Aggressive transition between alternative male social tactics in a long-lived Australian dragon (Physignathus lesueurii) living at high density by Baird, Troy A, Baird, Teresa D, Shine, Richard

“…Theory predicts the evolution of alternative male social tactics when intense competition coupled with the superior competitive ability of some individuals…”

Live fast and prosper: early territory defence is not costly in male collared lizards (Crotaphytus collaris) by Baird, Troy A

“…Abstract Males often exhibit subordinate social tactics and grow at high rates when young, but changes in local social conditions may accelerate opportunities…”

Is Melanism a Consequence of Sexual Selection in Male Red-Eared Sliders, Trachemys scripta elegans? by Stone, Marie E. B, Baird, Troy A, Stone, Paul A

“…Male slider turtles change coloration ontogenetically, becoming melanistic as they age and approach the body size of sexually mature females. Several…”

An experimental field test of female defense in territorial male collared lizards by Baird, Troy A, Leibold, Dalton C

“…Abstract A widely held principle in behavioral ecological research is that polygynous social systems evolve either by direct male defense of females or male…”

Does courtship behavior predict parentage in Collared Lizards? Influence of male social status and habitat structure by Baird, Troy A., York, Joshua R.

“…Incorporating microsatellite techniques to determine parentage is a powerful addition to behavioral mating system studies in wild animals. Nonetheless, in some…”

Male collared lizards, Crotaphytus collaris (Sauria: Crotaphytidae), signal females by broadcasting visual displays by Baird, Troy A.

“…The signalling function of displays broadcast when animals are distant from conspecifics can be difficult to determine. I tested the extent to which visually…”

Heightened aggression and winning contests increase corticosterone but decrease testosterone in male Australian water dragons by Baird, Troy A., Lovern, Matthew B., Shine, Richard

“…Water dragons (Intellegama [Physignathus] lesueurii) are large (to >1m) agamid lizards from eastern Australia. Males are fiercely combative; holding a…”

Testing the adaptive significance of sex‐specific mating tactics in collared lizards (Crotaphytus collaris) by York, Joshua R, Baird, Troy A

“…We tested whether territorial defence is adaptive in male collared lizards by examining the extent to which territory owners monopolize females. We also tested…”

Collared Lizard Juveniles Use Caudal Displays while Stalking Prey by Braun, Cody A, Baird, Troy A

“…Caudal displays that lure or divert the attention of prey are well documented in legless squamates that use sit-and-wait foraging. By contrast, empirical…”

Juvenile Collared Lizards Adjust Tail Display Frequency in Response to Variable Predatory Threat by York, Joshua R, Baird, Troy A, Ebensperger, L

“…Antipredator behavioral tactics have evolved in phylogenetically diverse animal clades and often involve prey initiating conspicuous display patterns when…”

Unexpected high fitness payoff of subordinate social tactics in male collared lizards by York, Joshua R., Baird, Troy A., Haynie, Michelle L.

“…Sexual selection theory often predicts that dominant males will sire more offspring than males displaying subordinate social tactics. We combined the records…”

Tail waving in a lizard ( Bassiana duperreyi) functions to deflect attacks rather than as a pursuit-deterrent signal by Telemeco, Rory S., Baird, Troy A., Shine, Richard

“…Antipredator tactics that promote survival should be under strong selection. Therefore, apparently ‘risky’ behaviours should only be stably maintained in a…”

Thermal effects on reptile reproduction: adaptation and phenotypic plasticity in a montane lizard by TELEMECO, RORY S., RADDER, RAJKUMAR S., BAIRD, TROY A., SHINE, RICHARD

“…Interspecific comparisons suggest a strong association between cool climates and viviparity in reptiles. However, intraspecific comparisons, which provide an…”

A growth cost of experimentally induced conspicuous coloration in first-year collared lizard males by Baird, Troy A.

“…I used painted first-year collared lizard males in the field to test the hypothesis that conspicuous coloration imposes a growth cost, either because it makes…”
