Endangered Species Research (2019)

In 2017 an emergency field effort was undertaken in an attempt to prevent the extinction of the world’s most endangered marine mammal, the vaquita (Phocoena sinus). The rescue effort involved…


Cytokine expression and lymphocyte proliferative capacity in diseased harbor porpoises (Phocoena phocoena) – Biomarkers for health assessment in wildlife cetaceans

Lehnert, Kristina; Siebert, Ursula; Reißmann, Kristina; Bruhn, Regina; McLachlan, Michael S.; Müller, Gundi; van Elk, Cornelis E.; Ciurkiewicz, Malgorzata; Baumgärtner, Wolfgang; Beineke, Andreas
Environmental Pollution (2019)

Harbor porpoises (Phocoena phocoena) in the North and Baltic Seas are exposed to anthropogenic influences including acoustic stress and environmental contaminants. In order to evaluate immune responses in healthy and…


Porpoises the world over: Diversity in behavior and ecology

Teilmann, Jonas; Sveegaard, Signe
Ethology and Behavioral Ecology of Odontocetes (2019)

Unlike the large number of species of true dolphins, there are only seven porpoise or phocoenid species, inhabiting different habitats and climate zones. They range from ice-covered water in the…


Histological variation in blubber morphology of the endangered East Asian finless porpoise (Neophocaena asiaeorientalis sunameri) with ontogeny and reproductive states

Ji, Junhua; Nabi, Ghulam; Zeng, Xianyuan; Hao, Yujiang; Wang, Ding
Zoological Studies (2019)

The highly lipid-rich blubber in the hypodermis is a specialized structure that functions in thermoregulation, energy storage, buoyancy control, locomotion, and streamlining the body shape in marine mammals. The key…


Physical modeling and validation of porpoises’ directional emission via hybrid metamaterials

Dong, Erqian; Zhang, Yu; Song, Zhongchang; Zhang, Tianye; Cai, Chen; Fang, Nicholas X.
National Science Review (2019)

In wave physics and engineering, directional emission sets a fundamental limitation on conventional simple sources as their sizes should be sufficiently larger than their wavelength. Artificial metamaterial and animal biosonar…


Genetic homogeneity in the face of morphological heterogeneity in the harbor porpoise from the Black Sea and adjacent waters (Phocoena phocoena relicta)

Ben Chehida, Yacine; Thumloup, Julie; Vishnyakova, Karina; Gol’din, Pavel; Fontaine, Michael C.
Heredity (2019)

Absence of genetic differentiation is usually taken as an evidence of panmixia, but can also reflect other situations, including even nearly complete demographic independence among large-sized populations. Deciphering which situation…
