In this research, the facilitation effects of spiny ( Astragalus chrysostachys Boiss) and aromatic ( Artemisia kopetdaghensis (Poljakov) Y.R.Ling) shrubs were studied on species diversity along a grazing gradient. In 2017, five sites were selected in Baharkish rangelands, Quchan, where the livestock grazing varied from low to very intense. In each site, 30 twin plots were established under a canopy of the nurse shrubs and their nearby open spaces. Density, frequency and canopy cover of all plants were measured within the plots. Species diversity were reduced by increasing the grazing intensity, but it was consistently higher under canopy. In the highest grazing intensities, species diversity was higher under the canopy of Artemisia than Astragalus ; however, opposite results were found under the high grazing intensity. In conclusion, in the areas of high grazing (livestock rest points), the aromatic species ( Artemisia ) may not be protected against livestock grazing, and spiny shrubs ( Astregalus and Acantholimon ) may still maintain their nursing effects.","PeriodicalId":31359,"journal":{"name":"Iranian Journal of Applied Ecology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45663419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study was aimed to identify suitable zones for establishing ecoparks in the central region of Isfahan province; this was done using seven effective criteria including topography, landscape, climate, rock and soil, water resources, environmental sensitivity, and accessibility. The weights of the criteria and the subcriteria were obtained using the analytic hierarchy process (AHP) with expert opinions. All layers were combined using weighted linear combination (WLC) and the land suitability maps for ecoparks were produced. After evaluating and prioritizing suitable zones, finally, the zone with an area of 85.2 hectares, which was located in the Bag Bahadoran district and adjacent to the Zayanderood River, was selected as the most suitable one due to its larger area, more access to the welfare facilities, and higher ecological potentials. Also, the results obtained from overlaying the ecopark’s land suitability map and the map of existing parks in the region suggested that Sararud coastal park, in Mobarakeh, and the coastal park, in Zarrin Shahr, can be suitable places for establishing ecopark in the region.","PeriodicalId":31359,"journal":{"name":"Iranian Journal of Applied Ecology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42000429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, by using landsat images of the years 1996 and 2016, landuse maps were classified into four classes including: agriculture, rangeland, residential areas, and rocks. Land Change Modeler (LCM) and Habitat and Biodiversity Modeler (HBM) modules in the Idrisi GIS software were used to analyze the land use changes and habitat evaluation for the prediction of the land uses status in 2016, based on the Artificial Neural Network (ANN), Markov Chain analysis and logistic regression. The results showed that most of the changes in the landscape of the region between 1996 and 2016 were related, respectively, to attrition, aggregation and creation indicators; between the years 2016 to 2041, they can be related, respectively, to the creation and dissection indicators. The habitat evaluation showed that 4.5% of the habitat was decreased in 2016, as compared to 1996. With the continuation of this trend, 6.5% of the habitat will fall in 2041, as compared to 2016. Receiver Operating Characteridtic (ROC) of the model also specified that the desirability model validity was equal to 0.9558, showing the excellent performance of logistic regression method. In general, this can be an important principle approach preventing from changes in the habitat of wild sheep to other land uses.","PeriodicalId":31359,"journal":{"name":"Iranian Journal of Applied Ecology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47163858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Habitat suitability modeling is one of the best tools used for habitat management. There are several methods for habitat suitability modeling, with each of having some different advantages and disadvantages. In this study, we used 15 modeling methods along with 9 environmental factors including Bio1, Bio2, distance to roads, distance to residential areas, distance to agricultural lands, distance to streams, the percentage of slope, geographic aspect, and NDVI to model the Persian squirrel’s habitat suitability in the forests of Luristan Province. The AUC of each model was computed and the models with an AUC higher than 0.9 were selected. Finally, the output maps resulted from the selected models were multiplied by their AUC and the average of them was considered as a combined model. In this study, Maximum Entropy, Boosted Regression Tree, Generalized Linear Model, and Random Forest were the only models with an AUC higher than 0.9. Based on the combined model, 66% of the forest areas in Luristan Province could be suitable for the Persian squirrel, of which 32.1%, 18.4%, and 15.5% have low, moderate, and high suitability, respectively. Among the 9 environmental factors used in this study, distance to roads, distance to agricultural lands and NDVI showed the highest contribution in the habitat suitability of the Persian squirrel. This study indicated that the combination of high-accuracy models could yield more reliable results, as compared to their separate use.","PeriodicalId":31359,"journal":{"name":"Iranian Journal of Applied Ecology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45193432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, sodium parameters, electrical conductivity, chloride, hydrogen bicarbonate and sodium absorption ratio (SAR) were used. Then, groundwater quality classification across the study area was carried out using agricultural water quality index (IWQI), which is based on the FAO standards. Results of IWQI varied from 40 to 80, corresponding to high and low limitations for agricultural use. It was shown that groundwater quality had declined over years from the upstream to the downstream of the basin. Furthermore, some changes in the quality index in the northern region of the study area were found to be more affected by the climate conditions of the region. In the middle and eastern territories, the surface streamflow of Zayandehroud River and agricultural activities had caused changes in the water quality. In general, in the Gavkhooni area, excessive groundwater exploitation, drought conditions and agricultural activities had reduced the groundwater quality. By reducing groundwater withdrawals and agricultural activities in areas where water is required only through water drainage, groundwater quality can be managed, even in dry years.","PeriodicalId":31359,"journal":{"name":"Iranian Journal of Applied Ecology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42649953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Habitat suitability map was generated in MaxEnt using 101 presence points and nine environmental variables, which were later inversed and used in corridor modeling. By using the circuit theory method, areas of high migration density were compared with four clusters determined in a previous study based on the least-cost model. Three main clusters with the high migration density of BBB were detected. Moreover, we identified eight insular habitat patches of the species that required urgent management actions to connect with other patches in the southeastern Iran. Circuit theory method clearly confirmed the main clusters introduced for the conservation of the BBBs in the southeastern Iran.

Seventy soil profiles and 10 climate stations data were used to produce 31 environmental maps including climate and soil maps using kriging methods. According to the results, the presence of Ferula ovina was correlated with silt percent, average annual temperature, elevation, organic matter content, soil saturation percentage and CaCO 3 content. The produced species distribution model had high accuracy, as indicated by calculated Kappa coefficient (0.79) and ROC area under curve plots (0.83).
