the invasiveness of species (Nyberg and Wallentinus, 2005;Quell et al 2021), be used in research aiming to better understand the driving forces of evolutionary trait history (Heesch et al, 2021), or the mechanisms of community assembly (Weiss and Ray, 2019), and can even help to assess ecosystem services vulnerability Stevenson, 2014).…”

“…In the 1980s, Littler & Littler (1980; used the adaptive value of morphological traits to categorise algal species into morpho-functional groups, which cluster species with similar ecological functioning. As the concept of morpho-functional groups is relatively easy to apply and can limit processing time and associated costs, it has been frequently applied in seaweed ecology (Veiga et al, 2013;Vélez-Rubio et al, 2021). As a result, multiple variations of the original six morpho-functional groups have been developed and applied in a wide range of contexts.…”

Abstract. The analysis of biological and ecological traits has a long history in evolutionary and ecological research. However, trait data are often scattered and standardised terminology that transcends taxonomic and biogeographical context are generally missing. As part of the development of a global trait database of marine species, we collated trait information for European seaweeds and structured the data within the standardised framework of the World Register of Marine Species (WoRMS). We collected 45,175 records for 21 biologically and ecologically relevant traits of seaweeds. This resulted in a trait database for 1,745 European seaweed species of which more than half (56 %) of the records were documented at the species level, while the remaining 44 % was documented at a higher taxonomic level and subsequently inherited at lower levels. The trait database for European seaweeds will serve as a foundation for future research on diversity and evolution of seaweeds, and their responses to global changes. The data will contribute to developing detailed trait-based ecosystem models, and will be an important tool to inform marine conservation policies. The data is publicly accessible through the AlgaeTraits portal, algaetraits.org, doi: https://doi.org/10.14284/574, (AlgaeTraits, 2022).

“…Small portions of each thallus were rinsed with seawater and preserved in silica gel. The remainder of each individual was used to observe and record morphological characters, and was later pressed in a herbarium sheet and deposited in the Herbarium BBB of Universidad Nacional del Sur, Argentina (herbarium acronyms follow Thiers, 2021). The list of the 45 specimens used in this study is provided in Table S1.…”

“…At the coasts of South America, between 23° S and 34° S, only one species of Scytosiphon has been recorded, S. lomentaria (Oliveira Filho 1977, Steigleder et al, 2019, Vélez‐Rubio et al, 2021), whereas above 34° S, the species reported are S. lomentaria , S. dotyi (Boraso, 2013; Croce et al, 2015), and S. complanatus (= Planosiphon complanatus ; Asensi & Küpper, 2012). A tiny Scytosiphon species from the Falkland Islands was described by Skottsberg (1907) and named S. crispus , but there are no records of its presence in the continent.…”

Scytosiphon is a common intertidal genus widely distributed on temperate coasts worldwide. Recently, eight species have been delimited with molecular tools. Although S. lomentaria is the only species that predominates in the macroalgal literature of the Southwestern Atlantic Ocean (SwAO), unpublished molecular data obtained for a population study of S. lomentaria revealed hidden species diversity of Scytosiphon among the individuals collected from four localities at the SwAO. The aim of this study was to revise the identity and phylogenetic relationships of Scytosiphon from temperate coasts of the SwAO using DNA data. Thalli were collected from the Argentinean coast between 39° S and 43° S, from which cox1 and rbcL gene sequences were obtained. Phylogenies and haplotype networks were inferred and morphology of gametophytes was studied. Four species were recognized, S. lomentaria, S. promiscuus, S. shibazakiorum, and one species that belongs to a complex of species known as "Scytosiphon Atlantic complex." This complex was known to occur only in the North Atlantic, however, the results found in this study revealed that it has an extended distribution range that includes the southern hemisphere, where its populations have high genetic diversity and unique haplotypes. The morphological differences among the four species were subtle; denoting that previous Scytosiphon records from the SwAO attributed to the renowned S. lomentaria could represent different species. In addition, sex ratio and genome-wide single nucleotide polymorphisms (SNPs) analyses were done for populations of S. promiscuus presumably introduced to the SwAO, and the results indicated that they included female-dominant parthenogenetic populations, which were probably introduced from Japan.

“…Overall, a growing number of studies are documenting rocky intertidal biogeographic patterns and the underlying drivers across the globe. Examples include those done on the NE (Blanchette et al, 2008;Fenberg et al, 2015), SE (Broitman et al, 2001;Ibanez-Erquiaga et al, 2018), SW (Poloczanska et al, 2011;Schiel et al, 2019), and NW (Ishida et al, 2021;Hu and Dong, 2022) Pacific coasts, the Indian Ocean coast (Tsang et al, 2012), the Arctic (Thyrring et al, 2021) and Antarctic (Griffiths and Waller, 2016) coasts, and the NE (Hawkins et al, 2019;Pereira et al, 2022), SE (Bustamante et al, 1997;Hill and McQuaid, 2008), SW (Palomo et al, 2019;Veĺez-Rubio et al, 2021), and NW (Adey and Hayek, 2005) Atlantic coasts. This list of studies is naturally not exhaustive, as related studies are cited in those articles.…”

Biogeographic studies aim to understand species distributions and are becoming increasingly relevant to establish baselines to monitor ecological change. The NW Atlantic coast hosts a cold-temperate biota, although knowledge about its biogeography is patchy. This study documents for the first time biogeographic variation at mid-to-high intertidal elevations in wave-exposed rocky intertidal habitats along the open Atlantic coast of Nova Scotia (Canada), a hydrographically distinct subregion of this cold-temperate region. For this goal, we measured the summer abundance of algae and invertebrates at the same nine locations over four consecutive years (2014 to 2017) spanning 415 km of coastline, which allowed us to examine latitudinal and interannual patterns. In addition, we looked for mensurative evidence on possible drivers underlying these patterns, focusing on sea surface temperature, daily maximum and minimum temperature (which often happen at low tides at thus differ from sea surface temperature), pelagic food supply for intertidal filter-feeders (phytoplankton abundance and particulate organic carbon), drift sea ice during the cold season (which can cause intertidal disturbance), and species associations. Our field surveys revealed that northern locations can be severely disturbed by ice scour when drift ice is abundant and, while biological recolonization occurs over the years, it differs in pace among locations. Southern locations, instead, did not experience ice scour during our study and, thus, generally exhibited a higher species richness and abundance than northern locations. Multivariate analyses indicated that the aforementioned expressions of temperature and pelagic food supply explained together 32–55% of the variation in alongshore biogeographic pattern, depending on the year. Species association analyses suggest that algal foundation species (generally more abundant at southern locations) contribute to increase location-wise species richness. Mensurative evidence for bottom-up forcing in seaweed–herbivore and filter-feeder–predator systems differed greatly among years. Overall, in addition to its inherent value to advance NW Atlantic intertidal biogeography, our species distribution database should be valuable to assess ecological change decades into the future as climate change and other anthropogenic influences unfold.
