An integrating approach of cellular automata and ecological network to predict the impact of land use change on connectivity
###RSS_DATE###
Publication date: March 2019Source: Ecological Indicators, Volume 98Author(s): Yun Huang, Tie-Jun LiaoAbstractAs a primary concern in biodiversity conservation, understanding the impact of land use/cover change (LUCC) on functional connectivity has the overarching significance. Yet, LUCC simulation models used in previous studies are insufficient to tackle the complex and non-linear interactions of land-use components, and thus may not be able to provide the accurate impact assessments. This paper aimed to fill this gap and to find a solution that avoids significant connectivity loss in...
Synergistic effects of warming and lower salinity on the asexual reproduction of reef-forming corals
###RSS_DATE###
Publication date: March 2019Source: Ecological Indicators, Volume 98Author(s): Marta Dias, Ana Ferreira, Raúl Gouveia, Catarina VinagreAbstractTropical storms produce competent self-regenerating coral fragments capable of originating new coral colonies. These climatic events are predicted to increase in the future due to ocean warming, the main cause of coral bleaching. Estimated increases in precipitation will affect salinity at shallow reef areas which combined with ocean warming will aggravate the effects of coral bleaching. In this study the long-term effects of increased temperature...
Comparative assessment of two proxies of fish discard survival
###RSS_DATE###
Publication date: March 2019Source: Ecological Indicators, Volume 98Author(s): Marie Morfin, Dorothée Kopp, Hugues P. Benoît, Sonia MéhaultAbstractTwo vitality index approaches have been demonstrated to be good proxies of discard survival in similar fishing and environmental conditions: Reflex Action Mortality Predictors combined with injuries (RI) scores that measure the proportion of impaired reflexes and injuries, and a simpler, quicker, but less precise approach based on ordinal categories related to fish body movements and injuries (semi-quantitative assessment, SQA). This study...
The good and the bad: Identifying homogeneous groups of municipalities in terms of separate waste collection determinants in Italy
###RSS_DATE###
Publication date: March 2019Source: Ecological Indicators, Volume 98Author(s): Massimiliano Agovino, Massimiliano Cerciello, Gaetano MusellaAbstractThe European Commission identifies separate waste collection as a primary factor in its sustainable development strategy. The EU Member States are expected to achieve a separate waste collection rate of 50% by 2020. Although Italy is not very far from such target, it features wide regional variation in the extent of separate collection. Municipal administrations are the key managerial units for the implementation of the environmental policy. By...
Effects of shoreline alteration and habitat heterogeneity on macroinvertebrate community composition across European lakes
###RSS_DATE###
Publication date: March 2019Source: Ecological Indicators, Volume 98Author(s): Gwendolin Porst, Mario Brauns, Kenneth Irvine, Angelo Solimini, Leonard Sandin, Martin Pusch, Oliver MilerAbstractHuman lake shore alterations often result in a substantial decrease of littoral and riparian habitat diversity and physical complexity, but the intensity at which shore alterations affect biodiversity may differ among European geographical regions. We tested if the response of littoral macroinvertebrate communities to human shoreline alterations is consistent among geographical regions. We compared...
Compensatory dynamics on the community structure of fruit-feeding butterflies across hyper-fragmented Atlantic forest habitats
###RSS_DATE###
Publication date: March 2019Source: Ecological Indicators, Volume 98Author(s): Bruno K.C. Filgueiras, Douglas H.A. Melo, Márcio Uehara-Prado, André Victor L. Freitas, Inara R. Leal, Marcelo TabarelliAbstractThe creation of forest edges promotes a drastic extirpation of forest-dependent species across tropical fragmented landscapes. Yet, this loss of forest-dependent species can be compensated by the proliferation of disturbance-adapted species (winner-loser replacement) maintaining community-level attributes in altered habitats. Here, we test whether this replacement reflects a sort of...
Relationships between plant species richness and soil pH at the level of biome and ecoregion in Brazil
###RSS_DATE###
Publication date: March 2019Source: Ecological Indicators, Volume 98Author(s): Natalia Crespo-Mendes, Alexis Laurent, Hans Henrik Bruun, Michael Zwicky HauschildAbstractSoil pH has been used to indicate how changes in soil acidity can influence species loss. The correlation between soil pH and plant species richness has mainly been studied in North America and Europe, while there is a lack of studies exploring Tropical floras. Here, our aim was therefore to investigate the relationships between terrestrial plant species richness and soil pH for the large Brazilian flora, with spatial...
Exploring physical wetland vulnerability of Atreyee river basin in India and Bangladesh using logistic regression and fuzzy logic approaches
###RSS_DATE###
Publication date: March 2019Source: Ecological Indicators, Volume 98Author(s): Tamal Kanti Saha, Swades PalAbstractIn spite of the immense ecological importance of the wetland, wetland habitats are losing their existence in the floodplain regions. In the present study, we have explored the nature of the physical vulnerability of wetland using logistic regression (LR) and fuzzy logic (FL) approaches for both pre and post-dam periods. LR is selected because initial vulnerable is identified and FL is used to explore the best possible alternative interwoven relation among the parameters. Seven...

To determine MT synthesis in wild animals for the purpose of evaluating environmental pollution, the stability of MTs during animal trapping, during the transporting of samples to the laboratory, and during the storing of...
Multi-city comparison of the relationships between spatial pattern and cooling effect of urban green spaces in four major Asian cities
###RSS_DATE###
Publication date: March 2019Source: Ecological Indicators, Volume 98Author(s): Mahyar Masoudi, Puay Yok Tan, Soo Chin LiewAbstractStudies on the role of urban green spaces (UGS) in mitigating the urban heat island (UHI) effect demonstrate the influence of two related, but distinct attributes of UGS: the composition (amount), and configuration (spatial attributes and distribution) of UGS patches. While the positive role of UGS amount in providing cooling effect seems unequivocal, it is still not possible to develop a consensus on the role of UGS configuration from the small number of...

###RSS_DATE###
Publication date: March 2019Source: Ecological Indicators, Volume 98Author(s): Diego Fernandes Gomes Pereira, José Max Barbosa de Oliveira Junior, Leandro JuenAbstractSpecies occurrence can be affected by the availability of environments that fit within the limits of variation of its niche and by interaction with other species. Modifications in the environment, especially those caused by mankind, are considered the leading cause for species extinction. Such a response from the species is not random, with patterns that can follow functionality and/or morphology of each taxa. In this...

Capacity as “virtual stock” in ecosystem services accounting
###RSS_DATE###
Publication date: March 2019Source: Ecological Indicators, Volume 98Author(s): Alessandra La Notte, Sara Vallecillo, Joachim MaesAbstractInterest in ecosystem services accounting is growing exponentially. There are many un-solved issues that need to be addressed, the notion of capacity is among them. International guidelines suggest that capacity should constitute the link between the ecosystem assets accounts and the ecosystem services accounts. In order to address this issue, the authors use Supply and Use table for ecosystem services to show the relationship between (i) ecosystem assets...
