Priorities for protecting ecosystem services must be identified to ensure future human well-being. Approaches to broad-scale spatial prioritization of ecosystem services are becoming increasingly popular and are a vital precursor to identifying locations where further detailed analyses of the management of ecosystem services is required (e.g., examining trade-offs among management actions). Pri...

Functional diversity is hypothesised as being beneficial for ecosystem functions, such as productivity and resistance to invasion. However, a precise definition of functional diversity, and hence a framework for its quantification, have proved elusive. We present a definition based on the analogy of the components of species diversity / richness, evenness and divergence. These concepts are appl...

Entrepreneurship ecosystem is a combination of cultural, economic, political and social elements within an area interacting with each other to entrepreneurial activity in an environment conducive. The present study aims to achieve a model for the formation of entrepreneurial ecosystem in Iran using Grounded Theory. The main basis of data collection in this theory is to conduct semi-structured i...

The employment of higher education graduates (EHEG) in Iran is not desirable. Policymakers and executives of economic programs attribute this to the oversupply and poor quality of university graduates.  On the other hand, policymakers and implementers of higher education programs attribute this to the low demand of the Iranian economy for higher education graduates. Although both arguments are ...

Global environmental change affects the sustained provision of a wide set of ecosystem services. Although the delivery of ecosystem services is strongly affected by abiotic drivers and direct land use effects, it is also modulated by the functional diversity of biological communities (the value, range, and relative abundance of functional traits in a given ecosystem). The focus of this article ...

Software platform providers are often seen as the cornerstone of their business ecosystem, where the other ecosystem players utilize the platform’s standardized components together with complementary components for making applications. These platforms are also becoming a cornerstone of the emerging Internet of Things (IoT) business ecosystem comprised of the companies who provide Internet-enabl...

The crucial role of biodiversity in the links between ecosystems and societies has been repeatedly highlighted both as source of wellbeing and as a target of human actions, but not all aspects of biodiversity are equally important to different ecosystem services. Similarly, different social actors have different perceptions of and access to ecosystem services, and therefore, they have different...
