Litter input is a critical link between the circulation and flows of energy matter in forest ecosystems. Drought events impact litter inputs, affecting ecosystems' nutrient cycles. To investigate response production to extreme drought, explore their recovery mechanism, difference whole year, concurrent non-drought period, rainy season, dry season. We studied an drought event subtropical evergreen broadleaved Ailao Mountain 2009–2010. used 10 years (2005–2014) monthly climate data, including average precipitation (MAP), soil water content (SWC), temperature (MAT). The observation period was separated into pre-drought (2005–2008), during-drought (2009–2010), post-drought (2011–2014) periods. found that annual total decreased by 12 % during (p < 0. 05), similar period.

Site elevation is a crucial driver for mangrove restoration, and litter production restoration significantly important target of but little attention has been paid to impact site on the elemental composition in restored forests. This study compared at three intertidal elevations, explore impacts litter. Compared with upper site, lower annual was found site. Leaf main component litter, up 60.49% total while reproductive materials (flower fruit) were key part accounted 50.80% (the site) 57.02% middle production. As decreased, element stocks within decreased by approximately 65.39% (organic carbon), 65.17% (total nitrogen) 63.66% phosphorus), respectively, which attributed more leaf instead other Results showed that decreases resulted production, altered percentages reduced In future projects, it advisable prioritize (above local mean level) promoting

We present a meta-analysis of mangrove litterfall across 58 sites in the American Pacific, exploring its variability among geoforms, ecoregions, and provinces. This study contributes to filling information gap on litter-based primary productivity mangroves at ecoregional level directly examines effects geomorphological biogeographic factors productivity. The objective was evaluate how geoform, ecoregion, province factors, along with eight environmental variables, influence litterfall-based Each site categorized according landform through analysis satellite images obtained from various sensors Google Earth Pro v. 7.3.6 platform. Additionally, it ecoregion by analyzing occurrence unit coverage ArcMap 10.4.1. then analyzed effect each factor efficiency categorization using multivariate methods. Our results showed significant differences estuaries exhibiting higher production (11.90 Mg ha−1 year−1) compared lagoons (7.49 ± 4.13 year−1). Differences were also observed provinces, highest average Tropical Eastern Pacific (11.19 3.63 lowest Warm Temperate Northeast (7.34 4.28 Allocation success analyses indicated that classified dominant species more predictable (>60.34%) for production. maximum temperature precipitation wettest month driest explained 34.13% conclude is influenced coastal geomorphic characteristics biogeography, which are, turn, affected latitude-induced climate variation.

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