When Similar Individuals Don't Attract: Absence of Assortative Mating by Coloration in a Damselfly With Honest Signaling

Ethology, EarlyView.
In Acanthagrion lancea damselflies, both sexes display blue ornamentation, but do they choose mates based on it? We tested whether mutual mate choice and time constraints influence ornament evolution. Blue coloration correlated with individual quality, but individuals did not choose mates based on color, and this was unaffected by time constraints over

Global Analysis of Shallow Underwater Fish Observation Research: 70 Years of Progress, Persistent Geographic Biases and a Path Forward

Fish and Fisheries, EarlyView.
ABSTRACT Marine ecosystems are increasingly threatened by overfishing, pollution, coastal development and climate change, underscoring the need for long‐term, representative information on key fish populations and habitats to inform management and policy.

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

Journal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Northern cod (Gadus morhua) movement: insights from acoustic telemetry and genomics

Journal of Fish Biology, EarlyView.
Abstract Knowledge of the timing and diversity of fish movements within a commercially exploited stock complex is required to ensure the sustainability of fisheries. Although migration can be driven by environmental factors, genomic mechanisms also play an important role in this complex life‐history trait. The northern cod (Gadus morhua) stock complex,
