Effects of Prescribed Fire, Site Factors, and Seed Sources on the Spread of Invasive Triadica sebifera in a Fire-Managed Coastal Landscape in Southeastern Mississippi, USA

In the Gulf of Mexico coastal region, prescribed fire has been increasingly used as a management tool to restore declining native ecosystems, but it also increases the threat posed by biological invasion, since the treated sites are more susceptible to invasive species such as Chinese tallow (Triadica sebifera). We chose Mississippi Sandhill Crane National Wildlife Refuge (MSCNWR), a fire-managed ...

An assessment of Canada thistle in northern U.S. forests

This publication is part of a series that provides an overview of the presence of invasive plant species monitored on an extensive systematic network of plots measured by the Forest Inventory and Analysis (FIA) program of the USDA Forest Service, Northern Research Station (NRS). Each research note features one of the invasive plants monitored on forested plots by NRS FIA in the 24 states of the Mi...

Improving ecological restoration to curb biotic invasion—a practical guide

Common practices for invasive species control and management include physical, chemical, and biological approaches. The first two approaches have clear limitations and may lead to unintended (negative) consequences, unless carefully planned and implemented. For example, physical removal rarely completely eradicates the targeted invasive species and can cause disturbances that facilitate new invasi...

Exotic pet trade responsible for hundreds of invasive species around the globe

Last April, a male Burmese python led researchers at the Big Cypress National Preserve in the Florida Everglades straight to a 17-foot female that was carrying 73 developing eggs. The researchers had outfitted the male python with a radio transmitter, then let nature take its course. The male, of course, was on the hunt for […]...

White-tailed deer and an invasive shrub facilitate faster carbon cycling in a forest ecosystem

Publication date: 15 September 2019Source: Forest Ecology and Management, Volume 448Author(s): Michaela J. Woods, Elizabeth Roberson, Don Cipollini, Megan A. RúaAbstractForest soils sustain productivity and ecosystem function through nutrient cycling and by acting as a carbon stock. By retaining carbon, these soils delay its release into the atmosphere as a greenhouse gas. Forest disturbances may...

Uganda's Rare Tree Climbing Lions and Endangered Primates Threatened By Climate Change

KASESE, Uganda, Jun 12 2019 (IPS) - As climate change leads to increased temperatures in East Africa, a thicket of invasive thorny trees with the ability to withstand harsh climatic conditions have begun threatening Uganda's second-largest park, home to a rare breed of tree climbing lions and one of the highest concentrations of primates in the world....

Invasive Species Science Update (No

In this issue, we cover new research ranging from using chili powder to improve native plant restoration, searching for a link between exotic white pine blister rust and mountain pine beetle resistance in limber pine, identifying how melting arctic sea ice could open new pathways for invasive species introductions, and research into a relatively newly established biocontrol agent for rush skeleton...

7th IUFRO International Workshop on the Genetics of Tree-Parasite Interactions in Forestry Understanding forest tree-antagonistic interactions in a changing world

From 2020-09-21 to 2020-09-25, Pontevedra, Galicia, Spain, IUFRO Unit(s) involved: 2.02.15 Managed and natural forests provide essential ecosystem services worldwide. Due to the free of movement of people and goods across biogeographical zones, tree species are increasingly challenged by emergent invasive biotic threats. We can see large range expansions of pests and diseases, as well as sudden sh...

A decision support system for identifying potentially invasive and injurious freshwater fishes

An increasing threat to U.S. waterways is the establishment and spread of invasive and injurious fishes. A species may be designated by the U.S. Fish and Wildlife Service (USFWS) as federally “injurious” under the Lacey Act (18 U.S.C. 42) either if that species causes harm (injury) without establishing and spreading (not invasive), or if that species causes harm after establishment and spread ...

Fundamental host range of Trissolcus japonicus in Europe

Abstract The brown marmorated stink bug, Halyomorpha halys, native to East Asia, is an invasive alien pest that arrived in Europe in the early 2000s and poses an imminent threat to a wide variety of crops. Adventive populations of the Asian egg parasitoid Trissolcus japonicus, the most promising agent for classical biological control of H. halys, have recently been detected in It...

Modeling Pinus pinaster forest structure after a large wildfire using remote sensing data at high spatial resolution

Publication date: 15 August 2019Source: Forest Ecology and Management, Volume 446Author(s): José Manuel Fernández-Guisuraga, Susana Suárez-Seoane, Leonor CalvoAbstractIn the Mediterranean Basin, wildland fires are major drivers of forest ecosystem dynamics. In the current context of global change, these fires are becoming more severe and recurrent because of climatic conditions, land use change...

Invasive shrub cover and tree species composition influence exotic earthworms

Publication date: 1 September 2019Source: Forest Ecology and Management, Volume 447Author(s): Gwendolyn Lloyd, Michael B. Mahon, Thomas O. CristAbstractForest ecosystems are often invaded by multiple exotic species that, when combined, may amplify negative impacts on native biodiversity and ecosystem functioning. These patterns are often determined from plot-level experiments, but it is less clear...
