Document Summary
Can try to y place over top and count them. Or take a pic and use software to count them both of these are bad as well. What you should do is pick a quadrant where the density looks pretty even and count the amount in this quadrant and then repeat this over other similar quadrants. This is easy with amingos b/c they are light coloured on a dark background however, it usually does no work out like this and is much more complicated. Population w patchy densities are hard to sample with randomly thrown quadrants b/c you could miss species patches every time. Thus, you must do it in a strati ed random way (divide area up based on pop density) [usually need to use this method for most real world cases] So where do you put the quadrants? either random or strati ed random. This works well only for organisms who do not move around (are sessile)
