We studied the influence of surveyed area size on density estimates by means of camera-trapping in a low-density felid population (1-2 individuals/100 km(2) ). We applied non-spatial capture-recapture (CR) and spatial CR (SCR) models for Eurasian lynx during winter 2005/2006 in the northwestern Swiss Alps by sampling an area divided into 5 nested plots ranging from 65 to 760 km(2) . CR model density estimates (95% CI) for models M0 and Mh decreased from 2.61 (1.55-3.68) and 3.6 (1.62-5.57…

Spatial density estimates of Eurasian lynx (Lynx lynx) in the French Jura and Vosges Mountains
TLDR
This study focuses on the Eurasian lynx (Lynx lynx) in the French Jura and Vosges Mountains and provides the first density estimates, yet another example of the advantage of combining SCR methods and non-invasive sampling techniques to estimate density for elusive and wide-ranging species like large carnivores.
Spatial density estimates of Eurasian lynx (Lynx lynx) in the French Jura and Vosges Mountains
TLDR
The first density estimates of the Eurasian lynx (Lynx lynx) in the French Jura and Vosges mountains are provided, providing an example of the advantage of combining SCR methods and noninvasive sampling techniques to estimate density for elusive and wide‐ranging species.
Demography of a Eurasian lynx (Lynx lynx) population within a strictly protected area in Central Europe
TLDR
This first open population SCR study on lynx provides sex-specific demographic parameters that are fundamental information for lynx management in the study area as well as in similar contexts Europe-wide.
Robust monitoring of the Eurasian lynx Lynx lynx in the Slovak Carpathians reveals lower numbers than officially reported
Abstract The Eurasian lynx Lynx lynx population in the Carpathian Mountains is considered to be one of the best preserved and largest in Europe and hence is a source for past and current…
Multi-seasonal systematic camera-trapping reveals fluctuating densities and high turnover rates of Carpathian lynx on the western edge of its native range
TLDR
This study demonstrates that long-term camera-trapping surveys are needed for evaluation of population trends and for reliable estimates of demographic parameters of wild territorial felids, and can be further used for establishing successful management and conservation measures.
Hide and seek: extended camera-trap session lengths and autumn provide best parameters for estimating lynx densities in mountainous areas
Abstract A tool commonly used in wildlife biology is density estimation via camera-trap monitoring coupled with capture–recapture analysis. Reliable regional density estimations of animal populations…
Evaluating heterogeneity of sex‐specific capture probability and precision in camera‐trap population estimates of tigers
TLDR
To assess the reliability of abundance estimates, heterogeneity in sex-specific capture probabilities should be considered and using an SECR model is recommended because these methods appear to be minimally biased for estimating an effective sampled area and can be applied consistently among studies of various taxa.
A paradox of local abundance amidst regional rarity: the value of montane refugia for Persian leopard conservation
TLDR
The results show the benefits of protecting even relatively small mountainous areas, which accommodated a high density of leopards and provided refugia in a landscape with substantial human activity, and the effect of camera trap placement on detection probability.
Tiger density in a tropical lowland forest in the Eastern Himalayan Mountains
TLDR
This is the first systematic sampling study in tropical semi evergreen forests of India, and information on capture rate and population density of tigers provides baseline data from which to determining changes in the future to assist conservation.

TLDR

Natal dispersal of Eurasian lynx (Lynx lynx) in Switzerland
TLDR
Although only females took over the maternal home range, there was no significant sex bias in the proportion of individuals that dispersed in both populations, and successful dispersers settled in a territory at distances that differed between populations with effects of sex, but not condition.
