Background
Trophic interactions are key processes, which determine the ecological function and performance of organisms. Many decapod crustaceans feed on plant material as a source for essential nutrients, e.g. polyunsaturated fatty acids. Strictly herbivorous feeding appears only occasionally in marine decapods but is common in land crabs. To veri...
Predicting range expansion of invasive species is one of the key challenges in ecology. We modelled the phenological window for successful larval release and development (WLR) in order to predict poleward expansion of the invasive crab Hemigrapsus sanguineus along the Atlantic coast of North America and north Europe. WLR quantifies the number of op...
This open access book summarizes peer-reviewed articles and the abstracts of oral and poster presentations given during the YOUMARES 9 conference which took place in Oldenburg, Germany, in September 2018. The aims of this book are to summarize state-of-the-art knowledge in marine sciences and to inspire scientists of all career stages in the develo...
This open access book presents the proceedings volume of the YOUMARES 8 conference, which took place in Kiel, Germany, in September 2017, supported by the German Association for Marine Sciences (DGM). The YOUMARES conference series is entirely bottom-up organized by and for YOUng MARine RESearchers. Qualified early career scientists moderated the s...
YOUMARES is an annual early-career scientist conference series.
The invasive Asian shore crab Hemigrapsus sanguineus and the native European
green crab Carcinus maenas share intertidal habitats along European North Atlantic shores and may compete for food. We evaluated the energy-storing capacities of the 2 species and determined their dietary preferences by means of lipid analysis and fatty acid trophic marker...
The invasive Asian shore crab Hemigrapsus sanguineus is now the second most abundant intertidal crab in the North Sea after the native European green crab Carcinus maenas. To compare their respiratory performance and energy expenditures, we measured standard respiration rates of both species from around the island of Helgoland, North Sea, Germany (...
YOUMARES is an annual early-career scientist conference series. It is an initiative of the German Society for Marine Research (DGM) and takes place in changing cities of northern Germany. The conference series is organized in a bottom-up structure: from and for YOUng MARine RESearchers. In this chapter, we describe the concept of YOUMARES together...
The Asian shore crab Hemigrapsus sanguineus is native to the coasts of China, Korea and Japan. It first invaded the U.S. east coast in the late 1980s and its present range extends from North Carolina to Maine. It was detected in France and the Netherlands in 1999. Nowadays, H. sanguineus is fully established at the European Atlantic coast. It can b...
The Asian shore crab Hemigrapsus sanguineus (De Haan, 1853) has recently established populations in the North Sea and now occurs within the native ranges of the green crab Carcinus maenas (Linnaeus, 1758). To determine potential competitive effects and to assess the progress of the invasion, species-specific population characteristics (numerical ab...
Introduction
Jellyfish stings are common injuries for tourists visiting the German coasts and regularly require consultations from the regional lifeguard service.
Objectives
This review aims to summarize the evidence for the various therapeutic options for treating jellyfish stings.
Method
We performed a selective literature research in the medic...
Invading non-native species can have profound effects on native biodiversity and related ecosystem services. Investigating the introduction pathways and vectors, invasion pattern and status as well as ecology and ecophysiology of non-native species, especially invaders, is crucial to understand and predict their potential impact. This session provi...
The invasion of non-native species can have profound effects on native populations and communities, ecosystem functioning and even human health and economics. Investigating invasion patterns, mechanisms and their effects receives increasing attention as the number of reported invasions increased almost exponentially over the past 200 years. This se...
The distribution at sea of upper trophic levels—seabirds and marine mammals—is depending on their food availability: high concentrations reflect high prey abundance and thus high biological production. Polar marine ecosystems are characterized by low biodiversity and high biological patchiness. The distribution of predators, as a consequence, shows...
The aim of this study was to determine the macro‐parasitic infestation level of oysters from the southern German Bight focussing on copepods of the genus Mytilicola. Crassostrea gigas, Ostrea edulis and Mytilus edulis were collected at five locations: three nearshore sites in the eastern Wadden Sea and two offshore cultivation sites in the German B...

The European species Carcinus maenas and the Asian shore crab Hemigrapsus sanguineus invaded different coastal areas around the world. While their invasion history and ecology has been thoroughly investigated, physiological properties of H. sanguineus are virtually unknown.
The aim of this study was to compare the metabolic energy demand of both crab species and - based on these data - to assess their potential dietary impact on the ecosystem. Respiration measurements were conducted with a newly constructed flow-through system covering a temperature range naturally experienced by these crabs. Both species were analyzed on the island of Helgoland, Germany.
A general linear mixed-effects model (LMM) was applied to test for the effects of species, temperature, biomass and sex on respiration rates.
From the full model, two separated LMMs were created for either species. They allowed establishing species-specific equations for the prediction of respiration rates y (nmol d-1 g-1) for a crab of any given mass xMass (g) at any given ambient temperature xTemp (°C).
By applying the diet-dependent respiratory quotient, oxygen uptake may be used to calculate carbon uptake and metabolic energy demand either for single crabs or for entire populations of a given area.
