Claim: Global Warming killed a Species of Rat

Guest essay by Eric Worrall

Claims are flying that Global Warming has claimed its first mammal, a kind of rat which used to live on just one small island in the Cyclone prone Torres Strait, off the Northern coast of Australia.

Human-caused climate change appears to have driven the Great Barrier Reef’s only endemic mammal species into the history books, with the Bramble Cay melomys, a small rodent that lives on a tiny island in the eastern Torres Strait, being completely wiped-out from its only known location.

It is also the first recorded extinction of a mammal anywhere in the world thought to be primarily due to human-caused climate change.

An expert says this extinction is likely just the tip of the iceberg, with climate change exerting increasing pressures on species everywhere.

The rodent, also called the mosaic-tailed rat, was only known to live on Bramble Cay a small coral cay, just 340m long and 150m wide off the north coast of Queensland, Australia, which sits at most 3m above sea level.

It had the most isolated and restricted range of any Australian mammal, and was considered the only mammal species endemic to the Great Barrier Reef.

When its existence was first recorded by Europeans in 1845, it was seen in high density on the island, with sailors reporting they shot the “large rats” with bows and arrows. In 1978, it was estimated there were several hundred on the small island.

But the melomys were last seen in 2009, and after an extensive search for the animal in 2014, a report has recommended its status be changed from “endangered” to “extinct”.

Calling the dead rats a victim of “climate” seems a bit of a stretch. A small population species which precariously clings to existence on a tiny spit of low lying land in the middle of Australia’s Cyclone Alley was never destined to survive for long.

From the Australian Government Website;

There are three threats to the species. Firstly, there is only the single known population of the species and searches on other cays and in adjacent areas of New Guinea have failed to discover other populations. Secondly, the cay is prone to inundation from storm surge and other disturbances. Further compounding risk to the species is that the species appears to be inbred. Therefore, resilience of the species to catastrophic events such as cyclones, introductions of weeds or introduced predators, or the arrival of a novel disease, is very low (Curtis et al. 2012 cited in DEHP 2013e).

The most recent survey for the species in 2012 resulted in no animals being recorded. The most recent verified record of the species is from trapping in 2004. It is possible that a catastrophic inundation of the island has already occurred (DEHP 2013e).

Well clearly these Melanomas are not native to that island, or we would find fossils of their ancestors that they evolved from. So they are or were an invasive species, so good to get rid of.
And if they WERE the wildlife, then they must have been cannibals, if there was nothing else that they ate. Cannibalism is not known for its survival characteristics. Sooner or later you run out of friends to eat.

Yeah, they claim that sea level rise is the cause, but in this article from 2013 it was mentioned that the place rose in size between 1987 and 2011. This would seem quite difficult if the sea level had risen there, wouldn’t it.

But hey, why bother with little details like that? We must not interrupt them while they are busy shaming and blaming, and wringing their hands, because of course, “this is just the tip of the iceberg”. Yes.

Did the target practice in the 1800’s have anything to do with the ultimate extinction? Or was the isolation of the species the event that led to the inevitable conclusion? The article points to no mechanism whereby human caused global warming has impacted the demise of this creature. And it still remains possible that there will be other members of this species found at some other point in the future. After all, we don’t even really know if they were a distinct “species” at all since there was no opportunity to determine if they could mate with other rats, which I suspect that they most likely could, meaning that the designation as a “species” is only for the pride of some rodentologist. How do we test whether any of these “species” is in fact distinct and cannot mate with others? That’s the fraud of “Darwin’s Finches”–they were not distinct species at all, but members of the same species.

The CAGW inference goes like this.
(1) the island was already prone to inundation
(2) the seas are rising and we’re all gunna DROWN!
(3) we don’t actually know for sure that these creatures are all gone, or if they are gone, what did them in, but it MUST be our fault and we’re all gunna DROWN
(4) so the Bramble Cay melomys must have been wiped out by the accelerated sea level rise that is going to DROWN US ALL.
So that’s the mechanism they have in mind.
All it would take is one ship tying up — which they do — and a a couple of dogs let loose on the island for a couple of days, and no more Melomys.

From 2013:”Threats
The small population size means genetic drift, disease and introduced species all pose a threat to the species.
Habitat loss via erosion of the cay is the single most important threat, particularly given that sea levels are predicted to rise thanks to climate change. Bramble Cay is by no means stable. Between 1958 and 1987, the cay decreased in size; but in 2011 it had returned to a size comparable to 1958.
While the size of the cay varies, the vegetation on it is shrinking, and this might be the main cause of the melomys’ decline.
Bramble Cay also serves as a rookery to marine turtles and seabirds. The vegetation is disturbed by nesting seabirds throughout the year and by turtles between October and March. In our December 2011 survey the area disturbed by turtles was quite extensive, and many turtles were nesting towards the centre of the cay. Photos show a substantial reduction in the cover of vegetation between 2009 and 2011.”

Turtles are carnivores, I believe. I suspect the turtles could have caught the occasional rat here and there, slowly depleting the slender numbers of the tiny species (if, indeed, it was a species). Further, seabirds (which eat about anything) could easily have snarfed down some teensy weensy baby rats (“Ooh!” gulp “That was good! Here’s another!” gulp etc.); nor does the article state which seabirds were there, though hardly any that I know of are herbivorous. It does not require mankind to deplete wildlife in an isolated area (which an island is, by definition). There is no known cure for stupidity.

Also, rats can swim and tread water for days. So it’s possible that some Melomy refugees have washed up on other nearby islands. If predatory fish didn’t get to them first–they’re not that picky about what they eat. If it fits in their mouths, it’s fair game.

Barrier Reef rodent is first mammal declared extinct due to climate change
The Bramble Cay melomys 14 June 2016

“A thorough survey effort involving 900 small animal trap-nights, 60 camera trap-nights and two hours of active daytime searches produced no records of the species, confirming that the only known population of this rodent is now extinct.”
“Anecdotal information obtained from a professional fisherman who visited Bramble Cay annually for the past 10 years suggested that the last known sighting of the Bramble Cay melomys was made in late 2009.”
Dr Leung said the fact that exhaustive efforts had failed to record the rodent at its only known location and extensive surveys had not found it on any other Torres Strait or Great Barrier Reef island gave him confidence in the assertion that Australia had lost another mammal species.
“Significantly, this probably represents the first recorded mammalian extinction due to anthropogenic climate change.
“However, new information is provided in support of a previously presented hypothesis that the Fly River delta of Papua New Guinea is a possible source of the original melomys population on Bramble Cay, so the Bramble Cay melomys or a closely related species might occur there. “
Dr Leung said it could be premature to declare the Bramble Cay melomys extinct on a global scale.
The study was led by Ian Gynther from Queensland’s Department of Environment and Heritage Protection and in partnership with UQ researchers Natalie Waller and Luke Leung.

I haven’t been able to find anything on how far the “island” is from the mainland.
Perhaps it was easier to reach during the last ice age.
Regardless, rodents are famous for hitching rides on pieces of drift wood and being carried to nearby islands.

Reply to  Mike Jonas
June 15, 2016 5:16 pm

Obviously the island was connected to the mainland ~10k years ago. The island is also in range of driftwood from the Fly River, PNG. So the colony has been isolated for ~10k years max and possibly a lot less. It might even have come and gone multiple times over the millenia (in on driftwood, breed up, wiped out by a storm surge, rinse and repeat). ]Walked in seems more likely than the driftwood route, if there’s no known colony elsewhere.]

And Richard says there are Melomys all over the place, so what is this rubbish about them being extinct ? Either there ARE melomys elsewhere that could have been introduced to this rock pile, and live there a while, or else there aren’t any anywhere else. Just round up some from elsewhere and take them to this piece of sand during the next low tide, when it is above water. Well they will drown too come high tide, but at least they will have lived on their new species digs for a few hours.

Leonard, Melomys are a separate family to rats. Around the Brisbane area there are two types of Melomys – Melomys cervinipas (fawn footed) and Melomys burtoni (grassland). There are five types of the family rattus- rattus fuscipes (bush rat), rattus lutreolus (swamp rat), rattus tunneyi (pale field rat), rattus rattus (ship rat which came from suth-east Asia on ships) and rattus norvegicus (sewer rat which came from Europe in ship cargo). The Melomys are quite cute. They are nocturnal and good climbers in rainforest trees and mangroves. The first three types of rats mentioned are indigenous Australian rats that do not come near housing. The sewer rat and ship rat are not nice. They are the ones that are the scavengers and get into housing and rubbish dumps etc. and can carry disease.

Nice reply cementafriend – I’d like to add to that from my experience trapping rats and small marsupials for surveys that our native bush rats are charming little things and I’ve often wondered why we persist with the raising of rattus and norvegicus in Oz for pets and research when we’ve these little guys to work with instead. R. fuscipes was always a hoot – after releasing one you’d just caught and inspected they’d d wait at your feet for you to bait and set the humane trap so they could skip back in for the free lunch again.(trap happy we called it) and so you’d have to shoo him off and set the trap elsewhere.

So Karl, if you and enough other curiosity seekers keep on trapping the little critters so you can study them, pretty soon you too will have all of them in your museum drawers, so future generations of museum goers can see what they were like before you all extincted them.
You could try using a digital SLR camera to take pictures of them outside of your traps where they belong.

Well colour me confused.. I said I released them.. The trapping was for ag department and WA museum range distribution and population surveys, they were weighed, measure, given a dot of colour and released.. Not that they seemed keen or release, but whether or not they liked it they were sent packing. My comment was about the fact they were so friendly that resetting the trap in the same location only resulted in the same rats being caught over and over again. Was I that unclear?
PS DSLR’s were about 20 years away from being invented at the time I was doing this, though I have some film images of various R. fucipes hugging my assistant (and some others of Antechinu sp. mauling thumbs and trying to drag their human prey off into the undergrowth).

From Wiki:
The 3.62-hectare (8.9-acre) sand cay is predominately grassland, with 1.72 hectares (4.3 acres) covered in grasses.
From their article on the rat:
Australia’s most isolated mammal, the Bramble Cay melomys was known only from a small population in Bramble Cay, a vegetated coral cay of 340 by 150 metres (1,120 ft × 490 ft).
Bramble Cay is a football field sized chunk of land sticking out of the ocean. The rat’s probably drowned in a storm. End of story.

Those rats are FOREIGN INVADERS who were left there by ships coming from Europe. They are not native species.

Actually they are indigenous. Many other rodent species arrived with Europeans, but these rodents predate even the aboriginal human inhabitants of Oz by millions of years.

The greatest extinction event observed to date that may be unambiguously assigned to global warming (aka climate change) is extinction of the professional integrity of far too many scientists and journalists.

According to http://www.environment.gov.au/cgi-bin/sprat/public/publicspecies.pl?taxon_id=64477
– “this species is also a case study in how the role of natural and largely unpreventable processes, and the high cost of undertaking any recovery actions in such an isolated location, are important considerations when weighing up how and where conservation actions are directed”, note “natural” and “unpreventable”
– it’s not certain that this was a distinct species from the Cape York melomys
– a recovery plan for these animals was published in 2008, so what happened to that plan? Oh wait, “an integrated program of monitoring, on ground management, searches for other populations and raising public awareness.” The plan DIDN’T include captive breeding. 100 individuals left, and no captive breeding plan, an island frequently inundated, “two weed species already present”, … someone WANTED these animals gone.

An island, the smaller the better, is an ideal way first to develop a new species through isolation from the gene pool of related species and then to wipe it out given normal weather variation or introduction of a predator. When people “look for the bodies”, they don’t find many if they can’t count those from islands.

I’m all in favor of and gladly paid my share of the taxes that went into the ongoing recovery of the Whooping Crane, and the California Condor.
But this rat lookalike on a sandspit, is lunacy. Only thing sillier I’ve ever heard of was a rare fly species that inhabited a region in Southern California, that was scheduled to become divided by a freeway they were building in the area. That would have made two species instead of one, so surely that was a good thing.
But they didn’t want two species of rare flies, so they had to make a ten mile detour around the football field sized piece of land that was home to these flies.
Oh these were very special flies; all eight of them ! Surely each one had a pet name.
Now you give me a class of fifth graders and a gallon of ice cream and some fly swatters, and I will take care of those eight flies for good.
But ten extra miles of freeway, at many megadollars per mile, was their choice over a gallon of ice cream.

There are several papers suggesting that between 2000 and 5000 years ago, the Pacific Ocean experienced a sea level high stand that was at least 1 meter higher than today. The one small atoll on which these rodents live would have been exterminated if sea level was the issue. Yet these alarmists are erroneously suggesting a 3 inch rise since 1900 extirpated this rodent.

The rodent probably floated out to the cay after the high stand of the Holocene Climatic Optimum. Five thousand years is plenty of time for a rodent population to evolve the minor differences it displays from the Cape York melomys on the mainland.

The Bramble Cay melomys was probably best classified as a subspecies of the Cape York melomys. It showed some protein differences and sported a coarser tail due to elevated scales.
The “Old Endemic” rodents of Australia had evolved there since the Miocene or possibly Pliocene in some cases. The “New Endemics” arrived during the Pleistocene. The recently introduced rats, mice and squirrels are invasive and have caused problems. The Cape York and Bramble Cay melomyses are old endemic species.
It’s unclear if sea level rise caused the apparent demise of the Bramble Cay variety. It’s perfectly clear that humans had little if anything to do with the purported sea level rise.
Pure propaganda.

I agree with you, Mr.Worrall.

The Amazing Randi is also speaking at the conference. As I said in a post in another thread, the professional skeptics are all devout congregants of the Church of AGW.

I am not a biologist, but I know a little about the problems of classifying variants and sub-species within a group.
If it is a sub species or variant of other Cape York Melomys (Melomys rubicola — Bramble Cay Melomys), then technically it may not be a ‘separate’ species at all, depending of course on classification.
Biologists can sometimes get too enthusiastic when classifying a ‘species’, which are really much the same as other variants. They sometimes do this of course to claim more species, for various reasons. The Australian dingo for example, is sometimes claimed to be a separate ‘species’ of dog, despite it being just like a wild ordinary dog, morphologically it’s the same as any other dogs, it interbreeds with other dogs, and is really a sub-species at best, if at all.

If Google Earth has it right (big if) then Bramble Cay is 230km from Cape York and 57km from the PNG mainland. Don’t think the rats got there by swimming. Maybe on flood debris? The Cay is right in front of the estuary of the Fly River. So their habitat could conceivably have been affected by the (ongoing) Ok Tedi disaster.

‘… the melomys were last seen in 2009, and after an extensive search for the animal in 2014, a report has recommended its status be changed from “endangered” to “extinct” …’ (The Guardian).
====================================
If they were on an “endangered” list, so precious and their habitat so precarious why weren’t a number trapped and transported to Papua New Guinea where they are alleged to have come from originally and probably still exist?
Maybe the little critters on the island had to be sacrificed to serve a ‘higher cause’.

10 minutes reading of the report reveals some interesting unreported details. The devil is always in the details.
Apparently wild dogs eat them, and are brought to the island periodically. From the report.
“Direct mortality of Bramble Cay melomys individuals due to predation by domestic dogs brought
ashore from fishing vessels (A. Moller-Nielsen pers. comm.) and hunting by visiting indigenous
people from Papua New Guinea (A. Ketchell pers. comm.) would have contributed to pressures on
this isolated rodent population”.
You think?
It may not be extinct. It might occur on other places, including the PNG mainland.
“the possibility that the species occurs elsewhere on islands in the Torres Strait deserves serious
consideration”.
“Together, these observations and associated evidence suggest a New Guinean origin of the Bramble
Cay melomys is not only plausible but perhaps the more likely of the two hypotheses.”
Did they look properly on PNG.? Apparently not.
“However, a possibility exists that the Bramble Cay melomys occurs in the Fly River delta area of
southern New Guinea and so, until this area is adequately surveyed, it may be premature to formally
declare the species extinct.”
This kind of sloppy journalism wouldn’t past muster in any other field except within environmentalism, for reasons that are obscure to me.

Bryant, et al (2011): “Melomys rubicola, found only on Bramble Cay, 50 km south of New Guinea, is more closely related to Australian Melomys, particularly M. capensis, than to any of the New Guinean species. Results suggest that M. rubicola and M. capensis last shared a common ancestor in the early Pleistocene, a time when land bridges existed connecting Bramble Cay to Cape York.”

This is at odds with the later Queensland study, but at least it is based on genetics. Question is, if rubicula has been isolated for a million years, how did they survive Eemian sea levels? There must have been some intermediate safe haven involved where they have now been long extinct.

June 15, 2016 11:00 am

Reading this story I became very curious,.. one of my quirks I guess.
Where exactly is Bramble Cay? A quick inquiry using DuckDuckGo to discover under “Bramble Cay Topo” resulted in an Australian Government site (see the link below). Sure enough there was an entry for the island.
Part of the reason that I started this search was prompted by seeing the transmitting tower stationed on the island. Its presence was to me blatant! I wonder what power level it runs at?
Many people on this thread have mentioned the actual issues that this species faced living on this land from its extremely limited area, and meager elevation, to its’ sparse vegetation. Add to that you have the narrow breeding environment that the creature lives (lived?) in and it would seem to me that the smallest of added stresses could have compounding effects.
According to the map I found, Bramble Cay is surrounded by shallow water and is about 217m long. Heck the larger transmission towers near me are usually located away from populated areas by many hundreds of meters. Did any one pay attention to the power regulations when it came to such a location? Something tells me that nobody skipped a beat in granting the permit to build the tower, IF a permit was even required, which I doubt it was. Such is the nature of bureaucratic thinking and behavior, in my experience.
Now I am not implying that I am paranoid about such technology and the effects of transmission radiation. However I am wondering if there are people on this thread who can also noodle over this situation? This small mammal had no place to go to avoid exposure to this towers transmissions. It’s reported that it nests under debris or in burrows. Those burrows cannot be too deep because the island is barely a few feet in elevation. The occasional below average tropical storm would seem to be sufficient enough to swamp the island. To me it’s astounding that this creature survived at all. It probably washed up on the shores of the island from some other not too distant land mass (see Google Maps view for its’ location).

I don’t want to get into the argument regarding radio frequency radiation.
However the construction of this tower would have required multiple humans tramping all over that island for several days straight. Crushing who knows how many nesting locations.
Then there is the regular maintenance of it.
What is the power source for this transmission tower and how does that impact the islands ecology.
If anyone is looking for a culprit, I suspect Charlie here has found the real one.

From the IUCN Red List, a main reference of endangered species. Emphasis mine:

Habitat and Ecology
Habitat and Ecology: Melomys rubicola is nocturnal (P. Latch pers. comm.). It lives amongst the vegetation on the cay and uses burrows as refuges (P. Latch pers. comm.). The cay, as measured in 2004, is approximately 5 ha in size with a vegetated portion 2.2 ha (Queensland Parks and Wildlife Service, unpublished data). It has one of the most restricted distributions of any mammal species. Little is known of the species’ biology and ecology (P. Latch pers. comm.).
Threats
Major Threat(s): The main threat is to its habitat. The island is eroding through natural processes (Queensland Parks and Wildlife Service, unpublished data), and it is possible that a major storm could eliminate all suitable habitat (Lee 1995). The introduction of any exotic plant, predator, or disease is also a significant threat to this very small, isolated population. Inbreeding depression, while potentially a threat to a small population such as this, is considered a lower risk than natural disasters or invasive species (Dickman et al. 2000).

I did like the term “inbreeding depression”, gave a great image of a bunch of bummed-out teenage mosaic-tailed rats looking at all their sister and brothers and cousins …
