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 …

Endangered Basra Reed-Warbler (Acrocephalus Griseldis) Recorded For The First Time In Turkey (Aves: Acrocephalidae), Montague H. C. Neate-Clegg, Juan Ramírez Román, Berkan Demi̇r, Çağan Hakki Şekerci̇oğlu

Turkish Journal of Zoology

The Basra Reed-warbler (Acrocephalus griseldis) is an endangered songbird that breeds in the reed beds of southern Mesopotamia. Hydrological projects, war, and drought have greatly reduced the breeding habitat of this species, making its future uncertain. The first Basra Reed-warbler for Turkey was caught in a mist net on 22 May 2018 at the Aras River Ornithological Research Station, between the provinces of Kars and Iğdır. This represents one of only a few vagrant records in the eastern Mediterranean, and the northernmost record to date. It is likely that this bird was an overshooting spring migrant, but the existence of …

Dew-Bathing In The Atlantic Forest Endemic Robust Woodpecker Campephilus Robustus (Lichtenstein, 1823) (Aves: Picidae), Paul Smith, Kevin P. Johnson Jan 2019

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 …

Application Of Multifactorial Discriminant Analysis In The Morphostructural Differentiation Of Wild And Cultured Populations Of Vieja Azul (Andinoacara Rivulatus), Johanna Caez, Ana Gonzalez, Martin A. Gonzalez, Elena Angon, Jorge M. Rodriguez, Francisco Peña, Cecilio Barba, Antón García

Turkish Journal of Zoology

To better determine the ecological variation (body shape and structure) of the Vieja Azul (Andinoacara rivulatus; syn.: Aequidens rivulatus) in northwest Ecuador (Los Ríos Province), 300 specimens of both sexes (150 male and 150 female) were collected from 3 different locations, one from a wild production system and two from fish farm populations in the Quevedo River. Twelve meristic, 26 traditional morphometric, and 32 truss measurements, among 25 anatomical landmarks, were determined. The body weight (BW), total length (TL), eye diameter (ED), dorsal fin ray length (DFRL), and body perimeter 3 (P3) showed significant differences (P < 0.05) between production systems, and sex had significant influence on preanal length (Pre-AL), P3, and body width 2 (LC2). Females showed higher mean values than males in all measurements, except for BW. The Fulton factor differed for both factors considered. The canonical discriminant analysis revealed a percentage of correct assignment of 64.42% for the dataset, 85% and 60.9% for cultured and wild females, and 62.1% and 56.3% for wild and cultured males, respectively, as well as morphometric variation between groups. Results could be attributed to environmental conditions (habitat, temperature, and food). The Mahalanobis test showed greater distances among females than among males. In conclusion, this study provides valuable morphological information on the shape and structure of Andinoacara rivulatus that can be used to characterize and quantify the changes that occur as a consequence of adaptation to a different habitat. The authors hope that the information obtained from the present study will be helpful for fisheries, biologists, and taxonomists.

Molecular Identification Of Invasive Drosophilid Zaprionus Tuberculatus Malloch (Diptera: Drosophilidae) In Çanakkale, Turkey, Akin Kuyulu, Seda Yücel, Hani̇fe Genç

Turkish Journal of Zoology

The vinegar or pomace fly, Zaprionus tuberculatus Malloch, is native to the Afrotropical region but has recently colonized new areas in Turkey, Italy, Malta, Romania, and Greece. This invasive species was first detected in 2012 in Adana on banana and peach baits and is considered a potential agricultural pest in fig production in Turkey. However, the European and Mediterranean Plant Organization reports that no direct association of the fly with fruit damage has been documented so far because specimens were generally caught in traps. Specimens of Zaprionus sp. were monitored during surveys for cases of Drosophila suzukii (Matsumura) and Ceratitis …

Induction Of Abnormal Sperm Heads In Small Mammals Under Chronic Ionizing Radiation, Lyudmila Bashlykova, Oksana Raskosha, Natalia Starobor Jan 2019

Induction Of Abnormal Sperm Heads In Small Mammals Under Chronic Ionizing Radiation, Lyudmila Bashlykova, Oksana Raskosha, Natalia Starobor

Turkish Journal of Zoology

The results of this study show a mutagenic effect of low-dose ionizing radiation in male germ cells. The damage of male germ cells was assessed by the frequency of abnormal sperm heads in tundra voles (Microtus oeconomus Pall.), bank voles (Myodes glareolus Schreb.), and field mice (Apodemus agrarius Pall.) from the 30 km exclusion zone around the Chernobyl nuclear power station and for laboratory animals (mice and rats) under chronic γ-irradiation. The abnormal sperm head detection method used appeared to be sensitive to conditions of low-dose irradiation and can consequently be recommended as a bioindicator to monitor environmental radiation pollution.
