Studies of "behavioral syndromes" in different populations and species animals can be used to shed light on the underlying mechanisms evolution. For example, some personality syndromes suggest existence an hormonal link, whereas other relationships between boldness aggression appear result similar selective pressures. Here, we 1 wild-derived 2 laboratory strains zebrafish (Danio rerio) examine among 5 behavioral measures: shoaling, activity level, predator approaches, latency feed after a...
Summary Androgenetic doubled haploid progeny produced from a cross between the Oregon State University and Arlee clonal rainbow trout ( Oncorhynchus mykiss ) lines, used for previous published map, were to update map with addition of more amplified fragment length polymorphic (AFLP) markers, microsatellites, type I allozyme markers. We have added than 900 bringing total number 1359 genetic markers sex phenotype including 799 Eco RI AFLPs, 174 Pst 226 72 VNTR, 38 SINE 29 known genes, 12...
The transcription factor DeltaFosB accumulates and persists in brain response to chronic stimulation. This accumulation after exposure drugs of abuse has been demonstrated previously by Western blot most dramatically striatal regions, including dorsal striatum (caudate/putamen) nucleus accumbens. In the present study, we used immunohistochemistry define with greater anatomical precision induction throughout rodent drug treatment. We also extended previous research involving cocaine,...
Little is known about the genetics controlling rate of embryonic development in salmonids, despite fact that this trait plays an important role life history wild and cultured stocks. We investigated by performing analysis quantitative loci (QTL) on two families androgenetically derived doubled haploid rainbow trout produced from a hybrid clonal lines with divergent rates. A total 170 individuals were genotyped at 222 marker [219 amplified fragment length polymorphism (AFLP) markers, 2...
We used microarray and quantitative real-time PCR (qRT-PCR) analyses in adult female zebrafish ( Danio rerio) to identify metabolic pathways regulated by starvation the liver brain. The transcriptome of whole brain showed little response 21 days starvation. Only agouti-related protein 1 agrp1) significantly responded, with increased expression brains starved fish. In contrast, a 21-day period downregulated 466 upregulated 108 transcripts liver, indicating an overall decrease activity,...
ABSTRACT Teleost fish regenerate their retinas after damage, in contrast to mammals. In zebrafish subjected an extensive ouabain‐induced lesion that destroys all neurons and spares Müller glia, functional recovery restoration of normal optic nerve head (ONH) diameter take place at 100 days postinjury. Subsequently, regenerated overproduce cells the retinal ganglion cell (RGC) layer, ONH becomes enlarged. Here, we test hypothesis a selective injury, which photoreceptors results faster fewer...
Youths with conduct disorder extract an inordinate amount of time and money from the U.S. judicial system taxpayers, yet studies pertaining to this population have been few. This study was undertaken examine co-occurrence personality disorders in a group incarcerated children adolescents raise issue possibility antisocial persons under age 18 years.One hundred juvenile offenders aged 11-17 years were randomly selected then interviewed Diagnostic Interview for Children Adolescents--Revised...
The process of domestication in fish is fundamentally important to conservation efforts because the extensive use hatcheries mitigate population declines. Research into genetic changes associated with many endangered species impeded by a lack genomic tools, long generation times, and large space requirements. study genetics could therefore benefit from introduction model system. In this paper, we document behavioral growth rate differences observed between domesticated laboratory strain...
We tested whether boldness is associated with attenuation of the physiological stress response in behaviorally selected lines zebrafish Danio rerio. measured three component behaviors boldness: cortisol levels under control and stressed conditions, growth rate, expression key genes linked to hypothalamic-pituitary-interrenal axis brain. Surprisingly, bold animals did not differ from shy respect levels. However, significant differences between these glucocorticoid receptors that regulate...
Conditions during fetal development influence health and disease in adulthood, especially critical windows of organogenesis. Fetal exposure to the endocrine disrupting chemical, bisphenol A (BPA) affects multiple organ systems rodents monkeys. However, effects BPA on cardiac have not been assessed. With evidence that maternal is transplacentally delivered developing fetus, it becomes imperative examine physiological consequences gestational primate development. Herein, we evaluate daily,...
Abstract Background Domesticated animal populations often show profound reductions in predator avoidance and fear-related behavior compared to wild populations. These are remarkably consistent have been observed a diverse array of taxa including fish, birds, mammals. Experiments conducted common environments indicate that these behavioral differences genetic basis. In this study, we quantified between domesticated zebrafish strains used microarray analysis identify genes may be associated...
We have cloned a second insulin gene in zebrafish and studied temporal spatial expression of two genes. Zebrafish insulin-a (insa) -b (insb) mRNAs are derived from different DNA contigs on chromosomes 5 14, respectively, representing Real-time PCR studies suggest that insa is maternal also postzygotic transcript. was observed at 1 h postfertilization (hpf) rapidly degraded by 6 12 hpf but induced 24 (i.e., after pancreas formation). Expression levels were approximately 220-fold higher than...
Abstract Until recently, an enormous effort was needed to apply genomic tools ecological investigations, especially when striving uncover the functional mechanisms of phenotypic plasticity and genetic basis evolutionary adaptation within natural populations. This present study aimed develop a resource for organism ideally suited ecology research. Over 760 unique DNA fragments containing microsatellite loci were isolated characterized from Daphnia provide more than 500 molecular markers...
Behavioral management of risk, in which organisms must balance the requirements obtaining food resources with risk predation, has been considerable interest to ethologists for many years. Although numerous experiments have shown that animals alter their foraging behavior depending on levels perceived and demand nutrients, few considered role genetic variation trade-off between these variables. We performed a study four zebrafish (Danio rerio (Hamilton, 1822)) strains test whether this...
In studies of consistent individual differences (personality) along the bold-shy continuum, a pattern behavioral correlations frequently emerges: individuals towards bold end continuum are more likely to utilize risky habitat, approach potential predators, and feed under conditions. Here, we address hypothesis that observed phenotypic among component behaviors result underlying genetic (quantitative architecture). We used replicated three-generation pedigree zebrafish (Danio rerio) study...
Zebrafish (Danio rerio) have emerged as a popular model for studying the pharmacology and behavior of anxiety. While there been numerous studies documenting anxiolytic anxiogenic effects common drugs in zebrafish, many do not report or test behavioral differences between sexes. Previous indicated that males females differ their baseline level In this study, we sex interaction with fluoxetine nicotine. We exposed fish to system water (control), 10 mg/L fluoxetine, 1 nicotine three minutes...
