COLOMBO — Located in the suburbs of Sri Lanka’s biggest city, Colombo, the picturesque Thalangama Lake is plagued by at least two invasive predatory fish species that are contributing to the decline of the native aquatic life. “I have heard villagers living close to the lake claiming that they had seen a fish with a […]...
Invasive plants have the potential to affect decomposition both directly, by introducing novel substrates that may differ from native species in key structural or chemical properties, and indirectly through changes to soil properties and microbial communities. The relative importance of these two mechanisms is unclear, especially with regard to wood decomposition. To explore these questions, we us...
Chinese privet (Ligustrum sinense Lour.), is known to negatively affect biodiversity near the ground in invaded forests by forming thick layers of non-native vegetation in the midstory. Whether these effects extend above the shrub layer into the canopy remains unclear. We sought to test this question by using flight-intercept traps (clear plastic panels attached to a white bucket) to sample bees a...
In many ways, biodiversity is a foundational component of healthy, productive forests and maintenance of the many ecosystem services that they provide (e.g., carbon sequestration, nutrient cycling, water filtration and provisioning, wildlife habitat). Forested landscapes are often characterized by a mosaic of species, age classes, and structural characteristics that results from natural patterns o...
Deforestation, rising temperatures, drought, fire and other ecological disturbances are reducing forest cover on much of the earth, and compromising the ability of forests to supply important ecosystem services. Ecosystem management and ecological restoration are focused on preventing and repairing ecosystem degradation, but the rapidity and pervasiveness of these global transformations threaten t...
The Forest Health Monitoring (FHM) national program of the U.S. Department of Agriculture Forest Service determines status, changes, and trends in indicators of forest condition across all forested lands (ch. 1). One of the central objectives of the FHM annual national reports is to present forest health indicator information from a national perspective, or from a multi-State regional perspective ...

Logging activities and its associated infrastructure are potential pathways for invasive forest plants, yet little is known about logger activities regarding invasive plants during logging operations. Logging business owners in Minnesota, USA were surveyed about invasive forest plants as a case study to learn about their awareness, interactions with landowners and land managers, actions to control...
Breeding programs are an important tool for managing invasive insects and diseases causing high mortality rates and even threatening extinction of some of our forest tree species. The emerald ash borer (EAB) invasion of North America, as one example, has resulted in five North American ash species being listed as "critically endangered" on the IUCN red list (IUCNredlist.org). Impacts fro...
Before weed biocontrol insects are transported and released in a new area, they are commonly collected into small paper containers, chilled, and kept under dark conditions. This process can be termed a pre-release protocol. The influence of a prerelease protocol on establishment success of a gregarious biological control agent was assessed using the northern tamarisk beetle, Diorhabda carinulata (...

DAHLIAE: NEW OUTBREAKS FROM TUSCANYAbstract: Verticillium spp., including V. nonalfalfae and V. dahliae, are known vascular wilt pathogens of the invasive Ailanthus altissima (tree-of-heaven) in the United States and in Europe. Herein we provide ...
