New records for the flora of Angola: observations from Uíge and Cuanza Norte

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.

Проведена инвентаризация чужеродных и аборигенных видов растений вдоль Транссибирской магистрали на участке Тельман (Еврейская АО) - Хабаровск (Хабаровский край) - Владивосток (Приморский край) протяженностью 780 км. Исследована растительность 9 железнодорожных станций и участков железной дороги на перегонах, расположенных в трех естественных биомах: Амуро-Уссурийском подтаежном, Зее-Буреинском Приханкайском лесостепном и СихотэАлинском Южном. На каждом участке заложены площадки размером 100 м² в трех различных экотопах: на железнодорожном полотне, на откосах и на подошве железнодорожной насыпи в полосе отчуждения, всего составлено 66 геоботанических описаний. Выявлено 210 видов сосудистых растений: 22 вида древесных растений, 117 поликарпических и 71 вид монокарпических травянистых растений. Чужеродные для флоры Дальнего Востока виды составляют 35% найденных сосудистых растений, 11 из них входят в список самых опасных инвазионных видов России (ТОП-100). Наименее представлена группа древесных растений (10%), наиболее часто встречаются три дерева - инвазионный Acer negundo и аборигенные Salix nipponica и Ulmus pumila. Доля чужеродных видов минимальна в группе древесных растений - 18%. Максимальна доля чужеродных видов среди монокарпических трав (37 видов, 52%), причем большинство монокарпиков (28 видов) являются инвазионными.Наибольшее число видов (162, 77%) отмечено в Амуро-Уссурийском подтаежном биоме, 98 видов (47%) зарегистрировано в Зее-Буреинском Приханкайском лесостепном биоме и 72 вида (34%) - в Сихотэ- Алинском Южном биоме. Число видов коррелирует с природно- климатическими и флористическими характеристиками биомов; по снижению силы корреляции показатели располагаются в ряду: средняя температура → число видов сосудистых растений на 100 км² → среднегодовое количество осадков → общее число видов сосудистых растений. Наименее значимая корреляция с изученными характеристиками отмечена в группе монокарпических трав. Коэффициент сходства флор различных биомов сравнительно низок (Ks ≤ 45%), общими для всех трех биомов являются только 29 видов, причем 18 из них - чужеродные. Самое низкое сходство наблюдается между фитоценозами в полосе отчуждения: это демонстрирует сильное влияние естественной растительности на формирование «железнодорожной» флоры. An inventory of alien and native plant species along the Far East segment of Trans-Siberian Railway was carried out. The studied segment (780 km) runs from Telman station (Jewish Autonomous Region) through Khabarovsk (Khabarovsk Territory) to Vladivostok (Primorsky Territory). Vegetation was studied in three types of natural biomes - Amur-Ussuri Sub-Taiga biome, Zee-Bureya Prikhanka forest-steppe biome, and Sikhote Alin South biome. A total 66 releves were made. 210 species of vascular plants were identified: 22 woody, 117 polycarpic herbs and 71 monocarpic herbs. Alien species for the Far East account for 35% of the vascular plants found, 11 of which are included on the list of the most dangerous invasive species of Russia (Top 100). Woody species are the group that’s least represented (10%), and 3 trees are the most often recorded: invasive Acer negundo, native Salix nipponica and native Ulmus pumila. The maximum fraction of alien species is noted among monocarpic herbs (37 species, 52%), and the majority of these monocarpics (28 species) are invasive. The highest number of species (162, 77%) was recorded in the Amur-Ussuri Sub-Taiga biome. In the Zee-Bureya Prikhanka forest-steppe biome 98 species (47%) were recorded, and 72 species (34%) were recorded in the Sikhote Alin South biome. The number of species correlates with biomes’ natural-climatic and floristic characteristics; in terms of decreasing the force of correlation, the indicators are arranged in the following series: average temperature → number of vascular plant species per 100 km² → average annual precipitation → total number of vascular plant species in the biom. The group of monocarpic herbs has the lowest correlation with the studied factors. The similarity (Sørensen) of the species pool of different biomes is relatively low (Ks ≤ 45%); only 29 species are uniform to all three biomes, and 18 of them are alien ones. The lowest similarity was observed between the plant communities in the railway right of way: this demonstrates the significant influence of natural vegetation on forming the "railway" flora.

Data Deficient

Brazil is one of the most biodiverse countries in the world, with about 37,000 species of land plants. Part of this biodiversity is within protected areas. The development of online databases in the last years greatly improved the available biodiversity data. However, the existing databases do not provide information about the protected areas in which individual plant species occur. The lack of such information is a crucial gap for conservation actions. This study aimed to show how the information captured from online databases, cleaned by a protocol and verified by taxonomists allowed us to obtain a comprehensive list of the vascular plant species from the "Parque Nacional do Itatiaia", the first national park founded in Brazil. All existing records in the online database JABOT (15,100 vouchers) were downloaded, resulting in 11,783 vouchers identified at the species level. Overall, we documented 2,316 species belonging to 176 families and 837 genera of vascular plants in the "Parque Nacional do Itatiaia". Considering the whole vascular flora, 2,238 species are native and 78 are non-native. The "Parque Nacional do Itatiaia" houses 13% of the angiosperm and 37% of the fern species known from the Brazilian Atlantic Forest. Amongst these species, 82 have been cited as threatened, following IUCN categories (CR, EN or VU), seven are data deficient (DD) and 15 have been classified as a conservation priority, because they are only known from a single specimen collected before 1969.

The Central Siberian Botanical Garden of the Siberian Branch of the Russian Academy of Sciences (CSBG SB RAS) is the largest botanical institution in the Asian part of Russia. Founded in 1946, CSBG SB RAS is historically a consortium of two herbarium collections with their own acronyms (NS and NSK) and registration in the Index Herbariorum (Thiers 2020). At present the NS+NSK collections contain about 800,000 herbarium specimens comprising vascular plants (680,000), mosses (25,000), lichens (80,000) and fungi (15,000) gathered, not only in Siberia, but also in the European part of Russia and other parts of the Eurasian and American continents. CSBG SB RAS has the third largest collection in Russia after the Komarov Botanical Institute of RAS (LE) and Moscow State University (MW) collections. The dataset consists of 5,384 records of digitised herbarium specimens of vascular plants belonging to 111 families, collected since the 19th century in 54 administrative regions from the European part of Russia and kept in NS+NSK collections. Herbarium specimens were digitised using two special scanners, both ObjectScan 1600, according to international standards, at 600 dpi, with a barcode, 24-colour scale and spatial scale bar and placed into the CSBG SB RAS Digital Herbarium. For each specimen, the species name, locality, collection date, collector, ecology and revision label are recorded. More than 94% of the records have coordinates that fall within the area of European Russia, west of the Ural Mountains. A total of 5,384 records of vascular plant occurrences with 94.8% geolocations in the territory of the European Russia West of the Ural Mountains were entered.

The non-native vascular plants of Murmansk Region (European Russia) are under active investigation towards the compilation of the first complete checklist. This work is part of the project 'Flora of Russian Lapland', which ultimately aims at the complete inventory of the taxonomy, distribution and status of vascular plant species in Murmansk Region, based on the comprehensive database of herbarium specimens, field observations and literature. New territory-level records of non-native vascular plants emerged during our inventory of herbarium collections and recent fieldwork. Fourteen species (Anthemis ruthenica, Aruncus dioicus, Bromus commutatus, Chaerophyllum hirsutum, Galega orientalis, Geum aleppicum, Leonurus quinquelobatus, Lepidium densiflorum, Levisticum officinale, Myrrhis odorata, Phleum phleoides, Prunus armeniaca, Rorippa sylvestris, Senecio vernalis) are reported as new to Murmansk Region. The historical occurrences of alien plants appeared in the territory largely as contaminants (of seed or forage). In particular, Rorippa sylvestris and Senecio vernalis arrived with the forage imported during the Second World War. All recent occurrences originated by escape from confinement (ornamental purposes, horticulture, agriculture), reflecting a high diversity of the modern assortment of cultivated plants in commerce and private gardens. Regarding the invasion status, five alien species are considered casual and eight species are treated as locally established or persisting (for uncertain time). Only one species, Galega orientalis, is considered naturalised and capable of further spreading in the territory, although without invasive potential.

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.

Antarctic Research

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.

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.
