Tajikistan is a hotspot of plant and animal species diversity and endemism andis important for the conservation of biodiversity on a global scale. The country is located ata biological crossroads. Species from Central and Northern Europe, Central Asia, theMiddle East, and North Africa mingle here with endemics found nowhere else. Therichness of Tajikistan‘s biodiversity shows up at the genetic,...

The concept of business ecosystems is a new, powerful metaphor that steps forward the movement towards symbiotic and co-evolutionary business networks. The literature describes business ecosystems as economic communities comprised of a number of business entities that are closely related the one to the other with symbiotic relationships; as a result, they constantly interact and seek to co-oper...

What factors limit ecosystem evolution? Like human economies, ecosystems are arenas where agents compete for locally limiting resources. Like economies, but unlike genes, ecosystems are not units of selection. In both economies and ecosystems, productivity, diversity of occupations or species and intensity of competition presuppose interdependence among many different agents. In both, competiti...

Resulting from the technological revolution from the last decades, we observed many software startup ecosystems emerging around the globe. Having tech entrepreneurs as their main agents, some ecosystems exist for more than 50 years, while others are newly born. This difference in terms of evolution and maturity makes the task of comparing different tech hubs a challenge. Moreover, nascent ecosy...

Context: Software ecosystems are increasingly popular for their economic, strategic, and technical advantages. Application platforms such as Android or iOS allow users to highly customize a system by selecting desired functionality from a large variety of assets. This customization is achieved using variability mechanisms. Objective: Variability mechanisms are well-researched in the context of ...

Abstract We evaluated how three widths of buffer zones on greater than or equal to 100-ha wetlands (240, 300, and 390 m) rivers (10, 20, 30 would help meet watershed conservation goals in the Upper Peninsula Michigan, USA, whether doing so also protect each predominant types terrestrial natural communities across landscape. The use (even narrowest assessed) around riparian met exceeded targets ...

The species in ecosystems are mutually interacting and self sustainable stable for a certain period. Stability and dynamics are crucial for understanding the structure and the function of ecosystems. We developed a potential and flux landscape theory of ecosystems to address these issues. We show that the driving force of the ecological dynamics can be decomposed to the gradient of the potentia...

The notion of software ecosystems has been popular both in research and industry for more than a decade, but how software ecosystems are created still remains unclear. This becomes more of a challenge if one examines the “creation” of ecosystems that have high probability in surviving in the future, i.e. with respect to ecosystem health. In this paper, we focus on the creation of software ecosy...
