Oyster (Ostrea edulis) extirpation and ecosystem transformation in the Firth of Forth, Scotland (2013, unknown): “004 ures of species richness and/or biomass, whilst time averaging may increase perceived species richness as species from different layers of sediment become mixed together over time (Kidwell 2002).”
Consequences of dominance: a review of evenness effects on local and regional ecosystem processes. (2008, background): “Recent paleoecological evidence indicates that fossil abundance data reflect real abundance distributions (Kidwell 2001, 2002); thus, we might expect to learn more about the climate-related shifts in evenness over long time scales (Powell and Kowalewski 2002).”
Fidelity of variation in species composition and diversity partitioning by death assemblages: time-averaging transfers diversity from beta to alpha levels (2009, background): “The same mechanism predicted to reduce variation in species composition in DAs has also been assumed to underlie the excess of within-habitat alpha diversity observed in molluscan death assemblages, even after sample size-standardization (Kidwell 2002, 2007, 2008; Olszewski and Kidwell 2007).”
On raptors and rodents: testing the ecological fidelity and spatiotemporal resolution of cave death assemblages (2010, background): “The majority of live-dead studies have focused on shelled mollusks in soft-sediment environments (see meta-analysis of Kidwell 2001, 2002a,b; Olszewski and Kidwell 2007).”
Predicting the effects of increasing temporal scale on species composition, diversity, and rank-abundance distributions (2010, background): “First, alpha diversity of timeaveraged death assemblages at habitat scales commonly exceeds that of counterpart living assemblages (Kidwell 2001, 2002; Lockwood and Chastant 2006; Olszewski and Kidwell 2007; for foraminiferal examples, see Murray 2003; Horton and Murray 2006).”
Probabilistic historical biogeography: new models for founder-event speciation, imperfect detection, and fossils allow improved accuracy and model-testing (2013, unknown): “ First, there is a rich literature comparing species abundances in fossil and living assemblages (e.g., Kidwell 2001; Kidwell 2002; Kidwell & Holland 2002; Vermeij & Herbert 2004; Moore, Norman & Upchurch 2007; Terry 2010; Turvey & Blackburn 2011); if a…”
The preservational fidelity of evenness in molluscan death assemblages (2007, background): “Kidwell (2002a) postulated that excess dead richness despite the high fidelity of rank order in death assemblages could reflect the tendency for the most numerically abundant species in the living assemblage to be relatively small bodied, even as adults, making them particularly susceptible to…”
Quantitative Fidelity of Brachiopod-Mollusk Assemblages from Modern Subtidal Environments of San Juan Islands, USA (2003, result): “This observation is consistent with the general tendency of death assemblages to be dominated by remains of organisms that died recently (see also Olszewski, 1999; Kidwell, 2002).”
