Functional trait responses of emergent and free-floating Alternanthera philoxeroides to increasing salinity with sea level rise: stress tolerance, avoidance, and escape strategies Open
Sea level rise is having major impacts on estuaries due to salinity intrusion. These changes in stress profiles have ripple effects in ecosystems, including altering the invasibility of these wetlands depending on the salt tolerance of the…
Foliar fungal assemblages associated with diploid and triploid Butomus umbellatus populations in the United States Open
Novel associations between plant invaders and fungi may moderate invader impacts if fungi are pathogenic or contribute to variation in invader response to management. Identifying and quantifying species associations with plant invaders can…
A proposed method for estimating habitat suitability of weed biological control agents with experimentally derived thermal injury and weather data Open
Ecological niche modelling provides a tool for making a priori predictions of habitat suitability for biological control agents. Current approaches may be limited by available data but improved by the incorporation of physiological data. A…
The role of competition in moderating plant–soil feedback for restoring ecosystems invaded by Brazilian peppertree ( <i>Schinus terebinthifolia</i> Raddi) Open
Introduction Ecosystem restoration requires the management of invasive plants due to the harmful effects they have on both above‐ and belowground ecosystem processes. Belowground soil modifications by invasive plants, particularly those dr…
Intraspecific variation in rapid cold hardening and acclimation of the adventive parrot’s feather weevil, Phytobius (=Parenthis) vestitus, in the southern USA Open
Plasticity in thermal tolerance, expressed through acclimation or rapid cold hardening, for example, provides organisms with a mechanism to deal with unexpected and often rapid changes in the thermal environment. Spatial variation in respo…
Introduction of three cryptic lineages of invasive crested floating heart (<i>Nymphoides cristata</i>) in the southeastern United States Open
Crested floating heart [ Nymphoides cristata (Roxb.) Kuntze] is an invasive aquatic plant in the southeastern United States. For clonal plants like N. cristata , clonal diversity may influence response to control tactics and/or evolutionar…
Phenology and resource allocation strategies of diploid flowering rush (<i>Butomus umbellatus</i>) in Ohio and New York Open
Flowering rush ( Butomus umbellatus L.) is an emergent perennial monocot that has invaded aquatic systems along the U.S.–Canadian border. Currently, there are two known cytotypes of flowering rush, diploid and triploid, within the invaded …
Initial rearing, release, and establishment of biological control agent Pseudophilothrips ichini to control Brazilian peppertree (Schinus terebinthifolia) in South Texas ecosystem restoration projects Open
Control of the invasive Brazilian peppertree (Schinus terebinthifolia) is a major cost component of US Army Corps of Engineers (USACE) ecosystem restoration (ER) projects in South Texas, specifically the USACE Galveston district (SWG) Resa…
Rust disease on <i>Nymphoides peltata</i> caused by <i>Puccinia</i> sp. in Korea Open
Nymphoides peltata (Asteraceae), commonly known as 'yellow floating heart', is an aquatic plant with buoyant leaves. It is native to East Asia and commonly cultivated in garden ponds and lakes for ornamental purposes. In other regions, for…
Influence of shade and cold stratification on germination success of vegetative propagules from multiple Butomus umbellatus genotypes Open
Three experimental trials were conducted to investigate the influence of shade and cold stratification on germination success of vegetative propagules from multiple Butomus umbellatus genotypes. Shade level did not significantly impact ger…
Assessing the genetic diversity of Nymphoides peltata in the native and adventive range using microsatellite markers Open
Nymphoides peltata (yellow floatingheart), native to Eurasia, is an invasive plant in the USA, where it grows in relatively isolated but widespread populations. The species is capable of sexual reproduction by seed and asexual reproduction…
Integrating Invasive Weed Biological Control in Aquatic Ecosystem Restoration Projects Open
A primary goal of many aquatic ecosystem restoration (AER) projects is to alter and improve plant communities by increasing relative abundance of native species while reducing invasive species abundance, establishment, and spread. Biologic…
Aquatic ecosystem restoration in the Texas Western Gulf Coast Plain / Lower Rio Grande alluvial floodplain ecoregion : Resaca Boulevard Resaca Section 206—vegetation community adaptive management Open
As part of the US Army Corps of Engineers (USACE) Continuing Authorities Program (CAP), Section 206 projects focus on restoring aquatic habitats for the benefit of fish and other wildlife. From 2017–2021, USACE Engineer Research and Develo…
Multivariate evaluation of cold tolerance in domestic and foreign populations for addressing climate mismatch in biological control of <i>Alternanthera philoxeroides</i> in the <span>USA</span> Open
Lack of successful biological control of alligatorweed, Alternanthera philoxeroides (Mart.) Griseb. (Amaranthaceae), by Agasicles hygrophila Selman & Vogt (Coleoptera: Chrysomelidae) in the USA is an emerging problem as A. philoxeroides ex…
Intraspecific trait plasticity to N and P of the wetland invader, <i>Alternanthera philoxeroides</i> under flooded conditions Open
Interactions between invaders and resource availability may explain variation in their success or management efficacy. For widespread invaders, regional variation in plant response to nutrients can reflect phenotypic plasticity of the inva…

DNA assays for genetic discrimination of three <i>Phragmites australis</i> subspecies in the United States Open
Premise To genetically discriminate subspecies of the common reed ( Phragmites australis ), we developed real‐time quantitative (qPCR) assays for identifying P. australis subsp. americanus , P. australis subsp. australis , and P. australis…
Intraspecific trait plasticity to N and P of the wetland invader, Alternanthera philoxeroides under flooded conditions Open
Interactions between invaders and resource availability may explain variation in their success or management efficacy. For widespread invaders, regional variation in plant response to nutrients can reflect phenotypic plasticity of the inva…
Data from: Assessing the genetic diversity of Nymphoides peltata in the native and adventive range using microsatellite markers Open
Set of population data for Nymphoides peltata, which is an invasive plant species in the USA. Microsatellite data for eight markers, from plants in the native and adventive ranges.

Genetic analysis of North American Phragmites australis guides management approaches Open
Phragmites australis subsp. australis is an invasive and ecologically detrimental plant in multiple regions of North America. Its co-occurrence with the native subspecies, and multiple instances of hybridization, has created the need to di…
Biology of Immature Stages and Host Range Characteristics of Sudauleutes bosqi (Coleoptera: Curculionidae), a Candidate Biological Control Agent of Exotic Ludwigia spp. in the USA Open
Las plantas invasoras sudamericanas del género Ludwigia (Onagraceae) degradan muchos ecosistemas ribereños y acuáticos en todo el mun-do. El control biológico puede ayudar en el manejo de estas malas hierbas exóticas, pero los datos sobre …
Spatio-temporal pattern of cross-continental invasion: Evidence of climatic niche shift and predicted range expansion provide management insights for smooth cordgrass Open
