“…However, variations in microclimate among studies have resulted in a mechanistic understanding and, thus, underdeveloped knowledge of what controls the decomposition process (Li et al 2020). These variations in site conditions are addressed using intersite experiments, which allow researchers to explore how site-specific factors influence decomposition across diverse environmental and site conditions (Park et al 2021). To the best of our knowledge, however, in-situ decomposition experiments are poorly explored due to logistical constraints and complexities of monitoring decomposition patterns in tropical settings.…”

“…Litter quality, such as biochemical composition (e.g., nutrient concentration) and physical structure (e.g., specific leaf area (SLA)), corresponds to nutritional value, palatability, and digestibility for decomposers (Barbe et al 2017). Some studies reported that the presence of high lignin content and SLA may either accelerate or impede the decomposition process, depending on the concentration of nitrogen (N), phosphorus (P), and the lignin: N ratio in litter (Park et al 2021;Yan et al 2020). Moreover, litter from evergreen tree species decomposes slower than that from deciduous trees due to higher toughness, lower nutrient content, and higher concentrations of structural phytochemicals (Lidman et al 2017).…”

Litter traits and site conditions alter nutrient inputs from deciduous and evergreen forests by influencing litter decomposition processes. Here, we investigated the leaf and stem mass loss rate (MLR) of a deciduous (Tectona philippinensis) and an evergreen (Parashorea malaanonan) tree species and the factors influencing it through an intersite experiment and litterbag method in secondary forests in Lobo, Batangas and Mount Makiling Forest Reserve (MMFR). Variations in initial litter quality (leaf area, specific leaf area (SLA), leaf thickness, vein density), and site factors (light intensity and temperature) were assessed. P. malaanonan has a lower SLA and vein density than T. philippinensis. The leaf and stem MLR were significantly higher in the mixed litter (44.09–57.83%) than that of a single-species litter of either T. philippinensis (28.16–41.83%) or P. malaanonan (33.60–47.66%). The leaf MLR of T. philippinensis was greater when placed in Lobo (where the litter originated) than at a different site (i.e., MMFR). Moreover, leaf litter decomposition was faster in T. philippinensis than in P. malaanonan, particularly during the rainy season. Overall, the study showed that litter decomposition in deciduous and evergreen differed across sites due to variations in litter quality and environmental variables.

“…Drought stress has adverse effects on plant growth and development, affecting both morphology and physiology ( Park et al, 2021 ; Wahab et al, 2022 ). These effects are primarily linked to carbon allocation, which has implications for leaf carbon balance ( Körner, 2003 ; Allen, Breshears & McDowell, 2015 ).…”

Background The impacts of climate change, such as increased soil dryness and nutrient deficiency, highlight the need for environmentally sustainable restoration of forests and groundwater resources. However, it is important to consider that extensive afforestation efforts may lead to a depletion of groundwater supply due to higher evapotranspiration rates, exacerbating water scarcity issues. Consequently, we conducted a study to examine how the fast-growing tree species Populus sibirica (Horth ex Tausch) and Ulmus pumila (L.) respond morpho-physiologically to varying watering regimes and types of fertilizers, aiming to better understand their specific water and nutrient requirements. Methods We used two-year-old nursery-growth seedlings (N = 512) of P. sibirica and U. pumila with initial root collar diameter (RCD) and the height of 0.51 ± 0.02 mm and 68 ± 2.94 cm and 0.33 ± 0.01 mm and 51 ± 1.14 cm, respectively. The leaf area (LA), specific leaf area (SLA), chlorophyll concentration, stomatal conductance (gs), chlorophyll fluorescence, and predawn and midday leaf water potential were measured across treatments. Four different irrigation regimes and two different fertilizer types were applied: no irrigation (control, 0 L h−1), 2 L h−1 = 0.25 mm m−2, 4 L h−1 = 0.5 mm m−2, 8 L h−1 = 1.0 mm m−2 and 120 g and 500 g tree−1 of NPK and compost (COMP). Twelve plots (600 m2) were established in the study site for each species and treatments. Results During the first growing season (2021), the LA of P. sibirica was larger in the 4–8 L h−1 without fertilizer, but it was smaller in the 4 L h−1+ COMP during the second growing season (2022). The 2 L h−1 without fertilizer and 2 L h−1 + NPK had larger LA compared with the control (CONT) for the first and second growing seasons, respectively, for U. pumila. P. sibirica seedlings at 4 L h−1 without fertilizer had the highest SLA for 2021 and at 2 L h−1 + NPK for 2022, whereas CONT and 4 L h−1 had the highest SLA than the other treatments for 2021 and 2022 growing seasons, respectively, for U. pumila. The chlorophyll concentration of P. sibirica seedlings in the first year was generally higher in CONT, while the 2 L h−1 without any fertilizer yielded a significantly higher chlorophyll concentration of U. pumila. Chlorophyll fluorescence parameters (PIABS and Fm) were generally lower in CONT with/without NPK or COMP for both species. The CONT with NPK/COMP generally had a higher gs compared with the other treatments in both experimental periods for U. pumila, whereas CONT and 2 L h−1+ NPK-treated P. sibirica seedlings had a significantly greater gs during the first year and second year, respectively. The predawn and midday leaf water potentials of both species were generally the lowest in CONT, followed by 2 L h−1+ NPK/COMP during the first growing season, but a different pattern was observed during the second growing season. Overall, the morpho-physiological traits of the two species were affected by watering and fertilizer treatments, and the magnitude of the effects varied depending on growing season, amount of irrigation, and fertilizer type, and their interactions.
