For this reasons, the proposed research project will, using an experimental system with the model species Heterandria formosa that combines individual level and long term population level manipulations, investigate the consequences of and mechanisms behind body size specific, density dependent
life history traits linked to behavioural types.
2] with variability in sampling density dependent
on proximity to known and expected mineralization and structures.
The experiment showed that the growth of Furcellaria lumbricalis and Coccotylus truncatus was density dependent
and that the algal growth decreased with increasing densities.
growth of the tropical abalone Huliotis asinina in cage culture.
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

For studying the compacts density dependent
on compacting pressure was used powder mixture Ancorsteel 1000 B with granulations presented in table 2 and Zn stearat 1%.
At lung volumes characterized by predominantly laminar flow patterns, which are generally in the airways having cartilaginous support, the expiratory flow is gas density dependent
resulting in higher flows using lower density gas.
A general model for density dependent
death rate equation can be defined in the form
