Arctic ungulates at the northern edge of terrestrial life

open access: yesRangifer, 1996
The two ungulate species that occur in the High Arctic, Rangifer tarandus and Ovibos moschatus, exhibit considerable adaptive plasticity in response to habitat variability throughout their circumpolar distribution. R.

From the brink of extinction to regulation: northern Europe's white‐tailed eagles now face density dependence and climate constraints after rapid population growth

open access: yesOikos, EarlyView.
Population growth reflects the combined influence of regulation and density‐independent factors operating through demographic processes. Under exceptional circumstances (e.g. populations recovering from near‐extinction), growth may initially be weakly regulated but typically slows as negative density dependence (NDD) sets in.

Ultrastructure of Besnoitia cysts from reindeer (Rangifer tarandus tarandus L)

open access: yesRangifer, 1990
The ultrastructure pf Besnoitia cysts in reindeer is described. The observations made on Besnoitia cysts and merozoites indicate a form distinct enough to be placed in a new species - Besnoitia tarandi.

Investigating conservation performance payments alongside human–wildlife conflicts: The Swedish lynx and wolverine protection policies

open access: yesPeople and Nature, EarlyView.
Abstract Conservation performance payments are becoming an increasingly popular instrument to tackle human–wildlife conflicts. In Sweden, Sámi communities practicing reindeer husbandry receive performance payments as compensation for reindeer losses caused by lynxes and wolverines.

Shifting the paradigm: An Indigenous knowledge‐based stewardship plan to replenish boreal caribou in Athabasca Chipewyan and Mikisew Cree First Nations' homelands

open access: yesPeople and Nature, EarlyView.
Abstract Indigenous Peoples in northern Alberta, including Dené and Cree of the Athabasca Chipewyan and Mikisew Cree First Nations (ACFN and MCFN), have been using Indigenous laws and stewardship principles to care for their homelands for thousands of years. Since ACFN and MCFN signed Treaty 8 with Canada in 1899, Alberta's land management policies and

Influence of ground substrate on establishment of reindeer lichen after artificial dispersal [PDF]

open access: yes, 2007
Methods to improve the recovery of reindeer lichen after soil disturbance or overgrazing are being sought for areas where reindeer are herded. The effects of four substrates – mineral soil, moss, twigs and pine bark – on the establishment of lichen ...

Lacking data? No worries! How synthetic images can alleviate image scarcity in wildlife surveys: A case study with muskox (Ovibos moschatus)

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study investigates the integration of synthetic imagery, created with diffusion‐based models, to supplement limited training data and improve muskox (Ovibos moschatus) detection in zero‐shot (ZS) and few‐shot (FS) settings. ZS models detected more than 80% of muskoxen in real images, confirming the potential of synthetic data as a substitute for ...

Growth rates and morphological measurements of Porcupine caribou calves

open access: yesRangifer, 1989
Body weights, leg lengths, and surface area were monitored for bottle-raised barren-ground caribou calves (Rangifer tarandus granti) from the Porcupine herd up to 1 year of age.

Ungulate substrate use in fauna passages

open access: yesWildlife Biology, EarlyView.
Fauna passages are increasingly constructed at major roads and railways to mitigate the negative effects of infrastructure and traffic on wildlife. The function of such passages depends on design, including the construction materials, soil, and vegetation.

Elaphostrongylus spp. from Scandinavian cervidae - a scanning electron microscope study (SEM)

open access: yesRangifer, 1990
Nematodes of the genus Elaphostrongylus collected from moose (Alces alces L.), reindeer (Rangifer tarandus tarandus L.), and red deer (Cervus elaphus L.), respectively, were studied by means of scanning electron microscopy.
