Classification of the tremendous diversity ray-finned fishes (Actinopterygii) began with designation taxonomic groups on basis morphological similarity. Starting in late 1960s phylogenetics became for classification Actinopterygii but failed to resolve many relationships, particularly among lineages within hyperdiverse Percomorpha. The introduction molecular led a dramatic reconfiguration actinopterygian phylogeny. Refined phylogenetic resolution afforded by studies revealed an uneven...
The teleost family Gobiidae includes at least 1120 described species of fishes, distributed worldwide in both tropical and temperate habitats. majority gobies inhabit marine environments, particular Old World coral reefs. However, a radiation gobiids inhabits the rivers near-shore habitats Europe Asia, variety genera are also found seas New World. This study builds on previous work which were placed among their gobioid relatives by adding additional taxa as well markers, providing much more...
▪ Abstract The proper relationship between systematics practice and our understanding of evolution has been long debated. Systematists seek to avoid assumptions about evolutionary process in their methods, yet a growing body evidence indicates that patterns rates can be used reduce effects homoplasy. We review variable for molecular characters the context constraints on mutation fixation. Some constraints, like genetic code protein-coding genes, are consistent direction effects, whereas...
Antarctic notothenioids are an impressive adaptive radiation. While they share recent common ancestry with several species-depauperate lineages that exhibit a relictual distribution in areas peripheral to the Southern Ocean, understanding of their evolutionary origins and biogeographic history is limited as sister lineage remains unidentified. The phylogenetic placement among major perciform fishes, which include sculpins, rockfishes, sticklebacks, eelpouts, scorpionfishes, perches, groupers...
Abstract Aim To determine biogeographical patterns in five closely related species the fish genus Hypseleotris , and to investigate relative roles of drainage divide crossings movement during lowered sea levels between basins provinces based on phylogeographical within group. The high degree overlap distributions ecology these makes them ideal candidates for comparative study. Location Eastern, central south‐eastern Australia. Methods A total 179 individuals were sequenced from 45 localities...
Abstract Aim To combine a time‐calibrated phylogeny with distributional, fossil and geomorphological data to infer the patterns of lineage origins biogeography among gobies. Location Global marine areas (Indo‐West Pacific, Western Indian Ocean, Mediterranean, Atlantic Eastern Pacific) throughout Cenozoic. Methods I inferred molecular using beast , simultaneously calibrating nodes for Gobiidae, Gobionellidae their combined clade. used that phylogeny, coupled current range data, reconstruct...
The Mediterranean, northeastern Atlantic, and inland freshwaters of Europe the Ponto-Caspian region host a distinct fauna gobiiform fishes, including sand gobies (Pomatoschistus Gill related genera), all which have been classified in most diverse goby group, family Gobiidae. Recent molecular phylogenetic analyses suggested that are not gobiids, instead part their sister clade Gobionellidae (Thacker Roje 2011). Phylogenetic analysis Pomatoschistus context both gobiid gobionellid taxa...
The Pleistocene closure of Isthmus Panama, separating the basins Eastern Pacific and Caribbean Sea, created a unique natural experiment that reveals how marine faunas respond to environmental change. To explore fishes have been affected by this tectonic event, I compare transisthmian patterns in phylogeny morphology for geminate lineages two families, Eleotridae (sleepers) Apogonidae (cardinalfishes).Time-calibrated phylogenies these families show different diversification patterns. In...
A molecular phylogeny using cytochrome c oxidase subunit 1, Histone H3, and 18S rRNA, comprising 3038 aligned characters, was developed for 38 ingroup vetigastropods two neritimorph outgroups. Vetigastropoda is diagnosed by the presence of bursicles their absence in putative vetigastropod groups discussed. The data support monophyly Fissurellidae, Haliotidae, Lepetodrilidae, Pleurotomariidae, Peltospiridae; single exemplar taxa were available Clypeosectidae, Cocculinidae, Neomphalidae,...
Abstract The survival of many organisms depends on interspecific, mutualistic interactions. Hence, it is important to assess the phylogeography multiple species simultaneously gain insight into how their metapopulations persist, spread and recover from disturbance. Consequently, we sequenced mitochondrial DNA (cytochrome b ) a gobiid fish ( Ctenogobiops feroculus its partner, an alpheid snapping shrimp Alpheus djeddensis ). These obligate mutualists are common in shallow coral reef lagoons,...
Elucidating patterns and causes of interaction among mutualistic species is a major focus ecology, recent meta-analyses terrestrial networks show that network-level reciprocal specialization tends to be higher in intimate mutualisms than nonintimate mutualisms. It largely unknown, however, whether this pattern holds for what factors affect marine Here we present the first analysis network ([Formula: see text]) networks. Specialization eight Indo-Pacific obligate gobies shrimps was...
The sand gobies are a group of 30 species in five genera (Knipowitschia, Pomatoschistus, Economidichthys, Ninnigobius and Orsinigobius) native to the seas fresh waters Europe Ponto-Caspian region. We construct phylogeny incorporating new DNA sequence data (mitochondrial COI gene) for Greece Adriatic (Venetian Lagoon) with existing sequences sampled from throughout European waters. Our comprehensive analysis confirms distinctness Orsinigobius Ninnigobius, supports that Gobiusculus is part...
Cleaning symbioses are mutualistic relationships where cleaners remove and consume ectoparasites from their clients. behavior is rare in fishes a highly specialized feeding strategy only observed around 200 species. Cleaner vary degree of specialization, ranging species that clean as juveniles or facultatively adults, to nearly obligate dedicated cleaners. Here, we investigate whether these different levels trophic specialization correspond with similar changes morphology. Specifically,...
The rivers of southeastern Australia host a species complex within the carp gudgeon genus Hypseleotris that includes parental and hemiclonal hybrid lineages. These hemiclones can be difficult to distinguish from their parent taxa, making delineation unusually difficult. We approach this historical taxonomic problem by using single nucleotide polymorphism (SNP) genotyping individuals each hemiclones, enabling us quantify variation among evolutionary lineages assign names species. klunzingeri...
