15] reported that survival rate, mean body weight, mean total length and specific growth rate were stocking density dependent for C.
This also might explain the absence of relationship between proportional crop loss to Amazons and distance of neighbor depredated conspecific, which tend to be positive when density dependent seed predation occurred (Villasenor-Sanchez et al.
Among the topics are first-order chemical reaction networks, binding processes and transcription rates, density dependent population processes and the linear noise approximation, and mass action kinetics.
Hutchinson (1953) determined that at least five causal factors shape the spatial pattern of plant species: 1) environmental factors such as nutrients or light availability, 2) reproductive factors including propagule dispersal and seasonality, 3) interspecific or social factors such as territoriality, predation and competition, 4) intraspecific components such as competition and density dependent factors and 5) stochastic variation in any of these causal factors.
The experiment showed that the growth of Furcellaria lumbricalis and Coccotylus truncatus was density dependent and that the algal growth decreased with increasing densities.
It is important to understand the influence of density dependent and independent factors on macroptery because of their potential to dilute the impact of this insect on plant populations.
Specifically, fecundity-at-length variability in autumn spawning herring in the Gulf of Maine (Kelly & Stevenson, 1985), spring and autumn spawning herring in the Gulf of St Lawrence (Lambert, 1987), the Clyde spring spawning herring (Bailey & Almatar, 1989), but also in a range of other fish species (Bagenal, 1973) has been suggested and has been related to density dependent effects.
