TL;DR: The first record of the presence of microplastics in the digestive tracts of marine mammals from the Iberian Peninsula is made, with an average of 12 items per stomach although abundance varied widely from one stomach to another.

TL;DR: In this paper, the authors developed an alternative approach consisting of: (1) collating diverse survey data to maximise spatial and temporal coverage, (2) using detection functions to estimate variation in the surface area covered (km2) among these surveys, standardising measurements of effort and animal densities, and (3) developing species distribution models (SDM) that overcome issues with heterogeneous and uneven coverage.

TL;DR: Estimates and confidence limits, taking into account sampling error, for consumption of fish by the four most common cetaceans along the Atlantic coast of the Iberian Peninsula are provided, while highlighting the uncertainties and biases inherent in the information presently available on energy requirements, diet and population size.

TL;DR: The results indicate that common dolphins are mainly piscivorous, feeding mostly on mesopelagic prey, and the narrow continental shelf seems to facilitate the availability of Myctophids and other members of the mesopalagic assemblages to dolphins when the assemblage migrates to the surface at night.

TL;DR: In this article, a large number of surveys provided the first basin-wide models of distribution for deep-diving cetaceans across the North Atlantic Ocean and the Mediterranean Sea.
