Malaysia, Nov 25 (Canadian-Media): When Imran, last of the species of Sumatran rhinoceros, succumbed to cancer, Sumatran rhinoceros has become extinct in Malaysia, Federal constitutional monarchy of South Asia, media reports said.

Efforts to breed them have been futile but Sabah authorities have harvested their cells for possible reproduction.
"Despite us knowing that this would happen sooner rather than later, we are so very saddened by this news," said Sabah Deputy Chief Minister Christina Liew, who is also environment minister.
Liew said that over the past few years, Iman' deteriorating health condition due to sudden massive blood loss, but wildlife officials managed to nurse her back to health several times and were successful in obtaining her egg cells for a possible collaboration with Indonesia for reproduction of the critically endangered species through artificial insemination.
The Sumatran rhino, the smallest of five rhinoceros species, once roamed across Asia as far as India, but due to deforestation and poaching, its numbers have shrunk drastically.
According to the estimates of The World Wide Fund (WWF) conservation group there are only about 80 left, mostly living in the wild in Sumatra and Borneo in Indonesia.
The Sumatran as well as the Black and Javan rhinoceros have been identified, by the International Union for the Conservation of Nature (IUCN), as being critically endangered. Both African and Sumatran rhinoceros have two horns, while the others have a single horn.

Ottawa, Nov 19 (Canadian-Media): A proposal for an innovative approach to biodiversity conservation has been made by a research paper affiliated with the University of Toronto, in the form of ‘Dynamic Protected Areas,’, in other words, transient protected areas that change according to the biological concerns of the meta-population, media reports said.

After discussing the pros and cons of both the existing strategy and the proposed new strategy in an interview with The Varsity, Dr. Marie-Josée Fortin, a co-author of the paper and a professor at the Department of Ecology & Evolutionary Biology concluded that the existing strategies' pre-established notions about biodiversity, conservation, and legislation needed to be updated to include the new multi-faceted conservation strategy to address the climate crisis.
Currently, the ‘Permanent Protected Area’ status of preserving biodiversity in Canada is limited to fixed spaces set aside to minimize human intervention and can take a long time to come into effect because of the slow legislative process.
Moreover, the increasing number of natural environments converted for human use make it more difficult to find land for permanent protected areas.
The static nature of permanent protected areas also poses a significant ecological dilemma due to the categorization of biological organisms at many different levels to specifically addresses meta-populations, meta-communities, and meta-ecosystems.
For example, a ‘meta-population’ refers to many populations at once and considers how they interact with one another, between different locations instead of one fixed location.
Permanent protected areas alone may be inadequate in preserving biodiversity as the species within these areas are not completely isolated from their surrounding environments. In other words, the region is only protected for as long as the environment demands.
The alternative idea of ‘Dynamic Protected Areas’ advantageously focuses on terrestrial species that undergo annual migration facilitating the government to establish dynamic protected areas that travel with that species and that only last as long as the migration does.
Although dynamic protected areas still face the challenges of economic and legislative considerations, Fortin and her colleagues support the strategy’s implementation, because it acknowledges that the environment has been and would always be undergoing change.

Ottawa, Nov 8 (Canadian-Media): Canadians have been recommended by the Nature Conservancy of Canada (NCC) to leave a layer or two of leaves on the ground as nature conservation instead of cleaning them up to support backyard biodiversity, media reports said.

Dan Kraus, NCC’s senior conservation biologist, says leaves can provide important habitat for many species such as such as toads, frogs and many pollinators to hibernate under leaves as leaves provide an insulating blanket to protect from very cold temperatures and temperature fluctuations during the winter.
Another benefit is that the leaves break down into a natural mulch that helps fertilize the soil. But a thick pile of leaves can be bad for grass and other plants by smothering them. A light covering, spread around, can improve garden health, NCC said.
Stephen Hazell, director of policy at conservation charity Nature Canada, agrees.
Leaves can be stashed under shrubs or trees to help prevent the freeze-thaw cycle, the NCC recommended.
“The most energy-efficient solution is to allow nature to do its thing and for the leaves to naturally break down in your yard,” Kraus said.
“Plant stalks and dead branches also provide habitat for many species of insects...Providing winter habitats for our native birds and insects is just as important as providing food and shelter during the spring and summer.”
New Brunswick, Nov 3 (Canadian-Media): A finding of a necropsy performed by the Atlantic Marine Conservation Society confirmed that the death of a 40-year-old male North Atlantic right whale found floating in U.S. waters was due to its entanglement in Canadian fishing gear, media reports said.

"When they did the necropsy they looked at where the wraps were, where marks were, and they seemed to line up pretty well with what they had seen in August," said National Oceanic and Atmospheric Administration spokesperson Jennifer Goebel.
In total eight whales have been found dead in Canadian waters in 2019.
Scientists estimate there are only about 400 North Atlantic right whales left in existence with fewer than 100 breeding females.
