“…Although other studies have identified rocky sites as important for lynx, e.g. for den site selection (Boutros et al 2007), increased hunting success (Krofel et al 2007) and scent marking (Vogt et al 2014), our study is to the best of our knowledge the first to empirically stress the significance of rock formations as resting habitats for lynx. In general, Table 1.…”

“…Contrary to other carnivore‐denning studies (Boutros et al ., ; May et al ., ), lynx in the northern study site preferentially selected den sites at lower, rather than higher, elevations. Other authors (Petram, Knauer & Kaczensky, ) have suggested dens at higher elevations reduce encounters with humans.…”

“…The most consistent feature that lynx selected for across Norway was den sites that were associated with more rugged terrain than available, similar to denning lynx elsewhere in Europe (Boutros et al ., ; Krofel, Skrbinšek & Kos, ). Rugged terrain potentially reduces disturbance and mortality risk by limiting human access (Magoun & Copeland, ; Ross et al ., ) and likely shelters lynx kittens from the elements (Boutros et al ., ). Considering the retrospective nature of this study, microstructural features of each natal den site were not investigated, but rocky outcrops that offer shelter and dense vegetation at the den also likely influence den selection across Norway.…”

“…Although more research is required on early kitten mortality, natural causes such as starvation and disease are thought to play a role, and in Norway intra‐guild predation is not considered an important factor (Andrén et al ., ). Only two detailed studies, undertaken in Poland (Schmidt, ) and Switzerland (Boutros et al ., ), have described Eurasian lynx denning behaviours, with both studies reporting that secure and well‐camouflaged den sites are a prerequisite for kitten survival. No published data exist from northern Europe, where climatic conditions are especially challenging and where there are important differences in lynx management practices that may influence patterns of habitat selection.…”

Eurasian lynx natal den site and maternal home‐range selection in multi‐use landscapes of Norway

et al. 2015

In carnivores, securing suitable den sites with associated early maternal home ranges is important for successful reproduction, and understanding natal den site selection is essential to ensure that these habitats are protected from human disturbance. This study investigated Eurasian lynx Lynx lynx natal den site selection across multiple use landscapes in Norway and explores whether the selection of early maternal home ranges across southern Norway involved a trade-off of security for access to their preferred prey species, roe deer Capreolus capreolus. The characteristics of natal dens and home ranges from 33 reproductive events were quantified across south-eastern and northern Norway. Natal dens were located in terrain further from the most accessible and disturbed areas (public roads) and in terrain more rugged than generally available. Early maternal home ranges were characterized by low human and low road density in rugged terrain and a selection for areas associated with higher or lower roe deer densities was not important in our analysis. Humans are the dominant cause of lynx mortality throughout Norway and our findings suggest that female lynx primarily chose areas that limited their interaction with people during the denning period.

Analysis of global positioning system (GPS) location clusters (GLCs) is becoming increasingly popular in studies of carnivore ecology. While promising, this application of GPS technology is still poorly developed for most species. We applied this method to study predation and maternal behavior of the Eurasian lynx (Lynx lynx) in Dinaric Mountains. Low population densities, rugged terrain, dense vegetation, and administrative borders make studies of this endangered population using traditional methods and a limited budget very challenging. We used geographic information system (GIS) and linear mixed effects models to understand the movement of lynx during the consumption process and denning period and estimate lynx kill rates. 99% of kills were found at GLCs longer than 30 h and with minimum two locations within 300 m. We confirmed 86% of potential kills and all potential dens that were searched for in the field. High success in predicting kill and den sites showed that Eurasian lynx is a suitable species for application of the GLC analysis methods. Comparison of field-confirmed kills with model predictions showed the possibility for remote estimation of approximate kill 2 rates in Eurasian lynx. Movements of lynx were primarily affected by daytime period, time since the last kill/den translocation, lynx category and their interactions. Based on the empirical data we programmed simulations of lynx movements and elaborated recommendations for more efficient field procedures and study designs (GPS schedules) for future studies. We believe that our findings and approach will also benefit studies of other species with similar behavior.
