For the 40 years after end of commercial whaling in 1976, humpback whale populations North Pacific Ocean exhibited a prolonged period recovery. Using mark–recapture methods on largest individual photo-identification dataset ever assembled for cetacean, we estimated annual ocean-basin-wide abundance species from 2002 through 2021. Trends estimates describe strong post-whaling era population recovery 16 875 (± 5955) to peak estimate 33 488 4455) 2012. An apparent 20% decline 2012 2021, 26 662...
The abundance of California sea lions (Zalophus californianus) (CSLs) and Guadalupe fur seals (Arctocephalus philippii townsendi) (GFSs) from the San Benito Archipelago (SBA) was determined through nine monthly surveys in 2014-2015. Assessment their foraging habits examined based on isotopic analysis pups (maternal indicators) (SIAR/SIBER-R). Environmental variability between 2014 2015 also analyzed, terms surface temperature (SST) chlorophyll (Chl-a) concentration. Both otariids reached...
ABSTRACT Individual recognition mechanisms have played a key role in odontocete ecology, maintaining social cohesion and therefore ensuring the maintenance of long‐term ties. The current study was first to identify describe stereotyped whistle contour types by both visual similarity value judgment task acoustic temporal parameters free‐ranging Risso's dolphins ( Grampus griseus ) Mexican Pacific waters Gulf California. In total, 64.1% (118) all analyzed whistles (184) were classified as...
We present an ocean-basin-scale dataset that includes tail fluke photographic identification (photo-ID) and encounter data for most living individual humpback whales (Megaptera novaeangliae) in the North Pacific Ocean. The was built through a broad collaboration combining 39 separate curated photo-ID catalogs, supplemented with community science data. Data from throughout were aggregated into 13 regions, including six breeding feeding one migratory corridor. All images compared minimal...
Abstract This study is the first baseline acoustic description of common bottlenose dolphin populations ( Tursiops truncatus ) from Revillagigedo Archipelago and identification signature whistles (SWs) in an oceanic population T. . A total 85% (199/233) recorded were classified as stereotyped subsequently (bout analysis/SIGID) categorized into one five SW types. External observers perfect agreement classifying adopted categorization. SWs represented 42% (98/233) repertoire. Overall, most...

The Guadalupe fur seal (GFS, Arctocephalus townsendi) was distributed on the islands of Baja California, Mexico, and southern United States. species intensively hunted during 19th century, in late 1920s it thought that extinct, but 1954, a few animals were located Isla Guadalupe, California. Since current status GFS population is unknown, we used counts pups collected between 1984 2013 from which still only place where reproduces, Bayesian inference to assess both trend abundance. increased...
Historically, there has been only one documented fatal killer whale (Orcinus orca) attack on a fin (Balaenoptera physalus)—from Baja California, Mexico (BC), in 2005. We compiled records of seven more recent attacks, including four from BC. Two male whales that we identified were involved, separately or together, at least the five kills off BC as they traveled with their groups length Peninsula both sides. They also involved two Bryde’s edeni) kills, and suggest might specialize large prey....

Abstract The humpback whales which breed in the Mexican Pacific represent an important fraction (~38%) of estimated population North Pacific. Despite importance waters for reproductive habits this species, little is known about ecology these whales, along continental coast Mexico. We analysed temporal variation abundance, group types, and inter- intra-annual recapture rates adjacent to Isabel Island National Park as well intra- inter-seasonal movements with Banderas Bay breeding areas....

Abstract We present an ocean-basin-scale dataset that includes tail fluke photographic identification (photo-ID) and encounter data for the majority of living individual humpback whales ( Megaptera novaeangliae ) in North Pacific Ocean. The was built through a broad collaboration combining 39 separate curated photo-ID catalogs supplemented with community science data. All available images were compared using recently developed machine learning artificial intelligence image recognition...
