Solidago altissima, a perennial herb native to North America, has invaded and seen explosive growth in many parts of the world. However, the expansion has currently ceased in Japan, one of the severely invaded regions. We test the hypothesis that S. altissima is being outcompeted by Pueraria lobata, an expansive native species which has been spreading recently. By removing one of the two species growing together in a vegetation, their interspecific relationship was verified. After four months of regular clipping of P. lobata, the aboveground biomass of S. altissima increased significantly (2.8-fold) while that of other species remained unchanged. On the contrary, the removal of S. altissima did not change the biomass of P. lobata. This indicates that the growth of S. altissima was severely suppressed by P. lobata. We further found that the restrained growth of S. altissima was due to the reduction in the net assimilation rate, which was caused by P. lobata overshading the vegetation and preventing S. altissima from intercepting light. In the past, P. lobata was frequently utilized by humans as a source of food and medicine. As it is being harvested less these days, the constraints on its growth has reduced. The release of P. lobata from human pressure thus appears to be involved in the recent stagnation of S. altissima.","PeriodicalId":54302,"journal":{"name":"Botany Letters","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42848149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Progress in mathematics and computer science has allowed to incorporate an increasing number of parameters and to make models more and more realistic, often to the detriment of their analytical tractability. Here, we successively review the key aspects of forest plant community dynamics, and how they are accounted for by demographic and spatial models. Demographic models address the dynamics of a community at a local scale, and can be either continuous or discrete in time, purely deterministic or stochastic. Scaling up the dynamics of local communities to a landscape scale supposes to use spatial models, which can incorporate spatial heterogeneity and species dispersal. Aside spatially-implicit models, spatially explicit models treat space either as a continuous or a discrete variable, leading to different mathematical formalisms. Compared to statistical models, mechanistic models have a higher predictive power under changing environment (i.e. model extrapolation as opposed to model interpolation for which statistical models perform better) and are thus increasingly popular. However, as their complexity increases, their mathematical tractability decreases and mechanistic models are chiefly used for simulations. In this review, we analyse the pros and cons of the most widely used modelling frameworks in plant ecology and finally provide some perspectives.","PeriodicalId":54302,"journal":{"name":"Botany Letters","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42627029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High-elevation nunataks, that is bedrock islands protruding from glaciers with upper-most flowering plants, are no exception. Yet the consequences of climate change on nunatak vegetation remain relatively unexplored. Here, we report findings from a re-visit of historical plant surveys carried out on six nunataks situated between 2180 m a.s.l. and 3509 m a.s.l. amidst the glaciers of the Mont-Blanc range (France). We compared vegetation surveys conducted in 2020 to those made 150 years before, and performed remote sensing analyses to depict changes in vegetation productivity during recent decades. We report an increase in plant species richness for the lowest and least isolated nunataks, which contributed to a strong signal of vegetation greening over the last 35 years. This trend was due to the upward migration of competitive species, but also due to species colonization from neighboring high alpine areas into recently unglaciated microsites. We also highlight striking ecological trajectories that have been little discussed so far, such as stable vegetation composition in the highest and most isolated nunataks, an increase of plant species associated with non-permanent snow-cover and water run-off, an increase of graminoids at lower elevations, and of phanerophytes at higher elevations. We argue that high alpine vegetation changes are not driven by the sole upward migration of lowland competitive species, and that careful monitoring of ongoing ecological changes over broad elevation gradients is necessary to better understand the rapid transformation of high alpine landscapes.","PeriodicalId":54302,"journal":{"name":"Botany Letters","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46909581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
