  • Modelling the role of correctional services on gangs : insights through a mathematical model 

    Nyabadza, F.; Ogbogbo, C. P.; Mushanyu, J. (Royal Society, 2017)
    Research has shown that gang membership increases the chances of offending, antisocial behaviour and drug use. Gang membership should be acknowledged as part of crime prevention and policy designs, and when developing ...
  • Host-seeking efficiency can explain population dynamics of the tsetse fly Glossina morsitans morsitans in response to host density decline

    Although research on human-mediated exchanges of species has substantially intensified during the last centuries, we know surprisingly little about temporal dynamics of alien species accumulations across regions and taxa. ...
  • Raising the flag on marine alien fouling species 

    Peters, Koebraa; Sink, Kerry; Robinson, Tamara B. (Regional Euro-Asian Biological Invasions Centre, 2017)
    Harbours are known introduction foci of marine alien species. They act as recipients of new introductions and as sources for regional spread. We report on subtidal surveys of fouling communities from 14 harbours along the ...
