Out of the Tropics: Evolutionary Dynamics of the Latitudinal Diversity Gradient
TLDR
A global analysis of genera and subgenera of marine bivalves over the past 11 million years supports an “out of the tropics” model, in which taxa preferentially originate in the Tropics and expand toward the poles without losing their tropical presence. Expand
Marine latitudinal diversity gradients: tests of causal hypotheses.
TLDR
A database of the geographic ranges of 3,916 species of marine prosobranch gastropods living on the shelves of the western Atlantic and eastern Pacific Oceans, from the tropics to the Arctic Ocean, finds diversity gradients are strikingly similar despite many important physical and historical differences between the oceans. Expand
Species Selection: Theory and Data
TLDR
A general formalization of these processes remains challenging, but approaches drawing on hierarchical covariance models appear promising, and analyses integrating paleontological and neontological data for a single set of clades would be especially powerful. Expand
Background and Mass Extinctions: The Alternation of Macroevolutionary Regimes
Comparison of evolutionary patterns among Late Cretaceous marine bivalves and gastropods during times of normal, background levels of extinction and during the end-Cretaceous mass extinctionExpand
Effects of sampling standardization on estimates of Phanerozoic marine diversification
TLDR
A new database of this kind for the Phanerozoic fossil record of marine invertebrates is introduced and four substantially distinct analytical methods that estimate taxonomic diversity by quantifying and correcting for variation through time in the number and nature of inventories are applied. Expand
Larval ecology and macroevolution in marine invertebrates
TLDR
A change in selectivity indicates mass extinctions are not simply intensifications or elltrapoiations of background pro· cesses, but may be indifltrent to the quality of adaptatlon, fitness valuet, or clade confiau· mtions achieved durina background times. Expand
Heritability at the Species Level: Analysis of Geographic Ranges of Cretaceous Mollusks
TLDR
The strong relation between geographic ranges in pairs of closely related species indicates that the trait is, in effect, heritable at the species level, and strengthens claims for processes of evolution by species-level selection, and for differential survivorship of organismic-level traits owing to extinction and origination processes operating at higher levels. Expand
The dynamics of evolutionary stasis
TLDR
Understanding of the fossil record and in population genetics and evolutionary ecology point to the complex geographic structure of species being fundamental to resolution of how taxa can commonly exhibit both short-term evolutionary dynamics and long-term stasis. Expand
Biotic Interactions and Macroevolution: Extensions and Mismatches Across Scales and Levels

  • 1 April 2008
TLDR
Clade dynamics in the fossil record broadly fit expectations from the operation of competition, predation, and mutualism, but data from both modern and ancient systems suggest mismatches across scales and levels, and promising research areas include more realistic approaches to modeling and empirical analysis of large-scale diversity dynamics. Expand
Extinction and the spatial dynamics of biodiversity

  • 12 August 2008
TLDR
The fossil record amply shows that the spatial fabric of extinction has profoundly shaped the biosphere; this spatial dimension provides a powerful context for integration of paleontological and neontological approaches and will be enhanced by partitioning past and present-day extinctions by driving mechanism rather than emphasizing intensity.
