Comparative chemical ecology, behaviour, and evolutionary genetics of acanthodactlylus boskianus (Squamata: Lacertidae) : comparative chemical ecology, behaviour and evolution
… and signal evolution of A. boskianus. These are behaviour, chemical and DNA analyses techniques.Behavioural bioassays in different experiments showed that the femoral gland secretions are used in communication between the lizards. Communication includes possible roles in mate choice, agonistic …

The role of territoriality in the mating system of the springbok Antidorcas marsupialis (Zimmerman 1780)
… the two sexes within herds was modified by the agonistic behaviour of territorial males, which was lowest during the rut and highest at the end of the dry season. Territories were maintained through the year, despite the restricted breeding periods. Territory take-up and loss were related to …

Investigating trade-offs in Strength, Skill and Vigour in Pagurus Bernhardus
… very little about how it affects fighting <br/>behaviour or other RHP traits. Using the European hermit crab Pagurus <br/>bernhardus, we investigated the relationship between three RHP traits: <br/>strength, vigour and skill. We identified a potential trade-off between strength <br/>and skill, …

Social suppression of reproduction in the naked mole-rat, Heterocephalus glaber : -Plasma LH concentrations and differential pituitary responsiveness to exogenous GnRH
… non-breeding animals by preferentially directing agonistic behaviour towards those animals that pose the greatest threat to her reproductive supremacy. Previous studies have investigated the phenomenon of reproductive suppression in the naked mole-rat, and have compared breeding and non-breeding …

Behavioural interactions and reasons for aggression between Australian magpies (Gymnorhina tibicen) and other birds in New Zealand
… to determine the extent and context of this behaviour, and (2) examine potential explanations for the interspecific aggression displayed by magpies. Accounts of magpie attacks on birds in New Zealand were collated from literature and a survey of the public, and then summarised to identify the …

In Trial A, tail presence did not significantly increase the risk of tail lesions, the level of acute phase proteins (i.e. blood markers of inflammation), or impair the health status (mortality, lung …

The fluvial biology of Lake Taupo rainbow trout
… in these stocks of fish. Genetic differences in agonistic behaviour were also investigated in laboratory incubated juvenile rainbow trout from the Waimarino and Tokaanu Rivers. Because of the small sample sizes involved in this experiment, the results are considered to be only preliminary. …
