To investigate movements of humpback whales among breeding and migratory areas Oceania in the South Pacific Ocean, comparisons individually identified were undertaken using catalogues from New Caledonia, Tonga, Zealand, Cook Islands French Polynesia. These locations probably represent wintering grounds or for Group V VI stocks, as recognised by International Whaling Commission management purposes. Comparisons also made to small samples photos Colombia, Ecuador Antarctic Peninsula,...
Humpback whale song is a culturally transmitted behavior. Human language, which also transmitted, has statistically coherent parts whose frequency distribution follows power law. These properties facilitate learning and may therefore arise because of their contribution to the faithful transmission language over multiple cultural generations. If so, we would expect find them in other systems. In this study, applied methods based on infant speech segmentation 8 years humpback recordings,...
The humpback whale population of New Caledonia appears to display a novel migratory pattern characterized by multiple directions, long paths and frequent pauses over seamounts other shallow geographical features. Using satellite-monitored radio tags, we tracked 34 whales for between 5 110 days, travelling 270 8540 km on their southward migration from breeding ground in southern Caledonia. Mean speed was 3.53±2.22 h −1 , while movements within the averaged 2.01±1.63 . tag data demonstrate...

Bottlenose dolphins (Tursiops truncatus) occupy a wide range of coastal and pelagic habitats throughout tropical temperate waters worldwide. In some regions, "inshore" "offshore" forms or ecotypes differ genetically morphologically, despite no obvious boundaries to interchange. Around New Zealand, bottlenose inhabit 3 regions: Northland, Marlborough Sounds, Fiordland. Previous demographic studies showed interchange individuals among these populations. Here, we describe the genetic structure...
Humpback whale seasonal migrations, spanning greater than 6500 km of open ocean, demonstrate remarkable navigational precision despite following spatially and temporally distinct migration routes. Satellite-monitored radio tag-derived humpback tracks in both the South Atlantic Pacific include constant course segments 200 km, each several days continuous movement. The whales studied here maintain these directed movements, often with better 1° precision, effects variable sea-surface currents....
Male humpback whales produce a long, complex, and stereotyped song on low-latitude breeding grounds; they also sing while migrating to from these locations, occasionally in high-latitude summer feeding areas. All males population the current version of constantly evolving display and, within an ocean basin, populations similar songs; however, this sharing can be complex. In western central South Pacific region there is repeated cultural transmission types eastern Australia other eastward....

Abstract Aim Accurate predictions of cetacean distributions are essential to their conservation but limited by statistical challenges and a paucity data. This study aimed at comparing the capacity various algorithms deal with biases commonly found in nonsystematic surveys evaluate potential for citizen science data improve habitat modelling predictions. An endangered population humpback whales ( Megaptera novaeangliae ) breeding ground was used as case study. Location New Caledonia, Oceania....
In understanding the impact of commercial whaling, it is important to estimate mixing low latitude breeding populations on Antarctic feeding grounds, particularly endangered humpback whale Oceania. This paper estimates degree genetic differentiation among putative Oceania (New Caledonia, Tonga, Cook Islands and French Polynesia) Australia (western eastern Australia) using ten microsatellite loci mtDNA, assesses power data for a mixed-stock analysis, determines ways improve statistical future...
Whale- and dolphin-watching activities are demonstrating a strong growth worldwide, raising concern of their potential impacts on cetacean populations emphasising the need for management. Humpback whales recently have become focus an important tourism industry in South Pacific, particularly New Caledonia, where operators small population humpback main breeding ground. Despite considerable since it began 1995, remains unregulated. Between 2005 2007, study was conducted to assess impact...
Abstract Every winter, (male) humpback whales (Megaptera novaeangliae) produce long complex songs. Song content is dynamic and singers incorporate changes as they occur, thus song shared through cultural transmission. We compared songs recorded in winter migratory termini Tonga, New Caledonia, Eastern Australia, on migration paths off Australia Zealand, the of 1994. Seven themes were by all regions, with an additional two but Tonga. Differences regional variants most pronounced between...
Humpback whales have a continually evolving vocal sexual display, or “song,” that appears to undergo both evolutionary and “revolutionary” change. All males within population adhere the current content arrangement of song. Populations an ocean basin share similarities in their songs; this sharing is complex as multiple variations song (song types) may be present region at any one time. To quantitatively investigate similarity types, songs were compared individual singer level using...
Abstract For cetaceans, population structure is traditionally determined by molecular genetics or photographically identified individuals. Acoustic data, however, has provided information on movement and with less effort cost than traditional methods in an array of taxa. Male humpback whales (Megaptera novaeangliae) produce a continually evolving vocal sexual display, song, that similar among all males population. The rapid cultural transmission (the transfer behavior between conspecifics...
In the context of a changing climate, understanding environmental drivers marine megafauna distribution is important for conservation success. The extent humpback whale breeding habitats and impact temperature variation on their availability are both unknown. We used 19 years dedicated survey data from seven countries territories Oceania (1,376 days), to investigate habitat diversity adaptability climate change. At fine scale (1 km resolution), seabed topography was identified as an...
Cultural transmission of behaviour is important in a wide variety vertebrate taxa from birds to humans. Vocal traditions and vocal learning provide strong foundation for studying culture its both humans cetaceans. Male humpback whales ( Megaptera novaeangliae ) perform complex, culturally transmitted song displays that can change evolutionarily (through accumulations small changes) or revolutionarily (where population rapidly adopts novel song). The degree coordination conformity underlying...
Culture presents a second inheritance system by which innovations can be transmitted between generations and among individuals. Some vocal behaviours present compelling examples of cultural evolution. Where modifications accumulate over time, such process become cumulative The existence evolution in non-human animals is controversial. When physical products do not exist, may clearly visible time. Here, we investigate whether the constantly evolving songs humpback whales ( Megaptera...
Variation in reproductive success is a fundamental prerequisite for sexual selection to act upon trait. Assessing such variation crucial understanding species’ mating system and offers insights into population growth. Parentage analyses cetaceans are rare, the underlying forces of acting on their behaviours remain poorly understood. Here, we combined 25 years photo-identification genetic data assess patterns male autonomy New Caledonian (Oceania, South Pacific) humpback whale breeding...
Animals can communicate using visual and acoustic displays to convey information conspecifics. In some cases, such are produced in highly stereotyped repetitive sequences. Here we use a quantitative analysis technique, the Levenshtein distance, assess similarity sequences of at both population individual levels. We review two existing variations method present new that complement extend these techniques. Three methods include median string sequence three normalisation original equation....
Abstract Humpback whales ( Megaptera novaeangliae ) are known for their nearshore distribution during the breeding season, but pelagic habitat use patterns remain mostly unexplored. From 2016 to 2018, 18 humpback were equipped with depth-recording satellite tags (SPLASH10) shed light on environmental and social drivers of seamount association around New Caledonia in western South Pacific. Movement paths spatially structured shallow seamounts (<200 m). Indeed, two males stopped over Lord...
