Abstract

ezaei-Taleshi SA. 2014. A comparative study on plant diversity in alder (Alnus subcordata) stands of natural and plantation areas. iodiversitas 15: 39-47. Diversity index is the useful criteria for evaluating sustainability of forest ecosystems. Current study carried out in Alder (Alnus subcordata C.A. Meyer) stands that located in north forests of Iran. The aim of the study is express the plant diversity indices and positive role of the trees both natural and plantation forms. Data of Alder trees and associated species were recorded in sample plots which lay down in study area randomly. The abundance, density, percentage of frequency of each species was calculated by standard methods. The results of analysis revealed that, 47 species (21 trees and shrubs species and 26 herbaceous species) were abundant in 80 sample plots both in natural and plantations Alder stands. Whilst the results showed that the number of species in natural area (44 species) was more than plantation stands (37 species). Comparison of species distribution in different physiographical situation showed that some species such as Alnus subcordata, Parrotia persica, Rubus hyrcanus and Prunus sp. recorded in spread rang of physiographic variables as elevation, slopes and aspects. The biodiversity criteria as Shannon H’ and Simpsons D and 1/D indexes showed that they were more in natural stands than plantation areas.

Abstract

Bazdid Vahdati F, Saeidi Mehrvarz Sh, Naqinezhad A, Gholizadeh H. 2014. How plant diversity features change across ecological species groups? A case study of a temperate deciduous forest in northern Iran. Biodiversitas 15: 31-38. Species diversity is one of the most important indices for evaluating the stability and productivity of forest ecosystems. The aim of this research was to recognize ecological species groups and to determine the relationship between environmental variables and the distribution of ecological species groups. For this purpose, 25 400-m 2 relevés were sampled using the Braun-Blanquet method. Vegetation was classified using modified Two-Way Indicator Species Analysis (TWINSPAN) and resulted in three ecological species groups. Different species diversity indices were applied to quantify diversity of these species groups. ANOVA and Duncan’s tests indicated that all species and environmental variables except altitude changed significantly across the species groups. The results also showed that the group located in the northern aspect and on low slopes had the highest diversity indices compared with groups located in dry aspects and on high slopes. In reality, abundant precipitation (northern aspect) and soil enrichment (low slopes) are principal factors that provide suitable conditions for plant growth and species diversity. Thus, the study of diversity changes in ecological species groups can result in an ecologically precise perspective for managing forest ecosystems.

Abstract

Ahmadi A, Kavosi MR, Soltanloo H. 2014. Zelkova carpinifolia reservoir from Hyrcanian Forests, Northern Iran, a new sacrifice of Ophiostoma novo-ulmi. Biodiversitas 15: 48-52. Zelkova carpinifolia belongs to the Ulmaceae. It is the only species from Zelkova genus that has been distributed and is native to Iranian forests. This tree species is one of the valuable species that is comprised of endangered plants. Nevertheless, the most of reservoirs of this species have been faced to problems that fungal disease is one of the important and lethal disturbance. This study was conducted to identify the main disturbance which has been resulted in Z. carpinifolia decadence in Daland forest reservoir, North of Iran. The study has ensured that O. novo-ulmi is the fungal pathogen in this forest reservoir. It can be reminded that this pathogen had been previously found in Ulmus genus which has been created devastating event in these noteworthy reservoirs. Some symptoms which were observed in field comprising flagging and wilting of leaves. Bark beetle galleries and occlusion of xylem vessels were the other evidence of fungal disease. In light of laboratory results, the fungi colony was fluffy, light-colored and fast-growing. The different shapes of fungi growth like white fibrous and flower shape or dark petaloid shape were observed. Mean colony diameters of O. novo-ulmi were 3.72 ±0.16 mm/day in the dark at 20 °C. Simultaneously, Microscopic analysis of sexual and asexual systems of O. novo-ulmi using a light microscope, a stereo microscope, and a scanning electron microscope revealed that it had morphological features of sporothix, pesotum, yeast-like and perithecium synanon morphology.

Abstract

Karami A, Sefidi K, Feghhi J. 2014. Structure and spatial pattern of land uses patches in the Zagros Mountains region in the west of Iran. Biodiversitas 15: 53-59. Landscape ecology as a new interdisciplinary science, concepts, theories and methods provides for evaluation and management of land. Quantification of landscape patterns has key role in the interpretation and modeling of spatial and chronically variation of land uses. This study carried out in the Zagros vegetative region in the west of Iran to quantify structure and spatial pattern of land uses and forest fragmentation in the Zagros Mountains region. The mosaic analysis method was used for quantifying landscape metrics. Totally 2783 land use patches were recorded in the study area. The most of the patches were agricultural area and the lowest number of patches recorded for rivers. Diversity indices analysis showed agricultural land use has highest diversity in comparing with other land uses. Rangeland use has distributed in the central region of the study area. Despite the high density agriculture and rangeland a lot of potentials there are two conversions this land as a sustainable ecosystem (forests, agriculture integrated, and rangelands), that can be by applying as an appropriate method in management and control policies and converting artificial land uses to the natural or semi natural land uses according to the advantages of such land uses in view of sustainability. We conclude that fragmentation of natural land uses such forest and rangelands should be reducing and maintain large patches of natural vegetation to sustainable land management in this region.

Abstract

Khan MS, Pant A. 2014. Conservation status and distribution pattern of the Indus River Dolphin in River Beas, India. Biodiversitas 15: 75-79. Decline in the populations of Indus River Dolphins Platanista gangetica minor throughout its range of distribution and a perception that it is a 'keystone species' for riverine ecosystem stirred the idea of proposed study. Deficiency of baseline data on its distribution and ecology is a major constraint that this (only known sub-population in India) species’ conservation is facing in the country. Thus to ascertain its conservation status and distribution pattern, the study was conducted between December 2010 to June 2012. During the study, three schools of dolphins have been identified, one each along Beas bridge-Gagdewal; Baguwal-Dhunda and Karmowala-Harike that comprised of adult, sub-adult and calves. The occurrence dolphins was found attributed to preferred habitat features such as deep pools, slow water current, abundant prey base and low disturbance.

Abstract

Mollaei-Darabi S, Kooch Y, Hosseini SM. 2014. Reaction and fractal description of soil bio-indicator to human disturbance in lowland forests of Iran. Biodiversitas 15: 60-66. Earthworms are expected to be good bio-indicators for forest site quality. The deforestation of land into another function could changes the soil features that could effect on earthworm population. This study was conducted to understand the changes of soil functions, resulting from exploitive management using some soil features and their fractal dimensions. Two sites were selected, consisting of an undisturbed forest site (DS) in lowland part of Khanikan forests located in Mazandaran province, north of Iran. Within each site 50 soil samples were obtained from 0-30cm depth along two sampling lines with 250 meter length for each. Deforestation brought a lower soil quality in the sites under the study. Decreasing silt, clay, moisture, pH, carbon to nitrogen ratio, available Ca, earthworm density and biomass, increasing bulk density and sand were few outcomes of the deforestation. Except for clay, the deforestation affect on fractal dimension of soil features. The fractal dimension of bulk density, silt, moisture, pH, earthworm density and biomass were decreased imposed by deforestation. Our results suggest that deforestation should be regarded as an effective factor on variability of soil features that are tied to forest ecology. This is significant for evaluating forest management policies and practices with respect to effects on soil and also for the use of soils as indicators, especially earthworms as bio-indicator, of forest ecosystems.

Abstract

Reyahi-Khoram M, Rizvandy M, Reyahi-Khoram R. 2014. The threats on the biodiversity of Bisotun Wildlife Refuge and Bisotun Protected Area (BPA & BWR) in the west region of Iran. Biodiversitas 15: 67-74. Nature is necessary for the preservation of species and biodiversity richness; as a result, it has been protected for thousands of years. Bisotun Protected Area and Bisotun Wildlife Refuge (BPA & BWR) with about 95000 hectares is located in Kermanshah province in the west of Iran. The object of this study is to determine the physical properties and analyze the constraints that threaten the BPA & BWR. This research was conducted during the period from May, 2011 to November, 2012 in BPA & BWR. In this research, various animal and plant species were recognized through documentary analysis and also directs field observations. The obtained result indicates that major threats have occurred in biodiversity and ecosystem of BPA & BWR during 1980-2010. During these years, the study area has completely failed and lost some of its biological diversity. Limiting factors that affect wildlife population growth including destruction and conversion of habitats, unauthorized hunting and high frequency presence of animal and human, have influenced the restoration potential of wildlife, the habitats and other conservation areas.

Abstract

Kukreti M, Bhatt D. 2014. Birds of Lansdowne forest division and adjacent suburban landscapes, Garhwal Himalayas, Uttarakhand, India: Community structure and seasonal distribution. Biodiversitas 15: 80-88. This study of bird species diversity aims at understanding the distribution patterns and structures of avifauna of the two forest ranges and adjoining suburban areas of the Lansdowne forest division, Uttarakhand, India. Data on the abundance and richness were collected by standardized Verner’s line transect method for two years (January 2011 to December 2012). A total of 216 species were recorded from the study area. Family Muscicapidae with 30 species was found to be dominant in the forest habitats, while family Corvidae with 10 species was found to be dominant in the suburban areas. Results indicate that the forests had more complex bird community structure in terms of higher species richness (8.95 vs 8.59), higher species diversity (0.085 vs 0.080) and more rare species (74 vs 15) as compared to urban habitats. Bird species richness (BSR) and bird species diversity (BSD) fluctuated across seasons but not across habitat types. In order to sustain avian diversity, it is recommended that anthropogenic disturbance should be reduced and traditional agroforestry should be developed in the study area.
