Aim: Experimental nitrogen (N) addition (fertilization) studies are commonly used to quantify the impacts of increased N inputs on plant biodiversity. However, given that plant community responses can vary considerably among individual studies, there is a clear need to synthesize and generalize findings with meta-analytical approaches. Our goal was to quantify changes in species richness and abundance in plant communities in response to N addition across different environmental contexts, while controlling for different experimental designs. Location: Global. Time period: Data range: 1985–2016; Publication years: 1990–2018. Major taxa studied: Plants. Methods: We performed a meta-analysis of 115 experiments reported in 85 studies assessing the effects of N addition on terrestrial natural and semi-natural plant communities. We quantified local-scale changes in plant biodiversity in relationship to N addition using four metrics: species richness (SR), individual species abundance (IA), mean species abundance (MSA) and geometric mean abundance (GMA). Results: For all metrics, greater amounts of annual N addition resulted in larger declines in plant diversity. Additionally, MSA decreased more steeply with N that was applied in reduced (NH4 +) rather than oxidized ((NO 3)) form. Loss of SR with increasing amounts of N was found to be larger in warmer sites. Furthermore, greater losses of SR were found in sites with longer experimental durations, smaller plot sizes and lower soil cation exchange capacity. Finally, reductions in the abundance of individual species were larger for N-sensitive plant life-form types (legumes and non-vascular plants). Main conclusions: N enrichment decreases both SR and abundance of plants in N-addition experiments, but the magnitude of the response differs among biodiversity metrics and with the environmental and experimental context. This underlines the importance of integrating multiple dimensions of biodiversity and relevant modifying factors into assessments of biodiversity responses to global environmental change.

To support the assessments of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), the IPBES Expert Group on Scenarios and Models is carrying out an intercomparison of biodiversity and ecosystem services models using harmonized scenarios (BES-SIM). The goals of BES-SIM are (1) to project the global impacts of land-use and climate change on biodiversity and ecosystem services (i.e., nature's contributions to people) over the coming decades, compared to the 20th century, using a set of common metrics at multiple scales, and (2) to identify model uncertainties and research gaps through the comparisons of projected biodiversity and ecosystem services across models. BES-SIM uses three scenarios combining specific Shared Socio-economic Pathways (SSPs) and Representative Concentration Pathways (RCPs)-SSP1xRCP2.6, SSP3xRCP6.0, SSP5xRCP8.6-to explore a wide range of land-use change and climate change futures. This paper describes the rationale for scenario selection, the process of harmonizing input data for land use, based on the second phase of the Land Use Harmonization Project (LUH2), and climate, the biodiversity and ecosystem services models used, the core simulations carried out, the harmonization of the model output metrics, and the treatment of uncertainty. The results of this collaborative modeling project will support the ongoing global assessment of IPBES, strengthen ties between IPBES and the Intergovernmental Panel on Climate Change (IPCC) scenarios and modeling processes, advise the Convention on Biological Diversity (CBD) on its development of a post-2020 strategic plans and conservation goals, and inform the development of a new generation of nature-centred scenarios.

The morphology of the digital pads of tree frogs is adapted towards attachment, allowing these animals to attach to various substrates and to explore their arboreal habitat. Previous descriptions and functional interpretations of the pad morphology mostly focussed on the surface of the ventral epidermis, and little is known about the internal pad morphology and its functional relevance in attachment. In this study, we combine histology and synchrotron micro-computer-tomography to obtain a comprehensive 3-D morphological characterisation of the digital pads (in particular of the internal structures involved in the transmission of attachment forces from the ventral pad surface towards the phalanges) of the tree frog Hyla cinerea. A collagenous septum runs from the distal tip of the distal phalanx to the ventral cutis and compartmentalises the subcutaneous pad volume into a distal lymph space and a proximal space, which contains mucus glands opening via long ducts to the ventral pad surface. A collagen layer connects the ventral basement membrane via interphalangeal ligaments with the middle phalanx. The collagen fibres forming this layer curve around the transverse pad-axis and form laterally separated ridges below the gland space. The topological optimisation of a shear-loaded pad model using finite element analysis (FEA) shows that the curved collagen fibres are oriented along the trajectories of the maximum principal stresses, and the optimisation also results in ridge-formation, suggesting that the collagen layer is adapted towards a high stiffness during shear loading. We also show that the collagen layer is strong, with an estimated tensile strength of 2.0–6.5 N. Together with longitudinally skewed tonofibrils in the superficial epidermis, these features support our hypothesis that the digital pads of tree frogs are primarily adapted towards the generation and transmission of friction rather than adhesion forces. Moreover, we generate (based on a simplified FEA model and predictions from analytical models) the hypothesis that dorsodistal pulling on the collagen septum facilitates proximal peeling of the pad and that the septum is an adaptation towards detachment rather than attachment. Lastly, by using immunohistochemistry, we (re-)discovered bundles of smooth muscle fibres in the digital pads of tree frogs. We hypothesise that these fibres allow the control of (i) contact stresses at the pad–substrate interface and peeling, (ii) mucus secretion, (iii) shock-absorbing properties of the pad, and (iv) the macroscopic contact geometry of the ventral pad surface. Further work is needed to conclude on the role of the muscular structures in tree frog attachment. Overall, our study contributes to the functional understanding of tree frog attachment, hence offering novel perspectives on the ecology, phylogeny and evolution of anurans, as well as the design of tree-frog-inspired adhesives for technological applications.

Herkomtst nutriënten Alblasserwaard en Vijfheerenlanden

Wageningen : Wageningen Environmental Research (Wageningen Environmental Research rapport 2891) - 61
De regionale waterkwaliteit voldoet op veel plaatsen nog niet aan de doelen die voor de Europese Kaderrichtlijn Water zijn gesteld. Een belangrijke oorzaak hiervan is de hoge nutriëntenbelasting. Het generieke mestbeleid zal naar verwachting niet voor 2027 leiden tot de voor de ecologie gewenste verlaging van nutriëntenbelasting. In de Stroomgebiedsbeheerplannen voor de 3e periode (2022-2027) moet Nederland de definitieve keuzes maken over de doelen van de waterlichamen en in te zetten maatregelen. Met name voor de waterlichamen in de Alblasserwaard (Nederwaard en Overwaard) wil Waterschap Rivierenland bij het definitief vaststellen van de doelen en maatregelen goed rekening kunnen houden met de achtergrondbelasting door nutriëntenrijke kwel, stikstofdepositie, mineralisatie en uitloging van veenbodems. In dit onderzoek is de nutriëntenbelasting voor de periode 2004-2013 gekwantificeerd voor de
Nederwaard, Overwaard en het aangrenzende afwateringsgebied vijfheerenlanden. Met de methodiek ECHO zijn voor het kwantificeren van de uit- en afspoeling van nutriënten de rekenplots van het landelijk modelinstrumentarium STONE regiospecifieker toebedeeld op basis van actuele informatie over het landgebruik, bodemtype en de grondwaterstanden. Per gebied zijn de hoeveelheden inlaatwater en uitgemalen water gekwantificeerd (watervolume en nutriëntenvrachten) op basis van de meetdata en regiospecifieke kennis die het Waterschap voor het onderzoek heeft aangedragen. De belasting met nutriënten vanuit overige bronnen zijn ontleend aan de EmissieRegistratie. Na kwantificering en validatie van de berekende waterbalansen en nutriëntenbalansen is de belasting onderverdeeld naar de bronnen van herkomst. Uit het onderzoek blijkt dat de totale nutriëntenbelasting van het oppervlaktewater voornamelijk wordt bepaald door de uit- en afspoeling uit landbouwgronden (83 à 95%). Voor stikstof levert de actuele bemesting het grootste aandeel (Nederwaard 38%, Overwaard 42%, Vijfheerenlanden 55%), gevolgd door de nalevering vanuit landbouwgronden (respectievelijk 20%, 17% en 8%). Met het modelinstrumentarium zijn de effecten van het 5e Nitraat Actie Programma op de uit- en afspoeling van nutriënten berekend. Evenals de landelijke evaluatie komt hieruit naar voren dat het effect hiervan op de nutriëntenbelasting in de beschouwde gebieden gering is (kleiner dan 5%).

In a recent large-scale prevalence study of interpersonal violence (IV) against child athletes in the Netherlands and Belgium we found that 9% of adult respondents who participated in organized sports before the age of 18 had experienced severe psychological violence, 8% severe physical violence, and 6% severe sexual violence in various sport settings. While the general literature has repeatedly shown that exposure to IV during childhood is associated with mental health problems in adulthood and to a lesser extent with reduced quality of life (QOL), these relationships have not been demonstrated in (former) athletes. Thus, the current study aims to assess the association of severe childhood IV in sport and adult wellbeing. Depression, anxiety, and somatization were assessed in the same general population sample (N = 4043) using the Brief Symptom Inventory (BSI-18) and QOL with the World Health Organization Quality of Life questionnaire (WHOQOL-Brèf). The association between severe IV in sport and adult wellbeing was investigated using multiple linear regression while controlling for demographics, recent life events, and relatives’ psychological problems. We found severe sexual, physical, and psychological childhood IV in sport to be associated with more adult psychological distress and reduced QOL. Polyvictimization shows the strongest correlation with poorer wellbeing and QOL. Recent life events, relatives’ psychological problems, marital status, and level of education were significant covariates in the psychological symptoms and QOL assessed. We hope that these new insights prompt sport administrators to implement broad spectrum child protection measures and raise the awareness of mental health professionals about the necessity to also screen for adverse childhood experiences in the sport context.

Best-response potential games - Location games - Pure Nash equilibrium existence - Symmetric games
We revisit two-person one-dimensional pure location games à la Anderson et al. (1992) and show that they admit continuous best-response potential functions (Voorneveld, 2000) if demand is sufficiently elastic (to the extent that the Principle of Minimum Differentiation fails); if demand is not that elastic (or is completely inelastic) they still admit continuous quasi-potential functions (Schipper, 2004). We also show that, even if a continuous best-response potential function exists, a generalized ordinal potential function (Monderer and Shapley, 1996) need not exist.
Kansen voor meer natuurlijkheid in Natura 2000-gebieden

Aan alle Natura 2000-gebieden zijn instandhoudingsdoelstellingen toegewezen voor soorten en/of habitattypen
van de Vogel- en Habitatrichtlijn. De bezorgdheid groeit dat beheerplannen te weinig rekening
houden met noodzakelijke natuurlijke dynamiek en uitwijkmogelijkheden voor soorten. En hoe staat het
met andere natuurwaarden? Een expliciete landschapsecologische benadering biedt uitkomst en kan goed
aansluiten op het beheerplanproces en richtlijnen bieden voor vergunningverlening en handhaving.
