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 ...

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.

Diverse baleen whale acoustic occurrence around two sub-Antarctic islands: A tale of residents and visitors [PDF]

Scientific Reports
Knowledge on the occurrence and behaviour of baleen whales around sub-Antarctic regions is limited, and usually based on short, seasonal sighting research from shore or research vessels and whaling records, neither of which provide accurate and ...

A new Early Oligocene toothed ‘baleen’ whale (Mysticeti: Aetiocetidae) from western North America: one of the oldest and the smallest [PDF]

Royal Society Open Science, 2015
Archaic toothed mysticetes represent the evolutionary transition from raptorial to bulk filter feeding in baleen whales. Aetiocetids, in particular, preserve an intermediate morphological stage in which teeth functioned alongside a precursor of baleen ...

A high-resolution 3D reconstructed skeleton of the extinct dwarf whale Cetotherium riabinini from Ukraine [PDF]

Scientific Data
Cetotheres (family Cetotheriidae) were small-sized extinct baleen whales, likely the smallest among toothless baleen whales. Cetotherium riabinini Hofstein, 1948 is known as a single specimen, the holotype.

Surviving a Dark Age: The Oldest Baleen-Bearing Whales (Cetacea: Chaeomysticeti) of Pacific South America (Lower Miocene, Peru) [PDF]

Life
The evolution of baleen whales (Mysticeti) comprises two main phases, namely, (i) a Paleogene phase, which saw the diversification of stem lineages, and (ii) a Neogene phase, dominated by modern-looking, toothless, baleen-bearing forms in the ...

Assessing changing baleen whale distributions and reported incidents relative to vessel activity in the Northwest Atlantic. [PDF]

PLoS ONE
Baleen whales are among the largest marine megafauna, and while mostly well-protected from direct exploitation, they are increasingly affected by vessel traffic, interactions with fisheries, and climate change.

Case studies on longitudinal mercury content in humpback whale (Megaptera novaeangliae) baleen

Heliyon, 2022
Quantification of contaminant concentrations in baleen whales is important for individual and population level health assessments but is difficult due to large migrations and infrequent resighings.

A comparative analysis of extraction protocol performance on degraded mammalian museum specimens

Frontiers in Ecology and Evolution, 2022
The extraction of nucleic acids is one of the most routine procedures used in molecular biology laboratories, yet kit performance may influence the downstream processing of samples, particularly for samples which are degraded, and in low concentrations ...

North Atlantic minke whale (Balaenoptera acutorostrata) feeding habits and migrations evaluated by stable isotope analysis of baleen

Ecology and Evolution, 2021
Isotopic analyses of the incrementally growing baleen in Mysticeti have been used to learn about their feeding and movement patterns. Using methods previously applied to Pacific minke whales, stable δ15N and δ13C isotope values were measured along the ...
