This phenomenon has been attributed to allelopathy; one of the strategies used by A. dealbata to trigger an invasion process. Native species Quillaja saponaria Molina (tree) and Helenium aromaticum (Hook.) H.L. Bailey (herb), share A. dealbata’s range in South-central Chile. This study was performed on the Mediterranean Biobío Region of Chile. We evaluated the effect of leaves, flowers, pods and seeds of A. dealbata on the germination and early growth of these native species. -

Impacts of Land Use on Biodiversity: Development of Spatially Differentiated Global Assessment Methodologies for Life Cycle Assessment
DISS. ETH NO. xx Impacts of land use on biodiversity: development of spatially differentiated global assessment methodologies for life cycle assessment A dissertation submitted to ETH ZURICH for the degree of Doctor of Sciences presented by LAURA SIMONE DE BAAN Master of Sciences ETH born January 23, 1981 citizen of Steinmaur (ZH), Switzerland accepted on the recommendation of Prof. Dr. Stefanie Hellweg, examiner Prof. Dr. Thomas Koellner, co-examiner Dr. Llorenç Milà i Canals, co-examiner 2013 In Gedenken an Frans Remarks This thesis is a cumulative thesis and consists of five research papers, which were written by several authors. The chapters Introduction and Concluding Remarks were written by myself. For the sake of consistency, I use the personal pronoun ‘we’ throughout this thesis, even in the chapters Introduction and Concluding Remarks. Summary Summary Today, one third of the Earth’s land surface is used for agricultural purposes, which has led to massive changes in global ecosystems. Land use is one of the main current and projected future drivers of biodiversity loss. Because many agricultural commodities are traded globally, their production often affects multiple regions. Therefore, methodologies with global coverage are needed to analyze the effects of land use on biodiversity. Life cycle assessment (LCA) is a tool that assesses environmental impacts over the entire life cycle of products, from the extraction of resources to production, use, and disposal. Although LCA aims to provide information about all relevant environmental impacts, prior to this Ph.D. project, globally applicable methods for capturing the effects of land use on biodiversity did not exist. -

Here, we define the distribution and extent of genomic diversity across the range of the iconic but threatened Acacia purpureopetala, a beautiful sprawling shrub with mauve flowers, restricted to a few disjunct populations in far north Queensland, Australia. Seed production is poor and germination sporadic, but the species occurs in abundance at some field sites. While several thousands of SNP markers were recovered, comparable to other Acacia species, very low levels of heterozygosity and allelic variation suggested inbreeding. Limited dispersal most likely contributed towards the high levels of divergence amongst field sites and, using a generalised dissimilarity modelling framework amongst environmental, spatial and floristic data, spatial distance was found to be the strongest factor explaining the current distribution of genetic diversity. We illustrate how population genomic data can be utilised to design Citation: van der Merwe, M.M.; Yap, a collecting strategy for a germplasm conservation collection that optimises genetic diversity. -

11Th Flora Malesina Symposium, Brunei Darussalm, 30 June 5 July 2019 1
11TH FLORA MALESINA SYMPOSIUM, BRUNEI DARUSSALM, 30 JUNE 5 JULY 2019 1 Welcome message The Universiti Brunei Darussalam is honoured to host the 11th International Flora Malesiana Symposium. On behalf of the organizing committee it is my pleasure to welcome you to Brunei Darussalam. The Flora Malesiana Symposium is a fantastic opportunity to engage in discussion and sharing information and experience in the field of taxonomy, ecology and conservation. This is the first time that a Flora Malesiana Symposium is organized in Brunei Darissalam and in the entire island of Borneo. At the center of the Malesian archipelago the island of Borneo magnifies the megadiversity of this region with its richness in plant and animal species. Moreover, the symposium will be an opportunity to inspire and engage the young generation of taxonomists, ecologists and conservationists who are attending it. They will be able to interact with senior researchers and get inspired with new ideas and develop further collaboration. In a phase of Biodiversity crisis, it is pivotal the understanding of plant diversity their ecology in order to have a tangible and successful result in the conservation action. I would like to thank the Vice Chancellor of UBD for supporting the symposium. In the last 6 months the organizing committee has worked very hard for making the symposium possible, to them goes my special thanks. I would like to extend my thanks to all the delegates and the keynote speakers who will make this event a memorable symposium.

Synoptic Overview of Exotic Acacia, Senegalia and Vachellia (Caesalpinioideae, Mimosoid Clade, Fabaceae) in Egypt
plants Article Synoptic Overview of Exotic Acacia, Senegalia and Vachellia (Caesalpinioideae, Mimosoid Clade, Fabaceae) in Egypt Rania A. Hassan * and Rim S. Hamdy Botany and Microbiology Department, Faculty of Science, Cairo University, Giza 12613, Egypt; [email protected] * Correspondence: [email protected] Abstract: For the first time, an updated checklist of Acacia, Senegalia and Vachellia species in Egypt is provided, focusing on the exotic species. Taking into consideration the retypification of genus Acacia ratified at the Melbourne International Botanical Congress (IBC, 2011), a process of reclassification has taken place worldwide in recent years. The review of Acacia and its segregates in Egypt became necessary in light of the available information cited in classical works during the last century. In Egypt, various taxa formerly placed in Acacia s.l., have been transferred to Acacia s.s., Acaciella, Senegalia, Parasenegalia and Vachellia. The present study is a contribution towards clarifying the nomenclatural status of all recorded species of Acacia and its segregate genera. This study recorded 144 taxa (125 species and 19 infraspecific taxa). Only 14 taxa (four species and 10 infraspecific taxa) are indigenous to Egypt (included now under Senegalia and Vachellia). The other 130 taxa had been introduced to Egypt during the last century. Out of the 130 taxa, 79 taxa have been recorded in literature. The focus of this study is the remaining 51 exotic taxa that have been traced as living species in Egyptian gardens or as herbarium specimens in Egyptian herbaria. The studied exotic taxa are accommodated under Acacia s.s. (24 taxa), Senegalia (14 taxa) and Vachellia (13 taxa). -

Using some or many of these mapped phenomena, classifications of natural regions, biomes, biotic provinces, biogeographical regions, life zones, or ecological regions have been developed by various researchers. Some ecological frameworks do not appear to address “the whole ecosystem”, but instead are based on specific aspects of ecosystems or particular processes that affect ecosystems. Many regional ecological frameworks rely primarily on climatic and “natural” vegetative input elements, with little acknowledgement of other biotic, abiotic, or human geographic patterns that comprise and influence ecosystems.
