Functional variants of the melanocortin-4 receptor associated with the Odontoceti and Mysticeti suborders of cetaceans

open access: yesScientific Reports, 2017
Cetaceans, a group of mammals adapted to the aquatic environment that descended from terrestrial artiodactyls, exhibit tremendous interspecific differences in a number of phenotypes, including feeding behavior, such as filter feeding in the Mysticeti vs ...

Like phoenix from the ashes: How modern baleen whales arose from a fossil “dark age” [PDF]

open access: yesActa Palaeontologica Polonica, 2019
The evolution of baleen whales (Mysticeti), the largest animals on Earth, was punctuated by a pivotal turnover event. Following their emergence around 36 million years (Ma), mysticetes diversified into a disparate range of toothed and toothless species ...

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

open access: yesEcology 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 ...

Comparative chromosome painting discloses homologous Segments in distantly related mammals [PDF]

open access: yes, 1994
Comparative chromosome painting, termed ZOO-FISH, using DNA libraries from flow sorted human chromosomes 1,16,17 and X, and mouse chromosome 11 discloses the presence of syntenic groups in distantly related mammalian Orders ranging from primates (Homo

Big and Slow: Phylogenetic Estimates of Molecular Evolution in Baleen Whales (Suborder Mysticeti) [PDF]

open access: yesMolecular Biology and Evolution, 2009
Baleen whales are the largest animals that have ever lived. To develop an improved estimation of substitution rate for nuclear and mitochondrial DNA for this taxon, we implemented a relaxed-clock phylogenetic approach using three fossil calibration dates: the divergence between odontocetes and mysticetes approximately 34 million years ago (Ma), between

Catalogue of marine mammals of the Mammalogical collection of the Museo de La Plata, Argentina

open access: yesRevista del Museo de La Plata, 2016
This catalogue lists the materials of marine mammals housed in the Mammalogical collection of Museo de La Plata. This contribution is an update of the unpublished catalogue made by R. Bastida, J.B. Desojo, and L.H. Soibelzon in 1997. It includes all the

Structure of the cerebral cortex of the humpback whale,Megaptera novaeangliae (Cetacea, Mysticeti, Balaenopteridae) [PDF]

open access: yesThe Anatomical Record Part A: Discoveries in Molecular, Cellular, and Evolutionary Biology, 2006
AbstractCetaceans diverged from terrestrial mammals between 50 and 60 million years ago and acquired, during their adaptation to a fully aquatic milieu, many derived features, including echolocation (in odontocetes), remarkable auditory and communicative abilities, as well as a complex social organization. Whereas brain structure has been documented in

Enamel Microstructure in Eocene Cetaceans from Antarctica (Archaeoceti and Mysticeti)

open access: yesJournal of Mammalian Evolution, 2019
Modern baleen whales have no adult teeth, whereas dolphins and porpoises have a homodont and polydont dentition, with simplified enamel microstructure. However, archaic cetaceans (archaeocetes and early mysticetes and odontocetes) had a complex and ornamented dentition, with complex enamel microstructure as in terrestrial mammals.

A new species of Middle Miocene baleen whale from the Nupinai Group, Hikatagawa Formation of Hokkaido, Japan [PDF]

open access: yesPeerJ, 2018
A fossil whale from the Hikatagawa Formation (Middle Miocene, 15.2–11.5 Ma) of Hokkaido, Japan is described as a new genus and species Taikicetus inouei and its phylogenetic position is examined.
