Lizards choose perches non randomly
Effective visual crypsis requires that animals behave in a manner consistent with their camouflage. Individuals who employ background-matching strategies are
Zebra finches and heterospecific alarm calls
Studies have shown that numerous species eavesdrop on the calls of heterospecifics to gain information about predator presence. Responding to
Cryptic lizards
Effective visual crypsis requires that animals behave in a manner consistent with their camouflage. Individuals who employ background-matching strategies are
Dancing frogs
In this project, we aim to examine the multimodal communication of an Australian anuran species, Litoria fallax (the eastern sedge

Zebra finches don’t alarm call
Many vertebrates use vocalizations to communicate about the presence of predators, and some encode information about predator type or behaviour.
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
