The black rhinoceros is a mammal found in Africa. Weighing in at up to 1,350 kg, these rhinos can live roughly 35 years. Gestation in the black rhino lasts for 15-16 months, with calves staying under the mother’s parental care for up to four years.
Black rhinos have been hunted extensively by humans for their horns. Poaching pressure has reduced the black rhino population to an endangered level. Ongoing efforts are attempting to save the animal from extinction.
How can the black rhino survivorship strategy be categorized?
K-selection, type I
K-selection, type III
r-selection, type I
r-selection, type III
In 1976, the dominant finch on Daphne Major in the Galapagos Islands was the medium ground finch, with a population of 1,200. In 1977, a drought struck the island negatively affecting most of the vegetation. As a result, the population of medium ground finch dropped to 180 due to starvation. In 1983, however, a large amount of rainfall fell on the island creating optimal conditions for vegetation. The medium ground finch population increased to 1,100. What type of factor affected medium ground finch populations in 1977 and 1983?
Density independent
Logistic
Density dependent
Biotic
