Effective visual crypsis requires that animals behave in a manner consistent with their camouflage. Individuals who employ background-matching strategies are

Interspecific variation in motion displays
Signaling species occurring in sympatry areoften exposed to similar environmental constraints, so similar adaptations to enhance signal efficacy are expected.
Anolis signals & local adaption
For animals to communicate effectively, signals are required to be successfully detected by an intended receiver across the extent of
Anolis signals & species recognition
Visual signalling is used during inter and intra specific interactions, and has evolved toward complex, diverse and highly species-specific displays.
Co-ocurrence of Ecuadorian Anolis
Species aggregations within communities can be influenced by several processes, which operate over different spatial and temporal scales. We sampled
Retreat site selection of Anolis lizards
We investigated variation in nocturnal ambient temperature of the landscape, the nocturnal body temperature, and retreat site utilisation of restricted,
Quantifying ecological constraints on motion signaling
The environment in which animal signals are generated has the potential to affect transmission and reliable detection by receivers. To
Intraspecific variation in motion displays
Habitat characteristics influence the efficacy of animal communication, and population differences insignal structure due to habitat variation are well known
Social context and tail displays by Chinese dragons
Competition between animals for limited resources often involves signaling to establish ownership ordominance. In some species, the defended resource relates
NSFC Funding
The National Natural Science Foundation of China awarded our collaborator Dr Qi Yin the equivalent of $140,000 for studies of
Australian dragons: motion displays
Australia’s dragon lizards (Family: Agamidae) employ dynamic visual signals in a variety of contexts but the signalling behaviour of this

Many thanks to the National Geographic Society for providing US$18580 in support of our work on Anolis lizards in Ecuador: Habitat structure, competition
Chinese dragons
Territorial behaviour in animals arises when animals compete for an area of space that contains valuable resources. In many species,
Virtual Lens
Motion vision is crucial in the life of animals, in controlling locomotion, in foraging, for predator evasion and incommunication. However,
