Tropical forests An insect could help farmers battle invasive cacti in Kenya (Biographic). The world owes the Democratic Republic of Congo more money to protect its forests, the country’s president says (Bloomberg). Deforestation in the Amazon continues, even as fires abate in the world’s largest rainforest (Gizmodo). Ghana appears ready to implement REDD+ to address […]...
The ‘European Red List of Trees’ assesses the conservation status of the 454 tree species native to Europe and finds that 42% of trees regionally are threatened with extinction. The assessment identifies invasive species, unsustainable logging and urban development as key threats to Europe’s tree species....
<p>The emerald ash borer (EAB) was first detected in North America in 2002, and since its introduction, this invasive pest has killed millions of ash trees. While EAB kills native North American ash trees in all settings, its impacts have been especially large in urban areas where ash has been a dominant street tree, especially in residential areas. While some management costs, such as insec...
Satellites have revolutionized forest monitoring, but there remains a major gap in biodiversity monitoring in forests since scientists can’t directly measure factors like hunting, sub-canopy fires, the impact of invasive animals, and light degradation very well from space. Bioacoustics — the use of sound recorders in nature — can help fill the gap. By capturing […]...
Hauptman T, Pavlin R, Grošelj P, Jurc MDISTRIBUTION AND ABUNDANCE OF THE ALIEN XYLOSANDRUS GERMANUS AND OTHER AMBROSIA BEETLES (COLEOPTERA: CURCULIONIDAE, SCOLYTINAE) IN DIFFERENT FOREST STANDS IN CENTRAL SLOVENIAAbstract: The East Asian ambrosia beetle (Xylosandrus germanus - Blandford 1894) is an invasive species that has become successfully established in Europe and North America. In Slovenia,...
Ash, elm and rowan among trees threatened by pests and pollution, says biodiversity reportMore than half of Europe’s endemic trees are threatened with extinction as invasive diseases, pests, pollution and urban development take a growing toll on the landscape, according to a study.Ash, elm and rowan trees are among those in decline, says the assessment of the continent’s biodiversity, which co...
<p>One of many ecosystem services essential to land management is carbon regulation, but presence of invasive species can influence carbon (C) in undesirable ways. Here we discuss early results of C accumulation from the Liko Nā Pilina hybrid wet forest restoration experiment. The focus of our project is to deliberately increase C storage through a functional trait-based approach to restora...
<p>Nonnative invasive herbivores can create complex biotic interactions by differentially feeding on native and nonnative invasive plant species. The herbivores may act as enemies of nonnative plants and prevent them from becoming invasive, or they may facilitate invasion by having a greater negative impact on native plants compared with nonnative plants. It is also possible that within the ...
The daily activities of mammals, reptiles, crustaceans, and fish influence the physical environment, with invasive burrowing species causing particular disruption in aquatic environments....
Invasive species have become an increasingly big threat to indigenous ones as the spread of alien animals and plants has accelerated with the growth of global trade. Some can be very destructive, while some live in close proximity without posing any sort of threat....
Background: Wildfire is an important ecological process in mixed conifer forests of the Intermountain West region of the USA. However, researchers and managers are concerned because climate warming has led to increased fire activity in recent decades. More area burned will result in larger land areas in early successional stages and will potentially limit tree establishment; therefore, evaluating ...
