Tending the sick: Observations of epimeletic behavior in humpback whales towards conspecifics during entanglement events Open
Anthropogenic impacts on marine systems are increasing in frequency, geographic range and severity. While changes in climate will likely lead to the greatest impacts at the system-level, for marine megafauna, entanglement in marine debris …

Movement and sound production in yearling humpback whales: age-class comparisons Open
The juvenile period is an important stage of growth and development across animals, often consisting of graded stages of physical and social development. For cetaceans, locomotor and social development are key to survival after weaning; in…

Signal partitioning between native and introduced forest birds of Hawai‘i Island Open
Birds use sound for conspecific communication. According to the acoustic niche hypothesis, they avoid signal competition with other species by partitioning sound in frequency and time. Others have observed introduced species changing the v…

Imitation of Computer-Generated Sounds by Wild Atlantic Spotted Dolphins (Stenella frontalis) Open
Since 1985 a community of wild Atlantic spotted dolphin (Stenella frontalis) have been observed underwater in the Bahamas. A human-worn, acoustic underwater two-way communication interface was developed and deployed from 2013-2016. Dolphin…

Bellwethers of change: population modelling of North Pacific humpback whales from 2002 through 2021 reveals shift from recovery to climate response Open
For the 40 years after the end of commercial whaling in 1976, humpback whale populations in the North Pacific Ocean exhibited a prolonged period of recovery. Using mark–recapture methods on the largest individual photo-identification datas…

Diel spatio-temporal patterns of humpback whale singing on a high-density breeding ground Open
Humpback whale song chorusing dominates the marine soundscape in Hawai‘i during winter months, yet little is known about spatio-temporal habitat use patterns of singers. We analysed passive acoustic monitoring data from five sites off Maui…

A collaborative and near-comprehensive North Pacific humpback whale photo-ID dataset Open
We present an ocean-basin-scale dataset that includes tail fluke photographic identification (photo-ID) and encounter data for most living individual humpback whales ( Megaptera novaeangliae ) in the North Pacific Ocean. The dataset was bu…

(Almost) all the humpback whales of the North Pacific: A collaborative and comprehensive photo-ID dataset Open
We present an ocean-basin-scale dataset that includes tail fluke photographic identification (photo-ID) and encounter data for the majority of living individual humpback whales ( Megaptera novaeangliae ) in the North Pacific Ocean. The dat…

Aerial survey perspectives on humpback whale resiliency in Maui Nui, Hawai’i, in the face of an unprecedented North Pacific marine warming event Open
After decades of population growth, the central stock of the North Pacific population of humpback whales, known as the Hawai’i Distinct Population Segment (HDPS), was delisted from its endangered status in 2016. At that time, however, an u…

Comparing the social signaling behavior of humpback whales in three group types on the Hawaiian breeding grounds using acoustic tags Open
Humpback whales ( Megaptera novaeangliae ) are exceptionally vocal among baleen whale species. While extensive research has been conducted on humpback whale songs, gaps remain in our understanding of other forms of communication, particula…

Male Humpback Whale Chorusing in Hawai‘i and Its Relationship With Whale Abundance and Density Open
Passive acoustic monitoring (PAM) with autonomous bottom-moored recorders is widely used to study cetacean occurrence, distribution and behaviors, as it is less affected by factors that limit other observation methods (e.g., vessel, land a…

Social Behaviour of Humpback Whales (Megaptera novaeangliae) in Hervey Bay, Eastern Australia, a Preferential Female Stopover During the Southern Migration Open
Agonistic competitive social behaviour in humpback whales [ Megaptera novaeangliae (Borowski, 1781)] has been extensively studied and reported in previous research. However, non-agonistic social behaviour in humpback whale pods has not bee…

The effect of isolation, fragmentation, and population bottlenecks on song structure of a Hawaiian honeycreeper Open
Little is known about how important social behaviors such as song vary within and among populations for any of the endemic Hawaiian honeycreepers. Habitat loss and non‐native diseases (e.g., avian malaria) have resulted in isolation and fr…

Exodus! Large-scale displacement and social adjustments of resident Atlantic spotted dolphins (Stenella frontalis) in the Bahamas Open
Over the last 20 years, significant habitat shifts have been documented in some populations of cetaceans. On Little Bahama Bank (LBB) there are sympatric communities of resident Atlantic spotted dolphins (Stenella frontalis) and bot…
