Deleterious Mutations in the Mitogenomes of Cetacean Populations [PDF]

Biology
Cetaceans are artiodactyls adapted to live in the marine environment, and this group includes whales, dolphins, and porpoises. Although mitochondrial nucleotide diversity has been reported separately for many cetacean groups, the proportion of ...

Up in the air: drone images reveal underestimation of entanglement rates in large rorqual whales

Endangered Species Research, 2021
Entanglement in fishing gear is a significant threat to many cetaceans. For the 2 largest species, the blue whale Balaenoptera musculus and the fin whale B. physalus, reports of entangled individuals are rare, leading to the assumption that entanglements

Tattoo Skin Disease in Cetacea: A Review, with New Cases for the Northeast Pacific

Animals, 2022
Tattoo skin disease (TSD) is a poxviral dermatopathy diagnosed in cetaceans. We review the literature on TSD aetiology, clinical characteristics, pathology and epidemiology and evaluate immune responses against the virus.

A First Study on Distribution Characteristics of Common Dolphin in Korean Waters: A Study Using Data Collected during the Past 20 Years

Journal of Marine Science and Engineering, 2023
The common dolphin (Delphinus delphis) is the second-most bycaught species in Korean waters. To provide key information about their habitat boundaries and hotspots for spatial conservation and management, the spatial use of this species was examined ...

Too Close for Comfort? Isotopic Niche Segregation in New Zealand’s Odontocetes

Biology, 2022
Species occurring in sympatry and relying on similar and limited resources may partition resource use to avoid overlap and interspecific competition.

Cetacean conservation planning in a global diversity hotspot: dealing with uncertainty and data deficiencies

Ecosphere, 2021
Many cetacean species are at risk from anthropogenic disturbances including climate change, pollution, and habitat degradation. Identifying cetacean hotspots for conservation management is therefore required.

Sex-specific patterns in abundance, temporary emigration and survival of Indo-Pacific bottlenose dolphins (Tursiops aduncus) in coastal and estuarine waters

Frontiers in Marine Science, 2016
Inherent difficulties in determining the sex of free-ranging sexually monomorphic species often prevents a sex-specific focus on estimating abundance, movement patterns and survival rates.
