The vocal development of the Red-crowned Crane Grus japonensis

Ornithological Science, 2007
ABSTRACT Most studies on avian vocal ontogenesis have focused on taxa exhibiting some kind of vocal learning. This study provides a detailed analysis of vocal processes through early and late ontogenesis in 17 chicks of the Red crowned Crane Grus japonensis, a species lacking vocal learning.

Microstructure of feather of red crowned crane (Grus japonensis)

Journal of Northeast Forestry University, 1995
Through scanning electron microscope, various types of feathers in various parts of red-crown crane—a kind of rare and precious bird were observed micrographically. It was shown in the result that in different type of feather, the barbules show a great variation in their morphology and structure.

Cloning, expression and antiviral bioactivity of Red-crowned Crane interferon-α

Gene, 2014
Interferon-α (IFN-α) genes have been cloned from a variety of animals, but information regarding crane IFN-α has not been reported to date. In this study, we cloned a full-length Red-crowned Crane interferon-α (crIFN-α) gene sequence consisting of a 486bp partial 5' UTR, 741bp complete ORF and 559bp partial 3' UTR.

A multiscale approach to identifying spatiotemporal pattern of habitat selection for red-crowned cranes

Science of The Total Environment, 2020
Effective conservation measures largely depend on knowledge of habitat selection of target species. Little is known about the scale characteristics and temporal rhythm of habitat selection of the endangered red-crowned crane, limiting the habitat conservation.

Voice breaking in adolescent red-crowned cranes (Grus japonensis)

Behaviour, 2010
Summary Voice breaking is a process associated with puberty of human males that also occurs in adolescence in some birds. This study reports the jump-like vocal changes occurring during voice breaking in adolescent red-crowned cranes (Grus japonensis).

Winter habitat selection of red-crowned crane (Grus japonensis)

Journal of Forestry Research, 2000
This paper studied the winter habitat selection of red-crowned cranes (Grus japonensis) in Yancheng National Natural Reserve, Jiangsu Province. There were six types of habitat used by red-crowned cranes, i.e. salt-works, aquiculture ponds, reed lands, grassy tidal lands, salting wormwood lands and wheat fields. The wheat field was a new type of habitat

Abandoned Farmlands as a Potential New Habitat for Red-crowned Cranes

2018
In Japan, whose population has begun to decline, there is a concern that abandoned and fallow farmlands will increase due to rapid population decline, and the resulting waste of national land will progress. However, if it is possible to properly manage land released from development pressure in the course of population decline, and regenerate it into a

[A wintering habitat model for red crown crane].

Ying yong sheng tai xue bao = The journal of applied ecology, 2002
A mathematical model was established based on GIS and RS to simulate and predict the habitat distribution of red crown crane(Grus japonensis) in Yancheng Biosphere Reserve, Jiangsu Province, China. The model was tested through calculating the match coefficience of observed and predicted presence/absence data, which was 72.63%, showing that the model ...

Status and Perspective of the Red-crowned Crane Based on Genetic Diversity

2018
Although the population inhabiting Hokkaido (island population) of the red-crowned crane had been reduced to near extinction at the end of the nineteenth century, the population size has recovered and continues increasing now thanks to conservation activities.

Genetic variation of major histocompatibility complex genes in the endangered red-crowned crane

Immunogenetics, 2017
Populations that have drastically decreased in the past often have low genetic variation, which may increase the risk of extinction. The genes of major histocompatibility complex (MHC) play an important role in the adaptive immune response of jawed vertebrates.
