Analyzing spatio-temporal changes and trade-offs to support the supply of multiple ecosystem services in Beijing, China
###RSS_DATE###
Publication date: November 2018Source: Ecological Indicators, Volume 94, Part 1Author(s): Xiao Sun, Zhongming Lu, Feng Li, John C. CrittendenAbstractRapid urbanization has dramatically changed regional land use patterns and brought enormous pressures on ecosystem services (ESs). The assessment of the impact of urbanization on ESs is critical for sustainable urban planning and land policy in China. In this study, we used the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model to assess the changes in ESs based on land use patterns in Beijing from 1984 to 2015. A new...
High degree of philopatry is required for mobile insects used as local indicators in biodiversity studies
###RSS_DATE###
Publication date: November 2018Source: Ecological Indicators, Volume 94, Part 1Author(s): Anna Talašová, Jakub Straka, Jiří Hadrava, Daniel Benda, František Kocourek, Jan KazdaAbstractLocal changes in land use and climatic conditions provoke transformations of habitats and therefore, distribution changes of species in the landscape. Different insect groups are repeatedly used as indicators of local ecological conditions in biodiversity research. Here we suggest that only highly philopatric groups can be relevant indicators pointing to differences in ecological conditions among...

Suitability of NDVI and OSAVI as estimators of green biomass and coverage in a semi-arid rangeland
###RSS_DATE###
Publication date: November 2018Source: Ecological Indicators, Volume 94, Part 1Author(s): Rachel R. Fern, Elliott A. Foxley, Andrea Bruno, Michael L. MorrisonAbstractRangelands are often too large and inaccessible to determine biomass accumulation and vegetation cover by ground surveys alone, particularly in semi-arid regions where productivity per unit area is typically low and highly variable. Thus, the development of remote sensing derived spectral indices have been of particular interest to rangeland managers as a more cost-effective means of measuring the characteristics, biomass, and...

###RSS_DATE###
Publication date: November 2018Source: Ecological Indicators, Volume 94, Part 1Author(s): Dario Torregrossa, Antonino Marvuglia, Ulrich LeopoldAbstractThe high-frequency on-line measurements coming from sensors installed in wastewater treatment plants (WWTPs) can be used for alert systems and decision support tools. Given the complexity of WWTPs, many authors developed efficient techniques for plant assessment. By contrast, few contributions are focussed on the identification of regime shifts in WWTPs on short-term, even if the early detection of occurring inefficiencies is a relevant...
Effects of long-term nitrogen and phosphorus addition on plant defence compounds in a freshwater wetland
###RSS_DATE###
Publication date: November 2018Source: Ecological Indicators, Volume 94, Part 1Author(s): Liping Shan, Changchun Song, Xinhou Zhang, Jiusheng RenAbstractProminent theories of plant defence have predicted that alleviating nutrient limitation will result in decreased production of defence compounds. Yet effects of nutrient addition on plant defence compounds have been found to vary, and research on plant resource allocation in different organs in response to long-term nutrient addition is limited. In this study, we aimed to elucidate effects of 12-yr nitrogen (N) addition and 10-yr...
Threatened grassland butterflies as indicators of microclimatic niches along an elevational gradient – Implications for conservation in times of climate change
###RSS_DATE###
Publication date: November 2018Source: Ecological Indicators, Volume 94, Part 1Author(s): Gregor Stuhldreher, Thomas FartmannAbstractAmong the factors that determine habitat quality for butterflies, an adequate microclimate is of crucial importance, especially for the less mobile immature stages. Due to their narrow microclimatic preferences, stenotopic butterflies are potential indicators of specific microclimatic niches. Although the outstanding importance of the microclimate is widely acknowledged, the thermal and hygric requirements of butterflies are usually inferred from habitat...

###RSS_DATE###
Publication date: October 2018Source: Ecological Indicators, Volume 93Author(s): Holly L. Bernardo, Pati Vitt, Rachel Goad, Susanne Masi, Tiffany M. KnightAbstractEnsuring the best use of limited conservation resources requires comprehensively assessing the relative importance of multiple threats, some of which occur at local and some at regional spatial scales. Multiple threats are rarely modeled in traditional population viability analyses (PVAs) due to the high data requirements necessary to parameterize age or stage based population models. Count based PVAs have been shown to provide...

###RSS_DATE###
Publication date: October 2018Source: Ecological Indicators, Volume 93Author(s): Gang Shao, Basil V. Iannone, Songlin FeiAbstractAccurate estimation of forest interior is essential for large scale sustainable forest management. Conventional 2D forest cover maps only indicate the presence and absence of forests and may introduce quantity and allocation bias in the delineation of forest interior due to the inclusion of early successional/recently disturbed forests. We addressed this issue by utilizing both lidar data and National Land Cover Database (NLCD) to generate a 3D forest cover map...
