The aim of the study was to conduct an environmental evaluation of 6 selected sections of the improved Mietiułka River, which included an inventory and analysis of the vascular flora associated directly with this watercourse. The results of the study have shown that the flora of the study area is diverse in taxonomic, syntaxonomic and ecological terms, and that it comprises both typical aquatic plants and species characteristic of the habitats surrounding the river. In the flora found in the study sectors, a total of 114 vascular plant species was identified, which come from 42 botanical families, 15 syntaxonomic classes and belong to different ecological groups. Hemicryptophytes, spontaneophytes, species neutral to continentality as well as species included in the phytochorion with boreal elements: Euro-Siberian subelement, were clearly predominant in the species composition of the flora of all the study sectors. The macrophytes commonly found in Poland had the largest proportion. One species with a small number of stands in the country - water dropwort (<i>Oenanthe fistulosa</i>) - as well as two species threatened with extinction, <i>Sagittaria sagittifolia</i> and <i>Hypochoeris glabra</i>, were recorded.

Abstract To investigate the ecosystems on dunes, five typical dunes were selected in the coastal area of the Baltic Sea in southwest Estonia. To study ground vegetation species richness, species composition and horizontal structure, 251 quadrats of 1 m2 in size were established and descriptions of vascular plants, bryophytes and lichen species were provided. Topographical factors, soil horizons, soil pH and electrical conductivity, soil nutrients, soil moisture conditions and light conditions were determined. In total, 42 vascular plant, 43 bryophyte and 48 lichen species were recorded on five dunes. Vascular plant species richness and composition on forested dunes was dependent on the absolute dune height, zone and aspect of the slope, soil nitrogen, potassium and phosphorus content, soil pH and moisture, the cover of the bryophyte-lichen layer and light conditions. Regarding bryophyte and lichen layer species composition, important factors were the aspect of the dune, vascular plant species cover, light conditions, the thickness of the moderately decomposed organic soil horizon, soil pH, electrical conductivity and volumetric water content. Lichen species richness was highest on the slopes of the dunes, while bryophyte species richness was higher at the bottoms and decreased towards the tops of the dunes. Ground vegetation species richness and species’ horizontal and vertical structure on forested dunes were highly dependent on topography-induced differences, aspect, height and zone of the dunes. The most important factors controlling the complex of ground vegetation were light conditions, soil water content, thickness of the moderately decomposed litter layer and soil potassium and calcium content.

Abstract Background: Ethiopia is rich in woodland natural forest although of increasingly subjected to deforestation and forest degradation with extensive expansion of settlement and agricultural practices. In developing countries like Ethiopia forest is one of the vital resources that determine the livelihood of the local communities. Consequently, woodlands’ of the country’s are under heavy pressure by shifting cultivation and charcoal production. Kafta-sheraro national park is newly established woodland area which lacks documented vegetation diversity and human disturbance on the forest. The study was conducted to quantify plant species richness and diversity along altitude; and identify anthropogenic disturbance on vegetation composition and community diversity of the park. Methods: a Systematic sampling method was used to determine species composition, abundance, and diversity. 161 quadrats each (400 m2) lying 200 m far apart for trees and shrubs while sub-plots (1 m2) for herbs and grasses along transects were established over an altitudinal gradient of 539-1111 m.a.s.l. All vascular plant species were collected and brought to National Herbarium, Addis Ababa University for identification.The degree of disturbance data as (low, moderate and heavy) were visually estimated for each plot. Result: a total of 182 plant species: 63 (34.6%) herbs,46 (25.3%) trees, 38 (20.9%) grasses, 18(9.89%) shrubs, 11 climbers (6.04%), and 6 (3.3%) tree ̸ shrub), belonging to 142 genera and 53 families, were identified. Fabaceae was represented by the highest number of species (37 species; 20.3%) followed by Poaceae (36 species; 19.8%) and Asteraceae, 10 species (5.49%). Three plant communities’ types were identified: Acacia mellifera-Balanites aegyptiaca (1); Hyphaene thebaica-Ziziphus spina-christi (2); Combretum hartmannianum-Terminalia brownii-Boswellia papyrifera (3). Species richness was highest in community 1 (mid-altitude: 607-640 m.a.s.l.).The highest Shannon-Wiener diversity index (H`=2.82) for the forest was in community 2 (low altitude: 539-610 m.a.s.l.) while evenness (J=0.72) was highest in community 3 (high altitude: 674-1111 m.a.s.l.) There was a significant correlation between species richness (p=0.024) and altitude per plot while species diversity was non significant (p>0.05) over altitude. Human activities also strongly correlated with species richness and diversity of specific community type. Conclusion: the site has pronounced floristic composition and diversity. Altitudinal difference and the degree of human disturbance determine variation in species composition and richness among communities. Altitude is significantly correlated with species richness of all community types while it is more strongly correlated with community type1.Crop cultivation, illegal fire, and overpopulation of livestock grazing are the main threats in community types 2 and 3. However, this document is a baseline to vegetation information of the park. detailed study on conservation challenges (anthropogenic disturbance) of the park vegetation and prioritize their mitigation measures should be arranged.

Tropical rainforests contain the highest biodiversity in the world and as a habitat for various types of flora and fauna, including elaterid beetles. Elaterid beetles have an important role as ecological bioindicators. The aim of this research was to study the diversity and species composition of elaterid beetle in two different landscape types. Insect sampling was carried out in Jambi Province on two tropical rainforest landscape, i.e. Bukit Duabelas National Park (TNBD) and Harapan Rainforest. Elaterid beetles were collected by canopy fogging method in the morning. Each landscape consists of four core plots and each core plot consist of three as subplot, total subplots observed in both landscape were 24 subplots. A total of 2069 individuals of elaterid beetles were collected, belonging to 6 subfamilies, 23 genera, and 59 morphospecies. The abundance of elaterid beetles was higher in Harapan Rainforest, while species richness was higher in TNBD landscape. Species dominant in two landscape consist to subfamily Agrypninae, belonging to genera <em>Adelocera </em>with morphospecies <em>Adelocera </em>sp.01. The result of this research showed that landscape differences influencing the composition and abundance of elaterid beetles, but it does not influence in species richness of elaterid beetles.</p>

Bach Ma National Park (BMNP) is recognized as an essential biodiversity hotspot in Vietnam because of its diverse topography, high species richness and threatened and endemic species. This study updates the richness and distribution of vascular plant species in the BMNP by intergrading data from literature, field surveys, key-informant interviews and participatory observations. Our results showed that the park has a high diversity of vascular plants with 1,874 species belonging to 192 families, 6 phylums including Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta, Pinophyta, and Magnoliophyta. It also indicates that 199 out of 1,874 vascular species in the BMNP are listed as endangered, precious and rare plant species of Vietnam. In particular, 55 species are part of the IUCN 2020 list, in which 9 are critically endangered species (CR), 15 are endangered species (EN), and 31 are vulnerable species (VU). According to the rankings of the Red List Vietnam (2007), 6 species of CR (accounting for 13.64% compared with the whole country), 36 species of EN (20%), and 52 species of VU (26%) were found in this area. The results provided that vascular plant species are distributed into 2 types based on high altitude (threshold at 900m), but there are no dominant communities. The findings may be essential information for foresters and biologists to recognize and use it as the newest update for their next scientific research in conservation and resource management. Vườn Quốc gia (VQG) Bạch Mã được xem là một điểm nóng đa dạng sinh học quan trọng ở Việt Nam vì địa hình đa dạng, độ phong phú loài cao, đặc biệt là các loài đặc hữu và nguy cấp. Trong nghiên cứu này, chúng tôi đã cập nhật sự phong phú và phân bố của các loài thực vật bậc cao tại VQG Bạch Mã bằng cách kết hợp dữ liệu từ tổng quan tài liệu, khảo sát thực địa, phỏng vấn người am hiểu và điều tra có sự tham gia. Kết quả cho thấy VQG có hệ thực vật bậc cao phong phú với 1.874 loài, thuộc 192 họ, 6 ngành bao gồm Psilotophyta, Lycopodiophyta, Equisetophyta, Polypodiophyta, Pinophyta, Magnoliophyta. Kết quả chỉ ra rằng 199 trong số 1.874 loài thực vật bậc cao tại VQG này được xếp vào danh sách các loài nguy cấp của Việt Nam. Đặc biệt, có 55 loài thuộc danh mục của IUCN năm 2020, trong đó có 9 loài Cực kỳ nguy cấp (CR), 15 loài Nguy cấp (EN) và 31 loài Sẽ nguy cấp (VU). Trong khi đó, theo xếp hạng của Sách Đỏ Việt Nam (2007), nghiên cứu cho thấy có 6 loài CR (chiếm 13,64% so với cả nước), 36 loài EN (20%) và 52 loài VU (26%). Phát hiện của chúng tôi cũng chỉ ra rằng đặc điểm phân bố của các loài thực vật bậc cao ở VQG Bạch Mã gồm 2 kiểu rừng dựa trên độ cao (mức 900m), nhưng không có quần xã nào chiếm ưu thế. Các kết quả này được kỳ vọng sẽ là nguồn thông tin cần thiết cho các nhà hoạt động lâm nghiệp và sinh vật học sử dụng nó như một bản cập nhật mới nhất cho các nghiên cứu khoa học tiếp theo trong bảo tồn và quản lý tài nguyên.

The species richness, number of plants, biomass, and species composition of holo- and hemi-epiphytes were recorded in fifty-six 0.04-ha plots, distributed over forest fallows of 2–30 y old and mature forests in lowland Amazonia (Amacayacu National Park, Colombia). A total of 9190 epiphytic plants representing 162 species were recorded on 4277 phorophytes. Seventy species were classified as holo-epiphyte and 85 as hemi-epiphyte. Aroids were most diverse (58 species) and represented 76% of the total recorded biomass. Anemochory was more dominant among holo-epiphytes and zoochory among hemi-epiphytes. The species richness, density and biomass of both holo- and hemi-epiphytes increased significantly from young fallows to old fallows and mature forests. Hemi-epiphytes had greater density and biomass than holo-epiphytes. In canonical ordination, forest age did not relate to the species composition of holo-epiphytes. However, for hemi-epiphytes, the age effect was significant, suggesting that species turnover takes place in the ageing fallows.

Clear Cutting

Effects of clear-cutting on the ectomycorrhizal (EM) fungus community in a Pinus contorta Dougl. ex Loud. forest near Yellowstone National Park, Wyoming, U.S.A., were assessed using molecular techniques. Samples were taken by soil core in both undisturbed and clear-cut sites by randomized block design. Species overlap was compared between clear-cut and undisturbed sites and ascomycete-basidiomycete ratio was determined, using PCR-RFLP methods. Fifty species of EM fungi were detected in the clear-cut sites, the most common being Cenococcum geophilum Fr., Suillus sp., a member of the suilloid group, a Russulaceae species, and a Thelephoraceae species. Sixty-six species were detected in the undisturbed sites, which were dominated by a Suilloid species, a Tricholomataceae species, Cortinarius sp., and Cenococcum geophilum. Species composition in the clear-cut sites differed significantly from that in the undisturbed sites (P = 0.0001). However, 9 of the 14 species most commonly found in the clear-cut sites were also found in the undisturbed sites, but in much lower abundance, while species rank curves of both stand types mirrored each other. There were no significant differences in species richness, root-tip abundance, or ascomycete-basidiomycete ratio between the clear-cut and undisturbed sites. However, species richness was lower in the clear-cut sites than in the undisturbed sites. An overall loss of species richness after clear-cutting and significant changes in species composition indicate that clear-cutting can negatively alter the EM fungal community, and this may have profound effects on ecosystem function.Key words: ectomycorrhizae, community structure, clear-cutting, molecular techniques.

The article examines the species composition of macrophytes (higher aquatic plants) and ichthyofauna of Lake Martyshiv (waterbody of the Osokorky floodplain, eco-corridor of Kyiv). The features of the ecological distribution of higher aquatic plants within the lake Martyshiv are analyzed. The macrophytes are represented by typical limnophilous(lacustrine) complexes. The presence of various groups of macrophytes in the lake indicates a low level of anthropogenic load and is not so differentfrom the values characteristic of a surface water filesunder standard conditions. 22 species of higher aquatic plants have been registered. Phragmites australis (Cav.) Trin. ex Steud., Typha angustifolia L. and Typha latifolia Lare the most common swamping indicator species. Among the studied plants, it should be noted Nuphar lutea (L.) Smith which is protected on the territory of Kyiv in accordance with the decision of the Kyiv Council of December 23, 2004 No. 880/2290. In the ichthyofauna of Lake Martyshiv, 30 species of fish that belong to 9 familieswere identified. In the structure of ichthyocenosis, phytophils (50%) and zoobenthophages (50%) were the dominant ecological groups in terms ofthe method of oviposition and the type of nutrition, respectively. According to the habitat in the reservoir, bottomfishand thicket-livingcategories prevailed (43.3 and 33.3%, respectively). Four species were found in the ichthyofauna of the lake (Rhodeus amarus (Bloch, 1782), Cobitis taenia (sl) Linnaeus, 1758, Misgurnus fossilis (Linnaeus, 1758), Aspius aspius Linnaeus, 1758), which are included to the listof Resolution of the 6thBerne Conventionthat wasadopted to create the Emerald Network. In addition, Carassius carassius Linnaeus, 1758, listed in the Red Book of Ukraine, as well as the elmLeuciscus idus Linnaeus, 1758, which was included in the new edition of the Red Book of Ukraine, were discovered.The research results illustrate preliminary data on the current distribution of species and biological diversity of aquatic ecosystems of the Osokorkyfloodplain. The presence of a number of ecological groups of macrophytes creates a number of biotopes that are important for the existence and reproduction of fish. Thepreservation of LakeMartyshiv in a lesstransformed state providesgroundsforthe creation of a landscape reserve of local importance.Key words:Lake Martyshiv, macrophytes, ichthyofauna, biodiversity, environmental transformation, habitat. У статті розглянуто видовий склад макрофітів (вищі водяні рослини) та іхтіофауни оз. Мартишів (водойма Осокорківської заплави, екокоридору м. Києва). Проаналізовано особливості екологічного розподілу вищих водяних рослин у межах оз. Мартишів. Макрофіти представлені типовими лімнофільними (озерними) комплексами. Наявність різних груп макрофітів у межах озера вказує на низький рівень антропогенного навантаження та мало відрізняється від значень, характерних для масиву поверхневих вод у референційних умовах.Відзначено 22 види вищих водяних рослин. Найпоширеніші види-індикатори процесів заболочення: Phragmitesaustralis(Cav.)Trin. exSteud., Typha angustifolia L. та Typha latifolia L. Серед досліджуваних рослин варто виокремити глечики жовті Nuphar lutea(L.) Smith,які натериторії Києва охороняються на підставі рішенняКиївської міської ради від 23.12.2004 року No880/2290.У складі іхтіофауни оз. Мартишів виявлено 30 видів риб, які належали до 9 родин. У структурі іхтіоценозу за домінуючими екологічними групами за способомвідкладання ікри та типом живлення були фітофіли (50%) та зообентофаги (50%) відповідно. За середовищем існування у водоймі домінували риби придонних та заростевих груп (43,3 та 33,3% відповідно). В іхтіофауні озера було виявлено 4 види (Rhodeus amarus (Bloch, 1782), Cobitis taenia (s.l.) Linnaeus, 1758, Misgurnus fossilis (Linnaeus, 1758), AspiusaspiusLinnaeus, 1758.), які включені до списку Резолюції 6 Бернської конвенції, прийнятої для створення Смарагдової мережі. Крім того, був виявлений CarassiuscarassiusLinnaeus, 1758., що включений до Червоної книги України, а також в’язь Leuciscus idus Linnaeus, 1758, якого буде внесено до нового видання Червоної книги України.Результати досліджень ілюструють попередні дані щодо сучасного розподілу видів та біологічного різноманіття водних екосистем Осокорківської заплави. Наявність низки екологічних груп макрофітів створює низку оселищ, важливих для існування та розмноження риб. Збереження оз. Мартишів у мало трансформованому стані дає підстави для створення ландшафтного заказника.Ключові слова:озеро Мартишів, макрофіти, іхтіофауна, біорізноманіття, трансформація середовища, середовище існування.

Abstract. Ekasari I, Sadono R, Marsono D, Witono JR. 2021. Species composition and richness of viable seed bank after fire events in Mount Ciremai National Park and Kuningan Botanic Gardens, West Java, Indonesia. Biodiversitas 22: 3437-3447. Forest fire is an environmental disaster that can decline ecosystem function and restoration efforts must be considered to restore forest ecosystems after fire events. Natural regeneration using existing soil seed banks is a promising approach in restoration due to its advantage in terms of minimizing cost. This study aimed to examine the species composition and richness of germinable seed banks in several post-fire sites in Mount Ciremai National Park (MNCP) and Kuningan Botanic Gardens (KGB), West Java, Indonesia. One hundred fifty-eight soil samples were collected from the study sites representing fire events (i.e., four post-fire sites and one non-fire site), and soil depths (i.e., upper, middle, and lower). The collection of soil samples and identification of seedlings emergence were conducted from September 2019 to February 2020. Data were analyzed using ANOVA and correspondence analysis using SPSS Version 22. In total, 4626 emergence seedlings were recorded, belonging to 158 species and 58 families in which 41 families in the upper soil layer, 35 families in the middle soil layer, and 33 families in the lower soil layer. The results showed that Poaceae, Asteraceae, and Euphorbiaceae as the most dominant families. The upper soil layer of post-fire site 2018 had the highest species richness (R=11.98), while the lower soil layer of post-fire site 2012 had the lowest species richness (R=2.64). Our findings suggest that when carrying out restoration activities in post-fire areas, it is preferable to use native species that do not compete with species persisted in soil seed banks.
