Late Jurassic jaw bones of Halecomorph fish (Actinopterygii: Halecomorphi) studied with X-ray microcomputed tomography

, 2015
New finds of Halecomorphi fish remains from Late Jurassic limestones of Owadów-Brzezinki (Poland) are investigated using X-ray microcomputed tomography (XMT) revealing details of jaw bones for actinopterygian fish histology.

Reproductive cycle of native viviparous fish species (Actinopterygii: Cyprinodontiformes: Goodeidae) in a subtropical Mexican lake

Neotropical Ichthyology, 2021
Reproductive tactics and strategies contribute to the persistence and maintenance of long-term populations in fish species. Members of the subfamily Goodeinae are a group of small-bodied freshwater fish with specialized reproduction (viviparity ...

Testing the core–periphery hypothesis: a standardised multi‐phylum assessment of genetic diversity of marine coastal species

Ecography, EarlyView.
The core–periphery hypothesis (CPH) predicts that genetic diversity is greatest at the centre and lowest at the edges of a species' distribution because genetic diversity is a function of a species' abundance, which is also expected to be greatest at the centre and lowest at the edges of the distribution. Variants of the CPH include the ‘Ramped North' (

Population dynamics of an emergent invasive fish, striped piggy, Pomadasys stridens (Actinopterygii, Perciformes, Haemulidae) in the Gulf of İskenderun, north-eastern Mediterranean

, 2021
The striped piggy, Pomadasys stridens (Forsskål, 1775), is a recent invasive fish species in the eastern Mediterranean. Although its population dynamics was investigated in detail in its natural distribution area, the western Indian Ocean, an important ...

The first record of the pharaoh cardinal fish, Apogonichthyoides pharaonis (Actinopterygii: Perciformes: Apogonidae), from Libyan waters

Acta Ichthyologica et Piscatoria, 2021
The occurrence of the pharaoh cardinalfish, Apogonichthyoides pharaonis (Bellotti, 1874), is documented for the first time from the Libyan waters, after two subsequent findings reported in September and November 2020 in the far eastern region of the ...

Sparse genetic data limit biodiversity assessments in protected areas globally

Frontiers in Ecology and the Environment, EarlyView.
Global conservation targets include protecting genetic diversity within species. Yet few studies have assessed whether protected areas (PAs) include genetically diverse populations across species globally. A first step is understanding the availability of population genetic data that could be used in these assessments.

Biological aspects of an interesting fossil fish:Paramblypterus duvernoyi (Amblypteridae, Actinopterygii) [PDF]

Mitteilungen aus dem Museum für Naturkunde in Berlin. Geowissenschaftliche Reihe, 2001
Based on three-dimensional models of the skull and body of Paramblypterus duvernoyi, function of the feeding apparatus and potential of locomotion are interpreted. Compared to most other lower actinopterygians, certain modified features regarding the suspensory apparatus, snout bones, gape, dermohyal and suborbital region, and palaloquadrate-maxillary ...

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.

A Comprehensive Evaluation of Taxonomic Classifiers in Marine Vertebrate eDNA Studies

Molecular Ecology Resources, EarlyView.
ABSTRACT Environmental DNA (eDNA) metabarcoding is a widely used tool for surveying marine vertebrate biodiversity. To this end, many computational tools have been released and a plethora of bioinformatic approaches are used for eDNA‐based community composition analysis.

Chromosome‐Level Genome Assembly of the Loach Goby Rhyacichthys aspro Offers Insights Into Gobioidei Evolution

Molecular Ecology Resources, EarlyView.
ABSTRACT The percomorph fish clade Gobioidei is a suborder that comprises over 2200 species distributed in nearly all aquatic habitats. To understand the genetics underlying their species diversification, we sequenced and annotated the genome of the loach goby, Rhyacichthys aspro, an early‐diverging group, and compared it with nine additional Gobioidei
