Invasive species could reap benefits from extreme weather

Extreme weather might be wreaking havoc across the globe, but some non-native plants and animals could be benefiting from the disasters, adding risk to already threatened local species, according to a new study Monday.

Invasive species, often transported by human activity, are thought to be playing a major role in global extinction rates and the catastrophic declines of biodiversity threatening the well-being of people and planet.

Heatwaves, droughts, floods and other extremes accelerated by global warming might be giving the often destructive invasive species an undesirable advantage, researchers found.

The harmful invaders experienced positive impacts from extreme weather almost a quarter of the time, nearly double that of natives, according to the study published in Nature Ecology & Evolution.

Local species were also more likely to suffer negative consequences from the weather disasters.

"EWEs (extreme weather events) might facilitate the establishment and/or spread of non-native species and these two processes may combine together to pose high threats to biodiversity under continuing global change," lead author Xuan Liu of the Chinese Academy of Sciences in Beijing, told AFP.

Invasive species were only vulnerable to heatwaves and storms, the study found.

But native animals on land and in fresh water were negatively impacted across several factors -- including survival rates, reproduction and body size -- from all extreme weather except cold spells in freshwater.

The researchers looked at hundreds of previously-published studies on responses of 187 non-native and 1,852 native animal species to extreme weather patterns in different habitats.

They found that differences in responses to unusual weather in species could be due to the death of native species during weather extremes, leaving a gap for invasive species to exploit.

Severe droughts, for example, increase the salt content of water, killing local invertebrates and fish while providing an opportunity for more salt-tolerant species to move in.

Invasive species are also known for rapid growth rates and a greater competitive edge that might allow them to recolonise faster.

Only in the case of marine animals were both natives and non-natives relatively immune to extreme weather -- although native molluscs and corals are vulnerable to heat waves.

Invasive species are not a new problem, but they are growing one.

The intergovernmental science advisory panel for the UN Convention on Biodiversity (IPBES) revealed in a landmark report in September that invasive species were increasing at an "unprecedented rate" globally, costing more than $400 billion dollars a year in damages and lost income.

Invasive species mainly spread as hitchhikers on global trade and played a significant role in 60 percent of all documented plant or animal extinctions, it said.

Scientists weigh in on what happens when cats get fat
Urbana IL (SPX) Nov 02, 2023
Cat owners want Kitty to be happy, but providing an abundance of food and snacks can have unintended consequences. Feline obesity is on the rise, impacting the health, longevity, and wellbeing of cats. A new study from the University of Illinois Urbana-Champaign looks at what happens in the digestive system and gut microbiota when cats eat too much. "About 60% of cats in the U.S. are overweight, which can lead to health problems such as diabetes and chronic inflammation. While many studies have in ... read more
