Investigating isotopic functional indices to reveal changes in the structure and functioning of benthic communities... This study aims to (i) redefine functional indices originally based on quantitative biological traits of species and demonstrate the ecological significance of newly defined isotopic functional indices (IFI) in a δ-isotopic space, (ii) compare IFI using biomass data with existing unweighted isotopic indices using only isotopic compositions.Using...
Cross-species overlap in isotopic niche pre- and post-bloom.Isotopic niche overlap defined as an area common for the two populations in relation to the total isotopic space occupied by these populations (proportion; left y-axis) and total community niche (arbitrary units; right y-axis) calculated using pre-bloom and post-bloom datasets...
Spin-isospin rotation dynamicsThe equations for the solitons arbitrarily rotating in the ordinary and isotopic space are obtained....
