Rethinking the basic conservation unit and associated protocol for augmentation of an "endangered" caribou population: An opinion

Rangifer, 2007
Use of the subspecies as the basic unit in the conservation of endangered caribou (Rangifer tarandus) would produce a “melting pot” end-product that would mask important genotypic, phenotypic, ecological, and behavioral variations found below the level ...

Improving predictions of insect harassment for barren‐ground caribou in the Arctic [PDF]

Ecol Appl
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

Calcium Isotopic Composition in Reindeer (Rangifer tarandus) Bones and Tooth Enamel: A Scalable Tool to Quantify Nursing Frequency in Past and Modern Populations? [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale Populations of North American caribou and Eurasian reindeer (Rangifer tarandus sspp.), essential for Arctic ecosystems and human communities, are experiencing unprecedented declines due to climate change and anthropogenic pressures. While understanding their historical resilience and demographic dynamics is critical for conservation,

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

Journal 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.

Behavioral and demographic effects of open‐pit mining on Central Mountain Caribou in British Columbia

Conservation Science and Practice
Although population management measures have been used to avoid continued extirpation of caribou (Rangifer tarandus caribou) in some areas of British Columbia (BC), protection and restoration of their range remain challenging.

Status of woodland caribou in Alberta

Rangifer, 1998
A recent review of woodland caribou {Rangifer tarandus caribou) status in Alberta estimated that there are between 3600 and 6700 caribou occupying 113 000 km2 of habitat.

Burned habitats facilitate predation and lead to long‐term reductions in prey success

Journal of Animal Ecology, EarlyView.
By evaluating the effects of burned habitats on the habitat selection and movement responses of cougars and mule deer, cougar kill sites, and mule deer reproduction, the authors find that increasingly large, severe burns are diminishing herbivore reproductive success, potentially due to advantages for predators created by burned landscapes.

Successful and unsuccessful attempts to resolve caribou management and timber harvesting issues in west central Alberta

Rangifer, 1996
Research studies of woodland caribou in west central Alberta began in 1979 in response to proposed timber harvesting on their winter ranges. Using results from initial studies, timber harvest guidelines were developed. A recent review of these guidelines,

125 years of exploration and research at Gough's Cave (Somerset, UK) 125 ans d'exploration et de recherches à Gough's Cave (Somerset, Royaume‐Uni)

Journal of the Royal Anthropological Institute, EarlyView.
Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...

Gough's Cave and biomolecular archaeology: a story of evolving interpretation Archéologie biomoléculaire à la grotte de Gough's Cave : une interprétation en constante évolution

Journal of the Royal Anthropological Institute, EarlyView.
Gough's Cave is a key archaeological site that has been at heart of British archaeology for the past century. Professor Chris Stringer, whom this special issue honours, has been a key figure in excavations and research projects at the site for many decades.
