BALDWIN AND G. DAVID JOHNSON Paxtonconcilians is described as a new genus and species of pseudamineapogonid from four specimens trawled off northwesternAustralia. It differs most conspicu- ously from all other apogonids in having a continuous dorsal fin but shares with other members of the family certain specializationsof the dorsal gill arches, last spinous dorsal fin pterygiophore,and cutaneous sensory system. We recognize two subfamiliesof apogonids, the Apogoninaeand Pseudaminae,and diagnosethe latter on the basis of numerous derived features. We propose that Paxtonbe added as a fourth member of the Pseudaminae(with Gymnapogon,Pseudamia, and Pseudamiops) and provide strong evidence that Paxtonis the sister group of Gymnapogon,a taxon whose phylogeneticposition withinthe Apogonidaehas never been well understood.

The species and size composition of the fish fauna and their trophic interactions were studied for five stations. Samples were collected during 5–6 consecutive days close to spring tide in mid-July 2011. Fish were caught using different types of passive fishing gear, such as large and small fyke nets, gill nets and, additionally, beach seines. All individuals were identified to species level, measured and preserved for further analyses. Stomach content analysis was applied to provide information about their diet. Stable isotope analysis was used to detect whether the source of primary production for the higher trophic levels is mangrove-related or not. A total of 27 fish species was recorded in a catch of 938 teleost speci- mens.

Abstract A checklist of shallow (to 60 m depth) reef fishes is provided for the Bird’s Head Peninsula region of West Papua, Indonesia. The area, which occupies the extreme western end of New Guinea, contains the world’s most diverse assemblage of coral reef fishes. The current checklist, which includes both historical records and recent survey results, includes 1,511 species in 451 genera and 111 families. Respective species totals for the three main coral reef areas – Raja Ampat Islands, Fakfak-Kaimana coast, and Cenderawasih Bay – are 1320, 995, and 877. In addition to its extraordinary species diversity, the region exhibits a remarkable level of endemism considering its relatively small area. A total of 26 species in 14 families are currently considered to be confined to the region. Introduction and finally a complex geologic past highlighted The region consisting of eastern Indonesia, East by shifting island arcs, oceanic plate collisions, Timor, Sabah, Philippines, Papua New Guinea, and widely fluctuating sea levels (Polhemus and the Solomon Islands is the global centre of 2007). reef fish diversity (Allen 2008).

    Quantitative Species-Level Ecology of Reef Fish Larvae Via Metabarcoding

    ARTICLES https://doi.org/10.1038/s41559-017-0413-2 Quantitative species-level ecology of reef fish larvae via metabarcoding Naama Kimmerling1,2, Omer Zuqert3, Gil Amitai3, Tamara Gurevich2, Rachel Armoza-Zvuloni2,8, Irina Kolesnikov2, Igal Berenshtein1,2, Sarah Melamed3, Shlomit Gilad4, Sima Benjamin4, Asaph Rivlin2, Moti Ohavia2, Claire B. Paris 5, Roi Holzman 2,6*, Moshe Kiflawi 2,7* and Rotem Sorek 3* The larval pool of coral reef fish has a crucial role in the dynamics of adult fish populations. However, large-scale species-level monitoring of species-rich larval pools has been technically impractical. Here, we use high-throughput metabarcoding to study larval ecology in the Gulf of Aqaba, a region that is inhabited by >500 reef fish species. We analysed 9,933 larvae from 383 samples that were stratified over sites, depth and time. Metagenomic DNA extracted from pooled larvae was matched to a mitochondrial cytochrome c oxidase subunit I barcode database compiled for 77% of known fish species within this region. This yielded species-level reconstruction of the larval community, allowing robust estimation of larval spatio-temporal distribu- tions. We found significant correlations between species abundance in the larval pool and in local adult assemblages, suggest- ing a major role for larval supply in determining local adult densities. We documented larval flux of species whose adults were never documented in the region, suggesting environmental filtering as the reason for the absence of these species. Larvae of several deep-sea fishes were found in shallow waters, supporting their dispersal over shallow bathymetries, potentially allow- ing Lessepsian migration into the Mediterranean Sea.

    State of research of the Osteichthyes fish related to coral reefs in the Honduran Caribbean with catalogued records Estado del conocimiento de los peces osteíctios asociados a los arrecifes de coral en el Caribe de Honduras, con registros catalogados Anarda Isabel Salgado Ordoñez1, Julio Enrique Mérida Colindres1* & Gustavo Adolfo Cruz1 ABSTRACT Research on Honduran coral reef fish has been isolated and scattered. A list of fish species related to coral reefs was consolidated to establish a compiled database with updated taxonomy. The study was conducted between October 2017 and December 2018. Using primary and secondary sources, all potential species in the Western Atlantic were considered, and their actual presence was confirmed using catalogued records published in peer-reviewed journals that included Honduras. In addition, the specimens kept in the Museum of Natural History of Universidad Nacional Autónoma de Honduras were added. Once the list was consolidated, the taxonomic status of each species was updated based on recent literature. A total of 159 species and 76 genera were registered in 32 families. The family with the most species was Labrisomidae with 27 species (17%). Five families had more than five 5 genera registered, while four 4 were represented by more than 16 species, which is equivalent to 42% genera and 51% species. Gobiidae was represented by 10 genera (13%) and 21 species (13%), of which two 2 were endemic: Tigrigobius rubrigenis and Elacatinus lobeli. In turn, Grammatidae was represented by one endemic species Lipogramma idabeli (1.8%). The species Diodon holocanthus and Sphoeroides testudineus represent the first catalogued records for Honduras.

He de admitir que el hecho me impresionó, pues ponía al descubierto toda una serie de oscuras caren- cias que marcaron un propósito a seguir en la disciplina que me ha ocupado durante treinta años: la ictiología.

Abstract A checklist of shallow (to 60 m depth) reef fishes is provided for the Bird’s Head Peninsula region of West Papua, Indonesia. The area, which occupies the extreme western end of New Guinea, contains the world’s most diverse assemblage of coral reef fishes. The current checklist, which includes both historical records and recent survey results, includes 1,511 species in 451 genera and 111 families. Respective species totals for the three main coral reef areas – Raja Ampat Islands, Fakfak-Kaimana coast, and Cenderawasih Bay – are 1320, 995, and 877. In addition to its extraordinary species diversity, the region exhibits a remarkable level of endemism considering its relatively small area. A total of 26 species in 14 families are currently considered to be confined to the region. Introduction and finally a complex geologic past highlighted The region consisting of eastern Indonesia, East by shifting island arcs, oceanic plate collisions, Timor, Sabah, Philippines, Papua New Guinea, and widely fluctuating sea levels (Polhemus and the Solomon Islands is the global centre of 2007). reef fish diversity (Allen 2008). Approximately 2,460 species or 60 percent of the entire reef fish The Bird’s Head Peninsula and surrounding fauna of the Indo-West Pacific inhabits this waters has attracted the attention of naturalists and region, which is commonly referred to as the scientists ever since it was first visited by Coral Triangle (CT).
