  • Damping-off and stem rot of cowpea in Benin caused by Sclerotium Rolfsii 
    Adandonon, Appolinaire (University of Pretoria, 2006-01-14)
    The damping-off and stem rot disease syndrome is harmful to many cultivated crops. Damping-off and stem rot caused by Sclerotium rolfsii Sacc. on cowpea results in yield losses with serious socio-economic implications. The ...
  • Dancing to the message : African clawless otter scent marking behaviour 
    Jordaan, Rowan Keith; Somers, Michael J.; McIntyre, Trevor (Associazione Teriologica Italiana, 2017-09-04)
