Evaluating management effectiveness of marine protected areas in regulating fishing pressure on spotted seal (Phoca largha) habitats

Global Ecology and Conservation
Marine protected areas (MPAs) have become effective tools for biodiversity conservation and fishery management. They provide a safe environment for the breeding and development of fish populations and endangered species.

Molecular analysis of parapoxvirus from a spotted seal Phoca largha in Japan [PDF]

Diseases of Aquatic Organisms, 2011
A spotted seal Phoca largha with nodular and scab lesions on the whole body was brought to an aquarium in Nagoya, Japan. We extracted DNA from the lesions and used the polymerase chain reaction (PCR) method for detecting orthopoxvirus and parapoxvirus DNA. Parapoxvirus but not orthopoxvirus DNA was detected.

The Utilization of Space by Juvenile Spotted Seals (Phoca largha) from Peter the Great Bay (East Sea/Sea of Japan) Throughout the Year [PDF]

Animals
Spotted seals (Phoca largha) exhibit an unusual ecological feature within the population of Peter the Great Bay (PGB). Following the breeding and molting seasons, one group performs long-distance foraging migrations, whereas another group remains in the ...

A synthesized dataset of Pacific Arctic marine mammal occurrences (1860-2024)NSF Arctic Data Center [PDF]

Data in Brief
Data on marine mammals in the Pacific Arctic region are limited, variably collected over time and by multiple sources. Therefore, collation and synthesis of previously collected data, such as the dataset presented here, make these data more useful to ...

Distribution of the Spotted Seal, Phoca largha, along the Coast of Baekryongdo [PDF]

Han'guk Susan Hakhoe Chi = Bulletin of the Korean Fisheries Society, 2010
This study investigated the distribution of spotted seals, Phoca largha, inhabiting the coast of Baekryongdo. Monitoring of spotted seals in Baekryongdo was conducted between June 2006 and November 2008, using a 5-ton fishing vessel 1hour before low tide. The monthly maximum number of observed seals was 274 in September 2006, 139 in September 2007, and

Spring haul-out behavior of seals in the Bering and Chukchi Seas: implications for abundance estimation [PDF]

PeerJ
Ice-associated seals rely on sea ice for a variety of activities, including pupping, breeding, molting, and resting. In the Arctic, many of these activities occur in spring (April through June) as sea ice begins to melt and retreat northward.

Enhancing shear strength predictions of UHPC beams through hybrid machine learning approaches [PDF]

Scientific Reports
Ultra-high-performance concrete (UHPC) beam shear strength prediction is a complicated process due to the involvement of numerous parameters. The accuracy needed for precise predictions is frequently lacking in current empirical equations and traditional
