Hibernation clustering and its consequences for associative nest foundation in<Emphasis Type="Italic"> Polistes dominulus</Emphasis> (Hymenoptera Vespidae)

Various studies indicate that cuticular hydrocarbons (CHCs) act as cues for nestmate recognition in paper wasps and other social insects. A recent study showed that associative nest foundation in Polistes dominulus is mainly performed by foundresses coming from the same locality. In the present study, we induced future foundresses of P. dominulus collected in two different localities to hibernate in the laboratory in aggregates of individuals from the same or different localities. After 2 months of hibernation, foundresses from different localities but from the same experimental cluster did not show any preference to associate, at the time of nest foundation, with individuals coming from the same original locality. The cuticular chemical profiles of individuals from the mixed hibernation clusters were quite similar and significantly different from those of individuals which hibernated with other foundresses from the same locality. These findings suggest that, in this species, mechanisms other than nestmate chemical recognition play a major role in the spring association of gynes during the foundation of a new nest.Communicated by R.F.A.

Social Capital in Biodiversity Conservation and Management

Abstract:  The knowledge and values of local communities are now being acknowledged as valuable for biodiversity conservation. Relationships of trust, reciprocity and exchange, common rules, norms and sanctions, and connectedness in groups are what make up social capital, which is a necessary resource for shaping individual action to achieve positive biodiversity outcomes. Agricultural and rural conservation programs address biodiversity at three levels: agrobiodiversity on farms, nearby nature in landscapes, and protected areas. Recent initiatives that have sought to build social capital have shown that rural people can improve their understanding of biodiversity and agroecological relationships at the same time as they develop new social rules, norms, and institutions. This process of social learning helps new ideas to spread and can lead to positive biodiversity outcomes over large areas. New ideas spread more rapidly where there is high social capital. There remain many practical and policy difficulties, however, not least regarding the need to invest in social capital formation and the many unresolved questions of how the state views communities empowered to make their own decisions. Nonetheless, attention to the value of social relations, in the form of trust, reciprocal arrangements, locally developed rules, norms and sanctions, and emergent institutions, has clearly been shown to deliver a biodiversity dividend in many contexts. This suggests a need to blend both the biological and social elements of conservation.

Two facets of conscientiousness and the knowledge sharing dilemmas in the workplace: Contrasting moderating functions of supervisor support and coworker support

This study adopts self‐ and other‐centered approaches to explain how the two facets of conscientiousness (i.e., dutifulness and achievement striving) distinctly resolve knowledge sharing dilemmas among employees. It also explores how the critical social surroundings of employees (i.e., supervisor support and coworker support) neutralize or activate the effects of dutifulness and achievement striving on knowledge‐sharing behavior. Our analysis of the data collected from 150 employee–supervisor dyads corroborates that the other‐centered facet of conscientiousness (dutifulness) is positively related to knowledge‐sharing behavior, whereas the self‐centered facet (achievement striving) is negatively related to the same behavior. The analysis also affirms that the positive effect of dutifulness and the negative effect of achievement striving on knowledge sharing are strengthened when supervisor support is low and coworker support is high. This study offers theoretical and practical implications relevant to knowledge management in organizations, distinct roles of facet‐specific personalities toward knowledge sharing, and contrasting personality–situation interactions by situation strength and trait activation in shaping employee behavior.     

Steel sharpens steel: A review of multilevel competition and competitiveness in organizations

Competition between individuals permeates people's lives as they strive for limited resources, services, and status. However, research on competition and competitiveness in organizations is limited despite its relevance to relational dynamics (e.g., rivalry), individual differences (e.g., traits and gender), social factors (e.g., competitive climate), and organizational outcomes (e.g., work performance and unethical behavior). In this article, we propose a multilevel model of competition and competitiveness that includes the individual, the group, and the situation. By providing a holistic overview of research across a broad array of disciplines, we organize the field and create a usable framework to advance knowledge of competition and competitiveness. In doing so, we identify what we know, what we still need to discover, and provide direction for future research. The article closes with an assessment of methods and measures used in studying competition. In conclusion, this review establishes a multilevel and integrative structure that incorporates individual and team competitiveness with competitive situations that prompt competitive processes and important organizational outcomes.
