Characterizing the Duration and Severity of Fishing Gear Entanglement on a North Atlantic Right Whale (Eubalaena glacialis) Using Stable Isotopes, Steroid and Thyroid Hormones in Baleen

Frontiers in Marine Science, 2018
North Atlantic right whales (Eubalaena glacialis) are highly endangered and frequently exposed to a myriad of human activities and stressors in their industrialized habitat. Entanglements in fixed fishing gear represent a particularly pervasive and often

Severe Bone Loss as Part of the Life History Strategy of Bowhead Whales. [PDF]

PLoS ONE, 2016
The evolution of baleen constituted a major evolutionary change that made it possible for baleen whales to reach enormous body sizes while filter feeding on tiny organisms and migrating over tremendous distances.

Reconstructing the diet, trophic level and migration pattern of mysticete whales based on baleen isotopic composition

Royal Society Open Science, 2021
Baleen from mysticete whales is a well-preserved proteinaceous material that can be used to identify migrations and feeding habits for species whose migration pathways are unknown. Analysis of δ13C and δ15N values from bulk baleen have been used to infer

First filter feeding in the Early Triassic: cranial morphological convergence between Hupehsuchus and baleen whales

BMC Ecology and Evolution, 2023
Modern baleen whales are unique as large-sized filter feeders, but their roles were replicated much earlier by diverse marine reptiles of the Mesozoic.

Advancing baleen whale acoustic and habitat monitoring in the Northwest Atlantic

, 2022
Baleen whales of the Northwest Atlantic live in an urbanized ocean. They attempt a slow recovery from commercial whaling amid threats from the infrastructure, pollution, and shifting environmental baseline associated with human exploitation of the ...

Rostrum morphology and feeding strategy of the baleen whale indicate that right whales and pygmy right whales became skimmers independently

Royal Society Open Science, 2022
Baleen whales have lost their functional teeth and begun to use their baleen plates to feed on small prey. Modern baleen whales exhibit different types of feeding strategies, such as lunging, skimming and so on.

Scaling of swimming performance in baleen whales [PDF]

Journal of Experimental Biology, 2019
The scale-dependence of locomotor factors have long been studied in comparative biomechanics, but remain poorly understood for animals at the upper extremes of body size. Rorqual baleen whales include the largest animals, but we lack basic kinematic data about their movements and behavior below the ocean surface.

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

Journal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...
