Although extensively studied and classified, to date few attempts have been made to examine geographic variation in their calls. In this study, we examined geographic variation in simple contact calls (SCCs), specifically those that consist only of broadband pulsed trains, among four Canadian beluga populations from the Eastern Beaufort Sea (EBS), the Eastern High Arctic-Baffin Bay, St. Lawrence Estuary (SLE), and the Western Hudson Bay. Five acoustic parameters were measured for each call and compared among populations using multivariate discriminant analysis. Results of our study indicate that there is a degree of variation in SCCs among these four populations, with the most geographically distant populations of the SLE and EBS displaying the greatest degrees of dissimilarity in SCC structure relative to geographically closer populations. Further, these results align with genetic variation of Canadian beluga populations previously described in the literature. This study is the first descriptive population comparison of SCCs for beluga and establishes a baseline for continued work into this developing area of research.</p>","PeriodicalId":18725,"journal":{"name":"Marine Mammal Science","volume":"40 2","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/mms.13095","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139034949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present the first insights from SRW satellite-tracked from the SG/IG feeding ground, habitat use patterns in the Scotia Arc, and movements to Antarctic habitats. Photo-identification comparisons to calving and feeding areas across the South Atlantic and a review of sightings of cetaceans reported from Bird Island (west of SG/IG) since 1979 illuminate long-term habitat use patterns in SG/IG. We present the first recorded migratory movement between SG/IG and multiple countries: Argentina, Uruguay, and Brazil. Photo-identification (1) linked SG/IG to a female SRW with a long-term sighting history in Brazil, and (2) provided the first match between SG/IG and the western Antarctic Peninsula, suggesting the latter could extend the feeding area for southwest Atlantic SRW. Satellite tracking and opportunistic sightings suggest that shelf and coastal waters west of SG/IG represent an important multi-season SRW feeding habitat and add to our overall understanding of habitats and ranges occupied by recovering southwest Atlantic SRW.</p>","PeriodicalId":18725,"journal":{"name":"Marine Mammal Science","volume":"40 2","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/mms.13089","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138508223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The seasonal abundance and distribution of cetaceans in the Sinop region, one of the essential fishing areas of the Black Sea, were estimated with line-transect data. Dedicated boat-based visual observations were conducted in four seasons between May 2019 and March 2020. Average estimates of abundance in the region over all seasons were 1,058 individuals for Black Sea harbor porpoises (<i>Phocoena phocoena relicta</i>; <i>CV</i> = 19.25%, 95% CI[725, 1,542]), 188 individuals for Black Sea bottlenose dolphins (<i>Tursiops truncatus ponticus</i>; <i>CV</i> = 21.67%, 95% CI[123, 289]), and 311 individuals for Black Sea common dolphin (<i>Delphinus delphis ponticus</i>; <i>CV</i> = 16.77%, 95% CI[123, 427]). The highest estimates for all three species were obtained in the spring. Harbor porpoises and bottlenose dolphins were present in the study area throughout the year, while common dolphins left the region in winter. These findings offer valuable insights that can guide and inform future conservation strategies, aligning with national and international frameworks for the protection of these cetacean species.</p>","PeriodicalId":18725,"journal":{"name":"Marine Mammal Science","volume":"40 2","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/mms.13092","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138508241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"First direct observation of a successful southern right whale (Eubalaena australis) birth in South African coastal waters","authors":"Loraine Shuttleworth,&nbsp;Ash Appleby,&nbsp;Robin Appleby,&nbsp;Els Vermeulen","doi":"10.1111/mms.13091","DOIUrl":"10.1111/mms.13091","url":null,"abstract":"&lt;p&gt;Southern right whale females (&lt;i&gt;Eubalaena australis&lt;/i&gt;, hereafter SRWs) usually migrate between higher latitudes where they forage in summer to coastal areas at lower latitudes where they give birth and nurse their young in winter (Best, &lt;span&gt;2000&lt;/span&gt;). In South Africa, the SRW calving season extends between late June to late October, with a birthing peak in August (Best, &lt;span&gt;1994&lt;/span&gt;). This predictable coastal presence has enabled population monitoring since the late 1960s by means of annual aerial surveys (e.g., Best, &lt;span&gt;1990&lt;/span&gt;; Best et al., &lt;span&gt;2001&lt;/span&gt;). In addition to monitoring population recovery postwhaling, these long-term surveys have also allowed for the observational assessment of reproductive parameters. As such, the age at first parturition in the population was estimated at 8 years with an average calving interval of 3 years and an estimated gestation length of 12–13 months (Best, &lt;span&gt;1994&lt;/span&gt;; Best et al., &lt;span&gt;2001&lt;/span&gt;). However, despite these long-term research efforts, very little is known regarding the actual birthing event in SRWs (Best, &lt;span&gt;1994&lt;/span&gt;). Three accounts of possible SRW births off the coast of South Africa have briefly been discussed in Best (&lt;span&gt;1970&lt;/span&gt;) and Best (&lt;span&gt;1981&lt;/span&gt;) but they all relate to anecdotal evidence from distant shore-based observations.&lt;/p&gt;&lt;p&gt;Documentation of SRW births is equally rare across calving grounds throughout the southern hemisphere. In 2012, an unsuccessful birth was documented in Argentina (Península Valdés) from a whale watching vessel and reported in Sironi et al. (&lt;span&gt;2019&lt;/span&gt;). The authors suggested that there were a few possible factors indicating that this was an abnormal parturition including the repeated protrusion and withdrawal of the calf, lengthy time-period before full expulsion of the calf, and resighting of the female without a calf (Sironi et al., &lt;span&gt;2019&lt;/span&gt;). However, despite the increasing boat-based presence around SRWs, mostly in the form of whale-based tourism, close and detailed observation of a successful birth has, to our knowledge, never been directly observed and documented. Therefore, here we report the first documented successful SRW birth observed along the South African coast, supplemented with photographic evidence.&lt;/p&gt;&lt;p&gt;In early July 2022, the commercial whale-watching boat &lt;i&gt;Miroshca&lt;/i&gt; (length: 18 m; engine specifications: two John Deere 9 L inboard engines) of the whale-watching company Southern Right Charters encountered a lone SRW in Walker Bay, Hermanus, South Africa. For three to four consecutive days, what appeared to be the same animal was observed in approximately the same location (near 34°26.57′S, 19°15.40′E) performing short but steep fluking dives. As this type of behavior is typically enjoyed by tourists and rare to see repetitively, the vessel deliberately headed to the same coordinates during each trip considering the high likelihood of such an exciting encounter.
