Role of urinary and cloacal bladders in chelonian water economy: historical and comparative perspectives
Article Abstract:
Tortoises and terrestrial amphibians are the only vertebrates to have large urinary bladders that can act as water reservoirs during periods of drought while also storing K+ and nitrogenous waste. The water reservoir function works if urine voiding is discontinued while there is no water and if an excessive amount of water is taken on board while available. The rate of metabolic water production does not differ from water intake rates during summer drought periods, with urine stored in the large bladder instead of being voided.

An extract from 'Memories for Family and Friends.' (evolutionary biology professor's perspective on animal development and behavior)
Article Abstract:
A professor of ecology and evolutionary biology at Princeton University describes his perspective on the development of plants and animals. He also recounts his experiences during a visit at the University College in London, where he was invited to give three lectures. During his stay in the UK, he met Halden Spurway and his wife Helen. They would often meet to discuss about animal behavior and its evolutionary implications. His meetings with the Spurways led to a sporadic correspondence with the couple.
