Therefore hemp plant spacing is dependent on the type of production of the fiber, seed, or CBD to which the plantation is devoted. In agreement with Amaducci et al. (2002), for fiber production, the hemp is planted at high-density stands to encourage stalk elongation and reduced branching,...
Population Regulation in an Ecosystem With regard to the population size of a species and what factors may affect them, two factors have been defined. They are the density-dependent factors and the density-independent factors. Find out the differences between the two in this tutorial. Know how ...
(p<0.0001). This could be explained by the fact that fluorometry incorporates a procedure to correct for stray fluorescent light (age-dependent lens fluorescence in the eye and spurious fluorescence in the optics)[11], whereas non-confocal AF imaging does not. Furthermore, the reference ...

and age by sex interaction were tested. Tissue thickness, layer and region were built into a multivariate analysis of variance as covariates with eight dependent variables: short stubby, long stubby, thin, short mushroom, long mushroom, branched, atypical and filopodia densities and age and sex fi...

The optimal and critical limits of soil BD are dependent on soil texture, particle size, management practices, and organic matter content (Reichert et al., 2009). A BD of less than or equal to 1.3 g cm−3 is good, between 1.3 and 1.55 g cm−3 is fair, and greater than 1.8 g ...
we review the literature on larval density-dependent effects on fitness of non-social holometabolous insects. First, we provide a functional definition of density to navigate the terminology in the literature. We then classify the biological levels upon which larval density-dependent effects can be ...
