Age-Dependent Cranial Variations In Mesocricetus Brandti (Mammalia: Rodentia) Distributed In Turkey, Nuri̇ Yi̇ği̇t Jan 2003

Age-Dependent Cranial Variations In Mesocricetus Brandti (Mammalia: Rodentia) Distributed In Turkey, Nuri̇ Yi̇ği̇t

Turkish Journal of Zoology

Animals were assigned to four age groups according to molar wear, field notes and external and cranial measurements. Six days-old animals were referred to newborn, up to 30 days as young and thereafter as adult; animals with very worn molars were considered old. In addition to the statistical differences among age groups, it was determined that the main morphological differences were in the interorbital constriction, the shape of the braincase, the ridges and the position of occipital condyles. While the incisors and the first molars erupted in seven days-old animals, the second and third molars begun to erupt after seven …

Turkish Journal of Agriculture and Forestry

This study estimates a supply model for apricots and an export demand model for dried apricots for Turkey to provide unit-free measure coefficients for better supply and marketing management. Using parameter estimates from the models and sample average data, elasticities of long-run supply, price-yield and export of dried apricots were computed as 0.72, 0.54 and -0.87 respectively. From the price dependent export demand model, the price flexibility of dried apricots was calculated as -0.71.

The Presence Of Mallophaga Species On Wild Partridge In The Elazığ District, Nursel Aksin

Turkish Journal of Veterinary & Animal Sciences

The purpose of this study was to determine the presence of Mallophaga species on wild partridges in the Elazığ region. We inspected 68 partridges for Mallophaga species between November and January from 1996 to 2000. At least one species of Mallophaga was found on 48 partridges. Three species of Mallophaga were found on infested partridges. These species, were Goniodes dispar (Burmeister, 1838), Goniocotes pusillus (Nitzch in Giebel, 1866) and Menacanthus lyali (Rodriguez Caabeiro et al.,1983). These three Mallophaga species have not been reported before in Turkey.

Measuring The Market Power Of The Banana Import Market In Turkey, Seli̇m Adem Hatirli, Eugene Jones, Ali̇ Riza Aktaş Jan 2003

Measuring The Market Power Of The Banana Import Market In Turkey, Seli̇m Adem Hatirli, Eugene Jones, Ali̇ Riza Aktaş

Turkish Journal of Agriculture and Forestry

Banana production in Turkey represents a small fraction of that required to meet domestic consumption. Domestic consumption totaled 188,000 t in 2000, whereas production amounted to just 64,000 t, or 34% of consumption. The gap between consumption and production is made up by imports and 5 multinational firms control the flow of more than 80% of the global banana trade. Given this firm dominance in the world trade of bananas, oligopoly theory would suggest the presence of underlying structural forces that could facilitate price-enhancing market power. As such, this study develops an integrated trade and new empirical industrial organization (NEIO) …
