Calculation of abundance of Stonefly Nymphs in relation to riffles and poles in rivers. Spelling!
Problem: How do temperature, depth and velocity of water in Rifles and Poles affect the abundance of Stonefly Nymphs? Link to course and why did you choose this topic?
Background
The point of this analysis is to compare the abundance of Stonefly Nymphs in rifles vs. Poles. EXPLAIN
The Plecoptera are an order of insects, commonly known as stoneflies. There are around 3,500 species worldwide, with new species still being discovered. Plecoptera are found in both the Southern and Northern Hemispheres and the populations are quite distinct. All species of Plecoptera are intolerant of water pollution and their presence in a stream or still water is usually an indicator of good or excellent water quality. Stoneflies are …show more content…

Null Hypothesis: There is no statistically significant difference in the abundance of Stonefly Nymph between Pools and Riffles.

Stonefly Nymphs live in highly oxygenated, cool, clean and flowing waters, some preferring streams with a significant current on rocky, stony, or gravel substrate. Some even live in sandy areas. Rifles and poles are both strong in certain distinct abiotic factors presented which could mean that one would be likely to present favourable conditions for Stonefly Nymphs than the other. The following analysis will put that theory in to test to see if there is in fact a statistically significant difference in between the two or if there is not.

Independent Variables: Abundance of Stonefly Nymphs
Dependant Variables: Temperature (°C); Velocity (Ms); Depth (Cm)

    Carefully describe what the p-value tells you about the difference between the means. - The average number of phytoplankton per mL of water is 13 phytoplankton/mL of water, and the average of zooplankton is 41 zooplankton/mL of water. The 2SE for phytoplankton is 11, for zooplankton it is 21. The p-value for this data is 0.0255; because this p-value is less than 0.05 one can conclude that the difference in averages (i.e. zooplankton being higher than average of phytoplankton) is statistically significantly different. In other words, the greater average number of zooplankton per mL is very unlikely to be due to chance variation and likely due to some outside

    Students started off with a population of ten Skittlefish (skittles) on an orange reef (construction paper). The skittles had varying colors, and the adaptive trait being examined was the ability to blend in with the reef so the predators would not find them. The hypothesis that was thought up was that individuals’ survival was based on their location and coloring. The first year began with two of each color, and 5 Skittlefish were eaten that “year”. The ones eaten were two green, two purple, and one red.
