Endomorphic Investigations on Foliar Epidermis of Some Acanthaceae | Chapter 9 | Contemporary Research and Perspectives in Biological Science Vol. 9

Of late, Indian research workers investigated the occurrence, structure, development and taxonomic significance of foliar epidermal features of the family. This contribution communicates observations on foliar epidermal characteristics of hitherto uninvestigated 22 species pertaining to 17 genera of the family Acanthaceae. Except for a few other types, the diacytic type of stomata is generally observed. The other types are rarely to occasionally noted on the same foliar surface. The other foliar features such as stomatal index and frequency, types of subsidiaries, stomatal abnormalities, cell inclusions, cell wall contours, etc. are presented in detail. Their systematic value is pertinently, earmarked especially at specific rank. The stomates although mostly diacytic type show the features e.g. distribution of stomata, types of subsidiaries, cell wall contours, presence/absence of cystoliths, their distribution and other characteristics that appear important in the identification of different taxa at specific ranks.

Significance of Petiolar Anatomy in Taxonomy of Acanthaceae | Chapter 6 | Advanced Research in Biological Science Vol. 7

 The paper reports observations on anatomy of petioles earlier uninvestigated 9 class belonging to 6 genera of the classification Acanthaceae. The species intentional are Pachystachys lutea Nees, Peristrophe montana Nees, Pseuderanthemum malabaricum (C. B. Clarke) Gamble, P.reticulatum Radlkf, Rungia parviflora  (Retz.) Nees, Staurogyne zeylanica (Nees) O.Ktze, Stenosiphonium cordifolium (Vahl ) Alston, S.parviflorum T. Anders and S.russellianum Nees. The petioles are usually circular or broadly circular in outline and adaxially channeled. The scope of development of endomorphic physiognomy and their distribution, inclusive of container inclusions, are described. The vasculature is mainly resolved into a main prominent arc in addition to few or none vascular bundles. The bodily patterns showed great alternative in the epidermis, extensions, pattern of vascular supply and sclerenchyma surrounding it, cell additions, etc., and should be considered orderly important individualities in the future. A key helping labeling of taxa investigated is determined based on these characters. Bodily characters are continual and conservative and thus have potential to be secondhand in plant taxonomy.

Influence of Climatic Changes on the Distribution of Geographical Spaces from the Floating Ivory Coast: Case of the Family of Acanthaceae | Chapter 7 | Recent Research Advances in Biology Vol. 5

 The aim of this research is to determine the diversity of Acanthaceae species in Ivory Coast, as well as the effect of climate change on their distribution. Variations in climatic variables including precipitation and temperature are likely to have an effect on biodiversity and the spatial distribution of species-friendly ecosystems. The habitats of Dicliptera alternans Lindau, Elytraria ivorensis Dokosi, and Whitfieldia lateritia Hook. were modelled using the concept of «Maximum Entropy» under current and future climatic conditions (horizon 2050/scénario A2). These species were chosen based on the number of occurrences on the one hand, and the endangered existence of the species on the other. The species' contact information was gathered and combined with bioclimatic data from the www.worldbioclim.org database. For each species, the surface of the theoretically desirable zones of distribution (or not) was determined. The record retrieval revealed a total of 106 species, classified into 39 groups, with 16 percent of them being endemic to the Ivory Coast. On the local list of endangered and rare species of the Ivory Coast of Aké-Assi L., 7 species are listed. The results show that the environmental variable «Seasonal variation of temperature (Bio 4) » is the environmental variable that contributed the most to the prediction of the model of the species Dicliptera alternans Lindau, Elytraria ivorensis Dokosi, and Whitfieldia lateritia by 2050. The A2 scenario predicts that by 2050, the surface area of the species' potentially favourable zones will be decreased by 67.66 percent, 3.35 percent, and 1.17 percent, respectively, for Dicliptera alternans Lindau, Elytraria ivorensis Dokosi, and Whitfieldia lateritia Hook. Despite these changes, the findings indicate that protected areas in Ivory Coast remain refuges for species of the Acanthaceae family under current and potential environmental conditions. This research backs up the effect of climate change on the spatiotemporal distribution of organisms. This study would assist in better directing conservation and management decisions for protected areas as biodiversity refuges.
