The influence of native plants on arthropod population dynamics: can native plants enhance conservation biological control
… alien vegetation is being planted; these plants may be unacceptable hosts for herbivores. We tested the prediction that urban landscapes composed of native plants host a diverse herbivore population and attract and sustain a diverse community of natural enemies relative to landscapes …

Native plants as sentinels of tritium contamination
… earthen caps covering radioactive waste. The plants, grown in hydroponic tanks and 3 m columns, were evaluated for treatments representing three different levels of tritium contamination. Tritium, a radioactive isotope of hydrogen, replaces a hydrogen atom in a water molecule and readily …

Interactions between Bromus tectorum, grasshoppers, and native plants in sagebrush steppe communities
… that B. tectorum dominance is enhanced by native herbivores through the mechanism of apparent competition: species competing indirectly through shared natural enemies. If an invasive exotic is a less preferred food source for herbivores than native plants, per capita feeding impacts may …

CAN SHEEP CONTROL LEAFY SPURGE WITHOUT COMPROMISING EFFORTS TO RESTORE NATIVE PLANTS?
… strategy, little is known about their impacts on native plants. The efficacy of sheep grazing for restoration depends both on its potential for controlling undesirable plants and its ability to promote native species that provide key ecosystem goods and services. I investigated the effects of …

Restoration through reassembly: evaluating the role of native plants in combatting Chinese tallow
<p>Non-native, invasive species disrupt ecological processes and functions, posing a serious threat to natural ecosystems. By examining the growth metrics of the non-native, invasive tree, Chinese tallow (<em>Triadica sebifera</em> [L.] Roxb.), hereafter tallow, across different flooding and light …

A triadic relationship on the northern Great Plains: bison (Bison bison), native plants, and native people
… relationship that exists among Bison bison, native plants, and Native People. An exhaustive in-depth review of each ecological component is given. Lakota Indian participants were interviewed for their qualitative knowledge of the three ecological components being studied. Interviewees were …

Safe Haven Leveling the Playing Field by Creating a Home for the Unsheltered, Homeless, Water, and Native Plants
… spaces, keep water in storm drains, and keep native plants on the periphery of the public landscape, my project, Safe Haven, is about creating an inclusive public landscape for people, water, and native plants. Preliminary research into the history of property ownership, discrimination, …

Field and Greenhouse Studies of Phytoremediation with California Native Plants for Soil Contaminated with Petroleum Hydrocarbons, PAHs, PCBs, Chlorinated Dioxins/Furans, and Heavy Metals
<p>Native and naturalized California plant species were screened for their phytoremediation potential for the cleanup of soil contaminated with petroleum hydrocarbons (PHCs), poly-aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), chlorinated dioxins/furans, and heavy metals. This …

Exotic Bird Invasion Into Forests of Hawaii: Demography, Competition, and Seed Dispersal
… did have a strong and conspicuous impact on native and non-native plants. In an ecosystem where most native frugivores are extinct, introduced birds dispersed all common native plants in these forest sites but non-native plants were infrequently eaten and dispersed. Furthermore, introduced …

Ecosystem services provided by native New Zealand plants in vineyards
This thesis investigates the value of native New Zealand plants within the agricultural landscape of the Waipara District, Canterbury Province, New Zealand with regards to their provision of ecosystem services (ES). ES have undergone extensive study with the conclusion that they are vital to …

Investigations of Bromus tectorum: restoration strategies and interactions with arbuscular mycorrhizal fungi
… pervasive weeds in the United States, reduces native species diversity and transforms habitats. I conducted four experiments designed to better understand B. tectorum ecology and evaluate control and restoration strategies. I measured the responsiveness of six native plants and B. tectorum to …

The Use of Native Hawaiian Plants by Landscape Architects in Hawaii
Hawaii has lost significant numbers of native flora and fauna resulting from introduced grazing animals, invasive flora, fire and a loss of habitat due to urbanization and agricultural use. Scientists believe that protecting these plants can be achieved by eliminating or reducing threats to native …

Effects of repeated early season herbicide treatments of curlyleaf pondweed on native macrophyte assemblages in Minnesota Lakes.
Non-native invasive species have the potential to cause various problems in small isolated ecosystems, these constraints are exemplified in the small, shallow, lakes of Minnesota. Curlyleaf pondweed (Potamogeton crispus L.) is one of the common occurring and most influential non-native invasive …

Interactions Among Invasive Species in Lakes: a Mesocosm Experiment
… Rusty crayfish significantly reduced biomass of native snails, but not the invasive BMS. Overall, main effects of RC on native plants and snails were much greater than effects of either EWM or BMS, or the combined effects of these invaders. These impacts, together with the rapid production and …

Native Bees and Pollen Collection: How Flexible Are They?
… and thus the reproduction of crops and wild plants. Native bees may be a free source of pollination services and act as ‘insurance’ against potential honey bee losses in Australia. This study aims is to determine whether native bees collect pollen mainly from native plants, with which they …

Effects of biochar, subsoiling, and native seeding on the establishment of pollinator habitat in log landings
… seeding of 31 competitive, pollinator-friendly native plants. Study treatments included a biochar amendment to the soil, subsoiling to reduce compaction, a combination of subsoiling and biochar, and a control treatment. Results show that soil treatments had little impact on the developing …

Impacts of Deer and Honeysuckle on the Endangered Trillium Reliquum and Its Associated Plant Community
The effects of herbivores and invasive plants on native plants are well known, but few studies have addressed their impacts on rare plants. Threatened or endangered plant species may be more susceptible to negative effects of biotic factors due to their already low distributions. My study …
