We supplemented the existing fragmentary genetic and morphological data mainly from North America and South Asia with our data from East Europe and North Asia. We combined molecular barcoding of the nuclear phyC<span> and plastid psbJ-petA DNA regions (382 samples) with morphological analysis of herbarium collections (more than 1500 specimens from 16 herbaria) and numerous natural populations with a special focus on hardly accessible Siberian and the Far Eastern regions of Russia. We found that aquatic </span></span><em>Sparganium</em> is represented in North Eurasia by nine species and 14 hybrids. Nine previously unknown hybrids are formally described as new nothotaxa. All species and hybrids could be reliably discriminated with barcoding. We refined the distribution of all taxa in North Eurasia, e.g., <em>S</em>. <em>angustifolium</em>, a species avoiding continental areas, where it was confused by many authors with mostly vegetative specimens of other taxa. In the <em>S</em>. <em>emersum</em> complex in addition to recognized earlier widespread <em>S</em>. <em>emersum</em> and eastern North American <em>S</em>. <em>chlorocarpum</em> we proved the existence of one more distinct lineage – Asian Pacific <em>S</em>. <em>rothertii</em>. We discovered different evolutionary lineages within some species (e.g., <em>S</em>. <em>glomeratum</em> and <em>S. hyperboreum</em><span>) causing additional issues in the taxa identification. Almost all species cross with each other, usually acting both as plastid and pollen donors. Most of the hybrids are widespread and abundant. They originate each time when the ranges of parental species overlap and suitable habitats are available, and rather do not disperse from the centres of origin. Hybridization can be a threat to species with narrow ecological tolerance. Active gene flow is also evident within species when different evolutionary lineages come in contact (e.g., </span><em>S</em>. <em>emersum</em>, <em>S. rothertii</em>, <em>S</em>. <em>glomeratum</em>, <em>S. hyperboreum</em>, <em>S. natans</em>).

The origin of these “fairy circles” (FC) is subject of an ongoing debate. In a recent article in PPEES, Getzin et al. (2022) provided assessments of grasses and termites combined with soil moisture measurements, in and near to fairy circles in several areas in Namibia. In their interpretation they state that termite herbivory is not causing this grass death as the plants had undamaged roots. Instead they propose that the matrix grasses severely depleted the water in FCs. Here, we use a comprehensive, detailed body of measurements and assessments collated during the last 14 years to propose an alternative interpretation. We structure our interpretation with four statements, each of them based on shown evidence: (1) Long-term soil moisture measurements confirm that the soil beneath the dry topsoil of the bare patch of fairy circles contains an equal or, especially during the biologically active season, higher amount of moisture than the surrounding matrix, at any given time. The grasses of the fairy circles bare patch die during the moist phase of the first weeks after a rain, before even the soil beneath the matrix vegetation gets depleted by transpiration. (2) Within the sandy soils of fairy circle landscapes, there is no sufficiently strong “uptake –diffusion feedback” that could cause a horizontal movement of soil moisture over several meters within a few days. (3) The grasses of the fairy circles bare patch first die at the centre of the bare patch and later towards the margin. (4) The grass in the bare patch of fairy circles dies because of damage to roots due to herbivory by sand termites.</p></div>","PeriodicalId":56093,"journal":{"name":"Perspectives in Plant Ecology Evolution and Systematics","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50189029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

As a result, range limits may shift as dispersal barriers are removed, climates change, and local species composition is altered, but the relative importance of these mechanisms is still not well understood. This is particularly true for introduced species, where current range limits may or may not reflect range limits at equilibrium, and is becoming more pressing under the effects of global climate change. To understand the drivers and stability of range limits in introduced <span><em>Rumex</em><em> conglomeratus</em></span><span>, we used common garden experiments growing plants within, at the edge of and beyond their current range edge. Seeds were sourced from both lowland<span> and upland populations and planted at all three sites. By measuring survival, growth, and the occurrence of reproduction, we tested whether upland populations are locally adapted to high elevation sites and whether plants were capable of surviving and reproducing above the current range edge. However, we found that upland populations were not better adapted to higher elevations, and often were small and performed more poorly than lowland populations across sites. Upland populations appear to be maintained by human-aided seed dispersal from lowland populations, which may constrain the opportunity for local adaptation. Although some plants survived above the current range edge, frost and growing season length restricted plant size and reproduction was infrequent. Therefore, the current range limit seems unlikely to expand as long as regular frost continues at the range edge and dispersal from the lowland continues to prevent local adaptation to upland environments.</span></span></p></div>","PeriodicalId":56093,"journal":{"name":"Perspectives in Plant Ecology Evolution and Systematics","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2023-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46361580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Based on a large dataset of 18,000 tree individuals from 133 common species, distributed among twelve 1-ha plots (habitats) in the Atlantic Forest (Brazil), we evaluated how trait interactions and the environmental context influence the demographic rates (growth, mortality, and recruitment). Functional traits, trait-trait, and trait-habitat interactions predicted demography with a good fit through either BRTs or linear mixed-models. Changes in growth rates were best related to size (diameter), and mortality rates to habitats, while changes in recruitment rates were best related to the specific leaf area. Moreover, the influence of traits differed among time intervals, and for demographic parameters, habitat affected growth and mortality by interacting with diameter. Here, we provide evidence that trait-demography relationships can be improved when considering the environmental context (space and time) and trait interactions to cope with the complexity of changes in the demography of tropical tree communities. Thus, to expand predictions of demography based on functional traits, we show that it is useful to fully incorporate the concept of multiple trait-fitness optima, resulting from trait interactions in different habitats and growth conditions.</p></div>","PeriodicalId":56093,"journal":{"name":"Perspectives in Plant Ecology Evolution and Systematics","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42529708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}
