Interchanges and movements of humpback whales in Japanese waters: Okinawa, Ogasawara, Amami, and Hokkaido, using an automated matching system.

Humpback whales in the western North Pacific are considered endangered due to their small population size and lack of information. Although previous studies have reported interchanges between regions within a population, the relationship between the geographic regions of a population in Japan is poorly understood. Using 3,532 fluke photo IDs of unique individuals obtained from four areas in Japan: Hokkaido, six IDs (2009-2019); Ogasawara, 1,477 IDs, from two organizations (1) Everlasting nature of Asia (1987-2020) and (2) Ogasawara Whale Watching Association, (1990-2020); Amami, 373 IDs (1992-1994, 2005-2016); Okinawa, 1,676 IDs (1990-2018), interchanges were analyzed.

Neuropsychological characteristics of adults with attention-deficit/hyperactivity disorder without intellectual disability.

Aims: While several studies have reported various cognitive impairments in children with attention-deficit/hyperactivity disorder, the neuropsychological profiles of adults with this disorder are understudied. Here, the intelligence and memory functions of adults with attention-deficit/hyperactivity disorder without intellectual disability were evaluated.

Methods: The Wechsler Adult Intelligence Scale-Third Edition and Wechsler Memory Scale-Revised were administered to 30 adults with attention-deficit/hyperactivity disorder whose full-scale intelligence quotients were >85.
