Balancing Impacts of Range-shifting Species: Invasive Disruption vs. Biodiversity Benefits

Climate change will cause species to shift their ranges to survive. Although the impacts of range-shifting species can vary from minor to massive, considerations of species movements in the context of climate change has almost entirely focused on positive impacts. This Review uses invasion ecology theory to consider the impacts of shifting species and how to manage these shifts to protect the recipient communities as well as the survival of the shifters. As Earth's climate rapidly changes, species range shifts are considered key to species persistence. However, some range-shifting species will alter community structure and ecosystem processes. Communities are unlikely to shift as a whole, and partial shifts will disrupt species interactions and lead to trophic mismatches. Rather than developing new strategies to evaluate the potential impacts of range-shifting species, invasion ecology theory and risk assessment tools can be used to quantify the magnitude of the potential impacts of range shifters and define specific conservation goals in response. By adapting existing invasion risk assessment frameworks, characteristics shared with highimpact introductions can be identified and thus predict potential impacts. This will allow us to maintain biodiversity and ecosystem functioning most effectively despite a rapidly changing climate. There are fundamental differences between introduced and range-shifting species, primarily shared evolutionary histories between range shifters and their new community. Nevertheless, impacts can occur via analogous mechanisms, such as wide dispersal, community disturbance and low biotic resistance. As ranges shift in response to climate change, plans to facilitate advantageous movements and limit those that are problematic can be developed. However, both researchers and managers will likely need to adopt a more fluid and dynamic view of what constitutes a community, as differences in species' responses could result in communities with no current analogue. informacion[at]ebd.csic.es: Wallingford et al (2020) Adjusting the lens of invasion biology to anticipate impacts of climate-driven range shifts.

Eucalypt plantations disturb the development of amphibian larvae

Consequences of human actions like global warming, spread of exotic species or resource consumption are pushing species to extinction. Even species considered to be at low extinction risk often...

Identifying the most threatened areas by human activity in the Mediterranean Sea

A study analysed and distributed the existing information on several impacts that are simultaneously affecting the Mediterranean Sea: from climate impacts like the rise of temperatures in the sea,...

Understanding resident and migratory bird populations responses to climate warming

Many organisms adjust their reproductive phenology in response to climate change, but phenological sensitivity to temperature may vary between species. For example, resident and migratory birds...

Different responses to climate change in resident and migratory birds

The adjustment to climate change and the differential effects of temperature on resident and migratory birds were studied using the start dates of the laying in ten long-term studies in nest-boxes...
