The Yangtze River dolphin or baiji ( Lipotes vexillifer ), an obligate freshwater odontocete known only from the middle-lower system and neighbouring Qiantang in eastern China, has long been recognized as one of world's rarest most threatened mammal species. status not investigated since late 1990s, when surviving population was estimated to be low 13 individuals. An intensive six-week multi-vessel visual acoustic survey carried out November–December 2006, covering entire historical range...
Abstract No global synthesis of the status baleen whales has been published since 2008 IUCN Red List assessments. Many populations remain at low numbers from historical commercial whaling, which had ceased for all but a few by 1989. Fishing gear entanglement and ship strikes are most severe current threats. The acute long‐term effects anthropogenic noise cumulative multiple stressors concern poorly understood. looming consequences climate change ocean acidification difficult to characterize....
North Pacific right whales (Eubalaena japonica) were extensively exploited in the 19th century, and their recovery was further retarded (severely so eastern population) by illegal Soviet catches 20th primarily 1960s. Monthly plots of whale sightings from both centuries are provided, using data summarised Scarff (1991, charts Matthew Fontaine Maury) Brownell et al. (2001), respectively.

ABSTRACT Bottlenose dolphins Tursiops truncatus are amongst the best‐known cetaceans. In Mediterranean Sea, however, modern field studies of cetaceans did not start until late 1980s. have been studied only in relatively small portions basin, and wide areas remain largely unexplored. This paper reviews ecology, behaviour, interactions with fisheries conservation status bottlenose dolphins, identifies threats likely to affected them historical recent times. Whilst intentional killing was...
ABSTRACT The significance of killer whale Orcinus orca predation on baleen whales (Mysticeti) has been a topic considerable discussion and debate in recent years. Discourse constrained by poor understanding predator‐prey dynamics, including the relative vulnerability different mysticete species age classes to how these prey animals avoid predation. Here we provide an overview analysis predatory interactions between mysticetes, with emphasis patterns antipredator responses. Responses advances...
The recent loss of Arctic sea ice provides humans unprecedented access to the region. Marine mammals rely on sound as a primary sensory modality, and noise associated with increasing human activities offshore can interfere vital life functions. Many coastal communities marine for food cultural identity, subsistence hunters have expressed strong concerns that underwater from negatively affects both animals hunting success. Federal regulations require scientists oil gas operators acquire...
Abstract Place‐based conservation can be an effective tool for addressing threats to marine mammals, but this approach presents many challenges, such as the dilemma of whether aim protection at appropriately large scales or through networks smaller protected areas, and how address socio‐economic conditions human societies whose welfare may conflict with mammal survival. Protecting places conserve mammals started about 50 years ago, when first parks reserves were established protect critical...
Motivated by the need to estimate abundance of marine mammal populations inform conservation assessments, especially relating fishery bycatch, this paper provides background on estimation and reviews various methods available for pinnipeds, cetaceans sirenians. We first give an “entry-level” introduction estimation, including fundamental concepts importance recognizing sources bias obtaining a measure precision. Each primary mammals is then described, data collection analysis, common...
To understand the scope and scale of loss biodiversity, tools are required that can be applied in a standardized manner to all species globally, spanning realms from land open ocean. We used data International Union for Conservation Nature Red List provide synthesis conservation status extinction risk cetaceans. One 4 cetacean (26% 92 species) was threatened with (i.e., critically endangered, or vulnerable) 11% were near threatened. Ten percent deficient, we predicted 2-3 these may also The...
The movements of individual humpback whales (Megaptera novaeangliae) can be tracked by matching photographs the distinctive markings on ventral sides their tail flukes. During winter-spring seasons 1990, 1991, 1995, 1996, 1999, 2000, 2001 and 2002 a total 42 humpbacks were identified fluke from waters Cape Verde Islands. These compared with taken elsewhere in North Atlantic. One match was made whale previously photographed Denmark Strait off Iceland, providing first direct evidence link...
The best-known present-day wintering areas for the North Atlantic population of humpback whales (Megaptera novaeangliae) are in northern West Indies, notably off island Hispaniola. However, it is known that nineteenth century American whalers hunted humpbacks Windward Islands (primarily from Guadeloupe southwards), along coast Trinidad, Gulf Paria and westwards Venezuelan coast. To investigate historical distribution occurrence whales, data were extracted whaling logbooks journals covering...
ABSTRACT 1. The recent decline in the Mediterranean population of short‐beaked common dolphins Delphinus delphis has been subject scientific controversy and political indifference. Research on these animals very limited there no large‐scale, systematic effort to assess monitor their abundance distribution. consequent lack data prevented a good understanding historical ongoing trends. 2. Nonetheless, literature osteological collections confirm that were widespread abundant much Sea until late...
ABSTRACT The vaquita Phocoena sinus is a small porpoise that endemic to the northern Gulf of California, Mexico. It most critically endangered marine cetacean in world. precise estimate global abundance based on 1997 survey 567 (95% CI 177–1073). Vaquitas mainly live north 30°45′N and west 114°20′W. Their ‘core area’ consists about 2235 km 2 centred around Rocas Consag, 40 east San Felipe, Baja California. Genetic analyses population simulations suggest has always been rare, its extreme loss...
Many severely depleted populations of baleen whales (Mysticeti) have exhibited clear signs recovery whereas there are few examples in toothed (Odontoceti). We hypothesize that this difference is due, at least part, to social and behavioural factors. Clearly, a part the lack resilience exploitation explained by odontocete life history. However, an additional factor may be highly nature many odontocetes which survival reproductive success depend on: (a) cohesion organization, (b) mutual...
