Scale deformities in Nile tilapia, Oreochromis niloticus, (Actinopterygii: Cichlidae) from Sudan [PDF]

Acta Ichthyologica et Piscatoria, 2005
Scale deformity in Nile tilapia, Oreochromis niloticus, (Actinopterygii: Cichlidae) is reported for the first time from Dongola, north of Sudan. The abnormal scales are fused pairs, with two well-developed foci.

Intestinal microbiome richness of coral reef damselfishes (Actinopterygii: Pomacentridae)

Integrative Organismal Biology, 2022
Abstract Fish gastro-intestinal system harbours diverse microbiomes that affect the host’s digestion, nutrition and immunity. Despite the great taxonomic diversity of fish, little is understood about fish microbiome and the factors that determine its structure and composition.

Complete mitogenome sequence of Rasbora argyrotaenia (Actinopterygii: Cyprinidae) [PDF]

Mitochondrial DNA Part B, 2017
The mitochondrial genome of a small freshwater fish Rasbora argyrotaenia from Java Island, Indonesia, was completely sequenced. This mitochondrial genome had 16,740 bp in length and consisted of 37 genes in the typical vertebrate mitochondrial gene arrangement. Phylogenetic analysis showed that R. argyrotaenia is more closely related to R. borapetensis

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

The Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Fish occurrence in the middle Volga and upper Don regions (Russia) [PDF]

Biodiversity Data Journal, 2020
In ichthyological publications from both Russia as a whole, and from the study region, lack of data indicating the actual results of observations in a specific place all result in publication of a generalised analysis.

Trap‐dependence in capture–recapture studies: empirical evidence in vertebrates and biological meaning

Oikos, EarlyView.
Capture–recapture (CR) models have been used for decades to estimate population size and demographic rates in natural populations from the monitoring of individuals. One of the most frequent deviations from assumptions required in CR studies is the immediate trap‐dependence that corresponds to the correlation between capture events. We review empirical

Mobile Elements in Ray-Finned Fish Genomes

Life, 2020
Ray-finned fishes (Actinopterygii) are a very diverse group of vertebrates, encompassing species adapted to live in freshwater and marine environments, from the deep sea to high mountain streams.

Abiotic variables drive different aspects of fish community trait variation and species richness across the continental United States

Journal of Animal Ecology, EarlyView.
Trait distributions provide insight into how niches overlap within a broader trait space. By integrating individual‐level trait observations from different communities, we can explore how facets of trait dimensionality vary across environmental conditions.

Dietary resilience of coral reef fishes to habitat degradation

Journal of Animal Ecology, EarlyView.
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

Refining the Vertebrate Mitochondrial 12S rRNA Secondary Structure by Comparative Analysis

Integrative Zoology, EarlyView.
This flowchart outlines the comprehensive workflow of the study, integrating diverse bioinformatics tools (e.g., NCBI2GO, SSU‐align, bpRNA) and their sequential interactions. Key steps, such as data preprocessing, structural prediction, and evolutionary analysis, are depicted with their respective outputs (e.g., standardized records, consensus ...
