Hello.
For a research project, I need the following information:
1. What is the most appropriate time of day and season to measure the light intensity of the forest floor? Does ambient temperature interfere with recording light intensity?
2. What quadrature size should we use for sampling plants and seedlings?
3. What software do you recommend for statistical analysis of the interaction of vegetation, light intensity, soil factors, litter depth, and soil organic and mineral elements?
Measure at different times of the day to obtain a range of light intensity on the forest floor. You can measure temperature at the same time to see if there is a correlation. For seedlings, you can use 1 square metre quadrats, but for tree species, 25 square metres. And something in between for seedling combined with saplings. Your statistical test could be PERMANOVA or a General Additive Model :)
