Biogeography and Ecological Setting of Indian Ocean Hydrothermal Vents
TLDR
Most organisms found at these Indian Ocean vent fields have evolutionary affinities with western Pacific vent faunas, but a shrimp that ecologically dominates Indian Ocean vents closely resembles its Mid-Atlantic counterpart. Expand
Distinct patterns of genetic differentiation among annelids of eastern Pacific hydrothermal vents
TLDR
Population genetic and phylogenetic analyses of mitochondrial COI from five deep‐sea hydrothermal vent annelids provided insights into their dispersal modes and barriers to gene flow to identify potential dispersal filters in these eastern Pacific ridge systems. Expand
Evolutionary relationships of deep-sea vent and cold seep clams (Mollusca: Vesicomyidae) of the "pacifica/lepta" species complex
TLDR
The present study examined phylogenetic relationships among vesicomyid clams belonging to a cryptic-species complex that includes Vesicomya (previously Calyptogena) pacifica and Vesicomyalepta and found that bathymetric segregation may have played a role in their isolation and divergence. Expand
DISTRIBUTION AND ABUNDANCE OF THE AMAZON RIVER DOLPHIN ( INIA GEOFFRENSIS ) AND THE TUCUXI ( SOTALIA FLUVIATILIS ) IN THE UPPER AMAZON RIVER
A boat survey was conducted from 5 to 26 June 1993 to estimate the abundance of the Amazon river dolphin (Inia geoffrensis) and the tucuxi (Sotalia fluviatilis) along ca. 120 km of the Amazon RiverExpand
Unusual benthic fauna associated with a whale fall in Monterey Canyon, California
On February 6, 2002, we discovered an unusual assemblage of deep-sea animals associated with a well-preserved carcass of a gray whale (Eschrichtius robustus) at 2891 m depth in the axis of MontereyExpand
Contrasting population genetic patterns and evolutionary histories among sympatric Sonoran Desert cactophilic Drosophila
TLDR
Examination of a fragment of the mitochondrial cytochrome oxidase subunit I gene (mtCOI) reveals that the Sea of Cortez has constituted an effective dispersal barrier for D. pachea, leading to significant genetic differentiation between the continental and peninsular ranges of this species. Expand
Population genetics of the swimming crab Callinectes bellicosus (Brachyura: Portunidae) from the eastern Pacific Ocean
TLDR
Maximum-likelihood estimates of long-term effective population size obtained with the program FLUCTUATE, in addition to highly significant values obtained from neutrality tests and mismatch analysis, are consistent with a population expansion dating to the Pleistocene epoch. Expand
Coupling of Bacterial Endosymbiont and Host Mitochondrial Genomes in the Hydrothermal Vent Clam Calyptogena magnifica
TLDR
The tight association between vesicomyid clams and their vertically transmitted bacterial endosymbionts is phylogenetically very young (<50 million years) and may serve as a model for the origin and evolution of eukaryotic organelles. Expand
Phylogeography of Supralittoral Rocky Intertidal Ligia Isopods in the Pacific Region from Central California to Central Mexico
TLDR
The phylogeographic patterns of Ligia in the Gulf of California and Baja peninsula are incongruent with a widely accepted vicariant scenario among phylo geographers, but consistent with aspects of alternative geological hypotheses and phylo- and biogeographical patterns of several other taxa. Expand
Molecular Systematics of the Deep-Sea Hydrothermal Vent Endemic Brachyuran Family Bythograeidae: A Comparison of Three Bayesian Species Tree Methods
Brachyuran crabs of the family Bythograeidae are endemic to deep-sea hydrothermal vents and represent one of the most successful groups of macroinvertebrates that have colonized this extremeExpand
