13) GeneticsThe Nile hippopotamus and the pygmy hippopotamus, both have 36 chromosomes (thus 18 pairs), all metacentrics (Gerneke, 1965; Hsu & Benirschke, 1977). Only the Y-chromosome is acrocentric and it is larger in the pygmy hippopotamus. The two karyotypes are otherwise essentially similar. Hybrids are unknown.Karyotype of male Nile hippopotamus.Karyotype of female Nile hippopotamus.Karyotype of male pygmy hippopotamus.
The two main branches of Ecolgy are: 1.) Autecology - the study of the interactions of an individual organism or a single species with the living and nonliving factors of its environment. Autecology is primarily experimental and deals with easily measured variables such as light, humidity, and available nutrients in an effort to understand the needs, life history, and behaviour of the organism or species. 2.) Synecology - the ecological study of different natural communities or ecosystems.
