Risk Assessment of Whale Entanglement and Vessel Strike Injuries From Case Narratives and Classification Trees

open access: yesFrontiers in Marine Science, 2022
Entanglements and vessel strikes impact large whales worldwide. Post-event health status is often unknown because whales are seen once or over short spans that conceal long-term health declines.

Whales and Whaling: a Dance of Death [PDF]

open access: yesOryx, 1975
The whaling industry and its raw material, the whale stocks of the world, continue their grim Totentanz towards their mutual extinction. The most significant event of the 27th meeting of the International Whaling Commission in London in June, and one of the least publicised, was the Soviet announcement that next season they would have only two instead ...

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Drone Up! Quantifying Whale Behavior From a New Perspective Improves Observational Capacity

open access: yesFrontiers in Marine Science, 2018
From our traditional boat-based horizontal perspective, marine megafauna behavioral observations are typically limited to animal surfacings. Achieving an aerial perspective has been restricted to brief helicopter or airplane based observations that are ...

Whale of a tale [PDF]

open access: yesAnnals of the Rheumatic Diseases, 2005
Spondyloarthropathy is the term applied to a form of arthritis with sentinel alteration of the spine, in the form of syndesmophytes and zygapophyseal joint erosions.1–3 Although a single zygapophyseal joint can be damaged by pyogenic or rarely by a granulomatous infection, the only known cause of multiple zygapophyseal joint erosions is ...

Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint

open access: yesThe Anatomical Record, EarlyView.
Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),

Prediction of Large Whale Distributions: A Comparison of Presence–Absence and Presence-Only Modeling Techniques

open access: yesFrontiers in Marine Science, 2018
Species distribution models that predict species occurrence or density by quantifying relationships with environmental variables are used for a variety of scientific investigations and management applications. For endangered species, such as large whales,

When and Where Did They Strand? The Spatio-Temporal Hotspot Patterns of Cetacean Stranding Events in Indonesia

open access: yesOceans, 2022
Analyses of the spatial and temporal patterns of 26 years of stranding events (1995–2011 and 2012–2021, n = 568) in Indonesia were conducted to improve the country’s stranding response.

Genome-culture coevolution promotes rapid divergence of killer whale ecotypes

open access: yesNature Communications, 2016
Analysing population genomic data from killer whale ecotypes, which we estimate have globally radiated within less than 250,000 years, we show that genetic structuring including the segregation of potentially functional alleles is associated with ...

Morphology and function of pinniped necks: The long and short of it

open access: yesThe Anatomical Record, EarlyView.
Abstract Terrestrial vertebrates from at least 30 distinct lineages in both extinct and extant clades have returned to aquatic environments. With these transitions came numerous morphological adaptations to accommodate life in water. Relatively little attention has been paid to the cervical region when tracking this transition.
