A sensitivity analysis to methodological variation in indicator-based urban sustainability assessment: a Quebec case study
01. Dezember 2017
Publication date: December 2017 Source:Ecological Indicators, Volume 83 Author(s): Juste Rajaonson, Georges A. Tanguay Methodological factors are often acknowledged for their impact on the urban sustainability assessment outcomes. The significance of this impact, however, divides those who assign it great importance; to the point of compromising any attempt at sustainability benchmarking using indicators, from those who regard it as having a relatively limited role. In this paper, we aim to contribute to this debate by assessing how methodological choices could influence the...

Functional identity of overstorey tree height and understorey conservative traits drive aboveground biomass in a subtropical forest
01. Dezember 2017
Publication date: December 2017 Source:Ecological Indicators, Volume 83 Author(s): Arshad Ali, En-Rong Yan The niche complementarity hypothesis has received empirical support but species differ in functional strategies for their contribution to ecosystem function, as predicted by the mass ratio hypothesis. Our understanding of how functional identity of conservative and acquisitive strategies of trees predicts aboveground biomass across forest strata (i.e. overstorey and understorey) remains unclear. Aboveground biomass, community-weighted mean (CWM − functional identity) of...
