Lambrinos, Takenori Takada","doi":"10.1111/1365-2745.70049","DOIUrl":"https://doi.org/10.1111/1365-2745.70049","url":null,"abstract":"<h2>1 INTRODUCTION</h2>\u0000<p>Hinrichsen (<span>2025</span>) identifies two primary limitations of the interstage flow matrix introduced by Yokomizo et al. (<span>2024</span>). The first limitation is described as biological unrealism due to equal weighting for each individual across all the stages. According to Hinrichsen (<span>2025</span>), Yokomizo et al. (<span>2024</span>) assign the same weight to seeds and reproducing adults, which he argues is biologically unrealistic because it undervalues the differing contributions of life stages to population growth. Abundant stages, such as seed banks, disproportionately influence the entries in the interstage flow matrix.</p>\u0000<p>The second limitation is that interstage flow is scale-variant: Simply rescaling the stages alters its entries. Hinrichsen (<span>2025</span>) asserts that this limits the utility of the matrix for robust comparative analyses, as results can vary with changes in scaling.</p>\u0000<p>However, we assert that these two points are not shortcomings of the interstage flow approach but valuable features of it.</p>\u0000<h3>1.1 Limitation 1: Equal weighting among developmental stages</h3>\u0000<p>Hinrichsen (<span>2025</span>) claims that ‘seeds receive the same weight or ‘value’ as reproducing adults’ in the interstage flow matrix and proposes reweighting (rescaling) approaches to obtain scale-invariant forms of the interstage flow matrix. However, it is not biologically unreasonable for seeds and reproducing individuals to have equal weight, as population growth rate is fundamentally based on individual-level rates of increase.</p>\u0000<p>Life-history strategies vary among species. Some species produce many offspring with low survivorship, while others produce fewer offspring with higher survivorship (Pearl, <span>1928</span>). The imbalance that Hinrichsen critiques—such as the concentration of populations in immature stages—often reflects biologically meaningful traits rather than a problem requiring correction. Yokomizo et al. (<span>2024</span>) demonstrated that four functional groups (semelparous herbs, iteroparous herbs, shrubs and trees) exhibit distinct patterns of interstage flow allocation across stasis, fecundity and growth. Semelparous herbs are characterized by flows dominated by growth and fecundity, while trees emphasize stability with flows primarily dominated by stasis. Iteroparous herbs and shrubs display intermediate patterns, balancing flows across stasis, growth and fecundity. These differences align with life-history strategies and ecological adaptations.</p>\u0000<p>While balancing, as proposed by Hinrichsen (<span>2024</span>, <span>2025</span>), could be applicable to examine species characteristics, it is unclear how the balanced results should be interpreted. How meaningful is balancing that amplifies very small stages for understanding species traits? Balancing could also overly emphasize older individuals which represent a small proportion and contribute less to fecundity.

Indeed, there is a wide range of polymorphic sexual systems: gynodioecious (hermaphrodite and female), subdioecious (male, hermaphrodite and female) or dioecious (male and female), and these can form a continuum with intraspecific variation among populations within species (e.g. Costich &amp; Meagher, &lt;span&gt;2001&lt;/span&gt;; Dorken &amp; Barrett, &lt;span&gt;2003&lt;/span&gt;). Because the male and female reproductive pathways have different resource/mating demands, environmental variation can drive geographic patterns of sexual systems (reviewed in Varga &amp; Soulsbury, &lt;span&gt;2020&lt;/span&gt;). Recent concerns over anthropogenic change in climate factors and soil fertility (IPCC, &lt;span&gt;2022&lt;/span&gt;; Penuelas et al., &lt;span&gt;2013&lt;/span&gt;; Singh et al., &lt;span&gt;2020&lt;/span&gt;) have led ecologists to call for a broader understanding of the abiotic drivers of the key features of sexually polymorphic populations, such as sex ratio, sexual dimorphism and sex determination (Hangartner et al., &lt;span&gt;2022&lt;/span&gt;; Hultine et al., &lt;span&gt;2016&lt;/span&gt;; Varga &amp; Soulsbury, &lt;span&gt;2020&lt;/span&gt;). Yet, for most sexually polymorphic species the geographic relationship between-sex ratio and environment remains unexamined (Varga &amp; Soulsbury, &lt;span&gt;2020&lt;/span&gt;) and evidence of clinal variation in sexual dimorphism or sex-determining factors is all but absent in plants (but see Bürli et al., &lt;span&gt;2022&lt;/span&gt;; Puixeu et al., &lt;span&gt;2019&lt;/span&gt;)—especially at the range-wide scale.&lt;/p&gt;\u0000&lt;p&gt;In sexually polymorphic plant populations, the sex ratio is determined by the reproductive fertility of each sex morph, the genetic mechanism of sex determination, and the degree of sex environmental lability (reviewed in Käfer et al., &lt;span&gt;2022&lt;/span&gt;; Schenkel et al., &lt;span&gt;2023&lt;/span&gt;; Spigler &amp; Ashman, &lt;span&gt;2011&lt;/span&gt;). Given the lower energetic costs (Ashman, &lt;span&gt;1994&lt;/span&gt;; Obeso, &lt;span&gt;2002&lt;/span&gt;) of reproducing solely as a male (e.g. pollen production) than a female (e.g. ovule and seed production) in insect-pollinated plants, sex ratios can vary across gradients of environmental stressors (reviewed in Spigler &amp; Ashman, &lt;span&gt;2011&lt;/span&gt;; Varga &amp; Soulsbury, &lt;span&gt;2020&lt;/span&gt;). For instance, in gynodioecious species where hermaphrodites produce both pollen and as many seeds as females, they bear a higher reproductive cost than females. Female frequency is thus predicted to increase with increasing environmental stresses in gynodioecious species. For example, a survey of Illinois populations of &lt;i&gt;Lobelia spicata&lt;/i&gt; demonstrated female frequency increased with increasing temperature stress (Ruffatto ","PeriodicalId":191,"journal":{"name":"Journal of Ecology","volume":"17 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143880760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Furthermore, theoretical and empirical work shows that nutrient-induced losses in plant diversity may be mitigated when herbivores increase light at ground level (Borer, Seabloom, et al., &lt;span&gt;2014&lt;/span&gt;; Olff &amp; Ritchie, &lt;span&gt;1998&lt;/span&gt;). Experimental tests of drivers of plant diversity in terrestrial systems typically focus on vascular plants (VP), while non-vascular plants (NVP; here bryophytes), are usually ignored, even though NVPs can commonly represent 20%–40% of total plant diversity in grassland communities (Dengler et al., &lt;span&gt;2020&lt;/span&gt;; Klaus &amp; Müller, &lt;span&gt;2014&lt;/span&gt;; Löbel et al., &lt;span&gt;2006&lt;/span&gt;; Lyons et al., &lt;span&gt;2022&lt;/span&gt;; Tansley &amp; Adamson, &lt;span&gt;1925&lt;/span&gt;). It is therefore not known whether the response of NVP diversity to nutrient addition or grazing is consistent with that of VPs, in which case VP responses could predict NVP responses. However, NVPs could react differently (e.g. decrease to a greater or lesser degree), in which case their inclusion would refine our understanding of plant diversity loss in terrestrial systems.&lt;/p&gt;\u0000&lt;p&gt;In grassland ecosystems, NVPs consist mainly of two clades of land plants (Bryophyta (mosses) and Marchantiophyta (liverworts)) that contribute to many ecosystem functions and properties. Bryophytes often make up a large proportion of above-ground biomass (Boch et al., &lt;span&gt;2018&lt;/span&gt;; Hejcman et al., &lt;span&gt;2010&lt;/span&gt;; Wielgolaski, &lt;span&gt;1972&lt;/span&gt;), regulate the microclimate (Jaroszynska et al., &lt;span&gt;2023&lt;/span&gt;), hydrology (Michel et al., &lt;span&gt;2013&lt;/span&gt;), carbon and nutrient cycling (O'Neill, &lt;span&gt;2000&lt;/span&gt;; Turetsky, &lt;span&gt;2003&lt;/span&gt;), nitrogen fixation (Lindo et al., &lt;span&gt;2013&lt;/span&gt;), and affect seed germination of native and exotic vascular plants (Dollery et al., &lt;span&gt;2022&lt;/span&gt;), soil micro-organism diversity (Xiao et al., &lt;span&gt;2023&lt;/span&gt;) and soil multifunctionality (Xiao et al., &lt;span&gt;2024&lt;/span&gt;). Therefore, the presence and diversity of NVPs in terrestrial systems can have far-reaching ecological repercussions even in VP-dominated ecosystems. Important differences between NVPs and VPs, which may affect their ecological role, include that NVPs are an order-of-magnitude shorter than VPs, lack efficient conducting tissues, roots and stomata, and have relatively low photosynthetic rates (Rydin, &lt;span&gt;2009&lt;/span&gt;). Their small stature makes NVPs poor competitors for light, for which reason NVPs likely experience higher species loss rates than VPs, when increased nutrient supply intensifies competition for light (Rydin, &lt;span&gt;2009&lt;/span&gt;).&lt;/p&gt;\u0000&lt;p&gt;A handful of empirical studies over the past few decades","PeriodicalId":191,"journal":{"name":"Journal of Ecology","volume":"265 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143846650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
