Birds Of Lake Beyşehir (Isparta-Konya), Mehmet Ali̇ Tabur, Yusuf Ayvaz

Turkish Journal of Zoology

The Lakes Region contains wetlands important for Turkey's biodiversity. In this study conducted from October 2000 to September 2002 at Lake Beyşehir, 181 bird species were observed. Sixty-one residents, 43 winter migrants, 51 summer migrants, and 26 transit migrants were observed. According to the IUCN, Pelecanus crispus, Phalacrocorax pygmeus, Aythya nyroca, Haliaeetus albicilla and Falco naumanni are threatened and the other 176 species observed are not. According to the statistical data, Cuculiformes, Strigiformes and Caprimulgiformes were less common, while Passeriformes was the most common order in the study in terms of bird species. Among the other lakes in the Lakes …

An Allometric Comparison Of Microsomal Membrane Lipid Composition And Sodium Pump Molecular Activity In The Brain Of Mammals And Birds, Anthony J. Hulbert, Paul Else, Nigel Turner

Faculty of Health and Behavioural Sciences - Papers (Archive)

Previous research has shown that the lipid milieu surrounding membrane proteins may be an important factor in determining their activity. To investigate this we have examined sodium pump molecular activity and microsomal membrane lipid composition in the brain of five mammalian and eight avian species ranging in size from 30 g mice to 280 kg cattle and 13 g zebra finches to 35 kg emus, respectively. Sodium pump (Na⁺,K⁺-ATPase) activity was higher in the smaller species and showed a significant allometric decline with body mass in both the mammals (μmol P_i h^-1 mg wet …

The Geological Context Of Middle Pleistocene Crater Lake Deposits And Fossil Birds At Ulupau Head, Oahu, Hawaiian Islands, Paul Hearty, H. F. James, S. L. Olson

Faculty of Science - Papers (Archive)

Pleistocene lake deposits in Ulupau Crater on Oahu contain the oldest fossil bird remains known from the Hawaiian Islands. These fossils are important for documenting evolutionary rates in a variety of lineages of land and water birds from the islands. Detailed stratigraphic analysis reveals distinct cycles of deposition involving interbedded lacustrine deposits, colluvium, and paleosols. The volcanic basin was breached by marine erosion prior to the peak of the last interglaciation (marine isotope stage or ‘MIS’ 5e) over 125 ky ago, constraining the age of the lake sediments to the middle Pleistocene. The three cycles of deposition (Units III, IV, …

Landscape Ecology Of Birds On Mount Leconte, Great Smoky Mountains National Park, Andreas P. Damalas

Biological Sciences Theses & Dissertations

Landbirds form a significant component of wildlife resources in the Great Smoky Mountains National Park. The present study explored how forest structure and composition of deciduous-coniferous ecotones influenced diversity, richness, and relative abundance of bird species and how bird species responded to the spruce-fir community.

Using a form of the variable-circular plot method, I conducted audio-visual censuses of diurnal birds on Mount LeConte. I established 212 geo-referenced census points on six trails, which were used as gradient-oriented transects (gradsects). I measured habitat characteristics at the same census points. I used forest community types for each point on gradsects to delineate …
