Control Strategies in Guanine Biocrystallization

Angewandte Chemie, EarlyView.
Biological guanine crystals produce spectacular photonic phenomena in animals and hold great promise as new, sustainable optical materials. We review how organisms precisely control the structure, morphologies, and resulting optical properties of these crystals using a set of ingenious ‘design’ strategies, including control of pH, template‐directed ...

Dynamic social networks in guppies (Poecilia reticulata) [PDF]

Behavioral Ecology and Sociobiology, 2014
One of the main challenges in the study of social networks in vertebrates is to close the gap between group patterns and dynamics. Usually scan samples or transect data are recorded to provide information about social patterns of animals, but these techniques themselves do not shed much light on the underlying dynamics of such groups.

Tetrahymena Infection in Guppy, Poecilia reticulata.

Fish Pathology, 2000
Out of 78 diseased guppies imported from Singapore to Japan, 43 fish were found infected with ciliates. Thus, pathological examination of guppies naturally infected with ciliates and identification of a ciliate sampled from guppies in Singapore were conducted. Most of the ciliates parasitized the inside of scales, muscles or internal organs, while some
