Kalanchooideae) is the third largest genus recognised in the family. Madagascar is home to more than one third of the recognised taxa with the rest spread across Africa, and the Near, Middle, and Far East. In terms of growth form (trees, various types of shrubs, herbs, epiphytes; all leaf succulents), Madagascar also harbours the greatest diversity found in the genus. Several Malagasy species of Kalanchoe have attracted significant research interest from horticultural, (eco-)physiological and invasions biological perspectives. However, the species that occur beyond Madagascar have not been studied to the same degree. This review provides a synthesis of field observations made over several decades, especially in southern Africa, and of available information on several aspects of kalanchoe biology and ecology assembled from a wide range of sources. Such synthesised knowledge is important for, inter alia, informing conservation management strategies for wild kalanchoe populations, as well as more widely for the grassland and savanna and, to a lesser degree, forest and thicket, habitats in which the species mostly occur.","PeriodicalId":50726,"journal":{"name":"Bradleya","volume":"2022 1","pages":"161 - 184"},"PeriodicalIF":1.6,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45237163","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}

However, before attempting to conserve wild populations of any kind of animal or plant, it is important to know which taxa are involved and where they live, as this also allows us to identify the relevant hotspots and suggest the areas which need to be protected. In this paper the author presents a provisional checklist of taxa belonging to the Crassulaceae family, selected as a priority for conservation. This list itemises taxa with a restricted distribution (endemic) in a specific area of the Euro-Mediterranean biogeographical context. Only the taxa with a range confined to a single country of this geographic area are dealt with in this paper. The study also focused on taxa whose distribution is included in the political boundaries of a single nation, in order to connect them with the local ‘Red List’ and appropriate legislative measures. We have selected ninety-seven taxa divided between species and subspecies (varieties and hybrids are excluded), with details on their distribution (country and biogeographic area), category of endemism, and conservation references.","PeriodicalId":50726,"journal":{"name":"Bradleya","volume":"2022 1","pages":"83 - 104"},"PeriodicalIF":1.6,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43633559","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}

The plant, commonly called black lace cactus, is listed as a federally endangered species in the United States. The objectives of this study are to 1 – survey populations of black lace cactus to determine current occurrence status, 2 – examine habitat and morphological features of black lace cactus across occurrences and 3 – examine the phylogeny of the E. reichenbachii-fitchii species complex to decipher the closest evolutionary relatives of black lace cactus. We photo-documented E. fitchii subsp. albertii individuals and confirmed extant populations in Kleberg, McMullen, and Refugio counties, Texas. Our study identified additional populations extending the sub-species' distributional range into Atascosa and La Salle counties, Texas. Flower colour of E. fitchii subsp. albertii is characteristic of the E. fitchii group. Central spines are absent to rare in E. fitchii subsp. albertii individuals in most populations, with only plants growing in the Kleberg Co. population commonly exhibiting central spines. We used genome skimming and assembly of nuclear ribosomal regions and nearly complete chloroplast genomes to examine phylogenetic relationships of fifteen taxa of Echinocereus. The most significant finding emerging from this phylogenetic study is that two distinct chloroplast genome lineages can be distinguished in E. fitchii subsp. albertii. One lineage includes individuals from Refugio Co. and McMullen Co. populations which are most closely related to E. reichenbachii subsp. caespitosus. The other lineage includes individuals from Atascosa and Kleberg Cos., which are most closely related to E. fitchii subsp. fitchii. These two lineages are not defined by geographic proximity.","PeriodicalId":50726,"journal":{"name":"Bradleya","volume":"2022 1","pages":"27 - 48"},"PeriodicalIF":1.6,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45208222","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}
