A Comparison Of The Structure Of 2 Waterbird Assemblages During Postbreeding Movements In The Arid Zone Of Uzbekistan, Zbigniew Kasprzykowski, Artur Golawski, Cezary Mitrus, Tomasz Stanski
Turkish Journal of Zoology
Natural riverbeds in arid regions of Central Asia play an important role in waterbird migration. However, agricultural irrigation in the Aral Sea basin, in combination with climate change, is leading to wetland habitat loss. In this study, we consider the importance of the 2 largest river systems in this region during postbreeding movements and compare waterbird assemblages in relation to habitat parameters between the Amu-Darya and Syr-Darya rivers. In the second half of August 2011, we counted waterbirds along 125 and 106 km of the Amu-Darya and Syr-Darya rivers, respectively. Both rivers showed a high similarity of richness indices. Analysis …
Embryonic Development Of The Olive Fruit Fly, Bactrocera Oleae Rossi (Diptera: Tephritidae), In Vivo, Hani̇fe Genç
Embryonic Development Of The Olive Fruit Fly, Bactrocera Oleae Rossi (Diptera: Tephritidae), In Vivo, Hani̇fe Genç
Turkish Journal of Zoology
The olive fruit fly, Bactrocera oleae (Rossi) (Diptera: Tephritidae), is a pest that infests olive fruits. The female oviposits in large green olives and larvae hatch inside the fruit, where they feed upon the fruit tissues. Larval development is completed inside the fruit. These flies cause great damage to olive production worldwide. Traditionally, insecticides have been directed against the adult stage, but the results are not efficient. This present work is a study of embryogenesis in the olive fruit fly. The external morphology of the Bactrocera oleae Rossi (Diptera: Tephritidae) egg is described from light microscopy without dechorionation. The observations …

Effect Of Reed Burning And Precipitation On The Breeding Success Of Great Reed Warbler, Acrocephalus Arundinaceus, On A Mining Pond, Thomas Oliver Méro, Antun Zuljevic, Katalin Varga, Renata Bocz, Szabolcs Lengyel
Turkish Journal of Zoology
In this study, we present the effects of reed burning and precipitation on the breeding success of Great Reed Warblers on a mining pond (2008-2011). Breeding success, i.e. the probability that an egg would produce a fledgling, was 0.43. Clutch survival was lowest in 2010, due to the precipitation and high water level during the season. Breeding success was higher in the second half of the breeding season, although in 2008 and 2011 precipitation was also higher in the second half than in the first half of the breeding season. During the first half of the breeding season, daily egg …

Seasonal Variations In Immunoreactive Cortisol And Fecal Immunoglobulin Levels In Sichuan Golden Monkey (Rhinopithecus Roxellana), Shuai Huang, Lian Li, Jie Wu, Chengmin Li, Jingyan Bai, Yu Sun, Genlin Wang
Turkish Journal of Zoology
The Sichuan golden monkey is deserving of conservation and the welfare of this species is receiving increasing attention. However, it is difficult to identify physiological parameters for assessing its conservation status. In the present study, we employed noninvasive sampling methods and immunochemical assays to determine if measurements of cortisol and immunoglobulin in feces allowed monitoring of physiological status. The results indicated that the cortisol and immunoglobulin concentrations in feces could serve as biomarkers for monitoring stress and immune status, and that there was a relationship between stress and the immune response. A tendency toward seasonal fluctuation in immunoreactive cortisol and …

Is The Subfamily Eriosomatinae (Hemiptera: Aphididae) Monophyletic?, Xingyi Li, Liyun Jiang, Gexia Qiao
Is The Subfamily Eriosomatinae (Hemiptera: Aphididae) Monophyletic?, Xingyi Li, Liyun Jiang, Gexia Qiao
Turkish Journal of Zoology
Eriosomatinae, the gall-forming aphid subfamily, traditionally consists of 3 tribes, Eriosomatini, Pemphigini, and Fordini. However, the phylogenetic relationships among these tribes remain controversial, which has made it difficult to conduct further investigation regarding the evolution of galls and host alternations in this group. We analyzed the molecular phylogeny of the subfamily Eriosomatinae, combining sequences from 2 mitochondrial genes (COI and COII) and 2 nuclear genes (EF-1\alpha and LWO). The reconstructions were implemented based on single-gene and multigene datasets through 3 different reconstructing algorithms, respectively; analyses with 5 different out-groups were also conducted. Results revealed a large paraphyletic clade, in which …

The Tubificids (Annelida, Oligochaeta) Of Lake Trasimeno And Lake Piediluco In Central Italy, With A Study Of Sem Morphology Of Some Species, Enzo Goretti, Caterina Marcucci, Alessandra Di Veroli, Angelisa Fabrizi, Elda Gaino
Turkish Journal of Zoology
Freshwater oligochaetes are studied worldwide because of their relevance as bioindicators in aquatic ecosystems. Nevertheless, species identification is still difficult because it is mainly based on the male reproductive system. The morphology of the chaetae offers an additional set of characters and the fine organization of these elements can help in solving crucial aspects allowing specific attribution. In spite of this, somatic chaetae are poorly investigated under scanning electron microscopy (SEM). A SEM analysis of the chaetae has been carried out on the tubificids Branchiura sowerbyi, Limnodrilus hoffmeisteri, Tubifex tubifex, and Psammoryctides barbatus from Trasimeno and Piediluco lakes (Central Italy). …
