Lange, OL 1990: Twenty-three years of growth measurements on the crustose lichen Caloplaca aurantia in the central Negev Desert. - Israel Journal of Botany39: 383-394. [RLL List # 142 / Rec.# 11080] Keywords: NEGEV DESERT/ ISRAEL/ CRUSTOSE/ GROWTH RATE/ CALOPLACA/ DIPLOSCHISTES
Abstract: 6 figures. 1 table. ["It can be cautiously estimated that a Caloplaca aurantia thallus 10 cm in diameter near Avdat can be estimated to have an age of about 135 years. Because the largest thallus of this species found near Avdat can be estimated to have an age of about 500 years, it is certainly one of the oldest "individual" organisms in this area."]
