However, whether and how the responses of community temporal stability to land-use and nutrient enrichment change with time remain poorly understood. As part of a 15-yrs (2005–2019) field experiment, this study was conducted to explore the effects of mowing, nitrogen (N) and phosphorus (P) additions on community temporal stability in a temperate steppe on the Mongolian Plateau. Over the 15 years, N and P additions decreased community temporal stability by reducing the population stability, especially of the shrub and semi-shrub stability. However, mowing increased community temporal stability in the early stage (2005–2009) only. Nitrogen addition suppressed community temporal stability in the early and late (2015–2019) stages, whereas enhanced it in the intermediate stage (2010–2014). Phosphorus addition decreased community temporal stability marginally in the early stage and significantly in the late stage. The fluctuations of N-induced changes in community temporal stability are mainly explained by its diverse effects on species asynchrony and population stability over time. Our findings highlight the important role of plant functional groups and species asynchrony in regulating community temporal stability, suggesting that more long-term studies are needed to accurately forecast ecosystem response patterns in the context of global change.","PeriodicalId":50085,"journal":{"name":"Journal of Plant Ecology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49316555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a growth chamber experiment to compare the effect of water regime and temperature on growth and mortality of native and invasive populations of common gorse seedlings (Ulex europeaus, L). Seeds were sampled from 20 populations from five areas from both native (continental France and Spain) and non-native areas (New Zealand, Canary and Reunion islands). The seedlings were grown over 36 days in two temperature treatments (ambient and elevated) combined with two water treatments (irrigated or droughted). The elevated temperature was defined as the highest temperature observed at the niche margin in the different countries. While elevated temperature increased seedlings growth, the drought treatment increased mortality rate and limited seedlings growth. Under elevated temperature and drought, native populations showed a greater mortality rate (53%) than invasive populations (16%). Invasive seedlings also showed higher above- and belowground development than native ones under these constrained climatic conditions. While phenotypic plasticity did not differ between native and invasive populations, the difference between populations in terms of total dry mass could be related to differences in the climate of origin (precipitation in particular). Assessing the importance of phenotypic changes between populations within invasive species is crucial to identify the margins of their climatic distribution range and to highlight areas where management efforts should be concentrated in order to limit its spread.","PeriodicalId":50085,"journal":{"name":"Journal of Plant Ecology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44342156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given that pollinators often move across multiple plant species, the plant‒plant interactions that take place via heterospecific pollen (HP) transfer may also vary temporally, which could have important implications for floral evolution and community assembly. Here, we evaluated the interannual variation in plant–pollinator networks and plant‒plant heterospecific pollen transfer (HPT) networks of a subalpine meadow community in Southwest China for three consecutive years. The interactions largely varied between years for both network types. The composition of donor-species HP deposited on the plants varied less than did the visit composition of the pollinators, which suggested that HP could be transferred from identical donor species to recipient species through different shared pollinators between years. The plant species were at more similar positions in the HPT network than they were in the plant–pollinator network across years. Moreover, the more generalized plant species in the plant–pollinator network tended to export their pollen grains and more strongly influence HPT. We evaluated the relatively stable structure of the HPT network compared with the plant–pollinator network, which represents an important step in the integration of plant–pollinator and plant‒plant interactions.","PeriodicalId":50085,"journal":{"name":"Journal of Plant Ecology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2022-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41525148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been suggested that phosphorus is the main limiting nutrient in subtropical forests, and that evergreen and deciduous species adopt different carbon capture strategies to deal with this limitation. However, these hypotheses have not been examined empirically to a sufficient degree. In order to address this gap in our knowledge, we measured leaf photosynthetic and respiration rates, and nutrient traits related to phosphorus (P), nitrogen (N), and carbon (C) use efficiencies and resorption using 75 woody species (44 evergreen and 31 deciduous species) sampled in a subtropical forest. The photosynthetic N-use efficiency (PNUE), respiration rate per unit N and P (Rd,N and Rd,P, respectively) of the deciduous species were all significantly higher than those of evergreen species, but not in the case of photosynthetic P-use efficiency (PPUE).These results indicated that, for any given leaf P, evergreen species manifest higher carbon use efficiency (CUE) than deciduous species, a speculation that was empirically confirmed. In addition, no significant differences were observed between deciduous and evergreen species for nitrogen resorption efficiency (NRE), phosphorus resorption efficiency (PRE), or N:P ratios. The data indicate that evergreen species coexist with deciduous species and maintain dominance in P limited subtropical forests by maintaining CUE. The data also indicate that it is important to compare the PNUE of deciduous species with evergreen species in other biomes. These observations provide insights into modeling community dynamics in subtropical forests, particularly in light of future climate change.","PeriodicalId":50085,"journal":{"name":"Journal of Plant Ecology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49063658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We tested whether microorganisms in P-poor tropical forest soils increased the phosphomonoesterase (PME) to phosphodiesterase (PDE) activity ratio, because a one-step enzymatic reaction of monoester P degradation might be more adaptive for microbial P acquisition compared to a two-step reaction of diester P degradation. A continuous 10-year P addition experiment was performed in three tropical forests. The activities of PME and PDE, and their ratio in soil, were determined under the hypothesis that the P-fertilized plots—where P shortage is relieved—would have lower PME:PDE ratios than the unfertilized controls. We demonstrated that long-term P addition in tropical forest soil did not alter the PME:PDE ratio in primary and secondary forests, whereas P fertilization elevated the PME:PDE ratio in planted forest. These results were in contrast to previous results. The long-term, large-scale P fertilization in our study may have reduced litter- and/or throughfall-derived PDE, which negated the lowered PME:PDE ratio via exogenous P inputs.","PeriodicalId":50085,"journal":{"name":"Journal of Plant Ecology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41548968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plants of different diameter classes in a Larix olgensis near-mature forest (31 years old) in the hilly area of the Sanjiang Plain were used. The relationship between the time lag Js-Rs and tree characteristics, adjacent tree characteristics and slope positions was evaluated. Though both Js and Rs exhibit diurnal variation, they are not synchronized, thus leading to a time lag between Js and Rs. During the growing season, the change in Js lags behind the change in Rs by 21.1 ± 6.9 min. Compared with tree height and crown width, the time lag Js-Rs was more dependent on DBH. The time lag between Js and Rs showed a linear increase with DBH. Compared with the characteristics of neighboring trees, the time lag Js-Rs were more dependent on their own tree characteristics. A significant relationship is not observed between the time lag Js-Rs and SWC. The effects of tree characteristics, adjacent tree characteristics, and slope positions on the formation of the time lag Js-Rs were compared. The time lag of Js on Rs was mainly controlled by the tree characteristics (DBH).

At each site, grassland outside of the fencing experienced continuous grazing, whereas that within the fencing was protected. Results showed that grazing exclusion significantly increased aboveground biomass, species richness, and the Shannon–Wiener diversity index by 126.2%, 42.6%, and 18.8%, respectively. Grazing exclusion reduced the concentrations of nitrate and total inorganic N by 51.9% and 21.0%, respectively, suggesting that there may be a mismatch between N supply and plant demand during the growing season. The aboveground biomass, species richness, and Shannon–Wiener diversity index in the restored grasslands were positively correlated with legume dominance within the community.
