    Abstract : The newest Scottish government Biodiversity Strategy prioritises control of overabundant deer populations. Ecological theory and real-life instances suggest an unorthodox deer management solution: wolf reintroduction (WR). Theoretically, wolves would prey on deer, thus alleviate grazing pressure on Scottish vegetation and help landscapes thrive. READ MORE

  4. 3. Disentangling risk in a multi-predator landscape : roe deer respond to differing patterns of risk to lynx, wolves and humans through shifts in their habitat selection

    Keywords : Canis lupus; Capreolus capreolus; indirect effects; landscape of fear; Lynx lynx; multi-predator systems; predation risk; Scandinavia; spatial risk patterns; ungulates;

    Abstract : Predation risk is known to evoke behavioural responses in prey animals, and prey are often faced with a trade-off between lowering their risk to predation and acquiring resources. This situation becomes more complex in a multi-predator landscape, especially if those predators employ different hunting strategies, and induce different spatial patterns of risk. READ MORE
