Tere Tohorā, Karanga Tāngata: Weaving Māori Knowledge With Conventional Science to Characterise a Biodiversity Hotspot for Marine Megafauna in an Area Facing Multiple Anthropogenic Impacts Open
Marine megafauna are important components of marine ecosystems and are of major significance to Indigenous communities, including Māori. Despite being recognised as a biodiversity hotspot for megafauna, most locations in Aotearoa New Zeala…

Spatial Modelling Approaches for Estimating Richness of Benthic Invertebrates Throughout New Zealand Waters Open
Aim Understanding the distribution of marine biodiversity is critical for evidence‐based identification of areas for protection and restoration. Taxonomic richness is a key, intuitive component of biodiversity and is often used to guide ma…

Solitary humpback whales manufacture bubble-nets as tools to increase prey intake Open
Several animal species use tools for foraging; however, very few manufacture and/or modify those tools. Humpback whales, which manufacture bubble-net tools while foraging, are among these rare species. Using animal-borne tag and unoccupied…

Using passive acoustic monitoring to assess the overlap between endemic endangered Hector's dolphin (<span><i>Cephalorhynchus hectori hectori</i></span>) and mussel farms in the Banks Peninsula Marine Mammal Sanctuary, New Zealand Open
Aquaculture has maintained a sustained growth trend over the last 50 years, worldwide and in Aotearoa New Zealand. This industry is known to have environmental consequences, such as impacts on benthos, water column and higher trophic level…

Modelling spatial distributions of biogenic habitat‐forming taxa to inform marine spatial planning Open
Biogenic habitats are foundational habitats for species assemblages and drive a range of ecosystem functions. The Hauraki Gulf/Tiikapa Moana is the most intensively used coastal area in Aotearoa/New Zealand, and decades of commercial fishi…

Quantifying the age structure of free‐ranging delphinid populations: Testing the accuracy of Unoccupied Aerial System photogrammetry Open
Understanding the population health status of long‐lived and slow‐reproducing species is critical for their management. However, it can take decades with traditional monitoring techniques to detect population‐level changes in demographic p…

Population comparison of right whale body condition reveals poor state of the North Atlantic right whale Open
The North Atlantic right whale Eubalaena glacialis (NARW), currently numbering <410 individuals, is on a trajectory to extinction. Although direct mortality from ship strikes and fishing gear entanglements remain the major threats to the p…

Variation in outer blubber lipid concentrations does not reflect morphological body condition in humpback whales Open
An animal's body condition provides valuable information for ecophysiological studies, and is an important measure of fitness in population monitoring and conservation. While both the external body shape of an animal, as well as its intern…

Underwater noise from pile-driving and its impact on Hector's dolphins in Lyttelton Harbour, New Zealand Open
Noise levels were measured in Lyttelton Harbour in order to study pile-driving noise produced during wharf reconstruction. Sound recordings were made throughout the harbour, using several moored and mobile recording systems. In addition, a…

Inexpensive Aerial Photogrammetry for Studies of Whales and Large Marine Animals Open
We describe a simple system enabling accurate measurement of swimming marine mammals and other large vertebrates from low-altitude single-frame photogrammetry via inexpensive modifications to a “prosumer” unmanned aerial vehicle (UAV) equi…
