Records are from datasets made available via the iRecord verification process from the project website that links to the BRC database for verification purposes. Zero abundance records and associated environmental data are not included.

The species is characterized by a distinct eyespot, rectangular nucleus, a large number of Golgi bodies, two types of flagellar pit hairs and a characteristic type of cell division. In nature, the species was found in a wide range of temperatures (48°C down to 28°C) and salinities, from hypersaline (up to 350 psu) down to marine (c. 35 psu) conditions. Phylogenetic analysis based on 18S rDNA sequence data showed that T. indica is most closely related to unidentified Tetraselmis strains from a salt lake in North America.

The test procedure included a five day storage period of organisms in the control and treated tanks as specifically advised in the type approval procedure for shipboard and land-based tests described in the IMO Guideline ‘G8’. The configurations and materials of control and treated tanks used in each test location were different resulting in invalid test results at one testing location.

Until recently, a heavily prescriptive National Curriculum has prevented educationists from devising and delivering more effective science education. However, since 2008 a minimum-content model has been adopted for key stage 3, permitting educators greater flexibility in the teaching process. In line with these changes, specific pedagogies such as pupil-led enquiry, cross-curricular learning and themed teaching have increasingly been advocated as means of addressing the attitudinal crisis towards science. This article reports on the use of themed debate as a way of facilitating genuine engagement with science by addressing the pertinent socio-scientific issue' Is shipping a sustainable form of transport for the 21st century?'

For the many fields of marine research, this is a particularly powerful approach which should not be overlooked. The sheer scale of coastal and ocean environments mean that it would take several lifetimes for scientists to study them alone. By collaborating with citizens, a much greater number of people can be mobilized to gather a wealth of data and develop new scientific knowledge and understanding. The variety of data types which are amenable to Citizen Science, as outlined in the position paper, are great, meaning that there could be a project to suit everyone. Citizen Science can also enable participants to improve their Ocean Literacy, gain new skills and experiences, and can also empower them to participate in the process of delivering future marine policy.Now, more than ever, marine science research is needed to understand the impacts of a worl...

Relatively large-celled unicellular eukaryotic phytoflagellates (such as Tetraselmis and Scherffelia), traditionally placed in Prasinophyceae but now considered as members of Chlorodendrophyceae (core Chlorophyta), have retained some primitive characteristics of prasinophytes. These organisms share several ultrastructural features with the other core chlorophytes (Trebouxiophyceae, Ulvophyceae and Chlorophyceae). However, the role of Chlorodendrophycean algae as the evolutionary link between cellular individuality and cellular cooperation has been largely unstudied. Here, we show that clonal populations of a unicellular chlorophyte, Tetraselmis indica, consist of morphologically and u...
