Comparative Satellitomics in Arowanas (Telostei, Osteoglossiformes) Sheds Light on the Evolution of Ancient Satellite DNAs

Integrative Zoology, EarlyView.
This work focused on arowana fishes (Teleostei, Osteoglossiformes) as a model; their widespread intercontinental distribution and basal phylogenetic position within Teleostei make them a compelling model for evolutionary research, especially in the realm of satDNA molecular evolution. Through the integration of genomic and chromosomal data, we analyzed

Extralimital sightings of a gray whale in the western North Atlantic

Endangered Species Research
Gray whales Eschrichtius robustus are High Arctic migrants that primarily inhabit the North Pacific Ocean. Gray whales have been extirpated from the North Atlantic Ocean since at least the middle of the 18th century.

Geographic Patterns of Head Morphology in Syngnathus typhle Across Marine Regions

Integrative Zoology, EarlyView.
Morphometric analysis of Syngnathus typhle head shape shows distinct geographic patterns across Baltic, North, Atlantic, and Mediterranean marine regions, driven by variation in snout length, head depth, and eye position. Findings provide a non‐invasive baseline for conservation monitoring.

Transcriptomics Unveil Dsx1 as a Critical Regulator in Sexual Dimorphism of Crustaceans

Integrative Zoology, EarlyView.
Sexually dimorphic traits are involved in reproductive competition and are shaped by sex‐biased gene expression. This study identifies Dsx1 as a key male‐biased gene in Morinoia aosen and demonstrates through RNA interference that its disruption feminizes male‐specific T3 leg structures.

From fluke to fragment: A multifaceted method for molecular sex identification and mitochondrial haplotyping from environmental DNA samples

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental DNA (eDNA) analyses have become a powerful tool for non‐invasive biodiversity monitoring, yet the applicability of population‐genetic approaches to environmental samples remains largely unexplored. Even when genetic traces originate from a single individual, low target DNA concentrations and amplification or sequencing artefacts ...

Prey Partitioning in a Diverse Carnivore Community: Implications for Reintroduced Fishers in Washington

Animal Conservation, EarlyView.
Using fecal DNA metabarcoding, we quantified dietary overlap among reintroduced fishers and sympatric coyotes, bobcats, and Pacific martens in Washington's North Cascades. Niche overlap was substantial for common prey but varied with body size, revealing fine‐scale resource partitioning that may limit fishers' access to energetically efficient prey ...

Tipping the Scales Using Cryopreservation: Modelling the Genetic Value and Management Potential of Integrated Cryopreservation for Threatened Ex‐Situ Pupfish Populations

Animal Conservation, EarlyView.
This graphical abstract depicts the number of additional fish that would be required to achieve 90% genetic diversity for endangered pupfish species housed in EAZA collections, with or without the use of cryopreserved material. ABSTRACT Zoos and aquaria must retain genetic diversity for the species they house if the populations are to remain viable ...

The First Record of Argulus Foliacesus (Crustacea: Branchiura) Infesta­tion on Lionhead Goldfish (Carassius Auratus) in Iran [PDF]

Iranian Journal of Parasitology, 2010
Argulus foliaceus (Crustacea: Branchiura), or the fish louse, is an ectoparasite of the skin or gill of the fresh water fish species. Clinical signs in infected fish include scratching on aquarium walls, erratic swimming, and poor growth.
