Ecology And Biology Of Scorpions In Palmyra, Syria, Adwan Hussien Shehab, Zuhair Sami Amr, Jeremy Arthur Lindsell

Turkish Journal of Zoology

Near Palmyra, in the Syrian Desert, 5 species of scorpions belonging to 2 families (Buthidae and Scorpionidae) were observed; Buthacus tadmorensis, Androctonus crassicauda, Leiurus quinquestriatus, Orthochirus scrobiculosus, and Scorpio maurus palmatus. B. tadmorensis accounted for 80.6% of the total number of recovered or observed scorpions, while O. scrobiculosus was the least common (1.4%). Pitfall traps proved to be more efficient at sampling (304 individuals) than checking under stones (57 individuals). Pitfall trapping results showed that scorpion abundance differed significantly between the 3 survey areas, while their abundance showed no significant difference among the 3 areas when employing the under-stone method. …

Taxonomic Status Of Myotis Myotis (Borkhausen, 1797) And Myotis Blythii (Tomes, 1857) In Turkey(Mammalia: Chiroptera)*, Nursel Aşan, İrfan Albayrak

Turkish Journal of Zoology

Morphometrical, biological, ecological, and karyological data of 156 Myotis myotis and 149 M. blythii specimens collected from various provinces of Turkey between 1974 and 2007 were evaluated. Specimens from Turkish Thrace were referred to as M. m. myotis and the Mediterranean part as M. m. macrocephalicus. Specimens from the rest of Anatolia were assigned to an intermediate form. Due to a steady increase in body and cranial size detected in Myotis blythii from western to eastern Anatolia, we did not assign a subspecific name for the M. blythii populations in Turkey. In addition, body and cranial measurements of this species …

A Brief Review Of Morphological Variation In Natrix Tessellata In Israel: Between Sides, Among Individuals, Between Sexes, And Among Regions, Yehudah Leopold Werner, Tal Shapira

Turkish Journal of Zoology

After introducing the distribution and biology of Natrix tessellata in Israel, on the southern edge of its range, we address its intraspecific variation from the literature and examination of 262 museum specimens. Head pholidosis showed no significant directional asymmetry, but asymmetry in infralabial plates was significantly correlated with frequency of injured tails. Variation in body size showed no clear seasonal growth, presumably due to climatic fluctuations. The variation in number of ventrals (in males, 159-173, mode 165) was not geographical. Females attained 750-800 mm (head and body; mode 600-650) and males 700-750 (mode 500-600) mm. Females had significantly greater relative …

Phylogeography Of Northern Populations Of The Black-Tailed Rattlesnake (Crotalus Molossus Baird And Girard, 1853) With The Revalidation Of C. Ornatus Hallowell, 1854, Christopher Anderson Jan 2011

Phylogeography Of Northern Populations Of The Black-Tailed Rattlesnake (Crotalus Molossus Baird And Girard, 1853) With The Revalidation Of C. Ornatus Hallowell, 1854, Christopher Anderson

Open Access Theses & Dissertations

The black-tailed rattlesnake (Crotalus molossus Baird and Girard, 1853) is a wide-ranging species complex with representatives from the southwestern United States through the highlands of central and southern Mexico. The systematics of this group has received little attention and in the past six decades only two taxonomic revisions have been proposed (the transfer of C. basiliscus oaxacus to C. molossus and the elevation of C. m. estebanensis to full species). However, a recent revision of the Neotropical rattlesnakes (C. durissus and C. simus) recovered a polyphyletic C. molossus. Sequenced data were obtained from three mitochondrial genes …


A Comparison Of Prairie Vole Audible And Ultrasonic Pup Calls And Attraction To Them By Adults Of Each Sex, Thomas A. Terleph Jan 2011

A Comparison Of Prairie Vole Audible And Ultrasonic Pup Calls And Attraction To Them By Adults Of Each Sex, Thomas A. Terleph

Biology Faculty Publications

Rodent pups of many species emit both ultrasonic vocalizations (USVs) and calls spanning into a lower frequency range, audible to humans (AUDs), yet there has been little systematic comparison of these different call types, or analyses of how they might differ in signal function. Here the spectral and temporal characteristics of USV and AUD pup calls are described for the prairie vole (Microtus ochrogaster), a model used in studies of monogamous mating and biparental care, and a species with an unusually large functional and anatomical representation of auditory cortex. Findings provide a detailed description of each call type, …

Responses To The Assurance Game In Monkeys, Apes, And Humans Using Equivalent Procedures, Sarah F. Brosnan, Audrey E. Parrish, Michael J. Beran, Timothy Flemming, Lisa Heimbauer, Catherine F. Talbot, Susan P. Lambeth, Steven J. Schapiro, Bart J. Wilson

ESI Publications

There is great interest in the evolution of economic behavior. In typical studies, species are asked to play one of a series of economic games, derived from game theory, and their responses are compared. The advantage of this approach is the relative level of consistency and control that emerges from the games themselves; however, in the typical experiment, procedures and conditions differ widely, particularly between humans and other species. Thus, in the current study, we investigated how three primate species, capuchin monkeys, chimpanzees, and humans, played the Assurance (or Stag Hunt) game using procedures that were, to the best of …

Flank Gland-Secreted Putative Chemosignals Pertaining To Photoperiod, Endocrine States, And Sociosexual Behavior In Golden Hamsters, Ying-Juan Liu, Da-Wei Wang, Lixing Sun, Jin-Hua Zhang, Jian-Xu Zhang

All Faculty Scholarship for the College of the Sciences

Behavioral studies have shown that flank glands are involved in chemical communication in golden hamsters Mesocricetus auratus but little chemical analysis has been conducted on volatiles arising from these glands. Using gas chromatography- mass spectrometry, we detected compounds from the flank glands of males, only eight of which were also produced in females. Based on these chemical data we performed a number of further experiments. By manipulating light we found that males exposed to short-photoperiods developed smaller flank glands than those exposed to long-photoperiods. Six flank gland volatiles reduced in relative abundance, which possibly coded for reproductive status of males …


Fall Field Report, August–November 2010, W. Ross Silcock Dec 2010

Fall Field Report, August–November 2010, W. Ross Silcock

Nebraska Bird Review

This was a pretty routine fall for the most part, although there were scattered early and late dates and high counts as in most seasons. Decidedly non-routine, though, was the appearance of two rarities, Ross's Gull and Brown-headed Nuthatch, both enjoyed by many. A surprising 15 gull species were reported, this without much help from L McConaughy! Also notable were the sea-ducks, scoters, and Long-tailed Duck, which were in good numbers.

Tom Labedz, collections manager at the University of Nebraska State Museum, is an excellent source; he contributed greatly to discussions herein on Greater Prairie-Chicken and Fox Sparrow.
