When the small ones tease the largest: Microplastic and phthalate ester occurrence in cetaceans occasionally found in the German North Sea and Baltic Sea Open
Living in potentially burdened waters and prey on loaded species, marine mammals are sentinels for microplastic (MP) pollution. Here, seven different species of cetaceans were investigated covering baleen (Mysticeti) and toothed (Odontocet…

Characterization of three plastic forms: Plasticoncrete, plastimetal and plastisessiles Open
Plastic forms, including plastiglomerate, pyroplastic, plasticrusts, anthropoquinas, plastistone and plastitar, were recorded worldwide. These plastic forms derive from geochemical or geophysical interactions such as heat-induced plastic f…

Matter of fac(ies)t? - Microplastic findings in stranded cetaceans along the German coastlines Open
Microplastics occur in marine habitats worldwide. They have been reported from locations as remote and pristine as the Arctic and Antarctic, beyond organisms of several trophic levels. Microplastic ingestion in animals can either happens i…

Electrofishing distances for sampling fish assemblages in oxbow lakes of the River Rhine Open
Assessment of fish assemblage structure depends on representative sampling. In contrast to lotic water bodies, recommendations for a general study design are sparse for lentic water bodies. Therefore, we evaluated the fish assemblages in d…

First Evidence of Retrospective Findings of Microplastics in Harbour Porpoises (Phocoena phocoena) From German Waters Open
Microplastic ingestion by lower trophic level organisms is well known, whereas information on microplastic ingestion, egestion and accumulation by top predators such as cetaceans is still lacking. This study investigates microplastics in i…

Wrapped up in plastic Open
Plastic is a versatile material appreciated for its durability and wide applicability in everyday products like food containers, beverage bottles, and medical devices. However, mismanaged plastic waste frequently washes into streams and ri…

Low‐cost microplastic visualization in feeding experiments using an ultraviolet light‐emitting flashlight Open
Microplastics are pollutants threatening the health of marine, freshwater and terrestrial organisms. To analyze whether an organism is able to ingest microplastics, the organism is usually fed with expensive fluorescent microbeads and plac…

Microplastics of different characteristics are incorporated into the larval cases of the freshwater caddisfly Lepidostoma basale Open
Plastic pollution is present in aquatic systems worldwide. While numerous studies have investigated microplastic interactions with marine organisms, microplastic effects on freshwater organisms, especially insects, have been rarely studied…

River bank stabilisation by bioengineering: potentials for ecological diversity Open
Riverbanks hold a key position on functionality of floodplains as they constitute the gradual transition between aquatic and terrestrial ecosystems. However, due to technical constructions the majority of riverbanks in temperate regions ar…
