Want to Hookup?: Sex Differences in Short Term Mate Attraction Tactics

While a great deal of psychological research has been conducted on sex-specific mate choice preferences, relatively little attention has been directed toward how heterosexual men and women solicit short-term sexual partners, and which acts are perceived to be the most effective. The present research relied on an act nomination methodology with the goal of determining which actions are used by men and women to solicit a short-term “hook-up” partner (study 1) and then determine which of these actions are perceived as most effective by men and women (study 2). Using sexual strategy theory, we hypothesized that actions that suggest sexual access would be nominated most often by women whereas actions that suggest a willingness to commit were expected to be nominated most often by men. Additionally, men and women were predicted to rate actions by men that suggest a willingness to commit as most effective and actions by women that suggest sexual access as most effective. The results were consistent with these hypotheses. These findings are discussed in the context of both short- and long-term mating strategies and mate solicitation. The relationship between motivation, sexual strategies, and sexual behavior are examined, along with the need for research on the hookup tactics and motivations of self-identifying gay, lesbian, and bisexual individuals

Development of Gene Expression Markers of Acute Heat-Light Stress in Reef-Building Corals of the Genus Porites

Coral reefs are declining worldwide due to increased incidence of climate-induced coral bleaching, which will have widespread biodiversity and economic impacts. A simple method to measure the sub-bleaching level of heat-light stress experienced by corals would greatly inform reef management practices by making it possible to assess the distribution of bleaching risks among individual reef sites. Gene expression analysis based on quantitative PCR (qPCR) can be used as a diagnostic tool to determine coral condition in situ. We evaluated the expression of 13 candidate genes during heat-light stress in a common Caribbean coral Porites astreoides, and observed strong and consistent changes in gene expression in two independent experiments. Furthermore, we found that the apparent return to baseline expression levels during a recovery phase was rapid, despite visible signs of colony bleaching. We show that the response to acute heat-light stress in P. astreoides can be monitored by measuring the difference in expression of only two genes: Hsp16 and actin. We demonstrate that this assay discriminates between corals sampled from two field sites experiencing different temperatures. We also show that the assay is applicable to an Indo-Pacific congener, P. lobata, and therefore could potentially be used to diagnose acute heat-light stress on coral reefs worldwide

Location-Specific Responses to Thermal Stress in Larvae of the Reef-Building Coral Montastraea faveolata

The potential to adapt to a changing climate depends in part upon the standing genetic variation present in wild populations. In corals, the dispersive larval phase is particularly vulnerable to the effects of environmental stress. Larval survival and response to stress during dispersal and settlement will play a key role in the persistence of coral populations.To test the hypothesis that larval transcription profiles reflect location-specific responses to thermal stress, symbiont-free gametes from three to four colonies of the scleractinian coral Montastraea faveolata were collected from Florida and Mexico, fertilized, and raised under mean and elevated (up 1 to 2 degrees C above summer mean) temperatures. These locations have been shown to exchange larvae frequently enough to prevent significant differentiation of neutral loci. Differences among 1,310 unigenes were simultaneously characterized using custom cDNA microarrays, allowing investigation of gene expression patterns among larvae generated from wild populations under stress. Results show both conserved and location-specific variation in key processes including apoptosis, cell structuring, adhesion and development, energy and protein metabolism, and response to stress, in embryos of a reef-building coral.These results provide first insights into location-specific variation in gene expression in the face of gene flow, and support the hypothesis that coral host genomes may house adaptive potential needed to deal with changing environmental conditions
