For the 40 years after end of commercial whaling in 1976, humpback whale populations North Pacific Ocean exhibited a prolonged period recovery. Using mark–recapture methods on largest individual photo-identification dataset ever assembled for cetacean, we estimated annual ocean-basin-wide abundance species from 2002 through 2021. Trends estimates describe strong post-whaling era population recovery 16 875 (± 5955) to peak estimate 33 488 4455) 2012. An apparent 20% decline 2012 2021, 26 662...
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 was built through a broad collaboration combining 39 separate curated photo-ID catalogs, supplemented with community science data. Data from throughout were aggregated into 13 regions, including six breeding feeding one migratory corridor. All images compared minimal...
Cultural evolution is a powerful process shaping behavioural phenotypes of many species including our own. Killer whales are one the with relatively well-studied vocal culture. Pods have distinct dialects comprising mix unique and shared call types; calves adopt repertoire their matriline through social learning. We review different aspects killer whale acoustic communication to provide insights into cultural transmission gene-culture co-evolution processes that produce extreme diversity...
Abstract There are two recognized species in the genus Berardius , Baird's and Arnoux's beaked whales. In Japan, whalers have traditionally forms of whales, common “slate‐gray” form a smaller, rare “black” form. Previous comparison mt DNA control region sequences from three black specimens to gray around Japan indicated that comprise different stocks potentially species. We expanded sampling include haplotypes 178 whales across their range North Pacific. identified five additional Aleutian...
Killer whale populations may differ in genetics, morphology, ecology, and behavior. In the North Pacific, two sympatric ("resident" "transient") specialize on different prey (fish marine mammals) retain reproductive isolation. eastern Atlantic, whales from same have been observed feeding both fish mammals. Fish-eating Pacific "residents" are more genetically related to Atlantic killer than mammal-eating "transients." this paper, a comparison of frequency variables calls recorded four...
Abstract Forestalling the decline of global biodiversity requires urgent and transformative action at all levels government society, particularly in Arctic Ocean adjacent seas where rapid changes are already underway. Amid growing scientific support mounting pressure, majority nations have committed to most ambitious conservation targets yet. However, without an approach that inclusively equitably reconciles sustainable ocean use, these will likely go unmet. Here, we present ArcNet: a...
ABSTRACT The problem of categorization arises in any classification system because classes should be discrete while the characteristics most natural objects and aspects nature are more or less gradual. In systematics, this usually is solved by creating several levels categories, such as class, order, family, genus species. existing killer whale call classification, only two occur—call type subtype. paper we describe structural categories at a broader level than sounds whales compare these...
Abstract Humpback whales migrate seasonally from high latitude feeding areas to lower breeding for mating and calving. In 2004–2006, a North Pacific basin‐wide study called SPLASH was conducted as an international collaboration among various groups of researchers. The Russian Far East consists multiple during , 102 were identified compared catalogs areas. Our goal in this further investigate the migratory destinations using total 1,459 photographs 2004 2014.

Ultrasonic whistles were previously found in North Atlantic killer whales and suggested to occur eastern Pacific based on the data from autonomous recorders. In this study ultrasonic recordings two encounters with offshore ecotype one encounter western of unknown ecotype. All highly stereotyped all but had downsweep contours. These results demonstrate that specific sound categories can be shared by different ocean basins.
Abstract The social structure of Baird's beaked whales is completely unstudied, and it unknown if either females or males form long‐term associations occur in stable groups. In this paper we summarize our observations individually identified animals over the span 6 yr to provide insight on their structure. We have 122 whales, with 28 them encountered three times more thus included analysis found that exhibited nonrandom patterns some individuals preferentially associating each other. Whales...
Abstract Killer whales produce repertoires of stereotyped call types that are primarily transmitted vertically through social learning, leading to dialects between sympatric pods. The potential function these remains untested. In this study, we compared the reaction Kamchatkan fish‐eating killer playbacks calls from same and different After playback recordings a pod, in three cases changed direction their movement toward boat, no changes were observed. pod (either or unit within pod), seven...
ABSTRACT Here we present an acoustic approach for reliable sexing in four whistling duck species from the genus Dendrocygna and compare it with molecular cloacal inspection techniques. In examined species, White-faced Whistling Duck D. viduata, Fulvous bicolor, Cuban arborea Red-billed autumnalis, sexes are indistinguishable by appearance. However all show strong sexual differences structure of their species-specific loud whistles. For 59 birds, acoustic-based showed 100% accordance to DNA...
Mitochondrial DNA (mtDNA) differences between humpback whales on different feeding grounds can reflect the cultural transmission of migration destinations over generations, and therefore represent one very few cases gene-culture coevolution identified in animal kingdom. In Russian Pacific waters, photo-identification (photo-ID) studies have shown minimal interchange off Commander Islands those Karaginsky Gulf, regions that are separated by only 500 km previously been lumped together as a...
