Phylogeny and adaptive evolution of the brain-development gene microcephalin (MCPH1) in cetaceans [PDF]

open access: yesBMC Evolutionary Biology, 2011
Background Representatives of Cetacea have the greatest absolute brain size among animals, and the largest relative brain size aside from humans. Despite this, genes implicated in the evolution of large brain size in primates have yet to be surveyed in ...

Back to Water: Signature of Adaptive Evolution in Cetacean Mitochondrial tRNAs. [PDF]

open access: yesPLoS ONE, 2016
The mitochondrion is the power plant of the eukaryotic cell, and tRNAs are the fundamental components of its translational machinery. In the present paper, the evolution of mitochondrial tRNAs was investigated in the Cetacea, a clade of Cetartiodactyla ...

Comparative chromosome studies in Cetacea [PDF]

open access: goldHereditas, 2009
The karyology was studied in 9 species of cetaceans, viz. in 5 odontocetes and 4 mysticetes. Chromosome measurements and idiograms of 8 species are presented. Comparisons were made between the karyotypes of the different species on the basis of conventional staining methods as well as by autoradiography and by Q-, G-, and C-banding techniques.

Wild Cetacea Identification using Image Metadata

open access: greenJournal of Computer Science and Technology, 2017
Identification of individuals in marine species, especially in Cetacea, is a critical task in several biological and ecological endeavours. Most of the times this is performed through human-assisted matching within a set of pictures taken in different ...

A new diminutive fossil ziphiid from the deep-sea floor off northern Chile and some remarks on the body size evolution and palaeobiogeography of the beaked whales [PDF]

open access: yesActa Palaeontologica Polonica, 2023
The evolutionary history of the beaked whales (Ziphiidae), odontocetes nowadays adapted to deep diving, is well known thanks to a significant fossil record mainly from the deep ocean floors.

Bycatch of marine mammals in the Northwest Atlantic during commercial fishery (based on literature materials and observations by the Polar branch of VNIRO in 2013–2020)

open access: yesVestnik MGTU, 2022
This paper describes one of the most acute problem for both environmental companies and fisheries – bycatch of marine mammals caused by bioresource exploitation in the Northwest Atlantic (NWA).
