Of these six only three species formed > 10 percent. They are the shrubs Acacia karroo, Pappea capensis and Grewia robusta. These were followed by the shrub Portulacaria afra, the dwarf shrub Zygophyllum lichtensteinianum and the grass Cynodon dactylon all contributing between 5 - 10 percent. There were definite seasonal dietary shifts with preference to different plant species. The shift takes place between the wet seasons (winter and spring) and the dry season (summer). Herbaceous species such as Cynodon dactylon and Erharta calycina were favoured in the winter/wet season. Shrubs such as P. capensis, P. afra and dwarf shrubs such as Limeum aethiopicum and Z. lichtensteinianum were favoured during the spring/wet and summer/dry seasons. Nyala habitat use in BPGR differed significantly from expected use when taking the relative area of habitats into consideration. However nyala did not display signififcantly different habitat preferences between seasons. Male and female nyala displayed differences in foraging behaviour at the plant form, plant species and habitat scale. Males preferred a greater proportion of shrubs and females a greater proportion of dwarf shrubs. Males preferred the shrubs Pappea capensis and Portulacaria afra the most and females preferred the dwarf shrubs Limeum aethiopicum and Zygophyllum lichtensteinianum the most. Plant species site availability varied significantly between the sexes, indicating that males and females selected different feeding paths. The difference in their feeding strategy appears to be related to the selection of plants that best satisfy the nutrient requirements of each sex. These findings are in agreement with the results from earlier studies on nyala sexual dimorphism. At the habitat scale females selected more for open dwarf shrubland and males more for densely vegetated habitats. This appears to be as a result of males attempting to maximize their foraging opportunities by selecting areas that offer food in greater quantities. Nyala in BPGR appear to co-exist with kudu and eland through spatial resource partitioning. This is suggested to be due to the influence of body size-gut size relationships on forage selectivity.]]> Wed 12 May 2021 22:41:35 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:9830 Wed 12 May 2021 22:39:43 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:22103 Wed 12 May 2021 22:30:56 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:9832 Wed 12 May 2021 20:49:36 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:8944 Wed 12 May 2021 20:25:20 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:8533 Wed 12 May 2021 20:09:21 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:9811 Wed 12 May 2021 18:44:03 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:8946 Wed 12 May 2021 18:36:26 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:10742 Wed 12 May 2021 18:36:25 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:9824 Wed 12 May 2021 18:18:06 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:10124 Wed 12 May 2021 16:07:13 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:9604 Wed 12 May 2021 16:06:07 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:10737 Wed 12 May 2021 15:58:05 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:40393 Wed 12 May 2021 14:54:26 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:8916 Thu 13 May 2021 11:45:23 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:9697 Thu 13 May 2021 08:17:41 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:10736 Thu 13 May 2021 07:32:00 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:9375 Thu 13 May 2021 07:13:31 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:10416 Thu 13 May 2021 06:18:26 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:10126 Thu 13 May 2021 06:18:25 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:10755 Thu 13 May 2021 05:23:01 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:10594 Thu 13 May 2021 04:42:10 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:10738 Thu 13 May 2021 04:20:04 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:9751 Thu 13 May 2021 02:43:51 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:8945 Thu 13 May 2021 02:40:10 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:9818 Thu 13 May 2021 02:15:24 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:9640 Thu 13 May 2021 01:58:51 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:9391 Thu 13 May 2021 01:36:14 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:21136 Thu 13 May 2021 01:23:57 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:9633 Thu 13 May 2021 00:51:09 SAST ]]> https://commons.ru.ac.za/vital/access/manager/Repository/vital:9639 Thu 13 May 2021 00:50:50 SAST ]]>
