Rates of Molecular Evolution and Diversification in Plants: Chloroplast
Duchene and Bromham BMC Evolutionary Biology 2013, 13:65 http://www.biomedcentral.com/1471-2148/13/65 RESEARCH ARTICLE Open Access Rates of molecular evolution and diversification in plants: chloroplast substitution rates correlate with species-richness in the Proteaceae David Duchene* and Lindell Bromham Abstract Background: Many factors have been identified as correlates of the rate of molecular evolution, such as body size and generation length. Analysis of many molecular phylogenies has also revealed correlations between substitution rates and clade size, suggesting a link between rates of molecular evolution and the process of diversification. However, it is not known whether this relationship applies to all lineages and all sequences. Here, in order to investigate how widespread this phenomenon is, we investigate patterns of substitution in chloroplast genomes of the diverse angiosperm family Proteaceae. We used DNA sequences from six chloroplast genes (6278bp alignment with 62 taxa) to test for a correlation between diversification and the rate of substitutions. Results: Using phylogenetically-independent sister pairs, we show that species-rich lineages of Proteaceae tend to have significantly higher chloroplast substitution rates, for both synonymous and non-synonymous substitutions. Conclusions: We show that the rate of molecular evolution in chloroplast genomes is correlated with net diversification rates in this large plant family. We discuss the possible causes of this relationship, including molecular evolution driving diversification, speciation increasing the rate of substitutions, or a third factor causing an indirect link between molecular and diversification rates. The link between the synonymous substitution rate and clade size is consistent with a role for the mutation rate of chloroplasts driving the speed of reproductive isolation. -
(OUV) of the Wet Tropics of Queensland World Heritage Area
Handout 2 Natural Heritage Criteria and the Attributes of Outstanding Universal Value (OUV) of the Wet Tropics of Queensland World Heritage Area The notes that follow were derived by deconstructing the original 1988 nomination document to identify the specific themes and attributes which have been recognised as contributing to the Outstanding Universal Value of the Wet Tropics. The notes also provide brief statements of justification for the specific examples provided in the nomination documentation. Steve Goosem, December 2012 Natural Heritage Criteria: (1) Outstanding examples representing the major stages in the earth’s evolutionary history Values: refers to the surviving taxa that are representative of eight ‘stages’ in the evolutionary history of the earth. Relict species and lineages are the elements of this World Heritage value. Attribute of OUV (a) The Age of the Pteridophytes Significance One of the most significant evolutionary events on this planet was the adaptation in the Palaeozoic Era of plants to life on the land. The earliest known (plant) forms were from the Silurian Period more than 400 million years ago. These were spore-producing plants which reached their greatest development 100 million years later during the Carboniferous Period. This stage of the earth’s evolutionary history, involving the proliferation of club mosses (lycopods) and ferns is commonly described as the Age of the Pteridophytes. The range of primitive relict genera representative of the major and most ancient evolutionary groups of pteridophytes occurring in the Wet Tropics is equalled only in the more extensive New Guinea rainforests that were once continuous with those of the listed area. -

Report on the Vegetation of the Proposed Blue Hole Cultural, Environmental & Recreation Reserve
Vegetation Report on the Proposed Blue Hole Cultural, Environmental & Recreation Reserve Report on the Vegetation of the Proposed Blue Hole Cultural, Environmental & Recreation Reserve 1.0 Introduction The area covered by this report is described as the proposed Lot 1 on SP144713; Parish of Alexandra; being an unregistered plan prepared by the C & B Group for the Douglas Shire Council. This proposed Lot has an area of 1.394 hectares and consists of the Flame Tree Road Reserve and part of a USL, which is a small portion of the bed of Cooper Creek. It is proposed that the Flame Tree Road Reserve and part of the USL be transferred to enable the creation of a Cultural, Environmental and Recreation Reserve to be managed in Trust by the Douglas Shire Council. The proposed Cultural, Environmental and Recreation Reserve will have an area of 1.394 hectares and will if the plan is registered become Lot 1 of SP144713; Parish of Alexandra; County of Solander. It is proposed that three Easements A, B & C over the proposed Lot 1 of SP144713 be created in favour of Lot 180 RP739774, Lot 236 RP740951, Lot 52 of SR537 and Lot 51 SR767 as per the unregistered plan SP 144715 prepared by the C & B Group for the Douglas Shire Council. 2.0 Trustee Details Douglas Shire Council 64-66 Front Street Mossman PO Box 357 Mossman, Qld, 4873 Phone: (07) 4099 9444 Fax: (07) 4098 2902 Email: [email protected] Internet: www.dsc.qld.gov.au 3.0 Description of the Subject Land The “Blue Hole” is a local name for a small pool in a section of Cooper Creek. -
I Is the Sunda-Sahul Floristic Exchange Ongoing?
Is the Sunda-Sahul floristic exchange ongoing? A study of distributions, functional traits, climate and landscape genomics to investigate the invasion in Australian rainforests By Jia-Yee Samantha Yap Bachelor of Biotechnology Hons. A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2018 Queensland Alliance for Agriculture and Food Innovation i Abstract Australian rainforests are of mixed biogeographical histories, resulting from the collision between Sahul (Australia) and Sunda shelves that led to extensive immigration of rainforest lineages with Sunda ancestry to Australia. Although comprehensive fossil records and molecular phylogenies distinguish between the Sunda and Sahul floristic elements, species distributions, functional traits or landscape dynamics have not been used to distinguish between the two elements in the Australian rainforest flora. The overall aim of this study was to investigate both Sunda and Sahul components in the Australian rainforest flora by (1) exploring their continental-wide distributional patterns and observing how functional characteristics and environmental preferences determine these patterns, (2) investigating continental-wide genomic diversities and distances of multiple species and measuring local species accumulation rates across multiple sites to observe whether past biotic exchange left detectable and consistent patterns in the rainforest flora, (3) coupling genomic data and species distribution models of lineages of known Sunda and Sahul ancestry to examine landscape-level dynamics and habitat preferences to relate to the impact of historical processes. First, the continental distributions of rainforest woody representatives that could be ascribed to Sahul (795 species) and Sunda origins (604 species) and their dispersal and persistence characteristics and key functional characteristics (leaf size, fruit size, wood density and maximum height at maturity) of were compared. -

John A. Stevenson's "Foreign Plant Diseases" (U.S. Dept. Agr. unnumbered publication, 198 pp., 1926) has served as a reliable guide. Information on the occurrence of tree diseases in the United States has been obtained from the "Index of Plant Dis- eases in the United States" by Freeman Weiss and Muriel J. O'Brien (U.S. Dept. Agr. Plant Dis. Survey Spec. Pub. 1, Parts I-V, 1263 pp., 1950-53). The author wishes to express liis appreciation to Dean George A. Garratt for providing free access to the library of the School of Forestry, Yale University. The Latin names and authorities for the trees were verified by Elbert L. Little, Jr., who also checked the common names and, where possible, supplied additional ones. His invaluable assistance is grate- fully acknowledged. To Bertha Mohr special thanks are due for her assistance, enabling the author to complete a task so arduous that no one else has attempted it. For sale by the Superintendent of Documents, iTs.
