The situation of hunting elephants in Africa is rampant. Some surveys have found that elephants are facing the pressure of killing and killing, and they no longer grow long ivory to avoid hunting. Mozambique currently has about one-third of the mother elephants born without long ivory, and the researchers are learning about the genetics of these elephants and the effects of ivory on these elephants.
In the past years of civil war, Mozambique exchanged funds for ivory in Gorongosa National Park, and about 90% of African elephants in the park were massacred. The civil war ended in 1992, but one-third of the female elephants born after the civil war did not grow ivory.
Joyce Poole, director of the non-profit conservation organization Elephant Voices and elephant behavioralist, said that about 4,000 elephants were inhabited by Gorongosa Park decades ago, but during the civil war, elephants The number has dropped to hundreds of heads. In an unpublished study, she wrote that among the 200 known female elephants, 51% of the mothers who had survived the civil war and are currently 25 or older have no ivory; and among the female elephants born after the civil war, 32% are born without ivory.
Poole explained that the ivory of the male elephant is larger and heavier, but because the illegal hunting is very embarrassing, the hunter has not let go of the older female elephant. “Over time, as the older mother elephants die, you begin to find ivory. The proportion of mother elephants is very high.”
A similar situation has occurred in other countries where elephants are indiscriminately killed. In the Addo Elephant National Park in South Africa, 98% of the 174 female elephants have not developed ivory since the beginning of 2000.
Elephant ivory can be used to dig out water, or to dig bark for food, helping them to travel farther to find habitat. Scientists are currently collecting data to study the effects of ivory-free ivory on them and the surrounding ecosystems.
