Global Marine Fishery Stock Productivity Under Climate Change
In this uniquely extensive global analysis on the productivity of commercial fishery stocks, a common factor was the existence of pronounced heterogeneity, as documented for 710 stocks in the undertaken hindcast over the last decades. Importantly, both winners and losers appear under on‐going climate change, and then seemingly are equally present ...

ABSTRACT In this study, we explored the population genetic structure and its relation to environmental adaptations of the dolphinfish (Coryphaena hippurus) in the western Atlantic Ocean and Mediterranean Sea. Although previously two populations within the Mediterranean Sea were identified, recent evidence suggests more complex structuring.

From reels to research: Motivations and concerns of billfish citizen science participants
Abstract Citizen science facilitates cost‐effective ecological data collection at much larger scales than would otherwise be feasible. This is particularly useful for the study of highly migratory species with broad distributions, such as billfishes.

The mitochondrial genome of the swordfish, Xiphias gladius
The order Istiophoriformes is composed of bony fishes with major morphological, physiological, behavioral, and ecological differences. Among them, billfishes, characterized by the presence of a snout resembling a sword, are contained in the families Xiphiidae and Istiophoridae.

We show that regionally endothermic shortfin mako sharks have enhanced thermoregulatory ability with an order higher warming rate than cooling rate during repeated dives, likely optimizing foraging efficiency. This ability, only comparable to bigeye tuna and swordfish in teleosts, represents the key adaptive significance of regional endothermy in ...

Into the Deep: Origins and Evolution of Northeastern Pacific Ocean Tuna (Thunnus spp.) Fisheries
ABSTRACT People have had a profound influence on Earth's biodiversity for millennia, culminating in Anthropocene environmental degradation and the modern biodiversity crisis. While the scale and extent of people's long‐term influence on Earth's biodiversity in terrestrial and nearshore marine ecosystems are relatively well studied, there are ...

Mixture models are in high demand for machine-learning analysis due to their computational tractability, and because they serve as a good approximation for continuous densities.
