Turkish Journal of Zoology
We report here that earthworm can be used as an in vivo system to prescreen antimitotic compounds. The known antimitotic compound colchicine and the aqueous extract of Acorus calamus L. rhizome were used to examine this system. The antimitotic activity of colchicine and the rhizome extract was confirmed by methods with Allium cepa root tip, earthworm regeneration, and MTT (3-(4,5-dimethyl thiazolyl-2-yl)-2,5-diphenyltetrazolium bromide). An earthworm regeneration assay examined the regeneration ability of tissues from amputated regions of the earthworm. All 3 assays showed that cell division is inhibited with colchicine and the aqueous extract of A. calamus rhizome. Histology studies with …

A Study On European Anchovy (Engraulis Encrasicolus) Swimbladder With Some Considerations On Conventionally Used Target Strength, Meltem Ok, Ali̇ Cemal Gücü
Turkish Journal of Zoology
Hydroacoustic surveys are one of the prime methods to assess the commercially top-ranked small pelagic stocks. The method relies on acoustic scattering from a fish, which is largely controlled by the size and morphology of the swimbladder. In this study, the changes in the size of the European anchovy swimbladder sampled in the Black Sea were investigated. Ventral cross-sectional area (by photographing the ventrally dissected fish) and volume (by dorsal and lateral X-raying) of the swimbladders were estimated. Comparison of areas showed that the stomach fill and presence of viscera did not have a statistically significant impact on the swimbladder …

Hibernation Perturbs The Number Of Hemocytes And Causes Hematological Turnover: Basal Traits To Understand Season-Dependent Physiological Variations In Helix Pomatia (Gastropoda: Helicidae), Damir Suljevic, Erna Islamagic, Alen Hamzic, Nadja Zubcevic, Andi Alijagic
Turkish Journal of Zoology
The total number of hemocytes and their morphological characteristics were analyzed in Helix pomatia Linnaeus, 1758, by light microscopy during different phases of hibernation. Three types of hemocytes were identified: hyalinocytes, agranulocytes, and granulocytes. Total number of hemocytes decreased significantly during hibernation. Most intensive changes in cell size, morphology, and appearance of special structures in granulocytes happened during the hibernation period itself. Termination of hibernation coincides with very important granulocyte transformation and the appearance of specific gigantic short-lived cells. All of the changes in cell number and morphology are characteristics of different hibernation phases and have a major role in …

Dew-Bathing In The Atlantic Forest Endemic Robust Woodpecker Campephilus Robustus (Lichtenstein, 1823) (Aves: Picidae), Paul Smith, Kevin P. Johnson
Turkish Journal of Zoology
The bathing behavior of woodpeckers (Picidae) is almost unknown and the paucity of reports of bathing in the family has led to suppositions that they may do so rarely. An unusual observation of the Atlantic Forest endemic Robust Woodpecker Campephilus robustus dew-bathing socially is reported from Paraguay and discussion of its significance follows. Dew-bathing has been reported for a small number of New World bird families and has often been linked to a shortage of water, but has never been previously reported in New World Picidae. Given the environmental conditions in this humid habitat it is considered that dew-bathing in …
