An analysis of the effectiveness of law and policy in assisting in control and prevention of non-native invasive species spread in England and Wales.
Non-Native Invasive Species (NNIS) are recognised globally as a significant threat to biodiversity. As part of an island nation with longstanding global trading links, England and Wales are particularly susceptible to the threats that NNIS pose. Although current law and policy identify these …

The Relationship Between Salvinia molesta Infestation and the Microbial Ecology of Wetlands at Caddo Lake, TX, USA
… within a wetland. The establishment of non-native invasive species within wetlands has the potential to alter the once beneficial functionality of wetland microbial communities due to the sensitivity microbes have towards environmental changes. Because of this, several metagenomic …

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 …

Monitoring biodiversity of San Francisco Peninsula grasslands using Lepidoptera as a bioindicator
… Peninsula grasslands have seen an influx of non-native invasive species starting in the 1500’s, threatening ecological stability by reducing biological diversity. To combat these invasive species, multiple public agencies have begun to adopt an integrated pest management (IPM) approach. This …

Floristic quality assessment of grassy slough preserve in Johnson County, Illinois
… replanted or contracted for replanting into tree species. There are few studies published on woody species composition during the earliest stages of old field succession in bottomland forest, and even less old field succession focusing on the herbaceous as well as the woody component in bottomland …

Plant communities along Irish roads: the impact of humans and potential to improve biodiversity
… adjacent fields plus reference points in the non-road landscape. In addition, a controlled experiment was undertaken to assess the vulnerability of road verges (which followed different landscape treatments) to invasive non-native species. Regarding species richness, the road verge habitat was …

Effects of plant invasions on ecosystem processes: Linking above- and below-ground resource-use strategies of native and invasive species in Eastern U.S. forests
<p>Despite the increasing number of non-native invasive species worldwide and their potential impacts on ecosystems, the mechanisms that invaders alter ecosystem nutrient processes remain elusive. Invaders are often more productive than native species which suggests invaders may have different …

Competitive Effects Of Increased Plant Species Richness And Increased Endemic Versus Native Generalist Species Dominance On The Invasive Grass Microstegium Vimineum During Oak Woodland Restoration
The hypothesis that species-rich assemblages are resistant to invasion by non-native species has generated considerable research and controversy. However, the relevance of such research to the conservation of biodiversity is questionable, given that local species richness often does not correlate …

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 …

Functional traits and resource-use strategies of native and invasive plants in Eastern North American forests
<p>Despite the presumption that native species are well adapted to their local environment, non-native invaders seem to outperform native plants. Intuitively, it appears paradoxical that non-native species, with no opportunity for local adaptation, can exhibit greater fitness than native plants …

A comparative study of the population dynamics of four Amaranthaceae species
… and Iresine rhizomatosa are two perennial species in the same family as A. palmeri and A. tuberculatus that occur in similar habitats as one another, but differ in invasiveness. Achyranthes japonica is a non-native, invasive species that is becoming a threat to forested areas and has been …

Effects of Amur Honeysuckle (Lonicera maackii [Rupr.] Herder) Invasion and Removal on Native Vegetation and White-Footed Mice (Peromyscus leucopus) in Mixed-Hardwood Forests of Indiana
<p>The threat of non-native invasive species continues to compromise the ecological and economic integrity of our natural resources. Numerous investigators have documented the negative effects of invasive species on native biota. However, much work is still needed with regard to how invasive …
