Introduction
I am a plant community and invasion ecologist, with research interests in how large scale natural and anthropogenic disturbances and invasions affect communities and ecosystems at different spatial scales. My current projects study sustainable management of urban green spaces for multiple ecosystem services and biodiversity conservation. Key Words: native and invasive species, global environmental changes, urban ecosystem, community resilience, ecosystem services, perennial grasslands.

Aims We compared the degree of arbuscular mycorrhizal fungi (AMF) colonization on an invasive, Triadica sebifera, and two native, Baccharis halimifolia and Morella cerifera, woody species that occur in coastal Mississippi, USA. Specifically, we investigated how the degree of colonization affects growth of these species and assessed potential allelo...
Article
A mounting body of research suggests that invasive non-native earthworms substantially alter microbial communities, including arbuscular mycorrhizal fungi (AMF). These changes to AMF can cascade to affect plant communities and vertebrate populations. Despite these research advances, relatively little is known about: (1) the mechanisms behind earthw...
Article
Invasions of non-native earthworms into previously earthworm-free regions are a major conservation concern because they alter ecosystems and threaten biological diversity. Little information is available, however, about effects of earthworm invasions outside of temperate and boreal forests, particularly about invasions of islands. For San Clemente...

Soil organisms, including earthworms, are a key component of terrestrial ecosystems. However, little is known about their diversity, their distribution, and the threats affecting them. We compiled a global dataset of sampled earthworm communities from 6928 sites in 57 countries as a basis for predicting patterns in earthworm diversity, abundance, a...
Article
The Great Plains of North America encompass approximately 1,300,000 km² of land from Texas to Saskatchewan. The integrity of these lands is under continual assault by long-established and newly-arrived invasive plant species, which can threaten native species and diminish land values and ecological goods and services by degrading desired grassland...

Increasing demand for agricultural products is driving grassland management intensification with subsequent impacts on ecosystem services and disservices. Key questions related to grassland production as well as environmental and social concerns must be addressed to ensure sustainability. We propose a unified perspective, addressing numerous trade‐...

Earthworms are an important soil taxon as ecosystem engineers, providing a variety of crucial ecosystem functions and services. Little is known about their diversity and distribution at large spatial scales, despite the availability of considerable amounts of local-scale data.

Hurricane disturbances produce significant changes in forest microclimates, creating opportunities for seedling regeneration of native and invasive plant species alike. However, there is limited information on how changes in microclimates and pre-existing forest conditions affect native and invasive plants responses to hurricane disturbances. In th...

Quantifying the economic impacts of invasive species is an essential step in developing and prioritizing invasive species management. In particular, kudzu, Pueraria montana (Lour.) Merr. is an aggressive and non-native vine that not only causes ecological damage and reduces biodiversity, but can have multiple economic consequences such as loss of t...

Article
Full-text available
Low-lying coastal ecosystems along the northern Gulf of Mexico are already experiencing the effects of elevated salinity from sea-level rise and are predicted to face extreme events such as extended saltwater inundation, intense Atlantic hurricanes, and episodic drought. The ability of coastal plant communities to survive stresses from these events...

Full-text available
Drawing on a long history in macroecology, correlation analysis of microbiome datasets is becoming a common practice for identifying relationships or shared ecological niches among bacterial taxa. However, many of the statistical issues that plague such analyses in macroscale communities remain unresolved for microbial communities. Here, we discuss...

How the relative frequency of co-absent sites impacts Pearson’s correlation coefficient. A simulation shows how an increase in the frequency of co-absent sites ([–,–] in the occurrence matrix; denoted by red d relative to that of co-present and mutual-exclusion sites (b, c) inflates Pearson’s correlation coefficient, often changing the direction of...

Understanding the relative importance of environmental and anthropogenic factors in driving plant community structure, including relative dominance of native and non-native species, helps predict community responses to biological invasions. To assess factors influencing plant communities on San Clemente Island, USA, we conducted an islandwide veget...

European and Asian earthworms have invaded much of North America with profound impacts to soils, plant communities, and animal populations. However, few studies have assessed local-scale correlates of earthworm distributions, and most invasive earthworm research has occurred in northern forests. Additionally, despite several studies showing facilit...

In this paper, we compared the structure, composition, and diversity of trees, shrubs and saplings, seedlings and herbaceous species of community- and government- managed forests in low-lands of eastern Nepal. Results suggest that among trees, the community forest was dominated by single species, Shorea robusta. However, Shorea robusta and Terminal...

Background/Question/Methods Identifying the spatial distribution, abiotic and biotic associations, and ecological effects of newly introduced species is an important first step to developing management and control measures. Non-native earthworms, including species from Europe and Asia, have invaded much of the northeastern and Great Lakes deciduous...

Distribution patterns of plant species are believed to be impacted by small-scale habitat heterogeneity. However, there have been few comparative studies examining how woody vegetation composition and diversity varies with aspects of different orientations in the Trans-Himalayan region at a local scale. Here, we examined the effects of incoming sol...

With sea level rise, coastal ecosystems farther in- land are expected to experience extended duration of inunda- tion and elevated salinity. However, the effects of elevated salinity on initial recruitment of native and invasive woody species in coastal ecosystems are poorly understood. We assessed effects of elevated salinity across a range of soi...

Background/Question/Methods Low lying coastal ecosystems of the Mississippi River deltaic plain are vulnerable to sea-level rise and hurricane disturbances and exotic species invasions. In flooded backswamps, widespread replacement of native species by exotics also threatens the ecological integrity of the floating aquatic communities. Exotic-dom...
Conference Paper
Background/Question/Methods Coastal ecosystems along the northern Gulf of Mexico are predicted to experience intensification of tropical storms and sea-level rise during this century. These disturbances usually result in significant changes in forest microclimate which may provide opportunities for the growth and regeneration of exotics that inva...

The physiochemical properties of soils of two different types of forests (pure Shorea robusta and mixed Shorea robusta) were analyzed. Soil samples were collected from both types of forest and analyzed for texture, pH, organic matter, humus content, water holding capacity, nitrogen, phosphorous and potassium. In both the pure and mixed forest, soil...
