avipoxvirus infection in two captive japanese cormorants (phalacrocorax capillatus).	cormorant fishing is a traditional japanese fishing method using captive japanese cormorants (phalacrocorax capillatus). between june and july 2017, an avian pox outbreak was reported in captive cormorant populations throughout several distant cities in japan. we examined the lesions obtained from two such affected cormorants, which were raised in distant cities. the affected cormorants were grossly characterized by the development of cutaneous nodules around the base of the beak. histopathologi ...	2020	32378644
ontogeny of surface texture of limb bones in modern aquatic birds and applicability of textural ageing.	despite its importance in various disciplines, a general method to assess ontogenetic ages of skeletal and fossil specimens has been lacking for birds. although the textural ageing method was formulated to assess relative ontogenetic ages of specimens from inspection of bone surface textures, the exact correspondence of surface textures to ontogenetic stages has not yet been clear. in this study, bone surface textures of six major limb bones (humerus, ulna, carpometacarpus, femur, tibiotarsus, a ...	2018	29195009
global monitoring of persistent organic pollutants (pops) using seabird preen gland oil.	situated at high positions on marine food webs, seabirds accumulate high concentrations of persistent organic pollutants (pops), such as polychlorinated biphenyls (pcbs), dichlorodiphenyltrichloroethane and its metabolites (ddts), and hexachlorocyclohexanes (hchs). our previous studies proposed the usefulness of seabirds preen gland oil as a nondestructive biomonitoring tool. the present study applied this approach to 154 adult birds of 24 species collected from 11 locations during 2005-2016 to ...	2018	30232531
the first isolation of aspergillus allahabadii from a cormorant with pulmonary aspergillosis.	in this study, we report the first isolation of aspergillus allahabadii from a japanese cormorant with pulmonary aspergillosis. we performed molecular identification and antifungal susceptibility testing with the e-test. a 7-month-old male cormorant died because of uric acid deposition secondary to dehydration. whitish nodular lesions were present on the caudal thoracic air sac in the right thoracic cavity. histopathology revealed multifocal pyogranulomatous necrotic lesions with numerous fungal ...	2016	27904055
polymorphism of dopamine receptor d4 exon i corresponding region in chicken.	in stockbreeding, there are indications that behavioral traits of livestock have an effect on breeding and production. if the variation in individual behavior is related to that in neurotransmitter-related genes such as in humans, it would be possible to breed pedigrees composed of individuals having behavioral traits that are useful to production and breeding using selection based on genotypes. in this study, we investigated the exon i region of dopamine receptor d4 (drd4), in which variation i ...	2004	15459452
intersexual differences in the diving behaviour of foraging subantarctic cormorant (phalacrocorax albiventer) and japanese cormorant (p. filamentosus).	cormorants feed by feet-propelled diving. how cormorants optimize foraging is of a particular interest in relation to the understanding of the feeding strategies of diving birds, as well as within the debate about cormorants' impact on sustainable resources. using microdata loggers that recorded diving depth, we investigated the foraging strategy of males and females of subantarctic cormorants, which inhabit cold regions, and of japanese cormorants, which live in the northern temperate zone. for ...	1999	10488429
