On The Distribution And Morphology Of The Steppe Viper, Vipera Eriwanensis (Reuss, 1933), From Gavur Mountain (Gümüşhane), Bi̇lal Kutrup, Ufuk Bülbül, Nurhayat Yilmaz Jan 2005

On The Distribution And Morphology Of The Steppe Viper, Vipera Eriwanensis (Reuss, 1933), From Gavur Mountain (Gümüşhane), Bi̇lal Kutrup, Ufuk Bülbül, Nurhayat Yilmaz

Turkish Journal of Zoology

Vipera eriwanensis (Reuss, 1933), known only from the localities of the eastern Aras River in Turkey, was morphologically examined and compared with the related species on the basis of one additional specimen from Gavur mountain (province Gümüşhane), situated outside the known localities. This information changed our knowledge of the total distribution of V. eriwanensis, clearly showing that this taxon has expanded its range at least 210 km to the west in eastern Turkey. Furthermore it differs from V. eriwanensis reported from Turkey, Armenia and Azerbaijan in having a lower number of mid-body scales and loreals, and a higher number of …

Types Of Areas And The Origin Of Black Flies Fauna In Mongolia (Diptera: Simuliidae), Josef Halgoš

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The survey of Mongolian Black Flies species (Diptera: Simuliidae) is given in the presented work. The classification based on Emelyanov (1974) and Gorodkov (1984) appeared to be as most advantageous one. Black Flies species found on the Mongolian territory up to now were classified according to the character of their distribution among 5 groups: Holoarctic species (7 species), Eurasian (15), Eastern Palaearctic (20), Turanian-Mediterranean (7), Mongolian endemic species (8). Individual groups are divided according to the type of area into smaller subgroups. The zoogeographical analysis has shown big similarity with Black Flies zoogeography in Siberia and Far East (in percentage …

Temperature Regulation And The Constraints Of Climate In The Eared Grebe, Hugh I. Ellis, Joseph R. Jehl Jr Feb 2003

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 …

A Geographic Information System To Monitor Nest Distributions Of Double-Crested Cormorants And Black-Crowned Night-Herons At Shared Colony Sites Near Toronto, Canada, S. Jarvie, H. Blokpoel, T. Chipperfield Dec 1997

A Geographic Information System To Monitor Nest Distributions Of Double-Crested Cormorants And Black-Crowned Night-Herons At Shared Colony Sites Near Toronto, Canada, S. Jarvie, H. Blokpoel, T. Chipperfield

Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest

In the early 1990’s, it became apparent that the rapid colonization of Tommy Thompson Park on Lake Ontario near Toronto by double-crested cormorants (Phalacrocorax auritus) would eventually affect the existing colonies of blackcrowned night-herons (Nycticorax nycticorax) owing to competition for nest sites and destruction of nest trees. As a result, monitoring of these two species was expanded in 1992 by individually marking all nest trees (using permanent metal tree tags) and by recording the numbers of heron and cormorant nests for all nest trees. In 1996, professional surveyors determined the exact locations of nest trees. We have developed …
