A natural, self-maintaining photoelectric cell, composed of a blue-green algal mat and bacteria as a layered ecosystem, was isolated from a shallow marine bay in Texas near Port Aransas. In daytime the open-circuit potential across the ecological membrane was about 0.43 volt.

Forests are a unique study ecosystem that can reveal global insights into the patterns and processes associated with biological invasions via their natural diversity, as well as their diversity of anthropogenic interactions. In this chapter we focus on emblematic species groups in different forest ecosystems, giving temperate and tropical examples of ...

Business Ecosystems, Platform Ecosystems und Innovation Ecosystems
Controlling, 2019In Forschung und Praxis ist immer häufiger die Rede von Ecosystems. Vorherrschend sind dabei insbesondere die Konzepte des Business Ecosystem, Platform Ecosystem und Innovation Ecosystem. Eine trennscharfe Differenzierung zwischen diesen Konzepten fehlt bisher. Ziel dieses Beitrags ist es, Definitionen von Ecosystems abzugrenzen sowie Eigenschaften und

Ecosystems and Ecosystem Services
2020This chapter identifies core principles of ecology and environmental science applicable to the nexus and discusses the tightly coupled socio-ecological systems that establish ecosystems services (ES) within the nexus. The chapter begins by outlining key ecological principles and their interdependencies, demonstrating how ecosystem services are provided

Ecosystem management is to make adaptive management strategy based on full understanding the process of composition, structure and function of ecological system, and to restore or maintain ecosystem integrity and sustainability. Forest ecosystem management attempts to maintain forest ecosystem complex process, path and the interdependent relationship ...
