Welcome to Animal | Vegetable | Mineral

I never cease to be awed by the splendor of the natural world, by the forces that shape the earth, and by the diversity and ingenuity of the life that populates it.

Animal | Vegetable | Mineral is a group where those who share this fascination can discuss the Earth and animal sciences of geology, volcanology, seismology, ecology, ethology, primatology, entymology—basically all the –ologies of the natural world.

Why Are Gorillas Committing Mob Violence?

That should be easy to figure out.

Limited resources. The same reason humans commit mob violence.  Though it may be different with humans in that they are violent for meaningless trinkets.

Happy xmas.

Comment by Chris yesterday

Mircats are great as are other beings such as the great apes, who are probabably fighting for survival with the limited resources being taken from them from human incursion.

What is it with some Chinese superstition about verility? As wealth in China grows so will the trade in Elephant Tusks, Tiger Bones, Rhinocerous hornes and etcetera.

African elephants are being born without tusks due to poaching, researchers say

The species could become extinct in some areas, with those elephants that do survive evolving to be almost completely tuskless

An increasing number of African elephants are now born tuskless because poachers have consistently targetted animals with the best ivory over decades, fundamentally altering the gene pool.

In some areas 98 per cent of female elephants now have no tusks, researchers have said, compared to between two and six per cent born tuskless on average in the past. 

Almost a third of Africa’s elephants have been illegally slaughtered by poachers in the past ten years to meet demand for ivory in Asia, where there is still a booming trade in the material, particularly in China.

About 144,000 elephants were killed between 2007 and 2014, leaving the species at risk of extinction in some areas. Meanwhile those African elephant populations that do survive could become virtually tuskless, like their Asian cousins, researchers have warned.

Joyce Poole is head of the charity Elephant Voices and has been tracking developments in the species for more than 30 years. She told she had seen a direct correlation between the intensity of poaching and the percentage of females born without tusks in some of the herds she monitored. 

In Gorongosa National Park in Mozambique, 90 per cent of elephants were slaughtered between 1977 and 1992, during the country's civil war. Dr Poole said that because poachers disproportianetly targetted tusked animals, almost half the females over 35 years of age have no tusks, and although poaching is now under control and the population is recovering well, they are passing the tuskless gene down to their daughters: 30 per cent of female elephants born since the end of the war also do not have tusks.

“Females who are tuskless are more likely to produce tuskless offspring,” she said.

The most striking example is in the Addo Elephant National Park in South Africa, where 98 per cent of female elephants have no ivory. Big game hunters there had killed all but 11 elephants by the time the park was created in 1931. Four of the eight surviving females were tuskless.

In 2008, scientists found that even among elephants that remained tusked, the tusks were smaller than in elephants' a century before – roughly half their previous size.

Although not having tusks may protect elephants from poaching, it not ideal.

“Tusks are used to dig for food and water, to dig up trees and branches and move them around, for self-defence and for sexual display," the BBC reported. 

“Conservationists say an elephant without tusks is a crippled elephant."
