Abstract Clonal plants play key roles in maintaining community productivity and stability many ecosystems. Connected individuals (ramets) of clonal can translocate share, for example, photosynthates, water nutrients, such physiological integration may affect performance both heterogeneous homogeneous environments. However, we still lack a general understanding whether or how differs across versus We compiled data from 198 peer‐reviewed scientific studies conducted 19 countries with 108 plant species 35 families, carried out meta‐analysis effects on 16 traits related to growth, morphology, physiology allocation. Our analyses evaluated these relationships (A) environments where at least one resource essential growth (e.g. light, soil mineral nutrients) non‐resource factor grazing, trampling burial) is spatially non‐uniformly distributed (B) all factors are uniformly distributed.

Vertical variation in leaf functional traits of Parashorea chinensis with different canopy layers

Introduction Canopy species need to shift their ecological adaptation improve light and water resources utilization, the study of intraspecific variations in plant leaf functional traits based at individual scale is great significance for evaluating adaptability climate change. Methods In this study, we evaluate how giant trees relate spatial niche specialization along a vertical gradient. We sampled tropical flagship Parashorea chinensis around 60 meters tall divided crowns into three layers. Fourteen key including morphology, photosynthetic, hydraulic chemical physiology were measured each canopy layer investigate variation interrelationships between different traits. Additionally, due potential impact measurement methods ( in-situ ex-situ branch) on photosynthetic physiological parameters, also compared effects these two gas exchange measurements. Results discussion In-situ measurements revealed that most individual-to-individual P. varied significantly heights. Leaf such as midday (MWP) osmotic (OP) insignificantly correlated with maximal net assimilation rate per mass A ). addition, discrepancies found parameters. The caused decrease by 53.63%, 27.86%, 38.05% , 50.00%, 19.21%, 27.90% saturation point These findings provided insights our understanding response mechanisms micro-habitat Xishuangbanna seasonal rainforests fine adaption resultant decoupled traits, which have implications strategies under environmental changes.

Growth and Morphological Responses of Duckweed to Clonal Fragmentation, Nutrient Availability, and Population Density

Connected ramets of aquatic clonal plants are susceptible to fragmentation by disturbance. Such may interact with nutrient availability and individual density affect growth morphology plants. We grew the widespread floating plant Spirodela polyrhiza (duckweed) under three levels population (low, medium, or high), two (low (with without). Clonal high nutrients increased biomass ramet number, but decreased frond width, length, specific area S. polyrhiza. Increasing (biomass number) root size, thickness The negative effect on was greater than low availability. Furthermore, total mass without. These results suggest that fragmentation, can Competition for space, rather light, be mechanisms underlying reduced As increase production polyrhiza, disturbance potentially causes cannot recommended as a measure limit spread

Microclimatic variation in tropical canopies: A glimpse into the processes of community assembly in epiphytic bryophyte communities

Abstract Epiphytic communities offer an original framework to disentangle the contributions of environmental filters, biotic interactions and dispersal limitations community structure at fine spatial scales. We determine here whether variations in light, microclimatic conditions host tree size affect variation species composition phylogenetic epiphytic bryophyte communities, hence, assess contribution filtering, constraints competition assembly. A canopy crane giving access 1.1 ha tropical rainforest Yunnan (China) was employed record hourly light from 54 dataloggers 408 plots. Generalized Dissimilarity Modelling implemented analyse relationship between taxonomic turnover among host‐tree characteristics variation. Within‐tree vertical significantly about 30% higher than horizontal among‐trees. Thus, sharp base are more important differences age, reflecting likelihood colonization, area, habitat young old trees, shaping communities. Our models, which factors contributed most (83–98%), accounted for 33% 18% mosses liverworts, respectively. Phylogenetic shifted negative or non‐significant within positive slightly, but significantly, correlated with These patterns highlight crucial role microclimates determining Synthesis.

Effects of clonal integration, nutrients and cadmium on growth of the aquatic macrophytePistia stratiotes

Journal of Plant Ecology, Год журнала: 2020, Номер 13(6), С. 765 - 772

Опубликована: Окт. 2, 2020

Abstract Aims Many wetlands are polluted with both nutrients and toxic metals vegetated largely by clonal plants. We hypothesized that eutrophication integration can increase phytoremediation of metal pollution increasing plant growth, even under the stress imposed toxicity. Methods To test this hypothesis, single ramets common, widespread, floating, stoloniferous Pistia stratiotes L., were grown for 42 days at two levels nutrient availability without 0.6 mg L−1 cadmium. Ramets either severed from their vegetative offspring to prevent or left connected, removed eliminate intraclonal competition in place. Important Findings Plants subjected cadmium addition accumulated almost twice as much dry mass if given higher level, due mainly a doubling number offspring. Severance had little effect on final parent plus ramets. Removing following severance no parental ramet presence added cadmium, but it did absence These results support hypothesis remediation aquatic macrophytes provided evidence affect remediation. Species such P. may help remediate co-pollution nutrients, fragmentation clones not capacity.

Abstract Carbon (C) allocation among different plant tissues is crucial for maintaining C balance in forest ecosystems, especially under changing climate conditions. The partitioning of newly assimilated tissues, interconnected ramets and soil forests dominated by giant clonal plants, such as moso bamboo ( Phyllostachys edulis ), the influence drought on this remain poorly understood. In August 2019, we performed situ labelling entire crown R0 (ramets that emerged 2019) with 13 CO 2 plots subjected to a 5‐year or left untreated (ambient control) subtropical China. We then traced signatures leaves, twigs fine roots R0, R1 2018 are connected R0) R2 2017 R1), well organic (SOC) respiration over course 1‐year post‐labelling. Drought reduced leaf assimilation its sink but did not alter velocity transport from source compared controls. peak signal was observed day 15 SOC 5 respired both ambient control forests.

Synthesis . large bamboo, can may affect plant–soil systems. Our findings highlight complexity these suggest integration mitigate drought‐induced dieback older through resource sharing change.
