Examples of invader

• In this model, invasion success is quantified in terms of the biomass of the invader.

• It is a common observation that simple, disturbed, human habitats are more readily invaded by insects and other invaders than complex, undisturbed, natural habitats.

• However, these extraterrestrial invaders of suburbia have breached humanity's ultimate boundary, that between itself and the universe.

• For example, resources are shared with competitors, so competitors indirectly decrease invader growth.

• When invaders penetrated the area, both as raiders and traders, there was a dual process.

• When the territory boundary is breached, males confront the invader with species-typical aggressive displays and threats.

• Yet not all sections of the population were united in opposition to the invaders.

• Some parasites can also directly reduce the abundance of an invader's competitors.
