“…Selain itu, tumbuhan bawah juga berpengaruh terhadap keberadaan mikroflora dan meningkatkan pelapukan mineralmineral di dalam tanah (Augusto et al 2002;Qiao et al 2014). Tumbuhan bawah dapat berfungsi dalam peresapan dan membantu menghalangi jatuhnya air hujan secara langsung, sehingga dapat mencegah erosi yang berlangsung secara cepat (Maisyaroh 2010;Hilwan et al 2013;Jiang et al 2022). Oleh karena itu, data tumbuhan bawah dan cadangan biji menjadi penting dalam studi ekologi komunitas.…”

The 2010 eruption of Mount Merapi caused the ecosystem of Mount Merapi National Park had damage. The recovery of the surrounding ecosystem was called succession . Soil seed bank can be a seed resource for the succession. This research was conducted to analyze vegetation composition and explore the potential seed bank of understorey plants. The vegetation analysis was done using a quadratic method in the three locations: highly damaged, moderately damaged, and lightly damaged. A 1×1 m2 plot was used to collect 9 soil samples from each location. The soil samples were stored in a greenhouse for the germination test. Results showed that Poaceae dominated the vegetation in three locations. The vegetation in moderately and lightly damaged locations has a higher score in diversity and evenness than that in highly damaged locations. The seed bank results showed approximately 34 understorey plants from 14 families dominated by Poaceae. The similarity between the standing aboveground vegetation and soil seed banks in the three locations was low.

Differential Responses of Sap Flow to Environmental Factors Under Contrasting Rainfall Amounts During the Rainy Season in a Boreal Birch Forest

Sap flow dynamics are critical for understanding how vegetation consumes water and adapts to environmental stress. The response of sap flow in boreal birch secondary forests to rainfall variations during the rainy season, however, has been inadequately explored. Our study indicated that photosynthetically active radiation (PAR) and vapour pressure deficit (VPD) are the primary drivers of sap flow density in birch trees across different diameter classes (Fds: small trees, Fdm: medium‐sized trees, Fdl: large trees). Soil water content (SWC) significantly reduces sap flow when it falls below the 0.18 cm3/cm3. Sap flow density increased with PAR and initially with VPD but plateaued at higher VPD levels due to saturation. A hierarchy of sap flow density was observed, with Fdl > Fdm > Fds, each responding differently to PAR, VPD and SWC. With decreasing rainfall across rainy seasons, the influence of PAR on Fds and Fdm weakened, while the influence of VPD strengthened. For Fdl, the impact of VPD peaked and then declined, while the influence of PAR showed an inverse pattern. In the dry season, Fdl was primarily driven by PAR and influenced by VPD and SWC, whereas Fds was mainly controlled by VPD, with minimal effects from PAR and SWC. The response of Fdm to SWC was similar to that of Fdl, but it mirrored the response of Fds to PAR and VPD. These findings suggest that sap flow in boreal birch forests may become increasingly susceptible to SWC stress as global climate change intensifies.
