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...
sc_PDSI is more sensitive to precipitation than to reference evapotranspiration in China during the time period 1951–2015
###RSS_DATE###
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...
