We present the nucleotide sequence of the gene encoding subunit 3 of cytochrome c oxidase in Chondrus crispus, the first report on a mitochondrial gene from a red alga. Amino acid alignment with homologous proteins shows that tryptophan is specified by UGA, as in the mitochondrial code of most organisms other than green plants. However, phylogenetic analyses of cox3 amino acid and nucleotide se...

The programs of managing waste materials in developing countries are often unsatisfactory and the unreasonable disposal of waste is a major issue in the worldwide. The main aim of the current study is to: Assess the applicability of Rumex crispus L. in removing heavy metals from the contaminated wastewater effluent form Pharmaceutical laboratories by bio-adsorption method. The dried R. crispus ...

Future climate change has been predicted to affect the potential distribution of plant species. However, only few studies have addressed how invasive species may respond to future climate change despite the known effects of plant species invasion on nutrient cycles, ecosystem functions, and agricultural yields. In this study, we predicted the potential distributions of two invasive species, Rum...

characteristics of diversity, abundance, distribution, and ecological status of aquatic macrophytes were observed in 2000 and 2007 on a circa 4.5 km long section of the turiec river using Kohler ́s method. In comparison to 2000, the total number of macrophytes in 2007 increased markedly (from 25 to 35), although only the numbers of amphiphytes and helophytes were changed substantially. the numbe...

Submerged aquatic macrophytes such as Potamogeton crispus can absorb large quantities of nutrients from sediment and water, and therefore mitigate pollution and improve water quality of polluted lakes. Turions are the main propagules of P. crispus; their formation is an important process in the life cycle of the plant and relates closely to the population dynamics of the species in lakes. The c...

The marine world is incredibly rich in brilliant and intense colours. Photonic structures are found in many different species and provide extremely complex optical responses that cannot be achieved solely by pigments. In this study we examine the cuticular structure of the red alga Chondrus crispus (Irish Moss) using anatomical and optical approaches. We experimentally measure the optical respo...
