Ancient DNA reveals prehistoric gene-flow from Siberia in the complex human population history of North East Europe.

2013

North East Europe harbors a high diversity of cultures and languages, suggesting a complex genetic history. Archaeological, anthropological, and genetic research has revealed a series of influences from Western and Eastern Eurasia in the past. While genetic data from modern-day populations is commonly used to make inferences about their origins and past migrations, ancient DNA provides a powerful test of such hypotheses by giving a snapshot of the past genetic diversity. In order to better understand the dynamics that have shaped the gene pool of North East Europeans, we generated and analyzed 34 mitochondrial genotypes from the skeletal remains of three archaeological sites in northwest Ru…

Holocene interaction of maritime and continental climate in Central Europe: New speleothem evidence from Central Germany

2019

Central European climate is strongly influenced by North Atlantic (Westerlies) and Siberian High circulation patterns, which govern precipitation and temperature dynamics and induce heterogeneous climatic conditions, with distinct boundaries between climate zones. These climate boundaries are not stationary and shift geographically, depending on long-term atmospheric conditions. So far, little is known about past shifts of these climate boundaries and the local to regional environmental response prior to the instrumental era.\ud \ud High resolution multi-proxy data (stable oxygen and carbon isotope ratios, S/Ca and Sr/Ca) from two Holocene stalagmites from Bleßberg Cave (Thuringia) are used…

Coprology of Panthera tigris altaica and Felis bengalensis euptilurus from the Russian Far East

2007

Fecal samples from the Siberian tiger (Panthera tigris altaica) and the Amur cat (Felis bengalensis euptilurus) from Far Eastern Russia, were examined for parasites. A natural sedimentation methodology was used and a complete examination of all the sediment was performed. This fecal investigation allowed us to isolate and identify several developmental stages of gastrointestinal, hepatic, and respiratory parasites. Five parasites were found from P. t. altaica: 11 trematodes (Platynosomum fastosum) and 4 nematodes (Strongyloides sp., Ancylostomatidae, Toxascaris leonina, and Toxocara cati). Five parasites were found from F. b. euptilurus: 1 cestode (Diplopylidium sp.) and 4 nematodes (Trichu…

Heat shock protein Hsp70 expression and DNA damage in Baikalian sponges exposed to model pollutants and wastewater from Baikalsk Pulp and Paper Plant

2002

Abstract Lake Baikal, a unique habitat for a great number of endemic species, is the largest freshwater reservoir in the world which is still largely unaffected by anthropogenic pollution, except for some shore regions with industrial activity. The expressions of a biomarker of exposure (heat shock protein Hsp70) and a biomarker of effect (DNA single-strand breaks) were measured for the first time in endemic Baikalian sponge species (Baikalospongia intermedia, Lubomirskia fusifera, and Lubomirskia abietina). Tissue cubes of B. intermedia and dissociated cells of L. fusifera and L. abietina reacted to temperature stress (10–16 °C above ambient temperature) with a time-dependent increase in e…

Application de la photogrammétrie à la documentation de l’art rupestre, des chantiers de fouilles et du bâti

2017

During his archaeological missions the Museum of Prehistoric Anthropology tested the 3D modelling of several typesof objects. His team chose the ‘Structure-from-Motion’ (SfM) method which works according the basic principle of stereoscopicphotogrammetry, namely that 3D structure can be resolved from two or more overlapping, offset images. Most of other methodscapable of surveying, at high resolution, often complex objects and landforms are very expensive and have a difficult portability.Using only a consumer-grade digital camera and a scale on the ground, the user moves through the environment, acquiringphotographs of the area of interest from as many locations and perspectives as possible.…

Relationships between economic profitability and habitat quality of Siberian jay in uneven-aged Norway spruce forest

2012

Abstract In the southern and central parts of Finland, Siberian jay (Perisoreus infaustus) lives in large non-fragmented spruce-dominated forests. Due to the reduction of such forests, Siberian jay has disappeared from the southern parts of Finland. This study analyzed continuous-cover uneven-aged forest management as a way to maintain Siberian jay habitats simultaneously with timber production. Continuous cover management is able to provide the necessary spatial and temporal continuity of forest features important to the viability of Siberian jay populations. The study analyzed the relationship between habitat quality of Siberian jay and profitability of uneven-aged management of Norway sp…

Quo vadis SANEPID? A cross-country analysis of public health reforms in 10 post-Soviet states

2010

Abstract Background The public health systems of the post-Soviet states have evolved from the san-epid system, which dominated public health practice throughout the former Soviet Union. Since independence, reforms have taken different directions. This article provides a cross-country comparison of public health reform processes and contents in 10 post-Soviet states. Methods The study is descriptive and comparative, based on a literature review of the major health databases, the Health Systems in Transition (HiT) volumes and grey literature. Search terms included terms on public health, the san-epid services and organizational reforms in one or several post-Soviet states. Results Public heal…

Zbigniew Jacorzyński

2017

Pułkownik Zbigniew Jacorzyński to postać wybitnie zasłużona dla polskiego pożarnictwa. Urodził się 8 sierpnia 1921 roku w Cieszynie. Był synem oficera Wojska Polskiego. W młodości udzielał się w polskim harcerstwie. W 1937 roku stanął do poboru i dostał przydział do broni pancernej, głównie z powodu fascynacji motoryzacją. W 1939 roku ukończył liceum o profilu matematyczno-fizycznym, po czym odbył obowiązkową sześciotygodniową służbę w Junackich Hufcach Pracy w Równym, na granicy Polesia i Wołynia. W dniu 17 września 1939 roku, kiedy Sowieci przekroczyli polską granicę, cały hufiec został zmobilizowany i skierowany na odsiecz Brześcia nad Bugiem, zajętego wówczas przez Niemców. Po drodze żo…
