n. sp., a new wrasse from the Revillagigedo Archipelago of Mexico, tropical eastern Pacific Ocean (Teleostei: Labridae).

A new labrid fish species, n. sp., is described from eight specimens collected in the Revillagigedo Archipelago in the tropical eastern Pacific Ocean, off the coast of Mexico.

Stance detection with BERT embeddings for credibility analysis of information on social media.

The evolution of electronic media is a mixed blessing. Due to the easy access, low cost, and faster reach of the information, people search out and devour news from online social networks. In contrast, the increasing acceptance of social media reporting leads to the spread of fake news.

An Indo-Pacific damselfish () in the Gulf of Mexico: origin and mode of introduction.

The Indo-West Pacific (IWP) coral-reef damselfish is well established across the south-west Gulf of Mexico (SwGoMx). Comparisons of mtDNA sequences of the SwGoMx population with those from conspecifics from 16 sites scattered across its native geographic range show that the SwGoMx population is derived from two of four native lineages: one from the north-west Pacific Ocean, the other from the northern Indian Ocean. Three hypotheses address how this species was introduced to the SwGoMX: (1) aquarium release; (2) borne by cargo-ship; and (3) carried by offshore petroleum platform (petro-platform).

Catalog of the phylloxerids of the world (Hemiptera, Phylloxeridae).

A taxonomic and nomenclatural catalog of the phylloxerids (Hemiptera, Phylloxeridae) is presented. Six family-group names are listed, three being synonyms. Thirty-five genus-group names, of which six are subjectively valid, are presented with their type species, etymology, and grammatical gender.

Catalog of the adelgids of the world (Hemiptera, Adelgidae).

A taxonomic and nomenclatural Catalogue of the adelgids (Hemiptera: Adelgidae) is presented. Six family-group names are listed, five being synonyms of Adelgidae. Twenty-two genus-group names, of which nine are subjectively valid and in use, are presented with their type species, etymology, and grammatical gender.

Rebuttal to Koeda et al. (2014) on the Red Sea fishes of the perciform genus Pempheris.

Koeda et al. (2014) published a review of fishes of the genus Pempheris of the Red Sea. They concluded that there are four species: P.

Rediscovery of Sagittalarva inornata n. gen., n. comb. (Gilbert, 1890) (Perciformes: Labridae), a long-lost deepwater fish from the eastern Pacific Ocean: a case study of a forensic approach to taxonomy using DNA barcoding.

Some of the more valuable contributions of a standardized DNA sequence database (the DNA barcode) are matching specimens of different life stages and confirming the species identity of individuals from distant locations. These applications can facilitate the detective work required to solve difficult taxonomic problems. In this case, a match was made between the COI mtDNA sequence of an adult male wrasse recently caught at the tip of Baja California in Mexico in deep water (30-100m) and sequences from a series of unusual larvae collected about 3500 km to the south, in the open ocean over the Galápagos Rift hydrothermal vents in 1985.

Seven new species within western Atlantic Starksia atlantica, S. lepicoelia, and S. sluiteri (Teleostei, Labrisomidae), with comments on congruence of DNA barcodes and species.

Specimens of Starksia were collected throughout the western Atlantic, and a 650-bp portion of the mitochondrial gene cytochrome oxidase-c subunit I (COl) was sequenced as part of a re-analysis of species diversity of western Central Atlantic shorefishes. A neighbor-joining tree constructed from the sequence data suggests the existence of several cryptic species. Voucher specimens from each genetically distinct lineage and color photographs of vouchers taken prior to dissection and preservation were examined for diagnostic morphological characters.

Mechanisms of speciation and faunal enrichment in Atlantic parrotfishes.

Relationships based on mtDNA and nDNA sequences were used to assess effects of two major geographic barriers (the >30 myo Atlantic ocean and the approximately 11 myo Amazon-Orinoco outflow) on speciation among Atlantic parrotfishes (Sparisoma and Nicholsina). Allopatric distributions of sister taxa implicate isolating actions of both barriers in all recent speciation in these fishes, with no clear indications that any speciation resulted from other mechanisms. Molecular clock estimates of the timing of lineage splits indicate that both barriers acted by limiting dispersal well after they formed, although the Amazon barrier also may have been a vicariance agent.

El Niño mass coral mortality: a test of resource limitation in a coral reef damselfish population.

The mass mortality of reef corals in the eastern Pacific as a result of the 1982-1983 El Niño oceanographic anomaly permitted the first large scale test of resource limitation for a coral reef fish. Population densities of territorial herbivorous damselfish did not respond to the massive regional increase in space available for the cultivation of algal food following the El Niño event. The proportion of juveniles in the population was low and new recruits were uncommon, indicating that recruitment rates rather than resource supply probably control the abundance of this coral reef damselfish.
