Where Deer Roam: Chronic Yet Acute Site Exposures Preclude Ecological Risk Assessment

Global positioning system (GPS) technology has made possible the detailed tracking of the spatial movements of wildlife. Using GPS tracking collars placed on female white‐tailed deer (Odocoileus virginianus) over a protracted period, we illustrate that this species is spatially irrelevant for consideration in ecological risk assessments (ERAs) for commonly assessed contaminated sites. Specifically, deer movements do not allow for a sufficiency of chemical exposures to occur such that toxicological endpoints would be triggered. Deer are spatially irrelevant not only because their home ranges and overall utilized areas dwarf prototypical hazardous waste sites. They are also inappropriate for assessment because they only minimally contact reasonably sized preferred locations, this while demonstrating a confounding high degree of site affinity for them. Our spatial movements analysis suggests that deer introduce the ERA novelty of a species displaying elements of both chronic and acute site exposure. We further suggest that other large commonly assessed high‐profile mammals could also be found to be spatially irrelevant for ERAs were they to submit to the GPS tracking and subsequent data analysis we performed for the deer. Recognizing that certain receptors need not be considered in ERAs can help to simplify the ERA process.     

Lesbian and bisexual women's judgments of the attractiveness of different body types

Two studies were conducted using the Internet with 209 and 141 women respectively who reported themselves as being lesbian or bisexual, but not heterosexual. Women were presented with 8 figures in which weight (slender or heavy), waist‐to‐hip ratio (0.7 or 1.0), and breast size (small or large) were varied independently. Participants rated figures on a 20‐point scale for attractiveness, healthiness, femininity, kindness, and desirability for both short‐term and long‐term relationships. These ratings were summed to give a total preference score as a factor analysis showed that all ratings loaded positively on one factor. In the second study, women were also asked to rate themselves on the degree to which they were gender‐conforming or gender‐nonconforming. In both studies, participants preferred the heavy figure with the 0.7 waist‐to‐hip ratio and large breasts. The same figure with small breasts was the next most preferred. In the second study, there was no difference between gender‐conforming and gender‐nonconforming women in preference scores. We believe that a preference on the part of nonheterosexual women for heavy figures may reflect more comfort with heavier body weight as well as a rejection of what may be seen as an inappropriate societal fixation on excessive thinness.
