Application of the USDA Forest Service National Hierarchical Framework of Ecological Units at the sub-regional level: The New England-New York example ( 1996 ) Application of the USDA Forest Service National Hierarchical Framework of ecological units at the sub-regional level: the New England–New ...
An example of an upright pyramid is the terrestrial ecosystem. It has a large base mainly consists of primary consumers, the smallertrophic levelsare located at the top. So, how do we find biomass? Biomass at a certain trophic level is calculated by multiplying the number of individuals within...
Without these "cultural keystone species," the societies they support would be completely different. An obvious example is western red-cedar (Thuja plicata) for Northwest Coast cultures of North America. Often prominent elements of local ecosystems, cultural keystone species may be used and harvested...
These indicator communities have important applications in ecological monitoring. For example, some freshwater invertebrate communities have been the basis of some ecological monitoring programs. The community structure and the species present have also been bases for the classification of rivers and lakes....
For example, if a data-driven model detects an effect of an input variable on the abundance of a certain species, a mesocosm study could be set up to manipulate this input variable to verify if it has an effect. In a second step, a mechanistic model could be calibrated to the data of...
In doing so it satisfies a research aim: to introduce a new concept that can encourage more consistent and thorough increases in functional biodiverse systems and landscapes resulting from human natural environment interactions using coffee farming as the example; by answering the question: how can a...
For example, the residents of Yucun Village in Zhejiang, where Xi put forward the concept, as early as 2003 decided to close down its limestone mines and cement factories after realizing the industry had caused severe dam...
The AEZ approach has much to offer in terms of assessing the capability of a country to feed its current and future population. It has been promoted by FAO who have applied the system in, for example, Mozambique (FAO, 1982), Bangladesh (FAO, 1988) and Kenya (FAO 1991). The Technical ...
For example, the recovery pattern of broad-leaved forests in the south region is considerably different from that of conifer forests in the northeast region, where the regrowth rate of conifer forests in the northeast region is slower and the species richness of reference forests is lower. ...
