Conserving and managing global natural capital requires an understanding of the complexity of flows of ecosystem services across geographic boundaries. Failing to understand and to incorporate these flows into national and international ecosystem assessments leads to incomplete and potentially skewed conclusions, impairing society's ability to identify sustainable management and policy choices. In this paper, we synthesise existing knowledge and develop a conceptual framework for analysing interregional ecosystem service flows. We synthesise the types of such flows, the characteristics of sending and receiving socio-ecological systems, and the impacts of ecosystem service flows on interregional sustainability. Using four cases (trade of certified coffee, migration of northern pintails, flood protection in the Danube watershed, and information on giant pandas), we test the conceptual framework and show how an enhanced understanding of interregional telecouplings in socio-ecological systems can inform ecosystem service-based decision making and governance with respect to sustainability goals.
Monoterpene chemical speciation in a tropical rainforest : variation with season, height, and time of dayat the Amazon Tall Tower Observatory (ATTO)

Speciated monoterpene measurements in rainforest air are scarce, but they are essential for understanding the contribution of these compounds to the overall reactivity of volatile organic compound (VOC) emissions towards the main atmospheric oxidants, such as hydroxyl radicals (OH), ozone (O3) and nitrate radicals (NO3). In this study, we present the chemical speciation of gas-phase monoterpenes measured in the tropical rainforest at the Amazon Tall Tower Observatory (ATTO, Amazonas, Brazil). Samples of VOCs were collected by two automated sampling systems positioned on a tower at 12 and 24ĝ€-m height and analysed using gas chromatography-flame ionization detection. The samples were collected in October 2015, representing the dry season, and compared with previous wet and dry season studies at the site. In addition, vertical profile measurements (at 12 and 24ĝ€-m) of total monoterpene mixing ratios were made using proton-transfer-reaction mass spectrometry. The results showed a distinctly different chemical speciation between day and night. For instance, α-pinene was more abundant during the day, whereas limonene was more abundant at night. Reactivity calculations showed that higher abundance does not generally imply higher reactivity. Furthermore, inter- and intra-annual results demonstrate similar chemodiversity during the dry seasons analysed. Simulations with a canopy exchange modelling system show simulated monoterpene mixing ratios that compare relatively well with the observed mixing ratios but also indicate the necessity of more experiments to enhance our understanding of in-canopy sinks of these compounds.

Tannins and soybean oil are available as feed supplement to ruminants in the semi-arid region of Brazil and potentially change the degradability of nutrients and gas production. The aim of this study was to evaluate the influence of diets with condensed tannin (CT) and soybean oil (SBO) supplementation on in vitro gas production, degradability and ruminal fermentation characteristics. The inclusion of CT and SBO replaced equal amount of concentrate in dry matter basis. Treatments were T1 = 60% elephant grass + 40% concentrate (control); T2 = 60% elephant grass + 37% concentrate + 3% CT (Weibull); T3 = 60% elephant grass + 35% concentrate + 5% SBO; T4 = 60% elephant grass + 32% concentrate + 3% CT (Weibull) + 5% SBO. The gas production was decreased with inclusion of CT (104 ml g-1) and SBO (111 ml g-1), with significant interaction between the two supplements (99 ml g-1) compared to control (128 ml g-1). The effective DM degradability was also reduced to inclusion of CT (31.0%) and CT-SBO (33.8%) compared to control (38.4%). The potential degradability of CP was lower due to SBO (73.5%) and CT-SBO (80.3%) inclusion, but higher in NDF potential degradability (71.4%) than control treatment (84.9% to CP and 63.8% to NDF). In terms of effective degradability, CT was the supplement which presented most regular pattern to decrease the degradability of DM, CP and NDF. The effective interaction of supplements is dependent on the type of the nutritional parameter under evaluation. The SBO was the supplement with wider effect on ruminal fermentation, increasing the pH (6.58 vs. 6.50) and NH3-N (19.5 vs 13.9 ml l-1 of rumen liquid) in comparison to control. The supplements can be regarded as effectives to control the degradability of nutrients and gas production.

Effect of the material properties on the crumpling of a thin sheet
Habibi, Mehdi ; Adda-Bedia, Mokhtar ; Bonn, Daniel - \ 2017
Soft Matter 13 (2017)22. - ISSN 1744-683X - p. 4029 - 4034.

While simple at first glance, the dense packing of sheets is a complex phenomenon that depends on material parameters and the packing protocol. We study the effect of plasticity on the crumpling of sheets of different materials by performing isotropic compaction experiments on sheets of different sizes and elasto-plastic properties. First, we quantify the material properties using a dimensionless foldability index. Then, the compaction force required to crumple a sheet into a ball as well as the average number of layers inside the ball are measured. For each material, both quantities exhibit a power-law dependence on the diameter of the crumpled ball. We experimentally establish the power-law exponents and find that both depend nonlinearly on the foldability index. However the exponents that characterize the mechanical response and morphology of the crumpled materials are related linearly. A simple scaling argument explains this in terms of the buckling of the sheets, and recovers the relation between the crumpling force and the morphology of the crumpled structure. Our results suggest a new approach to tailor the mechanical response of the crumpled objects by carefully selecting their material properties.

Compaction of quasi-one-dimensional elastoplastic materials
Reza Shaebani, M. ; Najafi, Javad ; Farnudi, Ali ; Bonn, Daniel ; Habibi, Mehdi - \ 2017

Insight into crumpling or compaction of one-dimensional objects is important for understanding biopolymer packaging and designing innovative technological devices. By compacting various types of wires in rigid confinements and characterizing the morphology of the resulting crumpled structures, here, we report how friction, plasticity and torsion enhance disorder, leading to a transition from coiled to folded morphologies. In the latter case, where folding dominates the crumpling process, we find that reducing the relative wire thickness counter-intuitively causes the maximum packing density to decrease. The segment size distribution gradually becomes more asymmetric during compaction, reflecting an increase of spatial correlations. We introduce a self-Avoiding random walk model and verify that the cumulative injected wire length follows a universal dependence on segment size, allowing for the prediction of the efficiency of compaction as a function of material properties, container size and injection force.

Nederland is Party van ‘the Agreement on the Conservation of Populations of European Bats’, ofwel EUROBATS. De EUROBATS-agreement is een verdrag onder de conventie van Bern en met name de conventie van Bonn, de ‘Convention on the Conservation of Migratory Species of Wild Animals’. EUROBATS is een instrument bij de uitvoering van de verplichtingen vanuit de Europese Habitatrichtlijn. De Scientific Advisory Committee ontwikkelt resoluties, welke door de overheden van de Party-States van de EUROBATS-Agreement gezamenlijk worden aangenomen. Deze resoluties benoemen – specifiek vanuit de ecologie van de vleermuizen – knelpunten, speciale aandachtspunten en kansen, welke helpen de uitvoering van wet- en regelgeving in het kader van de Flora- en faunawet en Habitatrichtlijn effectief te focussen. De voorliggende rapportage geeft een overzicht van de resoluties en maakt inzichtelijk wat de Rijksoverheid, provincies of andere organisaties reeds doen voor vleermuizen. Tevens is een kennisagenda opgenomen met aanbevelingen ten behoeve van vleermuizen voor de nabije toekomst.
