Sexing From Seawater: Application of Environmental DNA Beyond Species Detection for Cetaceans

open access: yesEnvironmental DNA
Anthropogenic pressures on marine ecosystems are intensifying, highlighting the need to bridge knowledge gaps for species at risk. Data deficiencies, particularly for species recovering from historic declines, such as marine megafauna like whales, hinder

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

open access: yesThe Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

Abundance of whales in West and East Greenland in summer 2015

open access: yesNAMMCO Scientific Publications, 2019
An aerial line transect survey of whales in West and East Greenland was conducted in August-September 2015. The survey covered the area between the coast of West Greenland and offshore (up to 100 km) to the shelf break.

Groundtruthing of pelagic forage fish detected by hydroacoustics in a whale feeding area using environmental DNA

open access: yesEnvironmental DNA, 2020
Conservation of whales, considered as umbrella species in marine environments, requires to be able to understand their relationships with ecosystem components such as prey species, including pelagic fish. However, studying such relationships in nature is

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds

open access: yesThe Anatomical Record, EarlyView.
Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.

A geometric morphometric approach for detecting different reproductive stages of a free-ranging killer whale Orcinus orca population

open access: yesScientific Reports
The expansion of drone-based aerial imagery has facilitated an increase in data obtained from free-ranging marine mammal populations, in particular cetacean species.

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Assessing social behaviour between baleen whales (Mysticeti) and dolphins (Delphinidae)

open access: yesDiscover Animals
The dynamics and factors influencing interspecies interactions in the wild are not well understood, particularly among social marine animal species such as Mysticetes and Delphinadae.

Neuroanatomy of the Cetacean Sensory Systems

open access: yesAnimals, 2023
Cetaceans have undergone profound sensory adaptations in response to their aquatic environment during evolution. These adaptations are characterised by anatomo-functional changes in the classically defined sensory systems, shaping their neuroanatomy ...
