After a more than a century of fighting to keep fire out of forests, reintroducing it is now an important management goal. Yet changes over the past century have left prescribed burning with a big job to do. Development, wildfire suppression, rising global temperatures, extended droughts, exotic species invasions, and longer fire seasons add complexity to using this practice.<br><br>Ma...
Forested black ash (Fraxinus nigra) wetlands are an important economic, cultural, and ecological resource in the northern Great Lake States, USA, and are threatened by the invasive insect, emerald ash borer (Agrilus planipennis Fairmmaire [EAB]). These wetlands are likely to experience higher water tables and warmer temperatures if they are impacted by large-scale ash mortality and other global ch...
As invasive species continue to thrive, the eco-community stands divided on how best to build healthy ecosystems around it. For many of us, Eucalyptus trees have always been a part of the Indian landscape. They were the primary markers of hill stations, signalling the transition from plains to higher ground....
The walnut twig beetle, Pityophthorus juglandis Blackman (Coleoptera: Scolytidae), vectors the fungus Geosmithia morbida, which has been implicated in thousand cankers disease of walnut. Little is known about the flight behavior of the insect across seasons, or about the variability in its flight patterns with weekly fluctuations in weather. We sampled flying adults week...
Remediation of soil contaminated by heavy metals has become a hot topic in the world, and phytoremediation technology is the most widely used. Compared with physical and chemical remediation, phytoremediation technology has the advantages of high cost-effectiveness, in-situ application, less invasive, less destructive and so on....
Abstract Beer is prone to flavor changes during aging that influence consumer acceptance within shelf life. The shelf life of beer is defined as the period over which flavor changes remain acceptable. Assessment of flavor changes caused by volatiles is typically achieved with a combination of sensory evaluation and gas chromatography–mass spectrometry (GC–MS). Volatile indica...

Invasions by non-native pests and diseases represent serious threats to biodiversity, agriculture and human health. Under current border arrival rates associated with international trade not all such invasions can be prevented, so early detection and eradication (forced extinction) are important strategies for preventing establishment and long-term impacts. Removal of host plants has historically ...
Global ecosystem functions, services, and commodities are increasingly threatened by biological invasions. As a result, there is an urgent need to manage invasive species through global collaborative research. We propose an 'applied empirical framework' (AEF) to aggressively confront the current global biological invasion crisis. The AEF builds on existing models for invasion science tha...
The Illegal trade in wildlife is a massive, multibillion-dollar market driven by international criminal networks and exacerbated by a nexus of poverty and corruption. Wildlife trade is a crime that, when combined with other threats like habitat loss and climate change, can drive thousands of species to the brink of extinction, lead to ecosystem breakdown and spread invasive species....
The red squirrel is the UK's only native squirrel species. Unfortunately, they are now a very rare sight across Britain and Ireland, thanks to widespread destruction of their native forests, combined with competition from the larger grey squirrel - an invasive species introduced from North America. It's also due to the spread of diseases such as the squirrelpox virus, which causes ulcers and scabs...
