Native species in California's estuaries are expected to experience greater declines as invasive species interact with climate change, according to a study from the University of California, Davis. The study "Biological Invasions Alter Consumer-stress Relationships Along an Estuarine Gradient," published in the Ecological Society of America's journal, Ecology, said these declines are expected not only because of climate-related stressors, but also because of the expanding influence of new invasive predators whose impacts are occurring much farther up the estuary.

This book is part of the CABI Invasive Series, which addresses all topics relating to invasive species, including biosecurity surveillance, mapping and modelling, economics of invasive species and species interactions in plant invasions. This book specifically aims to examine the nexus of climate change and biological invasions, and the resulting impacts, and to identify means to reduce the vulnerability and increase the resiliency of managed and unmanaged ecosystems.

A desire to avoid more extinctions is one of the drivers behind new research by the Threatened Species Recovery Hub which has identified invasive species as the no. 1 threat to Australian biodiversity with habitat loss a close second.

Protecting ecosystems from degradation caused by invasive species can help protect species at risk and critical habitats. In 2019, the United Nations reported invasive alien species as a top-5 driver of species decline.

The Mediterranean Sea is being invaded by hundreds of fish, jellyfish, prawns and other marine species from outside the region. More than 1 000 non-indigenous species have been identified in the Mediterranean and the Black Sea. Over half have established permanent populations and are spreading, causing concern about the threat they pose to marine ecosystems and local fishing communities.

“Climate change and human activities have had a profound impact on the Mediterranean and the Black Sea,” says Stefano Lelli, a fishery expert for the eastern Mediterranean working for the General Fisheries Commission for the Mediterranean (GFCM). This regional fisheries management body, established by FAO, is leading efforts to promote sustainable fisheries and aquaculture in the Mediterranean and the Black Sea.

A new botanical survey of southwest Ohio found that invasive species introduced to the United States over the past century are crowding out many native plants. Biologists from the University of Cincinnati are retracing two exhaustive surveys conducted 100 years apart to see how the Queen City's plant diversity has changed over the past two centuries. They focused their attention on undeveloped parts of cemeteries, banks of the Mill Creek and public parks that have remained protected from development during the last 200 years. The study, titled "The rise of nonnative plants in wooded natural areas in southwestern Ohio," was published in June in the journal Ecological Restoration.

Pressures from climate change are exacerbating the challenges of human activity on Antarctica, as climate change is bringing milder conditions to these wildlife-rich areas, both on land and sea. As glaciers melt, new areas are exposed, which allows non-Antarctic species greater opportunity to establish and possibly outcompete locals for resources, such as nutrients and precious, ice-free space.
