The Capparaceae are a family of plants associated mainly with dry areas, which have produced climatic constraints and a limited geographic distribution. This family is considered endemic in the Neotropical seasonally dry forest (NSDF) and, therefore, a model to analyse the NSDF biogeography. We conducted a track analysis of Neotropical species of Capparaceae to identify generalised tracks that recover ancestral biotas of NSDF nuclei, employing 7602 data points for 104 species. Individual tracks were obtained using Prim’s algorithm and generalised tracks were identified using parsimony analysis of endemicity with progressive character elimination. We found six generalised tracks and four panbiogeographic nodes mainly located in the NSDF. Generalised tracks recovered the ancestral biotas of NSDF distributed among the central Andean coast, central inter-Andean valleys (Ecuador), Tarapoto–Quillabamba, Apurimac–Mantaro (Peru) and Piedmont (Bolivia) NSDF nuclei. Also, the pattern of distribution of Capparaceae recovered old connections between northern South America and the inter-Andean valleys. However, we also found generalised tracks located over the Isthmus of Panama and Amazonian–Magdalena valley moist forest, suggesting that the distribution pattern in this family was influenced not only by NSDF climatic constraints, but also by geological events such as the emergence of the Isthmus and Andean uplift.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":"33 1","pages":"129 - 136"},"PeriodicalIF":1.6,"publicationDate":"2020-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1071/SB18058","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49135114","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 Australian fern and lycophyte flora comprises 2 classes, 14 orders, 32 families, 134 genera and 528 species and subspecies with the addition of 8 newly recorded and 6 newly recognised species since the publication of the Flora of Australia fern volume in 1998. Overall, 208 species are endemic to Australia, with Queensland having the highest species diversity and endemism by state or territory, and Lord Howe Island having the highest concentration of species and endemics per unit area. The Australian fern and lycophyte flora shows diverse links with Africa, Asia and Oceania, with the largest overlaps being shared with Asia and Oceania. More species are endemic to Australia+Oceania than to Australia+Asia. Contrasting with the classification presented in the Flora of Australia, no genera of ferns and lycophytes are now considered to be wholly endemic to Australia.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":"33 1","pages":"1 - 102"},"PeriodicalIF":1.6,"publicationDate":"2020-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1071/sb18011","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43083823","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 genus Vachellia Wight & Arn. has a pantropical distribution, with species being distributed through Africa, the Americas, Asia and Australia. The relationships among the lineages from Africa and America are well understood, but the phylogenetic placement and evolutionary origins of the Australian species of Vachellia are not known. We, therefore, sequenced four plastid genes from representatives of each of the nine Australian species of Vachellia, and used Bayesian inference to assess the phylogenetic placement of these lineages, and a relaxed molecular clock to assess the timing of diversification. The Australian species of Vachellia form a well-supported monophyletic clade, with molecular-dating analysis suggesting a single dispersal into Australia 6.5 million years ago (95% range 13.9–2.7 million years ago). Diversification of the Australian clade commenced more recently, c. 3.1 million years ago (95% range 9.2–1.2 million years ago), perhaps driven by the increased aridification of Australia at this time. The closest relatives to the Australian Vachellia were not from the Malesian bioregion, suggesting either a long-distance dispersal from Africa, or two separate migrations through Asia. These results not only improve our understanding of the biogeography of Vachellia species, but also have significant implications for the biological control of invasive Vachellia species in Australia.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":"33 1","pages":"103 - 109"},"PeriodicalIF":1.6,"publicationDate":"2020-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1071/SB19013","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48594972","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}

Rutherford","doi":"10.1071/SB18042","DOIUrl":"https://doi.org/10.1071/SB18042","url":null,"abstract":"Abstract. Speciation is a central process in evolutionary biology and is responsible for the diversity of life on Earth. Although there has been much progress in evolutionary research over the past 150 years, understanding the many facets of speciation remains a challenge. In this synthesis, I focus on the use of an interdisciplinary approach to examine speciation and species delimitation in a group of closely related eucalypts called the green ashes (Eucalyptus subgenus Eucalyptus section Eucalyptus). The green ashes comprise tall trees on fertile soils (e.g. the tallest angiosperm in the world, E. regnans), as well as medium trees and mallees on low-nutrient soils. Previous phylogenetic and population-genetics analyses based on genome-wide scans showed that species boundaries in the green ashes are not always consistent with classifications based on morphology and there was evidence of gene flow across lineages. Genomic analyses also suggested that the green ashes were at varying stages of speciation, with some species being highly genetically differentiated, whereas others were at earlier stages on the speciation continuum. A previous common garden study showed that inter-specific differences in seedling traits were significant, with traits such as leaf width being highly plastic across resource treatments for most species. Overall, this synthesis demonstrated that an interdisciplinary approach incorporating phylogenomics, population genomics and a common garden experiment can provide insights into speciation and species delimitation in the green ash eucalypts. Such an approach may be useful in understanding the evolutionary history of other closely related species in Eucalyptus, as well as other groups of organisms.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":"33 1","pages":"110 - 127"},"PeriodicalIF":1.6,"publicationDate":"2020-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1071/SB18042","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47987065","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 anatomical analyses emphasised the characteristics of the steles in cross-sections of the root samples from regions near the apex to the most mature zones. A species of a closely related genus Adelonema, namely A. crinipes, was included in the study to clarify the results. Our results indicated notable differences in the species of the subgenus Meconostigma, mainly in terms of the presence (and variations) of a lobed stele, whereas the cylindrical stele stood out among the common characteristics in P. subg. Philodendron, P. subg. Pteromischum and the related species A. crinipes. Moreover, the characteristics shared by P. subg. Philodendron and P. subg.

These cyber-infrastructures have had a major impact on taxonomy and helped the discipline by allowing faster access to bibliographic information, biological and nomenclatural data, and specimen information. Several specialised portals aggregate particular data types for a large number of species, including legumes. Here, we argue that, despite access to such data-aggregation portals, a taxon-focused portal, curated by a community of researchers specialising on a particular taxonomic group and who have the interest, commitment, existing collaborative links, and knowledge necessary to ensure data quality, would be a useful resource in itself and make important contributions to more general data providers. Such an online species-information system focused on Leguminosae (Fabaceae) would serve useful functions in parallel to and different from international data-aggregation portals. We explore best practices for developing a legume-focused portal that would support data sharing, provide a better understanding of what data are available, missing, or erroneous, and, ultimately, facilitate cross-analyses and direct development of novel research. We present a history of legume-focused portals, survey existing data portals to evaluate what is available and which features are of most interest, and discuss how a legume-focused portal might be developed to respond to the needs of the legume-systematics research community and beyond. We propose taking full advantage of existing data sources, informatics tools and protocols to develop a scalable and interactive portal that will be used, contributed to, and fully supported by the legume-systematics community in the easiest manner possible.","PeriodicalId":55416,"journal":{"name":"Australian Systematic Botany","volume":"32 1","pages":"495 - 518"},"PeriodicalIF":1.6,"publicationDate":"2019-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1071/SB19025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46743232","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}
