Supposed sightings have kept the dream of finding thylacines alive but mathematical models pour cold water on the claims

In 2000 researchers with Project Lazarus began recovering and sequencing DNA of the extinct thylacine, or Tasmanian tiger, from museum specimens.

«We also found evidence of a population crash, reducing numbers and genetic diversity of thylacines in Tasmania around the same time,» says Associate Professor Austin.

The researchers from the University's Australian Centre for Ancient DNA (ACAD) found that a large and genetically diverse population of thylacines lived in western regions of Australia right up to their extinction from the mainland around 3000 years ago, separated from the eastern population.

«Our multi-species models showed that dingoes could reduce thylacine and devil populations through both competition and direct predation, but there was low probability that they could have been the sole extinction driver,» Dr Prowse says.

This provided the first genetic evidence that mainland thylacines split into eastern and western populations in southern Australia before the last Ice Age peak of about 25,000 years ago.

«Thylacines once lived across most of the Australian mainland, but by the time Europeans arrived in the late 1700s they were found only in Tasmania.

«We wanted to understand why thylacines went extinct on the mainland, but survived in Tasmania,» says lead author and PhD student Lauren White.

«We agree that it's exceedingly unlikely [that thylacines still exist]-- we've been saying that from the outset,» he says.

Two tantalising sightings of possible Tasmanian tigers have inspired a renowned conservationist to find out if thylacines really are extinct

I have been chastising friends who believe thylacines may still be running around the Australian bush, quoting the 1 in...

This fits with the ecological niches of these two animals: Tasmanian devils are scavengers while thylacines were hunters, and the latter foraging strategy entails more planning.

This suggests that thylacines devoted more of their cortex to complex cognition, particularly action planning and possibly even decision making.

Shall I post a video clip on YouTube so people can watch the frog move about, like the famous film clip of the last thylacine?

Limited Run Games has announced that it will release a physical version of Thylacine Studios» Siralim for PS Vita and PS4 on April 27, 2018.

However, some behaviors can be inferred from brain structure, so Berns and Ashwell scanned two thylacine brains and reconstructed neural connections.

The University of Adelaide study, published in the Journal of Biogeography, traces the history of thylacine populations over the last 30,000 years.

«Perhaps because the public perception of dingoes as «sheep - killers» is so firmly entrenched, it has been commonly assumed that dingoes killed off the thylacines and devils on mainland Australia,» says researcher Dr Thomas Prowse, Research Associate in the School of Earth and Environmental Sciences and the Environment Institute.

Dingoes have been unjustly blamed for the extinctions on the Australian mainland of the Tasmanian tiger (or thylacine) and the Tasmanian devil, a new study has found.

«There was anecdotal evidence too: both thylacines and devils lasted for over 40,000 years following the arrival of humans in Australia; their mainland extinction about 3000 years ago was just after dingoes were introduced to Australia; and the fact that thylacines and devils persisted on Tasmania, which was never colonised by dingoes.

«Our results support the notion that thylacines and devils persisted on Tasmania not because the dingo was absent, but because human density remained low there and Tasmania was less affected by abrupt climate changes.»

The researchers built a complex series of mathematical models to recreate the dynamic interaction between the main potential drivers of extinction (dingoes, climate and humans), the long - term response of herbivore prey, and the viability of the thylacine and devil populations.

In a paper published in the journal Ecology, the researchers say that despite popular belief that the Australian dingo was to blame for the demise of thylacines and devils on the mainland about 3000 years ago, in fact Aboriginal populations and a shift in climate were more likely responsible.

Dingoes have been unjustly blamed for the extinctions on the Australian mainland of the Tasmanian tiger (or thylacine) and the Tasmanian devil, a University of Adelaide study has found.

Since it was settled in 1803, the island has lost only one mammal, the Tasmanian tiger (or thylacine)-- a wolfish, striped, carnivorous marsupial.

In northern Australia a research team not connected to the GWC initiative is currently undertaking fieldwork with the equally sensational goal of rediscovering the thylacine, or «Tasmanian tiger,» which has been presumed extinct for the past 80 years.

The thylacine, or Tasmanian tiger, so called for its striped fur, once sat atop a food chain isolated for millennia by miles of ocean.

Colonial sheep farmers, blaming the thylacine for stock losses, crowded it out of its range.

In 1999 the Australian Museum announced a complex plan to clone the thylacine with DNA extracted from a 140 - year - old pup preserved in alcohol.

A research group led by Penn State's Webb Miller has found similarities between the thylacine's genome and that of the numbat, a marsupial anteater native to western Australia (right).

The thylacine, a hyena - size marsupial predator with long jaws and a spectacular gape, roamed freely on the island of Tasmania until the Europeans arrived around 1800.

In Tasmania, remorse over the thylacine's annihilation played a role in the decision to preserve over a quarter of the island as one of the world's largest intact temperate wildernesses.

Unlike the devil, however, it appears that the population of thylacines was expanding at the time of European arrival.»

The researchers generated 51 new thylacine mitrochondrial DNA genome sequences from fossil bones and museum specimens — the largest dataset of thylacine DNA to date.

Ancient DNA extracted from fossil bones and museum specimens has shed new light on the mysterious loss of the Tasmanian tiger (thylacine) from Australia's mainland.

Several species — such as the thylacine, a carnivorous marsupial, or the forest ox known as the kouprey — have been searched for many times without success, that likely indicates they really are extinct, Fisher and Blomberg suggest.

«The thylacine was a marsupial carnivore, now infamous for its recent human - driven extinction from Tasmania following the arrival of Europeans and their bounty hunting schemes,» says project leader Associate Professor Jeremy Austin, Deputy Director of ACAD.

Under the most optimistic scenario, they calculate that thylacines could have clung on only until the late 1950s (bioRxiv, DOI: 10.1101 / 123331).

Tasmanian tigers, or thylacines (Thylacinus cynocephalus), were marsupial carnivores native to Australia.

Now Colin Carlson at the University of California, Berkeley, and his colleagues have used data on confirmed and unconfirmed sightings from 1900 onwards to model the extinction of thylacines.

The Tasmanian tiger, or thylacine, was a carnivorous marsupial and the apex predator in Tasmania.

According to a new study, the thylacine was struggling even before humans hunted them to extinction.

After sequencing the complete genome from a century - old specimen, the researchers investigated the evolution of the thylacine to potentially help current endangered species avoid the same fate.

The rapidly falling costs of genome sequencing has sparked initiatives to sequence the genomes of all living species, and thanks to improved ancient DNA methods the genomes of extinct species such as the woolly mammoth, thylacine, and passenger pigeon are also attainable.

In fact, some species, such as the thylacine, were eradicated because they were considered a threat to human life — specifically, that they were killing off herds of sheep.

Scientists have produced the first high - quality genomic sequence for the Tasmanian tiger (Thylacinus cynocephalus), also known as the thylacine.
