The Taxonomic Status Of Triturus Vulgaris(Linnaeus, 1758) Populations In Western Anatolia, Turkey, Kurtuluş Olgun, İbrahi̇m Baran, Cemal Varol Tok Jan 1999

The Taxonomic Status Of Triturus Vulgaris(Linnaeus, 1758) Populations In Western Anatolia, Turkey, Kurtuluş Olgun, İbrahi̇m Baran, Cemal Varol Tok

Turkish Journal of Zoology

A total of 179 (97 males, 82 females) Triturus vulgaris specimens collected during the breeding season from Western Anatolia (Efes, Ayvacık, Lapseki, Karacabey, Gemlik) and European Turkey (Bolayır) was examined. The morphological and the statistical evaluations showed that the Western Anatolian (except Efes) and the Thrace populations are similar. The West Anatolian populations, therefore, should be included in the nominate subspecies, T.v. vulgaris. The Efes specimens were found to be different from specimens of Ayvacik, Lapseki and Gemlik especially in terms of body measurements. The explanation of the taxonomic status of the Efes population will be possible with the material …

The Black Sea Zooplankton: Composition, Spatial/Temporal Distribution And History Of Investigations, A. V. Kovalev, V. A. Skryabin, Yu. A. Zagorodnyaya, Feri̇t Bi̇ngel, Ahmet Erkan Kideyş, U. Ni̇ermann, Z. Uysal Jan 1999

The Black Sea Zooplankton: Composition, Spatial/Temporal Distribution And History Of Investigations, A. V. Kovalev, V. A. Skryabin, Yu. A. Zagorodnyaya, Feri̇t Bi̇ngel, Ahmet Erkan Kideyş, U. Ni̇ermann, Z. Uysal

Turkish Journal of Zoology

Investigations into the composition, spatial and temporal distribution of the Black Sea zooplankton were reviewed in context with its historical development. The review comprises the main zooplankton studies published by the riparian countries of the Black Sea beginning with the earliest faunistic publications in the 1860s and 1870s up to the recent multinational ecosystem investigations carried out within the framework of the NATO-TU-Black Sea Project. The reviewed material covers a wide subject range of zooplankton investigations from descriptive studies to distribution and the production mechanisms in the ecosystem. The main findings of recently performed large scale investigations into the horizontal …

Contribution To The Taxonomy, Distribution And Karyology Of Martes Foina(Erxleben, 1777) (Mammalia: Carnivora) In Turkey, Nuri Yi̇ği̇t, Ercüment Çolak, Mustafa Sözen, Şakir Özkurt Jan 1998

Contribution To The Taxonomy, Distribution And Karyology Of Martes Foina(Erxleben, 1777) (Mammalia: Carnivora) In Turkey, Nuri Yi̇ği̇t, Ercüment Çolak, Mustafa Sözen, Şakir Özkurt

Turkish Journal of Zoology

In this preliminary study, nine Stone Martens were recorded from different localities in Turkey. Their morphological characteristics were found to be consistent with previously published papers. However, the throat patches of Turkish Stone Martens show variations with respect to shape. In addition, it was determined that the morphologic and biometric characteristics of Turkish samples were consistent with those of M. f. syriaca. According to the karyological findings, the diploid number of chromosomes and the fundamental number were 38 and 76, respectively.

Distribution And Habitats Of Forked Aster (Aster Furcatus), A Threatened Wisconsin Plant, Lawrence A. Leitner, James A. Reinartz, Donald H. Les Oct 1991

Distribution And Habitats Of Forked Aster (Aster Furcatus), A Threatened Wisconsin Plant, Lawrence A. Leitner, James A. Reinartz, Donald H. Les

Field Station Bulletins

We describe the locations and habitat characteristics of 10 of the 14 known populations of Aster furcatus in Wisconsin. We were unable to identify any particularly unusual features of A. furcatus habitats which could be related to its rarity. The rarity of forked aster is probably not related to specialized habitats, but is most likely the result of requirements for moderate disturbance, inability to withstand competition, poor reproduction from seed, and low genetic variance.

The Distribution Of Sarracenia Purpurea (Pitcher Plant) In Southeastern Wisconsin Fens: The Influence Of Ph And Nutrients, Teresa A. Golembiewski, Forest Stearns Apr 1987

The Distribution Of Sarracenia Purpurea (Pitcher Plant) In Southeastern Wisconsin Fens: The Influence Of Ph And Nutrients, Teresa A. Golembiewski, Forest Stearns

Field Station Bulletins

Temperature, pH, alkalinity, total-N, total-P, K, Na, Ca and Mg levels were measured in groundwater at the Pickerel Lake and Ottawa Lake calcareous fens and the Cedarburg Bog patterned fen. The two calcareous fens were similar in all chemical characteristics. Alkalinity, pH and Mg were significantly lower in the patterned fen when compared to the calcareous fens, while the other chemical parameters were similar. Each of these southeastern Wisconsin fens supported Sarracenia purpurea (pitcher plant). When the characteristics of the groundwater of the areas that supported S. purpurea were compared with those of areas that did not support S. purpurea, …

Distribution And Current Status Of The Threatened Dismal Swamp Southeastern Shrew, Sorex Longirostris Fisheri, Robert K. Rose, Roger K. Everton, Thomas M. Padgett Jan 1987

Distribution And Current Status Of The Threatened Dismal Swamp Southeastern Shrew, Sorex Longirostris Fisheri, Robert K. Rose, Roger K. Everton, Thomas M. Padgett

Biological Sciences Faculty Publications

The Dismal Swamp southeastern shrew, Sorex longirostris fisheri, was given "Threatened" status by the U.S. Fish and Wildlife Service in 1986 because of its limited distribution and the potential threat of interbreeding with the nearby upland subspecies, Sorex l. longirostris. Known from about 20 specimens collected before 1980 and a few dozen taken since then, "fisheri" seems to have morphologically diverged from the smaller upland "longirostris" in association with the development of the Dismal Swamp. The detection of southeastern shrews that are intermediate in size between the two subspecies, coupled with the location of these collection sites on …

Summer Distribution And Food Habits Of Microtus In The Logan Canyon Area, Utah, James B. Monroe May 1969

Summer Distribution And Food Habits Of Microtus In The Logan Canyon Area, Utah, James B. Monroe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Field work for the study was conducted in Logan Canyon and the valley at the base of that canyon in Cache County, Utah, during the three summer months of both 1968 and 1969, Microtus pennsylvanicus, found only in the valley, inhabits wet marshy areas. Microtus longicaudus is found in mixed deciduous woods a long the Logan River in the canyon. Microtus richardsoni, which occurs only at the higher elevations, inhabits the subalpine meadows. Microtus montanus inhabits mesic grassy fields in both the valley and Logan Canyon and also inhabits a mixed deciduous woods and tall canary grass ( …
