  • Preliminary Analysis of Correlated Evolution of Morphology and Ecological Diversification in Lacertid Lizards
    Butll. Soc. Cat. Herp., 19 (2011) Preliminary analysis of correlated evolution of morphology and ecological diversification in lacertid lizards Fèlix Amat Orriols Àrea d'Herpetologia, Museu de Granollers-Ciències Naturals. Francesc Macià 51. 08402 Granollers. Catalonia. Spain. [email protected] Resum S'ha investigat la diversitat morfològica en 129 espècies de lacèrtids i la seva relació amb l'ecologia, per mitjà de mètodes comparatius, utilitzant set variables morfomètriques. La mida corporal és la variable més important, determinant un gradient entre espècies de petita i gran mida independentment evolucionades al llarg de la filogènia dels lacèrtids. Aquesta variable està forta i positivament correlacionada amb les altres, emmascarant els patrons de diversitat morfològica. Anàlisis multivariants en les variables ajustades a la mida corporal mostren una covariació negativa entre les mides relatives de la cua i les extremitats. Remarcablement, les espècies arborícoles i semiarborícoles (Takydromus i el clade africà equatorial) han aparegut dues vegades independentment durant l'evolució dels lacèrtids i es caracteritzen per cues extremadament llargues i extremitats anteriors relativament llargues en comparació a les posteriors. El llangardaix arborícola i planador Holaspis, amb la seva cua curta, constitueix l’única excepció. Un altre cas de convergència ha estat trobat en algunes espècies que es mouen dins de vegetació densa o herba (Tropidosaura, Lacerta agilis, Takydromus amurensis o Zootoca) que presenten cues llargues i extremitats curtes. Al contrari, les especies que viuen en deserts, estepes o matollars amb escassa vegetació aïllada dins grans espais oberts han desenvolupat extremitats posteriors llargues i anteriors curtes per tal d'assolir elevades velocitats i maniobrabilitat. Aquest és el cas especialment de Acanthodactylus i Eremias Abstract Morphologic diversity was studied in 129 species of lacertid lizards and their relationship with ecology by means of comparative analysis on seven linear morphometric measurements.

Grismer2,9 Submitted March 3, 2018 The National University of Mongolia, the Mongolian State University of Education, the University of Nebraska, and the University of Kansas conducted four collaborative expeditions between 2010 and 2014, resulting in ac- counts for all species of lacertid and agamid, except Phrynocephalus kulagini. These expeditions resulted in a range extension for Eremias arguta and the collection of specimens and tissues across 134 unique localities. In this paper we summarize the species of the Agamidae (Paralaudakia stoliczkana, Ph. hispidus, Ph. helioscopus, and Ph. versicolor) and Lacertidae (E. argus, E. arguta, E. dzungarica, E. multiocellata, E. przewalskii, and E. vermi- culata) that were collected during these four expeditions. Further, we provide a summary of all species within these two families in Mongolia. Finally, we discuss issues of Wallacean and Linnaean shortfalls for the herpetofauna of the Mongolian Gobi Desert, and provide future directions for studies of community assemblages and population genetics of reptile species in the region.

(Received December 17, 2004; accepted in revised form July 5, 2005) Abstract—We examined the fluvial geochemistry of the Huang He (Yellow River) in its headwaters to determine natural chemical weathering rates on the northeastern Qinghai-Tibet Plateau, where anthropogenic impact is considered small. Qualitative treatment of the major element composition demonstrates the dominance of carbonate and evaporite dissolution. Most samples are supersaturated with respect to calcite, 87 86 dolomite, and atmospheric CO2 with moderate (0.710–0.715) Sr/ Sr ratios, while six out of 21 total samples have especially high concentrations of Na, Ca, Mg, Cl, and SO4 from weathering of evaporites. We used inversion model calculations to apportion the total dissolved cations to rain-, evaporite-, carbonate-, and silicate-origin. The samples are either carbonate- or evaporite-dominated, but the relative contributions of the ϫ 3 four sources vary widely among samples.

With the accomplishment of the first national geographic condition census, the frequent monitoring has begun. The classification indicators of the census and monitoring data are highly correlated with Technical Criterion for Ecosystem Status Evaluation released by Ministry of Environmental Protection in 2015. Based on three years’ geographic conditions data (2014-2016), Landsat-8 images and thematic data (water resource, pollution emissions, meteorological data, soil erosion, etc.), a multi-years and high-precision eco-environment status evaluation and spatiotemporal change analysis of Qinghai province has been researched on the basis of Technical Criterion for Ecosystem Status Evaluation in this paper. Unlike the evaluation implemented by environmental protection department, the evaluation unit in this paper is town rather than county. The evaluation result shows that the eco-environment status in Qinghai is generally in a fine condition, and has significant regional differences.

  • Report on Domestic Animal Genetic Resources in China
    Country Report for the Preparation of the First Report on the State of the World’s Animal Genetic Resources Report on Domestic Animal Genetic Resources in China June 2003 Beijing CONTENTS Executive Summary Biological diversity is the basis for the existence and development of human society and has aroused the increasing great attention of international society. In June 1992, more than 150 countries including China had jointly signed the "Pact of Biological Diversity". Domestic animal genetic resources are an important component of biological diversity, precious resources formed through long-term evolution, and also the closest and most direct part of relation with human beings. Therefore, in order to realize a sustainable, stable and high-efficient animal production, it is of great significance to meet even higher demand for animal and poultry product varieties and quality by human society, strengthen conservation, and effective, rational and sustainable utilization of animal and poultry genetic resources. The "Report on Domestic Animal Genetic Resources in China" (hereinafter referred to as the "Report") was compiled in accordance with the requirements of the "World Status of Animal Genetic Resource " compiled by the FAO. The Ministry of Agriculture" (MOA) has attached great importance to the compilation of the Report, organized nearly 20 experts from administrative, technical extension, research institutes and universities to participate in the compilation team. In 1999, the first meeting of the compilation staff members had been held in the National Animal Husbandry and Veterinary Service, discussed on the compilation outline and division of labor in the Report compilation, and smoothly fulfilled the tasks to each of the compilers.

    REVISED DRAFT EXPERIENCES WITH INTER BASIN WATER TRANSFERS FOR IRRIGATION, DRAINAGE AND FLOOD MANAGEMENT ICID TASK FORCE ON INTER BASIN WATER TRANSFERS Edited by Jancy Vijayan and Bart Schultz August 2007 International Commission on Irrigation and Drainage (ICID) 48 Nyaya Marg, Chanakyapuri New Delhi 110 021 INDIA Tel: (91-11) 26116837; 26115679; 24679532; Fax: (91-11) 26115962 E-mail: [email protected] Website: http://www.icid.org 1 Foreword FOREWORD Inter Basin Water Transfers (IBWT) are in operation at a quite substantial scale, especially in several developed and emerging countries. In these countries and to a certain extent in some least developed countries there is a substantial interest to develop new IBWTs. IBWTs are being applied or developed not only for irrigated agriculture and hydropower, but also for municipal and industrial water supply, flood management, flow augmentation (increasing flow within a certain river reach or canal for a certain purpose), and in a few cases for navigation, mining, recreation, drainage, wildlife, pollution control, log transport, or estuary improvement. Debates on the pros and cons of such transfers are on going at National and International level. New ideas and concepts on the viabilities and constraints of IBWTs are being presented and deliberated in various fora. In light of this the Central Office of the International Commission on Irrigation and Drainage (ICID) has attempted a compilation covering the existing and proposed IBWT schemes all over the world, to the extent of data availability. The first version of the compilation was presented on the occasion of the 54th International Executive Council Meeting of ICID in Montpellier, France, 14 - 19 September 2003.
