Integrating cryobanks into conservation frameworks: The case of boreal caribou in Ontario

Conservation Science and Practice, EarlyView.
Conservation cryobanks are a powerful but underutilized complement to conventional recovery strategies such as habitat protection and population monitoring. Here, we present a transferable, stepwise framework for integrating cryobanking into formal species recovery plans, including guidance on population prioritization, partner engagement, and the ...

Reindeer (Rangifer tarandus) and climate change: Importance of winter forage [PDF]

, 2002
As a consequence of increasing greenhouse gas concentrations, climate change is predicted to be particularly pronounced, although regionally variable, in the vast arctic, sub-arctic and alpine tundra areas of the northern hemisphere.

Morphofunctional effects of captivity on the microanatomy of the talus bone in a wild ungulate (Sus scrofa)

Journal of Anatomy, EarlyView.
Our study explores the plastic changes induced by captivity on the microanatomy of the talus of wild boars, revealing denser bone with tighter trabecular networks but a lower relative maximum thickness of compact bone. These plastic adaptations can serve to detect early processes of domestication in the archaeological record.

The Long Arc of Forest Land Dispossession and Degradation—Firm and State Actions on Sámi Lands in the Wood‐Based Commodity Frontier in Northern Sweden, 1673–1955

Journal of Agrarian Change, EarlyView.
ABSTRACT This article presents a new way of obtaining deep explanations of environmental problems. We expose the production strategies, corporate strategies and state actions that have been taken by firms and state agencies to facilitate the geographical expansion of the wood‐based commodity frontier at the expense of reindeer pastoralists among the ...

A study of the impact of population bottlenecks on the genetics and morphology of reindeer (Rangifer tarandus tarandus) on the island of South Georgia [PDF]

, 2007
Numerous studies have shown that population bottlenecks result in loss of genetic diversity and as a consequence of this, it is commonly inferred that there is a loss of evolutionary potential.

The status of Rangifer tarandus caribou in Yukon, Canada

, 1998
This paper summarizes the population trends as well as research and management programs for woodland caribou {Rangifer tarandus caribou) in Yukon. Most herds are stable although not all are counted regularly and systematic monitoring of herds remains an ...

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Different methods of preparing rumen and caecum content from reindeer (Rangifer tarandus tarandus) for the analyses of minerals [PDF]

, 1982
Different methods were used for preparation of samples of rumen and caecum content from reindeer. The mineral contents of the samples were compared. Rumen and caecum samples from three reindeer were centrifuged at sampling and the fluid was stored frozen.

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
