This paper gives a thorough account of the species’ systematic position and taxonomy, highlighting the difficulties to delimit taxa, which is related to interbreeding among members of this genus. However, <em>L. polyphyllus</em> var. <em>polyphyllus</em> is apparently the taxon that has naturalized and is regionally invasive in temperate-humid climates worldwide. We also present an updated distribution map of <em>L. polyphyllus</em> in the native and invaded ranges, which highlights seven regions in the world where the species has been established. We show that the climatic niche of <em>L. polyphyllus</em> in the invaded range shifts towards higher summer precipitation and lower isothermality, probably because the invaded range includes subcontinental regions of eastern Europe and western Siberia. The habitats of <em>L. polyphyllus</em> range from rather dry to wet, have moderately acidic to strongly acidic soils, and the species’ indicator values across Europe suggest that it occurs along a gradient from very nutrient poor sites to intermediate to rich sites from northern to southern Europe. The species shows high resistance to both drought and frost. In Central Europe, the species has a stronghold in alpic mountain hay meadows, abandoned meadows and pastures, low and medium altitude hay meadows, anthropogenic herb stands and temperate thickets and scrubs. In northern Europe, the species occurs in anthropogenic herb stands along roads and railroads as well as in abandoned pastures and fields. We also found some doubtful information about <em>L. polyphyllus</em> in the literature. This refers to its description as “rhizomatous perennial” although it lacks rhizomes; an apparently very high longevity of its seeds, which may only be true under artificial conditions in an ex situ seed repository; and a very deep rooting depth, which may not represent the average rooting depth but rather an extreme value. Knowledge about the interrelationships between the species’ future population dynamics and spread and ongoing climate warming is lacking. Finally, our review points out that there is currently no evidence-based strategy for a cost-efficient management of <em>L. polyphyllus</em> although it is among the most problematic non-native plant species in Europe due to its environmental and socio-economic impacts.</p></div>","PeriodicalId":56093,"journal":{"name":"Perspectives in Plant Ecology Evolution and Systematics","volume":"58 ","pages":"Article 125715"},"PeriodicalIF":3.6,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50192340","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}

ID is often found to increase under stress, but there are also reports of no effects or even a reduction of ID under stress. One reason for this variation that has received little attention may be related to different concepts of stress. In particular, the magnitude of ID may be unrelated to the effect of an environment on fitness (evolutionary stress concept), but increase particularly during the ‘alarm phase’ after a stress has been initiated (physiological stress concept). We clonally replicated inbred and outbred &lt;/span&gt;&lt;span&gt;&lt;em&gt;Mimulus guttatus&lt;/em&gt;&lt;/span&gt;&lt;span&gt;&lt;span&gt;&lt;span&gt; plants, for which ID was known to increase under flooding. We exposed the clonal replicates to control and flooding conditions and harvested replicates of each genotype after two, six and 11 weeks of growth. As functional traits related to stress response we measured &lt;/span&gt;chlorophyll fluorescence&lt;span&gt;, root mass and the production of stolons and &lt;/span&gt;&lt;/span&gt;adventitious roots. As fitness estimates we measured biomass and flower number, and we pollinated a subset of plants and grew a second generation of plants under control and flooding conditions to calculate multiplicative fitness. Overall, &lt;/span&gt;&lt;em&gt;M. guttatus&lt;/em&gt; proved to be very flooding-tolerant. Chlorophyll fluorescence (F&lt;sub&gt;v&lt;/sub&gt;/F&lt;sub&gt;m&lt;/sub&gt;) was not influenced by flooding, but decreased with leaf age and increased after fertilization.

Flooding reduced the root mass in the pots, but increased the production of stolons and floating roots. Plasticity in these traits can be regarded as beneficial, although selection gradient analysis&lt;span&gt; failed to identify plasticity in stolon number as adaptive. Only two functional traits were influenced by an interaction between flooding and inbreeding, early stolon length (suggesting a reduced flooding escape response of inbred plants) and root tissue density of floating adventitious roots (suggesting a reduced aeration of the roots of inbred offspring). ID in fitness-related traits was higher under flooding, but its magnitude changed strongly over the course of the experiment. ID under flooding was particularly high after two weeks (δ = 0.42 vs. 0.05 in the control), suggesting sensitivity of inbred plants to the initiation of flooding (‘alarm phase’ of stress response).

Generally, in study plots that received grass-triggering rainfall most recently, the roots of the dead grasses in FCs were in 100 % of the cases undamaged, root-shoot ratios were significantly greater, and the roots were as long or even longer as those of the surrounding matrix grasses outside of the FCs. This indicates that drought stress<span> caused grasses in the FCs to invest resources into roots to reach the percolating water<span><span>. The results also show that the cause of the grass death in fairy circles was not induced by termite herbivory. Also, we found no systematic differences in the rate of water infiltration between FCs and the matrix, hence the plant wilting cannot result from quicker percolation within FCs. However, the soil-moisture measurements indicate that the matrix grasses strongly depleted the upper </span>soil water of the FCs after rainfall, which explains why most grasses cannot establish and quickly die in the FCs. The research shows that grass death in fairy circles occurs immediately after rainfall due to plant water stress but not due to termite activity. Our results conform with previous fieldwork, pattern analysis and theoretical modeling, suggesting that Namibia’s fairy circles are a self-organized vegetation phenomenon induced by ecohydrological feedbacks.</span></span></span></p></div>","PeriodicalId":56093,"journal":{"name":"Perspectives in Plant Ecology Evolution and Systematics","volume":"57 ","pages":"Article 125698"},"PeriodicalIF":3.6,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48961273","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}

We studied whether predictor transformation affects the shape of the fitted curves. To test the effect of predictor transformation on the shape of the fitted curves, we re-analyzed the dataset of a highly-cited global analysis on the productivity–species richness relationship without performing any data transformations and contrasted the results with those of the original analyses that used log-transformed productivity data. We found that predictor variable transformation, which was used in the original paper, changed the shape of fitted curves in 32 % of the sites as well as the shape of the global relationship compared to the use of untransformed data. Therefore, we propose the reconsideration of predictor transformation and suggest an alternative approach: the piecewise regression. We found that piecewise regression is robust against predictor variable transformation. It resulted in much fewer inconsistent shape categories between the transformed and untransformed cases compared to the original analyses (2 instead of 9). We suggest that studies applying untransformed and transformed predictors when studying the shape of species richness curves along gradients are not directly comparable.

Lineages that accumulate these characteristics are known as “depauperons'' and explaining their existence and persistence through time is still a challenge. The plant family Melastomataceae<span> contains both megadiverse lineages (such as the tribe Miconieae, with around 1900 species) and groups with few species (such as the tribes Eriocnemeae, Lithobieae, and Rupestreeae with 7, 1 and 2 species, respectively). These three clades are restricted to eastern Brazil, where they have been seldom studied. The lack of information about their basic biology as well as which processes determine their distribution have not been previously studied. Here we integrated metrics of dispersal ability, species distribution models (SDMs) and natural history data compilation in order to uncover common patterns shared by these depauperons in Melastomataceae and raise conservation concerns. For all nine species we estimated the dispersal ability and generated SDMs in different time-periods (past, present and future). Dispersal ability was associated with predicted distribution models under future scenarios to evaluate shifts and/or retractions in suitable areas. In addition, we compared the climatic tolerances of the depauperons with their megadiverse sister tribes via climatic envelopes. Overall, our results indicate limited dispersal ability, dependency on water for dispersal, and restricted niche as common characteristics for all species in the deupauperon tribes Eriocnemeae, Lithobieae and Rupestreeae. Our analyses also show that the climatic niche spaces of the depauperons are limited and totally included within the niche space of its sister tribes.
