  1. Natural genetic variation in complex mating behaviors of male Drosophila melanogaster.

    Behavior Genetics 38(4):424 (2008) PMID 18369720

    Mating behavior, including courtship and copulation, is a main component of male fitness, especially in species with no parental care. Variation in this behavior can thus be a target for mate choice and sexual selection, and can lead to evolution. The fruit fly, Drosophila melanogaster, has well...
  2. Sexual isolation and mating propensity among allopatric Drosophila mettleri populations.

    Behavior Genetics 38(4):437 (2008) PMID 18561017

    Drosophila mettleri is found in deserts of North America breeding in soil soaked by the juices of necrotic cacti. Saguaro (Carnegiea gigantea) and cardón (Pachycereus pringlei) are the usual host cacti in Mexico and Arizona, while prickly pear (Opuntia spp.) is used by an isolated population on ...
  3. The nature of nurture: a genomewide association scan for family chaos.

    Behavior Genetics 38(4):361 (2008) PMID 18360741 PMCID PMC2480594

    Widely used measures of the environment, especially the family environment of children, show genetic influence in dozens of twin and adoption studies. This phenomenon is known as gene-environment correlation in which genetically driven influences of individuals affect their environments. We cond...
  4. Gene-environment correlation and interaction in peer effects on adolescent alcohol and tobacco use.

    Behavior Genetics 38(4):339 (2008) PMID 18368474 PMCID PMC2898558

    Peer relationships are commonly thought to be critical for adolescent socialization, including the development of negative health behaviors such as alcohol and tobacco use. The interplay between genetic liability and peer influences on the development of adolescent alcohol and tobacco use was ex...
  5. Behavioural analysis of congenic mouse strains confirms stress-responsive Loci on chromosomes 1 and 12.

    Behavior Genetics 38(4):407 (2008) PMID 18379869

    The way in which animals respond to stressful environments correlates with anxiety-related behaviour. To begin identifying the genetic factors that influence anxiety, we have studied the stress-responsiveness of inbred mouse strains using a modified form of the open field activity test (OFA), te...
  6. Deletion of glucose transporter GLUT8 in mice increases locomotor activity.

    Behavior Genetics 38(4):396 (2008) PMID 18461434 PMCID PMC2480596

    Transport of glucose into neuronal cells is predominantly mediated by the glucose transporters GLUT1 and GLUT3. In addition, GLUT8 is expressed in some regions of the brain. By in situ hybridization we detected GLUT8-mRNA in hippocampus, thalamus, and cortex. However, its cellular and physiologi...
  7. Gene-environment interaction in adults' IQ scores: measures of past and present environment.

    Behavior Genetics 38(4):348 (2008) PMID 18535898 PMCID PMC2480605

    Gene-environment interaction was studied in a sample of young (mean age 26 years, N = 385) and older (mean age 49 years, N = 370) adult males and females. Full scale IQ scores (FSIQ) were analyzed using biometric models in which additive genetic (A), common environmental (C), and unique environm...
  8. Genetic mapping of vocalization to a series of increasing acute footshocks using B6.A consomic and B6.D2 congenic mouse strains.

    Behavior Genetics 38(4):417 (2008) PMID 18535899 PMCID PMC2504763

    Footshock response is used to study a variety of biological functions in mammals including drug self-administration, learning and memory and nociception. However, the genetics underlying variability in footshock sensitivity are not well understood. In the current studies, a panel of B6.A consomi...
  9. Human expression variation in the mu-opioid receptor is paralleled in rhesus macaque.

    Behavior Genetics 38(4):390 (2008) PMID 18379868

    The mu-opioid receptor is a key component in many neurobiological systems including those affecting perceptions of pain and pleasure. In humans and non-human primate model systems, genetic variation in the receptor has been associated with numerous behavioral and physiological traits. In humans,...
  10. A general test for gene-environment interaction in sib pair-based association analysis of quantitative traits.

    Behavior Genetics 38(4):372 (2008) PMID 18389355 PMCID PMC2480607

    Several association studies support the hypothesis that genetic variants can modify the influence of environmental factors on behavioral outcomes, i.e., G x E interaction. The case-control design used in these studies is powerful, but population stratification with respect to allele frequencies ...
