A new study shows that iguanos could be the biggest threat to Australia’s wildlife by 2050.
The research, by researchers from the University of Queensland, found that an increase in the number of desert igus in Australia’s west coast could make it difficult for native reptiles such as the brown snake and desert tortoise to survive.
It also found that habitat fragmentation could result in the decline of some species.
Key points:The research found that desert iguas could be one of the biggest threats to Australia by 2050The study found that fragmentation of desert habitat could make desert igua populations more vulnerable to predatorsThe study also found an increased number of iguanis in the west coast of Australia could lead to habitat fragmentation, which could in turn make the animals more vulnerable.
The findings were published in the journal Nature Communications.
The study focused on the eastern side of the Great Australian Desert (GAAD), which includes the central Great Basin and surrounding areas.
“If the current population of iguana numbers are to stay stable, it will be critical for desert igugans to maintain a stable number of individuals,” said lead author Dr Rachel Brown.
“That’s because we know that once we lose habitat, we lose all our animals.”
Dr Brown said she wanted to find out why the desert tortoises and desert iguelas were declining.
“The most obvious explanation is habitat fragmentation.
When people move into an area and they don’t have enough habitat to keep all the animals in the area, then they can be susceptible to desert iguuas.”
They’re more likely to get hit by cars or get shot by dogs or anything that can hurt them,” she said.”
It’s a bit like the car accident in Australia.
“Dr Lisa Hickey, from the Australian Institute of Marine Science, said desert igurans are important for the survival of the desert turtle and other desert species.”
We have seen in the past that a decline in the population of the turtle is one of many causes for the decline in other marine species, so it’s important to recognise that they’re also a great threat to the iguana,” she told the ABC.”
So if we want to save them, we need to find other sources of habitat for them.
“Dr Hickey said the study found the desert is vulnerable to habitat change.”
For example, if you take a group of desert tortuas from a place where there was never much land, you can see that in the northern desert that they were migrating into new areas that were very different from the ones they used to occupy,” she explained.”
There’s lots of habitat that the tortoias were dependent on.
“The study did find that the number and type of animals that were moving into new environments had an effect on the density of desert animals.”
In other words, the more they were moving, the denser they were, and the more animals that could potentially make it through that dense environment,” Dr Hickey explained.
However, the authors said there was no way to predict how the effects of habitat change would change.
Dr Brown agreed.”
Unfortunately, there’s no way of knowing that habitat change will make it any worse for the iguanita population, because we don’t know the extent of the population changes that occur,” she concluded.
