Gee wonder what the Sceptics will say about that one Magoo... Nice find... :Y:

Wish 'climate change' would take out feliscatus... 1 million native wildlife killed every night by Feral Cats... :N:

In short drowning.
I remember seeing it on TV a couple of years ago.

Thats an underestimate LW , with scientific estimates of there being upto 13 million feral cats in Australia , the number of animals killed each night would be at least that figure or more . Dont forget a natural behaviour of cats is also practice killing or hunting . Felixer cat traps are a descent solution to the problem of cats and foxes as is gene drive technology.

That reduction of the dinosaurs way back only left the terrasaurs...... guess they were the only ones able to hop the tidal waves rebounding around the earth after the ocean was struck by a comet..... would'a been a bugga doing that in the dark of night, but I spose you'd a heard it comin at any rate.... not sure what the technical name for that particular extinction event was.

Think that was the 3rd mass extinction event Silver but dont quote me on that .
Yes you are correct Danny, my figures are way short, this was discussed last year in another topic on feral Cats..... I read the other day the Foxes are starting to feast on the Cats now... Wish foxes would come to my place and feast on the roaming cats around here... They do make good crab bait tho... so I have been told...

Looks exactly the same as the ones in my shed :lol:Mr Magoo said:
I think it was a stoning! :8silver said:
The Bramble Cay melomys . was a small rodent restricted to a 5ha uninhabited island in Torres Strait .... The primary ecological cause of its extinction was not resolved, but it was most likely due to one or more storm surges leading to brief inundation of its lowlying island home (Gynther et al. 2016)."Goldfreak said:So how did climate change kill them off ?

"Records indicate that numbers of birds and rats have declined over the last century, possibly due to erosion and loss of vegetated area of the cay".
So basically a population of a few hundred rats distributed over only 5 ha (some reports say 3.6 ha) of the Earth, at very close to sea level. At high tide the exposed area of the island was 251 x 104m. It was mined for phosphate rock in the 1860s.
Storm surges will increasingly affect tiny islands like this that are barely above sea level, as sea level rises, so I guess this is why they relate its extinction to be due to climate change (as has now been claimed). Of course it could have been one tiny tsunami, who knows? But even if this was not due to sea level rise, sea level rise will undoubtedly cause extinctions on such tiny islands in the future.
Hard to form an opinion about this either way. Science should resolve this, perhaps the body of evidence is too huge for my tiny mammalian brain to process :awful: as for cats I have a love hate relationship with them. I miss having them around and the kids would love one but then we wouldn't have these guys in our garden
the duck has since had lots of ducklings. Cute but am getting sick of them crapping on our veranda. Shot a big fox recently too, beautiful animal but very destructive.

Goldfreak, science already has the solutions to climate change - its people (polititions etc) that need to change .
silver said:Just wait till the solar system plunges through a hydrogen cloud in space.... probably the very space around us will be aglow with light..... and it may well just rain for 40 days and nights.... or more. Afterwards as the atmosphere adjusts and we cast off that which we cannot hold and the waters receed we may well be only a few waterlogged specimens to start anew. Be plenty of light at the poles on the way through the space cloud though hey !
wonder how good they are at seeing space clouds... or would we just see straight through em.... bugga's get a fright when they spot a new near earth object ..... who's gunna spot a little blobby cloud out beyond the solar systems reach
The solar system is currently passing through a galactic dust cloud and yes they are detectable.

Good day Goldierocks - the Bramble cay Melomys is the first mammal in Australia to go extinct probably due to climate change induced factors. The second mammal is most likely the white Daintree River Ringtail Possum . It lives at high altitudes where temperatures are below 29 degrees. The heatwave recently had temperatures at those mountain top elevations at 39 degrees. Anything above 29 degrees and the possums die as they dont have the ability to heat regulate or sweat. None have been seen since that event a few months ago.

Yes, I imagine there might be a few other high altitude marsupials in imminent danger (I seem to recall a pygmy glider in Victoria). It is difficult to know if some of these things would have survived even without human climatic intervention (the Melomys seems to have occupied an extremely local and restricted habitat). However given that any further warming would have only been very gradual, I imagine that things like the possum you mention might have simply evolved into something that could cope with warmer conditions. Species come and go, but in the past they had time to evolve and adapt in many cases. I imagine there is much debate among zoologists and botanists as to which species we should spend money on preserving and which we should let fade away - obviously we cant save everything.
