The survival curves of four species of African ungulate-impala, buffalo, zebra,

Question

The survival curves of four species of African ungulate-impala, buffalo, zebra, and warthog-derived from skulls found in the Akagera National Park, Rwanda, are com- pared. Three of the species are shown to have the typical logarithmic negatively-skewed adult curve shown by undisturbed large mammal populations, but warthogs apparently have a heavy age-constant number of deaths to middle-age. Attention is drawn to the limitations of time- specific data in the study of population dynamics.

Can you please explain to me what this means in simple English?

Explanation / Answer

There are four aftrican ungulate species were selected from Akagera National Park of Rwanda for the analysis. They are buffalo, impala, zebra and warthog. Survival curve denotes that the relationship between the survival of a species and age of the particular population. Three species impala, buffalo and zebra shown a negative survival curve as the survival of these species were lower when compared with age of the population whereas in case with warthog the same level of survival and death rates noted among the populations.
