Effects of Momordica charantia Saponins on In vitro Ruminal Fermentation and Microbial Population
Momordica charantia Saponin In vitro Fermentation Microbial Population Roughage
2016/5/20
This study was conducted to investigate the effects of Momordica charantia saponin (MCS) on ruminal fermentation of maize stover and abundance of selected microbial populations in vitro. Five levels o...
Microsatellite Analysis of the Genetic Diversity and Population Structure in Dairy Goats in Thailand
Microsatellite Genetic Diversity Dairy Goat
2016/5/19
The genetic relationships between different populations and breeds of exotic dairy goats in Thailand were studied using 12 microsatellite markers. Blood samples were obtained from 211 goats from Depar...

Spanish missions Native American population collapse climate
2016/2/22
New interdisciplinary research in the Southwest United States has resolved long-standing debates on the timing and magnitude of American Indian population collapse in the region.The severe and rapid c...
Population structure of the black tiger prawn, Penaeus monodon, among western Indian Ocean and western Paci®c populations
tiger prawn Penaeus monodon
2015/12/17
We examined the population structure of the
black tiger prawn, Penaeus monodon Fabricius, 1798, in
the Indo-West Paci®c by analyzing the geographic distribution of elongation factor 1-alpha int...
Contrasting Population Structure from Nuclear Intron Sequences and mtDNA of Humpback Whales
Nuclear Intron Sequences mtDNA
2015/12/17
Powerful analyses of population structure require information from multiple genetic loci. To help develop a
molecular toolbox for obtaining this information, we have designed universal oligonucleoti...
Pre-Whaling Genetic Diversity and Population Ecology in Eastern Pacific Gray Whales: Insights from Ancient DNA and Stable Isotopes
Population Ecology Pre-Whaling Genetic Diversity
2015/12/11
Commercial whaling decimated many whale populations, including the eastern Pacific gray whale, but little is known about
how population dynamics or ecology differed prior to these removals. Of partic...
The simple fool’s guide to population genomics via RNA-Seq: an introduction to high-throughput sequencing data analysis
bioinformatics de novo assembly gene expression
2015/12/11
High-throughput sequencing technologies are currently revolutionizing the field of biology and medicine, yet bioinformatic challenges in analysing very large data sets have slowed the adoption o...
A Method for Detecting Population Genetic Structure in Diverse, High Gene-Flow Species
Diverse High Gene-Flow Species
2015/12/11
Detecting small amounts of genetic subdivision across geographic space remains a persistent challenge. Often a failure to
detect genetic structure is mistaken for evidence of panmixia, when more powe...
SNP genotyping and population genomics from expressed sequences – current advances and future possibilities
SNP genotyping population genomics
2015/12/11
With the rapid increase in production of genetic data from new sequencing technologies,
a myriad of new ways to study genomic patterns in nonmodel organisms are currently
possible. Because genome as...
The intertwined population biology of two Amazonian myrmecophytes and their symbiotic ants
ant–plant interactions Cordia nodosa demography
2015/12/10
A major question in ecology is: how do mutualisms between species affect
population dynamics? For four years, we monitored populations of two Amazonian
myrmecophytes, Cordia nodosa and Duroia hirsut...

Branch diffusion process of single particle particle
2015/9/25
We investigate the long-time and long-range behavior of branching diffusion processes (starting with a single particle) in two different situations: when the
branching potential has compact support a...
