The effect of concentrations 0(control), 250, 500, 1000, 2000 and 4000 µM of aluminum on the growth rate and content total chlorophyll of Dunaliella salina strain UTEX-200 has been studied for duration of 27 days. The results indicated that an increase in aluminum concentration resulted in a decrease in the growth rate and chlorophyll content. It seems that these effects are probably due to des...
Although planktonic algae are a basic component of freshwater ecosystems, studies on their diversity and species distribution still not in satisfactory numbers. This study aims to contribute Turkish algal flora particularly with the new records reported. A total 158 Charophyta taxa were determined conducted from 2017 2019 25 river basins Turkey. In this study, while highest taxon was found Saka...
Macaronesia, which includes five mid-Atlantic archipelagos (Azores, Madeira, Selvagems, Canaries, and Cape Verdes), has been traditionally recognized as a distinct biogeographic unit whose circumscription has been intimately associated with the hypothesis that the flora is a relict of a formerly broadly distributed subtropical Tertiary flora. The concept of Macaronesia is revisited here using p...
ABSTRACT The present work aims to describe the sampling design and methods used in series “Periphytic algal flora of Lower Doce River basin (Espírito Santo State, Brazil) after ore tailings flow”. This will biodiversity periphytic algae registered during Aquatic Biodiversity Monitoring Program, Environmental Area I, carried out three years passage from Fundão dam (Mariana, Minas Gerais).

nvestigations on indigenous and non-indigenous invasive flora fauna of a certain geographical area are always important to assess their impact native biodiversity control spread by making conservation strategies protect biodiversity. In this study, we have encountered overwhelming growth six seaweed species, Caulerpa racemosa, C. serrulata, sertularioides, taxifolia, peltata, Halimeda opuntia t...
The aim of this study is to determine the effect of environmental conditions with emphasis on the main meteorological factors (air temperature variables, sunshine hour, and humidity), on phytoplankton communities. As important primary producers in aquatic ecosystems, phytoplankton communities could be affected by several factors. Environmental factors play the major role in occurrence and diver...
