Age-dependent Effect of Environmental Light on Spectral Sensitivity and Body Colouration of Nile tilapia Oreochromis Niloticus
Hornsby, Mark (2012-12-06)Signal reception and production form the basis of animal communication, and are largely constrained by environmental biophysical factors such as environmental light. However, the role of environmental light in producing ... -
The Effect of Gonadotropin Releasing Hormone on Opsin Gene Expression and Spectral Sensitivity in Zebra Cichlid Fish (Metriaclima zebra).
Dedden, Ilse (2011-01-06)Sexual selection and the maintenance of species diversity in Lake Malawi cichlid fishes are greatly dependent on optical communication, which is influenced by environmental, physiological and endocrinological factors. The ... -
Functional Characterization of Teleost Intrinsic Photosensitive Dermal Chromatophores
Chen, Shyh-Chi (2013-08-27)Mammalians process their photoreceptions through lateral eyes; however, non-mammalian vertebrates and invertebrates possess additional extraretinal photoreceptors over their bodies to detect light stimuli. Chromatophores, ... -
Functional Diversity in Colour Vision of Fish
Sabbah, Shai (2012-05-14)The overall objective of this thesis was to understand better the mechanisms that shape the diversity in colour vision of fish, and to explore the adaptive significance of this divergence. Among the vertebrates, teleost ...
