Scientists microphones calving Arctic glacier
2020/4/10
Researchers at the Scripps Institution of Oceanography are eavesdropping on an Arctic glacier in the name of science. In a new study, scientists Oskar Glowacki and Grant Deane describe a method of mea...
SYNOPTIC OBSERVATIONS OF CALVING EVENTS IN ANTARCTICA USING SPACEBORNE IMAGES
Antarctica Calving Optical Images Rifts Icebergs
2019/2/28
Iceberg calving is the detachment of ice from ice shelves or glaciers. Although calving is a natural phenomenon, an abnormal rate of calving can be a threat to ice shelves. Some of the events were so ...
A Genome Wide Association Study on Age at First Calving Using High Density Single Nucleotide Polymorphism Chips in Hanwoo (Bos taurus coreanae)
Single Nucleotide Polymorphism Whole Genome
2016/5/17
Age at first calving is an important trait for achieving earlier reproductive performance. To detect quantitative trait loci (QTL) for reproductive traits, a genome wide association study was conducte...
The Effect of Age at First Calving and Calving Interval on Productive Life and Lifetime Profit in Korean Holsteins
Age at First Calving Calving Interval Lifetime Profit Productive Life
2016/5/12
This study was performed to estimate the effect of age at first calving and first two calving intervals on productive life and life time profit in Korean Holsteins. Reproduction data of Korean Holstei...
Mitochondrial and Nuclear Genetic Variation across Calving Lagoons in Eastern North Pacific Gray Whales (Eschrichtius robustus)
cetacean microsatellite population structure
2015/12/11
Accurate knowledge of population structure in cetaceans is critical for preserving and managing breeding habitat,
particularly when habitat is not uniformly protected. Most eastern gray whales return...
Genetic Relationship between Milk Production, Calving Ease and Days Open at First Parity in Holstein Cows
Korean Holstein Reproductive Performance Calving Ease Days Open
2016/4/14
Data containing 14,188 lactation and reproductive records of Korean Holstein cows at first parity distributed across 3,734 herd-year-season groups were analyzed to get genetic (co)variance estimates f...
Estimation of Genetic Parameters for Calving Ease by Heifers and Cows Using Multi-trait Threshold Animal Models with Bayesian Approach
Calving Ease Genetic Parameter Multivariate Threshold Model Bayesian Method
2016/4/11
Genetic parameters for birth weights (BWT), calving ease scores observed from calves born by heifers (CEH), and calving ease scores observed from calves born by cows (CEC) were estimated using Bayesia...
