Lembrechts","doi":"10.1111/njb.04382","DOIUrl":"https://doi.org/10.1111/njb.04382","url":null,"abstract":"The contemporary interaction of climate and disturbance drives vegetation composition and species distribution shifts, making their respective roles difficult to disentangle. This study describes the long‐term ruderal plant species distributions along the ‘Rallarvägen' in Abisko, subarctic Sweden. This trail currently serves as a hiking trail but was initially created as a construction road for a railroad from 1898 to 1903 and is paralleled by the E10 Highway since 1982.Using vegetation and climate data from 1903, 1913, 1983, and 2021, we found that warm‐adapted ruderal plant species were common along the Rallarvägen shortly after railroad construction in the early 20th century. Interestingly, many of these native and non‐native ruderals with relatively high temperature affinity that were present in 1903 and 1913 have since disappeared and have not reappeared, despite the substantial increase in regional temperature in recent decades.In addition, the historical disturbances have had long‐lasting effects on the current spatial distribution of the ruderal vegetation. Most ruderals still reside close to the railroad tracks and are progressively filtered out with increasing distance from anthropogenically disturbed introductory points, such as train stations, where they peak in species richness – a process we term ‘horizontal directional ecological filtering', in parallel to the established concept of ‘directional ecological filtering' along elevational gradients.The historical record of ruderal plant species in the region, influenced by a century‐old railroad construction, emphasizes the importance of knowing a system's disturbance history for understanding current vegetation dynamics and anticipating its future in a changing climate.","PeriodicalId":54716,"journal":{"name":"Nordic Journal of Botany","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141510814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, the ontogeny of the diclinous flowers within the cage‐shaped inflorescences of the andromonoecious Dicyclophora persica Boiss. was studied using scanning electron microscopy (SEM), to determine if they follow the same ontogenetic processes. The development of an interesting, unusual club‐like organ in the center of the umbel was also studied. Our findings show that the floral organs in diclinous flowers follow the same pattern. Petals initiate in a clockwise direction, while stamens form in a helical pattern. The perfect central sessile flower in the umbellet, despite sepal suppression, was synchronized with inner staminate flowers in the initiation of petals, stamens, and carpels. In staminate flowers, two prominent sepals initiate after the inception of the stamens. Ovules only get aborted in the late stages. The club‐like organ initiates from a naked receptacle that has no resemblances to umbellets or flowers. In perfect flowers, the delayed initiation and prolonged spatial constraints are caused by bracts and massive staminate flowers which suppress the sepals and make them sessile. Considering the ovule suppression, staminate flowers may be adapted to prevent the perfect flowers from being exposed to extreme environmental conditions.","PeriodicalId":54716,"journal":{"name":"Nordic Journal of Botany","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141381618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
