Traditional Performance

Although women’s wailing at death rites in various cultures typically amplifies mortality salience, this ritual phenomenon is absent in the research literature on terror management theory (TMT). This study explored Yemenite-Jewish wailing in Israel as an example of how a traditional performance manages death anxiety in a community context. Observations of wailing events and interviews with Yemenite-Jewish wailers and mourners in Israel were analyzed to understand respondents’ perceptions of the experience of wailing as well as the anxiety-oriented psychotherapeutic expertise involved. The findings are discussed to propose an alternative outlook on the intersubjective adaptive value of death anxiety. After describing TMT’s view on the role of culture in coping with death anxiety, I consider the extent to which Yemenite-Jewish wailing is consistent with the premises of TMT.

Divergence With Gene Flow

Polymorphic chromosomal rearrangements, which can bind together hundreds of genes into single genetic loci with diverse effects, are increasingly associated with local adaptation and speciation. They may also be an important component of genetic variation within populations. We genetically and phenotypically characterized a novel segregating inversion (inv6) in the Iron Mountain (IM) population of Mimulus guttatus (yellow monkeyflower). We first identified a region of recombination suppression in three F2 mapping populations resulting from crosses among IM plants; in each case, the F1 hybrid parent was heterozygous for a homogenous derived haplotype (inv6) across markers spanning over 4.2 Mb of Linkage Group 6. Genotype-phenotype associations in the three F2 populations demonstrated negative inv6 effects on male and female fitness components. In addition, inv6 carriers suffered a ~30% loss of pollen viability in the field. Despite these costs, inv6 exists at moderate and apparently stable frequency (~7%) in the natural population, suggesting counter-balancing fitness benefits that maintain the polymorphism. Across four years of monitoring in the field, inv6 had an overall significant positive effect on the seed production (lifetime female fitness) of carriers. This benefit was particularly strong in harsh years and may be mediated (in part) by strong positive inv6 effects on flower production. These data suggest that opposing fitness effects maintain an intermediate frequency, and as a consequence, inv6 generates inbreeding depression and high genetic variance. We discuss these findings in the context of theory about the genetic basis of inbreeding depression and the role for chromosomal rearrangements in population divergence with gene flow.
