NEW RESEARCH LOOKS AT GENETIC VARIATION IN A HUMAN COMMENSALIST TOAD
GENETIC VARIATION HUMAN COMMENSALIST TOAD
2016/2/22
Most species are negatively affected when humans transform natural habitats into urban areas and agricultural lands, but a few species actually benefit from these activities. These species — called hu...
Colony variation in the collective regulation of foraging by harvester ants
Colony variation harvester ants
2015/12/10
This study investigates variation in collective behavior in a natural population of colonies of the harvester ant, Pogonomyrmex
barbatus. Harvester ant colonies regulate foraging activity to adjust t...
Protection Mutualisms and the Community: Geographic Variation in an Ant-Plant Symbiosis and the Consequences for Herbivores
Ant-plant mutualism Azteca context
2015/12/10
Protection mutualisms mediate trophic interactions in many systems, but their effects
on the surrounding community are rarely studied. Ant-plant symbioses are classic
examples of protection mutual...
Birdsong variation as a source of information for migrating common yellowthroats
birdsong common yellowthroat migration social information stopover biology
2014/12/18
Social information affects the movement decisions of animals and is often an essential factor in habitat selection. Social information should be especially relevant to long-distance migrating birds th...
VCS: Tool for Visualizing Copy Number Variation and Single Nucleotide Polymorphism
Copy Number Variation Cytomap Homozygosity Single Nucleotide Polymorphism Visualization
2016/5/17
Copy number variation (CNV) or single nucleotide phlyorphism (SNP) is useful genetic resource to aid in understanding complex phenotypes or deseases susceptibility. Although thousands of CNVs and SNPs...
Genetic Variation and Phylogenetic Relationships of Indian Buffaloes of Uttar Pradesh
Buffalo Mitochondrial DNA D-loop Region Neutrality Test Phylogenetic Analysis
2016/5/12
India possesses a total buffalo population of 105 million out of which 26.1% inhabit Uttar Pradesh. The buffalo of Uttar Pradesh are described as nondescript or local buffaloes. Currently, there is no...
Swine Leukocyte Antigen-DQA Gene Variation and Its Association with Piglet Diarrhea in Large White, Landrace and Duroc
SLA DQA Gene Genetic Polymorphism Piglet Diarrhea
2016/5/12
The swine leukocyte antigen class II molecules are possibly associated with the induction of protective immunity. The study described here was to investigate the relationship between polymorphisms in ...
MHC-DQB1 Variation and Its Association with Resistance or Susceptibility to Cystic Echinococcosis in Chinese Merino Sheep
Chinese Merino Sheep MHC-DQB1 Exon 2 Genotype Cystic Echinococcosis
2016/5/11
Cystic echinococcosis (CE), one of the world’s most geographically widespread diseases, still represents a considerable economic and public health significance, although a variety of methods has been ...
Characterization of Insertional Variation of Porcine Endogenous Retroviruses in Six Different Pig Breeds
Insertional Variation Pig Breeds Porcine Endogenous Retroviruses (PERVs) Xenotransplantation
2016/5/10
Pigs may need to be exploited as xenotransplantation donors due to the shortage of human organs, tissues and cells. Porcine endogenous retroviruses (PERVs) are a significant obstacle to xenotransplant...
The effect of individual variation on the structure and function of interaction networks in harvester ants
agent-based model movement pattern network analysis
2015/12/10
Social insects exhibit coordinated behaviour without central control. Local interactions
among individuals determine their behaviour and regulate the activity of the colony.Harvester ants are recruit...
Morphological and morphometric analysis of variation in the Zhoukoudian Homo erectusbrain endocasts
Morphological morphometric Zhoukoudian Homo
2014/3/26
The six Zhoukoudian (ZKD) Locality 1Homo erectusspecimens derive from stratigraphic levels 11–3 with
a geochronological span of approximately 0.3 Ma. This paper introduces the history of the ZKD endo...

2016/4/29
There are currently five primary breeds of Chinese gamecock, the Henan, Luxi, Tulufan, Xishuangbanna and Zhangzhou. Though there is historical evidence of cockfighting in China dating as far back as 2...
Evaluation of Genetic Variation and Phylogenetic Relationship among North Indian Cattle Breeds
Cattle Genetic Variation India Microsatellite
2016/4/28
In the present study, genetic analyses of diversity and differentiation were performed on four breeds of Indian zebu cattle (Bos indicus). In total, 181 animals belonging to Ponwar, Kherigarh, Gangati...
Investigation of Deletion Variation and Methylation Patterns in the 5' LTR of Porcine Endogenous Retroviruses
Pigs Long Terminal Repeat (LTR) Porcine Endogenous Retroviruses (PERVs) Xenotransplantation
2016/4/28
The xenotransplantation of pig organs and cells can be related with a risk of transmission of infectious diseases to human. Previous findings indicate that the regulatory region of PERV for retroviral...
