Morphological characteristics of the mountain frogs were given in detail and compared with the specimens from Uludağ where the type locality of Rana macrocnemis. Key words: Rana macrocnemis, new locality, distribution, Western Anatolia, Turkey Introduction Rana macrocnemis was first described from Uludağ, Bursa, Turkey (Boulenger 1885). Following year, another mountain frog (Rana camerani) was described from Georgia (Tabatskuri Lake and Akhalkalaki) (Boulenger 1886). The occurrence of the latter taxon in Anatolia (Erciyes Mountain, Kayseri) was given by Werner (1902). The distribution sites of the moun- tain frogs cover Anatolian and Caucasus Mountain chains with isolated population on the Strizhament Mountain in the Stavropolskii Region of Russia from sea level to 3.000 m a.s.l. (Kuzmin et al. 2009). The date they have been described until recently, various researchers (Boulenger 1898, Werner 1902, Lantz & Cyren 1913, Bodenheimer 1944, Mertens 1952, Başo- ğlu & Hellmich 1958, 1970, Eiselt 1965, Baran 1969, Eiselt & Schmidtler 1971, Ishchenko 1978, 1987, Baran & Atatür 1986, Tarknishvili et al. 1999, Tarknishvili & Gokhelashvili 1999, Picariello et al. 1999, Arıkan et al. 2001, Veith et al. 2003a, b, Çevik et al. 2006) expressed different opinions about the taxonomic status of the Anatolian and Caucasus mountain frogs. More recently, studies covering new locality records of the mountain frog were conducted in Turkey (Düşen et al. 2002, Baran et al. 2007, Afsar et al. 2013, Afsar et al. 2015). The main goal of this study is to present a detailed morpho- logical description of the specimens of mountain frog col- lected from new localities in the Western Anatolia. Figure 1.

The morphometric measurements used here (TD/HL)*100, (TD/ID)*100 and (MTL/TL)*1000] were used to test 40 Ç. Ilgaz et al. for similarities and differences. Indices and ratios were used due to an uncertainty regarding age groups and because it was not known whether growth was isometric or not. Data were examined for con- formation to assumption of normality (the Kolmogorov-Smirnov test) and homogeneity (Fmax). The morphometric indices that showed differences between sexes were excluded from further analysis. Later on, one-way ANOVA was applied to the morphomet- rics of the 2 populations according to morphometric indices and ra- tios that did not show sexual dimorphism between sexes.

It is based on a first draft by WCMC in 1998. Except for Birds (Birdlife International, 1994), no assessment is yet available on the conservation status of Vertebrate species at European level, while Red Books exist at national level in almost all European countries. On the other hand, a global list of threatened species is published and maintained up-dated by IUCN according to well defined criteria (IUCN, 2000). The present assessment is a first attempt to identify the most threatened Vertebrates species at European level, building upon a first analysis of the list of globally threatened species present in Europe (WCMC, 1998) and taking into account the most recent available overviews on European species distribution provided by the various European atlas committees (European Bird Census Council; Societas Europaea Herpetologica, Societas Europea Mammalogica).

We used this approach to determine the age structure of 162 individuals from two Pelophylax caralitanus populations. All individuals exhibited Lines of Arrested Growth (LAGs) in the bone cross-sections and the average age varied between 4.5 and 5.4 years in both Işıklı and Burdur populations. Although intraspecific age structure and sex-specific age structure did not differ signifi- cantly between populations, we found that the Işıklı population had a lower body size in the same age class, had lower growths rates and lower values of survival rates and adult life expectancy than the Burdur population.

July 2011 / Available online: 09. August 2011 Abstract. Age structure and body size of a population of the China Wood Frog (Rana chensinensis) in northeastern China were determined by using skeletochronology. Lines of arrested growth (LAGs) recorded in phalanges were used to estimate the age of adults. Results showed that average age did not differ significantly between males and females. Age at sexual maturity in both sexes was 1 yr. The maximum observed longevity was 5 yrs in males and 4 yrs in females, respectively. Average body size of females was significantly larger than males. A non-significant negative correlation between body size and air temperature was found among the seven populations when the effect of altitude, latitude and age was controlled, suggesting that latitudinal variation in body size of Rana chensinensis across different temperature environment do not follow Bergmann's rule. Key words: skeletochronology, Bergmann's rule, Rana chensinensis, body size, age structure.

If there was something written to my destiny: "Biology / Zoology is not a profession for me, it is my lifestyle. My feelings, approaches, and reactions are coming out of this lifestyle. If you want to learn something, experience it! If you take nature as an example, there is no chance of making a mistake! That is the right way!" ‒ Prof. Dr. Bayram GÖÇMEN.
