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 ...

Ecological Solutions and Evidence, Volume 7, Issue 4, October–December 2026.Despite growing efforts to bring Indigenous and Western knowledge together in caribou research, inconsistent reporting of collaboration, ethics, knowledge sharing and Indigenous governance over data continue to limit transparency, accountability and true co‐production of knowledge.

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.

Humans are not unique: difficult birth is common in placental mammals
Biological Reviews, Volume 101, Issue 5, Page 2214-2239, October 2026.ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Improving predictions of insect harassment for barren‐ground caribou in the Arctic
Ecological Applications, Volume 36, Issue 7, October 2026.Abstract Many populations of barren‐ground caribou (Rangifer tarandus) have declined or are declining, which is concerning given their ecological role in Arctic ecosystems and their societal role in northern communities. Insect harassment is an important driver of the behavior, energetics, and demographic rates of caribou, and yet, due to challenges in

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.

Contrasting African elephant movescapes across xeric and mesic savannas
Ecological Applications, Volume 36, Issue 7, October 2026.Abstract Expanding human activities increasingly influence animal movement. Yet, conservation interventions often overlook intraspecific variation in how movement is structured across populations inhabiting distinct ecosystems. For wide‐ranging generalists such as African savanna elephants (Loxodonta africana), understanding how responses to resource ...

Application of close‐kin mark–recapture to an American black bear population using harvest samples
Ecological Applications, Volume 36, Issue 7, October 2026.Abstract Close‐kin mark–recapture (CKMR) offers a promising alternative to traditional mark–recapture methods for estimating wildlife population parameters. CKMR estimates demographic parameters by identifying genetic relationships between individuals, effectively “recapturing” parental genotypes through their offspring's genetic profiles.
