Biodiversity loss is a global phenomenon. Driven by habitat degradation, climate change, the introduction of invasive species and other anthropogenically induced factors, around 1 million of the 8 million plant and animal species on earth are threatened with extinction. Increasingly, biodiversity loss is being recognised as a systemic risk with far-reaching consequences, including financial risks ...
The Madrid City Council has already started its plan to wipe out almost the entire population of Argentine and Kramer's parrots. During the next two years, 90% of the population of these invasive alien species will be reduced through the capture of specimens with the help of cages and nets as well as the sterilization of the eggs. The goal for 2023 is to leave only 10% of this population, which in...
Lionfish, an invasive species in the Atlantic and Caribbean Sea, is a threat to the marine ecosystem. Native to the Indo-Pacific, the lionfish devours over 80 types of prey who do not recognise it as a predator....
Knowing what species live in which parts of the world is critical to many fields of study, such as conservation biology and environmental monitoring.This is also how we can identify present or potential invasive and non-native pest species....
The time has come for an integrated strategy to manage our feral deer populations, according to the Victorian Forest Products Association. The call follows the release of the ABARES Pest and Weed Survey results, which shows that feral deer are a significant pest in north eastern Victoria and more widely across the state. Source: Timberbiz “The Victorian Government released its Feral Deer Control...
This issue highlights RMRS research spanning topics including using environmental DNA in fish eradication efforts, how bark beetle outbreaks affect weeds, long-term weed dynamics after forest restoration, the Fire Effects Information System’s invasive plant species database, uncovering the importance of seed-eating small mammals on plant communities and invasions, and others. We are also excited...
Forest age and species composition varies widely in the southern Appalachian Mountains, due to legacies of land use and disturbance such as repeat harvesting, fire exclusion, and invasive pests. In this highly productive region, leaf area recovers rapidly after harvesting (typically within five to ten years), while biomass accumulates more slowly (reaching peak basal area between 25 and 80 years)....
Native freshwater mussels grew more slowly when invasive Asian clams (Corbicula fluminea) were abundant. The study was led by Wendell Haag, an USDA Forest Service research fisheries biologist and published in the journal Freshwater Biology. Mussels live out of sight – buried in the river bottom, eating algae and other small particles of organic material. […]...
Scientists from Spain and Portugal have identified for the first time the 272 potentially invasive species in inland waters of both countries, which will allow the implementation of early warning and eradication systems to avoid ecological and economic damage....
The invasive ant world is a competitive one, rife with territorial battles and colony raids. And yellow crazy ants (Anoplolepis gracilipes), one of the world's worst invasive species, have an especially interesting trait: they're the only invasive ant known to have workers who can reproduce....
Kiwi are iconic birds that have been severely impacted by deforestation and predation from invasive mammals since the arrival of humans in New Zealand. The remaining kiwi can be split into 14 clusters that are now treated as separate conservation management units. A review published in Ibis examines the latest information on kiwi genetics to investigate the legitimacy for maintaining these differe...
The Asian longhorned beetle (Anoplophora glabripennis Motschulsky) (ALB) is an invasive polyphagous woodborer that has been introduced to North America and Europe. Due to the severe economic and ecological damage resulting from infestations of this insect, many countries, including the United States, have adopted policies of eradication. However, managing eradication can be a daunting cha...
