Neonate mortality in fallow deer (Dama dama) in relation to bed-site selection and habitat use
The level of neonate mortality in a free ranging fallow deer (Dama dama) population at the Koberg estate in south western Sweden was investigated using radio-tracking techniques. During this study a total of 36 fawns (17 ?, 19 ?) were captured and marked with vhf or gps radio collars; 12 fawns in 2008 and 24 fawns in 2009. The neonate mortality calculated by the Kaplan-Meier method was 23.6 % and the mortality caused by predation was low, since only 1 of 8 non-surviving fawns died from predation by red fox (Vulpes vulpes). The spatial behavior of the fallow deer neonates were examined at two different levels i.e.

Hur styr gruppcertifikatägarnas strategier vilka skogsägare som blir del av FSC-cerfifikaten?
This study investigates the relationship strategies the group Forest Stewardship Council (FSC) certification holder has with the forest owners.
