Mitochondrial genome of the Neophocaena asiaeorientalis asiaeorientalis (Phocaenidae: Neophocaena)

Mitochondrial DNA Part A, 2015
Yangtze finless porpoise, Neophocaena asiaeorientalis asiaeorientalis, is a cetacea animal which has been reclassified as a Critically Endangered species by IUCN in 2013. In this study, we determined the complete mitochondrial genome of N. a. asiaeorientalis for use in future phylogenetic analyses. The complete mitochondrial genome of N.

Evoked-potential audiogram variability in a group of wild Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis)

Journal of Comparative Physiology A, 2020
Hearing is considered the primary sensory modality of cetaceans and enables their vital life functions. Information on the hearing sensitivity variability within a species obtained in a biologically relevant wild context is fundamental to evaluating potential noise impact and population-relevant management.

Behavioral laterality in Yangtze finless porpoises ( Neophocaena asiaeorientalis asiaeorientalis )

Behavioural Processes, 2017
The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is a critically endangered species with less than 1000 individuals expected to be left in the wild. While many studies have been conducted on laterality among several cetacean species, no studies investigating the Yangtze finless porpoise have been conducted.

Accelerating population decline of Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis)

Biological Conservation, 2012
The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is now the only cetacean species in the Yangtze River following the probable extinction of the baiji (Lipotes vexillifer). However, population abundance estimates and genetic diversity studies both indicate that the porpoise population is declining and may also become extinct in

Assembly and characterization of the MHC class I region of the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis)

Immunogenetics, 2015
The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis; YFP) is the sole freshwater subspecies of N. asiaeorientalis and is now critically endangered. Major histocompatibility complex (MHC) is a family of highly polymorphic genes that play an important immunological role in antigen presentation in the vertebrates. Currently, however,

Isolation of Robinsoniella peoriensis from the fecal material of the endangered Yangtze finless porpoise, Neophocaena asiaeorientalis asiaeorientalis

Anaerobe, 2013
The aim of this study was to determine the causative agent of diarrhea in an endangered Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis). From the fecal material collected from this porpoise Robinsoniella peoriensis was isolated.

Trace elements accumulation in the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) – A threat to the endangered freshwater cetacean

Science of The Total Environment, 2019
As a freshwater cetacean with a population of only approximately 1000 individuals, the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is threatened by water pollution. However, studies of contaminants accumulated in the Yangtze finless porpoise remain limited.

Underwater noise pollution in China’s Yangtze River critically endangers Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis)

Environmental Pollution, 2020
Underwater sound plays an important role in some critical life functions of many aquatic animals. Underwater noise pollution has received relatively more attention in ocean systems. However, little attention has been paid to freshwater systems, such as the Yangtze River which is the habitat of critically endangered Yangtze finless porpoises ...

Respiratory pattern of captive Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis)

Journal of Ethology, 2006
Cetacean respiration usually happen in bouts. The most widely applied quantitative method used to analyze the structure of these bouts is the log(e)-survivorship analysis, based on the assumption that the respiratory intervals are distributed as negative exponentials.

Ultrastructure of the Spermatozoa of the Yangtze Finless Porpoise (Neophocaena phocaenoides asiaeorientalis)

Anatomia, Histologia, Embryologia, 2009
SummarySemen sample was collected from two captive adult Yangtze finless porpoises (Neophocaena phocaenoides asiaeorientalis) during physical examination. One individual was aged about 9 years with body length 143 cm (total length) and body weight 46.1 kg in 2003. The age of the other was unknown and its body length was 147 cm and body weight was 43 kg
