A Critical Discourse Analysis on the Variations of Language Used by Tomboy Characters in Pakistani Dramas

The current study examined the language variations of tomboys' characters in Pakistani dramas to identify the representation of tomboys and the factors that affect their characters by discussing linguistic methods, behaviors of society, stereotypical thinking of society and the role of patriarchy in it. The theoretical underpinning for the current investigation was based on Fairclough's (1989) three-dimensional model for Critical Discourse Analysis. The study employed qualitative research method to investigate the research questions. The data was collected by using a simple random sampling design to collect episodes from two different Pakistani dramas. The tomboys’ characters’ chosen dialogues and the language elements used were divided into three categories based on subjects in the selected episodes. The data was analysed by using the CDA model. leading to conclusions on the role of patriarchy and societal norms in shaping the representation of tomboys in Pakistani dramas. The results of the study showed the negative attitudes of society toward tomboys’ characters. They were often excluded from social groups and activities; discriminated and viewed as less feminine competent. It was concluded that tomboys’ characters could serve as role models for girls who might not conform to traditional gender expectations.

Character variation in separate body regions of Gerreidae (Osteichthyes: Teleostei) fishes inferred from geometric morphometrics.

Body morphology is a valuable feature for distinguishing teleostean fishes. However, the utility of character variation in separate body regions has yet to be tested. The taxonomy of the Gerreidae family is controversial due to character overlapping among its fish species. This work aims to analyze and compare the body shape variation in three regions, cephalic, trunk, and caudal peduncle, using landmark data and geometric morphometric methods in 17 species and five genera of the family Gerreidae. The pattern of shape variation for the cephalic region consisted of well-defined character states exclusive of each species analyzed. Shape variation in the trunk and caudal peduncle regions does not distinguish all species in this study. This study showed that the dorsal cephalic profile is highly variable among the species, therefore, shape variation in this region is useful for distinguishing Gerreidae species. In contrast, some species within the same genus share similar shape states in the trunk and caudal peduncle regions, with the most shape variation in the dorsal profile and anal fin for the trunk and in the middle of the caudal peduncle.

Identification Morphology of Bamboo, and Traditional Use in Gorontalo

Bamboo is a versatile plant that has many benefits in the lives of the people of Gorontalo. This research aims to provide taxonomic information on bamboo species in Gorontalo Province, including variations in morphological characters and phenetic relationships of bamboo, as well as information on the traditional use of bamboo. The method used in this research is exploration and interviews. Exploration was carried out to collect information on bamboo taxonomy, while interviews were conducted to find out the use of bamboo by the Gorontalo Community. The research data obtained was then analyzed descriptively to describe and interpret data on morphological variations, phenetic relationships and traditional benefits of the various types of bamboo obtained. Based on the research results, it was obtained that 13 types of bamboo are distributed in Gorontalo which show the unique morphological variations of the varieties which are divided into four genera, namely the genus Gigantochloa has distinctive morphological characteristics on the waxy surface of the stem, the Bambusa genus with characteristic shiny, smooth stems, the Dendrocalamus genus has the largest diameter and stem wall thickness, the genus Schizostachyum has the same morphological characteristics of stem segments and branch lengths. Based on the analysis of phenetic relationships, two main clusters were formed with a similarity value of 61.2%. In terms of traditional uses, it was recorded in this research that most bamboo is used as building construction materials, food sources, traditional medicine, materials for traditional ceremonies, handicrafts, and ornamental plants, as a tool designedto help people's livelihoods and ecological functions. This research also provides the first record of the morphological characteristics and use of each type of bamboo in Gorontalo which can be used for future bamboo breeding and conservation projects.

Nomenclatural Type Identification of Names in North African Tamarix (Tamaricaceae)

Tamarix is native to Eurasia plus the northern and southern territories of Africa, with some species being introduced into America and Oceania. They are usually found in arid, desertic, or subdesertic areas, often on saline or subsaline soils, in Mediterranean, temperate, or subtropical climates. The genus is renowned for its complex taxonomy, which is usually based on rather variable or unstable characters, which leads to contrasting taxonomic treatments. As part of the taxonomic revision of Tamarix undertaken by the authors, ten names (i.e., T. africana, T. bounopoea, T. brachystylis var. fluminensis, T. malenconiana, T. muluyana, T. tenuifolia, T. tingitana, T. trabutii, T. valdesquamigera, and T. weyleri) published from material collected in the southwestern parts of the Mediterranean basin are taxonomically and nomenclaturally discussed after analysing their original material. Eight intended holotypes are corrected here to lectotypes; one epitype is designated for T. africana to warrant current use of the name; and one isotype, 30 isolectotypes, and 11 syntypes are also identified for the studied names. Further, the taxonomic identity of all names and their eventual synonymic placement are accordingly discussed.

Research on the Variations of Female Characters in Disney Movies Taking the Seven Dwarfs and Moana as Examples

Disney is one of the most famous film companies in the world, and its Disney Princess series is also one of the most popular movies for women and children. The characteristics and personalities of the princesses influence peoples ideas. However, with the passage of time, the image of women in Disney movies has also undergone great changes. In this regard, based on Disneys first princess movie Snow White and the Seven Dwarfs and the last officially certified princess movie Moana, this paper makes a case analysis and comparison of female characters in these two movies. Through the method of literature analysis, it can be concluded that with the development of feminism, Disneys portrayal of female characters has changed from a single, weak and innocent flat image at the beginning to a diversified and independent image of the brave in the modern era.

Molecular Characterization of Colletotrichum gloeosporioides (Glomerella cingulata) Causing Mango Anthracnose Disease

Mango production in Tamil Nadu is known to be adversely affected by C. gloeosporioides in both field and post harvest stage of crop and drastically reduces market and edible value of fruit. To manage the disease it is essential to learn about the nature of pathogen and its way of interaction with host and its survival ability in environment. Hence a study has been carried out on Isolation of fungal pathogen was done using PDA medium in order to identify the disease's causative agent and its variation in morphology and colony characters. A total of twenty-four C. gloeosporioides isolates were obtained from various Tamil Nadu mango cultiavting areas of Tamil Nadu. The isolates were identified morphologically and molecularly. The microscopic features such as conidia shape and size were used to identify C. gloeosporioides. The CTAB technique was employed to extract the DNA from the isolates of C. gloeosporioides. A total of 24 isolates were subjected to ITS (Inter Transcribed Spacer) of 18s ribosomal RNA amplification; all of these isolates exhibited amplified products with a size range of 560 bp, indicating that they were fungal pathogen. The MkCgF and MkCgR PCR primer combination was unique to the ITS region of C. gloeosporioides species. It has been confirmed that all 24 of the C. gloeosporioides isolates are really C. gloeosporioides by amplifying the predicted size of 380 bp.

First southeastern Pacific record of Balloon Alfonsin, Beryx mollis Abe, 1959 (Beryciformes, Berycidae), with notes on geographical meristic variations

Four specimens (151–156 mm in standard length) of Beryx mollis Abe, 1959 were collected from the Nazca Ridge, southeastern Pacific Ocean. These specimens represent the first record of the species from the south-eastern Pacific Ocean and extend the distributional range of the species eastward by ca. 10,000 km from New Caledonia, the previously known eastern limit. Comparison with specimens from other regions reveals geographical variations of some meristic characters in the species.

Genetic Variability Studies in F2 Population of the Wheat Cross DDK-1029 x GPM DIC 66

The selection of breeding material heavily relies on genetic variation and its inherited components. A thorough understanding of genetic variation is necessary in order to develop an improved variety. Thus, genetic parameters were assessed in the F2 population of the cross between DDK-1029 and GPM DIC 66. The genetic variability results indicated a moderate to high phenotypic and genotypic coefficient of variation for characters like days to 50% flowering, plant height, productive tillers per plant, spike length, spikelets per spike, grains per spike, thousand grain weight and grain yield. In contrast, the protein, iron and zinc contents exhibited low to moderate phenotypic and genotypic coefficient of variation. All the traits had higher heritability except for grain yield which exhibited a moderate heritability. All the characters exhibited significant GAM except for days to maturity, iron content and protein content which exhibited moderate GAM. This suggests that high genetic variation, heritability, and GAM for such traits will aid in their improvement through both direct and indirect selection.

Per se performance of elite coconut genotypes and hybrids for economic quality traits and oil yield

The present study was conducted at Coconut Research Station, Aliyarnagar Tamil Nadu state of India. The experimental trees comprised of five tall coconut genotypes viz., IC 610370, IC 610371, IC 610372, IC 610374 and IC 610379 West Coast Tall (Check), and the hybrids viz., Chowghat Orange Dwarf x Aliyar 1 (COD x ALR1), Chowghat Orange Dwarf x West Coast Tall (COD x WCT), Aliyar 1 x Malayan Green Dwarf (ALR1 x MGD), Malayan Green Dwarf x Aliyar 1 (MGD x ALR), Kenthali Dwarf x Aliyar 1 (KTD x ALR1) and Veppankulam Hybrid Coconut VHC 2 (Check hybrid - released from Veppankulam Coconut Research Station, Tamil Nadu Agricultural University, Tamil Nadu, India). Coconut palms of uniform size were taken from the chosen genotypes and hybrids for recording the observation. All the coconut genotypes and hybrids showed variation in yield, nut characters, and quality traits. The results of the present study revealed that the genotype IC 610370 and the hybrid COD x WCT recorded maximum values for all the recorded traits. This was followed by the genotype IC 610371 and the hybrid COD x ALR1.

Echolocation call characterization of insectivorous bats from caves and karst areas in southern Luzon Island, Philippines

Bats are excellent bioindicators and are increasingly used to assess ecosystem health and monitor changes in the environment. Due to increased awareness of the potential transmission of pathogens from bats to humans and recognizing the limitations of traditional bat sampling methods, the use of of non-invasive sampling techniques such as bat recorders were recommended for field-based monitoring studies. In the Philippines, however, bat bioacoustics is still a growing field, and the scarcity of acoustic data hinders the use of echolocation calls to conduct accurate inventories and population monitoring of echolocating bats. Here, we recorded and characterized echolocation calls of insectivorous bats from caves and karst areas located in southern Luzon Island, Philippines. In addition, we compared our results with other studies performed within and outside the country to identify possible regional and local variation in acoustic characters for some species. A total of 441 echolocation calls were recorded from six bat families: Hipposideridae (five species), Rhinolophidae (five species), Vespertilionidae (three species), Miniopteridae (two species), Megadermatidae (one species), and Emballonuridae (one species). Discriminant function analyses (DFA) with leave-one-out cross validation correctly classified bats emitting calls dominated with a constant frequency (CF) component (rhinolophids and hipposiderids) with >97% success and those producing frequency modulated (FM) calls (Miniopteridae and Vespertilionidae) with 88.9% success. We report echolocation calls for Philippine population of two species (Megaderma spasma and Hipposideros lekaguli) for the first time. Moreover, we present geographical variations in call frequencies for some species by comparing previously reported acoustic data elsewhere across the species’ range. This underscores the importance of establishing a readily accessible and comprehensive local reference library of echolocation calls which would serve as a valuable resource for examining taxonomic identities of echolocating bats, particularly those whose calls exhibit biogeographic variations.

Ninth Variation of Classical Group Characters of Type A-D and Littlewood Identities

We introduce certain generalisations of the characters of the classical Lie groups, extending the recently defined factorial characters of Foley and King. In this extension, the factorial powers are replaced with an arbitrary sequence of polynomials, as in Sergeev–Veselov's generalised Schur functions and Okada's generalised Schur P- and Q-functions. We also offer a similar generalisation for the rational Schur functions. We derive Littlewood-type identities for our generalisations. These identities allow us to give new (unflagged) Jacobi–Trudi identities for the Foley–King factorial characters and for rational versions of the factorial Schur functions. We also propose an extension of the original Macdonald's ninth variation of Schur functions to the case of symplectic and orthogonal characters, which helps us prove Nägelsbach–Kostka identities.

Characterization of Isolates of Beauveria bassiana (Balsamo) Vuillemin Collected from Three States of Southwest Nigeria

Beauveria bassiaana is a soil borne fungus with variations in molecular composition across varying locations. Ten isolates of B. bassiaana isolated from soil samples collected from forest sites in three States of Southwest Nigeria were characterized using morphological and molecular tools. The morphological characteristics considered were radial growth, colour of colonies, texture, shape of the spores and filaments and the relationship of the spores to the filaments.Means were separated using Duncan’s Multiple Range Test at 0.05% level of significance. DNA was extracted from the isolates and results from the OTU clustering were sequenced using ITS1 and IT4 primers. Results showed slight variation in colour of the colonies, varying from whitish cream to white, having smooth, powdery textures with colonies becoming more identical as plates extended with no significant differences in texture and elevation of the colonies. The radial growth of the isolates was fast, with complete plate cover of the 9 cm Petri dish plates within 7 days for all the isolates. Images of the conidia as viewed under the microscope at x10 and x100 magnifications were observed to possess conidiophores that have whorl and dense clusters of symphodial, short and globose conidiogenous cells with apical zigzag appearance and one celled spherical conidia that prevents any variation in colonies. Isolate sequences showed a 100% homology to B. bassiana having molecular character variations with isolates 6, 4, 9, 3, 2 having percentage similarity of 99.86 with B. bassiana with accession no BbN06B02, isolate 5 had a percentage similarity of 90.62 with B. bassianawith accession number MW633220.198-48 and isolates 7 and 8 had a percentage similarity of 99.18 with B. bassiana with accession number AY805547.1:180-346 as represented in the dendrogramic tree. These observed variations could be utilized in biological insect pest management.

Agromorphological traits and bioactive compounds of four Mexican chili peppers (Capsicum annuum var. annuum L.)

In Mexico, diverse morphotypes of chili pepper with local recognition are distributed regionally contributing to the in-situ conservation of Capsicum diversity in the hands of farmers, as is the case of Huacle pepper in Oaxaca. The objective of this study was to evaluate the variation among morphotypes of Huacle, Guajillo, Ancho and Pasilla chili peppers, based on agromorphological traits, bioactive compounds and antioxidant activity in fruits. The morphotypes were established in greenhouse conditions under a random block design, obtaining fruit at physiological maturity for laboratory analysis. Significant differences (P ≤ 0.01) were determined in the analysis of variance among and within morphotypes for all the agromorphological characters evaluated, except in plant height at 120 days after transplantating (dat) and specific weight. Different growth patterns were evaluated from 30 to 120 dat, but the final height was similar. Size, weight, shape, pericarp thickness, locules, number and total weight of fruits per plant were used to determine the variation among and within morphotypes. Morphotypes of Huacle (CH-4, CH-9 and CH-15) and Ancho (AN-R) presented the highest values of fruits, total weight and a low number of fruits per plant. Among morphotypes, significant differences (P ≤ 0.01) were observed for fruit composition, but not for antioxidant activity. Also, significant differences were seen in vitamin C, flavonoids content, and antioxidant activity. In fruit composition, Huacle and Guajillo peppers presented a higher vitamin C content (4.5 mg acetic acid g-1). Huacle pepper was also high in total polyphenols (31.5 mg GAE g-1). Ancho pepper showed a higher content of carotenoids (2.8 mg β -carotene g-1) and total flavonoids (3.3 mg QE g-1). Pasilla pepper showed low values in all the evaluated compounds. In conclusion, all morphotypes showed variation in fruit characters (weight, length, width, pericarp thickness, number of locules and fruit length/width ratio). In fruit composition, the variation was in vitamin C, carotenoids, flavonoids and polyphenols, but not in antioxidant activity. Key words: Morphotypes, Huacle pepper, Ancho pepper, Guajillo peppers, fruit composition, phenolic compounds, vitamin C, antioxidant activity

Redescription of the hispidoberycid, Hispidoberyxambagiosus Kotlyar, 1981 from Taiwan, with comments on its morphology (Beryciformes, Stephanoberycoidei, Hispidoberycidae).

A rare spiny-scale pricklefish, Hispidoberyxambagiosus Kotlyar, 1981, is redescribed based on four specimens collected from Taiwan. Their sampling locality represents the northernmost record of the family, which extends the family's distribution from the eastern Indian Ocean and the South China Sea to northeastern Taiwan in the northwestern Pacific Ocean. A detailed description of these specimens and the first description of its sagittal otoliths are provided. In addition, the specimens are compared with other known specimens. Intraspecific variation of some morphological characters are discussed.

Genetic variation and correlations for some physiological characters and seed yield in Indian mustard (Brassica juncea L.) under rainfed conditions

An experiment was conducted with 42 Indian mustard genotypes in Randomized Complete Block design to estimate genetic parameters and correlations of some physiological characters and seed yield under rainfed conditions. Specific leaf area, transpiration rate and relative water content were recorded at 30 (vegetative stage), 45-50 (50% flowering stage) and 60-65 days aftersowing (full flowering stage). Total drymatter, harvest index, pod intensity, pod area on main and primary branches, seed : husk ratio and seed yield were recorded at the time of harvest. The analysis of variance indicated highly significant differences among the genotypes for all the characters studied. The maximum phenotypic and genotypic variability was observed for transpiration rate at full flowering stage. Heritability estimates in broad-sense were high for all the characters except relative water contents (RWC) at all the 3 stages, pod area of main and primary branches and pod intensity on main shoot. High heritability combined with high genetic advance was observed for specific leaf area at all the 3 stages, transpiration rate at 50%and fullflowering and total drymatter/plant suggested scope for selection for these characters owing to predominance of additive effects in the expression of these characters. Seed yield/plant had significant and positive correlations with harvest index (r = 0.581**), total drymatter/plant (r = 0.869**), pod intensity on main shoot (r = 0.467**), pod area of main (r = 0.536**) and primary branches ((r = 0.317*) and RWC at all the 3 developmental stages. Thus, selection for high harvest index, total dry matter/plant and pod intensity coupled with low transpiration rate at flowering stage, resulting in maintenance of high RWC in leaves, should be emphasized to increase yield under rainfed conditions.

Micro-endemism pattern and Wolbachia infection of Quedius obliqueseriatus (Coleoptera, Staphylinidae), a montane rove beetle endemic of the North-Western Caucasus

We conducted an integrative taxonomic study of a forest floor dwelling montane rove beetle Quedius obliqueseriatus Eppelsheim, 1889. It is one of many endemic species of the North-Western Caucasus, a region considered a global biodiversity hotspot. Examination of the morphological characters in 93 specimens of Q. obliqueseriatus and phylogenetic assessment of the COI barcode for 28 of them, revealed that this species in fact consists of two distinct (p-distance of 4.0%) allopatric lineages, western and eastern. They subtly differ in the structure of the aedeagus, which was not noticed in the previous revision of this species. Nuclear DNA markers (H3, ITS1, ITS2, Wg and 28S) sampled in both lineages, did not show any divergence. Variation of the non-genitalic morphological characters, such as body size or coloration, is continuous across both lineages. Discovery of microendemic lineages within an endemic rove beetle species highlights how little is understood about the patterns and drivers of endemism in arthropods of the North-Western Caucasus. We refrained from the description of a new species due to shortage of data from the area where newly discovered western and eastern lineages meet. As Q. obliqueseriatus was found to be largely infected with Wolbachia, we gave a review of this infection among insects and other arthropods and its impact on speciation. Finally, we described our method of removal of the WolbachiaCOI amplicon by endonuclease restriction enzyme in order to get the desired beetle amplicon from infected specimens.

Distribution and morphological variation of tree ferns (Cyatheaceae) along an elevation gradient.

Knowing how species and communities respond to environmental change is fundamental in the context of climate change. The search for patterns of abundance and phenotypic variation along altitudinal gradients can provide evidence on adaptive limits. We evaluated the species abundance and the variation in morphometric and stomatal characters in five tree ferns species (Cyathea fulva, C. divergens, C. myosuroides, Alsophila firma and Gymnosphaera salvinii) distributed along an elevation gradient in a well-preserved Mexican cloud forest. Variation at the community and species level was assessed using exploratory and multivariate data analysis methods. We wanted to explore if the species abundance is environmentally determined, to determine the degree of variation along the elevation gradient, to test for differences between zones and associations with elevation, humidity and soil nutrients, and to assess contribution of the intra- and interspecific variation to the community response to elevation and soil nutrients. The studied fern community showed strong species turnover along the elevation gradient, with some influence of soil nutrient concentration, supporting environmental determinism. All measured characters displayed variation along the gradient. Stomatal characters (size and density) had significantly less variation than morphometric characters (trunk diameter, stipe length and blade length), but stomatal density also shows interesting intraspecific patterns. In general, patterns within the fern community suggest a strong influence of species identity, especially of species inhabiting the lower edge of the cloud forest, which showed the clearest morphometric and stomatal patterns, associated to contrasting environments rather than to changes in elevation. The coincidence between morphometric and stomatal patterns in this area suggest hydraulic adjustments in response to contrasting environments. Our results provide evidence that tree ferns species respond to environmental changes through adjustments of morphometric plasticity and stomatal density, which is relevant to predict possible responses to variation in environmental conditions resulting from climate change.

Character state diversity of Litsea (Lauraceae) leaves in Cianjur Herbarium Hortus Botanicus Tjibodensis

Herbarium serves as a storage place for plants that have been preserved, both in the form of dry and wet preserves. The specimen material is useful in determining the taxonomic status or identity of a plant. Litsea is one of the genera of the Lauraceae tribe (kamper-kamperan) which has similar leaf morphological characters among the species in it or even with other genera that are still in one tribe. The study aims to explain the variation of leaf morphological characters of species of Litsea clan members derived from herbarium specimens of the Cianjur Herbarium Hortus Botanicus Tjibodensis (CHTJ) collection. The research method uses direct observation of specimens in a careful, detailed, high concentration, and still refer to the information data contained in the herbarium sheet. The results showed that the petiole length ranged from 0.7 cm to 3 cm, the petiole surface was hairy (glabrescent) and glabrous. Species of the genus Litsea have leaf shape (circumscriptio): oval (ovalis/ellipticus), elongated (oblongus), and lobed (lanceolatus); The leaf tip (apex folii) is pointed (acutus) in 5 species, and tapered (acuminatus) in 4 species, obtuse (obtusus) in 3 species; the leaf base (base folii) is rounded (rotundatus) in 4 species, obtuse (obtusus) in 5 species, and pointed (acutus) in 3 species; while the arrangement of leaf bones (nervatio or venation) is pinnate (penninervis). The species also have flat leaf margins (margo folii) (integer), with the leaf blade (intervenium) being paper-like and parchment-like, the leaf color is green, and the leaf surface has pilosus.

Character variation of root space microbial community composition in the response of drought-tolerant spring wheat to drought stress.

Drought is the most prevalent environmental stress in crop production, posing a significant danger to food security. Microorganisms in the crop root zone affect crop growth and development, enhance effective nutrient use, and resist adversity hazards. To analyze the changes and functional differences of root space microbial (endosphere-rhizosphere-bulk soil) communities in spring wheat under drought stress. In this study, the root, rhizosphere, and bulk soil of the drought-tolerant group (DTG, three varieties) and drought-sensitive group (DSG, three varieties) were collected. The control (CK, 25-28%), moderate drought (MD, 15-18%), and severe drought (SD, 9-12%) were analyzed by high-throughput sequencing and bioinformatics. The results showed significant differences in the diversity of Bacteria and Fungi in the root space of spring wheat under drought stress (P < 0.05), with the drought-tolerant group exhibiting higher microbial diversity. The microbial community change in spring wheat root space was mainly determined by the niche differentiation of endosphere, rhizosphere, and bulk soil and declined from endosphere to bulk soil due to drought. The antagonism between microbial and root-space species increased, and the community's complexity and stability deteriorated. Enriching drought-resistant preference groups like Actinobaciota, Variovorax, Streptomyces, and Conocybe altered the structure and function of the microbial community in the root space of spring wheat. Spring wheat's root space Bacteria and Fungi have different strategies to respond to drought.
