Animal body size and growth patterns play important roles in shaping the life history of species. Baleen whales include largest animals on planet, with somatic costs expected to be substantial. We used unmanned aerial vehicle photogrammetry long-term individual sighting histories from photo identification (1991-2019) estimate cost for southern right (SRWs) Eubalaena australis . A Richards length-at-age model was developed, based 161 calves, 20 yearlings, 1 juvenile 23 adults, ranging age...
North Atlantic right whales (NARW), Eubalaena glacialis , were nearly exterminated by historical whaling. Their abundance slowly increased up until 2010, to a maximum of fewer than 500 whales, and since then they have been in decline. We assessed the extent which relatively slow increase demonstrated NARW was intrinsic, how much could be due anthropogenic impacts. In order do so, we first compared calf counts three populations Southern (SRW), E. australis with that NARW, over period...
Abstract Unmanned aerial vehicles (UAVs) are increasingly used for wildlife research and monitoring, but little information exists on their potential effect marine mammals. We assessed the effects of a UAV behavior southern right whales ( Eubalaena australis ) in Australia. Focal follows ten whale mother‐calf pairs were conducted using theodolite. Control data recorded 30 min, then DJI Inspire 1 Pro was flown above 10 min at 5 m altitude. Potential changes to horizontal (swim speed turning...
Abstract Photo identification is an important tool in the conservation management of endangered species, and recent developments artificial intelligence are revolutionizing existing workflows to identify individual animals. In 2015, National Oceanic Atmospheric Administration hosted a Kaggle data science competition automate North Atlantic right whales ( Eubalaena glacialis ). The winning algorithms developed by Deepsense.ai were able individuals with 87% accuracy using series convolutional...
In Australian waters, southern right whales Eubalaena australis form 2 genetically distinct populations that have shown contrasting patterns of recovery since whaling ceased: a western population in South Australia and Western an eastern southeastern (Tasmania, Victoria New Wales). Here, we provide abundance estimate derived from breeding female superpopulation mark-recapture model for the whale population. The comprises 268 individuals (68 females) has increased at rate 4.7% per annum...
Abstract Seasonal trends in the distribution and relative abundance of southern right whales (SRWs) Eubalaena australis , were assessed Australia's largest calving aggregation ground at Head Great Australian Bight, Commonwealth Marine Reserve, South Australia. Annual cliff‐based surveys undertaken between June October from 1992 to 2016. SRWs primarily distributed a 15 km by 2 area within 10 m depth contour (with 95% whale sightings made area). The Bight varied an individual season but was...
Within New Zealand and eastern Australia, over 58,000 southern right whales were harvested by commercial whalers between 1790 1980, with approximately 19,000 from south-eastern Australia. Local extirpation is believed to have led a loss of cultural memory calving areas, contributing the limited recovery Australian population. While number observed using coastline increasing, there has been no change three decades in annual abundance cow-calf pairs at Logans Beach Warrnambool, Victoria, only...
Abstract Demographic parameters were estimated for southern right whales (SRWs), Eubalaena australis , using photo‐identification (photo‐ID) and count data collected during annual cliff‐based surveys at the Head of Great Australian Bight (HoB), South Australia between 1991 2016. Photo‐ID contributed from aerial south‐western population in (1993–2016). The HoB photo‐ID database included 1,186 non‐calf individuals, with 459 reproductive females. is an open represents a relative proportion...
Abstract Southern right whales (SRW), Eubalaena australis , have reoccupied historically important winter habitat ranges (calving grounds) in recent years along the southern Australian coast. Here we present findings of increased abundance SRW at Fowlers Bay, South Australia, a previous shore‐based whaling station. This study investigates: inter‐ and intraseasonal trends relative abundance; changes to proportion southwestern subpopulation represented by Bay; distribution; occupancy. Sighting...

Endangered Australian southern right whales, Eubalaena australis, are vulnerable to threats from human activities, particularly at calving aggregation areas. As the population increases, new areas being established, which important monitor. In Encounter Bay/Lacepede Bay region, South Australia, distribution, relative abundance, residency and site fidelity were studied using historical sightings (n = 1071, 1970–2013) photo-identified individuals 191, 2006–2019). Whales observed throughout...
The Curtin University Great Australian Bight Right Whale Study (GABRWS) delivers cost effective scientific research to inform risk-based decision making and conservation management of Environment Protection Biodiversity Conservation Act 1999 (EPBC Act) listed endangered southern right whales (Eubalaena australis). GABRWS has operated annually on Yalata Aboriginal lands at the Head in Australia’s largest calving ground, between 1991 2019, Fowlers Bay Nuyts Archipelago Marine Park 2013 2019....
Abstract A universal scaling relationship exists between organism abundance and body size 1,2 . Within ocean habitats this deviates from that generally observed in terrestrial systems 2–4 , where marine macro-fauna display steeper size-abundance than expected. This is indicative of a fundamental shift food-web organization, yet conclusive mechanism for pattern has remained elusive. We demonstrate while fishing partially contributed to the reduced larger organisms, effect comes turbulence:...
