Abstract

The charcoal disease agents, Biscogniauxia mediterranea and Obolarina persica are two latent, ascomycetous oak pathogens in the Middle Eastern Zagros forests, where they have devastating effects, particularly during drought. Under greenhouse conditions, we investigated the effects of the two charcoal disease agents individually and in combination with drought on survival, growth, foliar gas-exchange, pigment content, oxidative stress and the antioxidant response of Quercus infectoria and Q. libani, two of the dominant tree species in this region. Commonly, the strongest negative effects emerged in the drought–pathogen interaction treatments. Q. infectoria showed less severe lesions, higher survival, more growth, and less leaf loss than Q.

Abstract

Taxus baccata is an indigenous and valuable species in the Hyrcanian Forests. According to recent studies, the presence of this species in the distribution areas is declining; therefore, preserving and restoring this valuable species is of great importance. One of the most strategies for conservation and rehabilitation of valuable species is identification of its potential distribution and prioritization of areas with potential presence of this species using species distribution models. This study aims to prioritize the suitable habitats for preservation and restoration of yew in the Hyrcanian forest. In this study, the Boosted Regression Tree (BRT) algorithm was used to model the distribution of yew species in relation to climatic, edaphic

Abstract

Zarde-Kija mushroom(Cantharellus alborufescens) is one of the edible mushrooms belong to the Cantharellaceae family. It is widely distributed in the northern forests of Iran and is desirable for local residents in these areas. Despite the economic importance of this genus, litthe is known about their habitat requirements. This study was conducted to identify the environmental factors affecting the distribution of this mushroom in a plain forest of Noor city (Mazandaran province, northern Iran) with 120 ha area. For this purpose, 20 pair plots (20 m ? 20 m) with at least 100 m distance were established (20 plots with Cantharellus and 20 non-Cantarellus plots). To analyze the species-environment relationship (soil characteristics), three grou

Journal PapersCatena , Volume 178 , 2019 July 1, {Pages 32-39 }

Abstract

The properties of litter and soil, which are probably influenced by vegetation traits, have an effect on the fractions of C and N and ultimately global warming. In this study, litter and soil samples were collected from representative forestlands, including a mixed natural forest dominated by hornbeam‑ironwood and tree plantations of ash, maple, cypress and pine which are situated in a temperate area of Northern Iran. Main litter characteristics, soil aggregation and fractions of C and N were studied. Pine had the highest values of litter thickness (14.46 cm), C (60.31%) and C/N ratio (81.77 and 20.28 for litter and soil, respectively). However, litter N (2.20%), micro aggregates of total soil (39.75%), aggregate stability (73.86%) and

Abstract

The Hyrcanian climate in the northern parts of Iran has warmed over the past 50?years, but the impacts on plant species are unknown. As the longest-lived tree in the Hyrcanian forest, English yew, Taxus baccata L., is a rare and endangered species in the forests along the Iranian coasts of the Caspian Sea, which is likely affected by climate change. This paper explores the current and future distribution of this species, using four species distribution models. In order to project the effect of climate change on the distribution of English yew by 2050 and 2070, output from the HadGEM2-ES climate model was used for two RCPs scenarios (2.6 and 8.5). The results showed a good accuracy of all the models for the distribution of this

Abstract

BACKGROUND: Differentiating ischemic from non-ischemic functional mitral regurgitation(FMR) in patients with cardiomyopathy is important in terms of the therapeutic decisionmaking and prognosis, but might be clinically challenging. In this study, the deformation of mitral valve (MV) indices in the prediction of the etiology of FMR was assessed using 2D transthoracic and tissue Doppler echocardiography. METHODS: This case-control study was conducted from April 2015 to January 2016 in Imam Reza Hospital in Mashhad, Iran. The participants consisted of 40 patients with ischemic cardiomyopathy (ICM) and 22 with non-ischemic dilated cardiomyopathy (DCM) who referred to the heart failure clinic. Transthoracic echocardiography was performed using t

Abstract

Nanoparticles can influence key physiological processes including seed germination, photosynthesis, and thereby plant growth and yield. Despite several studies have addressed the effects of nanoparticles on crops, data for woody plant species is still scarce. In this report, the effects of silicon dioxide nanoparticles (SiO2 NPs) application, as potentially toxic elements, on physiological performance of 1-year-old woody plants, namely, hawthorn (Crataegus aronia L.) and mahaleb (Prunus mahaleb L.), were evaluated. Plants were irrigated with different concentrations of SiO2 NPs (0, 10, 50, and 100?mg?L−1) for 45 days, and gas exchange parameters, relative water content (RWC), xylem water potential, growth, biomass allocation, a

Abstract

BACKGROUND: Vitamin D deficiency is a prevalent condition in Iran and previous studies have shown that a low level of serum vitamin D is related to low ankle-brachial index (ABI). In the present study, the relationship of the serum level of vitamin D with ABI, as an index for atherosclerosis of peripheral arteries, was evaluated. METHODS: In this cross-sectional study, data on 91 patients with metabolic syndrome (Mets) from the Isfahan Cohort Study (ICS) were analyzed in order to evaluate the association between serum 25 (OH) vitamin D level and ABI. The participants were divided into two groups; group A with desirable serum vitamin D level and group B with abnormal serum vitamin D level. ABI was measured and compared between these groups.

Abstract

Acer hyrcanum is a rare maple distributed mainly in the Hyrcanian Mountain forests of Iran and in other parts of western Asia. Its high potential for use in forest rehabilitation programmes is limited due to lack of knowledge about its seed germination requirements. In the present study, we aimed to investigate the seed dormancy and germination requirements of this rare maple. Mature seeds require at least eight weeks of cold moist stratification to overcome dormancy and initiate seed germination, however, 16 weeks of cold stratification was found to be optimum to achieve > 95% germination. GA3 shortened the cold stratification period and enhanced germination but failed to substitute for the cold stratification requirement. Pericarp removal

Abstract

Coronary artery disease (CAD) is a multifactorial condition (1). It has been known as a disease with high mortality and morbidity rates worldwide (2). When the perfusion and function of the heart are at risk, percutaneous coronary intervention (PCI) may be used for patient management (3). Coronary artery bypass graft (CABG) is the effective surgical technique in multivessel coronary disease (4). In the US only, the prevalence of CABG is more than 120,000 patients per year (5). According to patients' conditions and their risk factors, beating heart cardiopulmonary bypass (beating heart CPB) or off-pump technique may be chosen (3) Although hyperlipidemia (HLP), diabetes (DM), and hypertension (HTN) are known as familial and cardiac risk facto
