    Environmental relationships of the vascular flora alongside the railway tracks between Haydarpa a and Gebze (Istanbul-kocaeli/Turkey)
    (Triveni Enterprises, 2015) Altay, Volkan; Ozyigit, I. I.; Osma, E.; Bakir, Y.; Demir, G.; Severoglu, Z.; Yarci, C.
    The vascular flora alongside the railway track between Haydarpasa and Gebze in Turkey was investigated and the floristic features of the study area are presented here. The investigation was undertaken during 2003-2009. In total 194 plant taxa were determined. Out of these 174 were naturally growing and 20 were exotics and cultivated. Native taxa within the flora belonged to 135 genera and 50 families, exotic and. cultivated taxa belonged to 20 genera and 15 families. The members of Dicotyledonae constituted of 82.76% and Monocotyledonae 16.09% of the native taxa. The highest number of these taxa belonged to Asteraceae family (25 species), while the exotics were from Rosaceae (5 species). The plant distributional features, phytogeographical elements, life forms, archaeophytes and neophytes and status of invasive plants have also been included.

    Preservation and ecology of a living relict shrub in South Caucasus as a eco-genetic heritage from Tertiary: Epigaea gaultherioides (Boiss. & Bal.) Takht
    (Triveni Enterprises, 2020) Ozturk, M.; Altay, V; Kucuk, M.; Altundag, E.; Severoglu, Z.; Yalcin, I. E.
    Aim: Epigaea gaultherioides is an euxine element with a tertiary origin as a relict species facing threat of extinction. In this study, an attempt was made to explore the ecological characteristics by taking into consideration the soil-plant interactions of this taxon. Methodology : Soil and plant samples were collected and analysed using Kjeldahl, Spectrophotometer, Flame photometer and ICP-OES. Results : The findings showed that generally grows on sandy and/or clayey soils, of strong acidic nature, non-calcified, non-saline and high in organic matter. The plant samples collected from the study area were thin iron, aluminium, zinc and nickel; but their percentage in the soils was low. Interpretation : The findings of this study will assist to better understand the ecological requirements of this relict taxon for its possible future successful conservation programs.
