Citizen scientists reveal: marine litter pollutes Arctic beaches and affects wild life [PDF]

, 2017
Recent data indicate accumulation areas of marine litter in Arctic waters and significant increases over time. Beaches on remote Arctic islands may be sinks for marine litter and reflect pollution levels of the surrounding waters particularly well.

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 ...

Snowmelt progression drives habitat selection and vegetation disturbance by an Arctic avian herbivore

Ecosphere, Volume 14, Issue 12, December 2023., 2023
Abstract Arctic tundra vegetation is affected by rapid climatic change and fluctuating herbivore population sizes. Broad‐billed geese, after their arrival in spring, feed intensively on belowground rhizomes, thereby disturbing soil, mosses, and vascular plant vegetation. Understanding of how springtime snowmelt patterns drive goose behavior is thus key

Seasonal and Interannual Dietary Variation During Winter in Female Svalbard Reindeer (Rangifer Tarandus Platyrhynchus) [PDF]

Arctic, Antarctic, and Alpine Research, 2009
Abstract We investigated dietary variation during three winters in female Svalbard reindeer (Rangifer tarandus platyrhynchus) on the basis of rumen samples from animals culled in early and late winter during 2000–2002. The winter diet was compared to a late summer diet on the basis of samples from 1999, with variations in dietary composition in early ...

Seasonal changes in the cecal microflora of the high-arctic Svalbard reindeer (Rangifer tarandus platyrhynchus). [PDF]

Appl Environ Microbiol, 1987
The dominant cecal bacteria in the high-arctic Svalbard reindeer were characterized, their population densities were estimated, and cecal pH was determined in summer, when food quality and availability is good, and in winter, when it is very poor. In summer the total culturable viable bacterial population was (8.9 +/- 5.3) X 10(8) cells ml-1, whereas ...

Long‐term herbivore removal experiments reveal how geese and reindeer shape vegetation and ecosystem CO2‐fluxes in high‐Arctic tundra

Journal of Ecology, Volume 111, Issue 12, Page 2627-2642, December 2023., 2023
By using two independent, long‐term herbivore removal experiments in high‐Arctic Svalbard, the authors show that controls on vegetation and ecosystem processes exerted by geese in their habitat (wet tundra) are larger than those exerted by reindeer in their habitat (moist‐to‐dry tundra).

High seasonal overlap in habitat suitability in a non-migratory High Arctic ungulate

Global Ecology and Conservation, 2023
Understanding drivers of space use and habitat selection is essential for management and conservation, especially under rapid environmental change. Here, we develop summer and winter habitat suitability models for the endemic wild Svalbard reindeer ...

Keeping cool in the warming Arctic: thermoregulatory behaviour by Svalbard reindeer (Rangifer tarandus platyrhynchus) [PDF]

Canadian Journal of Zoology, 2019
In animals with long generation times, evolution of physiological and morphological traits may not be fast enough to keep up with rapid climate warming, but thermoregulatory behaviour can possibly serve as an important buffer mitigating warming effects.

Clinical chemistry of farmed red deer (Cervus elaphus) yearling hinds reared on grass or papillonaceouspasture paddocks in Hungary. [PDF]

, 2013
. Yearling red deer (Cervus elaphus) hinds of identical initial body weight were reared on a monocotyledonous grass (group 1) or on a papillonaceous plant pasture (group 2) for 212 days.
