We studied the foraging behavior of these whales at the mouth of the Chesapeake Bay, Virginia during winter from 2017 to 2022. While shipping channels here reach depths of up to 30 m, most of the area is 11–15 m deep. This shallow‐water environment poses physical constraints on classical humpback whale feeding modes. We deployed 20 digital acoustic tags (DTAGs) on humpback whales and identified foraging lunges from accelerometer data, detecting 788 lunges from 10 animals. Tagged whales averaged a single lunge per dive, lunging primarily in a horizontal orientation, with limited maneuvering compared to other study sites. Our results indicate that some elements of humpback whale foraging behavior are conserved across environments, but that the shallow depths in our study area constrain how animals are able to feed. The relatively high lunge rates we observed suggest this area is an important foraging ground. However, foraging in shipping channels increases the risk of ship strikes, which frequently occur in this area.","PeriodicalId":18725,"journal":{"name":"Marine Mammal Science","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142263900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two vibrissal parameters that differ in pinnipeds are shape and number.

As there is disagreement with respect to which phocid vibrissae lack the undulation, we systematically collected information on vibrissal type. We have documented that all eared seals we examined, walruses, Mediterranean monk seals, bearded, and leopard seals have smooth vibrissae. All other phocids have undulated vibrissae, except for Ross seals and Hawaiian monk seals, which have partially undulated vibrissae. Moreover, we quantified and documented the existence of vibrissae from photos revealing otariids to have 20–43 mystacial vibrissae/pad, no rhinal vibrissae, 1–2 supraorbital vibrissae above each eye, and phocids to have 15–97 mystacial vibrissae/pad, 0–2 rhinal vibrissae/nostril, 1–9 supraorbital vibrissae above each eye, all averages determined from counts made from photos. Walruses have the maximum number of mystacial vibrissae amounting to 198 vibrissae/pad on average, but almost all walruses lack rhinal and supraorbital vibrissae. Vibrissae were found at the upper lip and on the lower jaw in some pinnipeds.","PeriodicalId":18725,"journal":{"name":"Marine Mammal Science","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142206324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we sequenced three genetic markers, the control region (CR) and cytochrome b (cytb) of the mitochondrial genome and the first intron of the nuclear muscle actin gene ACTA2, of two biopsy samples collected in 2021, and revealed unambiguous clustering with sequences previously attributed to Deraniyagala's beaked whale (Mesoplodon hotaula). Phylogenetic analysis of complete mitogenomes strongly supported the close relationship between the Deraniyagala's beaked whale and the ginkgo‐toothed beaked whale (M. ginkgodens). Whole‐genome sequencing suggested a high degree of heterozygosity in the Deraniyagala's beaked whale. Ancient inbreeding may have had a greater impact than the recent inbreeding on Deraniyagala's beaked whales, but more samples are needed to draw a firm conclusion. The approximate effective population size of Deraniyagala's beaked whale was found lowest among seven examined ziphiids, which has been experiencing a steady decline since ~300,000 ya. Therefore, we suggest that the conservation status of Deraniyagala's beaked whales should be assessed when essential information is available.

Given that bycatch levels display strong variations in space and time, knowledge of individual fishery‐marine mammal interaction will likely achieve working solutions. Here, we quantify marine mammal bycatch in the trawl fishery of the San Matías Gulf, Argentina, for the first time using data from onboard observers and fishing effort records. We infer expected annual mortality, evaluate the probability of exceeding conservation thresholds, and explore the importance of relevant covariates to account for broadscale differences in bycatch rates. The South American sea lion (Otaria byronia) was the most incidentally caught species (46 individuals), while only one common dolphin (Delphinus delphis) was taken. Bycatch of sea lions was primarily associated with the catch of the target species, proximity to colonies, and the identity of the target species. The maximum estimated bycatch rate was 0.12 animals/haul and 0.08 animals/tonne of target species landed, with significantly higher bycatch rates observed in the hake fleet. For the whole period, the annual bycatch mortality were below the reference points. Our findings highlight potential hotspots of marine mammal bycatch and provide valuable insights for refining future mitigation measures and enhancing conservation efforts.","PeriodicalId":18725,"journal":{"name":"Marine Mammal Science","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142206327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, vocalizations of Deraniyagala's beaked whales were recorded using drifting recording systems in the confirmed presence of this whale in the northern South China Sea (SCS) in 2021. A total of 699 qualified frequency‐modulated (FM) pulses were used to calculate frequency and duration measurements. FM pulses had a median peak frequency of 43.3 kHz and median interpulse interval (IPI) of 244.6 ms. Both the spectra measurements and clustering analysis showed the recorded clicks closely resemble the clicks of beaked whales at Palmyra Atoll (presumed to belong to Deraniyagala's beaked whale). Compared with other Ziphiidae species, interspecific differences were also observed. Distinguishing between Deraniyagala's and ginkgo‐toothed (M. ginkgodens) beaked whales with acoustic data sets seems to prove feasible. Our results also suggested that Deraniyagala's beaked whales may produce more than one subtype of FM pulses.

However, there is little information regarding the acoustic communication and behavior of Australian snubfin dolphins (Orcaella heinsohni). This study was designed to determine if call rate and type were significantly affected by the behavioral state, group size, and cohesion of snubfin dolphins in the Fitzroy River in Queensland, Australia. We found that dolphins significantly modified both call rate (calls/hour/individual) and call type among behavioral states. For example, call rates were higher when dolphins were foraging versus resting or traveling. We also found that group size and cohesion had minimal effects on call rate, but significantly affected the predicted probabilities of call type production. For example, the probability ratio of burst pulse to whistle production is estimated to be highest when groups are widespread (>10 m), indicating the potential importance of burst pulses in maintaining contact between dispersed individuals. This study presents the first comprehensive analysis of snubfin dolphin communication under natural noise conditions in relation to behavioral context, which provides a foundation to explore how anthropogenic acoustic masking and behavioral disturbances may affect these dolphins in the future.","PeriodicalId":18725,"journal":{"name":"Marine Mammal Science","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142206357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
