The use of anticoagulant rodenticides to eradicate invasive rodents from islands has become a powerful tool to prevent species extinctions and to restore degraded ecosystems. Success is dependent on all targeted individuals consuming rodenticide and

Diving and foraging behaviours of marine predators are thought to be coupled with species demographics, with benthic foraging species found to have small population sizes and low growth rates. This was thought to be the case for New Zealand (NZ) sea

Parasites can have both direct and indirect impacts on organisms through changes in health, growth, reproductive success, behaviour and survival. This research investigates the effects of hookworms (Uncinaria sp.) on the growth and mortality of New Z
