Plastic behavioral adaptation to human activities can result in the enhancement and establishment of distinct behavioral types within a population. Such inter-individual behavioral variations, if unaccounted for, can lead to biases in our understanding of species' feeding habits, movement pattern, and habitat selection. We tracked the movements of 16 adult brown bears in a small and isolated population in northeast Turkey to i) identify inter-individual behavioral variations associated with the use of a garbage dump and ii) to examine how these variations influenced ranging patterns, movements behavior and habitat selection. We identified two remarkably distinct behavioral types: bears that regularly visited the dump and remained sedentary year-round, and bears that never visited the dump and migrated 165.7 ± 20.1 km (round-trip mean cumulative distance ± SE) prior to hibernation to search for food. We demonstrated that during migratory trips, bears moved more rapidly and were less selective in habitat choice than during the sedentary phase; during the migration phase forest cover was the only important environmental characteristic. Our results thus reinforce the growing evidence that animals' use of the landscape largely changes according to movement phase. Our study shows that anthropogenic food resources can influence food habits, which can have cascading effects on movement patterns and hence habitat selection, ultimately resulting in the establishment of distinct behavioral types within a population. Identification and consideration of these behavioral types is thus fundamental for the correct implementation of evidence-based conservation strategies at the population level.

“…The fragmentation of forest, lack of prey species, illegal hunting and car crashes represent significant threats to this species. Little is known about the distribution and ecology of the Eurasian lynx in eastern Turkey (Chynoweth et al 2015). The Eurasian lynx eats a wide range of prey including ungulates, gamebirds and small mammals.…”

Echinococcus multilocularis in a Eurasian lynx (Lynx lynx) in Turkey

et al. 2018

Echinococcus multilocularis is the causative agent of alveolar echinococcosis (AE), one of the most threatening zoonoses in Eurasia. Human AE is widespread in the Erzurum region of Turkey, but the situation of the disease in intermediate and definitive hosts is unknown. A Eurasian lynx (Lynx lynx) was killed in a traffic accident in the north of Erzurum, and was taken to our laboratory. Sedimentation and counting technique (SCT), DNA isolation and polymerase chain reaction (PCR) analysis were performed. The SCT results showed that the lynx was infected with E. multilocularis with a medium (745 worms) worm burden. The DNA of adult worms obtained from the lynx was analyzed with a species-specific PCR, and the worms were confirmed to be E. multilocularis by 12S rRNA gene sequence analysis. This is the first report of E. multilocularis from Eurasian lynx in Turkey.

“…The raccoon dog has been mentioned as a potential prey for lynx (Lavrov, 1971). Even though this is positive for the Caucasian lynx (Lynx lynx dinniki) and gray wolves (Canis lupus) living in this study area with relatively low mammalian prey availability (Chynoweth et al, 2015;Capitani et al, 2016), the raccoon dog's capacity as an expanding nonnative species, its ability to cope with new environments, its capacity as an important host for rabies, and its omnivorous feeding strategy that results in raccoon dogs preying on and competing with other native mammals combine to make it an overall threat to Turkey's forest ecosystems.…”

The raccoon dog (Nyctereutes procyonoides) was recorded for the first time in Turkey on May 10, 2019, and June 5, 2019, in the same location after 4668 nights of camera trapping in the forests of the Sarıkamış region and Allahuekber Mountains in eastern Turkey. It was recorded in a Scots pine (Pinus sylvestris) forest at 2340 m above sea level with extensive snow cover. Given that the nearest known population is in the forests of Georgia approximately 105 km away, there may already be a viable population in Turkey. As an omnivorous species with a high adaptive ability and high reproductive potential, the raccoon dog has strong dispersal capability. It is considered an invasive species in Europe and there are some ongoing eradication activities in several countries. Therefore, we strongly advise that the raccoon dog in Turkey be evaluated as an invasive species and that the relevant authorities conduct extensive research and any necessary management, especially where the habitat and local climate are more favorable for the species' reproduction and range expansion.
