TL;DR: It is suggested that camera trapping may be a robust complement to dung counts when monitoring ungulate communities, particularly when similarities between dung pellets from sympatric deer species make unambiguous assignment difficult.

Estimating population size using single-nucleotide polymorphism-based pedigree data.
TL;DR: A new census method based on pedigree reconstruction recently developed by Creel and Rosenblatt (2013) is tested, which genotyped fecal samples from two Swedish brown bear populations for pedigree reconstruction and fell within the 95% CI of the official estimates.

Small shrubs with large importance? Smaller deer may increase the moose-forestry conflict through feeding competition over Vaccinium shrubs in the field layer
Robert Spitzer,Eric Coissac,Annika M. Felton,Christian Fohringer,Laura Juvany,Marietjie Landman,Navinder J. Singh,Pierre Taberlet,Fredrik Widemo,Joris P. G. M. Cromsigt,Joris P. G. M. Cromsigt,Joris P. G. M. Cromsigt +11 more
TL;DR: It is found that in areas of high deer density, moose diets consistently contained less Vaccinium and higher proportions of pine over three spring periods, suggesting that managing key food items like vaccine and the populations of smaller deer may play an important role in controlling browsing impacts of moose on pine.

TL;DR: In this article , nutritional geometry revealed that moose mixed Scots pine Pinus sylvestris and Vaccinium spp. as nutritionally complementary foods to reach a nutritional target resembling Salix spp twigs.
