We reinstate <jats:italic>T. canescens</jats:italic>, <jats:italic>T. hypericoides</jats:italic> and <jats:italic>T. nelsonii</jats:italic> based on differences in leaf, flower and fruit traits. Additionally, the Angolan population is proposed here as a new species of <jats:italic>Triapis</jats:italic> endemic to the dry miombo woodlands of Bicuar National Park, Huíla Province, southwestern Angola. <jats:italic>Triaspis bicuarensis</jats:italic> sp. nov. is easily distinguished from <jats:italic>T. nelsonii</jats:italic> by its alternate (versus opposite) leaves, ovate to widely ovate (versus widely ovate to very widely ovate) leaf laminas, rounded (versus sagittate) leaf base, flat (versus undulate) margins, sparsely white‐tomentose (versus glabrous to glabrescent) abaxial leaf surface, petiole 4–8 mm long (versus 2–3 mm long), compound inflorescences in thyrses (versus corymbs) and bracteoles inserted below apex of peduncles (versus in the middle of peduncles). An identification key to all species belonging to this species complex is presented alongside a complete morphological description for the new species, photographic plates and comments on the distribution, ecology, palynology and taxonomy.

Likewise, over the last two decades, the number of known species in Iran has tripled with the discovery of 16 additional species. Despite these noteworthy recent findings, there is a lack of an updated taxonomic revision that encompasses all these newcomers. This revision of the genus in Iran is based on comprehensive morphological examinations conducted on fresh plant material collected in the field, cultivated plants, herbarium specimens, and an extensive literature review. Presently, 24 species are recognized in Iran. They are classified into two sections: <jats:italic>Crocus</jats:italic> and <jats:italic>Nudiscapus</jats:italic>. Notably, 18 species (75%) are endemic to Iran, with 14 among them being steno‐endemics, the five remaining species are subendemic elements whose distribution is limited to Iran and the adjacent countries. An identification key to all 24 recognized species is presented, accompanied by illustrations, detailed descriptions, distribution maps and information on the conservation status of each species. According to the IUCN criteria, the conservation status of all species, excluding <jats:italic>C. caspius</jats:italic>, <jats:italic>C. damascenus,</jats:italic> <jats:italic>C. haussknechtii</jats:italic> and <jats:italic>C. michelsonii</jats:italic> is at an alarming level.

The annual mean temperature, mean temperature of the wettest quarter and annual precipitations were the most critical parameters that chiefly influence the distribution of <i>D. melanoxylon</i>. The ensemble model rendered high accuracy with AUC = 0.93, TSS = 0.74 and Kappa = 0.71. Past projections of <i>D. melanoxylon</i> indicated a widespread distribution during LGM and MH suggesting its adaptability to semi-dry as well as warm and humid climate, respectively. Presence of fossil pollen evidence of <i>D. melanoxylon</i> in the suitable habitats derived through past projections in this study complements the model results and marks occurrences of the species during LGM and MH. By 2050s and 2070s (RCP 8.5), there would be a decline in the distribution by only 0.4% (13 622 km²) and 0.2% (6842 km²) of the extremely suitable habitats, respectively. The main factor leading to reduced habitat suitability is the anticipated rise in temperature and variations in seasonal precipitation patterns. Our findings, help in identifying the parts of the country which would be severely affected by future climate change scenarios and plan conservation strategies for this commercially important species to facilitate its growth in suitable habitats which are likely to sustain under future climatic conditions.","PeriodicalId":54716,"journal":{"name":"Nordic Journal of Botany","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140172325","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}

We collected phenotypic data from herbarium specimens and garden‐grown plants of <jats:italic>S. autumnalis</jats:italic>, representing several habitats throughout Scandinavia and Iceland, and subjected progenies from controlled crosses within a subset of the common garden material to different temperature regimes to assess patterns of phenotypic plasticity. Our results strongly suggest that colour and indumentum of involucral bracts, as well as the size of capitula (measured by ligule length), are environmentally plastic and much affected by temperature. Reduced temperature resulted in significantly larger capitula, with both thicker and darker involucre indumentum. Since dark colouration, dense indumentum and large floral structures have been shown to facilitate heat retention and insect visitation in other plant species growing in cold climate, we hypothesize that plants of <jats:italic>S. autumnalis</jats:italic> benefit from possessing these features under cool conditions, and that much of the geographical variation in capitulum characters reflects adaptive phenotypic plasticity rather than ecotypic divergence.

Ecosystem restoration can mitigate the impacts from human land‐use change by assisting the recovery of natural ecosystems. We developed an assessment framework using established international standards and monitored alpine vegetation recovery within restored zones along a hydropower‐dam road built in 2013 in the Knutshø landscape protected area, Norway. Using data collected in 2016, 2018 and 2021, we compared abiotic variables and vegetation indicators (cover, and community composition) in restored zones against directly adjacent intact zones within three different habitat types. After eight years, wetland habitat had similar cover of plant functional types and abiotic variables within restored and intact zones, while ridge and willow‐heath habitats had more cover of graminoids and less cover of shrubs in restored compared to intact zones. In addition, community composition in restored wetland habitat zones was similar to intact zones, while the community composition of restored zones in ridge and willow‐heath habitats was significantly different from adjacent intact zones. This suggests that restored wetland habitat in our study system is on a trajectory of recovery, but that recovery of other plant community types may require longer periods of time or, in some cases, may not be possible without further intervention because of alternative stable states. Our results underscore the need for long‐term monitoring and adaptive management to insure restoration success in alpine environments.","PeriodicalId":54716,"journal":{"name":"Nordic Journal of Botany","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140128682","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}
