The order grebes (Podicipediformes) is an archaic group of birds, morphologically and ecologically well adapted to the aquatic life style, including breeding in floating nests in the littoral zone of water bodies. Four grebe species are breeding in fishponds in the Czech republic. Annually during the breeding season, these birds have to overcome many problems to successfully breed. In the incubation period, the most important mission for parents is to protect the eggs from predation. and Jan Sychra.
Successful rearing of a grebe (Podicipediformes) brood depends on several environ - mental factors, such as climatic conditions and food supply at the breeding site. In connection with their insufficient thermoregulation in the first days of their life grebe chicks are brooded, warmed and fed, under the wings on the back of their pa - rents. Although grebes are very adaptable birds, fishpond degradation is currently inducing a decrease of these waterbirds. and Jan Sychra.
Českou verzi knihy vyhlásil časopis „Dějiny a Současnost“ v roce 2013 jako nejlepší českojazyčnou historickou práci roku. Využití konceptů moderních západoevropských sociálních a kulturních dějin na české matérii se nakonec ukázalo i jako velmi atraktivní pro mezinárodní vědeckou obec, o čemž svědčí v dubnu 2016 publikovaný překlad rozšířeného a dopracovaného textu anglo-americkým nakladatelským domem Berghahn Books., The book by the historian Rudolf Kučera, a permanent researcher at the Masaryk Institute and Archives of the Czech Academy of Sciences, contributes to our understanding of the working-class life in central Europe during World War I. Far from the battlefront, hundreds of thousands of workers toiled in Bohemian factories over the course of World War I, and their lives were inescapably shaped by the conflict. In particular, they faced new and dramatic forms of material hardship that strained social ties and placed in sharp relief the most mundane aspects of daily life, such as when, what, and with whom to eat. This study reconstructs the experience of the Bohemian working class during the Great War through explorations of four basic spheres - food, labor, gender, and protest - that comprise a fascinating case study in early twentieth-century social history., and Rudolf Kučera.
