| The aim of this study was to evaluate the vigour and physiological quality of seeds of Pochota fendleri in two weight classes, stored in different types of packaging over a period of 28 months. The experimental design was completely randomised, with treatments arranged in a 2 x 3 x 4 factorial scheme (2 seed sizes x 3 types of packaging x 4 storage periods), with four repli-cations. The stored seeds were evaluated for germination percentage and ger-mination speed index every six months up to 28 months. At 28 months, the percentage incidence of fungi on the seeds was also determined. The seeds of Pochota fendleri remain viable and of high quality for a period of 28 months storage. A PET bottle kept in the refrigerator is recommended to store Pochota... |

| Plastics and other artificial materials pose new risks to the health of the ocean. Anthropogenic debris travels across large distances and is ubiquitous in the water and on shorelines, yet, observations of its sources, composition, pathways, and distributions in the ocean are very sparse and inaccurate. Total amounts of plastics and other man-made debris in the ocean and on the shore, temporal trends in these amounts under exponentially increasing production, as well as degradation processes, vertical fluxes, and time scales are largely unknown. Present ocean circulation models are not able to accurately simulate drift of debris because of its complex hydrodynamics. In this paper we discuss the structure of the future integrated marine debris observing... |

| Microplastic litter is a pervasive pollutant present in marine systems across the globe. The legacy of microplastics pollution in the marine environment today may remain for years to come due to the persistence of these materials. Microplastics are emerging contaminants of potential concern and as yet there are few recognized approaches for monitoring. In 2008, the EU Marine Strategy Framework Directive (MSFD, 2008/56/EC) included microplastics as an aspect to be measured. Here we outline the approach as discussed by the European Union expert group on marine litter, the technical Subgroup on Marine litter (TSG-ML), with a focus on the implementation of monitoring microplastics in seawater in European seas. It is concluded that harmonization and coherence... |
