- Abstract:
- ... Caucasian black grouse (Tetrao mlokosiewiczi) is on the ‘red’ list of species of high conservation concern as nearest threatened (NT) and also in level (I) of Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The black grouse distribution range in Iran is restricted to the Arasbaran region, Northwest of Iran, and the populations and range of this specialist b ...

- Abstract:
- ... Increasing forest cover has been the policy of various countries in recent decades. The Scottish government aims to increase national forest cover from 18% to 25% by 2050. Mid-altitude upland areas above farmland and below the natural tree line will be targeted for planting, which could impact black grouse Tetrao tetrix, a species of conservation concern which is most abundant in this zone. We use ...

- Abstract:
- ... Females may use condition-dependent sexual traits as reliable cues of male “quality” if the costs of the expression of such traits vary with male “quality”, and if there is positive genetic correlation between male traits and condition. However, there are multiple ways of measuring the changes in body condition which reflect physiological costs meaning that the multifaceted nature of the physiolog ...

- Abstract:
- ... We interrogate an 18-year-long dataset containing counts of displaying male black grouse Tetrao tetrix and incidental counts of females within an 800-km2 region of Perthshire, Scotland. We examine the trends in the population and investigate how different components of the population might act as signposts of different stages of overall population change. We found statistical evidence for a declin ...

Micro-habitat characteristics of breeding display Sites (Leks) of Caucasian Black Grouse (Tetrao mlokosiewiczi) were studied in the mountains of Arasbaran Region, East Azerbaijan, from October 2006 to June 2008. We quantified micro-habitat characteristics around active and inactive Caucasian black grouse lek sites and random points in the 3 areas (Biosphere reserve, Kalan protected area (one of co ...

We compared the genetic diversity in the last extant Dutch population with Dutch museum samples and three other black grouse populations (from England, Austria and Norway, respectively) representing isolated and continuous ...

Tourism and leisure activities have increased continuously all over the world during the past decades, exerting a growing pressure upon naturally fragile ecosystems, such as mountainous habitats. Recent studies have established that disturbance by outdoor winter sports (e.g. skiing, snowboarding and snowshoeing) is a source of stress for wildlife. This may in turn affect its abundance, but we s ...

While it has been shown that fragmentation and modern forestry practices such as clear-cutting affect the viability of grouse populations, little is known about effects of large-scale drainage. The drainage network in Finland has increased dramatically during the past decades. By 1988, 6 million ha of bog ecosystems had bee ...

- Abstract:
- ... The Caucasian black grouse (CBG) is classified as “data deficient” by the IUCN. Lack of information to guide conservation measures is mainly due to the bird’s elusive behaviour for much of the year and to its remote distribution at higher altitudes of the Caucasus Mountains. In order to fill some of the knowledge gaps, we mapped potential suitable habitat across the Turkish part of the Lesser Cauc ...

Weather affected habitat use by brood hens: on sunny days 18 broods were encountered in meadows, six in ravines, and three in pine forests; on wet days broods moved to the ridge tops (N = 9) and only one was observed in ...

Our analyses provide, for the first time, a robust estimate of the evolutionary history of these birds. These analyses are based on aligned sequences of 3,809 basepairs of five complete mitochondrial genes. Our classification does not require novel genera and generally r ...
