Çanakkale Onsekiz Mart University Terzioglu Campus was built on an area with different heights and different habitats. The aim of this study was to determine the spider species fauna which were distributed in the campus area due to the lack of any detailed study on spider fauna of the campus area. In this study, the spider fauna of the Terzioglu Campus area of Çanakkale Onsekiz Mart University was investigated between September 2018 and July 2019. The spiders were collected by pitfall traps, sifting and hand aspirators. A total of 86 spider species belonging to 30 families were determined. The most common species in the study area were Amaurobius erberi (Keyserling, 1863) and Pisaura mirabilis (Clerck, 1957).

Along with the literature information obtained from previous studies, the determination of species in herpetofauna studies gives information about the herpetofauna of the research area. Researching the herpetofauna of regions is very important in terms of conservation of species, revealing biodiversity, identifying possible threats, and determining the preventitive measures to be taken against these threats. The study area is the southwestern coastal regions of Canakkale, which is also the westernmost coast of Anatolia. This area consists of the localities of Ahmetce, Sazli, Kozlu, Behram, Bektas, Koyunevi, Babakale, Gulpinar, Tuzla, Kosedere, and Tavakli. Because it has the potential to be a coastline separated by the end of the Kaz Mountains, this study area has different habitats and has the potential to host species that exceed isolation of the Kaz Mountains. In this study, the amphibian and reptile diversity of terrestrial and aquatic areas along the coast of Southwest Anatolia starting from the end of the Kaz Mountains, which is the habitat preferences of the species, and the effects of environmental and anthropogenic factors on the herpetofauna of the region were investigated. A total of 5 amphibian species and 16 reptile species have been identified in the southwestern coastal areas of Canakkale, and the Testudo graeca species are vulnerable according to the IUCN categories.

To determine how climate factors influence age, body size and sexual size dimorphism (SSD) in the Mediterranean region, we generated data on age and body size of the European Treefrog, Hyla arborea, in three Turkish populations with a latitudinal gradient. We estimated age structure (total ), using skeletochronology. Mean body size of both sexes was smaller in a southern population (Antalya) than in northern populations (Çanakkale and Rize) with female-larger SSD in the northern populations. A positive correlation was found between age and body size in each sex of all the populations, save the Antalya females. Since amphibian growth is reduced after maturity but continues towards the asymptotic size, interpopulation size differences may partly be explained by differences in longevity with four years in Antalya and five years in the other two populations. Comparing age and body size in three Turkish populations with those in three different populations (Greece, Switzerland and Germany) from the literature, there was a trend of South-to-North increase in body size with increased latitude and decreased temperature and aridity. The same trend occurred also in age structure (e.g., age at maturity/first reproduction, longevity). These results suggest that a difference in age structure between populations is a main factor for the geographic variation in body size of this species.

This study examined the effect of variations in the water characteristics (dissolved oxygen, pH, conductivity and temperature) of the biotopes of freshwater turtles (Emys orbicularis and Mauremys rivulata) collected from different localities in Canakkale, Turkey on the blood parameters and put forward the variations in blood parameters for survival during wet and dry periods. According to the water quality of their biotopes, differences were detected in the erythrocyte and leukocyte counts of the species E. orbicularis and in the erythrocyte and leukocyte counts as well as in the MCV (mean cell volume) and MCH (mean cell hemoglobin) values in M. rivulata. In the species E. orbicularis, differences were detected in the biochemical sense in total protein and urea quantities between dry and wet periods.

Wetlands are ecosystems where a high level of biodiversity is found. Being a suitable medium for the nourishment, reproduction, and accommodation of many species of living creatures, wetlands are museums of natural riches, not only of the country where they are located but also of the whole world. Kavak Delta, one of the most important wetlands of Turkey, with coastal dunes and halophilic vegetation as well as being on the north–south bird migration route, provides not only opportunities for coastal tourism but also offers substantial potential for ecotourism. During observations, bird species, especially of the orders Anseriformes, Falconiformes, and Charadriiformes, were identified. Some 14 orders, 39 families, and 124 bird species were spotted in the delta. Also, dune and halophilic plants constitute a rich flora in the delta. In this study, the potential for ecotourism and opportunities for coastal tourism in the area are outlined. Within this context, besides ecotourism activities, such as b...

Conventional taxonomic treatment has resulted in uncertainty as to the taxonomic status of the two subspecies Bufo bufo spino sus and B. b. verrucosissimus in Turkey. Blood‐serum proteins of the B. bufo specimens from Manyas and Camhhemsin were com pared qualitatively and quantitatively by polyacrylamide‐disc elec‐trophoresis and densitometry. The Authors found no significant differences between the blood‐serum proteins of the two popula tions examined, and therefore recommend that B. b. verrucosis simus be synonymized with B. b. spinosus.

The present study compares the blood serum proteins of populations of the Lacerta laevis complex from northern Cyprus and southern Turkey (Adana) by polyacrylamide-disc electrophoresis. There are discernible differences between the electropherograms of blood serum proteins of the two populations. In the light of these differences, it would be appropriate to accept the northern Cyprus population as a distinct species, Lacerta troodica, as suggested previously by BUDAK & GOCMEN (1995).

WOS: 000342305800009 To understand the effects of island and mainland on life history traits (e. g. longevity, age at maturity, body size and body mass) of the smooth newt Lissotriton vulgaris (Linnaeus, 1758), we generated data on age and body measurements for an island (Bozcaada) and a mainland (Canakkale) population in northwestern Turkey. Age was determinated by skeletochronology. the maximum life span was 4 years in the island population and 5 years in the mainland population. Age at maturity was estimated to be 2-3 years for both sexes and the populations. While mean snout-venth length (SVL) was calculated as 35.56 mm for females and 31.95 mm for males in the mainland population, it was found to be 32.83 mm for females and 31.78 mm for males in the island population. Females from the mainland population were found to be significantly larger and heavier than those of the island population. A significant positive correlation was found between SVL and age for only males in the mainland population. Unexpectedly, age was not correlated with body size for the island individuals. Since there were hardly any demographic studies on any Urodela species comparing island and mainland populations, in this paper we contribute to the literature on this subject.
