Avec l\u2019extension de ses populations dans une grande partie de l’Europe, la surveillance des castors eurasiens (Castor fiber<\/em>) devient de plus en plus n\u00e9cessaire. C\u2019est dans ce cadre qu\u2019une \u00e9tude men\u00e9e en Norv\u00e8ge a examin\u00e9 la pr\u00e9cision de l’identification et de l’\u00e9valuation de l’\u00e2ge des castors \u00e0 partir de photographies de la queue. En effet, cette m\u00e9thode non invasive de d\u00e9termination de l’\u00e2ge des castors \u00e0 partir de la couleur de la queue (la couleur devenant plus claire au fur et \u00e0 mesure que le castor vieillit) existe d\u00e9j\u00e0, mais est bas\u00e9e sur des observations de castors d’Am\u00e9rique du Nord. Comme ils sont morphologiquement similaires, les chercheurs s\u2019attendaient \u00e0 ce qu’une tendance similaire soit observ\u00e9e chez le castor d’Eurasie.<\/p>\n

Les chercheurs ont utilis\u00e9 un \u00e9chantillon important de photographies venant d\u2019un site de la r\u00e9gion de Telemark, qui abrite aujourd’hui le \u00ab Norwegian Beaver Project \u00bb, l’un des plus anciens projets sur le castor, qui a d\u00e9but\u00e9 en 1997. Ils ont \u00e9tudi\u00e9 deux caract\u00e9ristiques : le motif des \u00e9cailles et la couleur de la queue.<\/p>\n

Les r\u00e9sultats sugg\u00e8rent que cette m\u00e9thode pourrait \u00eatre utilis\u00e9e comme m\u00e9thode non invasive d’identification individuelle pour le suivi des populations de castors car la pr\u00e9cision de l’identification individuelle est de 100 %. Cependant, la m\u00e9thode est inefficace pour \u00e9valuer l’\u00e2ge des castors.<\/p>","protected":false},"excerpt":{"rendered":"
