The Seaweed Flora of a Young Semi-Enclosed Sea: the Baltic
HELGOL.~NDER MEERESUNTERSUCHUNGEN Helgol&nder Meeresunters. 42, 243-250 (1988) The seaweed flora of a young semi-enclosed sea: The Baltic. Salinity as a possible agent of flora divergence* G. Russell Department of Botany, The University/Liverpool L69 3BX, England ABSTRACT: The salinity tolerances of Baltic and Atlantic populations of Fucus vesiculosus and Chorda filum have been measured using net photosynthesis as an index of tissue damage. Atlantic Fucus proved to have a broader salinity tolerance than Atlantic Chorda, a result which is consistent with others published on the tolerances of intertidal and sublittoral marine species. The optimum salinity for all Atlantic plants was 11 or 34%0, but that of all Baltic plants was 6%o. Baltic Fucus and Chorda were different in breadth of tolerance, in spite of the fact that they inhabit the same sublittoral habitat. This difference is interpreted in relation to their respective life-forms, Fucus being perennial and Chorda annual. Fucus is therefore present as a macrothallus at all times of year, including the critical low-salinity period of the spring ice-melt. Chorda evades damage by existing as a resistent microthallus at this time. It is concluded that the distinctive character of Baltic marine algae deserves nomenclatural recognition at some level below that of the species. The rank of subspecies would appear the most appropriate of those hsted in the Code, but none of those available is able adequately to express the patterns of variation now being reported. INTRODUCTION The Baltic Sea, like the Mediterranean, has a very narrow exit to the Atlantic Ocean, and the fact that the flow of its seawater is almost always in an outward direction, serves only to increase its isolation. -
William Roscoe - Poems
Classic Poetry Series William Roscoe - poems - Publication Date: 2012 Publisher: Poemhunter.com - The World's Poetry Archive William Roscoe() He was born in Liverpool, where his father, a market gardener, kept a public house called the Bowling Green at Mount Pleasant. Roscoe left school at the age of twelve, having learned all that his schoolmaster could teach. He assisted his father in the work of the garden, but spent his leisure time on reading and study. "This mode of life," he says, "gave health and vigour to my body, and amusement and instruction to my mind; and to this day I well remember the delicious sleep which succeeded my labors, from which I was again called at an early hour. If I were now asked whom I consider to be the happiest of the human race, I should answer, those who cultivate the earth by their own hands." At fifteen he began to look for a suitable career. A month's trial of bookselling was unsuccessful, and in 1769 he was articled to a solicitor. Although a diligent student of law, he continued to read the classics, and made the acquaintance with the language and literature of Italy which was to dominate his life. His poem, Mount Pleasant, was written when he was sixteen, and together with other verses, now forgotten, won the esteem of good critics. In 1774 he went into business as a lawyer, and in 1781 married Jane, second daughter of William Griffies, a Liverpool tradesman; they had seven sons and three daughters. Roscoe had the courage to denounce the African slave trade in his native town, where much of the wealth came from slavery. -

Approved Conservation Advice for Stackhousia Annua (Annual Stackhousia)
This Conservation Advice was approved by the Minister / Delegate of the Minister on: 1/10/2008 Approved Conservation Advice (s266B of the Environment Protection and Biodiversity Conservation Act 1999) Approved Conservation Advice for Stackhousia annua (Annual Stackhousia) This Conservation Advice has been developed based on the best available information at the time this conservation advice was approved; this includes existing plans, records or management prescriptions for this species. Description Stackhousia annua, Family Stackhousiaceae, also known as Annual Stackhousia or Annual Candles, is a slender, erect, hairless annual growing to 19 cm (Barker, 1984). Leaves are 7– 25 mm long; basal leaves are narrowly spatulate and upper leaves are obovate (egg-shaped) to linear. Flowering occurs from September to October. The cream coloured flowers grow at the ends of stems in a dense, cylindrical floral spike (State Herbarium of South Australia, 2007). Conservation Status Annual Stackhousia is listed as vulnerable. This species is eligible for listing as vulnerable under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth) (EPBC Act) as, prior to the commencement of the EPBC Act, it was listed as vulnerable under Schedule 1 of the Endangered Species Protection Act 1992 (Cwlth). This species is also listed as vulnerable on the National Parks and Wildlife Act 1972 (South Australia). Distribution and Habitat Annual Stackhousia is endemic to near-coastal areas of south-west Yorke Peninsula and south-east Eyre Peninsula, South Australia (Barker, 1977; Barker, 1984; Pobke, 2007). This species was thought to occur in north-west Victoria and the South Australian mallee region (Walsh & Entwisle, 1999), but these records are now called a subspecies of Stackhousia aspericocca (Ross & Walsh, 2003). -

Fingerprinting Marine Macrophytes in Blue Carbon Habitats
Fingerprinting Marine Macrophytes in Blue Carbon Habitats Thesis by Alejandra Ortega In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in Bioscience King Abdullah University of Science and Technology Thuwal, Kingdom of Saudi Arabia November, 2019 2 EXAMINATION COMMITTEE PAGE The thesis of Alejandra Ortega is approved by the examination committee. Committee Chairperson and Thesis Supervisor: Prof. Carlos M. Duarte Committee Members: Prof. Mark Tester, Prof. Takashi Gojobori, and Prof. Hugo de Boer [External] 3 © November, 2019 Alejandra Ortega All Rights Reserved 4 ABSTRACT Fingerprinting Marine Macrophytes in Blue Carbon Habitats Alejandra Ortega Seagrass, mangrove, saltmarshes and macroalgae - the coastal vegetated habitats, offer a promising nature-based solution to climate change mitigation, as they sequester carbon in their living biomass and in marine sediments. Estimation of the macrophyte organic carbon contribution to coastal sediments is key for understanding the sources of blue carbon sequestration, and for establishing adequate conservation strategies. Nevertheless, identification of marine macrophytes has been challenging and current estimations are uncertain. In this dissertation, time- and cost-efficient DNA-based methods were used to fingerprint marine macrophytes and estimate their contribution to the organic pool accumulated in blue carbon habitats. First, a suitable short-length DNA barcode from the universal 18S gene was chosen among six barcoding regions tested, as it successfully recovered degraded DNA from sediment samples and fingerprinted marine macrophyte taxa. Second, an experiment was performed to test whether the abundance of eDNA represents the content of organic carbon within the macrophytes; results supported this notion, indicating a positive correlation (R2 = 0.85) between eDNA and organic carbon.
