Abstract:

The biological spectrum of Chandur, a tropical dry deciduous forest of Arambagh range under Howrah Forest Division, West Bengal, reveals that per hundred species of its flora no less than 46.20 are phanerophytes, 20 chamaephytes, 8.97 hemicryptophytes, 4.83 cryptophytes and 20 therophytes. These involve 143 species of angiosperms and one species each of pteridophyte and angiosperm. The phanero-chamaephytic phytoclimate with dominance of phanerophytes indicates adequate protective measures in vogue while the relatively higher value of chamaephytes reflects the care taken to maintain their existence from adverse factors like grazing and trampling. The decline in the number of hemicryptophytes is a matter of concern given the role they play in eco-restoration, particularly in preventing soil-erosion.

Abstract:

The present study evaluated the floristic diversity and biological spectrum of Muscat Governorate, Sultanate of Oman. Heterogeneity of geology, topography and climatic conditions create a diverse array of habitats across the 3,500 km2 study area, supporting a range of vegetation types. Floristic studies were conducted across 42 sites spread across various habitats such as sand dunes, alluvial plains, gravel plains, wadis, saline dunes, coastal areas, farms and plantations. A total of 264 species belonging to 183 genera and 54 families of angiosperm were documented during sampling the vegetation from different wilayats of the Governorate. Maximum number of species belonged to family Fabaceae (14%), followed by Poaceae (12%), Asteraceae (9%), Apocyanaceae and Convolvulaceae (3.66% each), Boraginaceae, Euphorbiaceae, Zygophylaceae (3% each). The biological spectrum was represented almost equally by therophytes and chamaephytes (30% each), followed by phanerophytes (19%), hemicryptophytes (13%), geophytes (4%), liana (3%), and helophytes (1%). The dominance of therophytes and chamaephytes reveals a thero-chamaephytic phytoclimate for the area. Different habitats are characterized by specific plant assemblages, but some species such as Acacia tortilis, Prosopis cineraria, Tetraena quaterense, Dipterygium gluacum, Aerva javanica, due to their broad ecological tolerance and adaptations, inhabit more than one habitats, while some species are just confined to certain parts of a single habitat.

Abstract:

The Bogdkhan mountain of Mongolia is strictly protected and possesses a unique ecosystem, because of its location in the transitional zone of Siberian taiga and the Asian steppe. Floristic composition and the biological spectrum of the Bogdkhan Mountain were studied during July 2019 to September 2020. A total of 522 vascular plants were recorded belonging to 249 genera and 63 families. Asteraceae was found to be the most dominant family (13.22%; 33 genera and 69 taxa) followed by Poaceae (8.43%; 21 genera and 44). The classified life-form spectra of all the species recorded from the study area revealed the predominance of hemicryptophytes (63.03%) followed by geophytes (11.30%), therophytes (10.34%), phanerophytes (9.58%), chamaephytes (5.36%), and hydrophytes (0.38%). The notable changes found in the biological spectrum, which are chamaephytes from 12 to 5.36%, geophytes from 8 to 11.30% and therophytes from 8 to 10.34%. Variaty of reasons might cause change the life form, such as climate change, anthropogenic impacts, etc. Hemicryptophytes and chamaephytes dominate the flora of the mountain due to the cold mountain niche. The floristic diversity of this mountain tends to decline further videnced from the observed lesser divergence values of geophytes and therophytes. Bangladesh J.

Abstract:

The floristic composition, life form, and chorology were conducted in Al-Madloom mountain, Adhale, South of Yemen. The flora consisted of 159 plant species belonging to 111 genera and 46 families. Apocynaceae (12 genera; 19 species), Euphorbiaceae (eight genera; 14 species), and Acanthaceae (eight genera; 8 species) were the most dominant families in terms of species richness. The plants were classified into different life forms and Chorotypes after standard methods. Among the life forms, Chamaephytes 60 species (37.73%) were the dominant followed by Therophytes 47 species (29.55%), Phanerophytes 29 species (18.23%), Geophytes 15 species (9.43%), Hemicryptophytes six species (3.77%), while two species were Parasites (1.25%). From the Chorological point of view, the study revealed that the highest number of species 56 (35.22%) was recorded in the Su-Za Chorotype, followed by Cosmopolitan 20 species (12.57%), Endemic 18 species (11.32%) and ZU-ZA+SA-SI 16 species (10.06%). The Sudano-Zambenzian constitute 56 species, which means the flora of the study area belongs to the Sudanian region. The domination of Chamaephytes and Therophytes indicates that the investigated area is under deep biotic stress. Endemism in the study area is relatively significant, represented by 11.32% of the total flora collected from the study area, and these taxa were listed to be globally endangered.

Abstract:

Life-forms and biological spectrum of the flora of a riverine forest of Song river have been determined. The biological spectrum reveals that the vegetation of this area is thero-phanerophytic. The life-forms observed were therophytes (52.79%), phanerophytes (29.33%), chamaephytes (7.33%), cryptophytes (5.87%) and hemicryptophytes (4.68%). Results show that the percentage of the therophytes in the riverine area is nearly four times higher than those of the same life forms in the normal biological spectrum of Raunkiaers. The higher percentage of therophytes was due to the biotic disturbances like mining, grazing, browsing and lopping of trees.

The results of a phenology study of 78 species of perennial plants from biomorphological groups of chamaephytes, hemicryptophytes and geophytes over a 20-year period (1996—2015) are discussed. Against the background of air temperature and precipitation changes of the warm season in Novosibirsk, the timing shift in phenological events have been analyzed using calculated linear trends. It is found that the trends for species groups are multidirectional and vary significantly in magnitude. At the same time, most of the shifts in phenology are due not to trends, but to the interannual variability of climatic indicators.

Abstract:

Abstract. The Mediterranean basin is a strong candidate for monitoring climate change successfully, a priority of UN SDG 13, because of its long settlement history. Human-environmental contact has typically hindered monitoring efforts because the natural indicators that enable dependable monitoring have been altered anthropogenically. This research describes a two-step process which turns that synanthropism into an advantage through geoarchaeology, remote sensing, GIS, meteorology, and floristic classification. First, archaeological survey data were employed in a semi-arid region of Israel to identify areas of more and less intensive land-use over 2300 years. Trend surfaces were derived in GIS from ancient periods of most intense monoculture agriculture (Hellenistic, Byzantine, and Ottoman). 2020 land-cover was classified using VENμS satellite wet / dry season NDVI imagery and an airborne LiDAR canopy height model. This was reclassed after fieldwork to three broad land-cover classes and cross-tabulated with the 2300-year land-use intensity model in GIS. The results indicate a land-use legacy whereby woody perennial species are more abundant where land-use was cumulatively less intense. Second, unmanned aerial vehicle surveys were conducted in these areas of less-intense land-use. There, on lightly grazed lands where woody encroachment occurs but chamaephytes regenerate due to the grazing, microplots were established. Phanerophyte and chamaephyte shrubs were identified based on Raunkiaer type and the species associated with chorotype (geographic origin). This was compared with aridity index values derived for the study area between 2010-2022. The study provides a prototype, using dependable phytogeographic indicators, that may be developed into a long-term climate monitoring station (LTCMS).

Abstract:

Atlantic coastal cliff heathlands are chamaephytic vegetation dominated by Ericaceae, most often associated to Fabaceae (Ulex) and integrated from a phytosociological point of view into alliance of Dactylido oceanicae-Ulicion maritimiGéhu 1975 (class of Calluno vulgaris-Ulicetea minoris Braun-Blanq. & Tüxen ex Klika & Hadač 1944). This alliance gathers coastal heathlands under marine influences whose physiognomy is marked by prostrate or halo-anemomorphic chamaephytes. All Atlantic heathlands are included into habitats of European community interest which justify the designation of Natura 2000 sites. Within these protected areas, heathland conservation or restoration management issues raise the question of the choice of nature and frequency of management methods. For that, it seems important to understand the dynamics of cliff-top coastal heathlands. Stable heathlands, considered as permanent vegetation of primary character, can be managed without any intervention, while heathlands characterized by a progressive dynamic may be subject to interventionist management. The aim of this work is to present the main determinant abiotic and biotic factors driving the cliff-top coastal heathlands. Human uses may influence the composition and structure of these vegetation. This approach helps to assess the primary or secondary character of cliff-top coastal heathlands vegetation, their stability or dynamic. This article clarifies the notions of primitive, primary and secondary coastal heathlands. It proposes criteria to differentiate stable heathlands and unstable heathlands which are characterized by a progressive dynamic towards coastal scrublands or forest: abiotic conditions, floristic combination, physiognomy. The synphytosociological methodology is useful for establishing the typology of the series, permaseries and minoriseries, in which the different types of cliff-top coastal heathlands are included.

The synphytosociological methodology is useful for establishing the typology of the series, permaseries and minoriseries, in which the different types of cliff-top coastal heathlands are included.

Abstract:

Our work, is interested in assessing the biodiversity in the Mount of Sidi youcef region of Saida (Western Algeria), for this sixteen stations are selected, within each station, a floristic inventory has been made. The results obtained show that the species richness is 69 species, distributed in 30 botanical families dominated by Caryophylacea Poaceae and Liliaceae. The biological spectrum of these species reveals the dominance of therophytes constituted the bulk of the flora, followed by geophytes, phanerophytes, hemicryptophytes and chamaephytes. PCA statistical processing (principal component analysis) of the floristic analysis of the stations examined reveals the formation of four groups defining a set of stations marked by the presence of certain phytoecological similarity.

Abstract:

As part of this research, we made a dendrometric and ecological characterization of the Atlas pistachio stands located in the Naâma region through a series of dendro-architectural measurements and observations and floristic surveys. These stands are characterized dendrometrically by the presence of a pure stand with a regular structure dominated by very big wood (VBW) with 51,20%. The healthy tree and resilient tree ARCHI type are the most dominant with 65,10% and 23,20% respectively. From an ecological point of view, the stands studied harbor a low floristic diversity, made up of 21 species belonging to 20 genera and 13 botanical families. This low richness which is characterized by the dominance of chamaephytes (47,62%) and therophytes (23,81%) is the result combined of anthropogenic pressure and climatic aridity.

AbstractIn this study, the subalpine vegetation in the Giresun Mountains of northern Turkey was investigated. The study area included north- and south-facing slopes at altitudes ranging betweenc.2000 and 2500 meters. For vegetation classification and for describing the relationships between vegetation and environment, traditional Braun-Blanquet methods and multivariate analysis techniques were used. The vegetation mainly consisted of subalpine grasslands and coniferous cushion scrubs.Caricetea curvulaeandAstragalo microcephali-Brometea tomentelliwere found to be dominant syntaxa in the vegetation of the study area. Land topography, soil physical and chemical factors and species richness have important impacts on the development of subalpine vegetation according to the results of multivariate analysis. Three associations and two subassociations were newly determined and classified. Hemicryptophytes, chamaephytes and geophytes participated in the floristic composition of these syntaxa. EUNIS habitat code and names for described syntaxa were also proposed.

Full text

Abstract:

Lygeum spartum L. (Poaceae) is a perennial native grass grown throughout arid and semi-arid regions around the West Mediterranean basin. In terms of pastoral use, its associations with other annual species and small chamaephytes constitute a valuable source of livestock forage. L. spartum, which has an extensive root system, reduces soil erosion and enhances soil stabilisation. The leaves contain many fibres, producing a material suitable for basket manufacture. This plant species can also be used in the phytoremediation of contaminated soils. Published work on the research and development of this species is meagre. This article represents an effort to compile the literature on L. spartum and to review the current understanding of this plant and its potential as an alternative source of fodder during periods of forage scarcity, for traditional craftsmen, for phytoremediation and for rangeland rehabilitation purposes.

Abstract:

Localities and Sites ofPulsatilla Vernalisin the Julian AlpsApplying the standard Central-European method we phytosociologically studied the sites ofPulsatilla vernalis, a rare and protected species of Slovenian flora, in the frost hollows on mountain pastures Ovčarija and Za Grivo in the Fužina pasturelands (the Triglav mountains, the Julian Alps). We established that it grows in a unique community of swards and heaths which usually extends over small surfaces (4-10 m2) and is dominated by herbaceous perennial species (hemicryptophytes) and dwarf shrubs (chamaephytes) with mostly arcticalpine and south-European montane distribution. This community is explicitly (floristically and ecologically) different from the communities of swards and heaths described in the Julian Alps so far, so we classified it into a new associationPulsatillo vernalis-Dryadetum octopetalaeass. nova (orderRhododendro hirsuti-Ericetalia carneae) and subdivided it into two, floristically and ecologically clearly distinguished subassociations -ericetosum carneaesubass. nova and -vaccinietosumsubass. nova.

Abstract:

Bassi Wildlife Sanctuary is located in the South-Eastern part of Rajasthan, India. This study resulted in plant life form diversity and distribution using Raunkiaer's classification system. Extensive field surveys were conducted in BWS between April 2017 and March 2019 to identify and record plant species. The collected specimens were identified by using state and regional floras (Shetty & Singh, 1987, 1991, 1993; Tiagi and Aery, 2007; Yadav& Meena, 2011; Harikrishna et al., 2022). A total of 468 plant species belonging to 322 genera and 85 families were recorded. The results indicate that therophytes (55.8%) are the dominant life form, followed by phanerophytes (23.5%), hemicryptophytes (7.3%), cryptophytes (6.8 %) and chamaephytes (6.6%). On comparison with Raunkiaer’s normal spectrum, the present study area depicts Thero-phanerophytic type of phytoclimate. This study also provides valuable insights into the plant ecology of BWS and contributes to the understanding of the region's biodiversity.

Full text

Abstract:

Teucrium polium appears in winter as a cluster of short shoots with small leaves (chamaephyte). In early spring, shoots progressively elongate until in late spring shoot elongation ceases. At the tip of each shoot, an inflorescence (dichasium with apical racemes) is developed which completes pollination by the end of July. Summer leaves are about 10-fold larger than winter leaves. In November, summer leaves are shed and the leaf-naked shoots later become dried and abscise. In winter, the dormant buds at the base of the plant break dormancy and generate many short shoots forming a claster. Thymus sibthorpii is also chamaephyte. In early spring, the short winter shoots start increasing in length and by the end of April shoot elongation becomes completed. On the tip of each shoot an inflorescence (raceme) is developed which completes pollination by the end of May. In summer, plants consist of leaf-bearing shoots only (inflorescence axes dry and then drop down). In November, all leaves are shed and small shoots sprout out from dormant buds at the base of the plant.

Abstract:

Natural rangelands occupy about 5.5 million hectares of Tunisia’s landmass, and 38% of this area is in Tataouine governorate. Although efforts towards natural restoration are increasing rapidly as a result of restoration projects, the area of degraded rangelands has continued to expand and the severity of desertification has continued to intensify. Any damage caused by disturbances, such as grazing and recurrent drought, may be masked by a return of favorable rainfall conditions. In this work, conducted during March 2018, we surveyed the botanical composition and species diversity of natural rangelands in Tataouine in southern Tunisia. The flora comprised about 279 species belonging to 58 families, with 54% annuals and 46% perennials. The Asteraceae family had the greatest richness of species, followed by Poaceae, Fabaceae, Amaranthaceae, Brassicaceae, Boraginaceae, Caryophyllaceae, Lamiaceae, Apiaceae, and Cistaceae. Therophytes made the highest contribution, followed by chamaephytes and hemicryptophytes. Of all these species, 40% were palatable to highly palatable and more than 13% are used in both traditional and modern medicine.

Abstract:

Andalusia, together with Morocco, is considered part of one of the two main biodiversity centres existing in the Mediterranean Basin; the other one is in the east and includes part of Turkey and Greece. The Andalusian flora has a fundamental role in this recognition, having been studied since the 1st century A.D. Despite Andalusia having been visited by a myriad of Iberian and foreign botanists, there is still no synthetic work on this subject. In this contribution, we present the first checklist of the Andalusian vascular flora, listing 4437 taxa distributed in 171 families, 1107 genera, 4091 species, and 346 subspecies, of which 3958 are native and 479 alien. Therophytes predominate (1516, 34.2%), followed by hemicryptophytes (1219, 27.5%) and chamaephytes (628, 14.1%). In addition, 462 (10.4%) are endemic or sub-endemic to the territory, and 595 (13.4%) are subject to some degree of threat (135 critically endangered, 137 endangered, and 323 vulnerable).

Vegetation relevés were performed at the single known locality, limestone cliffs facing the sea and revealed a new association, the Thliphthisa sapphus-Lomelosietum dallaportae. The chromosome number of Thliphthisa sapphus was determined as 2n = 4x = 44, being the single tetraploid species in the genus to date. The species also differs markedly morphologically from its morphologically closest relatives, two Greek steno-endemic oreophytes, Th. baenitzii and Th. muscosa by the following characters: densely setose mericarps and corolla, tetraploidy and by its distribution. An identification key for the Greek species of Thliphthisa is provided. Th. sapphus constitutes the westernmost outpost of a group of Greek steno-endemics, highlighting the importance of coastal habitats and their protection as refugia for poorly competitive chamaephytes.

Six families (Aizoaceae, Euphorbiaceae, Papilionaceae, Poaceae, Amaranthaceae and Asclepediaceae) provided nearly half of the total number of species reported. Therophytes and chamaephytes are the most frequent life forms which may indicating a typical desert spectrum vegetation. The floristic composition of the different geomorphologic landscape units offered differences in species richness in the different sectors of the wadi, and the phytochoria. Monoregional and biregional areas contained 45 species (41%), while biregional species were 39 species (36%) respectively, while only two species (2%) were recorded in the pleuriregion. It is thus concluded that the region should be considered a hot-spot in the Kingdom in terms of floral diversity.

Heather is the dominant species in the plant community with beech on these sites (Calluno-Fagetum moesiacae Cvj. 2003). This community is floristically poor and edaphically conditioned. Beech (Fagus sylvatica. subsp. moesiaca (Maly) Czeczott) is the only species in the tree layer, while heather dominates in the ground layer. According to the spectrum of areal types, mesic plant species of middleeuropean distribution type are dominant, with a significant share of plants of the xerothermous submediterranean distribution type. According to the biological spectrum, hemicryptophytes dominate in this community with a significant share of chamaephytes, which indicates deteriorated site conditions. According to the moisture requirements, the community is xeromesophillous, acidophillous according to soil reaction, according to the nitrogen content in soil it is highly oligotrophic, according to the light it is semi-tolerant, and according to the warmth requirement the community is mesothermic. The community of beech and heather represents a degradation stage of beech forests.

Abstract:

Our investigation has documented 400 medicinal plant species belonging to 309 genera and 117 families across five divisions of vascular plants. The life form composition of plants in the study area comprises five groups. The group with the least number of species is the chamaephytes, with 27 species (6.75%), followed by the therophytes with 35 species (8.75%), cryptophytes with 41 species (10.25%), hemicryptophytes with 45 species (11.25%), and the phanerophytes with the highest number of species at 252 (63.00%). The geographical elements have been determined for 390 species (97.50%), while 10 species (2.50%) remain undetermined. In the study area, 18 medicinal plant species (4.5%) have been identified as threatened and in need of conservation. Among these, 15 species (83.33%) require protection according to the Vietnam Red Book; 5 species (27.78%) are listed under Government Decree 06/2019/NĐ-CP; and 5 species (27.78%) are listed in the 2007 Vietnam Red List of Medicinal Plants. Currently, the medicinal plant resources in the study area are being exploited by local inhabitants and are at risk of depletion if conservation policies and measures are not implemented.

Abstract:

Abstract Because of their scarcity, protected areas alone cannot maintain biodiversity. Therefore, it is necessary to create conditions appropriate for plants and wildlife in managed landscapes. We compared the effects of different intensities of forest management on functional responses of vascular understory plants using the fourth-corner method. We analysed functional community composition along a management gradient that spanned semi-natural forests to extensively managed forests (naturally regenerated cuts) to intensively managed forests (planted forests) in Canada. Results showed trait filtering along the gradient of forest management intensity. In natural and extensively managed forests, where forest retention was high in time and space, persistence traits (e.g. perennial geophytes or chamaephytes, non-leafy stem foliage structure) were maintained. At the opposite end of the gradient, in intensively managed plantations where forest retention elements (e.g. amount of dead wood) were reduced, trait filtering led to species associated with colonization, such as tall species with limited lateral extension. These results suggest that intensive forestry conducted over a large extent may change the functional composition of understory plants.

Abstract:

Plant species diversity was studied in 20 sandy wadis of the northern Algerian Sahara (Ghardaïa region). Based on subjective sampling, 20 floristic surveys were carried out in the various sandy biotopes in February-April 2022. Through an ascending hierarchical analysis, we distinguished 3 phytoecological groups and assessed their functional, biogeographic, and abundance characteristics. The recorded plants represented 15 species (296 individuals) belonging to 15 genera of 10 botanical families. The most represented families were the Fabaceae, Anacardiaceae, Brassicaceae, and Poaceae. In terms of the real plant-life spectrum, hemicryptophytes (51.7% of individuals) dominated the sandy wadis, followed by chamaephytes (33.1%) and phanerophytes (15.2%). In the real dispersal spectrum, the barochores prevailed (60%). The real phytogeographic spectrum shows that the Saharan endemic element reached the highest share (32.7%). In terms of abundance, an analysis of the real spectrum revealed that very common species (52%) dominate in the Ghardaïa region, but some fairly rare plants were also found. Indeed, the sandy biotopes of the wadis of the Ghardaïa region are valuable habitats for the conservation of plant species in the northern Algerian Sahara.

Abstract:

This paper enumerates 542 plant species belonging to 289 genera in 89 families of vascular plants collected from Toor Al-Baha district, Lahej governorate, Yemen, during 2008-2015. The Poaceae has the, relatively highest number of species (50 sp., 9.23%) followed by Asteraceae (38 sp., 7.01%), Euphorbiaceae (34 sp., 6.27%), Asclepiadaceae (30 sp., 5.54%), Fabaceae (28 sp., 5.17%) and Acanthaceae (26 sp., 4.80%). A genus represented by the greatest number of species is Euphorbia (19 species). Classification based on life form indicates that the chamaephytes (38.19%) comprise the largest proportion of the plants in the study area, followed by therophytes (28.60%) and phanerophytes (20.85%). The present results revealed that there are three parasitic species belong to two families these are: Cistanche phelypaea and Cistanche rosea (Orobanchaceae) and Striga angustifolia (Scrophulariaceae). Sixty three succulents taxa belong to eighteen families were recorded in the flora of the study area, among these families three are the richest ones (Asclepiadaceae 17, Euphorbiaceae 11 and Aloaceae 6).
