Variability in individual rates of aggression in wild gray seals : fine-scale analysis reveals importance of social and spatial stability
(2015-10) - Journal article
Aggressive interactions are costly for individuals in time, energy, or physical damage, and in polygynous mating systems, there is high variability in the rates and intensity of aggression across individuals and within ...
A review of unmanned vehicles for the detection and monitoring of marine fauna
(2019-03) - Journal item
Recent technology developments have turned present-day unmanned systems into realistic alternatives to traditional marine animal survey methods. Benefits include longer survey durations, improved mission safety, mission ...
Whistle characteristics and daytime dive behavior in pantropical spotted dolphins (Stenella attenuata) in Hawai‘i measured using digital acoustic recording tags (DTAGs)
(2016-07-19) - Journal article
This study characterizes daytime acoustic and dive behavior of pantropical spotted dolphins (Stenella attenuata) in Hawai‘i using 14.58 h of data collected from five deployments of digital acoustic recording tags (DTAG3) ...
Assessing the design and power of capture-recapture studies to estimate population growth rate and abundance of the endangered Oceania humpback whale population
(2015) - Journal article
Capture-recapture studies offer a powerful tool to assess abundance, survival and population rate of change (λ). A previous capture-recapture study, based on DNA profiles, estimated that the IUCN-listed Endangered Oceania ...
Not just fat : investigating the proteome of cetacean blubber tissue
(2018) - Journal article
Mammalian adipose tissue is increasingly being recognized as an endocrine organ involved in the regulation of a number of metabolic processes and pathways. It responds to signals from different hormone systems and the ...
Modeling tissue and blood gas kinetics in coastal and offshore common bottlenose dolphins, Tursiops truncatus
(2018-07-17) - Journal article
Bottlenose dolphins (Tursiops truncatus) are highly versatile breath-holding predators that have adapted to a wide range of foraging niches from rivers and coastal ecosystems to deep-water oceanic habitats. Considerable ...
The stuff and nonsense of open data in government

Following a foraging fish-finder : Diel habitat use of Blainville's beaked whales revealed by echolocation
(2011-12-07) - Journal article
Simultaneous high resolution sampling of predator behavior and habitat characteristics is often difficult to achieve despite its importance in understanding the foraging decisions and habitat use of predators. Here we tap ...
Culturally transmitted song exchange between humpback whales (Megaptera novaeangliae) in the southeast Atlantic and southwest Indian Ocean basins
(2018-11) - Journal article
In migratory marine species, investigating population connectivity and structure can be challenging given barriers to dispersal are less evident and multiple factors may influence individual movement patterns. Male humpback ...
Killer whales (Orcinus orca) in Iceland show weak genetic structure among diverse isotopic signatures and observed movement patterns
(2018-11-14) - Journal article
Local adaption through ecological niche specialization can lead to genetic structure between and within populations. In the Northeast Pacific, killer whales (Orcinus orca) of the same population have uniform specialized ...
