Although the concept of ecosystem sustainability has a long-term focus, it is often viewed from a static system perspective. Because most ecosystems are dynamic, we explore sustainability assessments from three additional perspectives: resilient systems; systems where tipping points occur; and systems subject to episodic resetting. Whereas foundations of ecosystem resilience originated in ecolo...

The possibility of application ERS-2 SAR for monitoring of Russian European tundra ecosystem components was investigated. The synergetic using of SAR with Landsat data can be widely used for investigation and mapping of tundra vegetation, soils, for the ecosystem monitoring of anthropogenic effects.

This paper investigates an ecosystem based business model in a smart grid infrastructure and the potential of value capture in a highly complex macro infrastructure such as a smart grid. It proposes an alternative perspective in studying the smart grid business ecosystem to support infrastructural challenges, such as the interoperability of business components for a smart grid. So far, little r...

1. Our goal was to quantify short-term phosphorus (P) partitioning and identify the ecosystem components important to P cycling in wetland ecosystems. To do this, we added P radiotracer to oligotrophic, P-limited Everglades marshes. PO4 was added to the water column in six 1-m enclosed mesocosms located in long-hydroperiod marshes of Shark River Slough, Everglades National Park. Ecosystem compo...

urmia lake and its surroundng wetlands have been severely affected by recent droughts (1998–2003) and a considerable decrease in inflow has affected lake ecosystem components. integrated ecosystem-based management is a useful managing tool for the wise use and biodiversity conservation of wetlands. in the process of developing an integrated ecosystem-based management model for urmia lake, the i...

We examined the potential effects of spatial heterogeneity and its development on the distribution, abundance, and functioning of nitrogen fixing and non-fixing components of a model ecosystem. CAECO, a spatially explicit individual based model approach, simulated the interactions between nitrogen fluxes and plant species community dynamics. Self-organized spatial patterns of nitrogen concentra...

Large terrestrial carnivores are important ecological components and prominent flagship species, but are often extinction prone owing to a combination of biological traits and high levels of human persecution. This study combines phylogenetic and functional diversity evaluations of global and continental large carnivore assemblages to provide a framework for conservation prioritization both bet...

All terrestrial ecosystems consist of aboveground and belowground components that interact to influence community- and ecosystem-level processes and properties. Here we show how these components are closely interlinked at the community level, reinforced by a greater degree of specificity between plants and soil organisms than has been previously supposed. As such, aboveground and belowground co...

biodiversity/biological diversity Species, genetic, and ecosystem diversity in an area, sometimes including associated abiotic components such as landscape features, drainage systems, and climate. diversity indices Measures that describe the different components of biodiversity, such as species richness (alpha diversity), beta and gamma diversity, endemicity, and higher taxon richness. ecosyste...
