Study suggests the Tasmanian tiger survived into the 21st century
by James Fair on 4 February 2021
The Tasmanian tiger, or thylacine, most likely went extinct in the late 1990s or early 2000s, and could still persist in the most remote parts of the island, according to new research that is still undergoing peer review.
More than 1,200 records of sightings and physical evidence from 1910 up to 2019 were collected and collated by scientists at the University of Tasmania and used to model where and when the thylacine is likely to have persisted.
This study challenges the accepted consensus that the thylacine went extinct in the decade or two after the last known individual died in Hobart Zoo in 1936.
Researchers from Australia studied epaulette sharks from the Great Barrier Reef
This species lays eggs that are left unprotected for four months before hatching
The team explored the impact of increasing water temperatures up to 87.8°F
Warmer conditions cause the embryos to grow faster and use up their yolk sac
This meant the hatchlings emerged earlier and weaker than they would normally
Temperatures on the Great Barrier Reef are expected to hit 87.8°F this century

Podcast: Tiger on the highway 17 December, 2020 - 01:40
The Trans-Sumatran Highway is a $1.1 billion dollar project spanning 2,700 kilometers – from Banda Aceh in the north to Bandar Lampung in the south – and is designed to connect the island’s agribusiness and mining sectors in an effort to boost commodity exports. Forty percent of the land needed for the highway has yet to be acquired, and it is slated to run right through – rather than around – biodiverse forests, the Leuser Ecosystem, Kerinci Seblat National Park, and the Batang Toru Ecosystem. Recently a critically endangered Sumatran tiger was spotted on a construction site in Riau province, sparking wildlife experts to call for the protection of the species. Some have described these road projects as ‘opening up Pandora’s box.’ To discuss the impact of – and alternatives to – such infrastructure projects, Mongabay Explores podcast host Mike DiGirolamo reached Hariyo “Beebach” Wibisono in Jakarta: h
Podcast: Tiger on the highway
by Mongabay.com on 16 December 2020
The wildlife rich island of Sumatra is experiencing a road building boom, causing some of its iconic creatures to be seen by construction workers: a photo of a Sumatran tiger crossing a highway work-site went viral this summer, for example.
Less than 400 of these critically endangered animals exist, and they need space despite their diminutive stature: up to 250 square kilometers for each one’s territory.
To discuss the conservation impact of – and alternatives to – such infrastructure projects, Mongabay’s podcast interviewed Hariyo “Beebach” Wibisono, a research fellow at the San Diego Zoo Global & director of SINTAS Indonesia, plus Bill Laurance, a distinguished professor at James Cook University.
