This paper presents a scale developed to classify organizations through cluster analysis as being exploiters, explores, ambidextrous or with no defined orientation. The theoretical framework helps identify that the concepts associated with exploration and exploitation may be classified into six practical eywords:
Extrafloral nectar (EFN) plays an important role as plant indirect defence through the attraction of defending ants. Like all rewards produced in the context of a mutualism, however, EFN is in danger of being exploited by non-ant consumers that do not defend the plant against herbivores. Here we asked whether plants, by investing more in EFN, can improve their indirect defence, or rather increa...
This study presents a strategy for environmental management that aims to enhance efforts restore threatened ecosystems. We review the exploratory system and classify stakeholders driving forces behind nature exploitation. Based on successful cases, we propose practical modifications adding economic value restoring collapsed ecosystems, resulting in development of blue management. Blue isolates ...
Two studies were conducted to identify the incidence (Study 1) and characteristics (Study 2) of juvenile prostitution cases known to law enforcement agencies in the United States. Study 1 revealed a national estimate of 1,450 arrests or detentions (95% confidence interval [CI]: 1,287-1,614) in cases involving juvenile prostitution during a 1-year period. In Study 2, exploratory data were collec...
A common empirical observation in mutualistic interactions is the persistence of variation in partner quality and, in particular, the persistence of exploitative phenotypes. For mutualisms between hosts and symbionts, most mutualism theory assumes that exploiters always impose fitness costs on their host. We exposed legume hosts to mutualistic (nitrogen-fixing) and exploitative (non-nitrogen-fi...
