This review discusses phytoextraction and phytostabilisation of acid mine drainage (AMD) alongside with their benefits and limitations with case studies. Furthermore, plants associated with these two approaches of phytoremediation and impact of AMD on aquatic macrophytes used for phytoremediation were also reviewed. Both phytoextraction and phytostabilisation approaches are promising technologies in remediating AMD. However, their limitation of low metal removal and the lack of knowledge of minimum amendments required for their effective remediation call for the proposal, herein made, to combine aquatic macrophytes, as well as include plants from a wide range of families capable of phytoextraction and phytostabilisation in the remediation of AMD. Keywords: aquatic macrophytes, conventional treatment, hyperaccumulators, phytoremediation Introduction The activities of the mine cause the production of acidic water that flows down to nearby water bodies causing long term impairment to biodiversity and waterways. The acidic water produced by the mines is termed acid mine drainage (AMD). Acid mine drainage also known as acid rock drainage is a process that occurs as a result of the contact between oxygenated water and mineral pyrite which leads to the oxidation of the pyrite and the production of acids (Evangelou, 1995; Blowes et al., 2003).

Anil Loveson, Rajathy Sivalingam and Syamkumar R. School of Environmental Studies, Cochin University Of Science and Technology Abstract: This study involved a laboratory experiment on the efficiency of the plant duckweed Spirodela polyrrhiza in improving the quality of two polluted wetlands of Eloor industrial area, Ernakulam, Kerala. The efficiency was tested by measuring some of physicochemical characteristics of the control and plant treatments after each eight days. All the parameters show considerable rate of reduction. In wetland I, The highest rates of reduction after 8 days of treatment were for heavy metals, accounting 95%, 79%, and 66% for Lead, Copper and Zinc, respectively, followed by 53% for Chromium, 45% for Mercury, 26% for Cobalt, 20% for manganese and 7% for Nickel. Other factors like pH, BOD, COD, Nitrate, Phosphate , sulphate, TDS, TSS and Turbidity reduced by 12%, 37%, 49%, 100%, 36%, 16%, 53%,85% and 52% respectively. In wetland II also heavy metals were removed with Cd(100%), Fe(98%), Pb(91%), Cu(74%) Zn(62%) and Hg(53%) removed more efficiently. The results showed that this aquatic plant can be successfully used for wastewater pollutants removal. Other physiochemical parameters like pH, BOD, COD, Nitrate, Phosphate , sulphate, TDS, TSS and Turbidity reduced by 14%, 40%, 60%, 100%, 38%, 65%, 73%, 85%, and 51% after 8 days of treatment.

We suggest a method of constructing red numbers for plant species, in order to set priorities in con- servation policy. The red number is an additive index, summarising values of four parameters: 1. Rarity – The number of sites (1 km2) where the species is present. A rare species is defined when present in 0.5% of the area or less. 2. Declining rate and habitat vulnerability – Evaluate the decreasing rate in the number of sites and/or the destruction probability of the habitat. 3. Attractivity – the flower size and the probability of cutting or exploitation of the plant. 4. Distribution type – scoring endemic species and peripheral populations. The plant species of Israel were scored for the parameters of the red number. Three hundred and seventy (370) species, 16.15% of the Israeli flora entered into the “Red List” received red numbers above 6. “Post Mortem” analysis for the 34 extinct species of Israel revealed an average red number of 8.7, significantly higher than the average of the current red list.

A. 3 Author for correspondence ( [email protected] ) Communicating Editor: Javier Francisco-Ortega Abstract— Previous attempts to resolve relationships among the primary lineages of Campanulidae (e.g. Apiales, Asterales, Dipsacales) have mostly been unconvincing, and the placement of a number of smaller groups (e.g. Bruniaceae, Columelliaceae, Escalloniaceae) remains uncertain. Here we build on a recent analysis of an incomplete data set that was assembled from the literature for a set of 50 campanulid taxa. To this data set we first added newly generated DNA sequence data for the same set of genes and taxa. Second, we sequenced three additional cpDNA coding regions (ca. 8,000 bp) for the same set of 50 campanulid taxa. Finally, we assembled the most comprehensive sample of cam- panulid diversity to date, including ca. 17,000 bp of cpDNA for 122 campanulid taxa and five outgroups. Simply filling in missing data in the 50-taxon data set (rendering it 94% complete) resulted in a topology that was similar to earlier studies, but with little additional resolution or confidence.

Everyone was determined to make the most of sunshine on the first day of what for many, was their first real trip out in almost 18 months. We headed straight out on the Lizard peninsula past Culdrose Naval station and through the pretty village of Gunwalloe, down to Church Cove. Every hedge was hazed navy blue with Bluebells and clouds of Cow Parsley brushed the van on the narrow lanes. In glorious late afternoon sunshine, we wandered out of the car park towards the cove. The Cornish hedges were covered in the glossy green leaves of Sea Beet (Beta maritima) interspersed with Danish Scurvygrass (Cochlearia danica) that was coming to the end of its flowering season. As we got nearer to the beach, one wall was covered from top to bottom with a blanket of Sea Sandwort (Honckenya peploides) in full flower. The cliffs were dotted with Common Scurvygrass (Cochlearia officinalis) and huge mounds of Thrift (Armeria maritima). Up on top of the cliffs we came across our first blue Spring Squills (Scilla verna).

(2012): Red List of vascular plants of the Czech Republic: 3rd edition. – Preslia 84: 631–645. The knowledge of the flora of the Czech Republic has substantially improved since the second ver- sion of the national Red List was published, mainly due to large-scale field recording during the last decade and the resulting large national databases. In this paper, an updated Red List is presented and compared with the previous editions of 1979 and 2000. The complete updated Red List consists of 1720 taxa (listed in Electronic Appendix 1), accounting for more then a half (59.2%) of the native flora of the Czech Republic. Of the Red-Listed taxa, 156 (9.1% of the total number on the list) are in the A categories, which include taxa that have vanished from the flora or are not known to occur at present, 471 (27.4%) are classified as critically threatened, 357 (20.8%) as threatened and 356 (20.7%) as endangered. From 1979 to 2000 to 2012, there has been an increase in the total number of taxa included in the Red List (from 1190 to 1627 to 1720) and in most categories, mainly for the following reasons: (i) The continuing human pressure on many natural and semi-natural habitats is reflected in the increased vulnerability or level of threat to many vascular plants; some vulnerable species therefore became endangered, those endangered critically threatened, while species until recently not classified may be included in the Red List as vulnerable or even endangered.

Received 17 October, 2014; Accepted 3 December, 2014 Heavy metals such as arsenic (As), copper (Cu), chromium (Cr), Hg, lead (Pb) and cobalt (Co) cause adverse effects on living organisms by their toxic nature. To remove heavy metals, a variety of conventional treatment technologies have been tested which are not economical and user friendly. So, natural remediation method such as phytoremediation is becoming more popular where plants are used. Phytoremediation is a cost effective and eco-friendly method. This paper accounts the study to exercise the phytoremediation potential of the aquatic plant Spirodela polyrhiza for arsenic and copper removal from water. To carry out the study, six plastic bowls each carrying 1 L distilled water were taken where arsenic and copper of known concentration was added for preparing a solution, which contained 1.0, 0.9, 0.7, 0.6, 0.5, and 0.3 mg/L of arsenic and 5.0, 4.6, 4.2, 3.8, 3.4 and 3.0 mg/L of copper.
