The Status Of Birds In The Proposed Rum Wildlife Reserve, Southern Jordan, Michael Evans, Zuhair Sami Amr, Ratib M. Al-Oran

Turkish Journal of Zoology

The Royal Society for the Conservation of Nature officially proposed the creation of the Rum Wildlife Reserve, in the extreme south of Jordan, in 1979. We present the first review of the birds of the proposed reserve and its environs, drawing upon published and unpublished records as well as a short field survey from June, 1996. A total of 142 species have been recorded, of which at least 34 species actually breed and another 14 probably do so. Most breeding species are (a) Saharo-Arabian desertic species, or (b) non-desertic species which have colonised the area due to the advent of …

Effects Of Agro Pesticides Cypermethrin And Malathion On Cholinesterase Activity In Liver And Kidney Of Calotes Versicolor Daudin (Agamidae: Reptilia), Muhammad Zaheer Khan

Turkish Journal of Zoology

Reptiles are long-lived, sedentary animals and therefore may be good biomonitors of their local habitat. Experiments were carried out to determine the effects of 2 agro-pesticides, cypermethrin and malathion, on the cholinesterase activity of Calotes versicolor Daudin. Two different concentrations, 0.1% and 1%, were used and cholinesterase activity was estimated in the liver and kidney. This decreased by up to 20% and 35% in the liver and 27% and 54% in the kidney under the effect of cypermethrin. In the case of malathion it decreased by up to 30.27% and 66.97% in the liver and 58.46% and 65.09% in the …

Food Of The Banded Newt, Triturus Vittatus Ophryticus (Berthold, 1846), At Different Sites In Trabzon, Bi̇lal Kutrup, Emel Çakir, Nurhayat Yilmaz

Turkish Journal of Zoology

The diet of the banded newt, Triturus vittatus ophryticus, from 3 different sites in northern Turkey was studied based on stomach contents from 180 samples (104 males + 76 females). The banded newt was found to forage on wide variety of prey organisms in the aquatic phase. Benthic invertebrates consistently made the greatest contribution to the diet, both numerically and volumetrically. Nektonic prey also appeared to be of importance in terms of volume but constituted few items. Terrestrial invertebrates contributed very little to the diet. In addition to invertebrates, a few amphibian prey items were found in the stomachs. The …

Observations On Some Behaviours Of Krüper’S Nuthatch (Sitta Krueperi), A Little-Known West Palaearctic Bird, Tamer Albayrak, Ali̇ Erdoğan

Turkish Journal of Zoology

Some intraspecific and interspecific behaviours in Krüper's Nuthatch (Sitta krueperi) populations were observed in Antalya province, southern Turkey. An account of their endemic distribution in Anatolia on the one hand, and the lack of sufficient data on the other, gave rise to the need for such a study. The breeding behaviour in the populations is observed, particularly in the BÜK (Lütfi Büyük Yıldırım research forest) and ELMALI Cedar research forests. The results are given in 2 parts as observed behaviours throughout a year and breeding period, which are mating, nesting, brooding, parental care and rearing and territorial behaviours.

Abnormalities In The Ozark Hellbender, (Cryptobranchus Alleganiensis Bishopi) In Arkansas: A Comparison Between Two Rivers With A Historical Perspective, Waylon R. Hiler, Benjamin A. Wheeler, Stanley E. Trauth

Journal of the Arkansas Academy of Science

We documented abnormalities of Ozark hellbender (Cryptobranchus alleganiensis bishopi) populations in the Eleven Point River (Randolph County, Arkansas) and the Spring River (Fulton County, Arkansas) as part of ongoing monitoring efforts in this species. We found abnormalities in 90% (9 of 10) and 40% (36 of 97) of hellbenders in the Spring River and Eleven Point River, respectively, during the 2003-2004 field seasons. Most abnormalities found in Eleven Point hellbenders were generally less invasive and seemed to be more intrinsic to the species' natural history (i.e., vicissitudes of living), whereas those found in Spring River hellbenders were gross morphological aberrations. …

A Study Of The Effects Of Probait On Chuditch, Dasyurus Geoffroii, Within The Julimar Conservation Park With Notes On The General Ecology, Melissa York

Theses : Honours

Broad scale fox baiting programs have been underway in Western Australia since 1996 when the Western Shield fauna recovery program commenced with the aim of recovering many fauna species that are under threat of extinction. Until recently, effective fox control for fauna recovery has been achieved with dried meat baits impregnated with the poison 1080. The Department of Conservation and Land Management (CALM) has developed more readily available and cost effective sausage meat baits, termed Probait. As bait acceptability trials in the laboratory indicated a potential risk from Pro bait ingestion by chuditch (Dasyurus geoffroii), assessment of the likely risk …

Recent Records Of Formerly Extirpated Carnivores In Nebraska, Justin D. Hoffman, Hugh H. Genoways Jan 2005

Recent Records Of Formerly Extirpated Carnivores In Nebraska, Justin D. Hoffman, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

By the early 1900's, several large carnivores had been extirpated from Nebraska as a result of unrestricted hunting and trapping by early European settlers. Recently, there have been several confirmed records of carnivores that were once extirpated from Nebraska. In our study, we present new data for five species that recently were documented in Nebraska: Lynx canadensis, Ursus americanus, Canis lupus, Puma concolor, and Lontra canadensis. Restoration programs and legal protection afforded to these species in Nebraska and in adjacent states have allowed population numbers to increase. Because of the increase in populations of these …

Mechanical Properties Of The Integument Of The Common Gartersnake, Thamnophis Sirtalis (Serpentes: Colubridae), Gabriel Rivera, Alan H. Savitzky, Jeffrey A. Hinkley

Biological Sciences Faculty Publications

The evolution of the ophidian feeding mechanism has involved substantial morphological restructuring associated with the ability to ingest relatively large prey. Previous studies examining the morphological consequences of macrophagy have concentrated on modifications of the skull and cephalic musculature. Although it is evident that macrophagy requires highly compliant skin, the mechanical properties of the ophidian integument have received limited attention, particularly in the context of feeding. We examined mechanical properties of skin along the body axis in Thamnophis sirtalis (Colubridae). Data were collected from tensile tests and were analyzed using a multivariate analysis of variance (MANOVA) and post-hoc multiple comparison …
