Temperature Regulation And The Constraints Of Climate In The Eared Grebe, Hugh I. Ellis, Joseph R. Jehl Jr
Temperature Regulation And The Constraints Of Climate In The Eared Grebe, Hugh I. Ellis, Joseph R. Jehl Jr
Biology: Faculty Scholarship
Eared Grebes (Podiceps nigricollis) encounter a variety of climatic regimes in their annual cycle. The most dramatic occur while on staging areas in autumn. We investigated the thermoregulatory abilities of the Eared Grebe to determine how they coped with these climate changes during staging. The basal metabolic rate (BMR) was higher than predicted. Mass-specific BMR was 1.212 mL O2/g·h for birds averaging 317 g. The thermoneutral zone is wide and extended from 15°C to 38°C. Minimal thermal conductance and average body temperature were not unusual. We conclude that Eared Grebes live most of the year under thermoneutral conditions and that …

Observations On The Mole Vole, Ellobius Lutescens Thomas 1897, (Mammalia: Rodentia) In Turkey, Yüksel Coşkun, Servet Ulutürk
Turkish Journal of Zoology
Ellobius lutescens is the only species of the genus Ellobius living in eastern Anatolia. They are highly adapted to underground life. There is no knowledge about the ecological peculiarities, population structures or detailed range of this species in Turkey. Data were recorded during field studies and laboratory observations of 42 specimens collected from 12 different localities. The distribution area is 8 km north of Muradiye in the north, the eastern border beyond the Turkish border, 32 km north of Çatak in the south, 5-6 km east of Uysal in the west, and Yüksekova in the southeast, the eastern border beyond …

The Lepidoptera (Insecta) Fauna Of Düzce Province, Turkey, Süleyman Akbulut, Beşi̇r Yüksel, Aki̇f Keten
Turkish Journal of Zoology
The lepidopteran species of Düzce province were investigated. To collect specimens, a sweep net and light traps were used. A total of 109 species belonging to 17 families of the order Lepidoptera were identified. The family Geometridae was represented by the highest number of species (20), followed by Noctuidae (19), Lycaenidae (12) and Nymphalidae (12). This was the first study to determine the Lepidoptera fauna of Düzce.
A Study On The Morphology, Karyology And Distribution Of Ellobius Fisher, 1814 (Mammalia: Rodentia) In Iran, Muhammed Mouradi Gharakheloo, Erkut Kivanç
A Study On The Morphology, Karyology And Distribution Of Ellobius Fisher, 1814 (Mammalia: Rodentia) In Iran, Muhammed Mouradi Gharakheloo, Erkut Kivanç
Turkish Journal of Zoology
In this study, 180 mole-vole specimens collected from west, central, east and southeast Iran were investigated by morphological, biometrical and karyological methods. According to our findings, 3 different species, Ellobius fuscocapillus, Ellobius lutescens and Ellobius talpinus, are distributed in Iran. Karyological findings showed that E. fuscocapillus has 2n = 36 (NF = 58, NFa = 54), E. lutescens has 2n = 17 (NF = 34, NFa = 32) and E. talpinus has 2n = 52 (NF = 54, NFa = 50) chromosomes.
The Distribution Of Three Exotic Fishes In Anatolia, Hüseyi̇n Şaşi, Süleyman Balik
The Distribution Of Three Exotic Fishes In Anatolia, Hüseyi̇n Şaşi, Süleyman Balik
Turkish Journal of Zoology
Three exotic fish species, Lepomis gibbosus (L., 1758), Pseudorasbora parva (Temminck & Schlegel, 1846) and Carassius gibelio (Bloch, 1782), were recorded in Topçam Dam Lake from a new locality in Asia Minor. The pumpkinseed sunfish, stone moroko and wild goldfish were found as a result of studies performed on the reservoir in Aydın province, Turkey, between June 1999 and June 2000. This study is one of the first records on the distribution of these fishes in Topçam Dam Lake, Anatolia. These 3 species had been recorded from the Thrace region of Turkey, as well as Pseudorasbora parva in the Antalya …
Helminth Infections In Tench (Tinca Tinca) From Kapulukaya Dam Lake, Kader Yildiz
Helminth Infections In Tench (Tinca Tinca) From Kapulukaya Dam Lake, Kader Yildiz
Turkish Journal of Veterinary & Animal Sciences
This study was conducted to determine helminth infections in tench (Tinca tinca), caught in Kapulukaya dam lake. The tench were transferred to the laboratory alive or recently dead. Thereafter, they were necropsied. Postmortem examination of the fish revealed that 84% were positive for various helminth species. Asymphylodora tincae (97.6%), Pomphorhynchus laevis (26.1%), metacercariae (15.4%), plerocercoids of Ligula sp. (5.9%) and nematode larvae (2.2%) were detected in infected fish. A. tincae was found in the intestine, P. laevis was found both in the intestine and in the abdominal cavity, plerocercoids of Ligula sp. were found only in the abdominal cavity, while …

A Study On Micromys Minitus (Pallas, 1771) (Mammalia: Rodentia) In Turkish Thrace, Beytullah Özkan, Nuri̇ Yi̇ği̇t, Ercüment Çolak
Turkish Journal of Zoology
Micromys minutus was recorded from six localities in Turkish Thrace. The external, cranial and karyological peculiarities of the specimens were determined. The dorsal colour of the specimens is dark brownish, being lighter on the sides, but the rostrum and cheek are markedly ochre. Mean tail length relative to body length is 90.5%, and the occipito-nasal length is 18.1 mm. The diploid number of chromosomes was 2n = 68 with NF = 136 and NFa = 132.

The Taxonomy And Distribution Of Apodemus Agrarius (Pallas, 1771) (Mammalia: Rodentia) In The European Part Of Turkey, Haluk Kefeli̇oğlu, Coşkun Tez, İslam Gündüz
Turkish Journal of Zoology
The morphological and karyological characteristics of 27 specimens of Apodemus agrarius (Pallas, 1771) from the European part of Turkey were studied in detail and compared with those in the literature in order to provide a wider perspective on the taxonomic status of Apodemus agrarius in Turkey. In all the samples examined, 2n = 48 karyotype was observed with FN = 56 and FNa = 54. The 2n = 48 karyotype includes three pairs of metacentric, one pair of submetacentric and 19 pairs of acrocentric autosomes. Of the sex chromosomes, the X is a large acrocentric and the Y is a …
