Special Relevance

The value of distinguishing between plant species regarded as ‘native’ and ‘alien’ has special relevance in the island continent of Australia, where European settlement was a springboard for human-assisted plant dispersal. The year of European settlement is proposed here as providing a distinction between a ‘native’ and ‘naturalised’ flora and is applied for the entire Australian flora of vascular plants. Herbarium collections and ecological criteria were employed to determine the status of 168 species of ambiguous origin. The date of 1788 proved to be a relatively straightforward criterion to assign native and naturalised status and the origin of only 27 plant species remains ambiguous. The dispersal of plants between continents is an ongoing process but European settlement of the Australian continent represents a very sharp biogeographic event for the Australian flora and provides a straightforward criterion for determining the ‘naturalised’ species.

Background: The first checklist for the Soutpansberg was published in 1946, and the second list was compiled by the author in 2006 as part of his doctoral thesis. Currently, there is a need for an updated account of the biodiversity of the Soutpansberg Centre of Endemism and Diversity for conservation planning in the Vhembe Biosphere Reserve, within which the Soutpansberg is the principle geomorphological feature.Objectives: To present an updated list of vascular plants recorded for the Soutpansberg.Method: The list was compiled from various sources including literature reviews, herbarium specimens, herbarium databases and personal observations.Results: This article presents the most geographically accurate and taxonomically updated list of the indigenous vascular flora of the Soutpansberg, the northernmost mountain range of South Africa. Altogether 2443 taxa are recorded belonging to 922 genera in 187 families and 64 orders.Conclusion: The list presented in this article confirms the status of the Soutpansberg as a centre of floristic diversity in southern Africa. Notable is the higher-order diversity of the flora. It is likely that both future surveys and reviews of herbarium collections will add new taxa to the current total.

Изучение разнообразия охраняемой флоры в заповеднике Нам Донг (северный Вьетнам) проведено в рамках флористических исследований территории в 2015–2019 гг. Исследование проводилось на семи профилях, заложенных от самых низких высот над уровнем моря до высшей точки изучаемой территории, с таким расчетом, чтобы максимально охватить возможное число местообитаний на склонах разной экспозиции. Флористические исследования позволили уточнить состав редких и охраняемых видов растений территории, имеющих международный или национальный природоохранный статус. К таким растениям в заповеднике относятся 88 видов (6,7% от всей местной флоры), принадлежащих к 51 семейству (28,3% от 180 семейств флоры). Охраняемые виды относятся к трем отделам сосудистых растений: Polypodiophyta – 5 видов (5,7%), Pinophyta – 10 (11,4%), Magnoliophyta – 73 (83,0%). Из них 57 видов занесены в список МСОП (IUCN), в т.ч. EN (исчезающие) – 7 (8,0%), VU (уязвимые) – 11 (12,5%), NT (находящиеся в состоянии, близком к угрожаемому) – 7 (8,0%), LC (вызывающие наименьшие опасения) – 32 (36,4%), DD (требующие дополнительных исследований) – 2 (2,3%); 43 вида охраняется в соответствии с Красной книгой Вьетнама (2007), в том числе EN – 11 (12,5%), VU – 32 (36,4%); 18 видов – в соответствии с Постановлением об охране редких и ценных видов флоры и фауны Вьетнама (2006). 37 видов, входящих в список МСОП, не охраняются во Вьетнаме. Однако 10 видов из этого списка со статусом EN, VU, NT могут составить ресурсную базу для реинтродукции их на территории, где виды исчезли или находятся на стадии полного вымирания. The study of the diversity of protected flora in the Nam Dong Nature Reserve (North Vietnam) was carried out as part of the study of the territory's flora in 2015–2019. The study was carried out on 7 profiles, laid down from the lowest heights to the highest point of the studied territory, in such a way that it would cover the maximum possible number of habitats on the slopes of different exposures. Floristic studies have made it possible to clarify the composition of rare and protected plant species of the territory that have international or national conservation status. Such plants in the reserve include 88 species (6.71% of all local flora) belonging to 51 families (28.33% of 180 flora families). Protected species belong to 3 divisions of vascular plants: Polypodiophyta – 5 species (5.68%), Pinophyta – 10 (11.36%), Magnoliophyta – 73 (82.95%). Of these, 57 species are listed in the IUCN (IUCN), including EN (endangered) – 7 (7.95%), VU (vulnerable) – 11 (12.50%), NT (near-threatened) – 7 (7.95%), LC (least concern) – 32 (36.36%), DD (requiring additional research) – 2 (2.27%); 43 species are protected in accordance with the Red Book of Vietnam (2007), including EN – 11 (12.50%), VU – 32 (36.36%); 18 species – in accordance with the Decree on of the Government on management of endangered, precious and rare forest plants and animals (2006). 37 species included in the IUCN list are not protected in Vietnam. However, 10 species from this list with the status EN, VU, NT, can form a resource base for their reintroduction in the territory where the species have disappeared or are at the stage of complete extinction.

Background and aims – Located in the transition zone of Guineo-Congolian and Zambezian phytochoria, the Angolan provinces of Uíge and Cuanza Norte are of particular interest for floristic studies and high biodiversity is expected. Nevertheless, explorations of the vegetation are relatively rare. Our study aims to supplement a recent checklist of vascular plants of Angola. Methods – Data were collected during 17 field trips between 2013 and 2018, during which herbarium specimens were prepared for later identification of plant species. The results were compared with the current checklist as well as with other floristic works, herbarium collections and online databases relevant for the region.Key results – We document 20 new records of indigenous vascular plant species for the flora of Angola (19 species and one subspecies), including four new generic records. Furthermore, nine alien species are added to the checklist of the flora of Angola.Conclusion – Our results confirm that the flora of northern Angola is composed by elements of various adjacent areas. However, not all species present are known yet. Further botanical investigation is needed to complete our floristic knowledge of the region.

Different Levels

Nowadays, bioecological characteristics of species are the basis for flora and vegetation studying on the different levels. Bioecological characteristics of species is required in process of flora studying on the different levels such as biotopes or phytocenoses, floras of particular areas (floras of ecologically homogeneous habitats), and floras of certain territories. Ramensky scale is the one of first detailed ecological scales on plant species ordination in relation to various environmental factors; it developed in 1938 (Ramensky, 1971). A little later (1941), Pogrebnyak’s scale of forest stands was proposed. Ellenberg’s system developed in 1950 (Ellenberg, 1979) and Tsyganov’s system (Tsyganov, 1975) are best known as the systems of ecological scales on vascular plant species; these systems represent of habitat detection by ecotopic ecomorphs of plant species (phytoindication). Basically, the system proposed by Alexander Lyutsianovich Belgard was the one of first system of plant species that identiified ectomorphs in relation to environmental factors. As early as 1950, Belgard developed the tabulated system of ecomorphs using the Latin ecomorphs abbreviation; he also used the terminology proposed in the late 19th century by Dekandol (1956) and Warming (1903), as well as terminology of other authors. The article analyzes the features of Belgard’s system of ecomorphs on vascular plants. It has certain significance and advantages over other systems of ecomorphs. The use of abbreviated Latin names of ecomorphs in tabular form enables the use shortened form of ones. In the working scheme of Belgard’s system of ecomorphs relation of species to environmental factors are represented in the abbreviated Latin alphabetic version (Belgard, 1950). Combined into table, the ecomorphic analysis of plant species within association (ecological certification of species), biotope or area site (water area) gives an explicit pattern on ecological structure of flora within surveyed community, biotope or landscape, and on environmental conditions. Development and application by Belgrard the cenomorphs as «species’ adaptation to phytocenosis as a whole» were completely new in the development of systems of ecomorphs and, in this connection, different coenomorphs were distinguished. Like any concept, the system of ecomorphs by Belgard has the possibility and necessity to be developed and added. Long-time researches and analysis of literature sources allow to propose a new coenomorph in the context of Belgard’s system of ecomorphs development: silvomargoant (species of forest margin, from the Latin words margo – edge, boundary (Dvoretsky, 1976), margo – margin, ad margins silvarum – along the deciduous forest margins). As an example of ecomorphic characterization of species according to the system of ecomorphs by Belgard (when the abbreviated Latin ecomorph names are used in tabular form and the proposed cenomorph is used), it was given the part of the table on vascular plants ecomorphs in the National Nature Park «Orelsky» (Baranovsky et al). The Belgard’s system of ecomorphs is particularly convenient and can be successfully applied to data processing in the ecological analysis of the flora on wide areas with significant species richness, and the proposed ecomorph will be another necessary element in the Belgard’s system of ecomorphs.

Elevational Distribution

AbstractThe climate is changing rapidly, and this may pose a major threat to global biodiversity. One of the most distinctive consequences of climate change is the poleward and/or upward shift of species distribution ranges associated with increasing temperatures, resulting in a change of species composition and community structure in the forest ecosystems. The Baekdudaegan mountain range connects most forests from the lowland to the subalpine zone in South Korea and is therefore recognized as one of the most important biodiversity hotspots. This study was conducted to understand the distribution range of vascular plants along elevational gradients through field surveys in the six national parks of the Baekdudaegan mountain range. We identified the upper and lower distribution limits of a total of 873 taxa of vascular plants with 117 families, 418 genera, 793 species, 14 subspecies, 62 varieties, two forms, and two hybrids. A total of 12 conifers were recorded along the elevational gradient. The distribution ranges of Abies koreana, Picea jezoensis, Pinus pumila, and Thuja koraiensis were limited to over 1000 m above sea level. We also identified 21 broad-leaved trees in the subalpine zone. A total of 45 Korean endemic plant species were observed, and of these, 15 taxa (including Aconitum chiisanense and Hanabusaya asiatica) showed a narrow distribution range in the subalpine zone. Our study provides valuable information on the current elevational distribution ranges of vascular plants in the six national parks of South Korea, which could serve as a baseline for vertical shifts under future climate change.

Buildings were constructed and artefacts left behind on sub-Antarctic Heard Island, associated with Antarctic research expeditions since 1926. Both bryophytes and vascular plants are colonising many parts of the now derelict buildings. On these structures and artefacts, the authors recorded four species of vascular plants out of the 11 that occur on Heard Island and nine species of mosses out of the 37 recorded from Heard Island. The vascular plant species most frequently recorded colonising structures and artefacts was Pringlea antiscorbutica (288 occurrences), with the area colonised varying from 0.3 cm2 to 430.0 cm2. Muelleriella crassifolia was the moss species that was most frequently recorded (14 occurrences), colonising areas from 2.1 cm2 to 12.9 cm2. The highest number of bryophyte species (seven) was recorded on the stone and cement of the ‘water tank.’ Pringlea antiscorbutica, Poa cookii, Azorella selago, Muelleriella crassifolia, Bryum dichotomum, Dicranoweisia brevipes and Schistidium apocarpum are all expected to continue to colonise the ANARE ruins, as well as areas that have become available since building removal and also possibly areas bared by further deglaciation.

The problem of invasion of Sosnowsky hogweed (Heracleum sosnowskyi Manden.) In the Lipovaya Gora SPNA in Perm is considered. A map of distribution of hogweed cenopopulations in the protected area is presented. The results of the influence of the invasion of Sosnovsky hogweed on the biodiversity of vascu-lar plants of some plant communities are presented. It was revealed that the invasion of hogweed into phytocenoses of the Lipovaya Gora protected area leads to a decrease in the biodiversity of vascular plants by about 26.4% (up to 12 plant species). The ways of introduction of cow parsnip into the communities of the protected area are considered. High seed productivity, high projective cover, reaching in some cases 100%, high phytomass, the presence of dormant seeds, rapid development in spring, and high anthropo-genic load on the territory determine the rapid spread of H. sosnowskyi.

Cabomba schwartzii was described by Rataj in 1977. The species discovered in the Brazilian Amazon was said to differ from other Cabomba species in having two sepals, two petals and a lobate petal base. According to the 1991 study of Ørgaard, C. schwartzii is similar to C. aquatica in other morphological characters (C. aquatica has flowers with three sepals and three petals) and since variation in number of floral parts is common in the genus, Ørgaard synonymized both species. After an analysis of C. schwartzii type material, other herbarium collections and location of four populations (two with C. schwartzii characteristics and two with C. aquatica characteristics), we conducted an integrated morphological and genetic study to evaluate whether or not C. schwartzii is a distinct species from C. aquatica. The results reveal the species to be distinct from each other and therefore C. schwartzii should be reestablished. The floral formula for C. schwartzii is K2 C2 A2+2 G1, versus K3 C3 A3+3 G2 for C. aquatica. A detailed species description and the geographical distribution of C. schwartzii are presented with a dichotomous key to distinguish both species, together with illustrations.

The Great War

The main aim of the conducted research was to determine the presence of allochthonous plants in the area of the protected natural reserve - The Great War Island. The research was conducted during the vegetation season of 2020. Thirty four allochthonous plant species were recorded and classified into 19 families. Asteraceae (8 species), Fabaceae Poaceae and Sapindaceae (3 species each) had the highest species diversity. Phytogeographic analysis of their primary distribution areas has shown that most belong to the category of floral elements of the "adventitious" areal type. The chorological spectrum is dominated by species of North American origin (58.8%), while in the biological spectrum the most common are therophytes (38.2%). Chronological spectrum analysis has shown the highest prevalence of neophytes (64.7%). Seventeen species have the status of invasive, 16 naturalized, while one species (Morus alba) is characterized as ephemerophyte. The most frequent neophytes on the Great War Island are Acer negundo, Ailanthus altissima, Amorpha fruticosa, Fraxinus pennsylvanica, while among neotophytes, Echinocystis lobata and Symphyotrichum lanceolatus stand out in terms of frequency of occurrence. The geographical position of the Great War Island, due to which it is exposed to periodic floods, high levels of groundwater, strong influence of anthropogenic factors and the biological characteristics of allochthonous species are the main factors enabling them to inhabit this area. Results of this research should be the basis for the development of a strategy for monitoring the condition and planning control measures for the unwanted plant species, in order to protect the indigenous flora. Only careful and responsible management of landscapes of outstanding features such as The Great War Island and taking appropriate preventive measures can prevent the settlement, domestification and further spread of allochthonous plants.
