Invasive species have diverse impacts in different locations, including biodiversity loss, as a result of native species being outcompeted for similar resources. A US research team studied the case of an aggressive Eurasian woodwasp that has recently established in North America and poses a threat to a native competitor species. In their paper, published in the open-access journal Neobiota, the scientists seek a solution for the seemingly rapid decline in the native wood-boring insect.
Mining on the ocean floor could do irreversible damage to deep-sea ecosystems, says a new study of seabed mining proposals around the world.
Facing a climate crisis, we may someday spray sulfur dioxide into the upper atmosphere to form a cloud that cools the Earth, but suddenly stopping the spraying would have a severe global impact on animals and plants, according to the first study on the potential biological impacts of geoengineering, or climate intervention.
The Joint Research Centre (JRC), the European Commission's science and knowledge service, has measured progress and shortfalls in the connectivity of protected areas in countries across the world, identifying the main priorities to sustain or improve connectivity in each country.
An international review led by the University of Queensland and WCS (Wildlife Conservation Society) says that many native carnivores that live in and around human habitation are declining at an unprecedented rate - spelling bad news for humans who indirectly rely on them for a variety of beneficial services.
Post-fire logging, rather than the wildfires themselves, is responsible for the steep decline in territory occupancy of the rare spotted owls living in the forests of California. The study's results coincide with the strong consensus among hundreds of US scientists opposing post-fire logging operations due to a wide range of ecological harms. The research is published in the open-access journal Nature Conservation.
Animal carnivores living in and around human habitation are declining at an unprecedented rate -- but they may provide crucial benefits to human societies. An international review led by University of Queensland researchers has revealed that predators and scavengers ranging from bats to leopards and vultures are valuable to human health and well-being.
Can tumors teach us about animal evolution on Earth? Researchers believe so and now present a novel hypothesis of why animal diversity increased dramatically on Earth about half a billion years ago. A biological innovation may have been key.
What lives in your dirt? University of Colorado Boulder researchers are one step closer to finding out after compiling the first global atlas of soil bacterial communities and identifying a group of around 500 key species that are both common and abundant worldwide.
In Science, 30 experts with the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) advocate consideration of a fuller, more comprehensive range of 'nature's contributions to people' in policy- and decision-making. Says IPBES Chair Sir Robert Watson: 'This new inclusive framework demonstrates that while nature provides a bounty of essential goods and services, such as food, flood protection and many more, it also has rich social, cultural, spiritual and religious significance -- which needs to be valued in policymaking as well.'
