Checklist of the Vascular Alien Flora of Catalonia (Northeastern Iberian Peninsula, Spain) Pere Aymerich1 & Llorenç Sáez2,3
BOTANICAL CHECKLISTS Mediterranean Botany ISSNe 2603-9109 https://dx.doi.org/10.5209/mbot.63608 Checklist of the vascular alien flora of Catalonia (northeastern Iberian Peninsula, Spain) Pere Aymerich1 & Llorenç Sáez2,3 Received: 7 March 2019 / Accepted: 28 June 2019 / Published online: 7 November 2019 Abstract. This is an inventory of the vascular alien flora of Catalonia (northeastern Iberian Peninsula, Spain) updated to 2018, representing 1068 alien taxa in total. 554 (52.0%) out of them are casual and 514 (48.0%) are established. 87 taxa (8.1% of the total number and 16.8 % of those established) show an invasive behaviour. The geographic zone with more alien plants is the most anthropogenic maritime area. However, the differences among regions decrease when the degree of naturalization of taxa increases and the number of invaders is very similar in all sectors. Only 26.2% of the taxa are more or less abundant, while the rest are rare or they have vanished. The alien flora is represented by 115 families, 87 out of them include naturalised species. The most diverse genera are Opuntia (20 taxa), Amaranthus (18 taxa) and Solanum (15 taxa). Most of the alien plants have been introduced since the beginning of the twentieth century (70.7%), with a strong increase since 1970 (50.3% of the total number). Almost two thirds of alien taxa have their origin in Euro-Mediterranean area and America, while 24.6% come from other geographical areas. The taxa originated in cultivation represent 9.5%, whereas spontaneous hybrids only 1.2%. From the temporal point of view, the rate of Euro-Mediterranean taxa shows a progressive reduction parallel to an increase of those of other origins, which have reached 73.2% of introductions during the last 50 years. -

Nuytsia the Journal of the Western Australian Herbarium 30: 1–18 Published Online 28 March 2019
J.M. Percy-Bower & C.M. Parker, Updates to Western Australia’s vascular plant census for 2018 1 Nuytsia The journal of the Western Australian Herbarium 30: 1–18 Published online 28 March 2019 SHORT COMMUNICATION Updates to Western Australia’s vascular plant census for 2018 The census database at the Western Australian Herbarium (PERTH), which provides the nomenclature for the website FloraBase (Western Australian Herbarium 1998–), lists current names and recent synonymy for Western Australia’s native and naturalised vascular plants, as well as algae, bryophytes, lichens, slime moulds and some fungi. The names represented in the census are either sourced from published research or denote as yet unpublished names based on herbarium voucher specimens. We herein summarise the changes made to vascular plant names in this database during 2018. One hundred and twenty-nine taxa were newly recorded for the State, of which 24 are naturalised and 41 have been added to the Threatened and Priority Flora list for Western Australia (Smith & Jones 2018; Western Australian Herbarium 1998–) (Table 1). A total of 185 name changes were made, including the formal publication of 29 phrase-named taxa (Table 2). Plant groups for which a number of name changes were made include Hydrocotyle L. (Perkins 2018a, 2018b), Drosera L. (Lowrie 2013a, 2013b, 2014), Lepilaena Harv. (Ito et al. 2016; Macfarlane et al. 2017) and Zygophyllum L. (transferred to Roepera A.Juss. following Beier et al. 2003). Numerous phrased-named taxa in the genus Baeckea L. were formally published under an expanded circumscription of Hysterobaeckea (Nied.) Rye (Rye 2018). Table 2 also includes cases where there has been a change of taxonomic concept, misapplication, exclusion or rank change. -
Population Dynamics of Translocated Frithia Humilis, an Endangered Sandstone Endemic
Population dynamics of translocated Frithia humilis, an endangered sandstone endemic PG Jansen 22174788 Dissertation submitted in fulfilment of the requirements for the degree Magister Scientiae in Environmental Sciences at the Potchefstroom Campus of the North-West University Supervisor: Prof SJ Siebert Co-supervisor: Dr F Siebert Assistant Supervisor: Prof J van den Berg May 2017 PREFACE Translocation of plants in South Africa is still poorly studied and seldom used as a conservation tool. Thus, the translocation of Frithia humilis for conservation purposes can be seen as a first for South Africa. Consequently, a monitoring programme was initiated to assess the feasibility of translocation as a conservation tool for this species. This study is considered to be the second phase of the monitoring program and aims to determine the long term feasibility of translocation, since the previous study determined whether F. humilis could survive the translocation process and successfully reproduce at the receptor sites. The objectives were to study the population to quantify and compare the: (i) pollination system over time and between receptor and control sites; (ii) fecundity over time and between receptor and control sites; and (iii) population structure over time and between receptor and control sites. The dissertation is divided into seven chapters. Chapter 1. Discusses project history, species account, aims and objectives, hypotheses and dissertation layout. Chapter 2. Discusses translocation challenges, factors influencing success and failure and guidelines. Chapter 3. Describes the study area, study sites and methodology. Chapter 4. The findings of observations and identification of potential pollinators are given and primary and reserve pollinators are suggested. -

Abstract Recent field and herbarium studies of the southern African genus Ursinia (Anthemideae, Asteraceae) in Namaqualand, South Africa, have revealed greater morphological variability than currently accommodated and a high percentage of mis- identified specimens. In an attempt to remedy this we herein describe four new species (Ursinia arida, U. glandulosa, U. kamiesbergensis and U. laciniata) and provide a key to the species in the region, together with illustrations of their involucral bracts and paleae. The species can be distinguished by a combination of their life history, vestiture, presence or absence of appendages on the paleae, and shape of the involucral bracts and their scarious apices. -
Plant Diversity Patterns at Different Spatial Scales in a Semi-Arid
Plant diversity patterns at different spatial scales in a semi-arid savanna ecosystem in central Namibia Jan Peters Diploma Thesis Landscape Ecology & Nature Conservation Ernst-Moritz-Arndt-Universität Greifswald October 2010 Supervised by: Prof. Dr. Michael Manthey (University of Greifswald) Dr. Jürgen Dengler (University of Hamburg) Preface In 2008, I had the chance to gather my first experiences on the African continent during an internship in Senegal. Returning home with a passion for the African nature, the landscapes and especially the people, the decision to work in this region again in the course of my further studies matured in my mind. This wish was fulfilled in the year 2009 when I got the opportunity to participate in the BIOTA project as a field assistant at the vegetation monitoring of various Observatories in Namibia. At the same time, I had the possibility to conduct my own field work as the basis for this thesis. The working group ' Biodiversity, Evolution, and Ecology of Plants ' at the Biocentre Klein Flottbek of the University of Hamburg faciliated the journey. Its staff works on the vegetation ecological part within the BIOTA subproject in southern Africa. Their research focuses are biodiversity patterns, their determining environmental factors and vegetation dynamics due to land use changes and climate change; therefore the topic of my thesis fits well into this context. In order to make the results of this thesis available for the international scientific community, it is written in the style of a scientific publication and in English language. For a better understanding, a German summary is preceded.
