Estimation of genetic parameters of fatty acids composition in flesh of market size common carp (Cyprinus carpio L.) and their relation to performance traits revealed that selective breeding can indirectly affect flesh quality
genetic correlations genetic improvement growth heritability slaughtering traits, supplemental feeding
2018/11/23
Fish are a rich source of omega-3 polyunsaturated fatty acids (n-3 PUFAs) and thus, they should be an integral part of human diet at least twice a week. As a result, high attention has been devoted to...
Two single nucleotide polymorphisms in the caprine GnIH gene are associated with litter size
PCR-RFLP SNPs combined genotype candidate gene
2017/6/22
Gonadotropin-inhibitory hormone (GnIH) can decrease luteinizing hormone and/or follicle-stimulating hormone levels in rat, mouse, sheep, and cattle by the direct suppression of gonadotropin-releasing ...
Body size, metabolic rate, generation time, and the molecular clock
molecular clock generation time
2015/12/17
There is increasing evidence for variation in
rates of nucleotide substitution among divergent taxonomic
groups. Here, we summarize published rate data and show a
strong relationship between substi...
Tree size frequency distributions, plant density, age and community disturbance
Allometry community ecology plant size stem diameter
2015/8/27
We show that explicit mathematical and biological relationships exist among the scaling exponents and the allometric constants (a and b, respectively) of log–log linear tree-community size frequency d...
Size-dependent species richness:trends within plant communities and across latitude
Community ecology plant size species packing species richness
2015/8/27
We examine how species richness and species-specific plant density (number of species and number of individuals per species, respectively) vary within community size frequency distributions and across...
Estimation of additive and dominance variance for litter size components in rabbits
REML analysis dominance effects family class effect
2015/7/3
Additive, dominance, and permanent environmental variance components were estimated for the number of kits born alive, number of kits born dead, and total number of kits born of a synthetic rabbit lin...
Missense mutations in exon 2 of the porcine leptin receptor gene and their associations with litter size and body weight
LEPR SNPs pigs
2015/6/8
Leptin receptor (LEPR) gene is regarded as a “candidate-gene” of production traits. The aims of this study were to detect polymorphisms of exon 2 within LEPR gene and to investigate their associations...
REMOTE SENSING OF WATER COLOR: MODEL SENSITIVITY ANALYSIS AND ESTIMATION OF PHYTOPLANKTON SIZE FRACTIONS
Sensitivity analysis Phytoplankton size
2015/1/16
Phytoplankton size classes (pico-plankton, nano-plankton, and micro-plankton) provide information about pelagic ocean ecosystem structure, and their spatiotemporal variation is crucial in understandin...
The impact of lipid-based nutrient supplement provision to pregnant women on newborn size in rural Malawi: a randomized controlled trial
lipid-based nutrient supplements home-fortification intrauterine growth restriction, pregnant women preterm birth
2018/12/20
Background: Small birth size, often associated with insufficient maternal nutrition, contributes to a large share of global child undernutrition, morbidity, and mortality. We developed a small-quantit...

Long-term population size of the North Atlantic humpback whale within the context of worldwide population structure
Effective population size Humpback whale
2015/12/11
Once hunted to the brink of extinction, humpback whales (Megaptera novaeangliae) in the North
Atlantic have recently been increasing in numbers. However, uncertain information on past abundance makes...
The roles of productivity and ecosystem size in determining food chain length in tropical terrestrial ecosystems
ecosystem size food chain length food web structure islands
2015/11/13
Many different drivers, including productivity, ecosystem size, and disturbance,
have been considered to explain natural variation in the length of food chains. Much remains
unknown about the role o...
Accurate Estimation of Effective Population Size in the Korean Dairy Cattle Based on Linkage Disequilibrium Corrected by Genomic Relationship Matrix
Linkage Disequilibrium Dairy Cattle Effective Population Size SNP
2016/5/12
Linkage disequilibrium between markers or genetic variants underlying interesting traits affects many genomic methodologies. In many genomic methodologies, the effective population size (Ne) is import...
Estimation of Effective Population Size in the Sapsaree: A Korean Native Dog (Canis familiaris)
Effective Population Size Inbreeding Rate Linkage Disequilibrium SNP Sapsaree Dog
2016/5/10
Effective population size (Ne) is an important measure to understand population structure and genetic variability in animal species. The objective of this study was to estimate Ne in Sapsaree dogs usi...
Outbreak size distributions in epidemics with multiple stages
Outbreak size distributions epidemics with multiple stages Populations and Evolution
2012/5/2
Multiple-type branching processes that model the spread of infectious diseases are investigated. In these stochastic processes, the disease goes through multiple stages before it eventually disappears...
