Studies on the ecology of Chrozophora tinctoria L. and Rubia tinctorum L. in Western Anatolia

This study was carried out to determine the autecological and economic importance of Chrozophora tinctoria L. (Euphorbiaceae) and Rubia tinctorum L. (Rubiaceae) distributed in western Anatolia. A Physical and chemical analysis was performed on the soils where these plants grow and a chemical analysis of the plants was also carried out. The results obtained were assessed using regression analysis. It was found that both of the plants generally grow on loam and clayey-loam; neutral to slightly alkaline soils which are both poor and rich in calcium carbonate; slightly saline; moderately rich, rich and very rich in organic matter; rich and moderately rich in phosphorus; and high and very high in potassium content

Trace element pollution biomonitoring using the bark of Pinus brutia Turkish red pine in the Western Anatolian part of Turkey

Back ground: Pinus brutia Ten (Turk ish red pine) is a widespread ev ergreen tree in the Med i ter ra nean and Aegean re gions of Tur key. Meth ods: The barks of red pine were tested as a pos si ble biomonitor of trace el e ment pol lu tion stud ied in the West ern Ana - to lian part of Tur key. Samples col lected from con trol, in dus try, road side, sub ur ban and ru ral ar eas from 30 lo ca tions in the study area were in ves ti gated. The con cen tra tion of cad mium, lead, chro mium, iron, nickel and cop per were de termined in the bark of the red pine by atomic ab sorp tion spec trom e try. Re sults: As re sults of this study, the fol low ing con cen trations were de termined: Cd: 0.60 – 0.71 µg g–1, Pb: 4.59 – 20.03 µg g–1, Cr: 0.44 – 3.17 µg g–1, Fe: 486.35 – 1274.04 µg g–1, Ni: 3.56 – 18.87 µg g–1 and Cu: 3.52 – 15.30 µg g–1. Con clu - sion: The results of this study imply that barks of P. brutia can be a use ful biomonitor for the de termin ing heavy metal pollu tion in an area

A study on the soil-plant interactions of some Cistus L. species distributed in West Anatolia Batι Anadolu'da Yayιlιş Gösteren Bazι Cistus L. türlerinin toprak-bitki i̇lişkileri Üzerine bir Çalιşma

This study was undertaken with the aim of examining the soil-plant interactions of Cistus creticus L. and Cistus salviifolius L. in West Anatolia. The soil analysis data showed that these plants grow in different kinds of soils with sandy-clayey-loam, clayey-loam and loamy texture. The soils in general are not saline but are moderately and slightly alkaline, being rich in nitrogen and having a low level of phosphorus and potassium. They are unaffected by the calcium carbonate content in soils. A negative relation was observed in C. creticus after regression analysis between plant calcium and soil phosphorus, plant calcium and soil salts, but a positive relation between plant calcium and soil calcium carbonate. In C. salviifolius, there was a positive relation between plant calcium and soil pH

Biomonitoring of zinc and manganese in bark of Turkish red pine of western Anatolia

Turkish red pine (Pinus brutia) is a widespread evergreen tree in Mediterranean and Aegean regions of Turkey. The barks of Pinus brutia were tested as a possible biomonitor of Zn and Mn accumulation studied in Western Anatolia, Turkey. Samples collected from industry, roadside, suburban and rural areas from thirty locations in the study area were investigated. The concentration of zinc and manganese were determined in the bark of the red pine by atomic absorption spectrometry. As a result of this study, the following mean concentrations were determined: for Zn between min 8.4 and max 14.1 µg g-1, and for Mn between min 19.1 and max 24.0 µg g-1. It was found that there is no affect of location on the element concentration of both Mn and Zn

Role of national parks in Turkey - A case study from Dilek peninsula-great Menderes Delta National Park

A survey was conducted in Dilek peninsula-Great Menderes Delta national park, with an area of 10.985 ha. Studies were undertaken during 1998-2001. Vegetation types including 3 new associations namely Urgino-Quercetum cocciferae, Querco-Oleatum europaea and Pistacio-Ceratonietum siliquae are reported for the first time from the area together with a list of over 50 endemics and endangered taxa like Campanula tomentosa. Land degradation practices due to demographic pressures, land clearence, fires and tourism are discussed
