Choices of abundance currency, community definition and diversity metric control the predictive power of macroecological models of biodiversity

چکیده
Aim This study focuses on the influence of methodological choices on the predictive performance of macroecological models (MEMs), i.e. statistical models designed to predict patterns of biodiversity using environmental predictors. We emphasize the influence of three methodological choices: (1) the choice of the currency in which the abundance of each species is measured, i.e. numbers of individuals or biomass; (2) the rules used to define the species assemblage under focus, i.e. broad communities or refined ecological guilds; and (3) the influence of rare over common species in the biodiversity measure.

متن کاملDefinition of General Operator Space and The s-gap Metric for Measuring Robust Stability of Control Systems with Nonlinear Dynamics
In the recent decades, metrics have been introduced as mathematical tools to determine the robust stability of the closed loop control systems. However, the metrics drawback is their limited applications in the closed loop control systems with nonlinear dynamics. As a solution in the literature, applying the metric theories to the linearized models is suggested. In this paper, we show that usin...
متن کاملMacroecological scale effects of biodiversity on ecosystem functions under environmental change
Conserving different spatial and temporal dimensions of biological diversity is considered necessary for maintaining ecosystem functions under predicted global change scenarios. Recent work has shifted the focus from spatially local (α-diversity) to macroecological scales (β- and γ-diversity), emphasizing links between macroecological biodiversity and ecosystem functions (MB-EF relationships). ...
متن کاملEffects of environmental factors on species diversity of rotifers using biodiversity indicators and canonical correlation analysis (CCA)
Rotifers are microscopic aquatic animals of phylum Rotifera, live in a diverse range of aquatic habitats. They are important in ecology of freshwater ecosystems by recycling nutrients and can alter trophic dynamic of planktonic communities. These features have also been used to infer environmental conditions in an aquatic habitat. Because of the important roles of this group of animals in the t...

Golbolagh Reservoir is located the east of Kurdistan province with 8.1 Million cubic meters' capacity. This study was conducted for one year to investigate the population structure, diversity and seasonal change of phytoplankton of Golbolagh Lake. Some physicochemical parameters of this water body at each sampling site were studied. In this study, 6 phylum, 22 families and 23 genus of phytoplan...
