项目摘要
The purpose of this investigation was to quantitatively describe the colour patterns of the fiddler crab Uca capricornis and their ability to change on a socially significant timescale. Five experiments were conducted as part of this investigation, with fieldwork completed in East Point Reserve, Darwin (NT) from Nov. to Jan. in 04/05 and 05/06. The five experiments were: <br />
<br />
1) Quantifying colour patterns on the black carapace of the fiddler crab Uca capricornis- To examine the relationship between colouration, carapace size, and sex. This information was used to construct images illustrating the probable colour patterns of various groups of crabs.<br />
<br />
2) Colour changes associated with moulting - Cages were constructed and stocked with crabs which had been measured and photographed. In total 21 individuals (11 females, 10 males) were photographed through at least one moult. <br />
<br />
3) Colour changes associated with the semilunar cycle - During one semilunar cycle, from one neap tide to the next, digital photographs were taken of 22 crabs (10 males, 12 females) active in the cages at approximately low tide. Photos were examined to observe any colour changes on a day to day basis. <br />
<br />
4) Daily colour changes - Twenty-seven crabs (13 males, 14 females) were observed on the day after spring tide over several semilunar cycles. Digital photos of the crabs were taken before, during and after low tide. These photographs were examined for any changes in colour or pattern. <br />
<br />
5) Rapid colour changes - The ability of the crab to change colour over a 20 minute period was assessed using a portable spectrophotometer.
本次调查的目的是定量描述的招潮蟹Uca capricornis的颜色图案和他们的能力,以改变一个社会显着的时间尺度。作为本次调查的一部分,进行了五个实验,并于2005年11月至2006年1月在达尔文(NT)的东点保护区完成了实地调查。这五个实验是:<br />
<br />
1)量化的颜色模式上的黑色甲壳的招潮蟹Uca capricornis-检查之间的关系着色,甲壳大小和性别。这些信息被用来构建图像,说明各种螃蟹群体的可能颜色模式。<br />
<br />
2)与蜕皮有关的颜色变化-建造笼子,并放养螃蟹,这些螃蟹已经被测量和拍照。总共有21只个体(11只雌性,10只雄性)通过至少一次换羽进行拍照。<br />
<br />
3)与半月周期相关的颜色变化-在一个半月周期期间,从一个小潮到下一个小潮,拍摄了22只螃蟹(10只雄性,12只雌性)的数码照片,这些螃蟹在大约低潮时活跃在笼子里。每天检查照片以观察任何颜色变化。<br />
<br />
4)每日颜色变化----在几个半月周期内,在大潮后的第二天观察到27只螃蟹(13只雄性,14只雌性)。螃蟹的数码照片是在退潮前、退潮时和退潮后拍摄的。检查了这些照片的颜色或图案是否有任何变化。<br />
<br />
5)快速变色-使用便携式分光光度计评估螃蟹在20分钟内变色的能力。
