Top predators as biodiversity regulators: the dingo Canis lupus dingo as a case study.

摘要: Top-order predators often have positive effects on biological diversity owing to their key functional roles in regulating trophic cascades and other ecological processes. Their loss has been identified as a major factor contributing the decline of biodiversity both aquatic terrestrial systems. Consequently, restoring maintaining function top is critical global imperative. Here we review studies dingo Canis lupus dingo, Australia's largest land predator, using this case study explore influence predator at continental scale. The was introduced Australia by people least 3500 years ago an ambiguous status its brief history continent, adverse impacts livestock production role ecosystem architect. A large body research now indicates that dingoes regulate cascades, particularly arid Australia, removal results increase abundances herbivores invasive mesopredators, most notably red fox Vulpes vulpes. linked widespread losses small medium-sized native mammals, depletion plant biomass due irrupting herbivore populations increased predation rates foxes. We outline suite conceptual models describe vertebrate across different Australian environments. Finally, discuss issues require consideration or warrant before can be incorporated formally into conservation programs.
