What are some "danger zone" ecosystems?
The area in and around Yellowstone National Park represents one of the largest relatively intact temperate-zone ecosystems on the planet.
However, the composition and strength of linkages between salmon and these PSC members vary so much in space and time that most appear unsuitable as generally useful indicators of the potential magnitude of salmon-dependent, MDN-transport from aquatic to riparian-zone ecosystems.
In the current paper laser activated camera systems, salmon carcass manipulation and deoxyribonucleic acid (DNA) analysis of hair samples were employed to (1) identify large vertebrate members of the PSC of riparian zone ecosystems and (2) quantify the strength of linkages of these PSC vertebrates to spatial and temporal changes in salmon abundance.
However, investigations into the endophyte status of invasive plants in arid zone ecosystems, the secondary metabolites produced and the antimicrobial activities of these metabolites are limited.
As a result of four decades of extraction-based land practices in the region, the SJLSBC was established to protect Northern Zone ecosystems, promote sustainable practices while still allowing land to be privately owned, and to provide a continuous stretch of forest between Costa Rica and Nicaragua.

Trees are less common in this arid zone ecosystem [ 6, 7].
The twilight zone ecosystem contains a diverse range of prokaryotes and eukaryotes.
This is the first study to describe the isolation and antibacterial activities of endophytic fungi from O. dillenii, an invasive plant from an arid zone ecosystem.
