Hidden Floridian biodiversity: mitochondrial and nuclear gene trees reveal four cryptic species within the scorched mussel, Brachidontes exustus, species complex
The well‐documented Floridian ‘Gulf/Atlantic’ marine genetic disjunction provides an influential example of vicariant cladogenesis along a continental coastline for major elements of a diverseExpand

Phylogenetic structure of the Sphaeriinae, a global clade of freshwater bivalve molluscs, inferred from nuclear (ITS-1) and mitochondrial (16S) ribosomal gene sequences
The Sphaeriidae represent one of the primary molluscan radiations into freshwater environments. We have reconstructed phylogenetic relationships of the Sphaeriinae, a cosmopolitan sphaeriidExpand

E pluribus unum: A phylogenetic and phylogeographic reassessment of Laevapex (Pulmonata: Ancylidae), a North American genus of freshwater limpets.
The North American freshwater limpet genus Laevapex (Walker, 1903) is a ubiquitous inhabitant of lentic and slow-moving lotic habitats east of the Rocky Mountains, but uncertainty clouds itsExpand

Pronounced karyological divergence of the North American congeners Sphaerium rhomboideum and S. occidentale (Bivalvia: Veneroida: Sphaeriidae)
Chromosome sets of two North American sphaeriid species, Sphaerium rhomboideum Say, 1822 and S. occidentale Lewis, 1856, were studied using conventional Giemsa staining and karyometric analysis.Expand

Evolutionary history of a vanishing radiation: isolation-dependent persistence and diversification in Pacific Island partulid tree snails
BackgroundPartulid tree snails are endemic to Pacific high islands and have experienced extraordinary rates of extinction in recent decades. Although they collectively range across a 10,000 km swathExpand

Ecological Release and Venom Evolution of a Predatory Marine Snail at Easter Island
Background Ecological release is coupled with adaptive radiation and ecological diversification yet little is known about the molecular basis of phenotypic changes associated with this phenomenon.Expand

  • 25 September 1999
Spermatogenetic meiosis as well as a very large number of chromosomes (n=76, 2n=ca. 152) were observed in a North American freshwater clam, Sphaerium striatinum. Sphaeriid species studied to date,Expand
