The Morphology, Taxonomy, And Distribution Of Specimens Of Darevskia Clarkorum (Sauria: Lacertidae: Darevskia) Collected From Turkey’S Eastern Black Sea Region, Çeti̇n Ilgaz Jan 2007

The Morphology, Taxonomy, And Distribution Of Specimens Of Darevskia Clarkorum (Sauria: Lacertidae: Darevskia) Collected From Turkey’S Eastern Black Sea Region, Çeti̇n Ilgaz

Turkish Journal of Zoology

In all, 103 specimens of Clark's lizard, Darevskia clarkorum (Darevsky and Vedmederja, 1977), from 6 localities in the eastern Black Sea region of Turkey were examined in terms of pholidosis characteristics, morphometric measurements, and color and pattern features. Kolmogorov-Smirnov testing across all populations verified sexual dimorphism in the Ortacalar and Hemşin populations, regarding transversal series of ventral plates (P < 0.05). According to the Mann-Whitney U test, 16 pholidosis characteristics showed differences among the populations (P < 0.05). For comparison of morphometric measurements, 4 morphometric indices and ratios were developed. According to the results of independent t-testing, no differences were found between males and females among the populations. One-way variance analyses based on 4 morphometric indices and ratios confirmed that head index, snout-vent length/tail length, and tail length/total body length showed differences among the populations (P < 0.05). Regarding pholidosis characteristics (except rates of the presence of a masseteric plate and contact between the rostral and internasal plate), morphometric measurements, and color and pattern features, the specimens collected from 6 different localities were similar to D. clarkorum specimens mentioned in the literature. Furthermore, the known range of the species in Turkey has been extended.

Life Cycle Of Gammarus Pulex (L.) In The River Yeşilırmak, Mustafa Duran Jan 2007

Life Cycle Of Gammarus Pulex (L.) In The River Yeşilırmak, Mustafa Duran

Turkish Journal of Zoology

Monthly sampling of Gammarus pulex for 45 months in the River Yeşilırmak showed that the mean seasonal population density increased to a maximum in summer, and then declined to the lowest level in winter. There was a consistent seasonal pattern of body length distributions, characterised by the arrival of a strong cohort of new juveniles in spring and early summer. The ovigerous adults were few in autumn, peaked around January to March, and were virtually absent from July to October. Estimated sex ratios obtained from the field in general seem to show that females predominated, except in summer.

Non-Invasive Technique For Assessing The Population Parameters Of Metacercariae Of Clinostomum Marginatum In Smallmouth Bass(Micropterus Dolomieu), James J. Daly Sr., Randal J. Keller, Bruce Deyoung Jan 2007

Non-Invasive Technique For Assessing The Population Parameters Of Metacercariae Of Clinostomum Marginatum In Smallmouth Bass(Micropterus Dolomieu), James J. Daly Sr., Randal J. Keller, Bruce Deyoung

Journal of the Arkansas Academy of Science

Clinostomllm marginatum is a trematode that uses a fish as its final intennediate host. The wonns in the fish are in metacercarial cysts and are known as yellow grub. Yellow grubs give the fish's flesh a wonny, unappetizing appearance and are a problem for commercial fish fanners in that heavily infected fish are not suitable for marketing. The parasite is common in smallmouth bass (Micropterus dolomieu) living in upland streams of Arkansas where the bass may serve as a wild reservoir for contamination of commercial fish ponds. Because smallmouth bass are a prized game fish, it would be desirable to …
