Range-dependent flexibility in the acoustic field of view of echolocating porpoises (Phocoena phocoena)

eLife (2015)

Toothed whales use sonar to detect, locate, and track prey. They adjust emitted sound intensity, auditory sensitivity and click rate to target range, and terminate prey pursuits with high-repetition-rate, low-intensity…


Revision of the taxonomy of finless porpoises (genus Neophocaena): the existence of two species

Jefferson, Thomas A.; Wang, John Y.
Journal of Marine Animals and Their Ecology (2011)

Due to extensive morphological variation and inadequately-sampled or poorly-designed studies, the taxonomy of the finless porpoises (genus Neophocaena) has been controversial for some time. An uneasy stability with the arrangement…


Phylogeography, intraspecific structure and sex-biased dispersal of Dall’s porpoise, Phocoenoides dalli , revealed by mitochondrial and microsatellite DNA analyses

Escorza-Treviño, S.; Dizon, A. E.
Molecular Ecology (2000)

Mitochondrial DNA (mtDNA) control-region sequences and microsatellite loci length polymorphisms were used to estimate phylogeographical patterns (historical patterns underlying contemporary distribution), intraspecific population structure and gender-biased dispersal of Phocoenoides dalli…


The phylogenetic relationships and biogeography of true porpoises (Mammalia: Phocoenidae) based on morphological data

Fajardo-Mellor, Liliana; Berta, Annalisa; Brownell, Robert L.; Boy, Claudia C.; Goodall, R. Natalie P.
Marine Mammal Sci (2006)

Prior studies of phylogenetic relationships among phocoenids based on morphology and molecular sequence data conflict and yield unresolved relationships among species. This study evaluates a comprehensive set of cranial, postcranial,…
