Paired T-tests between the two transects. These pair observations by timestamp and order within the transect. Any times/orders without paired data are thrown out.
The difference in means is relative to the Woods transect
The woods is 1.8 ºC cooler than the meadow
Paired t-test
data: temperature by transect
t = -26.222, df = 5819, p-value < 2.2e-16
alternative hypothesis: true difference in means is not equal to 0
95 percent confidence interval:
-1.968443 -1.694588
sample estimates:
mean of the differences
-1.831515
The woods is 3.4% more humid than the meadow
Paired t-test
data: humidity by transect
t = 21.041, df = 5820, p-value < 2.2e-16
alternative hypothesis: true difference in means is not equal to 0
95 percent confidence interval:
3.119606 3.760637
sample estimates:
mean of the differences
3.440122
The woods gets less light than the meadow by about 306 µmol/m^2/s
Paired t-test
data: pfd by transect
t = -56.304, df = 7214, p-value < 2.2e-16
alternative hypothesis: true difference in means is not equal to 0

-316.8756 -295.5530
sample estimates:
mean of the differences
-306.2143
The woods is drier than the meadow by about 0.13 m^3/m^3
