Transferrin variation and evolution of Alaskan reindeer and caribou, Rangifer tarandus L.

Rangifer, 1986
Polyacrylamide gel electrophoresis was used to analyse transferrin variation in wild caribou (Rangifer tarandus granti) and domestic reindeer (R.t. tarandus) from Alaska. Eighteen alleles were detected in caribou and ten alleles were detected in reindeer.

The “costly son” hypothesis: Sons exacerbate obstetrical dilemmas in humans and other mammals

The Anatomical Record, EarlyView.
Abstract Human childbirth has often been considered uniquely difficult among mammals, yet recent evidence suggests that obstructed labor and fetopelvic disproportion are widespread across placental mammals. Here, we propose the “costly son” hypothesis: because male offspring are typically larger at birth, they impose greater obstetric risk on mothers ...

A global meta‐analysis of non‐lethal mammal browsing control in forests

Biological Reviews, EarlyView.
ABSTRACT Increasing resource demand, desire to sequester atmospheric carbon, and conservation goals are driving a need for forests to be managed more effectively in the face of numerous challenges. One such challenge is damage perpetrated by browsing mammals, which can cause substantial financial and ecological impacts.

Reindeer meat – is it always tender, tasty and healthy?

Rangifer, 2007
Meat with high pH values, so called DFD (Dark, Firm, Dry meat, is a persistent quality defect foundmin all meat species. DFD shortens shelf life, especially for vacuum-packed meat and affects meat colour, tenderness and water-holding properties.

Increase in plant productivity in the tundra in Sweden is not related to increasing presence of warm‐adapted vascular plant species

Ecography, EarlyView.
Over the past decades, Arctic and alpine biomes have warmed faster than the global average. Substantial vegetation changes have been reported as a response to this warming, including increased productivity and the spread of warm‐adapted (thermophilic) species that are less resistant to grazing pressure into higher latitudes and altitudes.

Reindeer in the USSR: problems of protection and rational use

Rangifer, 2010
There are approximately 2.2 million domestic and 1 million wild reindeer in the USSR today. It is unlikely that the number of domestic reindeer will increase further but there is a tendency for further growth in several large populations of wild reindeer.

Geochronological reconstruction of the Lateglacial deglaciation in the Arve Valley (Northern French Alps)

Journal of Quaternary Science, EarlyView.
ABSTRACT The timing and spatial patterns of glaciers retreat in the Northern French Alps during the Lateglacial (19.0–11.7 ka) remain debated, reflecting discrepancies among available chronological data sets. The complex interactions between major glaciers, such as the Rhône and Arve glaciers to the north and the Isère glacier to the south, represent a
