The cold snap that left the reptiles falling catatonic from trees had residents dusting off recipes for an invasive species whose meat sells for $60 a pound...
Across the nation, USDA Forest Inventory and Analysis collects data on forest ecosystems, including soils, microbes, land ownership, carbon, invasive plants, and of course, trees. Every two years, experts from the U.S. and beyond gather to share their knowledge. The 2019 FIA Stakeholders Science Meeting was held in Knoxville, Tennessee from November 19-21. The National […]...
Research Highlights: We demonstrate a macroscale framework combining an invasibility model with forest inventory data, and evaluate regional forest exposure to harmful invasive plants under different types of forest protection. Background and Objectives: Protected areas are a fundamental component of natural resource conservation. The exposure of protected forests to invasive plants can impede ach...
Understanding the successes and failures of nonnative species remains challenging. In recent decades, researchers have developed the enemy release hypothesis and other antagonist hypotheses, which posit that nonnative species either fail or succeed in a novel range because of the presence or absence of antagonists. The premise of classical biological control of invasive species is that top-down co...
An invasive species of seaweed which has blighted tourist beaches in Mexico has become more aggressive due to the heating effects of climate change. But now, thanks to support from the UN Development Programme (UNDP), efforts are underway to hold back its advance and protect local ecosystems....
As Egypt marks the 150th anniversary of the opening of the Suez Canal, marine biologists are bemoaning one of the famed waterway's lesser known legacies-the invasion of hundreds of non-native species, including toxic jellyfish and aggressive lionfish....
While generality is often desirable in ecology, customized models for individual species are thought to be more predictive by accounting for context specificity. However, fully customized models require more information for focal species. We focus on pest spread and ask: How much does predictive power differ between generalized and customized models? Further, we examine whether an intermediate &qu...
Department of Fisheries and Oceans scientists say there's no point trying to save some of the native fish in a New Brunswick lake that may soon be deliberately poisoned....
In eastern Panama, canid species from North and South America are occurring together for the first time. Urban and agricultural development and deforestation along the Mesoamerican Biological Corridor might be generating a new passageway for these invasive species adapted to human disturbance....
Invasive species remain one of the greatest threats to the productivity and sustainability of agriculture, forests, prairies and wetlands (Lovett et al., 2016; Paini et al., 2016). By definition these species are alien (i.e. non-native) to some ecosystems in which they now occur. In their adventive geographic range, they lack co-evolutionary history with the native flora and fauna. As a result, ho...
1. Traits of non-native insect herbivores may vary spatially due to local genetic differences, rapid post-introduction evolution, and/or novel host plant associations. 2. Populations of larch casebearer, Coleophora laricella Hübner, originally from Europe have likely been isolated for >60 years in North America on eastern larch, Larix laricina (Du Roi) K. Koch, and western larch, Larix occ...
Urban areas around the world are increasingly investing in networks of urban forests, gardens, and other forms of green infrastructure for their benefits, including enhanced livability, sustainability, and climate change mitigation and adaptation. Proactive planning for climate change requires anticipating potential climate change impacts to green infrastructure and adjusting management strategies...
