Artist, tower, books: the memory theatre of Richard Cockle Lucas
Richard Cockle Lucas (1800-1883) has been remembered for forging a Leonardo and marrying a fairy. This distorting vision, juxtaposed with his protean versatility and originality, makes Lucas an awkward subject for historiography to get a hold on. Lucas was a sculptor, printmaker, photographer, …

A temporal investigation of Europe-wide drivers of cockle Cerastoderma edule biology, health and population dynamics
The common cockle Cerastoderma edule is an economically, ecologically and culturally important bivalve species and provides a range of ecosystem services. However, increasing reports of cockle mass mortalities, coinciding with reduced harvests, are a concern for various stakeholders. The factors …

Oystercatchers and cockles : a predatory-prey study
Oystercatchers Haematopus ostralegus and cockles Cerastoderma edule were studied with the aim of understanding the behaviour of predators and the consequences which this behaviour has on the cockle population. At Traeth Melynog, Anglesey, the cockle density declined down the shore and those at the …

Isolation and characterisation of novel glycosaminoglycan-like polysaccharides derived from marine molluscs with antiproliferative activity
… novel polysaccharides isolated from the common cockle (Cerastoderma edule) with antiproliferative activity, using the cetylpyridinium chloride precipitation method. Marine polysaccharides have exhibited in-vitro potent antiproliferative activity, leading to induced apoptotic cellular death in …

Investigating the anti-proliferativeproperties and their mechanism(s) of actionof marine derived glycosaminoglycans fromtwo marine sources
… differences between the already studied cockle derived GAGs and prawn derived GAGs. Nuclear magnetic resonance (NMR) spectroscopy was employed to identify differences between the prawn and cockle derived GAGs. External monosaccharide and disaccharide analysis was also performed on the …

Evaluation of spatial and temporal models to assess the bioaccumulation of trace metals in marine invertebrates
… for biomonitoring was investigated, e.g. of the cockle Cerastoderma edule and the brown shrimp Crangon crangon as important representatives of the benthic communities in the Wadden Sea in the Wadden Sea and the southern North Sea with substantial economic impact. For both species the problem of …

The Fate and Effects of Contaminants in Estuarine Environments
… by the analysis of the material strength of cockle shell. From this research, lead, cadmium and zinc were found to be the most concerning polluting elements in the study location, with levels above sedimentary ANZECC safety guidelines. Phosphorus was found in high concentration in urban and …

Sandplay : a comparative study
Differences in play themes, play characteristics, object use, and narratives, of coping and difficulty coping children were examined. Five subjects, from grades 2 and 3, were each assigned to the coping group (CG) and difficulty coping group (DCG). They participated individually in sandplay, on …

Genomic tools to investigate and characterise emerging and reemerging disease in aquatic invertebrates
… associated with mortality events in the common cockle (Cerastoderma edule), and demonstrate that multiple pathogens and environmental stressors could contribute to poor health outcomes in bivalves. In shrimp (Penaeus monodon), comprehensive virome profiling revealed that healthy individuals …

Arsenic in the Pak Pa-Nang River Basin, Thailand
… reference materials and real samples, mussel, cockle, green seaweed, brown seaweed and sediment collected from the Tamar Estuary, UK. Fish samples from the Pak Pa-Nang Estuary showed a range for total arsenic concentration, up to 17 µg gˉ¹ dry mass. The highest total arsenic found in plant …

The genetic structure of New Zealand's coastal benthos: using the estuarine clam Austrovenus stutchburyi, to determine rates of gene flow and population connectivity
For many benthic marine taxa, dispersal over large distances is dependent on a pelagic larval phase. It is through the dispersal process that benthic taxa can found new populations, colonise disturbed or degraded habitats and achieve genetic exchange between geographically separated subpopulations. …

Understanding and minimizing the impacts of host-pathogen-environment interactions in the Pacific oyster Crassostrea gigas
… Green shore crabs Carcinus maenas and edible cockles Cerastoderma edule were collected at the oyster trestles and 500 m on the high shore at two culture sites, and were screened for OsHV-1 µVar by polymerase chain reaction (PCR), quantitative PCR (qPCR) and in situ hybridisation (ISH). OsHV-1 …
