The effect of environmental pollutions on phytochemical parameters and antioxidant activity of Quince, Apple, and Mulberry fruits
Human actions are causing the slow killing of plant and animal species in nature through toxic pollution due to industrial and technological advancement in recent decades. To reveal metal toxicity, the effects of industrial pollution on phytochemical parameters of Malus domestica, Cydonia oblonga and Morus alba were determined. So, plants were collected from east of […]
Assessment of socio-economic factors and plant agrobiodiversity (Case study: Kashan city, Iran)
Conservation of agrobiodiversity is essential to achieve sustainable agricultural systems. A study was conducted in Kashan city in Iran in 2013 to assess the effects of socio-economic factors on agrobiodiversity Six villages were chosen so that they provided a uniform distribution over the region. Data were gathered using semi-structured questionnaires and explored using stepwise linear […]
Mortality of red mullet Mullus barbatus barbatus (Linnaeus., 1758) in Western Algerian coasts
Red mullet Mullus barbatus barbatus (Linnaeus, 1758) is a demersal species. It is an important commercial fish in Mediterranean coasts of Algeria, as a target of trawl fishery. Annual landings of this species are approximately 17.3% of the total landings of demersal fishes species (DPRH, 2010). Of a total of 1679 specimens, 1150 females and […]
Assessment of the environmental condition of mountainous streams in macrohabitat scale (Case Study: Delichai Stream in Tehran, Iran)
In the present research environmental condition of a mountainous stream in macro habitat scale is investigated, and Delichai mountainous stream is selected as the pattern stream for investigation. At first hydrological and hydraulic approaches in the study stream were investigated. In the next step, physical habitat in macro scale was evaluated. Based on the results […]
Diversity and distribution of butterflies in the open and close canopy forests of Cadaclan, San Fernando La union botanical garden of North Luzon, the Philippines
Butterflies were sampled in Cadaclan, San Fernando La Union Botanical Garden (LUBG) of North Luzon to provide information on species-level diversity trend and distribution of butterflies on the open and close canopy portion of the dipterocarp forest from 2012-2014 using field transect method Species accumulation curve shows that additional sampling is needed for the possible […]
Importance of protected areas for biodiversity conservation in south Côte d’Ivoire: case of National Floristic Center of F.H.B University of Abidjan
To show the impact of human activity on biodiversity in humid equatorial region, termites, insects recognized as bio-indicators of climate change in the tropics were studied in two habitats: The National Center for Floristic (CNF), a preserved habitat for 51 years and the Campus of Cocody (CC), a strongly anthropic environment. Termites were sampled using […]
Multivariate analysis of the ecological data of natural vegetation of Lahore district
A study of vegetation and different parameters of soil and water of Lahore District was carried out in this investigation. Vegetation data was evaluated by using multivariate analysis methods i.e., Tow-way Indicator Species Analysis (TWINSPAN) and Canonical Correspondence Analysis (CCA). About seventy eight species belonging to thirty seven families were recorded from forty quadrats in […]
Effect of some environmental factors on plant distribution using LFA method (Case study: Valuyeh summer rangeland of Mazandaran province)
The main objective of this study is to survey the effective environmental factors on distribution plant species using LFA method in north and south of Valuyeh summer rangeland, Iran. The both aspects in height of 1600 to 2200 m used the 14 transects 50 meters and 70 plots 1×1 along transect and in the direction […]
Analysis of diversity among wild gladiolus (Gladiolus sp.) accessions using morphological traits
In Tunisia, the local germplasm of wild Gladiolus have been currently damaged by severe genetic erosion, pollution, urbanization and bad farming practices. The aim of the present study was to prospect, collect and assess morphologically 15 accessions of this species from several areas in Tunisia. The identification and characterization of 300 individuals (20 samples per […]
Dynamics of growth and phytomass allocation in seedlings of Pistacia atlantica desf. versus Pistacia vera L. under salt stress
Salinity represents a major environmental constraint which can severely limit plant establishment in the arid and semi-arid areas in Tunisia. The present work was carried out to study the response of Pistacia vera L. and Pistacia atlantica Desf. seedlings to salt stress. Evaluation of salinity effects on both species was investigated using five increasing NaCl […]
