Epigenetic Age Estimation for Hawaiian False Killer Whales (Pseudorca crassidens) in the Absence of ‘Known-Age’ Individuals

Epigenetic aging models hold great promise for enhancing many aspects of wildlife research and management. However, their utility is limited

The Shyest Blackfish: The Global Phylogeography of the Pygmy Killer Whale (Feresa attenuata) Suggests Considerable Population Structure and an Unrecognized Taxon

Pygmy killer whales (Feresa attenuata) are a poorly studied, globally-distributed species found in pelagic waters and around oceanic islands. They

Acoustic Behaviour of Endangered Hawaiian False Killer Whales

Understanding the acoustic communication of the endangered main Hawaiian Islands insular population of false killer whales (Pseudorca crassidens) is essential

How Robust is Eschrichtius robustus? A Novel Photographic Index of Body Condition From Boat-Based Photographs of Gray Whales

Although the eastern North Pacific gray whale (Eschrichtius robustus) population has recovered from population declines associated with whaling, they are

Daily Energetic Expenditure and Energy Consumption of Short-Finned Pilot Whales

Diving is one of the most important behaviors undertaken by marine mammals. Pilot whales (Globicephala spp.) are oceanic dolphins that

Deriving Probabilistic Age Estimates Using Common Photo-Identification Catalog Information: An Application to Endangered Hawaiian False Killer Whales (Pseudorca crassidens)

Age is important for studying population dynamics, but it is difficult to obtain reasonably accurate age estimates and associated uncertainty

A Comparison of Diving Behavior of Goose-Beaked and Dense-Beaked Whales From Tagging Studies in Multiple Ocean Basins

Studies of cetacean diving behavior in multiple locations in different ocean basins allow for an assessment of variability within and

Accounting for Sampling Bias Reveals a Decline in Abundance of Endangered False Killer Whales in the Main Hawaiian Islands

We estimated abundance of the endangered main Hawaiian Islands (MHI) insular population of false killer whales Pseudorca crassidens from 1999-2022 using a

Variation in Social Structure Among Multiple Stocks of Island-Associated Common Bottlenose Dolphins (Tursiops truncatus) in Hawaiian Waters

ABSTRACT The drivers of animal social structures remain poorly understood, particularly in species such as cetaceans that are wide-ranging and

Using Spatial Capture-Recapture Methods to Estimate Long-Term Spatiotemporal Variation of a Wide-Ranging Marine Species

Determining population status to inform mitigation of anthropogenic threats requires statistical approaches that investigate spatial and temporal variation. In the
