    A major sustainability challenge is determining where to target management to enhance natural capital and the ecosystem services it provides. Achieving this understanding is difficult, given that the effects of most actions vary according to wider environmental conditions; and this context dependency is typically poorly understood. Here, we describe an analytical framework that helps meet this challenge by identifying both why and where management actions are most effective for enhancing natural capital across large geographic areas. We illustrate the framework’s generality by applying it to two examples for Britain: pond water quality and invasion of forests by rhododendron

    Effective surface albedo due to snow cover of the surrounding area

    Albedo inversion techniques are investigated in this work. Several methods are applied to spectral irradiance data from a measurement campaign held in the German Alps during the spring of 1999. One first method is based on the comparison of measurements of absolute levels of UV irradiance with model calculations. The second method takes advantage of changes in the spectral slope of spectral UV irradiance, which is a function of the surface albedo. In the third method, the surrounding area is partitioned into snow-covered and snow-free regions, and the effective albedo estimated by applying a higher or lower reflectivity to each facet before integrating over the surroundings. We present sensitivity analysis, the differences and the correlations between the various methods as well as the results for the different locations

    Assessing Butterflies in Europe. Executive summary

    Get PDF
    1. The Assessing Butterflies in Europe (ABLE) project was an EU Parliamentary Pilot project with a duration of two years (beginning of December 2019 to the end of November 2020) and received €800,000 of funding via a service contract with Directorate General Environment. 2. The mandate and rationale from the EU Parliament was: “The project aims at developing a suite of EU Lepidoptera indicators which can help improve conservation measure and assess progress in implementing EU policies and legislation such as the EU Biodiversity Strategy to 2020 and the EU Habitats Directive. Besides providing a highly relevant indicator for measuring progress in terms of managing and restoring Natura 2000 sites, it would also contribute to monitoring progress on Target 3 of the EU Biodiversity Strategy, which aims to increase the contribution of agriculture and forestry to maintaining and enhancing biodiversity. In particular, the pilot should deliver a representative indicator to help monitor the impact of the Common Agricultural Policy on grassland biodiversity. It will also provide data to produce a climate change indicator, thereby contributing to the ongoing revision of climate change adaptation strategies. Indicators will also be possible for woodland, wetland and urban habitats.” 3. The ABLE project was delivered by a consortium of the UK Centre for Ecology & Hydrology, Butterfly Conservation Europe, Butterfly Conservation UK, De Vlinderstichting and HelmholtzZentrum fĂŒr Umweltforschung GmbH – UFZ. Considerable in-kind contributions were provided by Butterfly Conservation partners across Europe. 4. There is mounting evidence of widespread declines in the diversity and abundance of insects across the globe. The ABLE project is particularly timely in helping to develop capacity for monitoring of insects and assessing the status of butterflies in the EU. 5. There are 482 butterfly species in Europe (451 occurring within the EU27), breeding in a wide range of habitats. Butterflies react quickly to change and are considered to be good biological indicators, especially of other insects and pollinators. Monitoring butterflies can help shed light on changes in these important groups. 6. The main aims of the ABLE project were to collate butterfly monitoring data across Europe, to facilitate the start of new schemes in the EU, and to develop indicators to help policy design and evaluation. 7. Following the mandate from the EU Parliament for this Pilot project, we make the following key recommendations: i. Use Butterfly Monitoring Scheme (eBMS) data and indicators for EU policy design; to inform resource planning, especially for Member State’s Prioritised Action Frameworks (PAFs); and to track, evaluate and adjust EU and MSs policy implementation, including the EU Green Deal, EU Biodiversity Strategy 2030 and the EU Farm to Fork Strategy, to help reverse pollinator declines. ii. Use Member State and Article 17 data on butterflies to inform the design, implementation and evaluation of the EU CAP and MS’s CAP Strategic Plans; to ensure Forestry plans include more grassland refuges and herb rich rides and edges; and that urban planning and regional developments invest in pollinator habitats. Butterfly Conservation Europe 2020 \textbar ASSESSING BUTTERFLIES IN EUROPE – EXECUTIVE SUMMARY 6 iii. Use available Butterfly Monitoring Scheme data to strengthen the quality of assessments of conservation Status of Habitats Directive listed habitats and species in meeting mandatory reporting requirements under Art 17 of the Directive iv. Invest in linking butterfly data with land use and management data, including implementation of Natura 2000 Management Plans, Land Parcel Information system and Satellite data to help evaluate conservation effectiveness v. Support additional monitoring of rare and vulnerable butterflies (including endemics and those not listed on the Habitats Directive) and designate some additional Protected Areas to sustain and enhance the quality of remaining areas that are important for these Red Listed butterflies and so prevent further extinctions vi. Invest in further capacity building and cooperation among citizen scientists, professionals, farmers and authorities to monitor and record abundance of butterflies, moths and other pollinators, including supporting coordination, training and growth of citizen science eBMS schemes (as recommended by EU Pollinator Expert Group); filling data gaps and developing tools and expertise to gather and integrate data from various sources. vii. ABLE shows that Citizen Science eBMS are cost effective, delivering very good value for money. New citizen science Butterfly Monitoring Schemes are needed in Denmark, Greece, Latvia, Romania and Slovakia. Together with further support to sustain and increase transects across most EU MSs, especially in the ten schemes newly created during the ABLE project. The ten EU27 countries where new Citizen Science butterfly monitoring schemes were begun in 2019/2020, with the support of ABLE, BCE partners and active volunteers, are Austria, Bulgaria, Croatia, Cyprus, Czech Republic, Hungary, Italy, Malta, Poland and Portugal. Together with Belgium, Estonia, Finland, France, Germany, Ireland, Luxemburg, Lithuania (currently dormant), Netherlands, Slovenia, Spain, Sweden, there are now 22 EU(27) Member States with butterfly monitoring schemes. With several more outside the EU, including Norway, Switzerland and the UK (which has the longest running scheme). 8. This Executive Summary accompanies detailed technical reports on the three project tasks: development of butterfly indicators, development of butterfly monitoring networks, and tools to support butterfly monitoring and analysis

    The National Plant Monitoring Scheme: a technical review

    Get PDF
    The National Plant Monitoring Scheme, coordinated by the Botanical Society of Britain and Ireland, the Centre for Ecology & Hydrology, JNCC and Plantlife, was launched in 2015 to provide an indication of the status and trends of plants and semi-natural habitats across the UK. The scheme is based on volunteer recording according to a set protocol at pre-determined monads selected through a weighted-random sampling scheme

    Rewiring of interactions in a changing environment: nettle‐feeding butterflies and their parasitoids

    Climate and land use change can alter the incidence and strength of biotic interactions, with important effects on the distribution, abundance and function of species. To assess the importance of these effects and their dynamics, studies quantifying how biotic interactions change in space and time are needed. We studied interactions between nettle‐feeding butterflies and their shared natural enemies (parasitoids) locally and across 500 km latitudinal gradient in Sweden. We also examined the potential impact of the range‐expansion of the butterfly Araschnia levana on resident butterflies via shared parasitoids, by studying how parasitism in resident butterflies covaries with the presence or absence of the newly‐established species. We collected 6777 larvae of four nettle‐feeding butterfly species (Aglais urticae, Aglais io, Ar. levana and Vanessa atalanta), over two years, at 19 sites distributed along the gradient. We documented the parasitoid complex for each butterfly species and measured their overlap, and analysed how parasitism rates were affected by butterfly species assemblage, variations in abundance, time, and the arrival of Ar. levana. Parasitoids caused high mortality, with substantial overlap in the complex of parasitoids associated with the four host butterflies. Levels of parasitism differed significantly among butterflies and were influenced by the local butterfly species assemblage. Our results also suggest that parasitism in resident butterflies is elevated at sites where Ar. levana has been established for a longer period. In our study system, variations in butterfly species assemblages were associated in a predictable way with substantial variations in rates of parasitism. This relationship is likely to affect the dynamics of the butterfly host species, and potentially cascade to the larger number of species with which they interact. These results highlight the importance of indirect interactions and their potential to reorganise ecological communities, especially in the context of shifts in species distributions in a warmer world

    HtrA1 Mediated Intracellular Effects on Tubulin Using a Polarized RPE Disease Model

    Age-related macular degeneration (AMD) is the leading cause of irreversible vision loss. The protein HtrA1 is enriched in retinal pigment epithelial (RPE) cells isolated from AMD patients and in drusen deposits. However, it is poorly understood how increased levels of HtrA1 affect the physiological function of the RPE at the intracellular level. Here, we developed hfRPE (human fetal retinal pigment epithelial) cell culture model where cells fully differentiated into a polarized functional monolayer. In this model, we fine-tuned the cellular levels of HtrA1 by targeted overexpression. Our data show that HtrA1 enzymatic activity leads to intracellular degradation of tubulin with a corresponding reduction in the number of microtubules, and consequently to an altered mechanical cell phenotype. HtrA1 overexpression further leads to impaired apical processes and decreased phagocytosis, an essential function for photoreceptor survival. These cellular alterations correlate with the AMD phenotype and thus highlight HtrA1 as an intracellular target for therapeutic interventions towards AMD treatment

    Binding to SMN2 pre-mRNA-protein complex elicits specificity for small molecule splicing modifiers

    Small molecule splicing modifiers have been previously described that target the general splicing machinery and thus have low specificity for individual genes. Several potent molecules correcting the splicing deficit of the SMN2 (survival of motor neuron 2) gene have been identified and these molecules are moving towards a potential therapy for spinal muscular atrophy (SMA). Here by using a combination of RNA splicing, transcription, and protein chemistry techniques, we show that these molecules directly bind to two distinct sites of the SMN2 pre-mRNA, thereby stabilizing a yet unidentified ribonucleoprotein (RNP) complex that is critical to the specificity of these small molecules for SMN2 over other genes. In addition to the therapeutic potential of these molecules for treatment of SMA, our work has wide-ranging implications in understanding how small molecules can interact with specific quaternary RNA structures

    Can we model cultural ecosystem services, and are we measuring the right things?

    Abstract: Cultural ecosystem services (CES), a key aspect of nature's contributions to people, remain a challenge to incorporate into decision making. One contributing factor is the difficulty of defining and describing these, due partly to: ongoing poor understanding of what drives people to interact with nature, a lack of appropriate data to quantify these interactions, and basic difficulties in measuring and modelling the complex array of social, psychological and behavioural attributes which help explain people's actions. In this study we present a framework which develops the concepts of cultural capital, social capital and human capital as specific forms of human‐centred capital, in the context of their contribution to understanding CES. Each form of capital encompasses separate attributes of beneficiaries. Testing the framework with data from a separate trans‐disciplinary study illustrated that the framework was readily applicable to specific situations. A measure of cultural capital, EcoCentrism, explained more variation than a suite of seven demographic variables. Applying the framework also showed that despite using a wide range of explanatory variables, a large proportion of observed variation remained unaccounted for. This suggests that more work is needed to understand and to develop metrics which can measure additional factors which underlie peoples’ motivations to engage with nature. The framework is applicable to other types of ecosystem service, and may also be useful for exploring relational values.
