The environmental state of important aquatic habitats in Albania based on algal assesment, a review

Lirika Kupe Aleko Miho

En Albania is rich in aquatic resources with high natural and biological values.Nevertheless,the waters still continue to be endangered,especially in western Adriatic Lowland areas.The structure of microscopic algae may give a better idea of water quality than traditional indicators.Systematic control of water quality will help to develop new strategies of wastewater management.It will allow Albania to reach international standards in environmental protection.

Littoral eutrophication indicators are more closely related to nearshore land use than to water nutrient concentrations: A critical evaluation of stressor-response relationships

The Science of The Total Environment (2020)

Susanne C. Schneider Vera Biberdžić Vjola Braho Biljana Budzakoska Gjoreska Magdalena Cara

Biological assessment metrics and water chemistry measurements are used to quantify the link between stressors and their effects on lake ecosystems, for the Water Framework Directive. However, correlations between metrics and water chemistry are often poor. This is seen as major weaknesses of Water Framework Directive-related monitoring and assessment. We analyzed macrophytes, benthic algae, benthic macroinvertebrates, water chemistry and sediment total phosphorus content in the littoral of six lakes in the Western Balkans and used CORINE land use data to estimate nutrient enrichment via runoff from the adjacent land. Lakes with a higher estimated phosphorus runoff from the adjacent land did not have higher littoral water nutrient concentrations, but littoral diatom assemblages indicated more eutrophic conditions. These lakes also had higher abundances of littoral benthic primary producers, which in turn were associated with low concentrations of dissolved nutrients, but only in autumn, not in spring. This is consistent with primary producers taking up nutrients during the summer growth season. In lakes with high abundances of benthic primary producers, it is likely that the littoral vegetation plays a large role in the transfer of nutrients from the water to the benthos. This process impairs correlations between biological metrics and water nutrient concentrations. Our results suggest that CORINE land cover may be more useful to characterize littoral nutrient enrichment than lake water chemistry. Increased benthic primary producer biomasses and "eutrophic" diatom indices may indicate littoral nutrient enrichment even if water nutrient concentrations are low.

Essential oil composition in three cultivars of Ocimum L. in Albania

Archives of Biological Sciences (2014)

Alma Imeri Lirika Kupe Julian Shehu Erta Dodona Nikoll Bardhi

Basil is an important medicinal and aromatic plant. This paper presents quantitative and qualitative analyses of the essential oils obtained from an autochthon cultivar of Ocimum basilicum L. and two other Italian cultivars, O. basilicum L. cv. purple and O. basilicum L green basil with wide leaves .In the volatile oil of O. basilicum L. cv. with green wide leaves, twelve components were characterized, representing 90% of the total oil, of which linalool (45.3 %) and eugenol (42.06 %) were the major components. In the volatile oil of O. basilicum L. cv. purple, nine components were characterized representing 90% of the total oil, of which farnesene (14.94%), elemol (11.29%) and carvacrol (9%) were the major components. In the O. basilicum L. cv. (autochthon) cultivar with green narrow leaves, twelve components were characterized representing 90% of the total oil, with. Linalool (48 %) and eugenol (36.09 %) as the major components. Linalool (Raguso et. al., 1999) is the dominant constituent in the two cultivars; There was no big difference between the two green cultivars with different leaf morphology in their oil content. These results suggest that further research to improve the quality of the essential oil content is necessary.

THE SURFACE WATERS THAT FLOW TO LAKE OHRID AND ROLE OF DIATOMS IN BIOLOGICAL MONITORING

International Journal of Ecosystems and Ecology Science (IJEES) (2019)

Elona Bahiti Lirika Kupe

Ohrid Lake is one of the oldest lakes in the world, formed about 2-3 million years ago.Many of lakes of the globe are about 10,000 to 45,000 thousand years old and formed during the glacial period.In an old lake, with hills and mountains that separated them from other waters, a whole collection of plants and animals is developed.Lake Ohrid is located at a height of 695m, with a surface of 358.2 km 2 and a coastline of 87.5 km.About 2/3 of the lake is in the North Macedonian part and 1/3 belongs to the Albanian side.It represents an exceptional source of water, the great biological diversity and the endemic species that are presently threatened by many factors.Most of the Ohrid Lake basin is formed by tectonic forces.At a later stage of the alpine oogenesis the holes of Ohrid, Prespa and Debarca are formed.The Ohrid Lake itself is formed on Bilisht-Korça-Debarca.As a geomorphologic characteristic of the catchment basin we mention abrasive formations (rugged rocks, bare rocks and rocks and subsoil), river formations (river valleys, river beds, erosive and accumulative terraces) karstic formations (cracks, water holes, pits and fields karstic surface as well as holes and underground holes).Biomonitoring is the use of biological indicators as assessors of environmental change.Since, chemical compounds of the rivers pass through mass flows over a short period of time, chemical monitoring gives an instantaneous water quality picture only for the sampling moment.In Albania, biological monitoring based in diatoms, for the first time is carried out in Albanian rivers (fresh water), the data are presented by Miho et al., (2005); on PhD thesis by Kupe L., (2006).After then had continued with further studies in the area of ecological (diatoms) assessment of fresh and marshes water.

Bio-monitoring of Bishtaraka Lagoon.

Research Journal of Agricultural Science (2010)

Alma Imeri Lirika Kupe Julian Shehu Alfred Mullaj Erta Dodona

Data on the trophic state of Bishtaraka Lagoon are presented. The Bishtaraka's Lagoon is located in central coastal region of Albania and exists as transitional environments between land and sea. The lagoon covers a surface ca.155 ha Level of trophic state is based on standard methods for analysis of macrophytic vegetation (15) and chlorophyll a content and other photosynthetic pigments of phytoplankton, dissolved oxygen (DO) and biological oxygen demand (BOD), Phosphor contents. Also are measured physic characteristics of waters like temperature, Ph and turbidity of water. Plant communities' evaluation is based on qualitative and quantitative characteristics and is classified through principals of Zurich-Montpellier school. Monitoring of chlorophyll a content and other photosynthetic pigments of phytoplankton, dissolved oxygen (DO) and biological oxygen demand (BOD), phosphor contents, and diatoms species are carried out during a year from April to September 2009. In Lagoon are selected four stations for samples taking. Evaluation of water trophic level is based on classification proposed by Hǻkannson (4). Oligotrophic: clear and blue water, with very low levels of nutrients and algae. Mesotrophic: slightly green water, still clear, moderate levels of nutrients and algae. Eutrophic: green and murky water, with higher amounts of nutrients and algae. Hypertrophic: supersaturated in phosphorus and nitrogen, excessive phytoplankton growth, poor water clarity. Flora of Bishtaraka Lagoon belongs to the aquatic macrophytes rooting in sediment. Two main groups are commonly distinguished: Emergent aquatic macrophytes. Reed (Phragmites australis) is often found in monospecific stands, but also mixed with Typha angustifolia, Scirpus lacustris. Submersed macrophytes. From this group, in Bishtaraka Lagoon we have registered flowering plants such as Myriophyllum spicatum and Potamogeton pectinatus. The aquatic vegetation strongly influences the light conditions, temperature, oxygen concentration, sedimentation rate and turbulence in the water body. Analyses for determination of dissolved oxygen (DO) and biological oxygen demand (BOD) are realized through Winkler method. Based on the collected data we can evaluate that Bishtaraka Lagoon is characterized by a high trophic state - eutrophic level. Trophy state of Bishtaraka lagoon in four stations in April and September is presented high eutrophy, increasing from April to September.
