[PODCAST] A biotech company in the United States made headlines last month by revealing photos of genetically modified gray wolves, calling them “dire wolves,” a species that hasn’t existed for more than 10,000 years.

Some observers assert to the public that “de-extinction” is real. But it’s not, says podcast guest Dieter Hochuli, a professor at the Integrative Ecology Lab at the University of Sydney.

Mongabay Environmental News · ‘De-extinction’ isn’t just misleading — it’s dangerous, ecologist saysA biotech company in the United States made headlines last month by revealing photos of genetically modified gray wolves, calling them “dire wolves,” a species that hasn’t existed for more than 10,000 years. Colossal Biosciences edited 14 genes among billions of base pairs in gray wolf DNA to arrive at the pups that were shown, […]

PSA: The #Crisafulli #LNP government of #Queensland wants to expand native forest logging as part of it's anti #conservation pro #logging "Primary Industries Prosper 2050" blueprint.

*Not* protect or continue native logging. No. The plan is to *EXPAND* it.

It's been carefully shuffled out of sight, being slid out under cover of all the noise from the federal parties during the election.

There is a consultation period now open. PLEASE PLEASE PLEASE submit your thoughts on this proposal, and encourage others to do so. Our survival depends on our native forests. Without them there is no future for our land, and by extension no future for us - just eroding soils, dead rivers, dessicated land and mass extinction.

Defend life. Defend the land we belong to. Defend the forests that sustain us.

Even the worst #massextinction had its oases
Scientists have debated whether this event caused nearly as much terrestrial destruction. Now, researchers from the Nanjing Institute of Geology and Paleontology (NIGPAS) of the Chinese Academy of Sciences suggest that #terrestrial #ecosystems did not suffer nearly as much as the #oceans.

#SouthernRightWhale #population growth has stalled, scientists say, with a possible 'onset of a decline'.

Australia's southern right whale population growth has #stalled, raising questions about the recovery of a species that was nearly driven to #extinction by historical #whaling, according to a new study.

**Threshold fertility for the avoidance of extinction under critical conditions**

“_The results indicate that the fertility rate should exceed 2.7 to avoid extinction. The extinction threshold is reduced by a female-biased sex ratio. We argue that the present results explain the observed phenomena of female-biased births under severe conditions as an effective way to avoid extinction._”

journals.plos.orgThreshold fertility for the avoidance of extinction under critical conditionsThe developed countries now face a low fertility crisis. The replacement level fertility (RLF) is conventionally considered to be 2.1 children per woman, in which demographic stochasticity arising from random variations in individual offspring numbers is ignored. However, the importance of demographic stochasticity casts doubts on the adequacy of the replacement level fertility of 2.1, especially in a small population. Here, we investigate the extinction threshold for the fertility rate of a sexually reproducing population caused by demographic stochasticity. The results indicate that the fertility rate should exceed 2.7 to avoid extinction. The extinction threshold is reduced by a female-biased sex ratio. We argue that the present results explain the observed phenomena of female-biased births under severe conditions as an effective way to avoid extinction. Furthermore, since fertility rates are below this threshold in developed countries, family lineages of almost all individuals are destined to go extinct eventually.

#Kerala fishermen up in arms against #DeepSeaMining proposal off #Kollam coast

March 22, 2025

"The fishermen in Kerala have already launched several protests against the proposed plan to open up the sea to private mining companies as part of the Union Government’s ‘Blue Economy’ initiative.

"All the fishermen’s associations stand united in their protests against this proposal, alleging that it would bring an end to the fisheries sector in the country, not only in the #ArabianSea but also in the #BayOfBengal.

“ 'The mining, according to the scientific report we have, can disturb the seabed and completely destroy fish spawning habitats. It can also release poisonous gases trapped on the #DeepSeaFloor, causing severe #environmental issues,' Kerala Minister for Fisheries, Saji Cherian, told PTI.

"He said that deep-sea mining requires huge investments and heavy machinery, meaning only #multinational #corporations will be involved, making these areas completely inaccessible to poor fishermen.

"The Kerala government, which is strongly opposing this project, passed a resolution in the Assembly urging the Centre to withdraw it.

"The Minister said the proposed site, off the Kollam shore in Kerala in the Arabian Sea, is very rich in marine resources and serves as a lifeline for fishermen from Kerala and other states.

“ 'We have a highly diverse and extensive fish population in this area. The mining will completely wipe out this habitat, severely affecting the livelihood of fishermen in our region,' Saji Cherian said."
