Parental effects in plantago lanceolata l. i.: a growth chamber experiment to examine pre- and postzygotic temperature effects.

Abstract: In spite of the potential evolutionary importance of parental effects, many aspects of these effects remain inadequately explained. This paper explores both their causes and potential consequences for the evolution of life-history traits in plants. In a growth chamber experiment, I manipulated the pre- and postzygotic temperatures of both parents of controlled crosses of Plantago lanceolata. All offspring traits were affected by parental temperature. On average, low parental temperature increased seed weight, reduced germination and offspring growth rate, and accelerated onset of reproduction by 7%, 50%, 5%, and 47%, respectively, when compared to the effects of high parental temperature. Both pre- and postzygotic parental temperatures (i.e., prior to fertilization vs. during fertilization and seed set, respectively) influenced offspring traits but not always in the same direction. In all cases, however, the postzygotic effect was stronger. The prezygotic effects were more often transmitted paternally than maternally. Growth and onset of reproduction were influenced both directly by parental temperature as well as indirectly via the effects of parental temperature on seed weight and germination. Significant interactions between parental genotypes and prezygotic temperature treatment (G × E interactions) show that genotypes differ in their intergenerational responses to temperature with respect to germination and growth. The data suggest that temperature is involved in both genetically based and environmentally induced parental effects and that parental temperature may accelerate the rate of evolutionary change in flowering time in natural populations of P. lanceolata. The environmentally induced temperature effects, as mediated through G × (prezygotic) E interactions are not likely to affect the rate or direction of evolutionary change in the traits examined because postzygotic temperature effects greatly exceed prezygotic effects.

Biological, behavioral, and relational levels of resilience in the context of risk for early childhood behavior problems.

Abstract: Longitudinal growth patterns of internalizing and externalizing behavior problems were examined in a community sample of 441 children across the ages of 2 to 5 using hierarchical linear modeling. Contextual risk was measured using five indicators (socioeconomic status, marital status, number of siblings, parent stress, parent psychopathology), and three levels of child resilience (biological, behavioral, and relational) were also assessed. Results indicate that a general pattern of decline in both types of behavior problems was observed for the entire sample across time, although considerable individual variability in this pattern was observed. Children's externalizing and internalizing behavior at age 5 was predicted by the level of risk at age 2. All three child resilience factors were also predictive of externalizing and internalizing behaviors at age 5. In the prediction of the slope of problem behavior over time, risk status interacted with both temperamental fearlessness and a mutually responsive orientation with the mother to predict the decline in externalizing and internalizing problem behavior. Results underscore the complex interactions of risk and multiple levels of resilience that are implicated in the maintenance of problem behavior over time. They highlight the importance of considering whether expected resilience factors operate similarly across different levels of risk.

Developmental Career Assessment and Counseling: The C-DAC Model.

Abstract: The C-DAC model seeks to implement current development theory and to use innovative assessment measures together with improved counseling methods to improve vocational and life career counseling. At this stage, the project pays more attention to assessment, partly because if one is to counsel with career maturity in mind, one must understand the developmental status of the counselee. In career counseling, facts as well as feelings are important. Therefore, in this article the authors deal with the assessment of career development in detail, treating interests (measured by the Strong) and expressed preferences as basic status data to be viewed in the light of career maturity, the salience of life roles, and the values sought in life as moderator variables. The instruments are described and their use shown in a sample profile for assessment and checking by the reader in another readily available published source.

An Update on Non-CB1, Non-CB2 Cannabinoid Related G-Protein-Coupled Receptors.

Abstract: The endocannabinoid system (ECS) has been shown to be of great importance in the regulation of numerous physiological and pathological processes. To date, two Class A G-protein-coupled receptors (GPCRs) have been discovered and validated as the main therapeutic targets of this system: the cannabinoid receptor type 1 (CB1), which is the most abundant neuromodulatory receptor in the brain, and the cannabinoid receptor type 2 (CB2), predominantly found in the immune system among other organs and tissues. Endogenous cannabinoid receptor ligands (endocannabinoids) and the enzymes involved in their synthesis, cell uptake, and degradation have also been identified as part of the ECS. However, its complex pharmacology suggests that other GPCRs may also play physiologically relevant roles in this therapeutically promising system. In the last years, GPCRs such as GPR18 and GPR55 have emerged as possible missing members of the cannabinoid family. This categorization still stimulates strong debate due to the...
