Recreational boats are common in many coastal waters, yet their effects on cetaceans and other sensitive marine species remain poorly understood. To address this knowledge gap, we used drone video footage recorded from a recreational boat to quantify how harbour porpoises (
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...
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. We latest catalog with wintering...
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...
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...
Abstract Cetacean species are highly mobile, most of them regularly travelling over long distances, thereby presenting complex obstacles to their conservation. Identification critical habitats, specifically those parts a cetacean’s range that essential for day‐to‐day survival and maintaining healthy population growth rate, is necessary effective protection. This study presents summary the data on cetacean sightings during surveys covered substantial Russian Far East coastal waters from...
Humpback whales Megaptera novaeangliae undertake extensive annual migrations, have complex migratory patterns, and held several mammalian long-distance movement records. Here, we report on a whale known to feed in the Russian Far East that was sighted breeding areas either side of North Pacific, Mariana Islands Mexico, less than 1 yr (357 d apart). This is longest published distance (11261 km great-circle route) between 2 unique sightings photo-identified humpback date. To understand context...
Abstract Killer whales ( Orcinus orca ) have group‐specific call repertoires that can be used to track groups and populations using passive acoustic monitoring. To provide a detailed description of the Icelandic killer whale repertoire its variation, we analyzed data collected in five locations between 1985 2016. Calls were classified manually, CART random forest analyses employed validate manual classification. A total 91 categories (including types subtypes) defined. Most recorded more...
Socially transmitted behavioural patterns (i.e. cultural traditions) have been observed in many whale species from large baleen whales to small dolphins. However, no traditions described so far beaked whales, an elusive and poorly studied group of toothed whales. In this study we report a local population Baird's Berardius bairdii, the Commander Islands regularly using shallow area with depths less than 300 m which is uncharacteristic for species. We analysed distribution behaviour mtDNA...
Top predators affect ecosystems by controlling prey populations both directly through consumption and indirectly fear (Brown et al., 1999; Suraci 2016). The threat of predation affects the foraging spatial behavior species can even drive emigration from areas with higher risk (Bowlby 2023; Jorgensen 2019; Harbor porpoises (Phocoena phocoena) are smallest one most abundant widely distributed cetaceans in Northern Hemisphere (Bjørge & Tolley, 2018). From what we know, main harbor killer whales...
Abstract Killer whale call repertoires can provide information on social connections among groups and populations. whales in Iceland Norway exhibit similar ecology behavior, are genetically related, presumed to have been contact before the collapse of Atlanto‐Scandian herring stock 1960s. However, photo‐identification suggests no recent movements between but regular movement Shetland. Acoustic recordings collected 2005 2016 Iceland, Norway, Shetland were used undertake a comprehensive...
Abstract Killer whales are top predators in marine trophic chains, and therefore their feeding preferences can substantially affect the abundance of species on lower levels. known to feed many different types prey from small fish large whales, but a given killer whale population usually focuses specific type prey. Stable isotope analysis is widely used study diets, because direct observations often impossible. habits western North Pacific poorly studied, large‐scale stable provides unique...
