Revision of Herbarium Specimens of Freshwater Enteromorpha-Like Ulva (Ulvaceae, Chlorophyta) Collected from Central Europe During the Years 1849–1959
Phytotaxa 218 (1): 001–029 ISSN 1179-3155 (print edition) www.mapress.com/phytotaxa/ PHYTOTAXA Copyright © 2015 Magnolia Press Article ISSN 1179-3163 (online edition) http://dx.doi.org/10.11646/phytotaxa.218.1.1 Revision of herbarium specimens of freshwater Enteromorpha-like Ulva (Ulvaceae, Chlorophyta) collected from Central Europe during the years 849–959 ANDRZEJ S. RYBAK Department of Hydrobiology, Institute of Environmental Biology, Faculty of Biology, Adam Mickiewicz University, Umultowska 89, PL61 – 614 Poznań, Poland. [email protected] Abstract This paper presents results concerning the taxonomic revision of Ulva taxa originating from herbarium specimens dating back to 1849–1959. A staining and softening mixture was applied to allow a detailed morphometric analysis of thalli and cells and to detect many morphological details. The study focused on individuals collected exclusively from inland water ecosystems (having no contact with sea water). Detailed analysis concerned the following items: structures of thalli and cells, number of pyrenoids per cell, configuration of cells inside the thallus, occurrence or not of branching thallus, shapes of apical cells, and shape of chromatophores. The objective of the study was to confirm the initial identifications of specimens of Ulva held in herbaria. The study sought to determine whether saltwater species of the genus Ulva, e.g., Ulva compressa and U. intestinalis, could have been found in European freshwater ecosystems in 19th and 20th centuries. Moreover, the paper presents a method for the initial treatment of voucher specimens for viewing stained cellular structures that are extremely vulnerable to damage (the oldest specimens were more than 160 years old). -
Exhaustive Reanalysis of Barcode Sequences from Public
Exhaustive reanalysis of barcode sequences from public repositories highlights ongoing misidentifications and impacts taxa diversity and distribution: a case study of the Sea Lettuce.

Species of Ulva are frequently misiden- tified in public repositories, including herbaria and gene banks, making species identification based on traditional barcoding hazardous. We investigated the species distribution of 295 individual distromatic foliose strains from the North East Atlantic by traditional barcoding or next generation sequencing. We found seven distinct species, and compared our results with all worldwide Ulva spp sequences present in the NCBI database for the three barcodes rbcL, tuf A and the ITS1. Our results demonstrate a large degree of species misidentification in the NCBI database. We estimate that 21% of the entries pertaining to foliose species are misannotated. In the extreme case of U. lactuca, 65% of the entries are erroneously labelled specimens of another Ulva species, typically U. fenestrata. In addition, 30% of U. -

Nature Conservation 34: 217–246. https://doi.org/10.3897/ natureconservation.34.30055 Abstract The availability of quantitative long term datasets on the phytobenthic assemblages of the Mar Piccolo of Taranto (southern Italy, Mediterranean Sea), a lagoon like semi-enclosed coastal basin included in the Italian LTER network, enabled careful analysis of changes occurring in the structure of the community over about thirty years. The total number of taxa differed over the years. Thirteen non-indigenous species in total were found, their number varied over the years, reaching its highest value in 2017. The dominant taxa differed over the years. -

The green tide in the Southern Yellow Sea which has been erupting continuously for 14 years. Dominant species of the free-floating Ulva in the early stage of macroalgae bloom were Ulva compressa, Ulva flexuosa, Ulva prolifera, and Ulva linza along the coast of Jiangsu Province. In the present study, we carried out comparative studies on complete mitochondrion genomes of four kinds of bloom-forming green algae, and provided standard morphological characteristic pictures of these Ulva species. The maximum likelihood phylogenetic analysis showed that U. linza is the closest sister species of U. prolifera. This study will be helpful in studying the genetic diversity and identification of Ulva species. 1 Introduction gradually [19].

Although there is awide literature for the determination of Ulva taxa in Europe, they are among the most problematic algae to accurately identify,because they have few distinctive features, as well as ahigh intraspecificvariation. At present, the knowledge of both diversity and distribution of the genus Ulva in the Mediterranean Sea is almost entirely based on morphological studies and there is only afew published papers dealing with molecular data. Tunisia has akey position in the Mediterranean and constitutes atransition area with arich habitat diversity between eastern and western basins. The latest inventory of marine macrophytes dates back to 1987, updated in 1995. The aim of the present paper is to provide amolecular-assisted alpha taxonomy survey of Ulva spp. along Tunisian coasts, in comparison with afew Italian sites, using the tufAmarker.Nine genetic species groups were resolved, including the non indigenous species Ulva ohnoi, newly reported for Tunisia. -

This equates to an area almost one and a half times the size of Ireland. In Ireland, 16% of transitional and coastal and Coastal Bays (Sea-MAT) waters are classified as potentially eutrophic. The Sea-MAT project monitored four estuarine locations affected by Authors: Ricardo Bermejo, Svenja Heesch, Moya O’Donnell, Nessa Golden, Michéal macroalgal blooms (green tides). Macroalgal coverage and biomass abundances were considerably higher than the threshold values according to the monitoring tool used for the European Union Water Framework Directive (WFD, MacMonagail, Maeve Edwards, Edna Curley, Owen Fenton, Eve Daly and Liam Morrison 2000/60/EC). Green tides comprise laminar and tubular Ulva spp., with tubular morphologies more numerous and less susceptible to transportation out of the estuary. Tubular morphologies appear to be buried at the end of the bloom, favouring accumulation of organic matter and nutrients in sediments. These can be a potential source of nutrients for subsequent blooms, perpetuating the eutrophication problem. The arrival of the non-native species Gracilaria vermiculophylla is an additional pressure as this species is able to bloom in areas where native species cannot. -
