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 ...

The Diversity of Ray-finned Fishes (Actinopterygii) in Plio-Pleistocene Java

Journal of Tropical Biodiversity and Biotechnology, 2020
Java has been known in the world of Paleontology as a contributor to the findings of Homo erectus fossils, but there are still other fossil findings that have not been identified until now, especially fossil fishes of the subclass Actinopterygii. This research was conducted to recognize the diversity of the actinopterygians fishes in Plio-Pleistocene ...

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

Feeding behavior of the Amazonian Water Snake Helicops hagmanni Roux, 1910 (Reptilia: Squamata: Colubridae: Hydropsini) [PDF]

Boletim do Museu Paraense Emílio Goeldi. Ciências Naturais, 2008
The genus Helicops currently comprises 15 species, of which eleven occur in the Amazon Forest. H. hagmanni feeds on fishes and has nocturnal habits, but detailed data about its diet and behavioral ecology are scarce. Here, we report a H.

Toltrazuril (Baycox® vet.) in feed can reduce Ichthyophthirius multifiliis invasion of rainbow trout (Salmonidae) [PDF]

Acta Ichthyologica et Piscatoria, 2011
Various compounds have been applied for control of Ichthyophthirius multifiliis (commonly known as Ich) which is the parasitic pathogen, responsible for the white spot disease, in freshwater aquaculture worldwide.  Available methods are based on

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 ...

New pycnodontiform fishes (Actinopterygii, Neopterygii) from the Early Cretaceous of the Argentinian Patagonia [PDF]

Cretaceous Research, 2019
Here we describe new pycnodontiform fish material recovered from the marine Agrio Formation (lower Valanginian-lower Hauterivian) of the Neuquén Province in the south-western of Patagonia, Argentina. The new material include an incomplete skull and an incomplete prearticular dentition.
