Whereas it is well established for lowland species that plants of small populations have lower individual fitness, alpine species have not been sufficiently studied in this respect. It is also not clear whether relationships between population size and fitness vary between naturally rare and common species. We assessed how population size and rarity affect seed set, seed mass, seed number, total seed mass per fruit, germination, time to germination, offspring survival and offspring size in four congeneric alpine plant species pairs (<i>Androsace chamaejasme</i> Wulfen, <i>A. puberula</i> Jord. &amp; Fourr., <i>Primulaceae</i>; <i>Gentiana acaulis</i> L., <i>G. alpina</i> Vill., <i>Gentianaceae</i>; <i>Potentilla crantzii</i> (Crantz) Fritsch, <i>P. nivea</i> L., <i>Rosaceae</i>; <i>Viola calcarata</i> L., <i>V. lutea</i> Huds., <i>Violaceae</i>). Across all eight species, plants from smaller populations produced fewer seeds and had lower total seed mass per fruit than plants from larger populations. This demonstrates that population size also affects fitness in alpine species. Rare species did not have lower individual fitness than common species. Therefore, naturally rare species might be well adapted to their environment. Relationships between population size and fitness were equally pronounced in rare and common species. We conclude that plant fitness is reduced in small populations in alpine species, also in common species.</p></div>","PeriodicalId":51238,"journal":{"name":"Alpine Botany","volume":"135 1","pages":"7 - 18"},"PeriodicalIF":2.6,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00035-025-00328-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144074123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we employ satellite image analysis to investigate how the seasonal growth patterns in the mountain rangeland ecosystem respond to inter-annual variations in weather conditions along the elevation profile. Our analysis covers nine key habitats in mountain rangelands surrounding the Swiss National Park, southeastern Swiss Alps from 2000 to 2800 m of elevation. Using the Normalized Difference Vegetation Index (NDVI) to track the growth pattern from 2016 to 2023 reveals that inter-annual weather fluctuations affect all habitats, leading to variations of 15–20% in the growth curve, with more significant impacts observed in the first half of the growing season. When comparing growth among habitats, wet and mesic pastures tend to exhibit greater growth compared to dry habitats within the elevation range of 2000–2400 m above sea level, while all habitats show a similar growth above 2400 m. Additionally, the presented statistical analysis at the landscape scale supports the existence of growth dynamics previously observed at the plot scale: that snow persistence influences the beginning of growth in pastures, but this effect is partially compensated by rapid growth following late snow melt. Conversely, in the second half of the season, growth is controlled by the onset of snow in autumn. These results demonstrate the potential of the joint application of earth observation and spatial statistics, not only to monitor the regional response to climate trends and variability, but also to differentiate inter-annual and inter-habitat responses of growth dynamics.</p>","PeriodicalId":51238,"journal":{"name":"Alpine Botany","volume":"135 1","pages":"33 - 50"},"PeriodicalIF":2.6,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00035-025-00327-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144073982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plant height, stem height, total and photosynthetically-active rosette diameter and height to the base of the rosette were measured, to illustrate how the developmental stages compare. Five plant developmental stages were identified in the study: juvenile, subadult, adult, reproductive adult, and senescent reproductive adult.

Comparing locations, <i>Puya</i> plants in Queshque were smaller than in the other locations, across all developmental stages. This study provides an efficient and informative classification system for <i>P. raimondii</i> giant rosettes, using well-defined developmental stages, that can reveal important differences between populations and prompt the generation of new hypotheses about the ecology of these important plants.

Previous studies on the trait-based approach have attempted to explain plant performance using either aboveground or belowground traits at either the organ level or the whole-plant level. To understand the species-specific responses to climate change, however, it is crucial to examine various traits simultaneously and comprehensively, including both organ level and whole-plant-level traits of aboveground and belowground parts, within the same study. Changes in the abundance of plant species have been recorded in an alpine meadow of the Taisetsu Mountains, northern Japan, over a 40-year period. Based on the previous studies, we selected 4 species with decreasing trends and 8 species with increasing trend. Then, we compared 26 functional traits between the decreasing and increasing species to understand the underlying mechanisms that drove the different changes in abundance. Compared to the decreasing species, the increasing species had larger rhizomes and longer and thinner fine roots, suggesting that drought tolerance may be a key factor in understanding the differences in the abundance of alpine meadow plants. Our study demonstrated that belowground traits at the whole-plant level, as well as at the organ level, played essential roles in species-specific abundance changes in alpine meadow plants. This means that belowground traits are a crucial component predicting the changes in species diversity of alpine vegetation under global warming.</p></div>","PeriodicalId":51238,"journal":{"name":"Alpine Botany","volume":"135 1","pages":"65 - 78"},"PeriodicalIF":2.6,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144073938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These interactions range from specialized (involving few species) to generalized (involving many species), with the former being more vulnerable to disturbances because the loss of one member can lead to the disappearance of its mutualist. Thus, understanding the relationships of plant-pollinator interaction networks provide information about ecosystem resilience. It has been hypothesized that the tropics will have specialist pollination systems because of their higher diversity. However, little is known about pollination systems in the tropics, especially at high altitudes. We examined the plant-pollinator network within a Colombian páramo—an alpine tropical ecosystem—through a phytocentric sampling strategy spanning 22 months, including 305 h of direct observation and 3689 h of camera trapping, focusing on 36 common plant species. A total of 90 pollinator morphospecies were documented, including hummingbirds, bats, hymenopterans, dipterans, lepidopterans, coleopterans, and hemipterans. The network was modular (8 modules) and moderately specialized (H2′ = 0.45), yet with many generalist species (pollinator d′ = 0.36; plant d′ = 0.43), but low connectivity (0.10) and low nestedness (9.2). Modularity analysis identified 19 morphospecies pivotal to the network`s integrity including <i>Bombus rubicundus</i> as a network hub. Comparisons with Venezuelan and Costa Rican páramos suggest that the Colombian páramo's higher pollinator diversity may confer greater stability, though the potential loss of any of the hub and connector species could have cascading effects on extinction processes, making their conservation a priority.</p></div>","PeriodicalId":51238,"journal":{"name":"Alpine Botany","volume":"135 1","pages":"91 - 105"},"PeriodicalIF":2.6,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144073749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The formation of persistent soil seed banks is recognised as a critical component of a plant community’s resilience to a changing environment. However, our understanding of the ecology of snowpatch soil seed banks and their potential role in the persistence of these threatened communities remains limited. To address this knowledge gap, we (1) characterised the density, diversity and composition of snowpatch soil seed banks along a snowmelt gradient (with early, mid, and late melt zones defined); and (2) contrasted their similarity with long-term vegetation surveys (2020, 2013, 2007) to assess the relationship between soil seed banks and standing vegetation over time. We found persistent soil seed banks in all snowmelt zones and that the snowmelt gradient significantly influenced their density, diversity and composition. Species density and diversity in soil seed banks were higher in the early and mid zones compared to the late zone. However, seedlings from the late zone emerged faster and more synchronously than those emerging from the early and mid zones. The species similarity between seed banks and standing vegetation was relatively high in the two most recent surveys (2020, 2013) compared to the initial survey (2007). However, the composition of life forms and regeneration strategies (i.e. sexual or vegetative reproduction) of seedlings that emerged from the soil seed banks was more similar to the composition of the initial standing vegetation survey (2007) than to the more recent surveys (2020, 2013). Our results suggest that although soil seed banks may be changing as the standing vegetation changes, they still have a compositional similarity to historical plant assemblages, contributing to the resilience of these endangered communities to climate change.</p></div>","PeriodicalId":51238,"journal":{"name":"Alpine Botany","volume":"135 1","pages":"135 - 147"},"PeriodicalIF":2.6,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00035-024-00321-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142175479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a six-year experiment to assess the responses of plant species richness, mean ecological indicator values, and vegetation composition to five management treatments, including scraping as additional management measure: haymaking (in autumn), haymaking complemented by scraping (i.e. manual raking) in autumn, haymaking complemented by scraping in spring, only scraping in spring, and abandonment of land use. We hypothesized that haymaking complemented by scraping in either season would remove additional biomass and increase species richness by creating open patches that can reduce inter-specific competition and promote species establishment. We found positive effects of haymaking complemented by scraping on plant species richness and habitat quality, indicated by the increased mean indicator value for light. Abandonment showed the opposite effects and increased mean indicator values for nutrients. Interestingly, haymaking combined with scraping in autumn promoted the development of the vegetation towards the composition similar to the resident vegetation type.
