More importantly, this emphasis on preserving or restoring historical locations of species largely ignores the more important issue of an introduction's potential compatibility with the existing biotic community
or climatic conditions.
Also recorded was the biotic community
present (Brown and Lowe, 1994), the presence and abundance of woody plant species, presence of cacti in the immediate vicinity, presence of herbaceous ground cover and, later, the approximate distance of each animal flushed when disturbed by the vehicle or person hiking.
The fly fisher is introduced to the sport and finds some connection that spurs them to continue; nature presents its facts in the form of knowledge on hydrology, entomology, and other complexities that lead the fly fisher to learn about the web of connections in an aquatic ecosystem; experience and observation begins to open up the fly fisher to the message that environments are qualitatively important and witnessing the effects of human activity upon the biotic community
gives the fly fisher the reasons to act in the environment's interest (which is so often unknowingly in human interest); and, ultimately, the conclusion rests in the hands of the potential environmental advocate who is either converted as a steward of the environment or is held back or persuaded by other interests.
They become an integral part of the place where they live, a contributing member of the biotic community
The even-more severe limits constraining exchange of information and exchange of needs among the members of the biotic community
likewise prevent its moral character from being robustly democratic.
Leopold, writing in the 1940s, needed to extend human ethics to embrace the "integrity, stability, and beauty of the biotic community
," which he saw as a positive and necessary evolution of ethics.
Altered biotic community
composition and habitat conditions of a coastal bay associated with progressive eutrophication signal increasing ecosystem disturbance and impairment that must be tracked in order to implement effective remedial actions and circumvent the decline in human use of estuarine resources and amenities.
There is a trend towards increased numbers of new pathogens entering populations of historically healthy animals causing catastrophic results to the biotic community
Professor Leopold also wrote: "A thing is right when it tends to preserve the integrity, stability, and beauty of a biotic community
Wilson's description is a nice addendum to Aldo Leopold's seminal definition of a Land ethic published over half a century ago in A Sand County Almanac And Sketches Here and There: "A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community
A thing is right," he contends, "when it tends to preserve the integrity, stability, and beauty of the biotic community
In Sand County Almanac he wrote, "A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community
4) Do several listed members of a shared biotic community
rely on protection and/or restoration of their ecosystem to reach recovery?
This index was developed to assess a stream's biological integrity by examining the structure and health of the biotic community
