Randomized trial assesses community inertia in mammalian assemblages over nearly one million years, suggesting deterministic influences.

This research investigates whether community inertia occurs in biotic communities over extensive time and geographical scales.
Examined fossil assemblages across nearly 1,000,000 years
Studied sites spanning approximately 3,500 km
Applied neutral theory to establish reference points for inertia measurement
Demonstrated significant evidence for community inertia over time scales greater than 3,000 years
Empirical mammalian communities showed greater inertia than neutral communities
Results varied with taxonomic, spatial, and temporal scales

McGill et al. (2005) studied this question.
