Culture and conservation in baleen whales. [PDF]

Philos Trans R Soc Lond B Biol Sci
Culture, defined as information or behaviours shared within a population and acquired from conspecifics through social learning, acts as a second inheritance system which has important implications for species' ecology and evolution. Understanding the influence of social learning and culture in animals' lives is essential to planning and predicting ...

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

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.

Morphological variation of the relictual alveolar structures in the mandibles of baleen whales [PDF]

PeerJ, 2021
Living baleen whales (mysticetes) are bulk filter feeders that use keratinous baleen plates to filter food from prey laden water. Extant mysticetes are born entirely edentulous, though they possess tooth buds early in ontogeny, a trait inherited from ...

Marine soundscape variation reveals insights into baleen whales and their environment: a case study in central New Zealand [PDF]

Royal Society Open Science, 2021
Baleen whales reliably produce stereotyped vocalizations, enabling their spatio-temporal distributions to be inferred from acoustic detections. Soundscape analysis provides an integrated approach whereby vocal species, such as baleen whales, are sampled ...

Scaling of maneuvering performance in baleen whales: larger whales outperform expectations. [PDF]

J Exp Biol, 2022
ABSTRACT Despite their enormous size, whales make their living as voracious predators. To catch their much smaller, more maneuverable prey, they have developed several unique locomotor strategies that require high energetic input, high mechanical power output and a surprising degree of agility.

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

Migrating baleen whales transport high-latitude nutrients to tropical and subtropical ecosystems [PDF]

Nature Communications
Baleen whales migrate from productive high-latitude feeding grounds to usually oligotrophic tropical and subtropical reproductive winter grounds, translocating limiting nutrients across ecosystem boundaries in their bodies.

Baleen hormone analyses reveal stress and reproductive life-history of the critically endangered Rice's whale (Balaenoptera ricei). [PDF]

PLoS ONE
The Rice's whale (Balaenoptera ricei) is a recently described species of baleen whale found in the Gulf of Mexico. With fewer than 50 adults remaining, the Rice's whale is the most endangered baleen whale species.

Molecular markers in keratins from Mysticeti whales for species identification of baleen in museum and archaeological collections

PLoS ONE, 2017
Baleen has been harvested by indigenous people for thousands of years, as well as collected by whalers as an additional product of commercial whaling in modern times.

Opportunistic Feeding and Parasite Assemblages in Sei Whales (<i>Balaenoptera borealis</i>) From Southern Chile Revealed by DNA Metabarcoding. [PDF]

Ecol Evol
This study represents the first metabarcoding‐based description of prey composition and parasite‐associated taxa in stranded sei whales from southern South America. ABSTRACT Balaenopterid whales are major consumers in pelagic ecosystems and play a fundamental role in marine food webs.
