Russo","doi":"10.1002/ecm.70057","DOIUrl":"10.1002/ecm.70057","url":null,"abstract":"<p>The acquisitive–conservative spectrum of plant strategies is a well-supported interspecific trade-off axis: Compared to acquisitive species that prioritize resource allocation to functions promoting carbon fixation, conservative species tend to grow slower because a larger amount of resources is allocated to functions promoting survival. However, mycorrhizal allocation—potentially beneficial or costly to the plant—has not been fully integrated into this framework. We developed a model predicting plant growth along a soil fertility gradient, incorporating mycorrhizal allocation. Plant strategies are defined using the acquisitive–conservative spectrum, while mycorrhizal fungal strategies are defined based on how beneficial fungi are to plants and their sensitivity to soil fertility. Our results predict that conservative species exhibit greater mycorrhizal allocation under optimality than acquisitive species when paired with similar fungi in the same environment. This allocation difference across plant strategies becomes more prominent for plant associations with ectomycorrhizal versus arbuscular mycorrhizal fungi. Mycorrhizal allocation improves conservative species' growth across broader ranges of fungal strategies and soil fertilities, even to the point that they can achieve growth rates comparable to or exceeding those of acquisitive species in infertile soils when acquisitive species' mycorrhizal interactions (fungal strategy or allocation) are suboptimal. Our findings highlight broader ecological and evolutionary implications of trade-offs in mycorrhizal allocation for plant resource allocation. Ecologically, variation in mycorrhizal costs and benefits along the acquisitive–conservative spectrum can affect plant coexistence. Evolutionarily, greater opportunities to benefit from mycorrhizae may select for more optimized plant–mycorrhizal relationships, especially for conservative species.</p>","PeriodicalId":11505,"journal":{"name":"Ecological Monographs","volume":"96 1","pages":""},"PeriodicalIF":7.5,"publicationDate":"2026-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://esajournals.onlinelibrary.wiley.com/doi/epdf/10.1002/ecm.70057","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147492482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Arctic is the fastest-warming ecosystem on Earth and has already reached temperature increases not expected in the rest of the world until the end of the century. Consequently, synthesizing patterns of evolutionary and genetic change in Arctic species will be instructive for understanding future change in other systems. Here, we present a literature review of peer-reviewed published research exploring evolutionary processes in polar bears, a sentinel species for climate action. The wealth of knowledge generated from the long-term monitoring of polar bears has provided data for exploring patterns of evolutionary change associated with climate change. Warming temperatures have led to significant reductions in sea ice coverage and availability, contributing to declines in genetic variation in some, but not all, polar bear subpopulations. Natural selection driven by warming and selective subsistence harvests may be contributing to the evolution of smaller body sizes in polar bears. However, evidence of adaptive change in polar bears remains limited, despite clear behavioral and phenological plasticity in the species in response to changing sea ice conditions. Following our review, we suggest pathways for identifying the effects of climate warming on the evolution and genetic variation in polar bears, which may improve strategies for locally supported conservation and management decisions. Our results highlight the general complexity of predicting the consequences of warming for wide-ranging, genetically structured, and adaptively specialized species such as polar bears, and underscore the importance of developing evolutionarily informed management and conservation priorities for species threatened by climate change.</p>","PeriodicalId":11505,"journal":{"name":"Ecological Monographs","volume":"96 1","pages":""},"PeriodicalIF":7.5,"publicationDate":"2026-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://esajournals.onlinelibrary.wiley.com/doi/epdf/10.1002/ecm.70053","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147471028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the pronounced seasonality of alpine environments, we sampled eight plant species occurring in two habitats (alpine meadow and subnival zone) across four seasons (including the snow-covered winter) in the Central Eastern Alps to determine the plant growth strategies and plant nutrient parameters which closely couple with rhizosphere microbial parameters. In subnival locations, plants exhibited stronger seasonal changes among leaf and root tissue nutrient concentrations and non-structural carbohydrates (NSCs) compared to those in lower elevation alpine meadows. However, rhizosphere microbial parameters (microbial biomass carbon (MBC), extracellular enzymes, and community composition) demonstrated more seasonal changes in the alpine meadow locations. Notably, a phenological delay was observed in bacterial and fungal communities of the subnival zone, with peak plant rhizosphere differentiation occurring later in the season than in alpine meadows. Therefore, the prolonged cold conditions and shorter growing season in higher elevations likely add a temporal aspect to the commonly used elevational gradient approach, which is not often considered. MBC and enzymatic potential within the rhizosphere were high across all plant species in the alpine meadow during the winter sampling, despite notable differences in microbial community composition. In contrast, winter rhizosphere communities did not differ between plant species in subnival locations, although one species, <i>Oxyria digyna</i>, demonstrated much higher microbial activity along with higher NSCs and root nitrogen, suggesting some alpine plant species may acquire nutrients through microbial interactions during snow-covered winter periods. This study provides the first look at the annual phenology of multiple alpine plant species and their associated rhizosphere microbiome. Our results demonstrate that seasonal microbial dynamics are highly influenced by abiotic factors (soil and microclimatic conditions), but plants are able to modulate these conditions through growth and nutrient acquisition strategies. Taken together, seasonality and independent plant species effects cannot be overlooked when assessing habitat nutrient cycling and ecosystem stability.</p>","PeriodicalId":11505,"journal":{"name":"Ecological Monographs","volume":"96 1","pages":""},"PeriodicalIF":7.5,"publicationDate":"2026-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://esajournals.onlinelibrary.wiley.com/doi/epdf/10.1002/ecm.70055","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147439891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both these phenomena subject populations to novel conditions, either in space (species introductions) or in time (climate change), yet the role of adaptation in how populations respond to these rapid environmental shifts is poorly understood. We conducted a large-scale transcontinental common garden experiment using white clover (<i>Trifolium repens</i>, Fabaceae) to test whether adaptive evolution to spatiotemporal variation in climate could contribute to the ecological success of one of the most widespread plant species in the world. Individuals from 96 populations of <i>Trifolium repens</i> (white clover) from both its native (Europe) and introduced (North America) ranges were planted into four experimental common gardens located in northern (Uppsala, Sweden) and southern (Montpellier, France) Europe, and northern (Mississauga, Canada) and southern (Lafayette, USA) North America. We recorded plant sexual and clonal fitness in each common garden, and assessed whether the strength of local adaptation differed between the native and introduced ranges, and whether populations are rapidly adapting to climate change. Results show that local adaptation was only evident when populations were transplanted into common gardens located in the same range (native or introduced) from which they originated, and was driven by stronger selection (due to climatic factors rather than herbivory) at lower latitudes in both ranges. Our results indicate rapid local adaptation across a large latitudinal gradient in introduced <i>T. repens</i> populations, along with an associated adaptation cost when transplanted back into the native range. We also find evidence of an adaptation lag in the northern common garden in the introduced range, with plants from historically warmer climates exhibiting the greatest fitness. These findings support two major conclusions: (1) white clover can rapidly adapt to spatial variation in climate in its introduced range as well as its native range, and (2) despite rapid adaptation to novel environments, introduced white clover populations are not keeping pace with rapid climate change. Overall, our results provide insight into the role of adaptation in facilitating the ecological success of non-native species in a rapidly changing world.</p>","PeriodicalId":11505,"journal":{"name":"Ecological Monographs","volume":"96 1","pages":""},"PeriodicalIF":7.5,"publicationDate":"2026-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://esajournals.onlinelibrary.wiley.com/doi/epdf/10.1002/ecm.70043","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146198823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While metabolic scaling theory (MST) provides a valuable conceptual framework, it remains limited in its ability to fully explain community-level growth or carbon dynamics. To address this limitation, we developed an iterative growth model for forests (IGMF), built upon an iterative growth framework grounded in MST's core principles and further incorporating the self-thinning effect. The IGMF and its extensions suggest that community-level growth, net primary productivity (NPP), and other key components of the carbon budget—including gross primary productivity, autotrophic respiration, organ turnover, and non-structural carbohydrate storage—may be approximated as functions of current biomass, biomass-specific maintenance respiration, stand age, or <i>M</i>_max. These relationships provide a basis for estimating the global <i>M</i>_max of WPCs during 2018–2020 at approximately 1440 ± 26 Pg (1 Pg = 1 × 10¹⁵ g), with an additional biomass potential of about 510 Pg under current conditions. However, machine learning projections suggest that this potential may decline by up to 246 Pg by 2100, primarily within evergreen broadleaf forests. Our analyses also indicate that species richness, by promoting functional convergence, can amplify the negative effects of temperature and precipitation seasonality on <i>M</i>_max. In contrast, warming in the Northern Hemisphere may favor <i>M</i>_max accumulation in open shrublands. Together, these results help to clarify the growth dynamics of WPCs and suggest a possible shift in the major contributors to terrestrial carbon sequestration—from forests to shrublands—under future climate scenarios.</p>","PeriodicalId":11505,"journal":{"name":"Ecological Monographs","volume":"96 1","pages":""},"PeriodicalIF":7.5,"publicationDate":"2026-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146122001","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}
