Revegetation Of Native Plant Communities In Great Salt Lake Wetlands: The Effects Of Native Seed Mix Composition And Sowing Density, Laura Beck Apr 2021

Revegetation Of Native Plant Communities In Great Salt Lake Wetlands: The Effects Of Native Seed Mix Composition And Sowing Density, Laura Beck

Student Research Symposium

One of the threats currently facing Great Salt Lake wetlands is Phragmites australis. Its rapid expansion since 1987 has displaced native vegetation and changed the composition of plant communities. Removal is very costly and takes multiple years of different treatments like herbicide, mowing, and flooding. To ensure Phragmites australis does not return, native seeds will need to be sown. This experiment is to determine the best seed composition and sowing density. In the USU greenhouse, I will sow four different native seed mixes: 100% desirable perennial natives, 75% perennial natives and 25% fast growing natives, 50% perennial natives and 50% …


Effect Of Locality Recognition On Aggressive Behavior In The Red Swamp Crayfish, Procambarus Clarkii, Brett K. Muramoto, Tyler Farley Mar 2019

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 …


Simulating The Dispersal Of Invasive Clams In A Freshwater Lake Using A Three-Dimensional Hydrodynamic Model; A Prototype For Simulating Invasions In Marine Ecosystems, Elizabeth Kilanowski, Lambert Rubash Jan 2016

Simulating The Dispersal Of Invasive Clams In A Freshwater Lake Using A Three-Dimensional Hydrodynamic Model; A Prototype For Simulating Invasions In Marine Ecosystems, Elizabeth Kilanowski, Lambert Rubash

Salish Sea Ecosystem Conference

The discovery of several populations of an invasive Asian clam (corbicula fluminea) in Lake Whatcom, the drinking water source for approximately 100,000 people in Northern Washington State, created a need among elected officials, local government staff, and the public for a better understanding of lake hydrodynamics during the reproductive season for the Asian clam, and for times when Quagga and Zebra mussel invasions are likely. Seasonal vertical thermal stratification of the lake and a desire to predict likely locations of additional clam populations or of new populations of mussels led to the choice of a model that could be configured …


Global Change Factors On Ecosystem Invasibility, Raj Lal, Jeffrey Dukes, Michael J. Schuster, Nick G. Smith Oct 2013

Global Change Factors On Ecosystem Invasibility, Raj Lal, Jeffrey Dukes, Michael J. Schuster, Nick G. Smith

The Summer Undergraduate Research Fellowship (SURF) Symposium

Current climate and human-induced changes are projected to alter many regimes of ecosystem functioning. It is projected that invasive species, nonnative species that can be of great detriment to an ecosystem, will benefit under these conditions. The Prairie Invasion and Climate Experiment (PRICLE) studies the effects of two global change factors – N addition and altered precipitation – on invasive species success and the traits that are selected for in a mixed-grass prairie ecosystem. PRICLE is a two by two factorial design over three replications in a restored mixed-grass prairie ecosystem. The major findings from the community traits examination of …
