Skeletochronology (original) (raw)
La squelettochronologie est une méthode scientifique qui pour le biologiste permet l'estimation de l'âge des vertébrés. Elle est fondée sur les marques naturelles répétitives que forment les tissus osseux lors de leur croissance. La squelettochronologie est ainsi un peu pour les vertébrés ce que la dendrochronologie est pour les arbres.

| dbo:abstract | La squelettochronologie est une méthode scientifique qui pour le biologiste permet l'estimation de l'âge des vertébrés. Elle est fondée sur les marques naturelles répétitives que forment les tissus osseux lors de leur croissance. La squelettochronologie est ainsi un peu pour les vertébrés ce que la dendrochronologie est pour les arbres. (fr) Skeletochronology is a technique used to determine the individual, chronological ages of vertebrates by counting lines of arrested, annual growth, also known as LAGs, within Skeletal tissues. Within the annual bone growth specimens, there are broad and narrow lines. Broad lines represent the growth period and narrow lines represent a growth pause. These narrow lines are what characterises one growth year, therefore make it suitable to determine the age of the specimen. Not all bones grow at the same rate and the individual growth rate of a bone changes over a lifetime, therefore periodic growth marks can take irregular patterns. This indicates significant chronological events in an individual's life. The use of bone as a biomaterial is useful in investigating structure-property relationships. In addition to current research in skeletochronology, the ability of bone to adapt and change its structure to the external environment provides potential for further research in bone histomorphometry in the future. Amphibians and Reptiles are commonly aged determined, using this method, because they undergo discrete annual activity cycles such as winter dormancy or metamorphosis, however it cannot be used for all species of bony animals. The different environmental and biological factors that influence bone growth and development can become a barrier in determining age as a complete record may be rare. (en) Скелетохронология — метод, используемый для определения индивидуального возраста позвоночных путем подсчета так называемых ростовых слоёв в кальцифицированных частях скелета позвоночных животных. Метод широко используется в современных исследованиях возраста ныне живущих и вымерших животных. Термин «скелетохронология» был предложен Жаком Кастане в 1977 году для описания метода определения возраста по минерализованным скелетным элементам. Наибольшее распространение он приобрёл среди герпетологов и батрахологов. В ихтиологии и териологии обычно используют термин «регистрирющие структуры», так как определение возраста у рыб и млекопитающих чаще проводится по чешуе и зубам, не относящимся к скелету. (ru) |
