Methods in Ecology and Evolution, EarlyView.Abstract Ecologists and evolutionary biologists are increasingly turning to 3D models to use in scientific research. Natural history museums are one of the primary sources for specimens used as 3D models, and efforts are underway to digitize their collections using methods like photogrammetry.

Journal of Fish Biology, EarlyView.Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and
