Air pollution index of different sites and soil pollution indices were<br />calculated. The metal contamination in the soils was evaluated by calculating<br />enrichment factor (EF), contamination factor (CF), geo-accumulation index (Igeo) and<br />pollution load index (PLI). Soil quality for total heavy metals in the study area was<br />evaluated. The factory was found to change the reaction of the soil to become acidic<br />and all heavy metals were shown to be high at the factory site and decreased with<br />increasing the distance from the factory. This pollution of the environment caused<br />changes in the vegetation of the study area.https://taec.journals.ekb.eg/article_11938_06787f1ecc7918b745b86fa595493d83.pdfCairo University Herbarium (CAI)Taeckholmia1110-741336120161231Late Carboniferous Macroflora from Rod El-Hamal Formation Wadi Araba, North Eastern Desert, Egypt45571193910.21608/taec.2016.11939ENMonaDarwishDepartment of Botany, College of Women for Science, Arts and Education, University of Ain Shams,

Field data were collected from three major crops: wheat as a winter crop, millet as summer crop and alfa-alfa as a perennial crop. 146 stands (fields) from 8 sites in Qena Governorate were permanently visited during 2013 and 2014. A total of 169 species (105 annuals, 64 perennials) of the vascular plants belonged to 121 genera in 39 families constituted the flora of the study area. The most species-rich families were Poaceae, Asteraceae, Fabaceae, Brassicaceae, Chenopodiaceae, and Euphorbiaceae. Annual herbs were the best represented life form, followed by annual grasses, trees and perennial shrubs. Ballochore and pogonochore were the most represented dispersal types of seeds, while cyclochore and auxochore were the least represented. 26 species were categorized as dominants (highest Q-values), where they have a wide ecological range of distribution. Classification of the associated vegetation in 146 stands by cluster analysis yielded 5 vegetation groups (A-E); the vegetation groups A and E were mainly represented by weeds in wheat and alfa-alfa (winter season), while most the stands of groups B, C and D were represented by species in millet and alfa-alfa (summer season). These groups were separated along the first two axes of Bray-Curtis ordination.https://taec.journals.ekb.eg/article_11940_16b37173b49fda2ab1cd9d7bd1a4d113.pdfCairo University Herbarium (CAI)Taeckholmia1110-741336120161201Leaf Anatomy, Chemical Composition as Well as Essential Oils and their Antibacterial Activity of Some Lauraceous Taxa771011194310.21608/taec.2016.11943ENAl-SafaMohamedBotany Department, Faculty of Science, Ain Shams University, EgyptWafaaAhmedBiology Department, Faculty of Science, Ban ghazi University, Libya Government.EinasElshatouryMicrobiology Department, Faculty of Science, Ain Shams University, Egypt.MagdyMouradBotany Department, Faculty of Science, Ain Shams University, Egypt.Journal Article20160710Eight taxa of Lauraceae representing four genera were subjected to the present study. The<br />micro-morphological and chemical investigation were carried out according to traditional<br />methods. The objective of the present study is to find criteria to facilitate the delimitation and<br />identification of the taxa under investigation. The obtained leaf micro-characters were<br />considered diagnostic at the generic and specific level. The extracted chemical compounds<br />from the taxa under investigation ranged from 41-61. Most of tested oils showed antibacterial<br />activity toward six bacteria strains. The most potent antibacterial oils were from<br />Cinnamomum glanduliferum and C. verum. The antibacterial activity was due to oxygenated<br />and non-oxygenated monoterpenes (α-pinene, β-pineneandcineole). The antibacterial activity<br />of Apollonias barbujana is due to (α-phellandrene rather than cineole). The obtained data<br />from an anatomical and chemical point of view can be considered diagnostic at the<br />infraspecific level, but only to a certain extent.https://taec.journals.ekb.eg/article_11943_0a66518d3d4345144a99befd2554c6a5.pdfCairo University Herbarium (CAI)Taeckholmia1110-741336120161231Chromosome count and karyotype study on endemic species Silene schimperiana Boiss.

Four main clusters are recognized viz. Sterculiaceae s.s. cluster, Tiliaceae- Exemplars of Strerculiaceae cluster, Malvaceae s.s. cluster and Bombacaceae s.s. – Exemplars of Sterculiaceae and Malvaceae cluster. The results delimited Sterculiaceae s.s. and Tiliaceae s.s. to containing the genera previously included in tribes Sterculieae and Tilieae respectively; also confirmed and verified the segregation of Byttnerioideae of Sterculiaceae s.l. and Grewioideae of Tiliaceae s.l. to be treated as distinct families Byttneriaceae and Spermanniaceae respectively. Our analysis recommended the treatment of subfamilies Dombeyoideae, Bombacoideae and Malvoideae of Malvaceae s.l. as distinct families: Dombeyaceae, Bombacaceae s.s. and Malvaceae s.s. and the final placement of Gossypium and Hibiscus in either Malvaceae or Bombacaceae is uncertain, as well as the circumscription of Pterospermum is obscure thus further study is necessary for these genera.https://taec.journals.ekb.eg/article_11956_9501c70e3270bf6ba9a09abb16349c89.pdfCairo University Herbarium (CAI)Taeckholmia1110-741336120161231Variations in floristic composition of wild and cultivated species associated with Moringa oleifera Lam. in Egypt1361571195710.21608/taec.2016.11957ENAhmedMobarakBotany Department, Faculty of Science, Benha University, EgyptKamalShaltoutBotany Department, Faculty of Science, Tanta UniversityHusseinAliForestry and Wood Technology Department, Faculty of Agriculture, Alexandria University, EgyptDinaBarakaBotany Department, Faculty of Science, Benha University, EgyptSaadiaAlyBotany Department, Faculty of Science, Benha University, EgyptJournal Article20161120The aim of this work is to study the cultivated and wild species associated with Moringa oleifera in different sites in Egypt. The cultivated species were 174 related to 145 genera and 67 families, while the wild species were 45 related to 39 genera and 21 families. Fabaceae was the most represented cultivated family (15 species), while Poaceae was the most represented wild family (8 species). Phoenix dactylifera and Portulaca oleracea were the most common cultivated and wild species, respectively. Phanerophytes were the most represented life form, regarding the cultivated species (79.5%), whereas therophytes were the most represented life form (62.2%). The application of Two Way Indicator Species Analysis (TWINSPAN) on the floristic composition of the sampled stands led to classify them into 7 vegetation groups at level 5 for the cultivated species, and 5 groups at level 3 for the wild species. The cultivated groups were named according to their dominant species as follows: Ficus elastica, Abutilon hirtum, Cordia myxa, Carya illinoensis, Azadirachta indica, Ficus benjamina and Ceiba speciosa. In addition, the wild groups were: Pancratium maritimum, Digitaria ciliaris, Cyperus rotundus, Lantana camara and Bidens pilosa.https://taec.journals.ekb.eg/article_11957_87d170967f21ebdad8ba3b91c864e5a2.pdf
