Selectivity of mass extinctions is thought to play a major role in coupling or decoupling of
taxonomic, morphological, and ecological diversity, yet these measures have never been …

Origins of higher taxonomic groups entail dramatic and nearly simultaneous changes in
morphology and ecological function, limiting our ability to disentangle the drivers of …

Recent advances in statistical approaches called phylogenetic comparative methods
(PCMs) have provided paleontologists with a powerful set of analytical tools for investigating …

Between the late Cambrian and Late Ordovician, significant changes occurred in faunal
diversity, ecosystem assembly, sedimentary motifs, and oceanic/climate systems. The …

Ordovician open marine Lagerstätten are relatively rare and widely dispersed, producing a
patchy picture of the diversity and biogeography of nonmineralized marine organisms and …

The quantification of morphology through time is a vital tool in elucidating macroevolutionary
patterns. Studies of disparity require intense effort but can provide insights beyond those …

The echinoderms are an ideal group to understand evolution from a holistic, interdisciplinary
framework. The genetic regulatory networks underpinning development in echinoderms are …

Abstract The Cambrian and Ordovician radiations marked the origins of all major
echinoderm clades and established their Phanerozoic ecological blueprint. Recent claims of …

Understanding the roles of habitat filtering, dispersal limitations and biotic interactions in
sha** the organization of animal communities is a central research goal in ecology …

Identifying correlates of extinction risk is important for understanding the underlying
mechanisms driving differential rates of extinction and variability in the temporal durations of …
