Climate explains population divergence in drought-induced plasticity of functional traits and gene expression in a South African Protea

Abstract: Long term environmental variation often drives local adaptation and leads to trait differentiation across populations. Additionally, when traits change in an environment-dependent way through phenotypic plasticity, the genetic variation underlying plasticity will also be under selection. These processes could create a landscape of differentiation across populations in traits and their plasticity. Here, we studied drought responses in seedlings of a shrub species from the Cape Floristic Region, the common sugarbush (Protea repens). We measured morphological and physiological traits, and sequenced whole transcriptomes in 8 populations that represent both the climatic and the geographic distribution of this species. We found that there is substantial variation in how populations respond to drought, but we also observed common patterns such as reduced leaf size and leaf thickness, and upregulation of stress- and down-regulation of growth-related gene groups. Both high environmental heterogeneity and milder source site climates were associated with higher plasticity in various traits and co-expression gene networks. Associations between traits, trait plasticity, gene networks and the source site climate suggests that temperature may play a bigger role in shaping these patterns when compared to precipitation, in line with recent changes in the region due to climate change. We also found that traits respond to climatic variation in an environment dependent manner: some associations between traits and climate were apparent only under certain growing conditions. Together, our results uncover common responses of P. repens populations to drought, and climatic drivers of population differentiation in functional traits, gene expression and their plasticity.

Lucille: Cross Cultural Counseling With Older Adult Populations

Abstract: The percentage of the population in the United States comprised of older adults (65+), sometimes referred to as Baby Boomers (birth year 1946 – 1964) and the Silent Generation (birth year 1925 – 1945), is steadily on the rise. This population is often overlooked and has a unique subset of issues when it comes to counseling competencies. Layered multicultural competencies affecting these individuals include race, gender, sexual orientation, religion, and ageism. Counseling concerns related to age include but are not limited to loss of autonomy, loss of physical ability, loss of loved ones, and changing definition of self. From an existential therapeutic background blended with Cognitive Behavioral Therapy (CBT) interventions, the author reviews the case study of Lucille with a focus on therapeutic intervention and Multicultural and Social Justice Counseling Competencies (MSJCCs).

Uses and Effects of MySpace among Christian Teens and Young Adult

Abstract: In 2008, MySpace was one of the world’s top Internet destinations. Behind only Google and Yahoo in Internet traffic in America, it was the most popular social networking site (SNS) with some 300,000 profiles being added daily. Although MySpace would soon be supplanted in the SNS world by the likes of Facebook and Twitter, it still has over 50 million unique users each month and over 300,000 video views monthly. Research performed during the period of its height in popularity is still valuable not only for historical perspective, but also for what it teaches about the habits of SNS users today. This study of the uses and effects of MySpace among Christian teens and young adults (n = 242), computes four composite variables: a Positive Effects Variable (PEV), a Negative Effects Variable (NEV), an Expressing Faith Variable (EFV), and a Friends and Family Variable (FFV), in order to consider interaction effects among various categories such as, age, gender, church attendance frequency, MySpace use experience and frequency, number of MySpace friends, etc. The results provide important insights for those who wish to maintain and promote a group identity through SNS platforms.

Overwintering of white shrimp in estuarine impoundments in louisiana3

Abstract: White shrimp (Penaeus setiferus) stocked into a 7.7 ha, closedoff, oil pipeline canal survived winter water temperatures as low as 9 C. Shrimp averaged 4 g in October, 1972, and 26 8 by May, 1973. Salinity averaged 23.0 ppt.
