However, in Peninsular Malaysia limestone outcrops are heavily exploited for the quarry industry, cave temples, leisure venues and the development of geoparks, hence the limestone flora is amongst the most threatened biodiversity in the Peninsula. The 95 limestone karsts in Perak are currently known to support 538 species, representing c. 44.2% of the total limestone flora of Peninsular Malaysia. Of these, 13.2% (71 species) are endemic to the Peninsula of which 10 species are hyper-endemic (i.e. restricted to a single karst), 108 (20%) are threatened with extinction and 6 are considered likely to be Extinct. Typical of limestone in Peninsular Malaysia, a single karst harbours only a fraction of the total limestone flora such that a network of karsts is required to capture maximum plant diversity. Through evaluation of data from field surveys, herbarium specimens and the literature, 27 of the Perak karsts were found to trigger Important Plant Area (IPA) status, i.e. they harbour important populations of threatened species, outstanding botanical richness and/or are important examples of threatened habitats that in Perak include the foothills and limestone forest. Fifteen karsts were identified for priority conservation measures based on Conservation Priority Scores (CPS), a quantitative methodology based on endemic and threatened status. With the addition of two species-rich karst sites, 17 karsts are recommended as the first iteration of the network of priority IPA sites for Perak that together conserve 90% (483 species) of the Perak limestone plant diversity, 93% (66) of the endemic species and 94.4% (102) of the threatened species. CPS is found to be more reliable than using total species richness for assessing conservation importance and we also demonstrate that karst size and isolation are not primary indicators of range-restricted plant diversity. Significant knowledge gaps still exist, with 59 karsts in Perak without botanical surveys, and with many rare species having not been recollected for over 30 years, emphasising the need for further botanical research in these important and threatened landscapes.</p>","PeriodicalId":51321,"journal":{"name":"Kew Bulletin","volume":"140 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140940959","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}

Meades, Ian Denholm, Daniel Tyteca, Mikael Hedrén","doi":"10.1007/s12225-024-10176-6","DOIUrl":"https://doi.org/10.1007/s12225-024-10176-6","url":null,"abstract":"<p>Between 1959 and 1988, three populations of purple-flowered terrestrial orchids attributable to <i>Dactylorhiza</i> subgenus <i>Dactylorhiza</i> were discovered in Canada. The populations at Timmins, Ontario, and St John's, Newfoundland were strongly marked on both flowers and leaves, in contrast with the anthocyanin-deficient population at Tilt Cove, Newfoundland. All three populations have since experienced a wide range of taxonomic assignments; debates are also ongoing regarding their origin and most appropriate conservation status. Here, we address these questions by combining detailed in situ morphometric analyses based on 52 characters with allozyme profiles and data from nrITS, 15 plastid microsatellites and seven nuclear microsatellites. The allozyme data alone are sufficient to both confirm allopolyploidy and categorically refute past assignments of these populations to <i>D. incarnata</i>, <i>D. maculata</i>, <i>D. fuchsii</i>, <i>D. majalis</i> or <i>D. purpurella</i>. Several morphometric characters, nuclear microsatellites and nrITS all reliably distinguish each of the three study populations, whereas the two sampled subpopulations from St John's proved near-identical morphologically. In contrast, morphological variation within each of the three populations is strikingly low, particularly in characters other than those influenced by plant vigour. Similarly, compared with 14 European populations, the three Canadian populations proved genetically impoverished (two were near-invariant) and likely experienced recent, extreme genetic bottlenecks during establishment. The three populations differ substantially, both morphologically and molecularly, therefore probably representing independent immigration events. Although clearly attributable to <i>D. praetermissa</i>, all three populations deviate significantly in morphology and DNA data from comparable populations sampled across Europe, preventing identification of their precise geographic origins. Any attempt to determine their mode or origin — through natural long-distance transport, or accidental or deliberate introduction by humans – is challenged to explain why three lineages of a single European Marsh-orchid species, each in different ways atypical of that species, arrived independently in North America whereas no other European dactylorchid species has become established there.</p>","PeriodicalId":51321,"journal":{"name":"Kew Bulletin","volume":"77 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140940970","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}
