Whale Baleen To Monitor Per- and Polyfluoroalkyl Substances (PFAS) in Marine Environments [PDF]

Environmental Science and Technology Letters
Per- and polyfluoroalkyl substances (PFAS) comprise > 10,000 synthetic compounds that are globally distributed and highly persistent but remain challenging to monitor.

Dynamic filtration in baleen whales: recent discoveries and emerging trends

Frontiers in Marine Science
Recent findings have greatly improved our understanding of mysticete oral filtration, and have upended the traditional view of baleen filtration as a simple process.

Prolonged baleen hormone cycles suggest atypical reproductive endocrinology of female bowhead whales

Royal Society Open Science, 2023
Serial measurements of hormone concentrations along baleen plates allow for reconstructions of mysticete whale reproductive histories. We assessed gestation and calving interval in bowhead whales (Balaena mysticetus) by measuring progesterone, oestradiol,

Assessing the viability of estimating baleen whale abundance from tourist vessels

Frontiers in Marine Science, 2023
Many populations of southern hemisphere baleen whales are recovering and are again becoming dominant consumers in the Southern Ocean. Key to understanding the present and future role of baleen whales in Southern Ocean ecosystems is determining their ...

Baleen–Plastic Interactions Reveal High Risk to All Filter-Feeding Whales from Clogging, Ingestion, and Entanglement

Oceans
Baleen whales are ecosystem sentinels of microplastic pollution. Research indicates that they likely ingest millions of anthropogenic microparticles per day when feeding.

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.

RETRACTED ARTICLE: Lateral palatal foramina do not indicate baleen in fossil whales

Scientific Reports, 2022
Today’s mysticetes filter-feed using baleen, a novel integumentary structure with no apparent homolog in any living mammal. The origins of filter-feeding and baleen can be informed by the fossil record, including rare instances of soft tissue ...

Stable Isotope Oscillations in Whale Baleen Are Linked to Climate Cycles, Which May Reflect Changes in Feeding for Humpback and Southern Right Whales in the Southern Hemisphere

Frontiers in Marine Science, 2022
Baleen whales that undertake extensive long-distance migrations away from reliable food sources must depend on body reserves acquired prior to migration. Prey abundance fluctuates, which has been linked in some regions with climate cycles. However, where

Integrating the needs of recovering populations of baleen whales into the revised management framework for the commercial fishery for Antarctic krill

Frontiers in Marine Science
We consider how the ongoing recovery of baleen whale populations requires improved understanding when managing the largest commercial fishery in the Southern Ocean, the fishery for Antarctic krill.

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.
