The crisis of nannoconids appears to be the only global biotic event across this interval.
In other words, as biotic pressure increases and the wetland becomes less attractive as an ecosystem, one can expect a fall in elasticity.
Only biotic agents can respond to population density in this way, although not all such agents necessarily do so.
The characterization of organic phases, from abiotic or biotic sources, also appears to be a fundamental issue.
For wheat production environments, specific factors such as climate, soil, socio-economic conditions, and biotic stresses are considered.
These chapters also include hands-on collecting tips and give a sense of the logistic challenges and ingenuity that imbue biotic inventories in remote tropical areas.
We point out that parasites, in particular, have the most linkages to life-history parameters either directly or through indirect routes via other biotic interactions.
Linking species and ecosystems: different biotic assemblages cause interstream differences in organic matter.
