01. Oktober 2018
Publication date: October 2018 Source:Ecological Indicators, Volume 93 Author(s): Chao Xu, Dagmar Haase, Stephan Pauleit Green spaces can mitigate the negative impacts of urbanization and improve the overall quality of life of urban residents, but the availability of green spaces has been extensively influenced by urban dynamics. In this study, multiple scenarios were developed for one of the fastest and most dynamically growing urban regions in Germany, Munich, with respect to the following three dimensions: housing demand (high, medium or low), urban spatial structure...
Direct toxicity of the water-soluble fractions of a crude and a diesel-motor oil on the survival of free-living nematodes
01. Oktober 2018
Publication date: October 2018 Source:Ecological Indicators, Volume 93 Author(s): Luana Monteiro, Walter Traunspurger, Kevin Roeleveld, Frederic Lynen, Tom Moens The water-soluble fraction (WSF) of an oil contains different classes of petroleum hydrocarbons and, despite their low potential for bioaccumulation, these can be highly toxic to biota. Nematodes are usually the most abundant and species-rich group of metazoans in marine and freshwater sediments as well as terrestrial soils and have been proposed as excellent models to monitor pollution effects. The first aim of this...

Two contrasting seasonal patterns in microbial nitrogen immobilization from temperate ecosystems
01. Oktober 2018
Publication date: October 2018 Source:Ecological Indicators, Volume 93 Author(s): Xinyue Zhang, Hui Zeng, Wei Wang Ecosystems with seasonal snow cover and soil frost comprise more than half of the terrestrial ecosystems. Recent studies have reported peak microbial biomass carbon (MBC) and nitrogen (MBN) in late winter in alpine and arctic regions, followed by a rapid decline when soil temperatures rise to 0 °C. In these snow-covered ecosystems, the N incorporated into microbes from soil during winter is considered vital for plant nutrient uptake in the following growing...

Publication date: October 2018 Source:Ecological Indicators, Volume 93 Author(s): Mohammed Alamgir, Stephen M. Turton, Mason J. Campbell, Colin J. Macgregor, Petina L. Pert Tropical forests are the storehouse of both ecosystem services and biodiversity but the interlinkages between these two components of ecosystems are yet to be fully explored. We utilized expert opinion to assess the key and multiple ecosystem services, and biodiversity in a tropical landscape. We found that key and multiple ecosystem services supply varies across the landscape and that forest disturbances...

01. Oktober 2018
Publication date: October 2018 Source:Ecological Indicators, Volume 93 Author(s): Min Huang, Shuanglü Shan, Fangbo Cao, Jiana Chen, Yingbin Zou Environmental costs from nitrogen (N) loss have been substantial in Chinese rice cropping systems. Naturally occurring fallow weeds may provide a similar ecosystem service as cover crops in scavenging N with the advantage of no inputs. In this study, an on-farm experiment and 15N-tracing micro-plot experiment were conducted to: (1) investigate the aboveground biomass and N uptake by fallow weeds; and (2) quantify the sources of N...
Modeling spatial and temporal dynamics of plant species richness across tidal creeks in a temperate salt marsh
01. Oktober 2018
Publication date: October 2018 Source:Ecological Indicators, Volume 93 Author(s): Daehyun Kim In salt marsh ecology, various indicators, including environmental, biological, and anthropogenic factors, have been used to predict the patterns of plant species richness. The potential impact of spatial autocorrelation on this prediction, however, has yet to receive much attention. In this paper, two sets of regression models were developed to predict spatial patterns (in 2006) and temporal changes (from 2006 to 2012) of richness across selected tidal creeks at a Danish salt marsh: (1...
Indicator value of trees for soil reaction in cool-humid forests
01. Oktober 2018
Publication date: October 2018 Source:Ecological Indicators, Volume 93 Author(s): O.T. Bouman Acid rain, soil mineral weathering, and the interception of dust and sea salt still obscure the evaluation of tree effects on soil reaction in mature natural forests. The null hypothesis that tree species and size do not differentiate soil pH was tested in four ways: (i) comparison of an evergreen conifer ecosystem with a history of elevated exposure to acidifying emissions vs. a deciduous angiosperm ecosystem in a rural area; (ii) soil trenching to exclude mineral nutrient and water uptake...
