Ecological characteristics of Caracal (Caracal caracal) in Türkiye: An isolated Feline population İlemin, Yasin; Koç, Hasan; Yenisey Kaynaş, Burçin Caracal is an adaptive and generalist predator with high ecological tolerance on the other hand it has an isolated population in Türkiye. We investigated the ecological characteristics of caracal (Caracal caracal) in the Mediterranean ecosystems of Southwestern Anatolia (Türkiye) where its population is isolated from other Asian populations. We used field observations and camera trap methodology across a landscape covering 750 km2 to determine the population status, morphology, behavioural characteristics, the status of species in the community, diet and habitat preference of caracal in the region. Caracal density was estimated to be 0,18 caracals/km2. The female home range was estimated to be between 4,1 km2 and 25 km2 whereas the male home range was estimated to be between 5 km2 and 50 km2 or more. Species’ daily activity was determined as cathemeral. Annual activity patterns as well as home range sizes decreased during the dry season. During the wet season, caracal activity as well as home range sizes increased. Vegetation cover was found to be the most important factor affecting habitat use by caracal. A strong negative correlation of 0.7 between caracal occurrence and forest cover indicated that forest cover was the most important factor affecting habitat use by a caracal. Caracal occurrence was also positively correlated with 3 mammal species in the study area, wild boar, European hare and wild goat. Caracal was determined as the dominant carnivore species in the ecosystem. Wild herbivore populations in the study area seem to be influenced by caracal thus resulting in a conspicuous effect on grazing pressures. We conclude that caracal is a keystone species in our ecosystem and plays a vital role in maintaining their integrity. Thus, the conservation of the caracal population is crucial for the conservation of the whole Mediterranean ecosystem.

Manisa Memeli Faunası Üzerine Bir Araştırma İlemin, Yasin This study aimed to identify the mammalian fauna in Manisa and the threats on these species. Field studies were carried out for a total of 45 days in 2018 and 2019. As a result of the survey, 36 different terrestrial and inland water mammal species were identified. Among the existing species, it was determined that especially large mammal and carnivorous species such as Golden jackal (Canis aureus), Wolf (Canis lupus), Brown bear (Ursus arctos), Caracal (Caracal caracal), Wild cat (Felis silvestris), Reed cat (Felis chaus), Striped Hyena (Hyaena hyaena), Roe Deer (Capreolus capreolus), and Indian crested porcupine (Hystrix indica) are under threat. Bat species belonging to the families Rhinolophidae and Vespertilionidae were also found to be under threat. The location and degree of these threats were given and suggestions were proposed to take necessary precautions.

Mortality Record of Caracal and Habitat Loss for Wildcat, Depending on Catastrophic Wildfires of Year 2021 in Southwestern Turkey İlemin, Yasin The fires that occur in Southwestern Turkey in July and August 2021 were recorded as the biggest fires in the history of the Republic for the region. The burned forest area is more than 66 000 hectares. This study aims to evaluate the situation of wildlife after catastrophic wildfires in terms of unique felids of the region: caracal (Caracal caracal) and wildcat (Felis silvestris). Study was conducted using empirical techniques at fire sites in Mugla province of Turkey during eighteen days in August 2021. Two transects were identified for each four fire effected zone as "burned" and "unburned" site. Total distance covered by vehicle transect was 2000 km with four repeated interval during the survey. It has been figured out that wildfires effecting large mammals and felids in two ways as direct (deaths caused by fire) and indirect effect (habitat loss, fire migration and releated deaths). 194 individual recorded as indirectly effected and 11 individual (9 wildboar, 2 Southwest Asian badger) recorded as directly effected by the wildfires. 5 caracal were recorded during fire migration. A caracal carcass was found on highway. The caracal population in the region survived the fires with the least damage. On the other hand, wildcat habitats were completly burned during the fires. Although recolonization after massive wildfires is a natural succession process for many large herbivores and carnivores, Mediterrenaen wildcats of Anatolia could be an exception. They have very isolated and fragile population in Mugla. Wildlife corridors sould be planned to support post-fire succession and wildcat colonisation of burned site. In order to investigate this situation, temporal and spatial habitat use and diet analyzes are planned for caracal and wild cat for the next step.

Element concentration, daily intake of elements, and health risk indices of wild mushrooms collected from Belgrad Forest and Ilgaz Mountain National Park (Turkey) Keskin, Feyyaz; Sarıkürkcü, Cengiz; Akata, Ilgaz; Tepe, Bektaş The aim of this study was to determine the element content of wild edible and inedible mushroom species (Agaricus campestris, Armillaria ostoyae, Boletus reticulatus, Bondarzewia mesenterica, Bovistella utriformis, Cantharellus cibarius, Marasmius oreades, Megacollybia platyphylla, Meripilus giganteus, Neoboletus erythropus, Panellus stipticus, Phaeotremella foliacea, Pleurotus ostreatus, Podoscypha multizonata, Russula aurea, R. chloroides, R. virescens, T. versicolor, Trametes gibbose, and Trichaptum biforme) collected from the Belgrad Forests and the Ilgaz Mountain National Park. Based on the results of elemental analyses, daily metal intake (DMI) and health risk index (HRI) values of edible mushrooms collected from both localities were also calculated. As, Cd, Cr, Se, P, Hg, Cu, Mn, Fe, Zn, Al, Ca, Mg, and K contents of mushrooms were in the ranges of 0.16–3.45, 0.09–2.4, 0.15–2.34, 0.3–8.13, 0.28–11.44, 14.03–37.81, 3.87–108.57, 6.18–149.77, 11.9–776.1, 5.4–317.4, 7.4–355.2, 15.4–3517.3, 266.0–2500.0, and 628.0–24083.0 mg/kg dry weight, respectively. As a result of the DMI and HRI analyses, Cu concentration of B. utriformis (DMI: 46.53 μg/kg body weight/serving, HRI: 1.16) and Cd concentrations of A. campestris (DMI: 0.49 μg/kg body weight/serving, HRI: 1.36), A. ostoyae (DMI: 1.03 μg/kg body weight/serving, HRI: 2.86), B. utriformis (DMI: 0.52 μg/kg body weight/serving, HRI: 1.44), and P. ostreatus (DMI: 0.45 μg/kg body weight/serving, HRI: 1.24) were found to exceed the legal limits determined by authorities. It was concluded that the species collected from the regions in question should be consumed in a controlled manner.
