The Reed Cormorant (Phalacrocorax africanus) was the dominant species throughout the study, with a mean of 8.25 (SD ± 7.90) individuals per count. Mean values of the Pied Kingfisher (Ceryle rudis) and Giant Kingfisher (Megaceryle maximus) were 3.42 (SD ± 1.20) and 1.17 (SD ± 0.60) individuals per count, respectively. The remaining species revealed mean values < 0.5 individuals per count. The highest bird numbers were recorded in winter reflecting the migration of large numbers of the Reed Cormorant into the system. Breaching events were associated with a decrease in total bird numbers, which was most likely due to loss of potential foraging habitat (littoral zone) for waders resulting from reduced water levels. Monthly food consumption by all piscivorous birds revealed large temporal variability, ranging from 26.35 to 140.58 kg per month. The observed variability could be linked to mouth phase and bird numbers.]]> Wed 12 May 2021 19:41:05 SAST ]]> The development of an in vitro system for the production of drug metabolites using microsomal enzymes from bovine liver https://vital.seals.ac.za/vital/access/manager/Repository/vital:4087 Wed 12 May 2021 18:57:24 SAST ]]> The effects of melatonin on the testis, epididymis and sperm physiology of the Wistar rat https://vital.seals.ac.za/vital/access/manager/Repository/vital:5681 Wed 12 May 2021 18:30:37 SAST ]]> Assessment of organochlorine pesticide residues in fish samples from the Okavango Delta, Botswana https://vital.seals.ac.za/vital/access/manager/Repository/vital:4404 Wed 12 May 2021 16:23:00 SAST ]]> The precambrian iron-formations in the Limpopo belt as represented by the magnetite quartzite deposits at Moonlight, Koedoesrand area, Northern Transvaal https://vital.seals.ac.za/vital/access/manager/Repository/vital:5064 Thu 13 May 2021 08:20:51 SAST ]]> Synthesis and electrochemistry of octapentylthio phthalocyanine complexes of manganese, titanium and vanadium https://vital.seals.ac.za/vital/access/manager/Repository/vital:4368 Thu 13 May 2021 07:39:04 SAST ]]> Remora : implementing adaptive parallelism on a heterogeneous cluster of networked workstations https://vital.seals.ac.za/vital/access/manager/Repository/vital:4673 Thu 13 May 2021 07:08:28 SAST ]]> Removal of copper and nickel from solution by the non-viable biomass of the water fern Azolla filiculoides in an upscaled fixed-bed column system https://vital.seals.ac.za/vital/access/manager/Repository/vital:3914 Thu 13 May 2021 05:08:48 SAST ]]> Occupational health and safety and industrial relations in the South African construction industry : case studies of selected construction firms in Grahamstown https://vital.seals.ac.za/vital/access/manager/Repository/vital:3401 Thu 13 May 2021 00:22:03 SAST ]]> A comparative study of the performance of English and Xhosa speaking children on the Wechsler Intelligence Scale for Children-Revised (WISC-R) https://vital.seals.ac.za/vital/access/manager/Repository/vital:3150 Thu 13 May 2021 00:16:04 SAST ]]> Vulnerability, irreplaceability and reserve selection for the elephant-impacted flora of the Addo National Elephant Park, Eastern Cape, South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:4202 Thu 13 May 2021 00:09:09 SAST ]]>
