Примери за biotic

• Geochemical observations appear to mirror palaeontological data, thus possibly relating chemical changes within the carbon cycle to biotic evolution.

• Large-scale destabilization events in hydrological structure of oceans, biotic crises, and corresponding geological records.

• We expect that over time these agroecosystems would remain with less biotic diversity (genetic, species and patch) than natural grassland ecosystems.

• This and other questions raised will need to be answered before biotic indicators or thresholds are implemented.

• According to this picture, new features collectively emerge during biotic self-organization on every level, from the internal cellular gel to the whole colony.

• The discussion of biotic function and indicators is well done but the authors draw primarily from references explicitly associated with soil quality.

• The chapter contains some novel points and raises questions that should contribute to thinking about how biotic indicators and ecotoxicology can be meaningfully applied.

• Linking species and ecosystems: different biotic assemblages cause interstream differences in organic matter.

• 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.

• 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.

• For wheat production environments, specific factors such as climate, soil, socio-economic conditions, and biotic stresses are considered.

• The characterization of organic phases, from abiotic or biotic sources, also appears to be a fundamental issue.

• Only biotic agents can respond to population density in this way, although not all such agents necessarily do so.

• In other words, as biotic pressure increases and the wetland becomes less attractive as an ecosystem, one can expect a fall in elasticity.

• The crisis of nannoconids appears to be the only global biotic event across this interval.
