提供对招募和人口的有价值的见解一个线性回归模型被用来确定菲奥德兰人口的d3“amics的大小。从水下环境中拍摄的照片中获得的立体摄影测量所需的知识也将为研究许多离岸物种的生物学提供参考。经常受到C~nU~~不利影响的社会捕捞模型利用立体摄影测距Tice~(Probert et a1.S 1997)-深海拖网经常从一组物体空间控制点打捞出一个物体。一种深水珊瑚。不幸的是，将长温改正系数应用到立体摄影测量中，进行了测量研究，得到了改正测量。这项技术被用来研究一种特有物种的生长。在可疑湾，水生动物珊瑚Errina novaezelandiae的珊瑚生长测量技术，为生物学家提供了许多技术。结果表明，这种在珊瑚中生长的技术。用茜素或钙黄素活体染色，X的测量精度在95%的射线照相下为1.2毫米，而单帧摄影是一些置信度水平。我们发现，这些水生动物珊瑚有更常见的技术。简要讨论了这些技术的高侵蚀率，推测是由于放牧，而不是冰川，并提供了它们的优势和劣势之前报告过。下面。
provide valuable insights into the recruitment and population A linear regression model is used to determine the size of d3~"amics of the Fiordland population. Knowledge gained will correction required for stereophotogrammetric measurement also provide into the biology of many ~ffshore species, from photographs taken in an underwater environment. The which are often adversely affected by c~nu~~ercial fishing model utilizes the stereophotogrammetric distance measure- tice~ (Probert et a1.S 1997)- Deep-sea trawls frequently bring up ment of an object from a set of object-space control points. A deep-watercorals~ecies. Unfortunatel~j thelong-temeffecton correction factor is applied to the stereophotogrammetric these be studied measurement to obtain the corrected measurement. The technique was used to study the growth of an endemic species Exllng Coral Growth Measurement Techniques of hydrozoan coral, Errina novaezelandiae, in Doubtful Sound, A number of techniques are available to biologists for measurFiordland, New Zealand. The results show that the technique ing growth in corals. Vital staining with alizarin or calcein, Xhas a measurement accuracy of t 1.2 mm at the 95 percent ray radiography, and single-frame photography are some of the confidence level. We found that these hydrozoan corals have more common techniques. A brief discussion of these techa high erosion rate, presumably due to grazing, which was not niques and their advantages and disadvantages is provided reported previously. below.
