The fern is one of the highly diverse vascular plant species, which has a unique characteristic. The closely related at the family level because the genera within each family have some uniformity so that the relationship and groupings cannot be distinguished. One example of a diverse fern family is Polypodiaceae. Consequently, it is necessary to simplify the classification; one of them is through phenetic relationship analysis. This study aimed to analyze the phenetic relationship of the Polypodiaceae ferns in Climbing Cemoro, Mouth Lawu enclosure, Karangayar Regency, based on the similarity index on the dendogram. The data were collected using the exploration method and the sporophyte morphological characters were observed. The observations obtained 13 variations of characters. The relationship analysis was carried out with the hierarchical cluster program using SPSS 23. There were six species found from the Polypodiaceae family, there were including Belvisia mucronata, Goniophlebium sp, Lepisorus sp, Pyrrosia piloselloides, Crypsinus taeniatus and Drynaria sparsisora. The finding suggests that six species are divided into two clusters, the Group I consisting of Goniophlebium sp, Lepisorus sp, Lepisorus sp, and Pyrrosia pilloselloides with a similarity coefficient index of 53% and Group II consisting of Drynaria sparsisora, Goniophlebium sp, and Pyrrosia piloselloides with a similarity index of 46%.

Abstract. Rindyaastuti R, Hapsati L, Wibowo AT. 2021. Analysis of morphological characteristics and phenetic relationship of ebony (Diospyros spp.) in Indonesia. Biodiversitas 22: 2738-2753. Diospyros L. (Ebenaceae) is an economically important genus that covers over 500 plant species. Members of this group are known to produce hard, dark, high-quality timbers known as ebony trees, while other members are known as persimmon trees. There is limited information on the morphological characters and phenetic relationship of this genus from Indonesian archipelago. In this work, we reported the phenetic clustering of 14 species of Indonesian Diospyros, based on plant habit, stem, leaves, and fruit characters, which was analysed using UPGMA and Jaccard similarity index. The phenetic dendrogram divided the 14 species of Diospyros into two main clusters which separating Subgen. Maba and Eudiospyros. Further, subgen. Maba was clustered into a single cluster while subgen. Eudiospyros was divided into 3 sub-clusters as sister groups. The clustering in Eudiospyros was supported by low SI and bootstrap value, demonstrating the high morphological variation of the subgenus. The sectional separation of Diospyros spp. was considered as paraphyletic. In general, our phenetic clustering exhibited suitability and relevancy with previous classification. Fruit size and trichomes are very important in this phenetic clustering, especially to form Eudiospyros subgenus. Fruit trichomes were also special characters related to biogeographical distribution following the Wallace line theory.

В статье представлены материалы о взаимосвязи продолжительности продуктивного использования коров с характеристикой устойчивости к деградации, с возрастом отела и удоем. В исследованной, разнородной по происхождению, группе животных для прогноза продуктивного периода коров, обусловленного устойчивостью к деградации и возрастом первого отела, пригодно уравнение регрессии, аргументами в котором являются индекс устойчивости, возраст первого отела в первой и второй степенях. Коэффициент корреляции межу предсказанными значениями продуктивного периода и его фактическими величинами в I группе составляет 0,502, во II - 0,604. При этом крайние варианты прогнозируются со статистическими ошибками 5 мес при оценке индекса устойчивости по 2 лактациям и 4,1 мес по 3, а средние варианты, соответственно, 1,6 и 1,51 мес. Индекс устойчивости к процессу старения является важной характеристикой биологических особенностей коров, определяющий их продуктивное долголетие. Его оценка по первым 2 и 3 лактациям имеет прямолинейную связь с продуктивным периодом (r=0,4109 и r=0,5270), соответственно. Зависимость продуктивного периода от возраста первого отела криволинейная — с увеличением возраста первого отела сокращается срок продуктивного использования, при возрасте первого отела более 1400 дней срок продуктивного использования колеблется от 1,33 до 1,41 лактации. Коэффициент корреляции между этими характеристиками коров составляет - 0,2164 в I и - 0,2620 во II группах. The article presents materials about the relationship of the duration of productive use of cows with the characteristic of resistance to degradation, with the age of calving and milk yield. In the studied group of animals, which is heterogeneous in origin, the regression equation is suitable for predicting the productive period of cows due to resistance to degradation and the age of the first calving, the arguments of which are the stability index, the age of the first calving in the first and second degrees. The correlation coefficient between the predicted values of the productive period and its actual values in group I is 0.502, in group II - 0.604. At the same time, the extreme variants are predicted with statistical errors of 5 months when evaluating the stability index for 2 lactations and 4.1 months for 3, and the average variants, respectively, are 1.6 and 1.51 months. The index of resistance to the aging process is an important characteristic of the biological characteristics of cows, which determines their productive longevity. Its estimate for the first 2 and 3 lactations has a direct relationship with the productive period (r=0.4109 and r=0.5270), respectively. The dependence of the productive period age at first calving curvilinear with increasing age at first calving reduces the time to productive use, while age at first calving of more than 1400 days, the period of productive use ranges from 1.33 to 1.41 lactation. The correlation coefficient between these characteristics of cows is-0.2164 in I and-0.2620 in II groups.

The article presents the results of a long-term study of the features of the phytocenology of agrophytocenoses of oil radish using different methods for assessing their condition and studying the tactics of the plant vitality strategy. A comprehensive assessment was made of the effect of changes in row spacing, seeding rates and fertilizer rates on the formation of various plant morphotypes, the variability of morphological characters and the general characteristics of plant viability. Three idiotypes of the plant oil radish were identified in a vertical study of agrophytocenosis, on the basis of which a detailed analysis of the variability of each group and a statistical assessment of the reliability of its existence were carried out. The features of the morphological integration of each tier are analyzed and its impact on the formation of the overall field productivity is evaluated. Based on the modular and vitality grouping, the effectiveness and feasibility of combining various options for plant density and fertilizer in the range of 30-90 kg of active substance per 1 ha were evaluated. Conclusions are drawn about the desired model of agrophytocenosis of oil radish based on the characteristics of its vital tactics and the goals of its growing. Grouping was carried out according to a variety of morphological traits of plants in the population and the possibilities of applying the basic patterns of phytocenology in their application to radish oilseed plants were evaluated. Through the use of regression analysis, the influence of climatic conditions on the formation of various morphological types of plants and the nature of the relationship of plants of oil radish in cenoses of various densities against the background of various fertilizer options has been evaluated. The main promising areas for further research on the peculiarities of creating highly productive and highly adaptable agrophytocenoses of oil radish have been outlined.

Abstract Deuber (2006) investigated variation in spoken Nigerian Pidgin data by educated speakers and found no evidence for a continuum of lects between Nigerian Pidgin and English. Many speakers, however, speak both languages, and both are in close contact with each other, which keeps the question of the nature of their relationship on the agenda. This paper investigates 67 conversations in Nigerian English by educated speakers as they occur in the International Corpus of English, Nigeria (ice-Nigeria, Wunder et al., 2010), using the variability in copula usage as a test bed. Implicational scaling, network analysis and hierarchical cluster analysis reveal that the use of variants is not randomly distributed over speakers. Particular clusters of speakers use particular constellations of variants. A qualitative investigation reveals this complex situation as a continuum of style, with code-switching as one of the stylistic devices, motivated by such social factors as formality, setting, participants and interpersonal relationships.

The specific objectives of this BARD proposal were: Use a comparative genomics approach to identify T3Es in group I, II and III strains of A. citrulli. Determine the bacterial genes contributing to host preference. Develop mutant strains that can be used for biological control of BFB. Background to the topic: Bacterial fruit blotch (BFB) of cucurbits, caused by Acidovoraxcitrulli, is a devastating disease that affects watermelon (Citrulluslanatus) and melon (Cucumismelo) production worldwide, including both Israel and USA. Three major groups of A. citrullistrains have been classified based on their virulence on host plants, genetics and biochemical properties. The host selection could be one of the major factors that shape A. citrullivirulence. The differences in the repertoire of type III‐ secreted effectors (T3Es) among the three A. citrulligroups could play a major role in determining host preferential association. Currently, there are only 11 A. citrulliT3Es predicted by the annotation of the genome of the group II strain, AAC00‐1. We expect that new A. citrulliT3Es can be identified by a combination of bioinformatics and experimental approaches, which may help us to further define the relationship of T3Es and host preference of A. citrulli.   Implications, both scientific and agricultural: Enriching the information on virulence and avirulence functions of T3Es will contribute to the understanding of basic aspects of A. citrulli‐cucurbit interactions. In the long term, it will contribute to the development of durable BFB resistance in commercial varieties. In the short term, identifying bacterial genes that contribute to virulence and host preference will allow the engineering of A. citrullimutants that can trigger SAR in a given host. If applied as seed treatments, these should significantly improve the effectiveness and efficacy of BFB management in melon and atermelon production.

AbstractIn the phylogenetic classification of the Lepidoptera, the position of the genital opening and its modifications help to clarify the relationship of the Zeugloptera to the lepidopterous suborders. Three different systems of the suborder classification of the Lepidoptera, into Homoneura and Heteroneura (Tillyard, Imms, etc.), Monotrysia and Ditrysia (Borner), and Dacnonypha, Monotrysia, and Ditrysia (Hinton), are not supported by evidence obtained in the study of the female genitalia.The development of the female terminalia is closely associated with the mode of oviposition. Several types of female terminalia are found in the primitive Lepidoptera (Hepialidae, Neopseustidae, Tischeriidae, Lyonetiidae, Agathiphagidae, Tineidae, Nepticulidae, and Eriocraniidae). They are divided into four categories: hepialid type — the eggs are dropped randomly; typical lepidopterous type — the eggs are laid on the surface of food plants; eriocraniid type — the eggs are laid inside the food plants; tineid type — the eggs are laid in crevices of food. Each of the types is derivable from the types occurring in Neopseustidae, Tischeriidae, Agathiphagidae, and Eriocraniidae, respectively. These types are still far removed from the type of female terminalia in Micropterygidae of the Zeugloptera.The modes of egg-laying as well as the morphological characters of the female genitalia must be taken into consideration in suborder classification of the Lepidoptera.A genealogical tree based on the female terminalia suggests four main branches: hepialid branch — includes Neopseustidae and Prototheoridae; typical lepidopterous branch — includes all Ditrysia and Nepticulidae; tineid branch — includes only Tineidae; eriocraniid branch — includes Incurvariidae, Prodoxidae, Adelidae, and Heliozelidae.

SummaryField and laboratory studies were carried out in 1981 and 1982 to investigate the relationship of stalk morphology and chemical composition to lodging resistance in maize in the rainforest zone of Nigeria.Morphological characters correlated with lodging were plant height, diameter and length of basal internode, thickness of rind and weight of 5 cm basal section. Lodging was negatively correlated with grain yield, and with the percentages of total nonstructural carbohydrate, protein and potassium in the stalks. Premature stalk senescence and rot were common in varieties susceptible to lodging. Lodging had no relationship with leaf area and number of days from sowing to flowering.

AbstractThe phylogeny of the Hydroporinae is investigated in a cladistic analysis emphasizing placement of the genus Peschetius Guignot, historically placed in the tribe Hydroporini. Sixty-nine adult and larval morphological characters were coded for 61 species of Hydroporinae representing eight of the nine tribes. Cladistic analysis of the data resulted in 396 most parsimonious cladograms (length = 176, CI = 46, RI = 80). The results indicate that the genus Peschetius is the sister group to the tribe Bidessini based mainly on an unambiguous character, the presence of a prominent internal spermathecal spine, and several other more ambiguous or homoplasious characters. The tribe Bidessini is expanded to include the genus Peschetius, and it is formally transferred from the tribe Hydroporini. Other results indicating interesting relationships of tribes and genera within Hydroporinae are also discussed. Results include; 1) a dramatically paraphyletic Hydroporini with Laccornellus Roughley and Wolfe, Canthyporus Zimmermann and Hydrocolus Roughley and Larson in basal positions within the phylogeny, 2) Hydrovatus Motschulsky and Queda Sharp resolved as sister groups and not closely related to Methlini van den Branden, 3) support for close relationship of Pachydrus Sharp (Pachydrini Biström, Nilsson and Wewalka) with Hyphydrini Sharp, 4) paraphyly of Hygrotus Stephens sensu lato with the relationship H. (Coelambus) Thomson + (Hygrotus sensus stricto + Hydrovatini)) suggesting recognition of Coelambus and Hygrotus as separate genera, 5) close relationship between the Australian genera of Hydroporini and Hyphydrini and 6) the nesting of Vatellini within a group of Hydroporini.
