Increased global temperatures help invasive species establish themselves in ecosystems, new research led by a Swansea University bioscientist has shown.<\/p>\n


\n <\/section>\n

The study, published by the Royal Society, gives an insight into the probable combined effects of species invasions, which are becoming more common, and global warming.<\/p>\n

Climate warming and biological invasions result in the loss of species. They also alter the structure of ecosystems and the ways in which species interact.<\/p>\n

While there is already extensive research on how climate change and invasions affect species and ecosystems, we know surprisingly little about their combined effect, acting together in synergy.<\/p>\n

This is where the new study marks an important step forward. The work, funded by the EU Horizon program, involved Dr. Miguel Lurgi from the College of Science<\/a> working with colleagues from the Institut National de la Recherche Agronomique (INRAE) and the Centre National pour la Recherche Scientifique (CNRS) in France.<\/p>\n

The team used mathematical simulations to investigate how temperature influences invasions in complex food webs comprised of 30 species. They paid particular attention to the combined\u2014synergistic\u2014effects.<\/p>\n

The aim was to provide a theoretical model for how ecological communities are likely to respond to the joint effects of warming and invasions.<\/p>\n

The model accounted for factors such as reproduction and death rates, average species body size, and interactions between species\u2014such as predators attacking prey.<\/p>\n

The team simulated what happ<\/a>ens when an alien species is introduced into an ecosystem. They then ran the simulation forward in time using 40 different temperature values from 0 to 40 degrees Celsius.<\/p>\n

This allowed them to model the combined effects on the ecosystem of temperature rises and of the new species being introduced.<\/p>\n

They analyzed the simulation results to assess the effects of temperature on food web properties before invasion, invasion success, and the effects of invasions on community structure and stability.<\/p>\n

They found:<\/p>\n
