The Spearman's rank correlation test showed no shifts in the diet of A. barnardi from Noordhoeks River and A. gilli from Rondegat River with a change in size and season (p>O.OS). However, there was a shift in the diet of A. gilli from the Noordhoeks River which could suggest a distinct patchiness of benthic macroinvertebrates between the riffle feeding areas used by juveniles and other biotopes used by adults. The occurrence, in stomach contents, of other prey items from a wide variety of taxa and the presence of allochthonous material from the terrestrial environment could suggest an opportunistic feeding guild for both Austroglanis species. The life-history traits of A. gilli and A. barnardi, which are charaterized by slow growth, long life span and low relative fecundity, indicate that both species are relatively precocial and K-selected. The population of a precocial species is relatively stable and if population numbers were to be greatly reduced, they would require a long time to rebuild. An urgent conservation intervention is therefore recommended for Austroglanis spp. so as to maintain the diversity of populations within these species. The creation of protected river reserves and raising public conservation awareness may minimise activities that result in altered river hydrology and the destruction of complex benthic habitats.]]> Thu 13 May 2021 07:20:05 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:4507 Thu 13 May 2021 07:07:10 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:4663 Thu 13 May 2021 04:41:41 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5086 Thu 13 May 2021 03:41:37 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:2992 Thu 13 May 2021 03:16:39 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:5400 Thu 13 May 2021 01:54:30 SAST ]]> https://vital.seals.ac.za/vital/access/manager/Repository/vital:4686 Thu 13 May 2021 01:02:12 SAST ]]>
