Litter sizes of brown bears in the Central Alborz Protected Area, Iran

  title={Litter sizes of brown bears in the Central Alborz Protected Area, Iran},
  author={Bagher Nezami and Mohammad S. Farhadinia},
Abstract Although smaller than 4,000 km2, the Central Alborz Protected Area (CAPA) is one of the main habitats of brown bear (Ursus arctos) in Iran. During August 2005 to September 2009, we gathered data through direct observations of bears, identifying individual bears by means of age, sex, color, and behavior. We observed bears on 115 occasions. Mean size of cub litters was 2.00 (SE  =  0.20, n  =  13) and varied from 1 to 3. We speculate that low occurrence of meat in food items of the bears… 

Litter size and basic diet of brown bears (Ursus arctos, Carnivora) in northeastern Turkey

Abstract Brown bears (Ursus arctos) are the largest among terrestrial mammals and are at the center of most human-wildlife conflicts, but there has been little ecological research on the species in

The brown bear Ursus arctos population in Lar Wildlife Refuge, northern Iran

The results suggested that there were few brown bears in the LWR, that they are not resident in the Refuge, and that they come from an adjacent protected area, Central Alborz Protected Area (CAPA), perhaps to feed on spawning brown trout Salmo trutta.

Brown Bear (Ursus arctos) habitat suitability modelling in the Alborz Mountains

Brown bear is the largest carnivore in Iran and is distributed the throughout the mountainous area of the country. The largest population of species inhabit the northern slopes of Alborz Mountains


. Brown bear ( Ursus arctos ) population density has not been determined so far in the Eastern Black Sea Mountains, Türkiye, where the most fatal attacks are experienced in the country. Therefore, in

Autumn food habits of the brown bear Ursus arctos in the Golestan National Park: a pilot study in Iran

Food consumed by brown bears in the Golestan National Park in Iran was analyzed during autumn 2011, with the most important food items being hawthorn fruit, cherry plum fruit and chestnut-leaved oak hard mast.

Seasonal human-brown bear conflicts in northern Iran: implications for conservation

AbstractWe documented a number of brown bear Ursus arctos kills in rail and road accidents, for property protection and for control of bear-inflicted damage. The data were collected by interviewing

A preliminary baseline status of the Syrian Brown Bear Ursus arctos syriacus (Mammalia: Carnivora: Ursidae) in Golestanak, Northern Iran

Baseline information is lacking for the Syrian Brown Bear across the sub-species range, making it difficult to assess at any level.  In the present investigation, our goal was to illustrate the

Identifying priority core habitats and corridors for effective conservation of brown bears in Iran

This work applied species distribution modeling to predict habitat suitability and connectivity modeling to identify population core areas and corridors in Iran, and found low overlap between corridors, and core habitats with protected areas, suggesting that the existing protected area network may not be adequate.

Habitat suitability and connectivity for the brown bear (Ursus arctos) along the Iran-Iraq border

Habitat loss leads to habitat fragmentation. Habitat connectivity, however, could mitigate effects of habitat fragmentation on wildlife populations. This study was carried out to assess habitat



Appraising status of the Yellowstone grizzly bear population by counting females with cubs-of-the-year

The methodology of counts of distinct females with cubs-of-the-year as a recovery parameter in several grizzly bear ecosystems is described and its potential for continued use in the Yellowstone ecosystem is assessed.

Brown Bear Population Characteristics at McNeil River, Alaska

Observations of recognizable brown bears (Ursus arctos) at McNeil River State Game Sanctuary (MRSGS) during 1963-91 provided long-term data on population size, sex and age composition, reproductive

On the distribution and status of the Brown Bear, Ursus arctos, and the Asiatic Black Bear, U. thibetanus, in Iran

The Brown Bear can be found in large parts of the Elburz and the Zagros mountain ranges but reaches remarkable densities only in the decidous forests on the northern slopes of theElburz mountains.

The diet of grizzly bears in the Flathead River drainage of southeastern British Columbia

The hypothesis that a favourable food base in the Flathead is partially responsible for the high density of bears found there is supported by the analysis of 1100 feces or scats.


Viability analysis of well-selected focal species can complement ecosystem-level conservation planning by revealing thresholds in habitat area and landscape connectivity. Mammalian carnivores are
