The effects of some environmental factors on distribution of Lonicera nummulariifolia were studied in Manesht-Ghalarang protected area in Ilam Province. Vegetation, physiographic characteristics and soil (texture, Ph, EC, SP, Cao, OC, P, N, K and bulk density, depth of 0-30 cm) was investigated in 125 plots. Totally, 166 plant species belong to 121 genus and 44 families were identified in this study area. The families of Asteraceae (21 species), Labiateae (20), Poaceae (15 species), Papilionaceae (13 species) had the highest number of plant species. Multi-variant analysis showed that Lonicera nummulariifolia had positive relationship with organic matter, nitrogen, altitude and formation of Asmary and negative relationship with lime, EC, clay and silt. Also, Amygdalus elaeagnifolia, Cotoneaster luristanica, Daphne mucronata, Rhamnus Pallasii, and Cerasus microcarpa has the most ecological similarity with L. nummulariifolia. The results can be a useful for the development of L. nummulariifolia in areas with similar ecological conditions.

Forest fire is the major disturbance that can severely destruct genetic stocks and delays evolution of the forest to reach the climax stage. In this research, the effect of fire, vegetation and soil changes from 2002 to 2013 have studied. Following the steps of determining the scope of fire using GPS, preparing a homogeneous unit map in ArcMap software and implementing a systematic random-access network of 1250 × 800 m on a digital map of the area, 15 pieces of rectangular sample of 25 × 30 meters in homogeneous units and each of the experimental treatments (fire area and control) were chosen to take 5 soil samples from depths of 0-10 and 20-10 cm and measure the number of vegetation cover. The relationship between plant species and soil properties was significant in variance analysis such as gravel and silt percentage, acidity, carbon percentage, organic matter and total nitrogen, carbon to nitrogen ratio, and response of plant species to fire with Redundancy Analysis (RDA). The results showed that the response of Rheum ribes L., Artemis aucheri Boiss, Echinops dichorus L., Pisticia atlantica Desf. and Ficus johanis Bois. were positive to the fire and the fire in the studied area has changed some of the properties of soil and vegetation.

Drought is one of the main factors of ecological potential stress due to the wide extension of the time scale and impact space. The performance of regional drought monitoring using the meteorological indicators is a challenge due to spatial distribution constraints. In present study, 168 time series images including NDVI and LST indices were used. Integrating these two indices, VSWI was used to assess near-real-time and spatial-temporal spatial drought monitoring in Gavkhoni basin during 2003 to 2014. The SPI was assigned as the basis and the feedback of satellite and meteorological indices was assessed using Pearson correlation test. The results of the study of the relationships between the mean annual values of the VSWI and SPI indices during the same period showed a value of 0.578. In order to study the significance of the indices correlation, a nonparametric Spearman correlation test was added to the study. In addition, the results of the spatio-temporal pattern of the annual VSWI, indicating a severe long-term drought in the southeastern parts of the Zayandehrud dam and the entire Gavkhoni wetland area. The adaptation of this map to the meteorological drought map indicates the efficiency of integrating NDVI and LST satellite indices in drought monitoring.

Long-term survival of Goitered gazelles in central Iran has been threatened because of isolation of existing populations and genetic threats. Effective management of these small and isolated populations needs to evaluate landscape connectivity among core habitat patches. In the present study, resistance surfaces were mapped as a function of twelve uncorrelated variables using species distribution algorithms. Given the limited empirical data of Goitered gazelle dispersal distances, we assessed different dispersal ability scenarios. Extent of core habitats, fracture zones, and dispersal corridors were identified using resistance kernel approach. Our finding showed that while gazelle population in Biduiyeh Protected Area has been isolated, there is relatively high dispersal rate among populations of Goitered gazelle in Mooteh National Park, Ghamishloo National Park, Kahyaz Protected Area, Kalmand-Bahadoran Protected Area and Kolah-Qazi National Park. Given the effect of roads and metropolises, functional connectivity between Kolah-Qazi and other populations is not possible. Based on genetic relationships and landscape connectivity results, we concluded that gazelle populations in Central Iran can be grouped into three separated subpopulations including 1- Biduiyeh P.A., 2-Kolah-Qazi N.P., and 3- gazelles in other protected areas. The obtained results show that integrated conservation management at landscape level need to be considered in maintaining gene flow among isolated and fragmented habitats.

Global warming and climate change due to increasing greenhouse gases (GHGs) concentration caused widespread concerns in the national and international societies. Carbon dioxide and methane as the most important greenhouse gases in the atmosphere account for more than about 80% of global warming due to greenhouse gases emission. In this study, Multivariate linear regression (method: enter and stepwise) was used to determine the relationship of CO2 and CH4 concentration with NDVI, LST, humidity, and temperature by GOSAT TANSO-FTS level 2 data, MODIS products (MOD13Q1 and MOD11C3), and meteorological parameters (Temperature and Humidity) in Iran. According to the results, the negative correlation among GHGs and NDVI, HUM, and HIG and the positive correlation among these gases and LST and TEM were observed in different seasons of 2013. These correlations showed concentration of carbon dioxide and methane diminished in the study area by increase in humidity, elevation and NDVI and decrease in LST. In spring, important factor in change of CO2 and CH4 was NDVI while, in other seasons climatic parameters were important.

A new method to quantify, monitore and assess ecological structures and functions is the application of graph theory. In ecology, this theory demonstrates its suitable application in assessment of ecological connectivity. Connectivity is the structural attribute of landscape which facilitates the species movement among their habitats. Using graph theory, this paper aims to assess the connectivity of habitats within an urban landscape. Therefore, firstly the graph fundamentals, the graph-based connectivity studies, various methods, software and graph-based metrics for graph modeling were discussed. Then using this theory, the habitat network of Varanus varius was modelled within the Greater Melbourne as a weighted network incorporating nodes and active links. The connectivity of adjacent habitats was assessed using pij and flux metrics. The overall connectivity of the network was assed using DCflux Eventually the nodes were prioritized based on their importance for maintenance of network connectivity. The use of method showed that majority of highly ranked patches are located on the fringes of metropolitan Melbourne. In addition, a number of important patches are located on the urban growth boundary at North, North East and East of Melbourne that is a potential conflict between conservation plans and land use planning. Due to the ease of its application and validity of results, the use of this theory and the metric DCflux is recommended to study the species habitat networks in fragmented landscapes especially urban landscapes.

Heavy metals are of most important environmental pollutants. Industrial activities and using pesticides are mainly causing environment to be polluted by these elements. This study aims to investigate the effect of air pollution on concentration of leaf heavy metals (Fe, Cu, Zn and Mn) of urban green space’s trees and their tolerance in Urmia. For this purpose, leaf samples of Acer negundo and Platanus orientalies individuals were collected in August 2013 and May 2014 from five different regions with different level of air pollution and their heavy metals concentrations were measured. Regarding to increasing of air pollution in the second year comparing to the first year, the accumulation of most elements had been increased by the tree species. In general, P. orientalies was considered as more tolerable species comparing to A. negundo due to higher accumulation even more than permissible defined threshold. Studied species, also, had lower and higher accumulation in the control and polluted places respectively, so it could be possible to use these species to differentiate between the polluted and unpolluted areas.
