The outcome of mutualistic interactions depends on the costs and benefits for each of the partners, which have been shown to be both context‐ and species‐dependent. This phenomenon is seen in the interactions between plants in the genus Silene and moths in the genus Hadena.
In this study, the interaction between native North American species Silene stellata and Hadena ectypa is examined to understand the factors that influence female H. ectypa oviposition decisions, a behaviour that influences both herbivore and plant fitness.
While most studies focus on oviposition preference between different host plant species, here it is shown that for a specialist pollinating seed predator, oviposition preference occurs within a host species (and even within a plant) based upon individual flower age and pollination status.
Female H. ectypa preferentially visited and oviposited on young flowers and flowers that were unpollinated. Larvae also preferred to feed on young fruits.
Female H. ectypa oviposition choice was consistent with optimal oviposition theory, as oviposition preference was correlated with larval feeding preference and not just adult visitation preference.
Students’ achievement is positively correlated with teacher encouragement. This article focuses on the use of Adlerian group play therapy principles and techniques to foster teacher resiliency and reduce burnout. A review of the factors impacting teacher burnout, a description of the practice of Adlerian group play therapy, and the benefits of play techniques with adults will be provided. A case applying Adlerian group play therapy principles and techniques with teachers for the purpose of combating teacher burnout and fostering resilience will be presented and discussed, including considerations for implementation within a school setting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
