LIFE TABLES OF PSEUDACYSTA PERSEAE DURING 3 DIFFERENT SEASONS WHEN COHORTS WERE EITHER EXPOSED TO OR PROTECTED FROM BIOTIC FACTORS
We focused the discussion on aphids and had each student list all abiotic and biotic factors
that may influence the population size of aphids.
Abiotic atmospheric environmental factors--including temperature, moisture, light, and wind--together with biotic factors
affect plant growth and development significantly.
The conclusion of this analysis is that purely mechanical arguments define a range of conditions, or a window, outside of which the ballooning activity cannot be physically sustained irrespective of the biotic factors
The purpose of this experiment was to investigate if these biotic factors
are responsible for the soilsickness due to CMAR.

, silver bioaccumulation.
Entomologists have realized that pathogens, particularly the mycopathogens, are influenced by a complex of variable abiotic and biotic factors
and by various management tactics that may be disruptive to natural controls.

Among the biotic factors
that might affect burrow structure would be the risk of predation.
In a series of papers, Dixon explored biotic factors
affecting aggregation in sycamore aphids (Dixon, 1966; Dixon & McKay, 1970; Dixon & Logan, 1972) but also noted occasions where exposure to weather was a main factor.
Contributing scientists review crop pathogens and the role of biotic factors
in disease development in a variety of crops and settings.
subpopulations are associated with distinct abiotic and biotic factors
, including known tularemia vectors and hosts.
Two groups of associations were identified in each river --a commonly occurring species group exhibiting strong homogenous correlation with environmental factors and a predominant group exhibiting weak correlation with environmental factors and whose abundance / composition may be defined by biotic factors
