- The Influence of Sex and Phenotype on Shoaling Decisions in Zebrafish. Snekser, Jennifer L.; Ruhl, Nathan; Bauer, Kristoffer; McRobert, Scott P. // International Journal of Comparative Psychology;2010, Vol. 23 Issue 2, p70
Fish typically choose shoalmates with similar phenotypic characteristics to themselves, thus creating shoals for which predators have difficulty identifying and attacking one specific individual. And while shoaling should provide similar anti-predator benefits to both males and females, the two...
- The Behavioral and Pharmacological Actions of NMDA Receptor Antagonism are Conserved in Zebrafish Larvae. John Chen; Patel, Roshni; Friedman, Theodore C.; Jones, Kevin S. // International Journal of Comparative Psychology;2010, Vol. 23 Issue 2, p82
Dizocilpine maleate (MK-801) is one of several NMDA receptor antagonists that is widely used to pharmacologically model the symptoms of psychosis and schizophrenia in animals. MK-801 elicits behaviors in adult zebrafish (Danio rerio) that are phenotypically consistent with behaviors observed in...
- Heritability of Boldness and Aggressiveness in the Zebrafish. Ariyomo, Tolulope; Carter, Mauricio; Watt, Penelope // Behavior Genetics;Mar2013, Vol. 43 Issue 2, p161
Behavioural traits that are consistent over time and in different contexts are often referred to as personality traits. These traits influence fitness because they play a major role in foraging, reproduction and survival, and so it is assumed that they have little or no additive genetic variance...
- Socially-Central Zebrafish Influence Group Behavior More than Those on the Social Periphery. Vital, Cuauhcihuatl; Martins, Emilia P. // PLoS ONE;Jan2013, Vol. 8 Issue 1, Special section p1
Certain individuals are more effective than others at using individual experience to impact group behavior. Here, we tested whether pre-training of zebrafish that are at the focal central of social group dynamics ("Key" fish) has a stronger positive impact on group performance than does...
- A zebra in the classroom. Leake, Devin; Morvillo, Nancy // American Biology Teacher;Jan1998, Vol. 60 Issue 1, p32
Presents information relating to the care and breeding of zebrafish by biology students. Instructions for breeding of the fish; Development of the zebrafish embryos; Steps for regeneration process of the fish.
- The cyclops mutation blocks specification of the floor plate of the zebrafish central nervous... Hatta, K.; Kimmel, C.B. // Nature;3/28/1991, Vol. 350 Issue 6316, p339
Analyzes mutations in the zebrafish. Reports that in wild-type embryos the floor plate develops as a simply organized single cell row, but that its development fails in embryos bearing the newly discovered zygotic lethal cyclops mutation, `cyc'-1(b16).
- A homeobox gene essential for zebrafish notochord development. Talbot, William S.; Trevarrow, Bill // Nature;11/9/1995, Vol. 378 Issue 6553, p150
Describes the phenotype of floating head mutant zebrafish embryos. Absence of notochord; Display of abnormalities in mesoderm and CNS derivatives; Molecular characterization of the floating head gene.
- Fast Skeletal Muscle-Specific Expression of a Zebrafish Myosin Light Chain 2 Gene and Characterization of Its Promoter by Direct Injection into Skeletal Muscle. Xu, Yanfei; He, Jiangyan; Tian, Ho Lian; Chan, Chiew Hua; Liao, Ji; Yan, Tie; Lam, Toong Jin; Gong, Zhiyuan // DNA & Cell Biology;Jan1999, Vol. 18 Issue 1, p85
A zebrafish myosin light chain 2 cDNA clone was isolated and characterized. Sequence analysis of the clone revealed a high homology with the mammalian and avian genes encoding the fast skeletal muscle isoform, MLC2f. In situ hybridization and Northern blot hybridization analyses indicated that...
- Microarray analysis and quantitative real-time PCR validation of gene expression during auditory hair cell regeneration in zebrafish (Danio rerio). Schuck, Julie B.; Chia-Hui Lin; Penberthy, William T.; Xiaohong Li; Cooper, Nigel G. F.; Smith, Michael E. // BMC Bioinformatics;2009 Supplement 7, Vol. 10, p1
An abstract of a study related to the quantitative real-time polymerase chain reaction (PCR) validation and microarray analysis of gene expression during auditory hair cell regeneration in zebrafish, which was conducted by Julie B. Schuck and colleagues, is presented.
