From reels to research: Motivations and concerns of billfish citizen science participants
People and Nature, Volume 7, Issue 11, Page 2956-2970, November 2025.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.

Journal of Animal Ecology, Volume 94, Issue 11, Page 2178-2189, November 2025.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
Fish and Fisheries, Volume 26, Issue 6, Page 1164-1179, November 2025.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 ...

Metabarcoding Primers for Indo‐Pacific Fishes
Environmental DNA, Volume 7, Issue 5, September–October 2025.We compared the relative performance of five metabarcoding primers (Berry 16S, Riaz 12S, MiFish E 12S, MiFish U 12S, and Leray CO1) to recover Indo‐Pacific fish taxa. We tested the primers using template DNA from three types of samples: (1) mock communities of tissue‐based DNA extractions, (2) a semi‐natural aquarium tank, and (3) a tropical coral reef

Microsatellites for next-generation ecologists: a post-sequencing bioinformatics pipeline.
PLoS ONE, 2013 Microsatellites are the markers of choice for a variety of population genetic studies. The recent advent of next-generation pyrosequencing has drastically accelerated microsatellite locus discovery by providing a greater amount of DNA sequencing reads at

Blastobasis xiphiae Adamski, new species
, 2013 Blastobasis xiphiae Adamski, new species (Figs. 83–84, 286, 328, Map 10) Diagnosis.— Blastobasis xiphiae is similar to B. iuanae in facies but differs from the latter by having a more protuberant median lobe of the posteroventral margin of the gnathos; a narrower ventral part of the valva; and a narrower proximal flange of the dorsal part of the valva.
