Clutch And Egg Size Variation, And Productivity Of The House Sparrow (Passer Domesticus): Effects Of Temperature, Rainfall, And Humidity, AZİZ ASLAN, MUSTAFA YAVUZ 2010 TÜBİTAK

Clutch And Egg Size Variation, And Productivity Of The House Sparrow (Passer Domesticus): Effects Of Temperature, Rainfall, And Humidity, Azi̇z Aslan, Mustafa Yavuz

Turkish Journal of Zoology

This study was conducted on the campus of the regional department of the forestry service, encompassing 2.25 ha in Antalya city center. The area has gardens and is surrounded by trees, providing nesting and feeding opportunities for many songbird species. The study aimed to determine clutch and egg size variation, breeding success, and productivity of the House Sparrow (Passer domesticus), in terms of clutch size and breeding attempts, and to evaluate variation in temperature, rainfall, and humidity in terms of breeding attempts and years, and their possible effects on given parameters of the species. In total, 2016 eggs were laid …


Changes In Spring Migration Of The Wood Pigeon (Columba Palumbus) In Northwestern Croatia, ZDRAVKO DOLENEC, PETRA DOLENEC 2010 TÜBİTAK

Changes In Spring Migration Of The Wood Pigeon (Columba Palumbus) In Northwestern Croatia, Zdravko Dolenec, Petra Dolenec

Turkish Journal of Zoology

Several papers have shown the sensitivity of birds as monitors of climatic trends. We examined how a short-distance migrant bird, the wood pigeon, has responded to the recent climate change using data from a long-term study (1983-2007) in northwestern Croatia. The wood pigeon arrival dates have become 11.5 days earlier during the study period. This result suggests that the first arrival date of the wood pigeon is influenced by warm springs.


Occurrence Of Trypanosoma Sp. In Wild African Sharptooth Catfish (Clarias Gariepinus Burchell, 1822) In The River Asi (North-Eastern Mediterranean), Turkey, EGEMEN KONAŞ, ERCÜMENT GENÇ, GALİP KAYA, CAVİT EROL 2010 TÜBİTAK

Occurrence Of Trypanosoma Sp. In Wild African Sharptooth Catfish (Clarias Gariepinus Burchell, 1822) In The River Asi (North-Eastern Mediterranean), Turkey, Egemen Konaş, Ercüment Genç, Gali̇p Kaya, Cavi̇t Erol

Turkish Journal of Zoology

Fifteen African sharptooth catfish (Clarias gariepinus Burchell, 1822) were collected from the River Asi (River Orontes) in Antakya (Hatay, Turkey) in November 2007, and fish blood samples were examined for the presence of blood parasites. The existence of infection with Trypanosoma (hemoparasite) was identified in 13 out of the 15 fish specimens. Currently there are no records of the presence of any species of Trypanosoma infecting Clarias gariepinus in Anatolia. Thus this study is the first report of Trypanosoma sp. infections in Clarias gariepinus in Turkey.

New Records For Turkish Tachinidae (Diptera) Fauna, Kenan Kara, Yasemi̇n Kormaz, Serhat Kirikoğlu

Turkish Journal of Zoology

Nine Tachinidae species were recorded for the first time in Turkey. These are Medina melania (Meigen), Acemya acuticornis (Meigen), Allophorocera ferruginea (Meigen), Graphogaster vestita Rondani, Phasia pandellei (Dupuis), Xysta holosericea (Fabricius), Leucostoma tetraptera (Meigen), Cylindromyia interrupta (Meigen), and Besseria lateritia (Meigen).


Female Humpback Whale (Megaptera Novaeangliae) Reproductive Class And Male-Female Interactions During The Breeding Season, Meagan E. Jones 2010 Antioch University of New England

Female Humpback Whale (Megaptera Novaeangliae) Reproductive Class And Male-Female Interactions During The Breeding Season, Meagan E. Jones

Antioch University Dissertations & Theses

This study examined whether female reproductive class (i.e., presence or absence of a calf) in humpback whales (Megaptera novaeangliae) affects female behavior and male-female interactions on the Hawaiian breeding grounds. From 2003-2008, 295 female-calf groups (with or without a male escort) and 256 female no-calf groups (with a male) were observed. Forty-one female no-calf groups were confirmed male-female pairs by genetic sexing or photo-identification. Focal follows of 36 male-female pairs and 50 female-calf groups (29 escorted and 21 unescorted female-calf groups) were analyzed for time budget and movement estimates. Relative fluke size (fluke photogrammetry, n=30) and sighting histories …


Morphological Differences Among Eyeless Amphipods In The Genus Stygobromus Dwelling In Different Subterranean Habitats, David C. Culver, John R. Holsinger, Mary C. Christman, Tanja Pipan 2010 Old Dominion University

Morphological Differences Among Eyeless Amphipods In The Genus Stygobromus Dwelling In Different Subterranean Habitats, David C. Culver, John R. Holsinger, Mary C. Christman, Tanja Pipan

Biological Sciences Faculty Publications

The amphipod genus Stygobromus occurs in a variety of subterranean habitats in North America, including caves, phreatic (groundwater) lakes, and superficial subterranean habitats (seeps and epikarst). The habitats share the absence of light but differ in other features, such as pore size of the habitat, available food, and degree of seasonality. Measurements of body size, antennal size, and antennal segment number of type specimens were compared for 56 species occurring in the eastern United States. Except for differences in body size, differences among species in the four different habitats were not significant. Body size was related to relative pore size …


The Impact Of Conservation On The Status Of The World's Vertebrates, Michael Hoffmann, Craig Hilton-Taylor, Ariadne Angulo, Monika Böhm, Thomas M. Brooks, Stuart H. M. Butchart, Kent E. Carpenter, Janice Chanson, Beth A. Polidoro, Jonnell C. Sanciangco 2010 Old Dominion University

Biological Sciences Faculty Publications

Using data for 25,780 species categorized on the International Union for Conservation of Nature Red List, we present an assessment of the status of the world's vertebrates. One-fifth of species are classified as Threatened, and we show that this figure is increasing: On average, 52 species of mammals, birds, and amphibians move one category closer to extinction each year. However, this overall pattern conceals the impact of conservation successes, and we show that the rate of deterioration would have been at least one-fifth again as much in the absence of these. Nonetheless, current conservation efforts remain insufficient to offset the …
