CABI scientists have helped map the ferocious speed and probable cause of a devastating spread of the invasive alien tree Prosopis juliflora (Swartz DC) across an area equivalent to half of neighbouring Djibouti in the Afar Region of north eastern Ethiopia....
China’s ambitious, multi-trillion-dollar Belt and Road Initiative could introduce alien invasive species into several countries, threatening their native biodiversity, warns a new study. Announced by Chinese President Xi Jinping in 2013, the Belt and Road Initiative (BRI), also known as “One Belt One Road” and “21st-century Maritime Silk Road,” proposes to connect China to countries [...
A new competition seeks ideas for tech solutions to a broad range of challenges facing conservation. The second round of the Con X Tech Prize encourages anyone to submit an idea for a new tool that could help resource managers, consumers, and decision-makers understand and address a conservation problem. Submissions are due March 13, 2019. […]...

WeisserAbstractLand-use intensification has been shown to negatively affect biodiversity and ecosystem functioning. Because higher trophic levels are expected to suffer most strongly from intensification, negative consequences for ecosystem services, such as bi...
Hemlock woolly adelgid, Adelges tsugae Annand, is an invasive insect species in eastern North America that was accidentally introduced from southern Japan. It is the single most important pest of hemlocks in eastern North America and has a severe impact on the two susceptible species: eastern hemlock, Tsuga canadensis (L.) Carriere (Pinales: Pinaceae) and Carolina hemlock, Tsuga caroliniana Engelm...
<p>Invasive pests and pathogens have contributed to widescale forest change around the world, but especially in the eastern US. Phytophthora cinnamomi, one such introduced pathogen, causes root rot in American chestnut (Castanea dentata) and shortleaf pine (Pinus echinata), among other eastern forest species of interest, and has inhibited chestnut restoration efforts in some cases. Tradition...
Ants (Formicidae: Hymenoptera) are important components of forest ecosystems and can be affected by fuel reduction forest management practices. We assessed the impact of repeated applications of fuel reduction treatments on abundance and diversity of ants within upland mixed-hardwood forests in the Southern Appalachian Mountains in North Carolina, USA. We established three replicate blocks (~56 ha...
For millennia, natural disturbance regimes, including anthropogenic fire and hunting practices, have led to forest regeneration patterns that created a diversity of forest lands across the USA. But dramatic changes in climates, invasive species, and human population, and land use have created novel disturbance regimes that are causing challenges to securing desired natural regeneration. Climate is...
