In cetaceans, exhaled breath condensate (blow)—a mixture of cells, mucus and fluids expelled through the force of a whale’s exhale—is a unique sampling matrix for hormones, bacteria and genetic material, among others. Especially the detection of steroid hormones, such as cortisol, is being investigated as stress indicators in several species. As the only Citation: Reckendorf, A.; Schmicke, native cetacean in Germany, harbor porpoises (Phocoena phocoena) are of special conservation concern M.; Bunskoek, P.; Anderson Hansen, and research interest. So far, strandings and live captures have been the only method to obtain K.; Thybo, M.; Strube, C.; Siebert, U. -
Cetacean Occurrence in the Gulf of Alaska from Long-Term Passive
Marine Biology (2021) 168:72 https://doi.org/10.1007/s00227-021-03884-1 ORIGINAL PAPER Cetacean occurrence in the Gulf of Alaska from long‑term passive acoustic monitoring Ally Rice1 · Ana Širović1,2 · Jennifer S. Trickey1 · Amanda J. Debich1,3 · Rachel S. Gottlieb1 · Sean M. Wiggins1 · John A. Hildebrand1 · Simone Baumann‑Pickering1 Received: 23 November 2020 / Accepted: 11 April 2021 © The Author(s) 2021 Abstract The Gulf of Alaska is an important habitat for a diverse array of marine mammals, many of which were severely depleted by historical whaling. To study current cetacean distributions in this region, passive acoustic monitoring was used to detect species-specifc call types between 2011 and 2015 at fve locations spanning the continental shelf, slope, and ofshore sea- mounts. Spatial and temporal detection patterns were examined for nine species to compare diferences in behavior and habitat use. Mysticetes showed seasonal increases in calling that indicated possible behavioral shifts between feeding and breeding in blue (Balaenoptera musculus), fn (B. physalus), and humpback (Megaptera novaeangliae) whales, and matched known migration timing of gray whales (Eschrichtius robustus). Interannual changes in blue and fn whale calling may relate to the marine heat wave that began in 2013 and lasted through the end of the monitoring period. Odontocete detections revealed unique spatial distributions, with killer whales (Orcinus orca) most common on the continental shelf and sperm whales (Physeter macrocephalus) most common on the continental slope, where detections occurred year-round. Beaked whales showed both spatial and temporal separation: Baird’s beaked whale (Berardius bairdii) detections were highest at Quinn Seamount in the spring, Cuvier’s (Ziphius cavirostris) at Pratt Seamount in winter, and Stejneger’s (Mesoplodon stejnegeri) on the continental slope in the fall. -

List of Marine Mammal Species and Subspecies Written by The
List of Marine Mammal Species and Subspecies Written by the Committee on Taxonomy The Ad-Hoc Committee on Taxonomy , chaired by Bill Perrin, has produced the first official SMM list of marine mammal species and subspecies. Consensus on some issues was not possible; this is reflected in the footnotes. This list will be revisited and possibly revised every few months reflecting the continuing flux in marine mammal taxonomy. This list can be cited as follows: “Committee on Taxonomy. 2009. List of marine mammal species and subspecies. Society for Marine Mammalogy, www.marinemammalscience.org, consulted on [date].” This list includes living and recently extinct species and subspecies. It is meant to reflect prevailing usage and recent revisions published in the peer-reviewed literature. Author(s) and year of description of the species follow the Latin species name; when these are enclosed in parentheses, the species was originally described in a different genus. Classification and scientific names follow Rice (1998), with adjustments reflecting more recent literature. Common names are arbitrary and change with time and place; one or two currently frequently used in English and/or a range language are given here. Additional English common names and common names in French, Spanish, Russian and other languages are available at www.marinespecies.org/cetacea/ . The cetaceans genetically and morphologically fall firmly within the artiodactyl clade (Geisler and Uhen, 2005), and therefore we include them in the order Cetartiodactyla, with Cetacea, Mysticeti and Odontoceti as unranked taxa (recognizing that the classification within Cetartiodactyla remains partially unresolved -- e.g., see Spaulding et al ., 2009) 1. -
Balaenoptera Bonaerensis – Antarctic Minke Whale
Balaenoptera bonaerensis – Antarctic Minke Whale compared to B. bonaerensis. This smaller form, termed the “Dwarf” Minke Whale, may be genetically different from B. bonaerensis, and more closely related to the North Pacific Minke Whales, and thus has been classified B. acutorostrata (Wada et al. 1991; IWC 2001). This taxonomic position, although somewhat controversial, has been accepted by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), and the Convention on Migratory Species (CMS). Assessment Rationale The current IWC global estimate of abundance of Antarctic Dr. Meike Scheidat Minke Whales is about 500,000 individuals. The abundance estimates declined from about 700,000 for the second circumpolar set of abundance survey cruises Regional Red List status (2016) Least Concern* (1985/86 to 1990/91) to about 500,000 for the third National Red List status (2004) Least Concern (1991/92 to 2003/04). Although this decline was not statistically significant, the IWC Scientific Committee does Reasons for change No change consider these results to reflect a change. However, Global Red List status (2008) Data Deficient whether this change is genuine or attributed to greater proportions of pack ice limiting the survey extent, has not TOPS listing (NEMBA) (2007) None yet been determined. More detailed results from an CITES listing (1986) Appendix I assessment model are available for the mid-Indian to the mid-Pacific region, and suggest that the population Endemic No increased to a peak in 1970 and then declined, with it *Watch-list Data being unclear whether this decline has levelled off or is still continuing past 2000. -
Description of a New Species of Beaked Whale (Berardius) Found in the North Pacific
www.nature.com/scientificreports OPEN Description of a new species of beaked whale (Berardius) found in the North Pacifc Received: 30 November 2018 Tadasu K. Yamada1, Shino Kitamura2,3, Syuiti Abe3, Yuko Tajima1, Ayaka Matsuda3, Accepted: 4 July 2019 James G. Mead4 & Takashi F. Matsuishi3,5 Published: xx xx xxxx Two types of Berardius are recognised by local whalers in Hokkaido, Japan. The frst is the ordinary Baird’s beaked whale, B. bairdii, whereas the other is much smaller and entirely black. Previous molecular phylogenetic analyses revealed that the black type is one recognisable taxonomic unit within the Berardius clade but is distinct from the two known Berardius species. To determine the characteristics of the black type, we summarised external morphology and skull osteometric data obtained from four individuals, which included three individuals from Hokkaido and one additional individual from the United States National Museum of Natural History collection. The whales difered from all of their congeners by having the following unique characters: a substantially smaller body size of physically mature individuals, proportionately shorter beak, and darker body colour. Thus, we conclude that the whales are a third Berardius species. Beaked whales (Family Ziphiidae, Odontoceti, Cetacea) include the second largest number of species among toothed whale families. Teir preference for deep ocean waters, elusive habits, and long dive capacity1 make beaked whales hard to see and inadequately understood. A total of 22 species are currently recognized in six genera (Berardius, Hyperoodon, Indopacetus, Mesoplodon, Tasmacetus, and Ziphius)2. Te genus Berardius has two species, Baird’s beaked whale Berardius bairdii, found in the North Pacifc and adjacent waters, and Arnoux’s beaked whale B. -
The Bowhead Vs. the Gray Whale in Chukotkan Aboriginal Whaling IGOR I
ARCTIC VOL. 40, NO. 1 (MARCH 1987) P. 16-32 The Bowhead vs. the Gray Whale in Chukotkan Aboriginal Whaling IGOR I. KRUPNIK’ (Received 5 September 1984; accepted in revised form 22 July 1986) ABSTRACT. Active whaling for large baleen whales -mostly for bowhead (Balaena mysricetus) and gray whales (Eschrichrius robustus)-has been practiced by aborigines on the Chukotka Peninsula since at least the early centuries of the Christian era. Thehistory of native whaling off Chukotka may be divided into four periods according to the hunting methods used and the primary species pursued: ancient or aboriginal (from earliest times up to the second half of the 19th century); rraditional (second half of the 19th century to the1930s); transitional (late 1930s toearly 1960s); and modern (from the early 1960s). The data on bowhead/gray whale bone distribution in theruins of aboriginal coastal sites, available catch data from native settlements from the late 19th century and local oral tradition prove to be valuable sources for identifying specific areas of aboriginal whaling off Chukotka. Until the 1930s, bowhead whales generally predominated in the native catch; gray whales were hunted periodically or locally along restricted parts of the coast. Some 8-10 bowheads and 3-5 gray whales were killed on the average in a “good year”by Chukotka natives during the early 20th century. Around the mid-20th century, however, bowheads were completely replaced by gray whales. On the basis of this experience, the author believes that the substitution of gray whales for bowheads, proposed recently by conservationists for modemAlaska Eskimos, would be unsuccessful. -

Due to seasonal upwelling (Fraga, 1981), the NWIP sustains high productivity and high biodiversity, including almost 300 species of fish (Solørzano et al., 1988) and over 75 species of cephalopods (Guerra, 1992). -
FC Inshore Cetacean Species Identification
Falklands Conservation PO BOX 26, Falkland Islands, FIQQ 1ZZ +500 22247 [email protected] www.falklandsconservation.com FC Inshore Cetacean Species Identification Introduction This guide outlines the key features that can be used to distinguish between the six most common cetacean species that inhabit Falklands' waters. A number of additional cetacean species may occasionally be seen in coastal waters, for example the fin whale (Balaenoptera physalus), the humpback whale (Megaptera novaeangliae), the long-finned pilot whale (Globicephala melas) and the dusky dolphin (Lagenorhynchus obscurus). A full list of the species that have been documented to date around the Falklands can be found in Appendix 1. Note that many of these are typical of deeper, oceanic waters, and are unlikely to be encountered along the coast. The six species (or seven species, including two species of minke whale) described in this document are observed regularly in shallow, nearshore waters, and are the focus of this identification guide. Questions and further information For any questions about species identification then please contact the Cetaceans Project Officer Caroline Weir who will be happy to help you try and identify your sighting: Tel: 22247 Email: [email protected] Useful identification guides If you wish to learn more about the identification features of various species, some comprehensive field guides (which include all cetacean species globally) include: Handbook of Whales, Dolphins and Porpoises by Mark Carwardine. 2019.

A Brief Review of the Genetic Studies on Dwarf Minke Whale Based on Jarpa Samples
SC/D06/J8 A BRIEF REVIEW OF THE GENETIC STUDIES ON DWARF MINKE WHALE BASED ON JARPA SAMPLES Luis A. Pastene Institute of Cetacean Research, Toyomi-cho 4-5, Chuo-ku, Tokyo 104-0055, Japan ABSTRACT Prior to the JARPA surveys ‘dwarf’ minke whales were only believed to be found between 7-41°S. However the locality of the JARPA catches in Areas IV and V was mainly between 55-62°S (one animal was caught at 65°S), showing that the ‘dwarf’ minke whale is found much further south than shown by the previous data. A total of 16 ‘dwarf’ minke whales were sampled by JARPA and these animals were examined genetically with the purpose to investigate their relationship to the southern ‘ordinary’ minke whale and to minke whales in the Northern Hemisphere. Early studies showed that the degree of mtDNA divergence between both southern minke whales was large and similar to that found between southern ‘ordinary’ minke whale and Northern Hemisphere minke whales. Phylogenetic analyses showed that the ‘dwarf’ minke whale was more closely related to Northern Hemisphere minke whales. In 1993 the Scientific Committee recommended the inclusion of the ‘dwarf’ minke whale in the Schedule, so that catch limits for Antarctic minke whales recognise the distinction between the two southern minke whales. The genetic analysis conducted using JARPA samples of the southern ‘ordinary’ and ‘dwarf’ minke whales assisted greatly to the taxonomic review of minke whale conducted by Rice (1998), which confirmed the existence of two species, the larger, Antarctic minke whale Balaenoptera bonaerensis confined to the Southern Hemisphere, and the smaller, common minke whale B. -
Gray Whales - Current Status and Strandings
San Francisco Bay National Wildlife Refuge Complex Tideline Newsletter Archives Gray whales - current status and strandings by Doreen Moser and Frances Gulland As winter begins here in California, so does the annual gray whale (Eschrichtius robustus) migration. In November, the whales begin their 5,000-mile journey south ward from Alaska’s Bering and Chukchi Seas. During December and January thou sands of these whales are seen migrating along our coast. By January, pregnant fe males are first to reach the calving lagoons along the West coast of Baja California, Mexico. Soon they are joined by the other adults and juveniles. The females give birth to their calves in the lagoons, usually for the first time when eight years old. In February, the animals begin another 5,000 mile jour ney northward returning to Alaska. During the spring months, cow-calf pairs can be seen migrating very close to shore. These 15-foot calves nurse constantly, as they migrate back to the summer feeding grounds. As you stand along the shore, how do you know you are looking at a gray whale? You can usually spot them by their heart-shaped blow. They surface regularly every three to five minutes when migrating, and usually blow three to five times. They swim between 7 and 9 kms per hour. Gray whales are medium sized whales, reaching up to 45 feet in length and weighing 45 tons. As in other baleen whales, females are larger than the males. Gray whales can be distin guished from other whales because they lack a dorsal (back) fin. -

SC/63/RMP10 SATELLITE TRACKING OF A COMMON MINKE WHALE IN THE COASTAL WATERS OFF HOKKAIDO, NORTHERN JAPAN IN 2010 Toshiya Kishiro and Tomio Miyashita National Research Institute of Far Seas Fisheries, 2-12-4 Fukuura, Kanazawa-ku, Yokohama, Kanagawa 236-8648, Japan Contact e-mail: [email protected] ABSTRACT Using a research vessel, Shonan-maru No.2, the sighting and satellite tagging survey for common minke whales was conducted in the coastal waters off Kushiro, southeastern coast of Hokkaido, northern Japan in 2010 autumn season. The period of survey was from 6 September to 4 October. During the survey, a total of 878.2 n. miles was searched with the restricted closing mode, and 28 schools/ 30 individuals of common minke whales were sighted (primary sightings: 20/21, secondly sightings: 8/9). Using a handy air gun, a satellite tag (Argos transmitter) was attached on one common minke whale in the 15 n. miles offing of Kiritappu on 13 September. The estimated body length of the whale was 7.8m. The electric wave reception by the satellite was started on 15 September, and the movement of the whale was tracked for a period of 27 days. Estimated position of the tagged whale was located in the west coast off the cape of Erimo, and moved to east –west courses along the coastline. These results suggested that the tagged whale stayed in the coastal waters off Kushiro, for at least four weeks in autumn season. The tracking results were not contradicted with the expected migration routes of the whales.
