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.

Forest and fire drive moose (deníe) detections near their northern range limit

open access: yesWildlife Biology, EarlyView.
One way to understand species range shifts in response to anthropogenic climate change is to study populations living at the limit of climate and resource suitability. Moose Alces alces (deníe in Dënesųłıné) generally require forest–wetland landscape complexes but are increasingly seen across the forest–tundra transition at their northern range limit ...

Quantitative differentiation of types of feeding craters of Rangifer tarandus fennicus [PDF]

open access: yes, 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.

Reproductive success under constraints: Does increased maternal activity during lactation offset poor habitat and individual quality in an income breeder?

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐induced environmental modifications may alter forage access and, hence, how animals manage energy trade‐offs during critical periods. Reproduction, especially lactation, is the most energetically costly process for female mammals.

Effects of medetomidine and atipamezole on serum glucose and cortisol levels in captive reindeer (Rangifer tarandus tarandus) [PDF]

open access: yes, 1999
Serum concentrations of glucose and Cortisol were measured in five adult captive reindeer (Rangifer tarandus tarandus) at 24 h and 10 min before, and at 0.5, 1,2,4, 8, 12 and 24 h after, treatment with 60 p.g/kg of medetomidine i.v.

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.

Playing with fire: Wolf response to active wildfires, fire fronts and smoke

open access: yesJournal of Animal Ecology, EarlyView.
This study is one of the first, to our knowledge, to explicitly examine fine‐scale behavioural responses of a large carnivore to actively burning wildfires, fire fronts and smoke. The study found that wolves balanced the potential risks and benefits associated with wildfires, with implications for predator–prey dynamics in fire‐prone regions.
