  • Microbiome composition of disturbed soils from sandy-gravel mining
           complexes with different reclamation approaches

    • Abstract: One Ecosystem 7: e83756
      DOI : 10.3897/oneeco.7.e83756
      Authors : Anastasiia Kimeklis, Grigory Gladkov, Rustam Tembotov, Arina Kichko, Alexander Pinaev, Sergey Hosid, Evgeny Andronov, Evgeny Abakumov : Activities connected to mineral mining disrupt the soil layer and bring parent rock material to the surface. It leads to altering the environmental conditions and leaves behind vast areas of disturbed lands. Returning these lands to natural ecosystems is an important contemporary challenge, which can be acquired by reclamation practices. Soil microbiome composition reflects changes happening to disturbed lands; thus, its analysis is a powerful tool for evaluating the disturbance degree and estimating the effect of the implementation of reclamation techniques. Additionally, factors connected to the characteristics of a particular geographical region have a certain impact on the microbiome and should be taken into account. Thereby, studies of soil microbiomes of disturbed soils of different origins are essential in understanding the dynamics of soil restoration. Here, we focus on soil microbiomes from two sandy-gravel mining complexes in mountainous areas with a moderate continental climate of the Central Caucasus. These quarries share the same parent rock material, but differ in benchmark soil type and reclamation approach - one was left for passive recovery and the other was technically reclaimed with overburden material. Comparative analysis of microbiome composition, based on sequencing of 16S rRNA gene libraries, showed that region and disturbance are the key factors explaining microbiome variation, which surpass the influence of local factors. However, the application of reclamation techniques greatly reduces the dissimilarity of soil microbiomes caused by disturbance. Linking of soil chemical parameters to microbiome composition showed that the disturbance factor correlates with a lack of organic carbon. Other chemical parameters, like pH, ammonium, nitrates and total carbon explain microbiome variability on a smaller scale between sampling sites. Thus, while regional and disturbance factors reflected differentiation of soil microbiomes, soil chemical parameters explained local variation of certain groups of microorganisms. HTML XML PDF

  • Ecosystem condition underpins the generation of ecosystem services: an
           accounting perspective

    • Abstract: One Ecosystem 7: e81487
      DOI : 10.3897/oneeco.7.e81487
      Authors : Alessandra La Notte, Bálint Czúcz, Sara Vallecillo, Chiara Polce, Joachim Maes : There is a linkage between the condition of ecosystems and the services they provide. In the accounting framework set by the United Nations System of integrated Environmental Economic Accounting – Ecosystem Accounts (SEEA EA), two different sets of accounts assess and monitor ecosystem condition and ecosystem services, respectively. The former are reported as indicators in an asset account format, while the latter are reported as supply and use tables. Without a concrete linkage, the two sets of accounts run in parallel: only an ex-post correlation analysis could confirm (or not) a common path. On the other hand, a clear linkage could create a sequence that justifies and supports the statement that any change in ecosystem condition will affect services and, in turn, the benefits provided to economy and society. Concrete applications undertaken under the project “Integrated system for Natural Capital Accounts” demonstrate at which stage a direct connection can occur between ecosystem condition and ecosystem services accounting. The paper starts with a theoretical background meant to set the basic concepts underlying the transition from condition to services. Next, the accounting framework for condition accounts is briefly presented: the specific ecosystem services case studies concern flood control and crop pollination. In the discussion, a simple proposal is drafted to facilitate a possible procedure for those practitioners interested in having condition and ES accounts operationally linked. HTML XML PDF

  • Approach to user group-specific assessment of urban green spaces for a
           more equitable supply exemplified by the elderly population

    • Abstract: One Ecosystem 7: e83325
      DOI : 10.3897/oneeco.7.e83325
      Authors : Celina Stanley, Robert Hecht, Sercan Cakir, Patrycia Brzoska : The use of urban green spaces (UGS) depends on its quality, which is perceived very differently by diverse socio-demographic groups. In particular, elderly people have special demands on the UGS quality. It is essential to know these demands to create an equitable UGS supply. We present an approach to determining some qualitative aspects and the supply of cultural ecosystem services of diverse forms of UGS. This is realised by combining user demands with actual UGS features. In a concrete example, we assessed the UGS quality and supply for both the general population and the subset of elderly people. For the latter group, the activities of relaxing and observing nature, as well as the UGS feature of benches, were found to be significantly more important than for the general population. Nevertheless, this had only a minor impact on the assessed aspects of UGS quality and supply, with little differences detected between the two groups. In Dresden (Germany), we determined that almost half of the elderly population are not provided with high-quality UGS. In these areas, urban planning must increase the UGS quality while taking user demands into account to ensure just access to the positive benefits of UGS for the elderly. HTML XML PDF

  • Assessing ecosystem condition at the national level in Hungary -
           indicators, approaches, challenges

    • Abstract: One Ecosystem 7: e81543
      DOI : 10.3897/oneeco.7.e81543
      Authors : Eszter Tanács, Ákos Bede-Fazekas, Anikó Csecserits, Lívia Kisné Fodor, László Pásztor, Imelda Somodi, Tibor Standovár, András Zlinszky, Zita Zsembery, Ágnes Vári : The availability of robust and reliable spatial information on ecosystem condition is of increasing importance in informing conservation policy. Recent policy requirements have sparked a renewed interest in conceptual questions related to ecosystem condition and practical aspects like indicator selection, resulting in the emergence of conceptual frameworks, such as the System of Environmental-Economic Accounting - Ecosystem Accounting (SEEA-EA) and its Ecosystem Condition Typology (ECT). However, while such frameworks are essential to ensure that condition assessments are comprehensive and comparable, large-scale practical implementation often poses challenges that need to be tackled within stringent time and cost frames.We present methods and experiences of the national-level mapping and assessment of ecosystem condition in Hungary. The assessments covered the whole country, including all major ecosystem types present. The methodology constitutes four approaches of quantifying and mapping condition, based on different interpretations of naturalness and hemeroby, complemented by two more using properties that ‘overarch’ ecosystem types, such as soil and landscape attributes. In order to highlight their strengths and drawbacks, as well as to help reconcile aspects of conceptual relevance with practical limitations, we retrospectively evaluated the six mapping approaches (and the resulting indicators) against the indicator selection criteria suggested in the SEEA-EA. The results show that the various approaches have different strengths and weaknesses and, thus, their joint application has a higher potential to address the specific challenges related to large-scale ecosystem condition mapping.

  • Guidelines and a supporting toolbox for parameterising key soil hydraulic
           properties in hydrological studies and broader integrated modelling

    • Abstract: One Ecosystem 7: e76410
      DOI : 10.3897/oneeco.7.e76410
      Authors : Nguyet Dang, Bethanna Jackson, Stephanie Tomscha, Linda Lilburne, Kremena Burkhard, Dung Duc Tran, Long Phi, Rubianca Benavidez : Information on soil hydraulic properties (e.g. soil moisture pressure relationships and hydraulic conductivity) is valuable for a wide range of disciplines including hydrology, ecology, environmental management and agriculture. However, this information is often not readily available as direct measurements are costly and time-consuming. Furthermore, as more complex representations of soils are being built into environmental models, users and developers often require sound hydraulic property information, while having limited access to specialist knowledge. Although indirect methods have been developed to obtain soil hydraulic properties from easily measurable or readily available soil properties via pedo-transfer functions (PTFs), few articles provide guidance for obtaining soil hydraulic properties over a wide range of geoclimatic and regional data availability contexts. The aim of this study is, therefore, to develop guidelines and an associated spatially referenced toolbox, NB_PTFs, to speed the process of acquiring sensible soil hydraulic properties for different geoclimatic and data-rich/sparse regions. The guide compiles available information about soil hydraulic properties, as well as a large number (151) of PTFs, not collated in any other guidance to date. NB_PTFs is an open-source ArcGIS toolbox which allows users to quickly get values, graphs and spatial distributions of soil hydraulic properties. The soil hydraulic properties, obtained using the guide and the toolbox, can be used as inputs for various models amongst other purposes. To demonstrate the use of the guidelines and the toolbox in different geoclimatic and data-availability contexts, the paper presents two case studies: the Vietnamese Mekong Delta and New Zealand Hurunui catchment. The Vietnamese Mekong Delta shows the use of these guidelines in a tropical, flat location with limited information on soil physical, chemical and hydraulic properties. The Hurunui catchment represents a case study for a semi-arid and hilly area in an area with detailed soil information. HTML XML PDF

  • Green balance in urban areas as an indicator for policy support: a
           multi-level application

    • Abstract: One Ecosystem 7: e72685
      DOI : 10.3897/oneeco.7.e72685
      Authors : Grazia Zulian, Federica Marando, Lorenzo Mentaschi, Claudia Alzetta, Bettina Wilk, Joachim Maes : Green spaces are increasingly recognised as key elements in enhancing urban resilience as they provide several ecosystem services. Therefore, their implementation and monitoring in cities are crucial to meet sustainability targets.In this paper, we provide a methodology to compute an indicator that assesses changes in vegetation cover within Urban Green Infrastructure (UGI). Such an indicator is adopted as one of the indicators for reporting on the key area “nature and biodiversity” in the Green City Accord (GCA).In the first section, the key steps to derive the indicator are described and a script, which computes the trends in vegetation cover using Google Earth Engine (GEE), is provided.The second section describes the application of the indicator in a multi-scale, policy-orientated perspective. The analysis has been carried out in 696 European Functional Urban Areas (FUAs), considering changes in vegetation cover inside UGI between 1996 and 2018. Results were analysed for the EU and the United Kingdom. The Municipality of Padua (Italy) is used as a case study to illustrate the results at the local level.Over the last 22 years, a slight upward trend characterised the vegetation growth within UGI in European FUAs. Within core cities and densily built-upcommuting zones, the trend was stable; in non-densely built-up areas, an upward trend was recorded. Vegetation cover in UGI has been relatively stable in European cities. However, a negative balance between abrupt changes in greening and browning has been recorded, affecting most parts of European cities (75% of core cities and 77% of commuting zones in densely built-up areas). This still indicates ongoing land take with no compensation of green spaces that are lost to artificial areas.Focusing on the FUA of Padua, a downward trend was observed in 33.3% and 12.9% of UGI in densely built-up and not-densely built-up areas, respectively. Within the FUA of Padua, most municipalities are characterised by a negative balance between abrupt greening and browning, both in non-densely built-up and densely built-up areas.This approach complements traditional metrics, such as the extent of UGI or tree canopy cover, by providing a valuable measure of condition of urban ecosystems and an instrument to monitor the impact of land take.

  • U-shaped deep-learning models for island ecosystem type classification, a
           case study in Con Dao Island of Vietnam

    • Abstract: One Ecosystem 7: e79160
      DOI : 10.3897/oneeco.7.e79160
      Authors : Kinh Bac Dang, Thi Ha Thanh Nguyen, Huu Duy Nguyen, Quang Hai Truong, Thi Phuong Vu, Hanh Nguyen Pham, Thi Thuy Duong, Van Trong Giang, Duc Minh Nguyen, Thu Huong Bui, Benjamin Burkhard : The monitoring of ecosystem dynamics utilises time and resources from scientists and land-use managers, especially in wetland ecosystems in islands that have been affected significantly by both the current state of oceans and human-made activities. Deep-learning models for natural and anthropogenic ecosystem type classification, based on remote sensing data, have become a tool to potentially replace manual image interpretation. This study proposes a U-Net model to develop a deep learning model for classifying 10 island ecosystems with cloud- and shadow-based data using Sentinel-2, ALOS and NOAA remote sensing data. We tested and compared different optimiser methods with two benchmark methods, including support vector machines and random forests. In total, 48 U-Net models were trained and compared. The U-Net model with the Adadelta optimiser and 64 filters showed the best result, because it could classify all island ecosystems with 93 percent accuracy and a loss function value of 0.17. The model was used to classify and successfully manage ecosystems on a particular island in Vietnam. Compared to island ecosystems, it is not easy to detect coral reefs due to seasonal ocean currents. However, the trained deep-learning models proved to have high performances compared to the two traditional methods. The best U-Net model, which needs about two minutes to create a new classification, could become a suitable tool for island research and management in the future. HTML XML PDF

  • General guidance for custom-built structural equation models

    • Abstract: One Ecosystem 7: e72780
      DOI : 10.3897/oneeco.7.e72780
      Authors : James Grace : Structural Equation Modelling (SEM) represents a quantitative methodology for specifying and evaluating causal network hypotheses. The application of SEM typically involves the use of specialised software packages that implement estimation procedures and automate model checking and the output of summary results. There are times when the specification details an investigator wishes to implement to represent their data relationships are not supported by available SEM packages. In such cases, it may be desirable to develop and evaluate SE models “by hand”, using specialised regression tools. In this paper, I demonstrate a general approach to custom-built applications of SEM. The approach illustrated can be used for a wide array of specialised applications of non-linear, multi-level and other custom specifications in SE models. HTML XML PDF

  • Assessing ecosystem services of abandoned agricultural lands: a case study
           in the forested zone of European Russia

    • Abstract: One Ecosystem 7: e77969
      DOI : 10.3897/oneeco.7.e77969
      Authors : Daria Anpilogova, Alla Pakina : The massive abandonment of arable land in Russia in the 1990s had a heavy impact on the country’s land-use structure. The cessation of cultivation leads to a decrease of provisioning ecosystem services within the landscape, while creating an opportunity to enhance the supply of diverse regulation services. Consideration of this opportunity is increasingly important for environmental management and landscape planning. In this article, we present an approach for assessing the environmental benefits of ecosystems developing on abandoned arable lands in the forested zone of European Russia. The proposed methodology is established on a land-cover based framework – ecosystem services assessment matrix. For assessment purposes, abandoned arable lands at different stages of vegetation recovery succession (ruderal, grassland and small-leaved forest) are considered as different land-cover types. Four classes of regulating ecosystem services are subject to qualitative analysis: regulation of the chemical composition of the atmosphere, control of erosion rates, regulation of soil quality and pollination. An exemplary application of the proposed methodology for the case study area located in the Moscow Region of Russia is presented in the article. The results of the qualitative assessment revealed an association between the stage of vegetation recovery succession which corresponds with the time since land abandonment and the supply of regulating ecosystem services. The recovery of natural vegetation leads to higher levels of carbon sequestration, more effective erosion mitigation, soil recovery and increased pollinator abundance. Cropland was proven to be a recipient of the services provided by natural ecosystems. Thus, the return of all uncultivated fields to agricultural use will cause a substantial decrease in the ecological value of the study area. HTML XML PDF

  • Mapping and assessment of ecosystem services at Troodos National Forest
           Park in Cyprus

    • Abstract: One Ecosystem 7: e77584
      DOI : 10.3897/oneeco.7.e77584
      Authors : Constantinos Kounnamas, Marios Andreou : Troodos National Forest Park is located in the centre of Troodos mountain range and it is one of the most important natural environments of Cyprus. It has been included to the Natura 2000 network of the Island due to its important natural ecosystems and its great biodiversity. Based on the Common International Classification of Ecosystem Services (CICES 5.1), 36 ecosystem services have been identified in the area. The majority of ecosystem services are concentrated at the Troodos peak and the nearby areas. The same pattern applies for the Cultural Services. Provisioning and Regulation-Maintenance services are concentrated at the centre and western part of the site. The site’s habitat types were mapped and their distribution in the area is presented in respective maps. Carbon stored in plants was 622,705 tonnes in total (73.18 t C per ha), calculated as per habitat type (according to Directive 92/43/EEC - Habitats Directive) and as per TESSA habitat classification. Seven TESSA and 10 Annex I habitat types were identified. The largest part of the site is dominated by Evergreen Broadleaf Forests (7799 ha), followed by Mixed Forests (624 ha) and Deciduous Broadleaf Forests (60 ha). The carbon stock included in AGB (Above Ground Biomass), BGB (Below Ground Biomass), Dead Wood & Litter and SOM (Soil Organic Matter) was evaluated for each habitat type. The annual carbon biomass removal (roundwood and fuelwood) is 80.82 t C y-1 (0.009 t C y-1 per ha), while the carbon sequestered in Troodos National Forest Park is 11,880.33 t CO2 eq y-1 (0.38 t C y-1 per ha). The information produced serves as a useful tool to competent authorities for raising awareness on the importance of ecosystem services and increase the public’s support in the area’s conservation.

  • Cryoconites as biogeochemical markers of anthropogenic impact in high
           

    • Abstract: One Ecosystem 7: e78028
      DOI : 10.3897/oneeco.7.e78028
      Authors : Evgeny Abakumov, Ivan Kushnov, Timur Nizamutdinov, Rustam Tembotov : The globalisation and omnidirectional character of anthropogenic processes has challenged scientists around the world to estimate the harmful effects of these processes on ecosystems and human health. Polycyclic aromatic hydrocarbons (PAHs) is one the most infamous group of contaminants, originated both from natural and anthropogenic processes. They could transport to high latitudes and altitudes through atmospheric long-distance transfer and further enter ecosystems of these vulnerable regions by deposition on terrestrial surfaces. An interesting object for tracking transboundary contamination processes in high mountain ecosystems is called cryoconite. Cryoconite, a dark-coloured supraglacial sediment which is abundant in polar and mountain environments, is considered as a storage of various pollutants, including PAHs. Thus, it may pose a risk for local human health and ecosystem through short-distance transfer. Studied cryoconite sediments were collected at the surface of Skhelda and Garabashi glaciers, Central Caucasus high-mountain region, as well as mudflow, moraine material and local soils at the Baksan Gorge in order to examine levels of their contamination. We analysed the content of 15 priority polyaromatic compounds from the US EPA list and used the method of calculation of PAHs isomer ratios with the purpose of identifying their source. To estimate their potential toxicity, Benzo[a]pyrene (BaP) equivalents were calculated. Maximum concentration was defined for NAP (84 ng×g-1), PHE (40 ng×g-1) and PYR (47 ng×g-1), with the minimum concentration for ANT (about 1 ng×g-1). The most polluted material is a cryoconite from Garabashi glacier because of local anthropogenic activities and long-distance transfer. High-molecular weight PAHs are dominated in PAHs composition of almost all samples. The most common sources of PAHs in studied materials are combustion processes and mixed pyrolytic/petrogenic origin. Toxicity levels of separate PAHs did not exceed the maximum permissible threshold concentrations values in most cases. However, the sum of PAHs in BaP equivalents exceed the threshold values in all samples, in some of them more than twice. HTML XML PDF
