Species In The Study
Name the invasive fish species in the paper.
What is rainbow trout? (Oncorhynchus mykiss)
This suggests that introduced species that fill unique ecological roles not present in recipient communities should have the largest impacts.
What is the Invasion Theory?
This suggests invasive species can affect ecosystems beyond their ____.
What is habitat?
When a top predator affects many levels of the food web, like invasive rainbow trout leading to more algae.
What is a trophic cascade?
This structure was used to experimentally reduce terrestrial insect input into the stream.
What is a mesh greenhouse cover?
Name the native fish species in the paper.
What is the Dolly varden charr? (Salvelinus malma)
Name the two leading agents of global environmental change.
What are habitat alteration and biotic invasions?
This is the main reason invasive species impacts are often unpredictable.
What are indirect effects?
Name the phrase to describe when two ecosystems, like streams and forests, that are connected by energy flow.
What are cross-ecosystem connections?
This increased due to reduced grazing pressure.
What is periphyton biomass?
Invasive rainbow trout triggered a trophic cascade that increased algae and reduced these riparian forest predators by 65%.
What are riparian-specialist spiders?
In the paper, it illustrates through the term "reciprocal prey subsidies" that ____ and ____ are linked.
What are forests and streams?
This idea explains why streams and forests should not be studied separately.
What is ecosystem connectivity?
This term describes energy moving from streams to land, such as insects supporting spider populations.
What is resource subsidy?
The mechanism that triggered the trophic cascade was not direct predation, but it was this.
What is the interaction modification indirect effect?
