Effect Of Locality Recognition On Aggressive Behavior In The Red Swamp Crayfish, Procambarus Clarkii, Brett K. Muramoto, Tyler Farley

Seaver College Research And Scholarly Achievement Symposium

Climate change affects habitat globally, facilitating the expansion and rapid proliferation of invasive species which damage the newly invaded ecosystem. Intraspecific aggression among an invasive species is an important focus in ecological studies because it can contribute to their overall success as invaders. The crayfish species, Procambarus clarkii, inhabits freshwater streams in the Santa Monica Mountains (Los Angeles, CA) as an aggressive invasive predator. These invasive crayfish are well known for their highly aggressive interactions with conspecifics. It has been shown that body size, temperature, sex, and level of hunger influence their levels of aggression. However, there is a …
