Book Synopsis Predicting Invasive Plant Species Range Expansion in Alaska by : Elizabeth Michelle Bella
Download or read book Predicting Invasive Plant Species Range Expansion in Alaska written by Elizabeth Michelle Bella and published by . This book was released on 2009 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Alaska is vulnerable to a variety of changes causing by a warming climate. Alaska is no longer thought to be immune to wide scale invasive plant species infestations. Planning tools are needed to anticipate area of potential change and to indentify invasive species of concern. I conducted a field study to determine presence or absence of any non-native vascular plant species per 100 m of transect keyed to vegetation type, canopy cover class, aspect, visitor use level, and use intensity on all major trails on and near Forest Service lands on the Kenai Peninsula, Alaska. Trailheads are thought to be sites of non-native species introduction to trail systems. Little is known about the number of introductions needed to establish a non-native species in northern climates, or the expected distances a particular species can be expected to spread up a trail. Prediction of non-native species spread along Alaskan trails is possible by examining vegetation type and intensity of use, with greatest impacts in open types with high use. I used biogeoclimatic models to forecast potential vulnerabilities with respect to invasive species distribution in Alaska. I selected three invasive plant species of interest in Alaska with different current distribution (reed canarygrass, present and widespread; purple loosestrife, present and limited; and leafy spurge, not yet present but considered potentially invasive). Species were modeling using two different predictive models (BIOCLIM in the DIVA-GIS platform and MaxEnt), two different future climates (Hadley and CCC), two emissions scenarios (A2, high and B2, low), for current climate plus three time steps (2020, 2050, 2080). Models were assessed with 25% test data, and then trained with 75% of the data. MaxEnt models performed better than DIVA-GIS models. All models showed current potential range that exceeds their known occurrence. For each species, we compared area difference in predicted habitat suitability between scenarios and between time steps in both models as a quantified measure of potential habitat change. I applied the modeling procedure to an additional twenty-four species to create an atlas of scenario maps for Alaska. All models showed current potential range that exceeds their known occurrence"--Leaves ii-iii.
Book Synopsis The Invasive Plant Melilotus Alba in Alaska by : James Sowerwine
Download or read book The Invasive Plant Melilotus Alba in Alaska written by James Sowerwine and published by . This book was released on 2009 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invading plants may cause biochemical changes to native plants by altering resource availability, thereby also changing the forage quality of native plants for native browsers. I measured plant growth, carbon and nitrogen content, and tannin and total phenolic production, which generally lower forage quality, in the boreal native Salix alaxensis under differing scenarios of invasion by nitrogen-fixing Melilotus alba. Additionally, I evaluated whether different populations of M. alba in Alaska suspected of having different introduction histories varied in competitive ability. I found that in this common garden experiment shading and soil nitrogen levels consistent with those found in M. alba populations did not significantly negatively affect S. alaxensis forage quality. Increase in soil nitrogen was associated with overall greater available protein levels in the willows. Last, I found no differences in competitive abilities among populations from different regions around the state, indicating all populations should be treated as equally invasive.

Book Synopsis Invasive Elodea Threatens Remote Ecosystem Services in Alaska by : Tobias Schwoerer
Download or read book Invasive Elodea Threatens Remote Ecosystem Services in Alaska written by Tobias Schwoerer and published by . This book was released on 2017 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation links human and ecological systems research to analyze resource management decisions for elodea, Alaska's first submerged aquatic invasive plant. The plant likely made it to Alaska through the aquarium trade. It was first discovered in urban parts of the state but is being introduced to remote water bodies by floatplanes and other pathways. Once introduced, elodea changes freshwater systems in ways that can threaten salmon and make floatplane destinations inaccessible. The analysis integrates multiple social and ecological data to estimate the potential future economic loss associated with its introduction to salmon fisheries and floatplane pilots. For estimating the effects on commercial sockeye fisheries, multiple methods of expert elicitation are used to quantify and validate expert opinion about elodea's ecological effects on salmon. These effects are believed to most likely be negative, but can in some instances be positive. Combined with market-based economic valuation, the approach accounts for the full range of potential ecological and economic effects. For analyzing the lost trip values to floatplane pilots, the analysis uses contingent valuation to estimate recreation demand for landing spots. A spatially-explicit model consisting of seven regions simulates elodea's spread across Alaska and its erratic population dynamics. This simulation model accounts for the change in region-specific colonization rates as elodea populations are eradicated. The most probable economic loss to commercial fisheries and recreational floatplane pilots is $97 million per year, with a 5% chance that combined losses exceed $456 million annually. The analysis describes how loss varies among stakeholders and regions, with more than half of statewide loss accruing to commercial sockeye salmon fisheries in Bristol Bay. Upfront management of all existing invasions is found to be the optimal management strategy for minimizing long-term loss. Even though the range of future economic loss is large, the certainty of long-term damage favors investments to eradicate current invasions and prevent new arrivals. The study serves as a step toward risk management aimed at protecting productive ecosystems of national and global significance.

Book Synopsis Invasive Plants and Pollination of Alaskan Berry Species by : Katie Villano Spellman
Download or read book Invasive Plants and Pollination of Alaskan Berry Species written by Katie Villano Spellman and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A rapidly changing climate and human disturbance patterns have accelerated the spread of invasive plants species in Alaska. Non-native plant invasions can disrupt pollinator services to native plants and have the potential to impact the pollination and fruit set in berry species important for subsistence harvest. My dissertation aims to address the dual need for greater understanding of the impacts of invasive plants on pollination of berry species in boreal ecosystems and the need for research on education strategies that best prepare Alaskans to respond to the issue. I integrate an ecological field experiment, a citizen science program where data is used to validate phenology models derived from heraium data, and an invasive plants education experiment testing the effects of a metacognitive learning intervention to provide multiple perspectives that inform the management of invasive plants in Alaska. The ecological field experiment found that invasive Melilotus albus acts as a magnet species for pollinators, which increased seed production in Vaccinium vitis-idaea, slightly decreased pollination in Rhododendron groenlandicum, and had no detectable interactions with Vaccinium uliginosum. The impact M. albus had on R. groenlandicum changed with distance from the invasive plant patch, but the impact on V. vitis-idaea did not. Using data from a statewide citizen science program monitoring the phenology of these species, I found that herbarium-based phenology models were valid for assessing relative shifts in phenology of these species across Alaska. Employing the research on M. albus and the berry species as a test case, I found that students who received the metacognitive learning intervention show long-term improvement in metacognitive skills compared to students in the control group, but that the groups did not differ in their ability to apply resilience thinking skills to the environmental problem-solving. I synthesized social-ecological resilience and education research to investigate how citizen science and metacognitive learning could contribute to the capacity of Alaskans to respond to social-ecological change. Together, the ecology and education research presented here provide diverse perspectives on how to best manage and build the human capacity to manage M. albus near subsistence plant species.
Book Synopsis A Handbook of Global Freshwater Invasive Species by : Robert A. Francis
Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2012-03-12 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.
