Growth of the desert tortoise (Gopherus agassizi) in Nevada
Between 1963 and 1973, growth of the desert tortoise (Gopherus agassizi) in southern Nevada averaged about 9 mm per year. Yearly increments were estimated for 5 years (1969 to 1973) and ranged from a low of 1.8 mm in 1972 to a high of 12.3 mm in 1969. Growth was greatest following winters of high precipitation, which resulted in increased production of winter annuals in the spring. Growth of tortoises generally occurred between April and July. The weight, W(g), of tortoises may be estimated as W =0.000258X/sup 2.98/ with X the plastron length in mm. (auth)
