The chromosomes of reindeer (Rangifer tarandus)
Rangifer, 1986 The karyotypes of Rangifer t. tarandus L . and Rangifer t. fennicus Lonnb. have been established. The chromosomes have been stained by several methodes (G-, C-, Qand R-banding, NOR-staining). The chromosome number is 70, N F is 74. The autosomes consist of 33 acrocentric pairs and one submetacentric pair (no. 34).

Seasonal Habitat Selection by a Threatened Ungulate in an Industrializing Boreal Landscape
Animal Conservation, EarlyView.Understanding habitat selection by Threatened wood bison in landscapes characterized by anthropogenic disturbance is important for conservation planning. During summer and winter, bison selected for linear (e.g., roads, seismic lines, pipelines) and polygonal (e.g., well sites) disturbances, unless there were high densities of linear features.

Reindeer (Rangifer tarandus) and climate change: Importance of winter forage
, 2002 As a consequence of increasing greenhouse gas concentrations, climate change is predicted to be particularly pronounced, although regionally variable, in the vast arctic, sub-arctic and alpine tundra areas of the northern hemisphere.

Modeling Regional Dynamics of Human-Rangifer Systems: a Framework for Comparative Analysis
Ecology and Society, 2013 Theoretical models of interaction between wild and domestic reindeer (Rangifer tarandus; caribou in North America) can help explain observed social-ecological dynamics of arctic hunting and husbandry systems.

Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe
Archaeometry, EarlyView.ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).

Quantitative differentiation of types of feeding craters of Rangifer tarandus fennicus
, 1992 During winter 1983-1984 in the Kainuu region of eastern Finland, based on 1363 api profiles, the Värriö Snow Index (VSI) modelled 3 different types of feeding craters dug by Rangifer tarandus fennicus. When mean log VSI of control sites = 1.4 ca.

Impacts of human activity on reindeer and caribou: The matter
Rangifer, 2007 The impacts of human activity and infrastructure development on reindeer and caribou (Rangifer tarandus) have been studied for decades and have resulted in numerous debates among scientists, developers and indigenous people affected.

Boreas, EarlyView.Our knowledge of the Early Upper Palaeolithic occupation in northern central Europe is very limited, and recent research at the open‐air site of Friedrichsdorf‐Seulberg in Hesse, Germany, provides important new information on the Aurignacian. The site is rather small (26.5 m2) and spatial analysis identified a central hearth with two associated ...
