To address environmental pollution by plastic litter, the European Union adopted EU Directive 2019/904, so called "Single-Use Plastics Directive" (SUPD), which bans several single-use products and addresses additional items with measures such as extended producer responsibility obligatory requirements for product redesign. This study assessed potential of SUPD to reduce litter in environment three scenarios. The "best case" scenario assumed that all completely prevent targeted from getting...
Rivers are an important transport route of anthropogenic litter from inland sources toward the sea. A collaborative (i.e. citizen science) approach was used to evaluate pollution rivers in Germany: schoolchildren within project "Plastic Pirates" investigated across entire country during years 2016 and 2017 by surveying floating macrolitter at 282 sites taking 164 meso−/microplastic samples particles 24.99–5 mm, 4.99–1 respectively). Floating sighted 54% sampling quantities ranged 0 8.25...
Acoustic Harassment Devices (AHD) are widely used to deter marine mammals from aquaculture depredation, and pile driving operations that may otherwise cause hearing damage. However, little is known about the behavioural physiological effects of these devices. Here, we investigate responses harbour porpoises (Phocoena phocoena) a commercial AHD in Danish waters. Six were tagged with suction-cup-attached DTAGs recording sound, 3D-movement, GPS (n = 3) or electrocardiogram 2). They then exposed...
High numbers of harbor porpoises (Phocoena phocoena) end up as bycatch in gillnets every year. Acoustic alarms (pingers) have been demonstrated to be an efficient mitigation tool prevent this species; however, little is known about the behavioral reactions wild pingers. This knowledge important for optimizing design and use We tracked 16 with a drone recorded their behavior before during exposure pinger sounds. Range from porpoise was 158–797 m when first activated. In four exposures,...
Abstract Aim Marine and freshwater ecosystems are increasingly threatened by human activities. For over a century, scientists have been testing many biological, chemical physical questions to understand various their resilience different stressors. While the majority of experiments were conducted at small‐scale laboratory settings, lately large mesocosm become more common. Yet, it still remains unclear how scale (i.e. space) ecological complexity community versus limited number species)...
Data resulting from citizen science investigations are often questioned as most participants do not (yet) have a thorough scientific education. This is especially true for projects taking place in schools, and conducting this context further complicated by different motivations of busy school curriculum. Herein we present strategies to ensure quality data generated the project Plastic Pirates which schoolchildren investigated litter pollution at rivers. We show how formulating concise...
The harbor porpoise, Phocoena phocoena, is the only cetacean regularly occurring in Baltic Sea. During last decades, several anthropogenic activities have affected porpoises region. Most notably bycatch static fishing gear, such as gill nets, which main human-induced cause of death odontocetes. There still considerable uncertainty about factors influence amount bycatch. In present study, we reviewed data collected from 1987 to 2016 south-western was a significant difference due seasonality...
Understanding litter dynamics on riversides is challenging due to the need for extensive data. A seven-year citizen science study with schoolchildren showed no major changes in density, composition, and sources German riversides. The categorized 26,757 macrolitter items (> 2.5 cm size), mainly consisting of plastic cigarette butts, a median density 0.28 m
A cylinder plate assay procedure was studied by 10 laboratories. For premix feeds, 3 samples of bacitracin methylene disalicylic acid and zinc premixes covering the range to 50 g/lb were used. The repeatability standard deviation 2.11, reproducibility 2.13. average recovery 101.5%. method has been adopted official first action. finished 6 800 g/ton used in study. included a sample cleanup step using disposable reverse phase columns. This appears be cause poor results reported most...
