Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin

The Anatomical Record, EarlyView.
Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.

Histochemical indications for a chemically complex signal produced by the cervical gill slit gland of the pygmy sperm whale (Kogia breviceps)

The Anatomical Record, EarlyView.
Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland

Leveraging Synteny to Generate Reference Genomes for Conservation: Assembling the Genomes of Hector's and Māui Dolphins

Molecular Ecology Resources, EarlyView.
ABSTRACT Escalating concern regarding the impacts of reduced genetic diversity on the conservation of endangered species has spurred efforts to obtain chromosome‐level genomes through consortia such as the Vertebrate Genomes Project. However, assembling reference genomes for many threatened species remains challenging due to difficulties obtaining ...

Observation Bias in Metabarcoding

Molecular Ecology Resources, EarlyView.
ABSTRACT DNA metabarcoding is subject to observation bias associated with PCR and sequencing, which can result in observed read proportions differing from actual species proportions in the DNA extract. Here, we amplify and sequence a mock community of known composition containing marine fishes and cetaceans using four different primer sets and a ...

Prioritizing future evidence needs for marine and freshwater mammal conservation action

Animal Conservation, EarlyView.
To improve conservation practice, decisions should be informed by the available evidence on the effectiveness of conservation actions. Here, we review the comprehensiveness of this evidence base for marine and freshwater mammals. We assess the taxonomic and geographic coverage of the evidence base, identify biases and suggest priorities for future ...

Close encounters of the friendly kind: pacific between‐group interactions in primates

Biological Reviews, EarlyView.
ABSTRACT While intergroup conflict features prominently in the behavioural ecology literature, its antonym, intergroup peace, has been a rather neglected phenomenon until recently. Neighbourly relations and affiliative interactions are far from uncommon.

The departure of sperm whales (Physeter macrocephalus) in response to the declining jumbo squid (Dosidicus gigas) population in the central portion of the Gulf of California [PDF]

PeerJ
As sperm whales are important predators that control energy flux in the oceans, changes in their population can be used as a sentinel to measure of ecosystem health.

Spatial conservation priorities for marine megafaunal predators: Multi‐taxon versus taxon‐specific approaches

Conservation Science and Practice, EarlyView.
Conservation for marine megafaunal predators needs to improve as they are key for ecosystem functioning. We show that different marine predator taxonomic groups have heterogeneous distributions resulting in different spatial conservation priority areas. Current Mediterranean MPAs are failing to sufficiently cover their distributions.

Leviathans and Liberation: Did Whaling Contribute to the Decline of Slavery?

International Social Science Journal, EarlyView.
ABSTRACT We test the hypothesis slavery started declining in the United States not due to fossil fuel‐driven industrialization but the exploitation of the bioenergy reserves of the world's largest animals. We predict the population in slavery in US states from 1790 to 1840 as a function of the recorded whaling harvest.

Crowdsourcing modern and historical data identifies sperm whale (Physeter macrocephalus) habitat offshore of south-western Australia

Frontiers in Marine Science, 2016
The distribution and use of pelagic habitat by sperm whales (Physeter macrocephalus) is poorly understood in the south-eastern Indian Ocean off Western Australia.
