However, the attributes that have made them successful in canopy environments also make them vulnerable to natural and human-induced disturbances. Drawing upon ecological frameworks to understand disturbance, I categorized and synthesized the drivers and the consequences of disturbances on epiphytic materials. Across all impacts, disturbance agents were significantly more likely to lead to negative, rather than positive, effects in both tropical and temperate locales. Significantly more studies reported negative effects on abundance, diversity, community composition and connectivity, but some studies showed that disturbances enhanced these attributes. Although particular disturbance agents did not differently influence individual consequences, they explained a significant portion of variation in aggregated totals. Surprisingly, relative to human disturbances, natural disturbances were more likely to lead to negative effects. Many studies provided recommendations for effective societal responses to mitigate negative impacts, such as retaining large, old trees in forestry operations, patch-clearing for epiphyte harvest, maximizing forest fragment size, using epiphytes as bioindicators of disturbance, and applying principles of community forestry to land management. Future actions should also include communication of these results to policymakers and land managers.</p>","PeriodicalId":48887,"journal":{"name":"New Phytologist","volume":"240 4","pages":"1366-1380"},"PeriodicalIF":9.4,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/nph.19245","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41216833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Redundancy between paralogous genes is an intriguing outcome of duplicate gene evolution, and its maintenance over evolutionary time has long been considered a paradox. Redundancy can also be dubbed ‘a geneticist's nightmare’: It hinders the predictability of genome editing outcomes and limits our ability to link genotypes to phenotypes. Genetic studies in yeast and plants have suggested that the ability of ancient redundant duplicates to compensate for dosage perturbations resulting from a loss of function depends on the reprogramming of gene expression, a phenomenon known as active compensation. Starting from considerations on the stoichiometric constraints that drive the evolutionary stability of redundancy, this review aims to provide insights into the mechanisms of active compensation between duplicates that could be targeted for breaking paralog dependencies – the next frontier in plant functional studies.</p>\u0000 </div>","PeriodicalId":48887,"journal":{"name":"New Phytologist","volume":"240 4","pages":"1381-1389"},"PeriodicalIF":9.4,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41148514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Iversen","doi":"10.1111/nph.19220","DOIUrl":"https://doi.org/10.1111/nph.19220","url":null,"abstract":"<p>Informed by vegetation maps across high-latitude landscapes, terrestrial biosphere models are a tool that can be used to predict changes in the composition and function of vegetation, above- and belowground, across the land surface in response to changing environmental conditions. However, terrestrial biosphere models represent vegetation characteristics at a finer grain than mapped vegetation communities. These models group plant species that colonize high-latitude biomes by their functional trait variation into plant functional types (PFTs) that characterize the impacts of plant species on, and their response to changes in, their surrounding abiotic and biotic environment. Blume-Werry <i>et al</i>. (<span>2023</span>) found that vegetation mapping units that broadly incorporate multiple plant species and functional types are too coarse, or encompass too much biological variation, to fully capture belowground plant trait variation. However, they did find that they could successfully cluster rooting depth observations into ‘Root Profile Types’, suggesting that modeling PFTs may be a useful tool to characterize above- and belowground linkages across high-latitude environments.</p><p>In many arctic and boreal ecosystems, plant roots are constrained by permafrost to a shallow ‘active layer’ of soil that thaws progressively over the course of each growing season. Blume-Werry <i>et al</i>. (<span>2023</span>) identified active layer thickness and the closely related minimum temperature of the coldest month as two of three main abiotic drivers constraining rooting depth distribution in their analysis (a third, cation exchange capacity, is more indicative of nutrient availability than a physical impediment). Furthermore, waterlogging can limit root distribution to surface, oxic soils, and can lead to a thick layer of poorly decomposed, organic peat at the soil surface with different characteristics from mineral soils (Fig. 1; Walker <i>et al</i>., <span>2003</span>). Indeed, Blume-Werry <i>et al</i>. (<span>2023</span>) found that despite similarities in species composition between wetland and graminoid tundra in CAVM mapping units, rooting depth in wetland tundra was shallower than graminoid tundra. This may indicate that waterlogged conditions can constrain rooting depth distribution, even in vegetation communities dominated by species with aerenchymatous roots. Ranging from rootless mosses and plant-like lichens to vascular graminoids and shrubs, and deciduous and evergreen trees, PFTs inhabiting the arctic tundra and boreal forest vary in their rooting depth distributions, their interactions with soil microbiota, and their ratio of belowground to aboveground tissues (e.g. root : shoot ratio; Chapin <i>et al</i>., <span>1996</span>).
