Analyses Of Human-bear Conflict In Yusufeli, Artvin, Turkey

Ambarli, Huseyin 01 February 2006 (has links) (PDF)
Increasing levels of conflict between brown bears and rural people have been reported for Yusufeli (Artvin, Turkey). This study aimed to document the conflict, understand human attitudes and responses, determine local habitat use and daily activity patterns of bears, and evaluate available damage prevention techniques. The study was conducted within landscapes at different scales, ranging from a core area defined by a large valley system to the whole of Artvin Province. Data on close encounters, injuries and damages caused were collected through government records, published literature and open-ended interviews with the locals. Bear presence and activity were monitored through various techniques, including the capture and radio-collaring of one individual. Population density was found to range between 11-27 adult bears/100 km2. Bear activity increased during hyperphagia, with many daytime observations. Interviews (n=67) showed that almost all (95%) locals believed that bears have become more of a problem lately. Only 6% supported full protection while 38% conditionally accepted it. On more than two-thirds of close encounters, the bear and person(s) involved departed without any harm. Rare bear attacks on humans, usually provoked, sometimes caused non-fatal injuries. Several bears were found to be shot and killed within the study area in 2002-2005. Damages were mostly in late summer on field crops and orchards, and in spring on beehives. Precautions taken by villagers differed in effectiveness against bears. Bears caused a minimum of US$21,500 worth damages annually at Yusufeli County. Implementation of modern techniques of exclusion and scaring would reduce human-bear conflict in the region.

Effects of Dietary Plasticity and Landscape Heterogeneity on Brown Bears

Stutzman, Lindsey 06 May 2017 (has links)
The brown bear (Ursus arctos) is a generalist omnivore that occupies diverse habitats and displays high levels of behavioral plasticity. Plasticity in foraging behavior can result in variable diets across a population, and allow individuals to use a greater variety of resources. The distribution of food in space and time may also be an important factor in determining brown bear resource selection as it can greatly influence foraging efficiency. Our objectives were to determine if seasonal brown bear home ranges were influenced by temporal availability and spatial distribution of resources and if deviation from an optimal diet influenced brown bear body condition. Understanding how the spatial and temporal distribution of food influences brown bear space use and the relationships between behavioral plasticity and the ability of populations to persist in dynamic environments could provide additional insights into the eco-evolutionary advantages of variable foraging behavior and ultimately population resilience.
