Rank-abundance curves (RACs) quantify changes in community structure during periods of stress (which may or may not result in extinction). To determine the sensitivity of RACs to biotic responses at different temporal resolutions (i.e., the effects of time-averaging on fossil communities), RACs...

Univariate and multivariate methods are commonly used to explore the spatial and temporal dynamics of ecological communities, but each has limitations, including oversimplification or abstraction of communities. Rank abundance curves (RACs) potentially integrate these existing methodologies by detailing species...
QUANTIFYING ECOLOGICAL RESPONSE TO CLIMATE CHANGE: USING RANK-ABUNDANCE CURVES OF MICRO-BENTHIC COMMUNITIES DURING THE PALEOCENE-EOCENE THERMAL MAXIMUMTo map ecological effects of the PETM on deep-ocean benthic communities, RAC-derived curve-area and kurtosis values were calcul...
