Uncovering Urban Forests

The scope of forest-pest risk analysis research is often limited to natural forests. Neglected are those tree communities called urban forests: trees within the boundaries of a city or populated area. Urban trees see a significant proportion of the impacts from invasive pests. Their unnatural distribution and close proximity to transported goods and other means […]...

Asian longhorned beetle larvae eat plant tissues that their parents cannot

Despite the buzz in recent years about other invasive insects that pose an even larger threat to agriculture and trees -- such as the spotted lanternfly, the stink bug and the emerald ash borer -- Penn State researchers have continued to study another damaging pest, the Asian longhorned beetle....

DNA tests of UK waters could help catch invasive species early

A team of scientists from the University of Southampton, Bangor University and the National Oceanography Centre have discovered several artificially introduced species in the coastal waters of southern England, using a technique that could help the early detection of non-native species if adopted more widely....

OPINION: Harmful invasive species are on the move, we need a global alliance to stop them

There has been a baffling absence of an international alliance to track and respond to the movement of invasive species...

Demonstrating the potential of a novel spider venom-based biopesticide for target-specific control of the small hive beetle, a serious pest of the European honeybee

Abstract The parasitic small hive beetle (Aethina tumida) feeds on pollen, honey and brood of the European honey bee (Apis mellifera); establishment in North America and Australia has resulted in severe economic damage to the apiculture industry. We report potential for the “in-hive” use of a novel biopesticide that is toxic to this invasive beetle pest but harmless to honeyb...

Promise and pitfalls of endemic resistance for cultural resources threatened by Phytophthora ramorum

<p>Invasive forest pathogens can harm cultural, economic, and ecological resources. Here, we demonstrate the potential of endemic tree pathogen resistance in forest disease management using Phytophthora ramorum, cause of sudden oak death, in the context of management of tanoak (Notholithocarpus densiflorus), an ecologically unique and highly valued tree within Native American communities of ...

Seedling survival of Prunus serotina Ehrh., Quercus rubra L. and Robinia pseudoacacia L. in temperate forests of Western Poland

Publication date: 15 October 2019Source: Forest Ecology and Management, Volume 450Author(s): Marcin K. Dyderski, Andrzej M. JagodzińskiAbstractAlthough invasive trees species spread effectively across different habitats, data on survival of their seedlings are scarce. We compared seedling survival after the first year from germination for the three most invasive tree species in temperate Europe. ...

Picky pathogens help non-native tree species invade

Trees have many natural enemies, including pathogens that have evolved to attack certain tree species. Invasive tree species -- even ones that are very closely related to native trees -- are often not attacked by these pathogens and can thrive....

Competition and tolerance of low soil water favor Carex dominance over establishing Acer seedlings in managed temperate mesic forests

Publication date: 1 October 2019Source: Forest Ecology and Management, Volume 449Author(s): J.A. Randall, M.B. WaltersAbstractCarex pensylvanica (Pennsylvania sedge) dominance of managed temperate mesic forest understories is associated with high deer browsing pressure, frequent partial timber harvests, invasive earthworms, and low seedling-to-sapling recruitment rates of canopy-dominant Acer sacc...
