Based on route and sample-plot survey, plant resources of Liangzi Lake Wetland Nature Reserve were investigated. The result showed that there were 503 species of spermatophyte belonging to 296 genera of 86 families. There were 5 species under national first and second level protection. The dominant families of spermatophyte contained 20 species and above. The dominant genera of spermatophyte contained 4 species and below. The 86 families of spermatophyte can be divided into 7 distribution types and 4 variants. Tropic distribution type was dominant, accounting for 70.83% in total (excluding cosmopolitans). The 296 genera of spermatophyte can be divided into 14 distribution types and 9 variants. Temperate elements were a little more than tropical elements, accounting for 50.84% and 49.16% in total (excluding cosmopolitans) respectively. Reserve had 3 Chinese endemic genera, reflecting certain ancient and relict. The purpose of the research is to provide background information and scientific basis for the protection, construction, management and rational utilization of plant resources in the reserve.

Annotation:

The Midlands region of KwaZulu-Natal (KZN) Province in South Africa was hitherto a putative centre of floristic endemism (CFE) based on conjecture. The aim of this study was to empirically explore this concept by delineating unambiguous boundaries for this CFE and documenting the endemic spermatophytes within a conservation framework. The Greater Midlands Centre of Floristic Endemism (GMCFE), a more expanded study area than the parochial Midlands region of KZN, is formally described as southern Africa’s 20th CFE. It is a mid-elevation region occupying the greater Midlands of KZN, with extensions of contiguous grasslands extending northwards into southern Mpumalanga and southwards into north-eastern Eastern Cape. This “foothills” CFE covers ca. 77,000 km2 of predominantly mesic C4 grassland, ranging in elevation from ca. 700–2200 m a.s.l. It is congruent with the “sub-escarpment ecoregion,” essentially a composite of the Sub-escarpment Grassland and Savanna Bioregions and the sub-escarpment grasslands of southern Mpumalanga and northern KZN. The GMCFE hosts at least 220 endemic spermatophytes, of which almost a fifth belong to the family Apocynaceae. Families Asteraceae, Asphodelaceae, Fabaceae, and Iridaceae also contribute significantly. Genera Ceropegia, Aloe, Dierama, Kniphofia, Helichrysum, and Streptocarpus contribute the most endemics. More than half are forbs, and almost three-quarters are confined to the Grassland Biome. Endemic radiations are attributed to geodiversity and geological complexity (especially the strong lithological influence of dolerite); physiographic heterogeneity (particularly elevation gradients and variable terrain units); strategic proximity to hyper-diverse temperate and subtropical “border floras”; and localized pollinator-driven adaptive radiations. Of alarming concern is the high number of threatened plant taxa, with ca. 60% of the endemic flora Red Listed in threat categories (CE, E, and VU) or considered “rare”. Extremely low levels of formal protection and poor ecological connectivity, coupled with high levels of land transformation and intensive utilization, render the GMCFE one of the most imperilled CFE in South Africa. Urgent conservation action is required to safeguard this unique and highly threatened “rangeland flora” and stem the biodiversity crisis gripping the region.

Annotation:

Macrophytes were studied downstream of the Rophémel hydroelectric dam on the River Rance (Côtes d’Armor Department, western France) to assess the effects of hydroelectric functioning on river macrophyte communities. We studied ten representative sections of the hydro-peaking channel on five occasions in 1995 and 1996, on a 15-km stretch of river. Floristic surveys were carried out on sections 50 m in length, and genera of macroalgae, species of bryophyta, hydrophytes, and emergent rhizophytes were identified. For the aquatic bryophytes and spermatophytes section of our study, we compared our results with 19thcentury floristic surveys, before the dam was built. During the vegetative growth period, the hydro-peaking frequency was low. The plant richness was highest near the dam. The macrophyte communities were highly modified according to the distance to the dam. The frequency and magnitude of hydro-peaking was related to the aquatic macrophyte richness in an Intermediate Disturbance Hypothesis position. However, the results of the eco-historical comparison with 19thcentury floristic surveys point to the original nature of the flora found at the site. Some floral patterns, seen during both periods and at an interval of 133 years, were indicative of the ubiquity of the aquatic flora and of the plants’ adaptability. This demonstrates the importance of taking river basin history into account in such biological surveys.

Annotation:

In the winter of 2014/2015, an impactful natural disaster hit the eastern region of Serbia, leading to substantial forest tree damage due to ice breaks and falls. This catastrophe resulted in the near-complete destruction of artificial conifer stands established on beech sites, and varying degrees of damage to natural stands. In response, approximately 2000 hectares of land had to be clear-cut, inducing significant ecosystem transformations that may have altered the floristic composition. This study involved the inventarisation of vascular flora within the clear-cut areas, which was then compared to the floristic composition at similar site condition on location "Vinatovača" beech primeval forest. The key objectives of this research were to assess the extent of degradation experienced by natural beech sites and explore the prospects and courses for establishing natural, indigenous forest ecosystems through natural succession. Following clear-cutting, beech sites exhibited notably greater floristic diversity in contrast to the natural beech primeval forests. Considerable area of beech sites turned into meadows or were weed covered. The study identified 176 taxa of vascular flora on the clearcut sites (107 taxa in the premival forest). In addition to plants from mesophilic beech communities, plants from the aliance of thermophilic communities are also present. The identified plants were categorised into two groups: Pteridophyta, with only 2 species, and Spermatophyta, encompassing 174 species (in contrast, the premival forest had 10 species of Pteridophyta and 97 species of Spermatophyta). The Spermatophyta plants were further classified into two classes: Dicotyledons, represented by 149 species, and Monocotyledons, represented by 25 species (in the premival forest, Dicotyledons accounted for 76 species, and Monocotyledons 21 species).

O projeto Flora Fanerogâmica do Estado de São Paulo tem se dedicado a inventariar a flora paulistana há quase 20 anos. Conta com a atuação de mais de 200 colaboradores, a maioria do próprio estado, além de pesquisadores de outros estados e do exterior. Desde 2001, foram publicados sete volumes com as monografias de 151 famílias, contendo 3.237 espécies em 722 gêneros. Este projeto foi o ponto de partida para o conhecimento da diversidade das espécies de espermatófitas do estado de São Paulo. A apresentação do checklist neste momento é oportuna por constituir a produção de uma listagem das espécies com identificações certificadas pelos especialistas, além de conter a referência de uma coleção de herbário para a maior parte dos táxons (material-testemunho) ou referência à bibliografia em que a espécie é citada como ocorrente, de forma nativa ou subespontânea, no estado. Dessa forma, é aqui apresentada a listagem das espermatófitas do estado de São Paulo, com 7.305 espécies, distribuídas em 1.776 gêneros e em 197 famílias (segundo Cronquist 1981) ou então 195 (segundo o APG III). Em relação à flora do Brasil, com 31.728 espécies de espermatófitas, o estado São Paulo compartilha de 23% dessas espécies. As famílias mais representativas são Orchidaceae (797 espécies), Asteraceae (676 espécies), Fabaceae (513 espécies), Poaceae (500 espécies), Myrtaceae (304), Rubiaceae (265 espécies) e Melastomataceae (253 espécies) que, juntas, somam 3.308 espécies e constituem mais de 45% do total de espécies de espermatófitas do estado. Considerando a grande diversidade vegetal brasileira, parcialmente expressa em um estado, depreende-se a grande importância da continuidade dos estudos florísticos no Brasil, país provavelmente detentor da maior diversidade vegetal do planeta.

Sukorambi Botanical Garden is a natural tourist spot for flora and fauna with a land area of about 12 hectares. In this location, there are about 500 types of plants ranging from lower-grade plants to higher-grade plants. The existence of seed plants (Spermatophyta) of habitus tree in the Botanical Garden has been identified, but there are some plants whose species are not yet known. This research is a descriptive study with a qualitative approach. The method used in this research is a survey method. The research data were analyzed descriptively and identified to the genus level. The results showed that there were 66 genera of seed plants (Spermatophyta) belonging to 30 families. These families are Achariaceae, Anarcadiacea, Annonaceae, Apocynaceae, Araucariaceae, Arecaceae, Bignoniaceae, Burseraceae, Clusiaceae, Ebenaceae, Fabaceae, Gnetaceae, Lamiaceae, Lauraceae, Lythraceae, Malvaceae, Meliaceae, Mimosaceae, Moraceae, Moringaceae, Myristicaceae, Oxalidaceae, Rutaceae, Sapindaceae, Sapotaceae, and Thymelaeaceae. The results of identification can be used as a learning resource to support the Plant Taxonomy course.

Annotation:

The site of the National Pedagogical University is experiencing a phenomenon of increased anthropization due in particular to academic activities for many years, to the socio-political crisis and to the effects of climate change on the quality of biodiversity. The study focuses on the dynamics of the flora of the National Pedagogical University based on the comparison of two inventories respectively carried out in 2012 and 2022. Factors related to farming methods and those related to climate and soil have an influence on vegetation. Through the analysis of floristic parameters and the dynamics of land use of this site, a negative evolution of the flora emerges. The appreciation of the floristic parameters is based on the interpretation of floristic inventory data. A total of 49 plant species belong exclusively to spermatophytes, distributed among the classes Magnoliopsida (93.9%) and Liliopsida (6.1%). Anthropogenic action has played a role both in the degradation of the site and in the mitigation of climate change.

Annotation:

The classification of the plant family Asteraceae is discussed. The family belongs to the division Spermatophyta (Magnoliophyta), subdivision Angiospermae, class Dicotyledoneae (Magnoliopsida), subclass Asteridae, superorder Asteranae and the order Asterales and is divided into three subfamilies: the Barnadesioideae (not in Flora of southern Africa region), the Cichorioideae and the Asteriodeae. The subfamily Cichorioideae is further divided into eight tribes of which one (Liabeae) does not occur in southern Africa and one genus (Corymbium) is not assigned to a tribe. The subfamily Asteriodeae is divided into 10 tribes. The subfamily Cichorioideae and its tribes are more fully described in this article. The genera belonging to these tribes are listed and their distribution given.

Annotation:

Floral initiation is a major phase change in the spermatophyte, where developmental programs switch from vegetative growth to reproductive growth. It is a key phase of flowering in tea-oil trees that can affect flowering time and yield, but very little is known about the molecular mechanism of floral initiation in tea-oil trees. A 12-year-old Camellia oleifera (cultivar ‘changlin53’) was the source of experimental materials in the current study. Scanning electron microscopy was used to identify the key stage of floral initiation, and transcriptome analysis was used to reveal the transcriptional regulatory network in old leaves involved in floral initiation. We mined 5 DEGs related to energy and 55 DEGs related to plant hormone signal transduction, and we found floral initiation induction required a high level of energy metabolism, and the phytohormones signals in the old leaves regulate floral initiation, which occurred at stage I and II. Twenty-seven rhythm-related DEGs and 107 genes associated with flowering were also identified, and the circadian rhythm interacted with photoperiod pathways to induce floral initiation. Unigene0017292 (PSEUDO-RESPONSE REGULATOR), Unigene0046809 (LATE ELONGATED HYPOCOTYL), Unigene0009932 (GIGANTEA), Unigene0001842 (CONSTANS), and Unigene0084708 (FLOWER LOCUS T) were the key genes in the circadian rhythm-photoperiod regulatory network. In conjunction with morphological observations and transcriptomic analysis, we concluded that the induction of floral initiation by old leaves in C. oleifera ‘changlin53’ mainly occurred during stages I and II, floral initiation was completed during stage III, and rhythm–photoperiod interactions may be the source of the main signals in floral initiation induced by old leaves.

Malgré l'intéret qu' on porte de plus en plus aux zones humides á travers le monde, peu d' etudes ont été consacrées á la flore hygrophile marocaine. Aprés avoir prospecté 45 stations, on a évalué la diversité spécifique des hygrophytes du Maroc méditerranéen á partir de 70 relevés floristiques. Sur les 389 espéces reconnues dans cette etude, 175 especes sont caractéristiques des zones humides. Les espéces rares ou nouvellement citées ont été soulignées. D'autre part, les phytocenoses observées ant été classées en fonction de la physionomie et de la composition spécifique. Une attention particuliere a été consacrée á la discussion des principaux facteurs écologiques influant sur les groupements hygrophiles á savoir : la submersion, la salinité, la charge organique domestique, le mésoclimat et les travaux d'aménagement. Ainsi, on a pu regrouper les espéces dominantes en classes écologiques.

Annotation:

The invasive rust Austropuccinia psidii, responsible for myrtle rust disease, poses a serious threat to the New Zealand Myrtaceae. Since the 2017 detection of Austropuccinia psidii in Aotearoa / New Zealand, the rust has spread rapidly, resulting in the decline and death of a range of indigenous Myrtaceae, most notably the two species of the endemic genus Lophomyrtus, ramarama (L. bullata) and rōhutu (L. obcordata). While the threat Austropuccinia psidii poses to Lophomyrtus is now widely recognised, the indirect impact the rust has on the associated biota is poorly understood. Very little has been documented about the biota found in association with Lophomyrtus. To rectify this, we undertook a survey of the specimens held in three of the key Aotearoa / New Zealand herbaria that had been collected from Lophomyrtus. This was supplemented by field work in eight sites in western Te Ika a Maui / North Island, and north-western Te Wai Pounamu / South Island of Aotearoa / New Zealand. Although the herbarium searches located few specimens, and field work was limited to a few sample points within the range of Lophomyrtus, we found 221 taxa associated with Lophomyrtus, 176 taxa on ramarama, 81 on rōhutu and one on the naturally occurring hybrid between these two species Lophomyrtus ×ralphii. Of the 176 taxa found on ramarama, 59 are bryophytes (one hornwort, 33 liverworts and 25 mosses), five pteridophytes, 16 spermatophytes and 96 are lichenised mycobiota. Rōhutu supported 81 taxa: comprising one cyanobacterium, one alga, twenty-nine bryophytes (17 liverworts and 12 mosses), four pteridophytes, two spermatophytes and 44 lichenised mycobiota. Wild populations of Lophomyrtus ×ralphii were not investigated, and herbarium searches only disclosed one plant, the mistletoe Korthalsella lindsayi, associated with it. Several lichens and liverworts collected from Lophomyrtus represent potentially new species, and Lepra erythrella is a new addition to the lichenised mycobiota of Aotearoa / New Zealand. None of the putative new species are endemic to Lophomyrtus.

No ensino, para possibilitar um aprendizado significativo, é necessário utilizar metodologias variadas onde o aluno consiga ser atuante em seu próprio aprendizado. Uma das metodologias de ensino que permitem essa maior autonomia dos estudantes são as aulas de campo. Dessa forma, o objetivo desta pesquisa foi levantar as espécies mais relevantes de cada ambiente visitado durante uma aula de campo da disciplina de Morfologia e Anatomia de Espermatófitas do Curso de Ciências Biológicas (CCB), inserido no Centro de Ciências da Saúde (CCS) da Universidade Estadual do Ceará (UECE). As espécies foram fotografadas e, em seguida, as fotos foram selecionadas e tratadas com o Adobe Photoshop CS6. Os espécimes foram identificados através de literaturas especializadas, consultas a especialistas e sítios de dados online. Registraram-se 57 espécies pertencentes a 50 gêneros e 30 famílias botânicas, onde se observou que a família mais representada foi a Fabaceae (nove espécies), somando aproximadamente 15,8% da flora levantada, e o gênero mais representativo foi Byrsonima sp. (quatro espécies). Constatou-se que a flora prevalece, em geral, de origem nativa (55 espécies) sendo a maioria endêmica. Quanto à forma de vida dos vegetais, observou-se que 43,8% (25 espécies) representam árvores, em geral, das famílias Fabaceae, Malpighiaceae e Myrtaceae. Além disso, os tipos de vegetação predominantes foram Caatinga, Mata Atlântica e Restinga.Palavras-chave: Biomas, diversidade vegetal, flora, inventário.

Annotation:

AbstractThe fern Platycerium bifurcatum is a valuable component of the flora of tropical forests, where degradation of local ecosystems and changes in lighting conditions occur due to the increasing anthropogenic pressure. In ferns, phytochrome mechanism responsible for the response to changes in the value of R/FR differs from the mechanism observed in spermatophytes. This study analyzed the course of ontogenesis of nest leaves in P. bifurcatum at two values of the R/FR ratio, corresponding to shadow conditions (low R/FR) and intense insolation (high R/FR). The work used only non-destructive research analysis, such as measurements of reflectance of radiation from the leaves, their blue-green and red fluorescence, and the chlorophyll a fluorescence kinetics. This allowed tracing the development and aging processes in the same leaves. Nest leaves are characterized by short, intense growth and rapid senescence. The study identified four stages of development of the studied leaves related to morphological and anatomical structure and changing photochemical efficiency of PSII. Under the high R/FR ratio, the rate of ontogenesis of the leaf lamina was much slower than under the low R/FR value. As shown, the rapid aging of the leaves was correlated with faster decline of the chlorophyll content. It was shown that leaf senescence was accompanied by accumulation of polyphenols, anthocyanins and carotenoids on the basis of reflectance and fluorescence measurements in the blue-green range.

The catchment of the River Kokemäenjoki covers ca. 27 100 square kilometers in western Finland, and the the length of the river is ca 120 km. The river discharges into the Bothnian Bay, the northern section of the Baltic Sea. The delta is changing and prograding towards the sea exceptionally rapidly. The pace of the growth of the deltaic formations,a s well as the major zones of the macrophytivc vegetation is nowadays some 30–40 meters a year. This makes the delta the most rapidly changing aquatic and littoral ecosystem in the Northern Europe. The Kokemäenjoki River delta is often characterized as a biological hotspot, and major sections of the estuary are included in several leading international nature conservation programmes, i.e. The Natura 2000 network of the European Union, the intergovernmental The Ramsar Convention on Wetlands, as well as in the IBA, Important Bird Area programme established by the BildLife International organization. The diversities of both flora and fauna are very high – at least as regards of the northern location of the estuary. In the Kokemäenjoki River ca. 420 taxa of flowering plants (Spermatophyta) are permanently found (i.e. about a third of the ca. 1 200 flowering plants permanently growing in Finland). Of the pteridophytes (Pteridophyta), there are 17 out of the 57 species of the Finnish taxa growing at the delta. Of the stoneworts (Chrarophyta) the delta is home of 9 species of the 21 taxa found in Finland. The number of bird species breeding in the area is ca. 110, and the total number of bird taxa living and resting during the migration periods amounts to 220 species (i.e. nearly the whole range of the 248 bird species of the permanent Finnish bird taxa). Of the invertebrates, the species composition of dragonflies (Odonata) is best known. There are 25 species of the 55 dragonfly taxa found in Finland. Of the plant species occupying the delta, 5 species of flowering plants and one species of stoneworts are classified as endangered, fulfilling the red list criteria established by the International Union for Conservation of Nature (IUCN). Of the bird species of the estuary, 31 species are included in the Red List of endangered species. The present paper summarizes the data presented in various reports, mainly in Finnish, and majority of them in hardly accessible depositories.
