Evolutionary Dynamics of Brown Treesnake (Boiga irregularis) Reproductive Ecology, with Implications for Invasive Species Control
<p>Invasive species represent major threats to biodiversity, global economies, and human health. Consequently, extensive research has been directed towards improving methods that restrict and contain them. Yet, control measures can also act as agents of selection by significantly impacting the …

Riparian Restoration, Success Criteria, and Application to the BART Sabrecat Creek Riparian Restoration Project in Fremont, California
… habitat, and riparian buffers; special-status species, endangered species, and habitat type and structure; invasive species control; water quality and hydrology; and soil and soil microbial communities. Three methods of evaluating restoration projects are discussed, including the Society for …

Disturbance impacts on non-native plant colonization in black spruce forests of interior Alaska
… have historically been relatively free from invasive plants, there have been recent increases in the diversity and range of invasive plants in Alaska. It is critical that we understand how disturbances influence invasibility in northern boreal forests, to avoid the economic damage other …

Restoring Abandoned Agricultural Lands in Puget Lowland Prairies: A New Approach
… and has focused on extant sites with some native species present. Generally, actions first began with invasive species control, followed by reintroduction of fire, and then seeding and planting. Significant improvements have been made, however existing habitat continues to be converted and …

Lowland savanna of southeastern Iowa: historical and modern vegetation patterns and implications for management
… woodland areas, as well as those dominated by invasive Phalaris arundinacea (reed canary grass). Overstory and understory vegetation composition and abundance, elevation, ground level light, depth of inundation, soil texture, soil carbon, and soil nitrogen were measured in study plots and …

Making biosecurity, making Mexico : an ethnography of biological invasion
… that underwrite biosecurity in three areas: invasive species control, emerging infectious disease research, and the use of transgenic organisms. I examine how conservationists working in Mexican settings - particularly on islands - alternately protect or exterminate the various life forms …

Essays on Dynamic Optimization for Forest Resource Management
… on investigating the ecosystem collapse and invasive species control problems. The first two papers consider the shift from primary forests to cleared land and secondary forests in the context of deforestation. This process is known to lead to irreversible tipping points that lead to the loss …

Determining the Influence of Abiotic and Biotic Predictors on Ecological Niche Models
… assumed to have negligible effects on broadscale species distributions and are typically excluded from ecological niche models (ENMs). However, the role such interactions play in shaping species distributions is increasingly recognized, sparking the development of methods for their integration …

A holistic approach to Mima mound prairie restoration
<p>"Invasive winter annual grass (IWAGs) abundance has increased throughout much of the western United States, with serious consequences for biodiversity and ecosystem function. While a variety of tools have been used to control IWAGS, they often fail to achieve the goal of creating a …

A Novel Mathematical Model of the Trojan Y-Chromosome Strategy with Optimal Control
<p>Invasive species are a prevalent problem all over the world. Controlling and eradicating an invasive species is an even more diffcult problem. The Trojan Y Chromosome (TYC) eradication strategy is one control method. This method alters the female to male sex ratio by introducing sex reversed …
