The rich get richer: patterns of plant invasions in the United States

John Kartesz, David T. Barnett, Thomas J. Stohlgren

Observations from islands, small-scale experiments, and mathematical models have generally supported the paradigm that habitats of low plant diversity are more vulnerable to plant invasions than areas of high plant diversity. We summarize two independent data sets to show exactly the opposite …

PLANT SPECIES INVASIONS ALONG THE LATITUDINAL GRADIENT IN THE UNITED STATES

John Kartesz, Bruce G. Peterjohn, David W. Barnett, Thomas J. Stohlgren et autres

It has been long established that the richness of vascular plant species and many animal taxa decreases with increasing latitude, a pattern that very generally follows declines in actual and potential evapotranspiration, solar radiation, temperature, and thus, total productivity. Using county-level data …

Emergence of Cross-Scale Structural and Functional Processes in Ecosystem Science

Randall B. Boone, Robert G. Woodmansee, James K. Detling, Daniel Binkley et autres

Fundamental knowledge about the processes that control the functioning of the biophysical workings of ecosystems has expanded exponentially since the late 1960s. Scientists, then, had only primitive knowledge about C, N, P, S, and H 2 O cycles; plant, animal, and soil …

Evolution of the Systems Ecology Paradigm in Managing Ecosystems

Robert G. Woodmansee, Michael B. Coughenour, Keith Paustian, William J. Parton et autres

The systems ecology paradigm (SEP) emerged in the late 1960s at a time when societies throughout the world were beginning to recognize that our environment and natural resources were being threatened by their activities. Management practices in rangelands, forests, agricultural lands, wetlands, …

A modeling workflow that balances automation and human intervention to inform invasive plant management decisions at multiple spatial scales

Nicholas E. Young, Catherine S. Jarnevich, Helen R. Sofaer, Ian S. Pearse et autres

Predictions of habitat suitability for invasive plant species can guide risk assessments at regional and national scales and inform early detection and rapid-response strategies at local scales. We present a general approach to invasive species modeling and mapping that meets objectives at …

The plant diversity sampling design for The National Ecological Observatory Network

David T. Barnett, Peter B. Adler, Benjamin R. Chemel, Paul Duffy et autres

Abstract The National Ecological Observatory Network (NEON) is designed to facilitate an understanding of the impact of environmental change on ecological systems. Observations of plant diversity—responsive to changes in climate, disturbance, and land use, and ecologically linked to soil, biogeochemistry, and organisms—result …

Field validation of an invasive species Maxent model

Amanda M. West, Cynthia S. Brown, Thomas J. Stohlgren, Jim Bromberg

Accurate and reliable predictions of invasive species distributions are urgently needed by land managers for developing management plans and monitoring new potential areas of establishment. Presence-only species distribution models are commonly used in these evaluations, however they are rarely tested with independent …

Integrating Remote Sensing with Species Distribution Models; Mapping Tamarisk Invasions Using the Software for Assisted Habitat Modeling (SAHM)

Amanda M. West, Paul Evangelista, Catherine S. Jarnevich, Nicholas E. Young et autres

Early detection of invasive plant species is vital for the management of natural resources and protection of ecosystem processes. The use of satellite remote sensing for mapping the distribution of invasive plants is becoming more common, however conventional imaging software and classification …
