Biodiversity & Macroevolution

Much of my research focuses on the production and survival of biodiversity using the modern and fossil records of animal life. I’ve contributed to work on extinction risk, morphological diveristy, biogeographic dynamics, biological invasions, biomechanics, and the stability of taxonomy. I’m currently working to quantify and understand the morphological dimension of marine bivalve biodiversity using 3D scans of the marine Bivalvia, both ancient and recent. See the projects and papers below for more information.

Bivalve 3D

Admittedly, it’s an ambitious effort to CT scan every living marine bivalve species that occurs along the continental shelf (less than 200m water depth), but we currently stand at ~2500 of 6000 species and counting (and 90% of extant genera!). These 3D models of the bivalve shell are giving us (= Katie Collins, Tingran Gao, Rüdiger Bieler, and David Jablonski) unprecedented access to the variation in bivalve form, and have provided us with the raw material to explore the relationship between this third “currency” of biodiversity and its more commonly studied taxonomic and functional components. We’re especially excited to be developing novel methods for quantifying the complex and diverse forms seen across all of Bivalvia.

Hinge and ecomorphology of Legumen Conrad, 1858 (Bivalvia, Veneridae), and the contraction of venerid morphospace following the end-Cretaceous extinction

The Veneridae are the most speciose modern family of bivalves, and one of the most morphologically conservative and homoplastic, making …

Spatial filters of function and phylogeny determine morphological disparity with latitude

The drivers of latitudinal differences in the phylogenetic and ecological composition of communities are increasingly studied and …

Common latitudinal gradients in functional richness and functional evenness across marine and terrestrial systems

Functional diversity is an important aspect of biodiversity, but its relationship to species diversity in time and space is poorly …

Extinction risk in extant marine species integrating paleontological and biodistributional data

Extinction risk assessments of marine invertebrate species remain scarce, which hinders effective management of marine biodiversity in …

Contrasting responses of functional diversity to major losses in taxonomic diversity

Global biodiversity consists not only of the sum of taxonomic units such as species, but also their ecological or functional variety. …
