A century of conservation: The ongoing recovery of Svalbard reindeer [PDF]

open access: yesThe Journal of Wildlife Management, 2019
ABSTRACTSeveral caribou and reindeer (Rangifer tarandus) populations have experienced recent population declines, often attributed to anthropogenic stressors such as harvesting, landscape fragmentation, and climate change. Svalbard reindeer (R. t.

Arctic Greening Drives Changes in the Diet and Gut Microbiome of a Large Herbivore With Consequences for Body Mass [PDF]

open access: yesEcology and Evolution
Rapid climate warming is ‘greening’ the tundra, reflecting a higher plant biomass, particularly of deciduous shrubs and grasses. However, the consequences of these changes for herbivore nutrition are unclear.

Contrasting genomic consequences of anthropogenic reintroduction and natural recolonization in high‐arctic wild reindeer [PDF]

open access: yesEvolutionary Applications, 2023
Anthropogenic reintroduction can supplement natural recolonization in reestablishing a species' distribution and abundance. However, both reintroductions and recolonizations can give rise to founder effects that reduce genetic diversity and increase ...

Rumen microbial diversity in Svalbard reindeer, with particular emphasis on methanogenic archaea [PDF]

open access: yesFEMS Microbiology Ecology, 2009
Ruminal methanogens, bacteria and ciliate protozoa of Svalbard reindeer grazing natural pastures in October (late fall) and April (late winter) were investigated using molecular-based approaches. The appetite of the Svalbard reindeer peaks in August (summer) and is at its lowest in March (winter). Microbial numbers, quantified by real-time PCR, did not

The frequency of antlerless females among Svalbard reindeer

open access: yesRangifer, 1998
The distribution of females with no, one and two antlers was recorded during July 1994 in Svalbard reindeer, Rangifer tarandus platyrhynchus, and compared wirh 1974 data from Reimers (1993) and Larsen (1977).

Ancient reindeer mitogenomes reveal island-hopping colonisation of the Arctic archipelagos [PDF]

open access: yesScientific Reports
Climate warming at the end of the last glacial period had profound effects on the distribution of cold-adapted species. As their range shifted towards northern latitudes, they were able to colonise previously glaciated areas, including remote Arctic ...

Extreme events, trophic chain reactions, and shifts in phenotypic selection [PDF]

open access: yesScientific Reports, 2023
Demographic consequences of rapid environmental change and extreme climatic events (ECEs) can cascade across trophic levels with evolutionary implications that have rarely been explored.
