Can redirected aggression explain interspecific attacks by Australian magpies on other birds?
(Brill, 2007)Attacks by participants of conflicts against a third party are referred to as redirected aggression. Usually the third party is a conspecific — few documented cases of redirected aggression against other species exist. The ... -
Comparing plasma and faecal measures of steroid hormones in Adelie penguins Pygoscelis adeliae
(Springer, 2010)Physiological measurements of both stress and sex hormones are often used to estimate the consequences of natural or human-induced change in ecological studies of various animals. Different methods of hormone measurement ... -
Conservation implications of song divergence between source and translocated populations of the North Island Kōkako
(Wiley, 2013)1. Translocation of individuals from healthy source populations to newly colonize or recolonize suitable habitat is a vital tool for the conservation of a species. Demographic, genetic and landscape factors, but also ... -
Converting predation cues into conservation tools: The effect of light on mouse foraging behaviour
(Public Library of Science, 2016)Prey face a conflict between acquiring energy and avoiding predators and use both direct and indirect cues to assess predation risk. Illumination, an indirect cue, influences nocturnal rodent foraging behaviour. New Zealand ... -
Do heterospecific size and demeanour influence visitation behaviour of birds at urban foraging patches?
(Springer, 2011)We compared the feeding behaviour of garden birds in the presence of four heterospecific decoy species at suburban feeding stations to assess the relative importance of body size (large vs. small) and demeanour (high vs. ...

The activity and functioning of the hypothalamic-pituitary-adrenal axis of the red deer stag (cervus elaphus)
(The University of Waikato, 2000)The activity and functioning of the HPA axis was investigated in red deer stags under basal and stress induced conditions. In order to overcome the confounding effects of stress inherent in standard methods of blood ... -
Habitat use and responses to odours by rodents in New Zealand
(The University of Waikato, 1999)Four species of introduced rodent live in New Zealand. No more than three species are sympatric here, although all four are in more tropical areas. All are pests for economic, public health and conservation reasons. The ... -
Sap feeding behaviour of North Island kaka (Nestor meridionalis septentrionalis, Lorenz 1896) in plantation forests
(The University of Waikato, 1996)North Island kaka (Nestor meridionalis septentrionalis) damage plantation pines (Pinus radiata and Pseudotsuga menziesii) in the Whirinaki Forest. Kaka strip pieces of bark off the trunks to gain access to the sap beneath. ... -
Relationships among male size, reproductive success, female choice and male advertising calls in Little Penguins (Eudyptula minor)
(The University of Waikato, 2002)The role of male acoustic features in the process of mate choice was investigated in Little Penguins (Eudyptula minor). Male call features and the calling behaviour may reveal important information on male attributes that ... -
The use of infrared thermography and behavioural and physiological responses as early disease indicators in calves
(The University of Waikato, 2020)Disease is widely acknowledged to be detrimental to an animal’s welfare and generates significant economic losses. To minimise the impact of disease on animal welfare and consequently reduce economic costs, early disease ...
