ABSTRACT Aims Australia's coastline is fringed by more than 8000 continental islands. These islands feature a diverse array of landforms, rock and soil types geological origins. Some these are among the least invaded, most pristine habitats in Australia support high plant diversity. Here, we present new Australia‐wide curated dataset for species occurrences on Results Combining information from 1349 lists floras, A‐Islands includes data > 6500 844 ranging size 18 m 2 to 4400 km ,...
The introduction and subsequent impact of Phytophthora cinnamomi within native vegetation is one the major conservation issues for biodiversity in Australia. Recently, many new species have been described from Australia’s ecosystems; however, their distribution, origin, potential remain unknown. Historical bias detection has towards sites showing symptoms disease, traditional isolation methods show variable effectiveness detecting different species. However, we now at our disposal techniques...
Species radiations, despite immense phenotypic variation, can be difficult to resolve phylogenetically when genetic change poorly matches the rapidity of diversification. Genomic potential furnished by palaeopolyploidy, and relative roles for adaptation, random drift hybridisation in apportionment remain understood factors. Here, we study these aspects a model radiation, Syzygium, most species-rich tree genus worldwide. Genomes 182 distinct species 58 unidentified taxa are compared against...
Pod rot and stem canker, caused by Phytophthora palmivora , are serious diseases of cocoa causing pod losses up to 63% the death 10% trees annually on Kar Island. Papua New Guinea. Trials were conducted commercial plantations compare effectiveness potassium phosphonate when applied as trunk injections, paints foliar sprays, injections Aliette CA Ridomil 250EC, with conventional Ridomil‐based spray programmes. The results show that, in trials over 5 years, give highest healthy yield lowest...

Context Australia’s tropical montane cloud forests (TMCF) exhibit exceptional species richness and endemism. Determinants of regeneration via seed these are next to unknown, limiting our ability quantify project their vulnerability climate change. The ratio red far-red light (R:FR) has been shown influence germination many species. Aims We investigated six previously unstudied TMCF in relation the presence or absence (light/dark) quality (R:FR). hypothesised that increased R:FR would lead...
Abstract Idiospermum australiense (Diels) S. T. Blake, is a rare species that produces very large diaspores (up to 225 g) comprising 2–6 cotyledons. Anecdotal evidence suggested each cotyledon within the diaspore could develop an independent root/shoot axis in natural populations and under glasshouse conditions. To investigate this potential, 13 were collected. Six kept intact cotyledons remaining seven separated, planted into soil scored for germination. All shoots allowed grow 12 weeks....
Context Seed dormancy is one issue hindering implementation of conservation actions for rainforest species. Aims We studied and germination in Tasmannia sp. Mt Bellenden Ker membranea, two tropical montane species threatened by climate change, to develop a better understanding the genus. Methods Dormancy was classified T. on basis an imbibition test, analysis embryo seed length (E:S) ratios response following four dormancy-breaking treatments: (1) scarification seedcoat near micropylar end;...
Two additional species of the liverwort genus Chiastocaulon Carl, namely, C. fasciculatum M.A.M.Renner sp. nov. and pachycephalum (De Not.) Herzog, are reported from two mountain tops in north Queensland Wet Tropics Bioregion, Mount Finnigan Thornton Peak. Given recent completion a revision for Australia, new provides another cogent demonstration that bryophyte flora Bioregion is incompletely explored documented. The similar to dendroides (Nees) but can be distinguished by leaf shape...

Abstract Species radiations have long fascinated biologists, but the contribution of adaptation to observed diversity and speciation is still an open question. Here, we explore this question using clove genus, Syzygium, world’s largest genus tree species comprising approximately 1200 species. We dissect Syzygium through shotgun sequencing 182 distinct 58 additional as-yet unidentified taxa, assess their genetic against a chromosome-level reference genome sea apple, grande. show that grande...
