During the last two decades it has become possible to determine the entire DNA content of living organisms—the genome. The completion of the human reference DNA sequence has provided an enormous amount of DNA sequence data and has extended our view of the genetic bases of disease....

Species Groups

A review of the taxonomy, phylogeny, and zoogeography of all currently recognized Gekko species is provided based on morphology (including size, scalation, color, and pattern) and mitochondrial and nuclear DNA sequence data. We distinguish six morphological (phenotypic) species groups within the gekkonid genus Gekko: the G. gecko, G. japonicus, G. monarchus, G. petricolus, G. porosus, and G. vittatus groups, all of which receive support from molecular phylogenetics. The taxon G. reevesii, formerly evaluated as a synonym of G. gekko, is revalidated herein at specific rank. Furthermore, a preliminary identification key of all currently recognized Gekko taxa is provided.

Thoracophelia (Annelida, Opheliidae) are burrowing deposit feeders generally found in the mid- to upper intertidal areas of sandy beaches. Thoracophelia mucronata (Treadwell, 1914) is found along the west coast of North America, including at Dillon Beach, CA. Two additional species, Thoracophelia dillonensis (Hartman, 1938) and T. williamsi (Hartman, 1938) were also described from this beach. These three sympatric species have been primarily distinguished by branchial morphology, and efforts to determine the validity of the species have been based on morphological, reproductive and ecological studies. Here we demonstrate using mitochondrial and nuclear DNA sequence data that these three species are valid. Mitochondrial Cytochrome c subunit 1 (COI) sequences show uncorrected interspecific distances of ~9–13%. We found no inter—specific differences in body color or in hemoglobin concentration, but found that reproductive males were pinkish-red in color and had lower hemoglobin concentrations than purplish—red reproductive females.

Disjunct Genus

A phylogenetic study testing the monophyly of the geographically disjunct genus Ronnbergia (Bromeliaceae, Bromelioideae) is presented. The phylogenetic analyses were based on taxon sampling that included all but one species of Ronnbergia, and representative lineages across the subfamily Bromelioideae. Three chloroplast DNA sequence markers (matK, psbA-trnH, and trnL-trnF) and morphological data were used for the phylogenetic reconstruction. Both the molecular and morphological datasets supported the polyphyly of Ronnbergia, either independently or in combination. These findings suggest that the geographic disjunction of this genus is most likely a product of taxonomic misinterpretation. The results also indicate that the species currently circumscribed in Ronnbergia are closely related to species in the genus Aechmea with similar geographic ranges. The datasets do not have enough resolution power to reconstruct a deep phylogenetic history that involves all the species of Ronnbergia. Nevertheless, this study provides clues for future approaches that should focus on a larger species sampling and the use of multi-locus DNA sequence data.
