Phospholipid Fatty Acid (PLFA-microbial) assay (membrane biochemical markers, gives a view into community composition) Analyzed using Principle Components Analysis (PCA) Microbial community analysis Honeysuckle samples at 1 month differentiate from native species Microbial community dynamics
-Throughout the decomposition sequence, L. maackii remains distinct. -Microbial succession? Microbial community dynamics
Honeysuckle leaf breakdown was 4-5x faster compared to native leaf packs (P < 0.01) Fig. 1 Linear regression models of ln leaf material remaining (as AFDM) over ADD to determine decay coefficients (k) for native, invasive and mix leaf packs in three 3 rd order steams of southwestern Ohio, USA. Letter comparisons are between treatments and were from one-way ANOVA analyses based on mean, sample size, and standard error from linear regression models Fig. 4: Leaf litter remaining for leaf packs composed of L. maackii, native, and a L. maackii-native mix in three headwater streams of southwestern Ohio. Significant differences of Bonferroni post-tests (P < 0.05) after two- way ANOVA are represented with different letters between treatments within each sampling day.
Gathering-Collectors significantly dominated the FFG within L. maackii leaf packs (P < 0.01) There were differences in the abundance pattern of FFG between leaf pack treatments Aquatic macroinvertebrate functional feeding group colonization of L. maackii, mix and native leaf packs in 3 headwater streams.
