Many young students dream about a career working with marine mammals. Although marine mammal jobs are limited and highly competitive, there are several ways to obtaining them. But, there is no magic formula to pursue a career in marine mammal science. We describe various skill sets and experiences that can improve your chances. Not the least, it is...
In recent decades, global plastic consumption has rapidly increased. Large quantities of plastics enter the environment in various ways, often ending up in the oceans. Plastic debris is nowadays found in any aquatic ecosystems. Due to its long durability, plastics may drift around with ocean currents for decades. Nowadays, plastic debris can be fou...
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 to prevent bycatch of this species; however, little is known about the behavioral reactions of wild porpoises to pingers. This knowledge is important for optimizing the de...
The harbor porpoise, Phocoena phocoena , is the only cetacean regularly occurring in the Baltic Sea. During the last decades, several anthropogenic activities have affected porpoises in the Baltic region. Most notably is bycatch in static fishing gear, such as gill nets, which is the main human-induced cause of death in odontocetes. There is still...
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 the litter pollution of rivers in Germany: schoolchildren within the project “Plastic Pirates” investigated rivers across the entire country during the years 2016 and 2017 by survey...
Aim
Marine and freshwater ecosystems are increasingly threatened by human activities. For over a century, scientists have been testing many biological, chemical and physical questions to understand various ecosystems and their resilience to different stressors. While the majority of experiments were conducted at small‐scale laboratory settings, lat...
The permanent presence of microplastics in the marine environment is considered a global threat to
several marine animals. Heavy metals and microplastics are typically included in two different classes
of pollutants but the interaction between these two stressors is poorly understood. During 14 days of experimental manipulation, we examined the ads...
Nowadays, plastic debris are omnipresent in the oceans and became a major environmental problem over the years. Additionally, plastics are fragmentating, yielding microplastics (< 5 mm). Microplastics are currently accumulating in marine sediments and can pose a risk for deposit feeding invertebrates. In a 2-month laboratory experiment, I investiga...
Microplastics, which are accumulating in marine sediments, are assumed to pose a risk for deposit feeding invertebrates. We tested whether the fiddler crab Uca rapax ingests and retains microplastics in its body. Furthermore, we investigated whether retention rates depend on (a) the quality of the marine environment in which the plastics were pre-w...
Anthropogenic CO2 emission will lead to an increase in seawater pCO2 of up to 80–100 Pa (800–1000 μatm) within this century and to an acidification of the oceans. Green sea urchins (Strongylocentrotus droebachiensis) occurring in Kattegat experience seasonal hypercapnic and hypoxic conditions already today. Thus, anthropogenic CO2 emissions will ad...
