Miranda, Fabiane Gallucci, Francisco BarrosAbstractThe potential effects of perturbations by Polycyclic Aromatic Hydrocarbons (PAHs) on nematode and macrobenthos assemblages were investigated using the Biological Traits Analysis (BTA). We sampled at tidal flats near an oil refinery and in a reference estuary. Morphological and ecological traits of benthic fauna were selected and analyzed in order to assess the contribution of PAHs concentrations, the... | ||
| Phylogenetic clustering in beneficial attributes of tree species directly linked to provisioning, regulating and cultural ecosystem services | ||
| ###RSS_DATE### | ||
| Publication date: January 2019Source: Ecological Indicators, Volume 96, Part 1Author(s): Chihiro Oka, Masahiro Aiba, Tohru NakashizukaAbstractPhylogenetic diversity is expected to be an important predictor of ecosystem multifunctionality because distant relatives are often more functionally different than close relatives. However, the general extent of non-random linkages between phylogeny and ecosystem services remains unclear. In this study, we examined phylogenetic clustering and associations of beneficial attributes of tree species that are essential for various aspects of ecosystem... | ||

| Publication date: January 2019Source: Ecological Indicators, Volume 96, Part 1Author(s): Yajie Zhang, Gaopeng Li, Jing Ge, Yao Li, Zhisheng Yu, Haishan NiuAbstractThe self-calibrating Palmer Drought Severity Index (sc_PDSI) is developed within the frame of the PDSI model, but is considered to be more appropriate for global drought monitoring. The sc_PDSI can automatically calibrate itself at any location using dynamically computed values and can calculate evapotranspiration using the FAO-56 Penman–Monteith (P–M) equation. However, the correlation of the sc_PDSI(P–M) with some factors... | ||
| Reproductive performance of Octopus maya males conditioned by thermal stress | ||

| ###RSS_DATE### | ||
| Publication date: January 2019Source: Ecological Indicators, Volume 96, Part 1Author(s): Mansi Tripathi, Sunil Kumar SingalAbstractWater Quality Index (WQI) is one of the most widely used concepts for representation of the quality of a water resource. This concept has wide acceptance among policy makers and other stakeholders as this gives a clear and comprehensive picture of the status of the pollution of a water body. The standard step of development of a WQI are – parameter selection, assignment of weights, development of sub-index functions and final aggregation of weighted sub... | ||
| Tree-ring-based drought variability in the eastern region of the Silk Road and its linkages to the Pacific Ocean | ||
| ###RSS_DATE### | ||
| Publication date: January 2019Source: Ecological Indicators, Volume 96, Part 1Author(s): Changfeng Sun, Yu LiuAbstractDrought variability from 1568 to 2014 was presented for the eastern region of the Silk Road by using five tree-ring chronologies and an optimal information extraction method (i.e., one of the composite-plus-scale methods). The inspection results of the split calibration-verification procedure for the transfer functions showed that the reconstructed Palmer drought severity index (PDSI) was credible throughout the entire time interval. During the past 447 years, there were... | ||
| Long-term ecological footprints of a man-made freshwater discharge onto a sandy beach ecosystem | ||
| ###RSS_DATE### | ||
| Publication date: January 2019Source: Ecological Indicators, Volume 96, Part 1Author(s): Gabriela Jorge-Romero, Diego Lercari, Leonardo Ortega, Omar DefeoAbstractSandy shores comprise one of the coastal ecosystems most vulnerable to human impacts, and they are increasingly affected by a variety of stressors. Local-scale drivers such as man-made freshwater discharges have changed the salinity, temperature and nutrient regimes, leading to the degradation of sandy beaches. However, there is still little understanding about the effects of salinity changes on the structure and functioning of... | ||

| Publication date: January 2019Source: Ecological Indicators, Volume 96, Part 1Author(s): Iain A. Malcolm, Karen J. Millidine, Ross S. Glover, Faye L. Jackson, Colin P. Millar, Robert J. FryerAbstractElectrofishing data are commonly collected to assess the status of salmonid populations. However, their interpretation can be challenging without a benchmark measure of abundance against which they can be compared, leading some practitioners to question the value of these data. Juvenile density models that relate salmonid abundance to habitat characteristics offer one approach for developing... | ||
| Temporal changes in accumulation of trace metals in vegetative and generative parts of Xanthoria parietina lichen thalli and their implications for biomonitoring studies | ||
| ###RSS_DATE### | ||
| Publication date: January 2019Source: Ecological Indicators, Volume 96, Part 1Author(s): Kaja Rola, Piotr OsyczkaAbstractCertain lichens are widely used in air pollution biomonitoring because the contents of various elements in their thalli accurately reflect the chemical composition of the air. Temporal changes in selected concentrations of trace metals in vegetative and generative parts of Xanthoria parietina thalli exposed to urban-related pollution were analysed and the relationship between anatomical organisation and element accumulation identified. The lichen material included thalli... | ||
