Four sightings of Ziphiidae (Cetacea, Odontoceti) in the Central Tyrrhenian Sea / Quattro avvistamenti di Ziphiidae (Cetacea, Odontoceti) nel Mar Tirreno Centrale

Hystrix, the Italian Journal of Mammalogy, 1992
<strong>Abstract</strong> The sighting of four couples of Ziphiidae in the Central Tyrrhenian Sea has been reported. Some considerations about geographic distribution of such cetaceans in the Italian seas are set out below.

Mesoplodon densirostris (Cetacea, Ziphiidae), primeiro registro para o Atlántico Sul Ocidental [PDF]

Brazilian Journal of Oceanography, 1980
A female Blainville's beaked whale, Mesopiodon densirostris, 4.4m long was found stranded at 42km, South of Cassino, Rio Grande do Sul, Brazil. The triangular shape and dimensions of the pair of unerupted teeth (60 x 45 x 11 mm) in the lower jaw ...

Whale fall chemosymbiotic communities in a southwest Australian submarine canyon fill a distributional gap [PDF]

Heliyon
A whale fall community of chemosymbiotic invertebrates living on cetacean bones has been identified off southwestern Australia during a Remotely Operated Vehicle (ROV) survey at bathyal depths within the Bremer Marine Park, which is part of important ...

Declining abundance of beaked whales (family Ziphiidae) in the California Current large marine ecosystem.

PLoS ONE, 2013
Beaked whales are among the most diverse yet least understood groups of marine mammals. A diverse set of mostly anthropogenic threats necessitates improvement in our ability to assess population status for this cryptic group.

Navigating Cetacean Mitochondrial Genome Data: Identifying Coverage and Deficiencies in Public Repositories. [PDF]

Mol Ecol Resour
ABSTRACT Genetic reference databases underpin a wide range of molecular approaches used to study cetacean biodiversity, including environmental DNA (eDNA), yet their reliability depends critically on data completeness, taxonomic accuracy, and metadata quality.

Ocean-wide genomic variation in Gray's beaked whales, Mesoplodon grayi [PDF]

Royal Society Open Science, 2021
The deep oceans of the Southern Hemisphere are home to several elusive and poorly studied marine megafauna. In the absence of robust observational data for these species, genetic data can aid inferences on population connectivity, demography and ecology.

Drivers of Viral Diversity and Sharing in Marine Mammals. [PDF]

Mol Ecol
ABSTRACT Knowledge of viral infection in marine mammals, a group severely threatened by human activity, is largely limited to the pathology and epidemiology of few endemic viruses. The recent emergence in marine mammals of high‐consequence viruses, such as H5N1 avian influenza and rabies, underscores the importance of understanding the ecology of viral

Post-Release Survival and Behavioral Recovery of a Rehabilitated Short-Finned Pilot Whale (<i>Globicephala macrorhynchus</i>) in the South China Sea Revealed Through Satellite Tracking. [PDF]

Ecol Evol
This study presents the first empirical evidence of successful rehabilitation and post‐release monitoring of a short‐finned pilot whale in the South China Sea—a region where such data are critically lacking despite frequent stranding events. Using satellite telemetry and a dedicated resighting expedition, we documented the 52‐day movement, diving ...

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]

Acta 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.

How large should whales be? [PDF]

, 2013
The evolution and distribution of species body sizes for terrestrial mammals is well-explained by a macroevolutionary tradeoff between short-term selective advantages and long-term extinction risks from increased species body size, unfolding above the 2g
