Cryptic Speciation Patterns in Iranian Rock Lizards Uncovered by Integrative Taxonomy
Cryptic Speciation Patterns in Iranian Rock Lizards Uncovered by Integrative Taxonomy Faraham Ahmadzadeh1,2*, Morris Flecks2, Miguel A. Carretero3, Omid Mozaffari4, Wolfgang Bo¨ hme2,D. James Harris3, Susana Freitas3, Dennis Ro¨ dder2 1 Department of Biodiversity and Ecosystem Management, Environmental Sciences Research Institute, Shahid Beheshti University, Tehran, Iran, 2 Zoologisches Forschungsmuseum Alexander Koenig, Bonn, Germany, 3 Centro de Investigac¸a˜o em Biodiversidade e Recursos Gene´ticos, Universidade do Porto, Vaira˜o, Porto, Portugal, 4 Aria Herpetological Institute, Tehran, Iran Abstract While traditionally species recognition has been based solely on morphological differences either typological or quantitative, several newly developed methods can be used for a more objective and integrative approach on species delimitation. This may be especially relevant when dealing with cryptic species or species complexes, where high overall resemblance between species is coupled with comparatively high morphological variation within populations. Rock lizards, genus Darevskia, are such an example, as many of its members offer few diagnostic morphological features. Herein, we use a combination of genetic, morphological and ecological criteria to delimit cryptic species within two species complexes, D. chlorogaster and D. defilippii, both distributed in northern Iran. Our analyses are based on molecular information from two nuclear and two mitochondrial genes, morphological data (15 morphometric, 16 meristic and four categorical characters) and eleven newly calculated spatial environmental predictors. The phylogeny inferred for Darevskia confirmed monophyly of each species complex, with each of them comprising several highly divergent clades, especially when compared to other congeners. We identified seven candidate species within each complex, of which three and four species were supported by Bayesian species delimitation within D. -

Anderson1 Abstract Background: The majority of parthenogenetic vertebrates derive from hybridization between sexually reproducing species, but the exact number of hybridization events ancestral to currently extant clonal lineages is difficult to determine. Usually, we do not know whether the parental species are able to contribute their genes to the parthenogenetic vertebrate lineages after the initial hybridization. In this paper, we address the hypothesis, whether some genotypes of seven phenotypically distinct parthenogenetic rock lizards (genus Darevskia) could have resulted from back-crosses of parthenogens with their presumed parental species. We also tried to identify, as precise as possible, the ancestral populations of all seven parthenogens. Results: We analysed partial mtDNA sequences and microsatellite genotypes of all seven parthenogens and their presumed ansectral species, sampled across the entire geographic range of parthenogenesis in this group. Our results confirm the previous designation of the parental species, but further specify the maternal populations that are likely ancestral to different parthenogenetic lineages. Contrary to the expectation of independent hybrid origins of the unisexual taxa, we found that genotypes at multiple loci were shared frequently between different parthenogenetic species. The highest proportions of shared genotypes were detected between (i) D. -

The New Mode of Thought of Vertebrates' Evolution
etics & E en vo g lu t lo i y o h n a P r f y Journal of Phylogenetics & Kupriyanova and Ryskov, J Phylogen Evolution Biol 2014, 2:2 o B l i a o n l r o DOI: 10.4172/2329-9002.1000129 u g o y J Evolutionary Biology ISSN: 2329-9002 Short Communication Open Access The New Mode of Thought of Vertebrates’ Evolution Kupriyanova NS* and Ryskov AP The Institute of Gene Biology RAS, 34/5, Vavilov Str. Moscow, Russia Abstract Molecular phylogeny of the reptiles does not accept the basal split of squamates into Iguania and Scleroglossa that is in conflict with morphological evidence. The classical phylogeny of living reptiles places turtles at the base of the tree. Analyses of mitochondrial DNA and nuclear genes join crocodilians with turtles and places squamates at the base of the tree. Alignment of the reptiles’ ITS2s with the ITS2 of chordates has shown a high extent of their similarity in ancient conservative regions with Cephalochordate Branchiostoma floridae, and a less extent of similarity with two Tunicata, Saussurea tunicate, and Rinodina tunicate. We have performed also an alignment of ITS2 segments between the two break points coming into play in 5.8S rRNA maturation of Branchiostoma floridaein pairs with orthologs from different vertebrates where it was possible. A similarity for most taxons fluctuates between about 50 and 70%. This molecular analysis coupled with analysis of phylogenetic trees constructed on a basis of manual alignment, allows us to hypothesize that primitive chordates being the nearest relatives of simplest vertebrates represent the real base of the vertebrate phylogenetic tree. -

Given its climatic and geological conditions, Iran has multiple geosites of novel geological phenomena such as the biggest salt cave of the world, the largest Kaluts of the world, beautiful mud volcanos and… If, in an area, there are several geosites with historic, cultural works and different living natures (ecosystems), that area is called "geopark". Naturally, these regions are Iran's geotourism potentials. Attribution of "geosite" and "geopark" to each region requires such necessary infrastructures to be provided as efficient management, training of local individuals, tourist attraction based on education of geological-recreational concepts and protection of phenomena. Given numerous talents of Iran in this field, this research, after providing theoretical concepts, introduces and describes the features of those regions which are potentially ready to become geosite or geopark, and provides suggestions for geotourism development and achieving the above goals. Certainly, through providing the necessary infrastructures, a long step will be taken towards presenting invaluable geological heritage of Iran to geotourism enthusiasts in the world. -
Using Tolerated Risk for Solving Hazardous Material Routing Problem by Preemptive Goal Programming Approach
Proceedings of the 2016 International Conference on Industrial Engineering and Operations Management Kuala Lumpur, Malaysia, March 8-10, 2016 Using Tolerated Risk for Solving Hazardous Material Routing Problem by Preemptive Goal Programming Approach Abbas Mahmoudabadi Director, Master Program in Industrial Engineering MehrAstan University Astaneh-Ashrafieh, Gilan, Iran [email protected] Hassan Abdoos Deputy of Traffic Safety Department Road Maintenance and Transport Organization Tehran, Iran [email protected] Roozbeh Azizmohammadi Department of Industrial Engineering, Payame Noor University, Iran [email protected] Abstract— Route determination for hazardous material (Hazmat for short) transportation is a main concern in Hazmat management in which transport risk and cost are considered as the main attributes. The pre-defined priorities for risk and cost cause different mathematical models developed to determine the best routes which are not necessarily the shortest paths. In this paper, a tolerated risk usage is utilized to develop mathematical model for selecting the best route for carrying hazardous materials according to risk and path distance. Mathematical model has been developed using preemptive goal programming approach in which transport risk is considered more important than distance at the first step for developing model and route distance is minimized subject to pre-defined risk tolerance at the second stage. Experimental data including eighty-nine nodes and one- hundred and one links in a real network has been selected for numerical analysis and results have been discussed. Results revealed that there are some alternative routes when risk tolerance is getting to be increased or long distance paths used for hazardous materials transportation. In addition, using tolerated risk can satisfy both national/local authorities in hazmat management and transport companies as well. -

Parthenogenetic lizards of the genus Darevskia emerged as a result of the hybridization of bisexual parental species. However, uncertainty remains about the mechanisms of the co-existence of these forms. The geographical parthenogenesis hypothesis suggests that unisexual forms can co-exist with their parental species in the “marginal” habitats. Our goal is to investigate the influence of environmental factors on the formation of ecological niches and the distribution of lizards. For this reason, we created models of species distribution and ecological niches to predict the potential geographical distribution of the parthenogenetic and its parental species. We also estimated the realized niches breadth, their overlap, similarities, and shifts in the entire space of predictor variables. We found that the centroids of the niches of the three studied lizards were located in the mountain forests. -

This study aimed to determine the measles incidence risk, to conduct spatial mapping of annual measles incidence, and to assess the transition threat in different districts of Iran. Methods: A historical cohort study with retrospective data was conducted. The measles surveillance data containing 14 294 cases suspected of having measles in Iran were analyzed during 2014-2016. WHO Measles Programmatic Risk Assessment Tool was applied to calculate and map the incidence of measles in each district, to determine the annual incidence rate, and to conduct spatial threat assessment risk. Threat assessment was measured based on factors influencing the exposure and transmission of measles virus in the population. The annual measles incidence rate and spatial mapping of incidence in each Iranian district was conducted by Measles Programmatic Risk Assessment Tool. Data were analyzed by descriptive statistics in Excel 2013 and Arc GIS 10.3. Results: Of 14 294 suspected cases, 0.6% (CI 95%: 0.599-0.619) were identified as clinically compatible measles, 0.280 (CI 95%: 0.275-0.284) as confirmed rubella, 0.52% (CI 95%: 0.516-0.533) as epi-linked measles, 4.6% (CI 95%: 0.450-0.464) as lab-confirmed measles, and 94% (CI 95%: 93.93-94.11) were discarded. -
