Assessing ecological status with diatoms DNA metabarcoding: Scaling-up on a WFD monitoring network (Mayotte island, France)
01. November 2017
Publication date: November 2017 Source:Ecological Indicators, Volume 82 Author(s): Valentin Vasselon, Frédéric Rimet, Kálmán Tapolczai, Agnès Bouchez Diatoms are excellent ecological indicators of water quality because they are broadly distributed, they show high species diversity and they respond rapidly to human pressures. In Europe, the Water Framework Directive (WFD) gives the legal basis for the use of this indicator for water quality assessment and its management. Several quality indices, like the Specific Polluosensitivity Index (SPI), were developed to assess the...
An intelligent system for estimating frog community calling activity and species richness
01. November 2017
Publication date: November 2017 Source:Ecological Indicators, Volume 82 Author(s): Jie Xie, Michael Towsey, Mingying Zhu, Jinglan Zhang, Paul Roe Over the past decade, dramatic declines in frog populations have been noticed worldwide. To examine this decline, monitoring frogs is becoming increasingly important. Compared to traditional field survey methods, recent advances in acoustic sensor technology have greatly extended spatial and temporal scales for monitoring animal populations. In this paper, we examine the problem of monitoring frog populations by analysing acoustic...
Optimizing coastal and marine spatial planning through the use of high-resolution benthic sensitivity models
01. November 2017
Publication date: November 2017 Source:Ecological Indicators, Volume 82 Author(s): Daniel Gorman, Guilherme Corte, Helio Herminio Checon, A. Cecilia Z. Amaral, Alexander Turra Effective management of coastal and marine resources requires knowledge of how community sensitivity varies spatially. With this in mind, we developed a benthic sensitivity index (SI), based on the distribution and abundance of five ecological groups that can be used to assess community tolerance to organic enrichment and other disturbances. The index, projected as a high-resolution map, ranks...

01. November 2017
Publication date: November 2017 Source:Ecological Indicators, Volume 82 Author(s): Zhonghua Cheng, Lianshui Li, Jun Liu Exploring exactly where air pollution comes from, and identifying the key factors that influence it, can provide a scientific basis for the rational formulation and effective implementation of air pollution policies in China. Based on the data from 2001 to 2012 covering PM2.5 concentrations in 285 Chinese cities, we use dynamic spatial panel models to empirically analyze the key driving factors of this air pollution. Results show that China’s urban smog...
Predicting gastrointestinal infection morbidity based on environmental pollutants: Deep learning versus traditional models
01. November 2017
Publication date: November 2017 Source:Ecological Indicators, Volume 82 Author(s): Qin Song, Mei-Rong Zhao, Xiao-Han Zhou, Yu Xue, Yu-Jun Zheng Accurate morbidity prediction can contribute greatly to the efficiency of medical services. Gastrointestinal infectious diseases are largely influenced by environmental pollutants, but predicting their morbidity based on pollution indicators is quite difficult because of the complex relationship between the pollutants and the infections. This study presents a deep neural network (DNN) model for estimating the morbidity of...
Nonlinearity, fuzziness and incommensurability in indicator-based assessments of vulnerability to climate change: A new mathematical framework
01. November 2017
Publication date: November 2017 Source:Ecological Indicators, Volume 82 Author(s): Abbas El-Zein, Fahim N Tonmoy The earth’s climate system is highly nonlinear and the vulnerability of a community to a climate hazard is no exception. While this fact is widely accepted, indicator-based vulnerability assessments (IBVA) hardly ever take such nonlinearities into account. This is mainly due to the fact that the majority of assessment studies use methods based on Multiple Attribute Utility Theory (MAUT) (e.g. simple additive weight or multiplicative aggregation) to aggregate indicators...
Nation-wide indicators of ecological integrity in Mexico: The status of mammalian apex-predators and their habitat
01. November 2017
Publication date: November 2017 Source:Ecological Indicators, Volume 82 Author(s): Franz Mora Ecological indicators that evaluate the status and trends of mammalian apex predators are necessary for monitoring the ecological integrity of landscapes. Several nation-wide spatial indicators that describe the status of apex predators after habitat transformation have been developed for México. These spatial indicators show the condition of the remnant natural landscape for maintaining the complexity of predator-prey interactions and habitat selection and use. The indicators were obtained...

From phylogenetic to functional originality: Guide through indices and new developments
01. November 2017
Publication date: November 2017 Source:Ecological Indicators, Volume 82 Author(s): Sandrine Pavoine, Michael B. Bonsall, Amaël Dupaix, Ute Jacob, Carlo Ricotta In biodiversity studies a species is often classified as original when it has few closely related species, a definition that reflects its phylogenetic originality. More recently, studies have focussed on biological or functional traits that reflect the role(s) that species play within communities and ecosystems. This has led many studies to an alternative evaluation of species’ originality: its functional...
