Although tusklessness was once rare in African savannah elephants, it's become more common like a rare eye color becoming widespread. to construct an explanation of and develop an argument for tusklessness in elephant populations. In this activity, students complete three tasks: 1) interpret and collect information presented through readings and watching a video; 2) use the information collected to construct an explanation for the high incidence of tusklessness in the Gorongosa elephant population; and 3) develop an argument for or against a trend toward increased incidence of tusklessness in the future. h. Why were elephants with tusks targeted during the civil war in Mozambique? Like eye color in humans, genes are responsible for whether elephants inherit tusks from their parents. Cross). ), Answer the questions that follow the cookies in the Luangwa and Zambezi Ecosystems of Zambia Does Mumford! environment. What are the main threats to African elephant populations? Why were elephants with tusks targeted. Because elephants are a keystone species, changes in what they eat can affect the entire landscape, so a high rate of tusklessness in an elephant population could very well have ecosystem-wide consequences..

A term that typically describes a species that no longer has any known living individuals. Poole had previously seen other cases of elephant populations with a disproportionately large number of tuskless females after intense poaching, including in Uganda, Tanzania and Kenya. Campbell-Staton, who conceived of the project while at UCLA, had a hunch that the tuskless phenotype was passed down in the X chromosome, but collecting survey data and blood samples would be key to unraveling this mystery. Their preliminary analysis of fecal samples suggests the Gorongosa elephants are shifting their diet, without long incisors to peel bark from trees.

Ecosystems with a lot of habitat variety and niches can accommodate more species diversity, and this, in turn, increases the resilience of the community. Population patterns uncovered that tuskless mothers tended to have offspring that were 65.7% female, which again strongly suggested an X-linked trait with recessive lethality. Studies of the effects of poaching are not limited to Mozambique. Why are there so many tuskless females in the Gorongosa elephant population? About 35 percent of females older than 25 are tuskless, she says.

A male elephants tusks are bigger and heavier than those of a female of the same age, says Poole, who serves as scientific director of a nonprofit called ElephantVoices. Now researchers have pinpointed how years of civil war and poaching in Mozambique have led to a greater proportion of elephants that will never develop tusks. What was the selective pressure that increased the proportion of tuskless females? Develop an argument to answer the following question: Will the trend toward an increased incidence of tusklessness in a population with heavy poaching lead "The key explanation is that in Gorongosa National Park, the tuskless elephants were the ones which eluded poaching during the civil war and passed this trait on to many of their daughters," Dominique D'Emille Correia Gonalves, a PhD student from the Englands University of Kent on a team researching the phenomenon, said in interviews with British media this week.
