    Description: Widespread global declines in shellfish reefs (ecosystem-forming bivalves such as oysters and mussels) have led to growing interest in their restoration and protection. With restoration projects now occurring on four continents and in at least seven countries, global restoration guidelines for these ecosystems have been developed based on experience over the past two decades. The following key elements of the guidelines are outlined: (a) the case for shellfish reef resto- ration and securing financial resources; (b) planning, feasibility, and goal set- ting; (c) biosecurity and permitting; (d) restoration in practice; (e) scaling up from pilot to larger scale restoration, (f) monitoring, (g) restoration beyond oyster reefs (specifically mussels), and (h) successful communication for shell- fish reef restoration projects.

    Description: Global climate change affects marine fish through drivers such as ocean warming, acidification and oxygen depletion, causing changes in marine ecosystems and socioeconomic impacts. While experimental and observational results can inform about anticipated effects of different drivers, linking between these results and ecosystem-level changes requires quantitative integration of physiological and ecological processes into models to advance research and inform management. We give an overview of important physiological and ecological processes affected by environmental drivers. We then provide a review of available modelling approaches for marine fish, analysing their capacities for process-based integration of environmental drivers. Building on this, we propose approaches to advance important research questions. Examples of integration of environmental drivers exist for each model class. Recent extensions of modelling frameworks increase the potential for including detailed mechanisms and improving model projections. Experimental results on energy allocation, behaviour and physiological limitations will advance the understanding of organism-level trade-offs and thresholds in response to multiple drivers. More explicit representation of life cycles and biological traits can improve description of population dynamics and adaptation, and data on food web topology and feeding interactions help to detail the conditions for possible regime shifts. Identification of relevant processes will also benefit the coupling of different models to investigate spatial–temporal changes in stock productivity and integrated responses of social–ecological systems. Thus, a more process-informed foundation for models will promote the integration of experimental and observational results and increase the potential for model-based extrapolations into a future under changing environmental conditions.

    Description: There is still considerable debate about which mechanisms drive the relationship between biodiversity and ecosystem function (BEF). Although most scientists agree on the existence of two underlying mechanisms, complementarity and selection, experimental studies keep producing contrasting results on the relative contributions of the two effects. We present a spatially explicit resource competition model and investigate how the strength of these effects is influenced by trait and environmental variability, resource distribution, and species pool size. Our results demonstrate that the increase of biomass production with increasing species numbers depends on the concurrence of environmental and trait variability: BEF relationships are stronger if functionally different species coexist in a landscape with heterogeneous resource supply. These large biodiversity effects arise from complementarity effects, whereas selection effects are maximized when broad trait ranges coincide with narrow ranges of resource supply ratios. Our results will therefore help to resolve the debate on complementarity and selection mechanisms.

    Description: Many hope that the Global Stocktake under the Paris Agreement can become a catalyst for increased mitigation ambition over time. Based on different theories of change, this paper outlines four governance functions for the Global Stocktake. It can contribute to the Paris Agreement as a pacemaker (stimulating and synchronizing policy processes across governance levels), by ensuring accountability of Parties, by enhancing ambition through benchmarks for action and transformative learning, and by reiterating and refining the guidance and signal provided from the Paris Agreement. The paper further outlines process- and information-related preconditions that would enable an ideal Global Stocktake.

    Description: In July 2007 GFZ hosted ILP’s first Potsdam Conference, titled “Frontiers in Integrated Solid Earth Sciences”. The results of this meeting were presented in an over 400 pages large Springer book, the first volume of a new series on the International Year of Planet Earth (IYPE). In October 2010 ILP’s Second Potsdam Conference took place, entitled “Solid Earth – Basic Science for the Human Habitat”, again in Potsdam. More than 70 scientists from more than 20 states worldwide came together and shared their results, ideas and visions. This time, in September 2015, ILP’s 35th birthday was the motivation for “Celebrating Excellence in Solid Earth Sciences”. Together with more than 50 scientists, members of the ILP Task Forces and Coordinating Committees, the ILP bureau and ILP’s office came together for three days in September.

    Description: The Collisional Orogeny in the Scandinavian Caledonides (COSC) scientific drilling project focuses on mountain building processes in a major mid‐Paleozoic orogen in western Scandinavia and its comparison with modern analogues. The project investigates a subduction‐generated complex (Seve Nappes) and how these in part under ultra‐high pressure conditions metamorphosed outer continental margin and continent‐ocean transition zones (COT) assemblages were emplaced onto the Baltoscandian platform and there influenced the underlying allochthons and the basement in a section provided by two fully cored 2.5 km deep drill holes. This operational report concerns the first drill hole, COSC‐1 (ICDP 5054‐1‐A), drilled from early May to late August 2014. It sampled a thick section of the lower part of the Seve Complex and was planned to penetrate its basal thrust zone into the underlying lower grade metamorphosed allochthon. The drill hole reached a depth of 2495.8 m and nearly 100 % core recovery was achieved. Although planning was based on existing geological mapping and new high‐resolution seismic surveys, the drilling resulted in some surprises: the Lower Seve Nappe proved to be composed of rather homogenous gneisses, with only subordinate mafic bodies and its basal thrust zone was unexpectedly thick (〉 800 m). The drill hole did not penetrate the bottom of the thrust zone. However, lower grade metasedimentary rocks were encountered in the lowermost part of the drill hole together with garnetiferous mylonites tens of metres thick. The tectonostratigraphic position is still unclear and geological and geophysical interpretations are under revision. The compact gneisses host only 8 fluid conducting zones of limited transmissivity between 300 m and total depth. Downhole measurements suggest an uncorrected average geothermal gradient of ~20°C/km. The drill core was documented on‐site and XRF scanned off site. During various stages of the drilling, the borehole was documented by comprehensive downhole logging. This operational report provides an overview over the COSC‐1 operations from drilling preparations to the sampling party and describes the available datasets and sample material.

    Description: Today more than 45 % of all energy-related CO2 emissions come from burning coal. Thus, reducing CO2 emissions from coal use is a necessity for reaching the targets of the Paris Agreement. This will not only pose challenges for coal consumers (restructuring of the energy system), but also for countries whose economy is strongly depending on the production of coal. This paper examines the role of coal in three countries, which are or were in recent years among the top coal exporters: Indonesia, Colombia and Vietnam. Understanding challenges and possible transition pathways in these countries will help to develop global strategies to reduce CO2 emissions from coal in the short to mid-term.

    Description: The Pacific region of Colombia, like many sparsely populated places in developing countries, has been imagined as empty in social terms, and yet full in terms of natural resources and biodiversity. These imaginaries have enabled the creation of frontiers of land and sea control, where the state as well as private and illegal actors have historically dispossessed Afro-descendant and indigenous peoples. This paper contributes to the understanding of territorialisation in the oceans, where political and legal framings of the sea as an open-access public good have neglected the existence of marine social processes. It shows how Afro-descendant communities and non-state actors are required to use the language of resources, rather than socio-cultural attachment, to negotiate state marine territorialisation processes. Drawing on a case study on the Pacific coast of Colombia, we demonstrate that Afro-descendant communities hold local aquatic epistemologies, in which knowledge and the production of space are entangled in fluid and volumetric spatio-temporal dynamics. However, despite the social importance of aquatic environments, they were excluded from Afro-descendants' collective territorial rights in the 1990s. Driven by their local aquatic epistemologies, coastal communities are reclaiming authority over the seascape through the creation of a marine protected area. We argue that they have transformed relations of authority at sea to ensure local access and control, using state institutional instruments to subvert and challenge the legal framing of the sea as an open access public good. As such, this marine protected area represents a place of resistance that ironically subjects coastal communities to disciplinary technologies of conservation.
