From: Land use alters cross-ecosystem transfer of high value fatty acids by aquatic insects
Modeled seasonal patterns of fatty acid (FA), saturated fatty acid (SFA), monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA) export from streams of aquatic insect orders. The values were derived with hierarchical generalized additive models (HGAM) fitted with 998 observations. Solid lines represent the predicted mean fit values of the HGAM, and the ribbon shows ± 2 standard errors around the mean fit. Dots indicate significant differences (non-overlapping 95% confidence intervals at alpha = 0.05) between agricultural and forested sites. Blue shows the seasonal patterns in agriculture and green in forest for a, e, i, m mayflies, b, f, j, n non-biting midges, c, g, k, o caddisflies, and d, h, l, p stoneflies. Seasons: spring: 18th March–16th May, summer: 17th May–26th July, autumn: 27th July–13th September. Beware that the y-axis scale varies
