Stakeholder Perspectives on Opportunities and Challenges in Achieving Sustainable Growth of the Blue Economy in a Changing Climate
Coastal marine environments provide livelihoods as billions of people around the world depend greatly on sustainability efforts in the Blue Economy. In this study, we investigated how stakeholders from important Blue Economy sectors along the German North Sea coast perceive the impacts of climate change on their daily work life and the growth of the Blue Economy. In a two-stage approach we first conducted two stakeholder workshops with representatives from the regional sea food sector, science, NGOs and local authorities, in order to identify important issues linked to climate change affecting environment, society, economy and policy. In the second stage, we conducted semi-structured interviews with key knowledge holders from the Blue Economy, to evaluate and validate the most important issues identified during the first stage, and the impacts on the respective sectors. The workshop participants identified perceptible effects of climate change on their marine environment. Early career scientists showed that they possess a clear focus on measures for climate change adaptation, transdisciplinary approaches and knowledge transfer. The interviews revealed that the climate change effects could be perceived as both negative and positive, depending on the sector. Other issues, especially political decisions and developments are perceived to have a greater immediate impact on the Blue Economy than the slow progress of climate change effects. Additionally, increased human activities, in the form of new or intensified uses like marine renewable energy generation, have a greater influence and lead to conflicts between the Blue Economy sectors. Our study showed that economic and societal stakeholders in Germanys North Sea region are aware of climate change and already perceive its effects on their businesses. Synergies and conflicts between the sectors and political decisions might influence sustainable growth of the Blue Economy in highly contested regions, such as the North Sea basin, much stronger than the effects of climate change. This calls for a more flexible and adaptive approach to policymaking, taking into account the changing environmental, social and economic realities
Dissecting the Offshore Wind and Mariculture Multi-Use Discourse:A new Approach using targeted SWOT Analysis
Coastal seas around the world are under increasing anthropogenic pressures due to the rapid expansion of maritime industry
and coastal urbanisation. Multi-use (MU) of ocean space, meaning the use of the same space by multiple resource users, has
emerged as one strategy to address spatial conflicts resulting from an increasing use density. The proposed multi-use of
offshore wind farms (OWF) and mariculture (MAQ) is one of the most-researched examples of such a potentially symbiotic
relationship. Two decades of public and academic discourse have produced an abundance of research regarding various
facets of this particular combination. Nevertheless, the latest research projects of the EUs Horizon 2020 Research and
Innovation Programme have identified a number of persistent barriers to continued multi-use development. The past and
current public discourse has created a situation where technological readiness has outpaced societal readiness and the
discussion is often complicated by the diversity of backgrounds and perceptions of the participants of this discourse. This
study aims to dissect the common discourse on OWF and mariculture multi-use by utilising a targeted SWOT analysis
approach based on stakeholder knowledge. This approach reveals two distinct narratives based around societal and economic considerations respectively. From this, we derive a set of tailor-made recommendations for policy makers and
regulators as well as funding agencies, businesses and researchers
Contemporary Diet of Bowhead Whales (Balaena mysticetus) from the Eastern Canadian Arctic Inferred from Fatty Acid Biomarkers
The diet and feeding ecology of Eastern Canada â West Greenland bowhead whales were examined using fatty acid (FA) composition of the outer blubber layer of 50 individuals sampled during the summers of 2008 and 2009. Bowhead blubber was rich in the following FAs: 14:0, 16:0, 16:1n â 7, 18:0, 18:1n â 11, 18:1n â 9, 18:1n â 7, 20:1n â 11, 20:1n â 9, 20:1n â 7, 20:5n â 3, 22:1n â 11, 22:1n â 9, 22:5n â 3, and 22:6n â 3, which together accounted for 91% of total FAs identified. Four groups of bowhead whales were identified from their FA signatures using multivariate analysis. Long-chain monounsaturated fatty acids (MUFAs) (20:1n â 9, 20:1n â 11, 22:1n â 9 and 22:1n â 11) and polyunsaturated fatty acids (PUFAs) (20:5n â 3, 22:5n â 3, 22:6n â 3) accounted for most of the variance among groups. Whales from a single sampling site segregated into different groups, some of which included whales from other sampling sites, suggesting summer mixing of whales from different wintering areas and prey assemblages, or alternatively, selective feeding. FA composition was similar in males and females and among whales of different age classes, which suggests that these different groups shared foraging areas and had similar diets. The blubber of bowhead whales from the eastern Canadian Arctic was composed of high proportions of calanoid copepod markers (20:1n â 9 and 22:1n â 11), especially compared to the adipose tissue of western Arctic bowhead whales. This finding suggests that Calanus spp. were likely a major prey item. Given the expected change in Arctic zooplankton assemblages with climate warming, bowhead whales, through their FA biomarkers, may serve as sentinels of change in Arctic ecosystems.Afin dâapprofondir les connaissances sur la diĂšte et lâĂ©cologie alimentaire de la baleine borĂ©ale de la population EC-WG, nous avons examinĂ© la composition en acides gras de la couche de graisse sous-cutanĂ©e de 50 animaux Ă©chantilÂlonnĂ©s durant les Ă©tĂ©s 2008 et 2009. Les baleines borĂ©ales Ă©taient riches en certains acides gras (AG) notamment 14:0, 16:0, 16:1n-7, 18:0, 18:1n-11, 18:1n-9, 18:1n-7, 20:1n-11, 20:1n-9, 20:1n-7, 20:5n-3, 22:1n-11, 22:1n-9, 22:5n-3 et 22:6n-3. Ces 15 acides gras constituaient 91 % de tous les acides gras identifiĂ©s. Nous avons identifiĂ© quatre groupes de baleines Ă lâaide dâune analyse composĂ©e principale dans une analyse de fonction discriminante. Les acides gras monoinsaturĂ©s Ă longue chaĂźne (MUFAs) (20:1n-9, 20:1n-11, 22:1n-9 et 22:1n-11) et les acides gras OmĂ©ga-3 polyinsaturĂ©s (PUFAs) (20:5n-3, 22:5n-3 et 22:6n3) Ă©taient responsables de la majoritĂ© de la variance entre les groupes de baleines. Chacun des quatre groupes de baleines Ă©tait constituĂ© dâanimaux provenant dâune mĂȘme rĂ©gion ainsi que de rĂ©gions diffĂ©rentes. Ces rĂ©sultats suggĂšrent que des baleines borĂ©ales avec des sites dâhivernage diffĂ©rents partagent un mĂȘme site dâalimentation estival et/ou que les baleines borĂ©ales ont une alimentation sĂ©lective. La composition en acide gras du tissu adipeux Ă©tait semblable chez les mĂąles et les femelles ainsi quâentre les individus de diffĂ©rentes classes de tailles, ce qui suggĂšre une diĂšte similaire ou des aires dâalimentation communes. Le tissu adipeux des baleines borĂ©ales de lâArctique de lâEst canadien Ă©tait constituĂ© dâune plus grande proportion de marqueurs spĂ©cifiques de copĂ©podes calanoides (20:1n â 9 et 22:1n â 11) comparativement aux baleines borĂ©ales de lâArctique de lâOuest. Les rĂ©sultats de notre Ă©tude suggĂšrent que Calanus spp. est une proie importante de la diĂšte des baleines borĂ©ales de la population de lâest du Canada et de lâouest du Groenland. Compte tenu de lâĂ©volution attendue dans les assemblages de zooplancton de lâArctique en raison du rĂ©chauffement climatique, les baleines borĂ©ales, par leurs biomarqueurs AG, peuvent servir de sentinelles des changements dans les Ă©cosystĂšmes.
Fishing within offshore wind farms in the North Sea:Stakeholder perspectives for multi-use from Scotland and Germany
Offshore wind power generation requires large areas of sea to accommodate its activities, with increasing claims for exclusive access. As a result, pressure is placed on other established maritime uses, such as commercial fisheries. The latter sector has often been taking a back seat in the thrust to move energy production offshore, thus leading to disagreements and conflicts among the different stakeholder groups. In recognition of the latter, there has been a growing international interest in exploring the combination of multiple maritime activities in the same area (multi-use; MU), including the re-instatement of fishing activities within, or in close proximity to, offshore wind farms (OWFs). We summarise local stakeholder perspectives from two sub-national case studies (East coast of Scotland and Germany's North Sea EEZ) to scope the feasibility of combining multiple uses of the sea, such as offshore wind farms and commercial fisheries. We combined a desk-based review with 15 semi-structured qualitative interviews with key knowledge holders from both industries, regulators, and academia to aggregate key results. Drivers, barriers and resulting effects (positive and negative) for potential multi-use of fisheries and OWFs are listed and ranked (57 factors in total). Factors are of economic, social, policy, legal, and technical nature. To date, in both case study areas, the offshore wind industry has shown little interest in multi-use solutions, unless clear added value is demonstrated and no risks to their operations are involved. In contrast, the commercial fishing sector is proactive towards multi-use projects and acts as a driving force for MU developments. We provide a range of management recommendations, based on stakeholder input, to support progress towards robust decision making in relation to multi-use solutions, including required policy and regulatory framework improvements, good practice guidance, empirical studies, capacity building of stakeholders and improvements of the consultation process. Our findings represent a comprehensive depiction of the current state and key stakeholder aspirations for multi-use solutions combining fisheries and OWFs. We believe that the pathways towards robust decision making in relation to multi-use solutions suggested here are transferable to other international locations

Multi-use of the sea as a sustainable development instrument in five eu sea basins
This paper examines the concept of maritime multi-use as a territorial/SPATIAL governance instrument for the enhancement of sustainable development in five EU sea basins. Multi-use (MU) is expected to enhance the productivity of blue economy sectors, as well as deliver additional socio-economic benefits related to the environmental and social dimensions of sustainable development. The paper provides a definition of maritime multi-use and identifies the multi-uses with the highest potential in EU sea basins. In each sea basin, multi-use plays a different role as concerns sustainable development. For the Eastern Baltic Sea, the Mediterranean Sea and the Black Sea, the MU focus should remain on the environmental pillar of sustainable development. In the North Sea, North Atlantic and Western Baltic Sea, addressing social sustainability seems a key precondition for success of MU in enhancement of sustainable spatial development at sea. Moreover, it has been suggested to introduce MU key global strategies such as SDGs or Macroregional strategies and action plans and to supplement maritime spatial planning with sectoral incentives and educational efforts as key vehicles supporting MU. The paper concludes by identifying aspects which, in order to inform maritime spatial planning and maritime governance regarding a more conscious application of the aforementioned concept, require further investigation. Key tasks are related to: more profound evaluation of performance of policies supporting MUs, researching the impact of MU on societal goals and on the MU costs and benefits, including external ones, and finally identifying the impact of MU on the development of various sectors and regions on land
Trait impulsivity in Juvenile Myoclonic Epilepsy
Impulsivity is a multidimensional construct that can predispose to psychopathology. Metaâanalysis demonstrates an association between response impulsivity and Juvenile Myoclonic Epilepsy (JME), a common genetic generalized epilepsy. Here, we test the hypotheses that trait impulsivity is (i) elevated in JME compared to controls; (ii) moderated by specific seizure characteristics; and (iii) associated with psychiatric adverse effects of antiepileptic drugs (AEDs)
Monitoring the EU protected Geomalacus maculosus (Kerry Slug): what are the factors affecting catch returns in open and forested habitats?
Geomalacus maculosus is a slug species protected under EU law with a distribution limited to the west of Ireland and north-west Iberia. The species, originally thought to be limited within Ireland to deciduous woodland and peatland, has been found in a number of commercial conifer plantations since 2010. While forest managers are now required to incorporate the protection of the species where it is present, no clear species monitoring protocols are currently available. This study examines the efficacy of De Sangosse refuge traps across three habitats frequently associated with commercial forest plantations in Ireland and compares them with hand searching, a commonly used method for slug monitoring. Catch data during different seasons and under different weather conditions are also presented. Results indicate that autumn is the optimal time for sampling G. maculosus but avoiding extremes of hot or cold weather. While refuge traps placed at 1.5 m on trees in mature conifer plantations and directly on exposed rock in blanket peatlands result in significantly greater catches, hand searching is the most successful approach for clear-fell areas. Hand searches in clear-fell preceded by rain are likely to result in greater numbers caught. The results of this study form, for the first time, the basis for G. maculosus monitoring guidelines for forestry managers. © 2016, The Ecological Society of Japa
Congenital Diarrhea and Cholestatic Liver Disease: Phenotypic Spectrum Associated with MYO5B Mutations
Myosin Vb (MYO5B) is a motor protein that facilitates protein trafficking and recycling in polarized cells by RAB11- and RAB8-dependent mechanisms. Biallelic MYO5B mutations are identified in the majority of patients with microvillus inclusion disease (MVID). MVID is an intractable diarrhea of infantile onset with characteristic histopathologic findings that requires life-long parenteral nutrition or intestinal transplantation. A large number of such patients eventually develop cholestatic liver disease. Bi-allelic MYO5B mutations are also identified in a subset of patients with predominant early-onset cholestatic liver disease. We present here the compilation of 114 patients with disease-causing MYO5B genotypes, including 44 novel patients as well as 35 novel MYO5B mutations, and an analysis of MYO5B mutations with regard to functional consequences. Our data support the concept that (1) a complete lack of MYO5B protein or early MYO5B truncation causes predominant intestinal disease (MYO5B-MVID), (2) the expression of full-length mutant MYO5B proteins with residual function causes predominant cholestatic liver disease (MYO5B-PFIC), and (3) the expression of mutant MYO5B proteins without residual function causes both intestinal and hepatic disease (MYO5B-MIXED). Genotype-phenotype data are deposited in the existing open MYO5B database in order to improve disease diagnosis, prognosis, and genetic counseling.This research was funded by JubilĂ€umsfonds der Ăsterreichischen Nationalbank, grant no.16678 (to A.R.J.), grant no. 18019 (to G.-F.V.) and Tiroler Wissenschaftsfonds, grant No. 0404/2386 (toG.-F.V.).info:eu-repo/semantics/publishedVersio
Conceptual and Visual Features Contribute to Visual Memory for Natural Images
We examined the role of conceptual and visual similarity in a memory task for natural images. The important novelty of our approach was that visual similarity was determined using an algorithm [1] instead of being judged subjectively. This similarity index takes colours and spatial frequencies into account. For each target, four distractors were selected that were (1) conceptually and visually similar, (2) only conceptually similar, (3) only visually similar, or (4) neither conceptually nor visually similar to the target image. Participants viewed 219 images with the instruction to memorize them. Memory for a subset of these images was tested subsequently. In Experiment 1, participants performed a two-alternative forced choice recognition task and in Experiment 2, a yes/no-recognition task. In Experiment 3, testing occurred after a delay of one week. We analyzed the distribution of errors depending on distractor type. Performance was lowest when the distractor image was conceptually and visually similar to the target image, indicating that both factors matter in such a memory task. After delayed testing, these differences disappeared. Overall performance was high, indicating a large-capacity, detailed visual long-term memory
