Shell Size Differences In Helix Lucorum Linnaeus, 1758 (Mollusca: Gastropoda) Between Natural And Urban Environments, Levan Mumladze Jan 2013

Shell Size Differences In Helix Lucorum Linnaeus, 1758 (Mollusca: Gastropoda) Between Natural And Urban Environments, Levan Mumladze

Turkish Journal of Zoology

Helix lucorum Linnaeus, 1758 is a large helicid snail widespread in Georgia. While its occurrences are mainly associated with human activity, it is frequently impacted by strong direct pressure, which could cause local extinctions of populations. Instead, H. lucorum populations in anthropogenic landscapes are usually dense and apparently well adapted. Morphometric studies were carried out on 12 populations from both anthropogenic and more natural habitats in a wide range of altitudes and climatic regimes in Georgia to investigate the effects of human pressure. Populations in more anthropogenic habitats have smaller adult shells independently of any effects of climate, altitude, or …

A New Hemiscorpius Peters, 1861 (Scorpiones: Hemiscorpiidae) From Southwestern Iran, Ayşegül Karataş, Muhammed Mouradi Gharkheloo Jan 2013

A New Hemiscorpius Peters, 1861 (Scorpiones: Hemiscorpiidae) From Southwestern Iran, Ayşegül Karataş, Muhammed Mouradi Gharkheloo

Turkish Journal of Zoology

A new Hemiscorpius species, H. kashkayi sp. nov., is described from the Khuzestan and Ahwaz region in southwestern Iran. H. kashkayi is related to H. persicus Birula, 1903, known from Baluchestan in eastern Iran, which does not show sexual dimorphism between males and females, like H. kashkayi. These 2 species differ from all other Iranian Hemiscorpiidae species in having no sexual dimorphism. H. kashkayi is distinguished from H. persicus by its relatively short and well-developed stout metasoma and pedipalp segments, less developed patellar process, and carapacial and mesosomal carination.

Microstonyx (Suidae, Artiodactyla) From The Upper Miocene Of Hayranlı-Haliminhanı, Turkey, Jan Van Der Made, Erksi̇n Güleç, Ahmet Cem Erkman Jan 2013

Microstonyx (Suidae, Artiodactyla) From The Upper Miocene Of Hayranlı-Haliminhanı, Turkey, Jan Van Der Made, Erksi̇n Güleç, Ahmet Cem Erkman

Turkish Journal of Zoology

The suid remains from localities 58-HAY-2 and 58-HAY-19 in the Late Miocene Derindere Member of the İncesu Formation in the Hayranlı-Haliminhanı area (Sivas, Turkey) are described and referred to as Microstonyx major (Gervais, 1848-1852). Microstonyx shows changes in incisor morphology, which are interpreted as a further adaptation to rooting. This occurred probably in a short period between 8.7 and 8.121 Ma ago and possibly is a reaction to environmental change. The incisor morphology in locality 58-HAY-2 suggests that it is temporally close to this change, which would imply that this locality and the lithostratigraphically lower 58-HAY-19 belong to the lower …
