Sexual Dimorphism of Testudo Tortoises from an Unstudied Population in Northeast Greece
Herpetology Notes, volume 12: 229-233 (2019) (published online on 26 January 2019) Sexual dimorphism of Testudo tortoises from an unstudied population in northeast Greece Konstantina N. Makridou1,*, Charalambos T. Thoma1, Dimitrios E. Bakaloudis1, and Christos G. Vlachos1 Abstract. Sexual dimorphism in tortoise species is prominent, but may vary geographically. Here, we investigated sexual dimorphism of Testudo hermanni and T. graeca from previously unstudied populations in northeast Greece. Females of each species illustrated higher mean values in almost all traits and exhibited better body condition than males. The longer tails and smaller plastron found in males of T. hermanni, and the wider anal notch found in males of T. graeca are believed to be linked with mating success and courtship behavior. When compared to other regions, both our species were found to be larger and heavier in most cases. Our results may be used in future comparative studies, providing additional insights for both species. Keywords. Testudo hermanni, Testudo graeca, morphometry, Scale mass index, Greece Introduction morphometry and sexual dimorphism of tortoises has been previously studied in several regions of Greece Sexual dimorphism in body size and shell shape is (Willemsen and Hailey, 1999, 2003), populations from prominent in tortoise species and has been shown to Evros district remain unstudied. Our results aim to offer be driven by natural selection (e.g. to increase female additional insights from a region where tortoises have fecundity), sexual selection (e.g. to increase male never been studied before and provide new data that reproductive success), or a combination of the two may be used in future comparative studies. -

This document has been submitted by the United States of America at the request of the Wildlife Conservation Society, Durrell Wildlife Conservation Trust, Turtle Survival Alliance, and The Turtle Conservancy, in relation to agenda item 73 on Tortoises and freshwater turtles (Testudines spp.)*. 2. This species is restricted to a limited range in northwestern Madagascar. It has been included in CITES Appendix I since 1975 and has been categorized as Critically Endangered on the IUCN Red List of Threatened Species since 2008. There has been a significant increase in the level of illegal collection and trafficking of this species to supply the high end pet trade over the last 5 years. 3. Attached please find the joint statement regarding Madagascar’s Ploughshare/Angonoka Tortoise, which is considered directly relevant to Document CoP17 Doc. 73 on tortoises and freshwater turtles. * The geographical designations employed in this document do not imply the expression of any opinion whatsoever on the part of the CITES Secretariat (or the United Nations Environment Programme) concerning the legal status of any country, territory, or area, or concerning the delimitation of its frontiers or boundaries.

Change in the Uses of Urban Public Spaces by Cairo People (With a Special Focus on Public Gardens)

Beginning with the reign of Muhammad Ali and continuing under khedive Ismail, a Haussmannian model of urbanization and gentrification prevailed. Until the 1960s and 1970s, these modernized urban spaces (found primarily in the new downtown area) can be defined as the location of a bourgeois public. In Wast el-Balad (downtown) Haussmannian architecture was a key site for the articulation of new “modern” spatial prac- tices, identities, and sociabilities. This new downtown was to provide a kind of display win- dow of Egyptian modernity. Since the 1970s the meanings, uses, and publics associated with modernist urban space have undergone a radical inversion. -

Review of Manouria impressa from Lao People’s Democratic Republic . UNEP-WCMC, Cambridge. The UNEP World Conservation Monitoring Centre (UNEP-WCMC) is the specialist biodiversity assessment of the United Nations Environment Programme, the world’s foremost intergovernmental environmental organization. The Centre has been in operat ion for over 30 years, combining scientific research with policy advice and the development of decision tools. We are able to provide objective, scientifically rigorous products and services to help decision - makers recognize the value of biodiversity and a pply this knowledge to all that they do. To do this, we collate and verify data on biodiversity and ecosystem services that we analyze and interpret in comprehensive assessments, making the results available in appropriate forms for national and internatio nal level decision -makers and businesses. To ensure that our work is both sustainable and equitable we seek to build the capacity of partners where needed, so that they can provide the same services at national and regional scales.
