Secondly, sexual differences in head size could be explained by a segregation of trophic niches reducing intraspecific competition since prey size might be constrained by mouth size.
Generally, in each species, mean total dry mass per plant decreased as frequency of the species increased (intraspecific competition).
The replacement series experiments are used to study and analyze the coexistence between weeds and crops, in order to evaluate the inter and intraspecific competition among plants (Radosevich et al., 2007).
Supported theories of antler function include a display of dominance to other males, a weapon for intraspecific competition, and an ornament used by females to assess male quality (Demarais and Strickland 2011).

By contrast, with longer growth periods, during which intraspecific competition for light is increased, stem elongation may represent a significant portion of herbage accumulation (PEDREIRA et al., 2009).
Intraspecific competition in the population dynamics of Bracon hebetor (Say) (Hymenoptera: Braconidae).
In some larval anurans, intraspecific competition induces longer guts, providing a digestive advantage under limiting resources.
The selection of a favorable site for the construction of these traps is based mainly on the availability of dry and sandy soil, the availability of prey and intraspecific competition (Prado et al., 1993; Faria et al., 1994).
This work is organized as follows: in Section 2 we consider the interplay between intraspecific competition and a disease on a single species model.
On the other hand, the leaf/stem dry matter ratio in the V5 stage was lower at the highest densities in both seasons, indicating that the increase in intraspecific competition promoted lower allocation of photoassimilates in the leaves, in detriment of the stem; hence, plant density significantly alters the structure of soybean canopy.
