An Analysis of Government Actions for the Protection and Recovery of Forest-dwelling Woodland Caribou (Rangifer tarandus caribou) in Ontario, Canada

Rangifer, 2010
The Government of Ontario has legal responsibilities to protect and recover the province’s population of forest-dwelling woodland caribou, which is classified as a threatened species.

Status of woodland caribou in Ontario: 1996

Rangifer, 1998
Over 20 000 woodland caribou were reported in Ontario during 1966, the highest figure ever published. Photographic counts of the Pen Islands herd, bordering Manitoba, have shown constant increases from 2300 in 1979 to 10 800 in 1994. Elsewhere in Ontario, estimates have been declining, from 13 000 in 1965 to 11 000 in 1989 to under 10 000 in 1996, a ...

Potential Spectral Tuning of the Tapetum Lucidum in a Broadly Distributed Ungulate

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The tapetum lucidum, a biological reflector system found in the eyes of many vertebrate species, enhances visual sensitivity in low light conditions by reflecting light back through the retina. The structure of the ungulate tapetum fibrosum is unique, and its reflectance varies temporally in reindeer (Rangifer tarandus).

A Middle and Late Devensian sequence from the northern part of Kents Cavern (Devon, UK)

Journal of Quaternary Science, EarlyView.
Abstract 1920s/30s excavation of a Middle Devensian sequence in the northern part of Kents Cavern recovered important Late Middle and Early Upper Palaeolithic archaeological material, including Britain's oldest known Homo sapiens remains. Questions remain about this material, including how it came to be in the cave.

Forest fires, woodland caribou and land use policies in northwestern Ontario (Rangifer tarandus) [PDF]

, 2004
Woodland caribou (Rangifer tarandus caribou) are a threatened species in Ontario\u27s boreal forest. Caribou require habitat that supports appropriate forage, including large areas of lichen rich forests.

Lessons from integrating behaviour and resource selection: activity-specific responses of African wild dogs to roads [PDF]

, 2015
Understanding how anthropogenic features affect species' abilities to move within landscapes is essential to conservation planning and requires accurate assessment of resource selection for movement by focal species.

Vulnerable caribou and moose populations display varying responses to mountain pine beetle outbreaks and management

The Journal of Wildlife Management, EarlyView.
Mountain pine beetle outbreaks and associated management alter habitat selection by large ungulates. Using GPS collar data, we found that caribou responses to beetle‐affected, timber‐harvested, and burned areas varied across designatable units and depending on the amount of disturbance present within home ranges, while moose responses were sex‐specific.

Effects of boreal ground layer shrubs and bryophytes on the diversity, biomass and composition of lichen communities across contrasting ecosystems

Oikos, EarlyView.
There has been much recent interest in understanding how abiotic factors such as light, nutrients, and soil moisture affect the composition and biomass of lichen communities. Meanwhile, whether and how ground layer vegetation such as bryophytes and shrubs also influence lichen communities have received much less attention, particularly regarding how ...

The role of predation in the decline and extirpation of woodland caribou [PDF]

, 2020
To select appropriate recovery strategies for endangered populations, we must understand the dynamics of small populations and distinguish between the possible causes that drive such populations to low numbers. It has been suggested that the pattern of population decline may be inversely density-dependent with population growth rates decreasing as ...

Bridging the gap between science, policy and stakeholders: Towards sustainable wolf–livestock coexistence in human‐dominated landscapes

People and Nature, EarlyView.
Abstract While the return of wolves (Canis lupus) to many European countries is a conservation milestone, the negative impacts are unevenly distributed across society, placing high pressure on livestock grazing systems. For this perspective, scientists from diverse disciplines and geographical backgrounds reflect on the state of livestock–wolf ...
