Potential variables forcing litterfall in a lower montane evergreen forest using Granger and superposed epoch analyses

The interplay between long-term environmental variability and litterfall is complex through this study, we quantified the response of peak leaf, flower, fruit production to such in a lower montane evergreen forest located Doi Suthep-Pui National Park, Thailand. We observed seasonality accumulation with leaf flower litterfalls occurring mostly during cool hot dry seasons, while occurs wet season. Probable associations drivers (barometric pressure, temperature, relative humidity, number sunlight hours, evaporation, wind speed, vapor pressure deficit) were tested on 5-year litter trap dataset using superposed epoch analysis Granger causality tests. tests indicated that significant deviations barometric maximum speed most plausible precursors all components. Additionally, lag climate by up 4 months for variables. Changing conditions can affect both timing amount production, which turn alter nutrient recycling rate other essential ecosystem services forests.
