The Anatomical Record (2013)
Evolution of endocranial anatomy in cetaceans is important from the perspective of echolocation ability, intelligence, social structure, and alternate pathways for circulation to the brain. Apart from the importance of…
Ultrastructure of enamel and dentine in extant dolphins (Cetacea: Delphinoidea and Inioidea)
Loch, Carolina; Duncan, Warwick; Simões-Lopes, Paulo C.; Kieser, Jules A.; Fordyce, R. Ewan
Zoomorphology (2012)
Longitudinal and cross sections of teeth from 17 species of the Recent dolphins (Delphinoidea and Inioidea) were examined under scanning electron microscope to study the arrangement and ultrastructure of dental…
Comparative morphology of porpoise (Cetacea: Phocoenidae) pterygoid sinuses: Phylogenetic and functional implications
Racicot, Rachel A.; Berta, Annalisa
Journal of Morphology (2012)
High-resolution X-ray computed tomographic scans were used to examine pterygoid sinus morphology within extant porpoise species and one delphinid (Tursiops truncatus), in order to consider: 1) intraspecific and interspecific variation…
Histopathological aspects and etiology of pneumonias in stranded marine mammals from Lima, Peru
Gonzales-Viera, Omar; Chavera, Alfonso; Yaipén-Llanos, Carlos; Perales-Camacho, Rosa
Brazilian Journal of Veterinary Pathology (2011)
This study presents the histopathologic features of pneumonia in stranded marine mammals on the coast of Lima, Peru during the period of May 2003 to December 2008. Lung samples of…
Isotopic assessment of prey and habitat preferences of a cetacean community in the southwestern South Atlantic Ocean
Riccialdelli, L.; Newsome, S. D.; Fogel, M. L.; Goodall, R. N. P.
Marine Ecology Progress Series (2010)
We used stable carbon (δ13 C) and nitrogen (δ15 N) isotope analysis to investigate the trophic ecology of 8 small cetacean species of the southwestern South Atlantic Ocean: 6 delphinids…
Small cetacean captures in Peruvian artisanal fisheries: High despite protective legislation
Mangel, Jeffrey C.; Alfaro-Shigueto, Joanna; Van Waerebeek, Koen; Cáceres, Celia; Bearhop, Stuart; Witt, Matthew J.; Godley, Brendan J.
Biological Conservation (2010)
We detail the first direct, at sea monitoring of small cetacean interactions with Peruvian artisanal drift gillnet and longline fisheries. A total of 253 small cetaceans were captured during 66…
Molecular identification of small cetacean samples from Peruvian fish markets
Tzika, Athanasia C.; D’Amico, Eva; Alfaro-Shigueto, Joanna; Mangel, Jeffrey C.; Van Waerebeek, Koen; Milinkovitch, Michel C.
Conservation Genetics (2010)
In the last 60 years, incidental entanglement in fishing gears (so called by-catch) became the main cause of mortality worldwide for small cetaceans and is pushing several populations and species…
Diversity and summer distribution of cetaceans in inlet waters of northern Aisén, Chile
Zamorano-Abramson, José; Gibbons, Jorge; Capella, Juan
Anales del Instituto de la Patagonia (2010)
(...) In this paper we present results on diversity, local distribution and group composition of cetacean species along inshore waters of the fjord Puyuhuapi and Channels Jacaf and Moraleda (between…
Interspecific variation of ontogeny and skull shape among porpoises (Phocoenidae)
Galatius, Anders; Berta, Annalisa; Frandsen, Marie Schou; Goodall, R. Natalie P.
Journal of Morphology (2010)
All extant members of Phocoenidae (porpoises) have been characterized as pedomorphic based on skeletal characters. To investigate the ontogenetic background for pedomorphosis and assess interspecific differences in ontogeny among phocoenids,…
Paedomorphic ossification in porpoises with an emphasis on the Vaquita (Phocoena sinus)
Mellor, Liliana; Cooper, Lisa Noelle; Torre, Jorge; Brownell, Robert L.
Aquatic Mammals (2009)
Heterochrony, the change in timing of developmental processes, is thought to be a key process shaping the numerous limb morphologies of tetrapods. Through a delayed offset in digit development, all…
