The most effective monsters of horror fiction mirror ancestral dangers to exploit evolved fears. For most of human evolutionary history, we have faced threats in the domains of predation, conspecific violence, contagion, status loss, and dangerous nonliving environmental features. We thus very easily acquire fears directed toward threats from these domains. This chapter argues that the nonrandom distribution of human fears is reflected in horror, which features stimuli that mirror evolved fears, often in incarnations that are exaggerated and/or counterintuitive for increased salience, including giant spiders, supernormal monsters such as evil clowns, and physics-violating ghosts. Many monsters are also equipped with contagion cues, thus exploiting an evolved disgust mechanism. Some monsters evoke moral disgust through their violation of norms. To strengthen audiences’ emotional responses to such monsters, horror artists often provide descriptions of characters’ reactions which are mirrored by the audience through an adaptive mechanism enabling emotional contagion.

ABSTRACT Of 31 X-ray-induced and 2 spontaneous Adh null mutations selected for resistance to pentenol (Aaron 1979), 21 are deletions, including Adh and one or more neighboring loci. By contrast, none of 13 EMS-induced Adhn mutations are deletions. On average, the size of these X-ray-induced deletions is shorter than that of 12 formaldehyde-induced Adhn deletions (O'Donnell, Mandell, Krauss and Sofer 1977). Both the X-ray- and formaldehyde-induced deletions show a nonrandom distribution of break points in region 34D to 35D of chromosome arm 2L. Some of the deletions display particular genetic properties associated with one of their end points.

We studied the effects of agriculturally induced fragmentation of forests and wetlands on amphibian assemblages and their distribution in a landscape of the midwestern United States. Potential breeding pools and upland areas in 30 forest patches of various sizes and degrees of isolation were intensively sampled for amphibians during April through August 1996 and March through August 1997 in Indiana. Species presence was documented using pitfall traps, anuran vocalization surveys, and cover-board sampling for adults and minnow traps and dip nets for larvae. Amphibian, anuran, and salamander assemblages were nonrandomly distributed across the landscape. American toads (Bufo americanus) and gray treefrogs (Hyla versicolor) were ubiquitous, whereas the distributions of several other species were ordered in a predictable manner. Logistic regression was used to develop predictive models of probabilities of occurrence for species in response to forest and wetland patch and landscape variables. Occurrence of redback salamanders (Plethodon cinereus) was positively associated with the area of a forest patch. Occurrence of ranid frogs was positively associated with proximity of wetlands for three of four species, and occurrences of smallmouth salamanders (Ambystoma texanum), spring peepers (Pseudacris crucifer), and western chorus frogs (Pseudacris triseriata) were related to the degree of wetland permanency. Multiple linear regression revealed that species richness was greatest for wetlands with intermediate degrees of permanency. The observed nonrandom distribution exhibited by several amphibians suggests that they respond to landscape-level attributes. Moreover, species differed substantially in the nature of their responses to fragmentation, consistent with differences in their life history and ecology.
