Eco‐evolutionary context modifies a destructive plant invader's response to climate

Megan L. Vahsen, Justin J. Van Ee, Diana Gamba, Toby M. Maxwell et autres

Understanding the relationship between climate and fitness will be important when predicting how plant populations respond to climate change. We conducted a replicated common garden experiment (4 sites × 2 yr) with 96 genotypes (n = 22 492 individuals) of the invasive …

PAVC: The foundation for a Pan-Arctic Vegetation Cover database

Morgan R Steckler, Jitendra Kumar, Amy Breen, Tianqi Zhang et autres

Field-measured Arctic vegetation cover data is essential for creating accurate, high-quality vegetation structure and composition maps. Extrapolating field data into high-resolution cover maps provides detailed, function-specific information for use in Earth System Models, vegetation classifications, and monitoring vegetation change over time and …

Why are non‐native plants successful? Consistently fast economic traits and novel origin jointly explain abundance across US ecoregions

Dana M. Blumenthal, Jeffrey M. Diez, Ian S. Pearse, Helen R. Sofaer et autres

Are non-native plants abundant because they are non-native, and have advantages over native plants, or because they possess 'fast' resource strategies, and have advantages in disturbed environments? This question is central to invasion biology but remains unanswered. We quantified the relative importance …

A Quantitative Classification of the Geography of Non‐Native Flora in the United States

Bethany A. Bradley, Annette E. Evans, Helen R. Sofaer, Montserrat Vilà et autres

ABSTRACT Aim Non‐native plants have the potential to harm ecosystems. Harm is classically related to their distribution and abundance, but this geographical information is often unknown. Here, we assess geographical commonness as a potential indicator of invasive status for non‐native flora in …

Using Plant Invasions to Compare Occurrence‐ and Abundance‐Based Calculations of Biotic Homogenisation: Are Results Complementary or Contradictory?

D. M. Buonaiuto, David T. Barnett, Dana M. Blumenthal, Andrea N. Nebhut et autres

ABSTRACT Aim Beta diversity quantifies the similarity of ecological assemblages. Its increase, known as biotic homogenisation, can be a consequence of biological invasions. However, species occurrence (presence/absence) and abundance‐based analyses can produce contradictory assessments of the magnitude and direction of changes in …

Naturalized species drive functional trait shifts in plant communities

Magda Garbowski, Daniel C. Laughlin, Dana M. Blumenthal, Helen R. Sofaer et autres

Despite decades of research documenting the consequences of naturalized and invasive plant species on ecosystem functions, our understanding of the functional underpinnings of these changes remains rudimentary. This is partially due to ineffective scaling of trait differences between native and naturalized species …

Macroscale analyses suggest invasive plant impacts depend more on the composition of invading plants than on environmental context

Evelyn M. Beaury, Helen R. Sofaer, Regan Early, Ian S. Pearse et autres

Abstract Aim Native biodiversity is threatened by the spread of non‐native invasive species. Many studies demonstrate that invasions reduce local biodiversity but we lack an understanding of how impacts vary across environments at the macroscale. Using ~11,500 vegetation surveys from ecosystems across …

Learning from monitoring networks: Few-large vs. many-small plots and multi-scale analysis

Becky Tang, Renata Poulton‐Kamakura, David T. Barnett, James S. Clark

In order to learn about broad scale ecological patterns, data from large-scale surveys must allow us to either estimate the correlations between the environment and an outcome and/or accurately predict ecological patterns. An important part of data collection is the sampling effort …

Spatial and temporal sampling strategy connecting NEON Terrestrial Observation System protocols

Courtney L. Meier, Katherine M. Thibault, David T. Barnett

Abstract The National Ecological Observatory Network Terrestrial Observation System (NEON TOS) produces open‐access data products that allow data users to investigate the impact of change drivers on key “sentinel” taxa and soils. The spatial and temporal sampling strategy that coordinates implementation of …

Combining local, landscape, and regional geographies to assess plant community vulnerability to invasion impact

Inés Ibáñez, Laís Petri, David T. Barnett, Evelyn M. Beaury et autres

Invasive species science has focused heavily on the invasive agent. However, management to protect native species also requires a proactive approach focused on resident communities and the features affecting their vulnerability to invasion impacts. Vulnerability is likely the result of factors acting …
