The public is increasingly questioning equestrianism's social license to operate. While the focus historically centered on horseracing, increased scrutiny is now being placed on how dressage, showjumping, and eventing are addressing equine management and welfare concerns. Nominated equestrian federation and equestrian organization experts ( = 104) directly involved in international and/or national-level horse sports took part in a four-stage, iterative Delphi to obtain consensus on what factors should be considered essential to manage sporthorse health and welfare.

Despite numerous studies investigating responses to visual perception, there is limited research into how horses respond to different auditory stimuli. Although 'noise-damping' ear covers are frequently used on sport horses to minimise distraction from external auditory stimuli, the effectiveness of ear covers has not been established. This study aimed to (i) investigate the responses of horses to different sounds commonly present in a competition environment, and (ii) compare these responses in the presence and absence of ear covers.

Article Synopsis
  • Elevated metal concentrations in marine organisms can be harmful to both marine life and humans who eat them, with a recent study focusing on brown mussels in Algoa Bay, South Africa.
  • Researchers collected mussels from seven sites and found significant differences in metal concentrations, some of which were linked to local pollution sources.
  • Overall, mussels from Algoa Bay are generally considered safe for human consumption, aside from one site with elevated lead levels, but potential health concerns remain when combined with other contaminants like bisphenols and UV filters.
