Article | 2009 | Turkish Journal of Zoology33 ( 1 ) , pp.93 - 102

Multivariate Morphometric and Spatial Autocorrelation Analyses were performed to determine the morphometric variation in Apis florea colonies representing 13 localities from 4 states on the coastal north-south diagonal in Iran. New morphometric characters (hind wing length, hind wing width, and hind wing angles) were also measured to determine the usefulness of these characters for Apis florea. Analysis of variance of new morphometric characters showed that 7 out of the 8 hind wing variables displayed statistically significant differences among populations (P < 0.05). The scatter plot from Canonical Variate Analysis revealed that th . . .e colonies from north (Ilam, Khuzestan, and Bushehr states) showed an overlapping distribution. The colonies from south (Hormuzgan state) formed a non-overlapping distant cluster. Based on the spatial autocorrelation analysis, 14 correlograms were significant for morphometric characters (According to the Bonferroni criterion). Six characters (CuB, C.Ind, HWW, B4, D7, and I13) showed clinal type correlogram. © TÜBİTAK Daha fazlası Daha az

Acomys cilicicus is endemic to Turkey and known from a very restricted area. The exact distribution of the species was not known up to now and the IUCN status of the species was Data Deficient (DD). To determine the exact distribution area of the species, 39 localities within the historical distribution were surveyed by using 3243 Sherman traps between 2013 and 2016. Turkish spiny mouse samples were obtained from 14 of these 39 localities and the current distribution of the species was determined. We found that the Turkish spiny mouse has two isolated populations in the area between Silifke and Erdemli with a total distribution area . . . of about 104.5 km 2 , extending from sea level up to 510 m a.s.l. Population trend estimates showed a steep decline in the last 20 years from 21.42 to 2.75 as trap night index value. These data, along with the decline in habitat quality and continuing threats to the species, merit an IUCN status of Critically Endangered (CR). The main threats for this species are habitat loss due to urbanization, new motorway construction, stone quarry development, conversion of Mediterranean shrublands into agricultural fields, and afforestation. For conservation purposes, a species protection action plan is necessary immediately. Acomys cilicicus is endemic to Turkey and known from a very restricted area.

Article | 2006 | Turkish Journal of Zoology30 ( 2 ) , pp.205 - 219

Körfare Spalax leucodon Nordmann, 1840 üzerinde yapılan bu araştırmada Kastamonu çevresindeki 18 lokaliteden 98 örneğin karyolojisi ve morfolojisi incelendi. Kastamonu çevresinden incelenen körfare populasyonlarının 2n = 54, NF = 72; 2n = 56, NF = 74; 2n = 58, NF = 74; 2n =60, NF = 74 değerlerine sahip oldukları belirlendi. Bu karyolojik sonuçlara göre kromozom morfolojileri bakımından Kastamonu çevresinden belirlenen 2n = 56, 2n = 58 ve 2n = 60 kromozom sayıları Türkiye'deki Spalax leucodon için yeni değerlerdir. Bu populasyonların diploid kromozom sayıları Türkiye'den coğrafik olarak uzak bazı bölgelerde daha önce belirlendiği içi . . .n bu çalışmada belirlenen değerleri aynı kromozom sayısına ancak farklı kromozom morfolojilerine sahip diğer formlardan ayırmak için 2n = 56N, 58N ve 60N olarak isimlendirildiler. t-testi analizleri sonucunda bütün kromozomal formların diploid kromozom sayıları yanında çok sayıda karakter ölçüsü bakımından da birbirlerinden ayrılabilmesi Spalax kromozomal formlarının ayrı biyolojik türler olarak değerlendirilmesi gerektiği şeklindeki yaklaşımı desteklemektedir. The karyotypes and morphology of 98 specimens of the subterranean mole rat Spalax leucodon Nordmann, 1840 across 18 localities in and around Kastamonu province were analysed. It was determined that S. leucodon has 2n = 54, NF = 72; 2n = 56, NF = 74; 2n = 58, NF = 74; 2n =60, NF = 74 in the populations from the Kastamonu region. According to these karyological findings based on chromosome morphology the diploid chromosome numbers of 2n = 56, 2n =58, and 2n = 60 determined here are new for Spalax leucodon in Turkey. Because diploid numbers of these populations were formerly found from geographically distant localities in Turkey, they were given as 2n = 56N, 58N, and 60N, to differentiate them from the other forms having the same diploid chromosome numbers but different chromosome morphology. As a result of t-test analysis, separation of all chromosomal forms from each other beside 2n values by many character measurements supported the opinion that each of the chromosomal forms of Spalax should be evaluated as good biological species Daha fazlası Daha az

Talpa davidiana is the least known species of the genus Talpa, and the karyotype of this species is still unknown. Its distribution records are also very scattered. The karyological, cranial, and pelvic characteristics of 2 samples from Ki{dotless}zi{dotless}ldag in Adana Province were analyzed for the first time. It was determined that T. davidiana has 2n = 34, NF = 66, and NFa = 62. The X chromosome was large and metacentric and the Y chromosome was dot-like acrocentric. The 2 samples are different from each other, and from previous T. davidiana records, in terms of their lower incisor and premolar numbers. Unique among the T. dav . . .idiana samples examined to date, 1 of the samples studied here had 2 premolars on the lower jaw half instead of 3. In contrast to the literature, 1 sample has a europeoidal pelvis, and the other has an intermediate form. T. davidiana has been recorded from 6 localities from the area between Hakkari and Gaziantep provinces in Turkey. The Ki{dotless}zi{dotless}ldag high plateau of Adana was a new distribution locality and the most western for T. davidiana. The nearest known locality is Meydanakbes village, and it is almost 160 km away, as the bird flies, from Ki{dotless}zi{dotless}ldag high plateau. The new distribution record from Ki{dotless}zi{dotless}ldag high plateau implies that the mountain range between Tatvan and Adana may include some undiscovered samples. © TÜBİTAK Daha fazlası Daha az

Bu çalışmada; Spermophilus citellus ve S. xantophrymnus'ların ekolojisi, üremesi ve davranışı üzerine 4 yıl süreli arazi ve laboratuvar çalışmaları yapılmıştır. S. citellus Trakya' da yarı kurak step alanlarda yayılmaktadır. S. xantophrymnus Anadolu'da yarı kurak steplerde habitatını Meriones tristrami, Mesocricetus brandti, Allactaga williamsi, Microtus spp. gibi nokturnal türlerle paylaştığı tespit edildi. Arazide S. xantophrymnus'ların yuva yapıları araştırıldı. Arazide tek tek yuvalanmalarına karşın küçük sosyal kolçniler oluşturdukları, kısık, keskin ve tiz sesler çıkararak birbirleriyle haberleştikleri belirlendi. S. xantophry . . .mnus'un hibernasyon periyodu Ağustos ta başlayıp Şubat sonlarında sona erdiği belirlenmiştir. Laboratuvar gözlemlerinde birbirlerine karşı toleranslı oldukları, arazi ve laboratuvar gözlemlerinde S. citellus ve S. xantophrymnus'ların senede 1 kez doğum yaptığı, bu doğumlarda S. citellus'te yavru sayısının 3, S. xantophrymnus'ta ise 4 olduğu, yavruların doğum ağırlığının ortalama 5-g olduğu, kürklenmenin 15-17. günlerde tamamlandığı, gözlerin 22-25 günlerde, kulakların 30 günde açıldığı ve örneklerin doğumdan sonra 2. ayın sonuna doğru sütten kesildikleri belirlendi. Edirneden yakalanan örneğin doğurduğu 2 yavrunun dış vücut ölçüleri 4 ay sonra erişkin ölçülerine ualştığı tespit edilmiştir. Field and laboratory investigations on the ecology, reproduction and behavior of Spermophilus citellus and Spermophilus xantophrymnus were performed over a period of 4 years. Both S. citellus and S. xanthophrymnus are diurnal species and occupy semiarid steppe areas in Turkish Thrace and Anatolia, respectively. Distribution of the former species is confined to restricted steppe areas in Turkish Thrace whilethe, latter lives on the Anatolian steppe, and is sympatric with Meriones tristami, Mesocricetus brandthi, Allactaga williamsi and Microtus spp. The burrows of both species have one entrance, and are built separately in the field. They constitute small social colonies and communicate with each other by emitting hoarse, sharp and shrill sounds. S. xantophrymnus enterrs hibernation in August and emerges in February. It was observed that they were tolerant of each other. Based on field and laboratory studies S. citellus and S. xantophrymnus give birth once a year. The litter size was at 3 for the former species, and 1 -4 for the latter. Average weight at birth was 5 g for both species. Newborns of both species became hairy at 15-17 days, their eyes opened at 22 -25 days, and their ears at 30 days and offspring were weaned at the end of the second month after birth. The external characters of 2 babies from Edirne attaned those of adults 4 months after birth Daha fazlası Daha az
