=========================================================================== Jackson ratio 不是針對Testudo屬烏龜的統計
而是Testudo graeca 和 Testudo hermanni野外統計下的結果
所以如果手上是別種龜種就不能使用
包括像豹龜 蘇卡達 折背 等一些熱帶不需要冬眠的龜種,
都不適用於這種圖表。
如Testudo horsfieldii Testudo marginata也不適用於Jackson ratio
理由如下:
This graph MUST NOT be used with Testudo horsfieldii or Testudo marginata, as
it will invariably produce incorrect results. The body shape of these species
is such that T. horsfieldii, being 'short and square' will tend to read
'overweight' even if it is actually underweight. T. marginata, being 'long
and narrow' will, on the other hand, read 'underweight' even if it is of a
perfectly average and safe weight for its size.
所以不是Testudo屬就可以用。
如果誤判很容易造成烏龜身體健康的錯覺,或是評估錯誤造成不適當的狀態下讓烏龜
冬眠而死於冬眠狀態下。通常在測量時,母龜體內有蛋,尿液糞便的囤積
,過食,過胖都會造成不在標準範圍的情形。
如果要使用這個表:http://www.tortoisetrust.org/articles/jacksonratio.pdf
我們姑且可以稱他為"歐洲陸龜和赫曼陸龜的生長體種比"
如果手上是別種烏龜的話
就要找文獻了的參考數值了
至於測量背甲的長度沒錯
但是要記得是頭到尾巴的垂直距離Straight Carapace Length (SCL)
不是包括背甲攏起的距離(CCL)
很多人都會誤用
要稍微注意一下
正確的量法如下:

如果要找不同龜種的量表,可以找找國外網站有心機的飼主,他們應該都有copy的。
