Department of Zoology, University of Western Australia, Nedlands, Western Australia 6907, Australia
J Comp Neurol 412:203-17. 1999..These results demonstrate that an established photoreceptor mosaic of rows of single cones can be reorganised to form a regular square mosaic composed of single and double cones...
Variability in the location of the retinal ganglion cell area centralis is correlated with ontogenetic changes in feeding behavior in the black bream, Acanthopagrus butcheri (Sparidae, teleostei)J Shand
Department of Zoology, University of Western Australia, Nedlands, Australia
Brain Behav Evol 55:176-90. 2000....
The relationship between the position of the retinal area centralis and feeding behaviour in juvenile black bream Acanthopagrus butcheri (Sparidae: Teleostei)J Shand
Department of Zoology, The University of Western Australia, Nedlands, Australia
Philos Trans R Soc Lond B Biol Sci 355:1183-6. 2000..The AC of a fish (51 mm SL) preferentially taking food from the substrate was located in a dorsal position...
Retinal development of West Australian dhufish, Glaucosoma hebraicumJ Shand
Department of Zoology, University of Western Australia, Crawley
Vis Neurosci 18:711-24. 2001..The results imply that the larvae and juveniles are adapted for survival in coastal waters and may be active in relatively low light levels from early stages of development...
Developmental changes in the cone visual pigments of black bream Acanthopagrus butcheriJulia Shand
Department of Zoology, University of Western Australia, WA 6009, Australia
J Exp Biol 205:3661-7. 2002....
The influence of ontogeny and light environment on the expression of visual pigment opsins in the retina of the black bream, Acanthopagrus butcheriJulia Shand
School of Animal Biology, University of Western Australia, Crawley, WA 6009, Australia
J Exp Biol 211:1495-503. 2008....
Trichromacy in Australian marsupialsCatherine A Arrese
Department of Zoology WAIMR, University of Western Australia, WA 6009, Crawley, Australia
Curr Biol 12:657-60. 2002..It is the first evidence for the basis of trichromatic color vision in mammals other than primates. We suggest that Australian marsupials have retained an ancestral visual pigment that has been lost from placental mammals...
Cone topography and spectral sensitivity in two potentially trichromatic marsupials, the quokka (Setonix brachyurus) and quenda (Isoodon obesulus)Catherine A Arrese
School of Animal Biology, University of Western Australia, 35 Stirling Highway, Crawley 6009, Australia
Proc Biol Sci 272:791-6. 2005..The presence of three cone types, along with previous findings in the fat-tailed dunnart and honey possum, suggests that three spectrally distinct cone types are a feature spanning the marsupials...
Topographies of retinal cone photoreceptors in two Australian marsupialsC A Arrese
School of Animal Biology, University of Western Australia, Crawley 6009, Australia
Vis Neurosci 20:307-11. 2003..A low number of cones remained unlabeled when the antisera were combined revealing further minority cone population(s). We discuss cone distributions in relation to visual capabilities and requirements of the species...
Retinal characteristics of the ornate dragon lizard, Ctenophorus ornatusHelen R Barbour
Department of Zoology, University of Western Australia, Crawley WA 6009, Australia
J Comp Neurol 450:334-44. 2002..The presence of a fovea containing slender cone photoreceptors and three visual pigments suggests that the lizard has high acuity and the potential for color vision...
The rod opsin pigments from two marsupial species, the South American bare-tailed woolly opossum and the Australian fat-tailed dunnartDavid M Hunt
Division of Molecular Genetics, Institute of Ophthalmology, University College London, Bath Street, EC1V 9EL, London, UK
Gene 323:157-62. 2003..From microspectrophotometric measurements, the pigments in the two species show an 8 nm difference in peak absorbance; the molecular basis for this spectral shift is discussed and two candidate substitutions are identified...

Circadian and Visual Neuroscience, Wellcome Trust Centre for Human Genetics, University of Oxford, Roosevelt Drive, Oxford OX3 7BN, UK
Proc Biol Sci 274:2791-9. 2007..This approach reveals that the two marsupials show a higher sequence identity than that seen between rodents and primates, despite separating at approximately the same point in time, some 65-85 Myr ago...

Department of Anatomy and Developmental Biology, School of Biomedical Sciences, The University of Queensland, Brisbane 4072, Queensland, Australia
Vis Neurosci 20:119-30. 2003..The functional significance of the unique visual system of Geotria is discussed in relation to its life cycle and the potential for color vision...
