ENVIRONMENTAL CORRELATES OF PLANT SPECIES DISTRIBUTION ON THE NYL RIVER FLOODPLAIN
Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences • Authors: M. A.S. Coetzee --- Botany Department, South Africa K.H. Rogers --- Botany Department, South AfricaThe envisaged construction of a dam on a major tributary of the Nyl River will alter the hydrological regime with consequent effects on the structure and functioning of the downstream floodplain ecosystem (Nylsvley). Attempts to minimise this impact will be... -
Road Building and the Survival of Indigenous Forest in the Southern Cape
Item type: Journal Article • Journal: South African Forestry Journal • Authors: C.J. Geldenhuys --- Saasveld Forestry Research Centre, D. Kotze --- Van Wyk and Louw Consulting Engineers, C.J. van der Merwe --- Saasveld Forestry Research Centre,The effects of road building activities on indigenous evergreen forest were investigated to quantify the impact, to provide guide-lines for minimising damage to forests during future road projects and to gain understanding of the response of different species. The investigation... -
Influence of flood variation on seasonal floodplain vegetation communities in the Okavango Delta, Botswana
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: G Tsheboeng --- Okavango Research Institute, Botswana MC Bonyongo --- Okavango Research Institute, Botswana M Murray-Hudson --- Okavango Research Institute, BotswanaThis study investigated the influence of flooding variation on floodplain vegetation in the Nxaraga Lagoon seasonal floodplains by sampling community composition and soil nutrient content in 1997, when flood levels were unusually low, and again in 2010 when flood levels... -
Evaluation of flooding tolerance in cuttings of Populus clones used for forestation at the Paraná River Delta, Argentina
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: VMC Luquez --- , Argentina FG Achinelli --- , Argentina S Cortizo --- , ArgentinaWe analysed the responses to flooding of 14 poplar clones used for forestation at the Paraná River Delta, Argentina. Some are commercial clones planted in the area, and others belong to a poplar breeding program from the National Institute of... -
Colonial versus solitary breeding: nesting patterns of Brown-throated Martins Riparia paludicola in Morocco
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Peter W Greig-Smith --- , United KingdomThis study explored reasons for variable nesting habits in a hole-nesting bird species that sometimes breeds colonially and sometimes alone. Nesting was surveyed over ten years in natural sand cliffs and similar features created by human activity along a river...
