Here, we explore the concordance between present-day Cladocera...
The need for standardisation: Exemplified by a description of the diversity, community structure and ecological indices of soil nematodes
01. April 2018
Publication date: April 2018 Source:Ecological Indicators, Volume 87 Author(s): B.S. Griffiths, G.A. de Groot, I. Laros, D. Stone, S. Geisen Molecular approaches are offering a supplement to, or even the possibility of replacing morphological identification of soil fauna, because of advantages for throughput, coverage and objectivity. We determined ecological indices of nematode community data from four sets of duplicate soil cores, based on morphological identification of nematodes after elutriation from 200 g soil and high throughput sequencing (HTS) targeting nematodes...
Land use policy as an instrument of rural resilience – The case of land withdrawal mechanism for rural homesteads in China
01. April 2018
Publication date: April 2018 Source:Ecological Indicators, Volume 87 Author(s): Xianjin Huang, Huan Li, Xiaoling Zhang, Xin Zhang Resilience has emerged as an attractive conceptual approach for theorizing rural development in terms of highly complex, vulnerable and adaptive systems. In China, land use policies have evidently influenced rural resilience. We conduct a co-citation analysis, especially the visualization of co-citation networks and research clusters, using CiteSpace 4.0.R5. Based on the analysis and literature review, we develop an assessment index system comprising...

In this study, seven drought indices were employed to develop an aggregate drought index (ADI) to quantify the drought effect on crop yield in the North China Plain (NCP). Based on time-series and panel regression models, relationships between climatic yield anomalies of...
Infrared spectroscopy as a tool for the assessment of soil biological quality in agricultural soils under contrasting management practices
01. April 2018
Publication date: April 2018 Source:Ecological Indicators, Volume 87 Author(s): F. Comino, V. Aranda, R. García-Ruiz, M.J. Ayora-Cañada, A. Domínguez-Vidal Soil quality estimation is one of the most important means of evaluating changes in soil resulting from management. However, there is still no unanimity about what parameters should be included in soil quality assessment. Although there is a consensus on the inclusion of biological variables, mainly because they are robust and tend to show a short-term response after disturbances, their measurement is usually expensive...

Assessing the long-term causal effect of trout invasion on a native charr
01. April 2018
Publication date: April 2018 Source:Ecological Indicators, Volume 87 Author(s): Kentaro Morita Many studies have indicated that invasive species can drive declines in native species through interspecific competition. In freshwater ecosystems, brown trout (Salmo trutta) and rainbow trout (Oncorhynchus mykiss) have been implicated in reducing native species, especially congeneric salmonid fishes. However, demonstrating causality in the wild is problematic because non-natives might replace natives in areas where the former were extirpated by other environmental changes. Using the...
