In order to make students aware of complex ecological interactions, the lesson sequence addressed three major units: (1) designing research and collecting and interpreting data (2) how adaptations in predators and prey shape their interactions, and (3) the effects of abiotic and biotic factors
on aphid populations.
Likewise, defining the aforementioned biotic factors
influencing reproductive success for the Houston toad are a logical extension of this study.
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.

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.
Interdependence of Life examines the interactions between organisms and the environments in which they liveEarth spheres, ecosystems, abiotic factors, biotic factors
, populations characteristics, limiting factors, and carrying capacityas well as species relationships.
