Limiting factors in caribou population ecology
Rangifer, 1991 Caribou and wild reindeer populations fluctuate over time. On this fact there is general agreement. Factors responsible for population limitation and subsequent declines have been examined within the framework of animal population theory.

Using information theory to select spatial scales for species–habitat responses with camera traps
Ecological Applications, Volume 36, Issue 4, June 2026.Abstract Widespread anthropogenic landscape change, particularly from energy development, has fundamentally reshaped ecosystems, and understanding species responses remains a central ecological challenge. Remote camera traps are widely used to estimate mammal abundance and distribution, but inferring species–habitat relationships from these data is ...

Granulomas in the tongue of reindeer (Rangifer tarandus L)
, 1983 In 3 out of 33, 11 months old male reindeer which during around 3 months had been kept on comercial fodder, granulomas were found at autopsy, in the submucosa of the ventrolateral aspect of the tounge. In two of the granulomas were present worms of genus

Reindeer breathe less and save water in the cold
Rangifer, 1990 Simultaneous measurements of metabolic rate, respiratory minute volume, respiratory frequency, and oxygen extraction from the inspired air were obtained during treadmill exercise in Svalbard reindeer (Rangifer tarandus platyrhynchus) and Norwegian ...

Direct Interaction Between Roe Deer and Mountain Hare, a Case of Interference Encounter Competition?
Ecology and Evolution, Volume 16, Issue 6, June 2026.Here, we report on a case of direct interaction between a roe deer doe and a mountain hare recorded by a camera trap in Tydal Municipality, Norway, suggestive of direct interference competition. The roe deer doe is following and displacing the mountain hare for at least 2 min and 29 s, including a 19 s active phase.

Reindeer use of alpine summer habitats [PDF]
, 2006 Alpine areas in the Scandinavian mountain region are used for grazing by semi-domesticated reindeer (Rangifer tarandus tarandus) during the snow-free season. These areas are also used for outdoor recreation and tourism.

Comparative response of Rangifer tarandus and other northern ungulates to climatic variability
, 2002 To understand the factors influencing life history traits and population dynamics, attention is increasingly being given to the importance of environmental stochasticity.

Ecography, Volume 2026, Issue 6, June 2026.The spatial ecology of stalk‐and‐ambush predators like the Eurasian lynx Lynx lynx depends on prey availability and environmental features, yet the relative roles of these factors remain unclear at large spatial scales. In this study, we analysed lynx habitat use across central and southern Finland using snow‐track data from the Wildlife Triangle ...

Warming summers limit reindeer grazing, weakening herbivory pressure in the mountain tundra
Ecography, Volume 2026, Issue 6, June 2026.Climate change is predicted to alter species interactions by exposing ecosystems to increasingly frequent and intense warm spells. In the mountain tundra, grazing by large herbivores, particularly reindeer, can limit shrub expansion and preserve Arctic plant diversity.
