Coreopsis tinctoria appears able to use spatial gaps to overcome some of the negative effects of interspecific competition (Elliott and Van Auken, 2014).
To our knowledge, however, few studies have explicitly tested both individual-based and the effect of distribution type on group-based interspecific competition in invasive plant species.
In the tree-hole/tiger model, the largest sources of uncertainty in [R.sub.0] were the survival rate of tree-hole mosquitoes, the biting rate of tree-hole mosquitoes, and interspecific competition of tiger and tree-hole mosquitoes.
Interspecific competition for traps set on tree branches had a negligible (if any) negative effect on the capture rates of the common dormouse during our study.

In this study intra- and interspecific competition between the component crops in a leek/celery intercropping system were analyzed in multiple field experiments.
Notonectids combined with hydrometrids yielded a higher larvae and pupae consumption rates suggesting that there is an interspecific competition on the prey population.
(2007) observed a different behavior to the one observed in the present study in consortium planting of Eucalyptus grandis and leguminous trees, where the fine root density of all leguminous was always smaller in relation to the eucalyptus at the soil superior layers, suggesting a strong interspecific competition at these layers.
Thus, the addition of interspecific competition (without predators) induced leopard frogs to develop a relatively small increase in mouth size and wood frogs to develop a relatively large increase in mouth size and a slightly longer tail.
