Social complexity as a proximate and ultimate factor in communicative complexity
- T. Freeberg, R. Dunbar, T. J. Ord
- Psychology, Medicine
- Philosophical Transactions of the Royal Society B…
- 5 July 2012
The ‘social complexity hypothesis’ for communication posits that groups with complex social systems require more complex communicative systems to regulate interactions and relations among group… Expand
Lizards speed up visual displays in noisy motion habitats
- T. J. Ord, R. A. Peters, Barbara Clucas, J. Stamps
- Biology, Medicine
- Proceedings of the Royal Society B: Biological…
- 22 April 2007
Extensive research over the last few decades has revealed that many acoustically communicating animals compensate for the masking effect of background noise by changing the structure of their… Expand
Digital video playback and visual communication in lizards
- T. J. Ord, R. A. Peters, C. S. Evans, A. Taylor
- Psychology
- Animal Behaviour
- 1 May 2002
Experimental analyses of dynamic visual signals have to overcome the technical obstacle of reproducing complex motor patterns such as those found in courtship and threat displays. Video playback… Expand
Tracing the origins of signal diversity in anole lizards: phylogenetic approaches to inferring the evolution of complex behaviour
- T. J. Ord, E. Martins
- Biology
- Animal Behaviour
- 1 June 2006
Within species, natural and sexual selection work together to shape the design of animal communicative systems, and sometimes act differentially on alternate components to produce a single elaborate… Expand
Interactive video playback and opponent assessment in lizards
- T. J. Ord, C. S. Evans
- Psychology, Medicine
- Behavioural Processes
- 30 August 2002
Video playback has been used to explore many issues in animal communication, but the scope of this work has been constrained by the lack of stimulus-subject interaction. In many natural contexts,… Expand
Repeated evolution and the impact of evolutionary history on adaptation
- T. J. Ord, Thomas C. Summers
- Biology, Medicine
- BMC Evolutionary Biology
- 10 July 2015
BackgroundWhether natural selection can erase the imprint of past evolutionary history from phenotypes has been a topic of much debate. A key source of evidence that present-day selection can… Expand
Sexual selection, natural selection and the evolution of dimorphic coloration and ornamentation in agamid lizards
- D. Stuart-Fox, T. J. Ord
- Biology, Medicine
- Proceedings of the Royal Society of London…
- 7 November 2004
Both sexual selection and natural selection can influence the form of dimorphism in secondary sexual traits. Here, we used a comparative approach to examine the relative roles of sexual selection and… Expand
Alert signals enhance animal communication in “noisy” environments
Environmental noise that reduces the probability that animals will detect communicative signals poses a special challenge for long-range communication. The application of signal-detection theory to… Expand
CONTRASTING THEORY WITH THE EMPIRICAL DATA OF SPECIES RECOGNITION
- T. J. Ord, Léandra King, A. Young
- Biology, Medicine
- Evolution; international journal of organic…
- 1 September 2011
We tested hypotheses on how animals should respond to heterospecifics encountered in the environment. Hypotheses were formulated from models parameterized to emphasize four factors that are expected… Expand
Species Identity Cues in Animal Communication
Researchers have suggested that animals should respond more strongly to conspecific than to heterospecific communication signals used in territorial or courtship contexts. We tested this prediction… Expand
