Article
An understanding of the demographic processes contributing to invasions would improve our mechanistic understanding of the invasion process and improve the efficiency of prevention and control efforts. However, field comparisons of the demography of invasive and noninvasive species have not previously been conducted. We compared the in situ demogra...
Article
Plant‐associated fungi can ameliorate abiotic stress in their hosts, and changes in these fungal communities can alter plant productivity, species interactions, community structure and ecosystem processes. We investigated the response of root‐associated fungi to experimental drought (66% reduction in growing season precipitation) across six North A...

Transmission of information has benefitted from a breathtaking level of innovation and change over the past 20 years; however, instructional methods within colleges and universities have been slow to change. In the article, we present a novel framework to structure conversations that encourage innovation, change, and improvement in our system of hi...
Article
Full-text available
Interactions between plants and microbes have important influences on evolutionary processes, population dynamics, community structure, and ecosystem function. We review the literature to document how climate change may disrupt these ecological interactions and develop a conceptual framework to integrate the pathways of plant-microbe responses to c...
Article
Questions Reordering of dominant species is an important mechanism of community response to global environmental change. We asked how wildfire (a pulse event) interacts with directional changes in climate (environmental presses) to affect plant community dynamics in a Chihuahuan Desert grassland. Location Sevilleta National Wildlife Refuge, Socorr...

Aims Biological soil crusts (biocrusts) dominate soil surfaces in drylands, providing services that include soil stabilization and carbon uptake. In this study, we investigated the direct and biocrust-mediated effects of anthropogenic disturbances in two dryland ecosystems. Methods We applied low intensity soil surface disturbance (twice-yearly fo...
Article
Full-text available
Investigations of plant-soil feedbacks (PSF) and plant-microbe interactions often rely exclusively on greenhouse experiments, yet we have little understanding of how, and when, results can be extrapolated to explain phenomena in nature. A systematic comparison of microbial communities using the same host species across study environments can inform...
Article
Temporal fluctuations in plant species coexistence are key to understanding ecosystem state transitions and long‐term maintenance of species diversity. While plant microbiomes can alter plant competition in short‐term experiments, their relevance to natural temporal patterns in plant communities is unresolved. In a semiarid grassland, the frequency...
Article
Patterned vegetation growth such as grass rings is found in many arid ecosystems, yet the mechanisms behind their formation are often unknown and have been minimally tested in the field. One explanation is pathogen accumulation in the center of a long-lived plant, which could cause central dieback and the formation of a ring as the plant grows towa...
Article
Understanding controls on net primary production (NPP) has been a long-standing goal in ecology. Climate is a well-known control on NPP, although the temporal differences among years within a site are often weaker than the spatial pattern of differences across sites. Climate sensitivity functions describe the relationship between an ecological resp...
Article
Increased atmospheric nitrogen (N) deposition can have wide-ranging effects on plant community structure and ecosystem function, some of which may be indirectly mediated by soil microbial responses to an altered biogeochemical environment. In this study, soils from a field N fertilization experiment that spanned a soil texture gradient were used as...
Article
Understanding the mechanisms of species coexistence is key to predicting patterns of species diversity. Historically, the ecological paradigm has been that species coexist by partitioning resources: as a species increases in abundance, self-limitation kicks in, because species-specific resources decline. However, determining coexistence mechanisms...
Article
1.A potential driver of species abundance that remains understudied is the interaction between host species and their microbial symbionts. Beneficial symbionts could promote the dominance of common host species by increasing their population growth rates more than they do for rare species, and symbiont benefits could be important for maintaining ra...
Article
Full-text available
Mutualisms can play important roles in influencing species coexistence and determining community composition. However, few studies have tested whether such interactions can affect species distributions by altering the niches of partner species. In subalpine meadows of the Rocky Mountains, USA, we explored whether the presence of a fungal endophyte...
Article
Full-text available
Biological invasions can strongly influence species interactions such as pollination. Most of the documented effects of exotic plant species on plant-pollinator interactions have been observational studies using single pairs of native and exotic plants, and have focused on dominant exotic plant species. We know little about how exotic plants alter...
Conference Paper
Background/Question/Methods Plant-soil microbe interactions have high potential as a stabilizing mechanism of coexistence in plant communities. For example, density-dependent pathogen accumulation in plant roots will result in negative feedback which keeps species from outcompeting others. Past research has shown that the effects of soil microbes...
Conference Paper
Background/Question/Methods Plants interact with a diversity of microbial symbionts throughout their life cycle. However, these interactions are not static throughout the lifetime of the host plant, and it is possible that a symbiont may have positive or negative effects on its host depending on the life stage. How do these combinations of costs...
Conference Paper
Background/Question/Methods Biological invasions can be highly disruptive to native communities through direct competition and predation, or indirectly by altering existing abiotic environments or biotic interactions. Plant-pollinator interactions are an example of a critical ecosystem service that has suffered detrimental effects from exotic pla...
Conference Paper
Background/Question/Methods By understanding the relative importance of different processes to invasion speed we can better predict and control biological invaders, thus helping to preserve natural resources and ecosystem functioning. We conducted a phylogenetically controlled comparative study of the roles of demography and dispersal in governing...
Conference Paper
Background/Question/Methods Animal pollination is a critical ecosystem service required by over 90% of flowering plants. Like other interspecies interactions, this service is being disrupted by the introduction of invasive alien species. Recent studies have mostly focused on single species of plants or pollinators, however, less is known about how...
