The region of Souss-Massa in central Morocco exhibits a high incidence of scorpion envenomings,... -
A review of parasitic fauna of Egyptian amphibia
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Osama MS Mostafa --- Ain Shams University, Egypt Kareem Morsy --- King Khalid University, Saudi Arabia Saad Bin Dajem --- King Khalid University, Saudi Arabia Mahmoud HY Fedda --- Ain Shams University, EgyptThe world's biodiversity is facing a significant threat, and amphibians are particularly susceptible, being the most vulnerable vertebrate group globally. The decline in the amphibian population has been attributed, in part, to parasitic infection. Egyptian amphibian fauna was poorly studied,... -
Comparing seismic survey mitigation regulations: lessons for South Africa from international frameworks
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: J Purdon --- Tshwane University of Technology, South Africa MJ Somers --- University of Pretoria, South Africa FW Shabangu --- University of Pretoria, South Africa Y Doh --- , France J Scheun --- Tshwane University of Technology, South AfricaUnderwater seismic surveys generate high-intensity, low-frequency noise that can negatively affect a range of marine fauna. As a result, countries have implemented mitigation regulations to reduce the potential impacts of this activity. This study examines seismic survey mitigation regulations from...
