Size-asymmetric competition

Webb17 aug. 2024 · These analyses serve to address four objectives: (1) to determine whether competition is symmetric or asymmetric and whether it is size- or density-dependent; (2) to quantify the extent to which potential growth and competition functions vary among stands; (3) to test whether this between-stand variation can be explained by the age, size … Webb5 maj 2024 · We added size-dependent consumption of shared resources to a parameterized bioenergetics model to predict a priori the growth, parasite production, …

Webbcompetitive asymmetry in a uniform spatial pattern. Gates’s model accounted for observed changes over time in the skewness of distribution of diameters in Pinus ra-diata plantations when competition was size asymmetric. Miller and Weiner (1989) investigated the effects of spatial pattern, density, and size asymmetry on size variation in WebbThe size asymmetry of competition is reflected in the rules for dividing up the overlapping areas. Theoretical plant populations were grown in random and in perfectly uniform spatial patterns at four densities under size-asymmetric and size-symmetric competition.

Webb14 dec. 2024 · Strong competition interactions between neighbouring trees that cause size hierarchies (unequal-sized neighbouring) often leads to asymmetric competition, which was defined as larger-sized trees obtaining a disproportionate share of resources (for their relative size) and suppressing the growth of smaller ones [ 42, 43 ].

WebbNeighbouring plants compete for the resources in areas they overlap. The effective area of a plant, A c, is calculated as the area it covers minus that part of the area lost to neighbours, which is determined by the amount of overlap and the degree of size asymmetry of competition (Weiner et al. 2001).
