Associations among taxonomic diversity, functional diversity and evolutionary distinctiveness vary among environments
01. Mai 2018
Publication date: May 2018 Source:Ecological Indicators, Volume 88 Author(s): Federico Morelli, Yanina Benedetti, Paolo Perna, Riccardo Santolini Diversity metrics are commonly used to measure or quantify species-level biodiversity in a given area. In recent decades, ecologists developed many measures and indices in order to quantify a larger proportion of information about communities or species assemblages. Commonly these measures are based on species richness or species evenness, in relation to their relative abundance. Among the most common diversity metrics are the indices...
Examination of effects of acid and metals on benthic algae in streams using chemical diffusing substrata
01. Mai 2018
Publication date: May 2018 Source:Ecological Indicators, Volume 88 Author(s): Dean M. DeNicola, Michael G. Stapleton, Aaron J. Onufrak Acid mine drainage environments have multiple stressors, making it difficult to isolate effects of individual contaminants on benthic algal communities in situ in order to develop more specific indicators. Additionally, responses to AMD contaminants may be dependent on the abiotic and biotic conditions within the affected stream. We examined the efficacy of using chemical diffusing substrata (CDS) to determine how acid and metals interact to...
δ13C, δ15N, N concentration, C/N, and Ca/Al of Pinus densiflora foliage in Korean cities of different precipitation pH and atmospheric NO2 and SO2 levels
01. Mai 2018
Publication date: May 2018 Source:Ecological Indicators, Volume 88 Author(s): Hye In Yang, Hyun-Jin Park, Kwang-Seung Lee, Sang-Sun Lim, Jin-Hyeob Kwak, Seung-Il Lee, Scott X. Chang, Sang-Mo Lee, Woo-Jung Choi Forest decline due to atmospheric pollution is a consequence of long-term chronic exposure, and thus chemical proxies that are sensitive to the pollution are helpful in estimating the impact of atmospheric pollution on forest health. In this study, we explored changes in the isotopic and elemental compositions of needles of red pine (Pinus densiflora) with...

01. Mai 2018
Publication date: May 2018 Source:Ecological Indicators, Volume 88 Author(s): Meenu Gautam, Bhanu Pandey, Madhoolika Agrawal Plant community structure studies on derelict sites are providing significant insights into vegetation dynamics to ensure the success of future revegetation projects in such areas. Therefore, the present study was conducted to evaluate the changes in soil physico-chemical and biological properties at abandoned red mud dumps (RMD) compared to residential (RS) and forest (FS) sites, coupled with their consequent impacts on the plant community structure. An...
Transition from abstract thermodynamic concepts to perceivable ecological indicators
01. Mai 2018
Publication date: May 2018 Source:Ecological Indicators, Volume 88 Author(s): Hua Lin, Houlei Zhang, Qinghai Song Entropy and exergy are the central concepts in thermodynamics, and many researchers have used them to characterize ecosystem development. However, these concepts are very abstract to outsiders. Direct measurements of the indicators related to entropy and exergy are difficult and involve large errors. Schneider and Kay (1994) bridged thermodynamic concepts, i.e., entropy and exergy, with perceivable ecological indicators, i.e., canopy surface temperature (T surf) and...
Flow alterations by dams shaped fish assemblage dynamics in the complex Mekong-3S river system
01. Mai 2018
Publication date: May 2018 Source:Ecological Indicators, Volume 88 Author(s): Peng Bun Ngor, Pierre Legendre, Thierry Oberdorff, Sovan Lek The Mekong, Sekong, Sesan, and Srepok (Mekong-3S) river system, a Ramsar wetlands of international importance and critical fish migration routes, is altered by dams that distort the seasonal flow dynamics, structuring dispersal and reproduction success of fishes. Here, we investigate the temporal responses of local fish beta diversity to hydrologic modification by the upstream functioning dams in five sites of the Mekong-3S system. The...

Age structure as an indicator of poaching pressure: Insights from rapid assessments of elephant populations across space and time
01. Mai 2018
Publication date: May 2018 Source:Ecological Indicators, Volume 88 Author(s): Trevor Jones, Jeremy J. Cusack, Rocío A. Pozo, Josephine Smit, Lameck Mkuburo, Paul Baran, Alex L. Lobora, Simon Mduma, Charles Foley Detecting and monitoring illegal harvesting pressure on wild populations is challenging due to the cryptic nature of poaching activities. Although change in population age structure has been suggested as an indicator of harvesting pressure, few studies have tested its validity when based on short-term field surveys. Using data from rapid demographic...
The utility of point count surveys to predict wildlife interactions with wind energy facilities: An example focused on golden eagles
01. Mai 2018
Publication date: May 2018 Source:Ecological Indicators, Volume 88 Author(s): Maitreyi Sur, James R. Belthoff, Emily R. Bjerre, Brian A. Millsap, Todd Katzner Wind energy development is rapidly expanding in North America, often accompanied by requirements to survey potential facility locations for existing wildlife. Within the USA, golden eagles (Aquila chrysaetos) are among the most high-profile species of birds that are at risk from wind turbines. To minimize golden eagle fatalities in areas proposed for wind development, modified point count surveys are usually conducted...

Publication date: May 2018 Source:Ecological Indicators, Volume 88 Author(s): Marco Martinez, M. Cristina Mangano, Giulia Maricchiolo, Lucrezia Genovese, Antonio Mazzola, Gianluca Sarà Shellfish aquaculture represents a worldwide valuable segment of the aquaculture market, spreading along the Mediterranean coasts, and is sensitive to the still unforeseen, poorly-known effects of climate change. Threats due to temperature rise can threaten the deployment and development of this sector, up until now recognised as the best candidate to mitigate the effects of fishery...
Biological surrogates: A word of caution
01. Mai 2018
Publication date: May 2018 Source:Ecological Indicators, Volume 88 Author(s): Gustavo Filete de Morais, Luiz Guilherme dos Santos Ribas, Jean Carlo Gonçalves Ortega, Jani Heino, Luis Mauricio Bini The value of biological surrogates has been tested for many ecosystems and biological groups. Biological surrogates are biological groups whose biodiversity patterns (e.g. abundance, species richness or assemblage composition) correlate strongly with those of other biological groups. They should thus be cost-effective proxies for overall diversity variation in biodiversity...

01. Mai 2018
Publication date: May 2018 Source:Ecological Indicators, Volume 88 Author(s): Kamrul Islam, Md. Farhadur Rahman, Mohammed Jashimuddin Land use changes generally affect the integrity of an ecosystem. The effect of this change can be very severe if the conversion disrupts a crucial habitat of major plants and animals. The degraded Chunati Wildlife Sanctuary is one such area of Bangladesh which is facing a serious problem of rapid land use change. In this study, the future trend of land use change of the area was modelled using Artificial Neural Network. Several driver variables...
Cryptogamic communities as a useful bioindication tool for estimating the degree of soil pollution with heavy metals
01. Mai 2018
Publication date: May 2018 Source:Ecological Indicators, Volume 88 Author(s): Kaja Rola, Piotr Osyczka Lichens and bryophytes have commonly been used as bioindicators of environmental conditions, especially in relation to air quality. However, their diagnostic role in the assessment of soil pollution is relatively poorly recognised. The aim of this study was to find a pattern of cryptogamic biota structure associated with zinc and lead soil pollution and to thereby identify common signal species useful for bioindication purposes. The study area encompassed various types of...
Relationships between indicators of acid-base chemistry and fish assemblages in streams of the Great Smoky Mountains National Park
01. Mai 2018
Publication date: May 2018 Source:Ecological Indicators, Volume 88 Author(s): Barry P. Baldigo, Matt A. Kulp, John S. Schwartz The acidity of many streams in the Great Smoky Mountains National Park (GRSM) has increased significantly since pre-industrial (∼1850) times due to the effects of highly acidic atmospheric deposition in poorly buffered watersheds. Extensive stream-monitoring programs since 1993 have shown that fish and macroinvertebrate assemblages have been adversely affected in many streams across the GRSM. Matching chemistry and fishery information collected from 389...

MacDonald California’s Mediterranean ecosystem has been identified as one of the Earth’s biodiversity hotspots. The high degree of rapid urbanization along the southern California coastline has resulted in the loss of significant natural areas over the last century and protected areas that do exist may be further threatened by climate change, drought, and fire. We use Moderate Resolution...
Replenishment of landscape water with reclaimed water: Optimization of supply scheme using transparency as an indicator
01. Mai 2018
Publication date: May 2018 Source:Ecological Indicators, Volume 88 Author(s): Dong Ao, Li Luo, Mawuli Dzakpasu, Rong Chen, Tao Xue, Xiaochang C. Wang With shortages of urban water resources, reclaimed water (RW) has become increasingly important as an alternative water source, especially for replenishing landscape waters. To meet the requirements of landscape quality control when RW is used for partial replacement of the surface water (SW) source to a channel-type urban water in a city in northwest China, scenario analyses were carried out by mathematical modelling. Water...
