    1. Comprehensive research on the community structure and spatial species diversity of demersal fish assemblages can provide not only species records but also qualitative classifications of species into ecological (functional) or zoogeographical groups for conservation and management purposes

      could be a by-product of my resaerch

    1. Correspondence analysis (CA) is attractive to community ecologists because, in contrast to methods based on principal components analysis, it allows for unimodal responses to underlying gradients, thereby providing a clear representation of ‘long’ gradients (as well as ‘short’ gradients). Detrended correspondence analysis (DCA) corrects for two artefacts in CA: the ‘arch effect’ and compression of the two extremes of the first axis
    1. This study demonstrates the advantages of adopting quantitatively derived clusters of spatially associated species and elucidates the potential of resultant clusters as a spatially explicit framework for investigating distribution-related questions in ecology, biogeography, and conservation.

    1. low operating ratios (i.e., utilization degree of the designed treatment capacity) of the plants (76% in counties and 85% in cities) especially for those in north China, although the situation is plant specific because a considerable fraction of plants (19%) are still running under overload condition.
    1. and therefore those of wastewater. In an urban context, the highest values of COD, TSS, BOD, etc. are usually measured during diurnal hours, with a peak in the morning (more pronounced) and several peaks in the early evening (more distributed)
    2. Toilets produce the most important loads of nitrogen, phosphorus and suspended solids (Gray and Becker, 2002). They represent 60 to 90% of the total flow at the end of the night or early morning and 20–40% during the day.
