The δ13C range (CR) is a measure of basal resource diversity.
Finally, some practical countermeasures for sustainable utilization of resource diversity of wild landscape material flora in Mt. Lushan were given.
The δ13C range (CR) is the difference between the species with the most enriched and most depleted δ13C ratio and is a measure of basal resource diversity.
This seems to be connected to strategic conditions of high resource diversity, especially of human groups with a high or medium mobility across land.
Compared to the midstream and downstream sites, the high CR at the upstream site reflected higher degree of resource diversity and the utilization of these resources by similarly high diversity of the fish assemblage.
We herein combine the methods of game theory, evolutionary computing, and agent-based simulation to study the emergence of tag-mediated cooperation in a mobile network with resource diversity.
Consequently, large bio-geographical, chronological and climatic variations not only exposed Neanderthal populations to a wide variety of eco-geographical contexts, but also to substantial food resource diversity.
Since virtually all soil organisms are heterotrophs, and thus essentially rely on the quantity and quality of plant derived residues entering the soil subsystem [20], [27], [28], declining plant diversity, accompanied by deterioration of resource diversity, quantity and quality, is likely to impact the density, diversity and functioning of soil biota [10], [25].
Here we investigate the role of host colonizations in generating insect diversity, by testing if insect speciation rate is correlated with resource diversity.
In particular, the principle of enhancing resource diversity seemed specific to agroecology systems, whereas pollution reduction objectives were more marked in industrial ecology systems.
