Distribution and estimation of abundance of hazel grouse (Bonasa bonasia) in the Jeseníky Mts. and Rychlebské hory Mts
Koubek, Petr ; Novotný, L. ; Červený, Jaroslav
Hazel grouse (Bonasa bonasia) is the most abundant living galliform bird in the Jeseníky Mts. Since 1984, changes of its abundance, data on biotop preference, amount of chickens and food composition have been followed.The study area is composed of the eastern slopes of Pradid Mt. up to Vrbno pod Pradidem (about 3000 ha). Data about its distribution and abundance in the entire area of Hrubý and Nízký Jeseník Mts. and also Rychlebské hory Mts. (districts Šumperk, Bruntál, Jeseník) were gathered by questionaires in individual hunting grounds where the occurrence of hazel grouse is regular but also in hunting grounds where the occurrence may be assumed.

Current knowledge on distribution, population dynamics and feeding ecology of some mustelids in the Czech Republic
Koubek, Petr ; Červený, Jaroslav ; Bufka, L.
Although mustelids comprise the most abundant group of predators in the Czech Republic, they are one of the least studied groups of our mammals. Since there is an absence of data necessary for their protection or the level of management, data about for ecology and abundance of oine marten (Martes martes), stone marten (M. foina), western polecat (Mustela putorius), steppe polecat (M. eversmannii), weasel (M. nivalis) and stoat (M. erminea) were synthesized.
