“…Different hydrodynamics, such as more shelter due to new structures may lead to colonization of organisms very different to those on nearby hard substrates and thereby establish and spread nonindigenous species [57]. On wind turbine constructions in the North Sea and in the Baltic Sea the presence of alien species has been recorded [58–60] and may provide stepping-stones for spread, which could facilitate the establishment of the new taxa in the recipient region. …”

The rapid worldwide growth of offshore renewable energy production will provide marine organisms with new hard substrate for colonization, thus acting as artificial reefs. The artificial reef effect is important when constructing, for example, scour protections since it can generate an enhanced habitat. Specifically, artificial structures can create increased heterogeneity in the area important for species diversity and density. Offshore energy installations also have the positive side effect as they are a sanctuary area for trawled organisms. Higher survival of fish and bigger fish is an expected outcome that can contribute to a spillover to outer areas. One negative side effect is that invasive species can find new habitats in artificial reefs and thus influence the native habitats and their associated environment negatively. Different scour protections in offshore wind farms can create new habitats compensating for habitat loss by offshore energy installations. These created habitats differ from the lost habitat in species composition substantially. A positive reef effect is dependent on the nature and the location of the reef and the characteristics of the native populations. An increase in surface area of scour protections by using specially designed material can also support the reef effect and its productivity.

In most freshwater ecosystems, aquatic insects are dominant in terms of diversity; however, there is a disproportionately low number of records of alien species when compared to other freshwater organisms. The Chironomidae is one aquatic insect family that includes some examples of alien species around the world. During a study on aquatic insects in Amazonas state (Brazil), we collected specimens of Chironomidae that are similar, at the morphological level, to Chironomus kiiensis Tokunaga and Chironomus striatipennis Kieffer, both with distributions restricted to Asia. The objectives of this study were to provide morphological information on this Chironomus population, to investigate its identity using DNA barcoding and, to provide bionomic information about this species. Chironomus DNA barcode data were obtained from GenBank and Barcode of Life Data Systems (BOLD) and, together with our data, were analyzed using the neighbor-joining method with 1000 bootstrap replicates and the genetic distances were estimated using the Kimura-2-parameter. At the morphological level, the Brazilian population cannot be distinguished either from Chironomus striatipennis or Chironomus kiiensis, configuring a species complex but, at the molecular level our studied population is placed in a clade together with Chironomus striatipennis, from South Korea. Bionomic characteristics of the Brazilian Chironomus population differ from the ones of Chironomus kiiensis from Japan, the only species in this species complex with bionomic information available. The Brazilian Chironomus population has a smaller size, the double of the number of eggs and inhabits oligotrophic water, in artificial container. In the molecular analysis, populations of Chironomus striatipennis and Chironomus kiiensis are placed in a clade, formed by two groups: Group A (which includes populations from both named species, from different Asiatic regions and our Brazilian population) and Group B (with populations of Chironomus kiiensis from Japan and South Korea). Genetic distance between the Brazilian population and specimens in Group A suggests that it was recently introduced in Brazil, and that its country of origin is probably South Korea.

“…The effects of decommissioning are currently unknown. Offshore wind farms are likely to compromise D2, as their hard substrate, provided by pylons, could act as 'stepping stones' and to facilitate the spread of nonindigenous species (Brodin and Andersson 2009). This is a good example of environmental effects that may occur at multiple spatial-within and beyond the planned area-and temporal-at least over the lifetime of the OWF-scales.…”

ABSTRACT. The European Union Marine Strategy Framework Directive requires the Good Environmental Status of marine environments in Europe's regional seas; yet, maritime activities, including sources of marine degradation, are diversifying and intensifying in an increasingly globalized world. Marine spatial planning is emerging as a tool for rationalizing competing uses of the marine environment while guarding its quality. A directive guiding the development of such plans by European Union member states is currently being formulated. There is an undeniable need for marine spatial planning. However, we argue that considerable care must be taken with marine spatial planning, as the spatial and temporal scales of maritime activities and of Good Environmental Status may be mismatched. We identify four principles for careful and explicit consideration to align the requirements of the two directives and enable marine spatial planning to support the achievement of Good Environmental Status in Europe's regional seas.Key Words: DPSWR; Good Environmental Status; marine spatial planning; maritime spatial planning; spatial scale temporal scale THE POLICY CONTEXT Global and regional assessments confirm that the capacity of our ocean ecosystems to continue to deliver ecosystem services that underpin human well-being is declining because of human activities (e. The EU is drafting a directive on MSP specifically to give cross-border cooperation a firm legal footing (European Commission 2013). Although the responsibility for MSP lies at the national level and addresses maritime activities in a nation's Exclusive Economic Zone (EEZ), a transnational, subregional, and even a regional sea perspective is called for when maritime activities and/or their effects cross national borders (Gee et al. 2011). This creates considerable challenges for the planning process and stakeholder consultation (e.g., Argardy et al. 2011, Maritime Spatial Planning in the North Sea 2012, Halpern et al. 2012, Jentoft and Knol 2014. However, it also provides challenges for assessing effects on the marine environment given the requirement under the MSFD to achieve GES at subregional and 9]). We address effects on the marine environment by examining the spatial and temporal dimensions of both GES and MSP.We examine the role of MSP in an ecosystem approach and MSP's potential contributions to achieving GES. We aim to assess whether mismatches of spatial and temporal scales between MSP and marine ecosystems might constrain this role and these contributions. The methodology is based on the Driver Pressure State Welfare Response (DPSWR) framework (Cooper 2013). Findings are illustrated by two case studies representing aspects of traditional and emerging sea use. We use DPSWR to provide a context for MSP in an ecosystem approach to achieve GES. We then compare the spatial and temporal scales of MSP and GES. We identify a number of principles that require explicit consideration by MSP. These principles address the specific focus of our work; namely, the spatial an...
