The Effect Of Disturbances To Habitat Quality On Otter (Lutra Lutra) Activity In The River Kızılırmak (Turkey): A Case Study, İlhami̇ Tüzün, İrfan Albayrak
The Effect Of Disturbances To Habitat Quality On Otter (Lutra Lutra) Activity In The River Kızılırmak (Turkey): A Case Study, İlhami̇ Tüzün, İrfan Albayrak
Turkish Journal of Zoology
Habitat restriction for otters living in a small part of the Kızılırmak River occurred due mainly to 3 causes: dam construction at the upper end, heavy pollution by oil refinery effluent at the lower end and man-made activities such as housing and angling in-between. Sprainting activity was measured to assess habitat use by otters within the area and differences were shown between the sites. Compared to site II, higher sprainting activity was found at the site below the dam (site I), where habitat quality was poorer, as indicated by the water quality index (BMWP), diversity indices (Simpson's and Shannon-Wiever) and …

Population Status Of The Taurus Frog, Rana Holtzi Werner (1898), In Its Terra Typica: Is There A Decline?, Uğur Kaya, İ. Ethem Çevi̇k, Uğur C. Eri̇şmi̇ş
Turkish Journal of Zoology
The herpetofauna of the Taurus Mountains is diverse, and many species are locally abundant. The Taurus frog, Rana holtzi, is endemic to Maden Lake in the Taurus Mountains in Turkey. Although it was thought to be abundant in its restricted habitat, the population size of the Taurus frog and its related trend are uncertain. Like many animals, a great number of anurans have declined or become extinct over the past decades. In 2003, we conducted a mark-recapture study on the Taurus frog population in its terra typica. Our objective was to monitor R. holtzi in its terra typica to estimate …

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.

Sexual Dimorphism In Podarcis Sicula Campestris, Milan Vogrin
Turkish Journal of Zoology
Morphometric characters (snout-vent length, tail length, head length, head width, and number of ventrals and gulars) were analysed in 58 male and 44 female Italian Wall Lizards, Podarcis sicula campestris, from the Adriatic coast of Slovenia. The Italian Wall Lizard is significantly dimorphic in most characters analysed. Males were significantly larger than females. No differences between sexes were found in the number of gulars, whereas the number of transversal rows of ventrals was significantly higher in females (27-30) than in males (24-27).

Small Fish Species Of Arkansas Reservoirs, Thomas M. Buchanan
Small Fish Species Of Arkansas Reservoirs, Thomas M. Buchanan
Journal of the Arkansas Academy of Science
Sixty-six Arkansas reservoirs were sampled with rotenone from 1997 through 2004 to determine the distribution and species richness of small, nongame fish species in manmade lentic environments. Eighty-five small fish species distributed among 13 families were collected. Fish distribution and species richness varied by reservoir size, ecoregion, and reservoir type. Species richness was significantly correlated with reservoir size and the number of small species occurring in reservoir drainages. Some small species apparently maintained breeding populations in reservoirs, other species occurred in low numbers and may not have maintained breeding populations, and some species occurred sporadically, probably as stragglers from nearby …

Seasonal Incidence Of Sperm Within The Spermathecae Of Ouachita Dusky Salamanders (Desmognathus Brimleyorum) In Arkansas, Stanley E. Trauth, Michelle N. Mary
Journal of the Arkansas Academy of Science
We examined 91 adult female Ouachita dusky salamanders {Desmognathus brimleyorum) to determine the seasonal incidence of sperm within spermathecae. The spermatheca (sperm storage gland) along with supporting tissue was removed from the dorsal cloacal wall of each female and prepared for light microscopy. We recorded the reproductive condition of females (diameter of enlarged ovarian follicles =EOF) and found large aggregates of sperm within the spermathecae during all months, except February (no specimens available). The highest incidence of sperm in spermathecae occurred in July specimens (53%; n = 17). Although the known nesting season runs from July into August in this …

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. …
