This study maps spatial and temporal overlaps between common dolphin sightings and fishing activity along Portugal's north coast using AIS data and environmental variables.

This study redefines and quantifies close encounters (CEs) between vessels and whales in the Eastern North Atlantic using Time to Potential Collision (TPC) as a dynamic metric, finding that TPC is influenced by species, vessel type, weather, and observer experience.

The paper investigates the evolution of sperm energetics in mammals by analyzing gene duplication and loss of Atp1a4, revealing its role in sodium-dependent glucose uptake and subsequent pseudogenization in three lineages.

The paper introduces GLossDB, a curated database of gene loss events in vertebrates, focusing on cetaceans and other taxa, with searchable features and supporting evidence.

This study uses environmental DNA to characterize cetacean communities and their prey in coastal waters, finding similar results to visual surveys and identifying year-round presence.

The paper examines neuropeptide-receptor gene alterations in cetaceans, finding species-specific mutations and gene loss linked to their unique physiological adaptations.

The paper uses genomic analysis to determine whether the pineal gland in Xenarthra is functional or vestigial, finding that melatonin synthesis and signaling genes are independently eroded and lost.
