Open AccessEffect of sex, age, and reproductive status on daily activity levels and activity patterns in jaguars (Panthera onca)
All animals, including carnivores, adapt their daily activity duration and distribution to satisfy food demands, breed, or avoid mortality risk. We used the kernel density method to estimate daily movement act...

Open AccessChallenges and science-based implications for modern management and conservation of European ungulate populations
Wildlife management systems face growing challenges to cope with increasingly complex interactions between wildlife populations, the environment and human activities. In this position statement, we address the...

Open AccessDensity and population structure of the jaguar (Panthera onca) in a protected area of Los Llanos, Venezuela, from 1 year of camera trap monitoring
Density is crucial for understanding large carnivore ecology and conservation, but estimating it has proven methodologically difficult. We conducted 1 year of camera trap** to estimate jaguar (Panthera onca) de...

Open AccessA “death trap” in the landscape of fear
A crucial element in the “the landscape of fear” concept is that prey animals are aware of varying levels of predation risk at a spatial scale. This often leads to a negative spatial relationship between prey ...

Open AccessEdge effect and influence of economic growth on Eurasian lynx mortality in the Białowieża Primeval Forest, Poland
Eurasian lynx is one of most widely distributed felid species. However, populations in central Europe are strongly fragmented and limited to forest areas, which may influence their sustainability and gene flow...

Hair snaring and molecular genetic identification for reconstructing the spatial structure of Eurasian lynx populations
Non-invasive genetic sampling (NGS) is being increasingly applied in wildlife monitoring and population genetic research. This study was designed to evaluate the use of NGS for reconstructing the spatial struc...

Habitat suitability, corridors and dispersal barriers for large carnivores in Poland
Carnivores are often particularly sensitive to landscape fragmentation. Ecological corridors may help to connect local populations, ensuring gene flow and retaining viable meta-populations. We aimed to establi...

Microhabitat selection by Eurasian lynx and its implications for species conservation
We studied microhabitat selection of the Eurasian lynxLynx lynx (Linnaeus, 1758) at 116 hunting and 88 resting sites in Białowieża Primeval Forest (Poland) to describe its characteristics and determine the import...

Behavioural and spatial adaptation of the Eurasian lynx to a decline in prey availability
The distribution and abundance of food resources is a major factor influencing animal populations. I studied the effect of a roe and red deer population decline on diet composition, home range size and foragin...

Genetic diversity and relatedness within packs in an intensely hunted population of wolvesCanis lupus
A population of grey wolvesCanis lupus Linnaeus, 1758 inhabiting Białowieża Primeval Forest (BPF) on the Polish-Belarussian border has recovered after near extermination in the 1970s. Currently, it is intensively...

The process of a wolf pack splitting in Białowieża Primeval Forest, Poland
In 1998, the pack of 7 wolvesCanis lupus Linnaeus, 1758, radio-tracked in Białowieża Primeval Forest, East Poland, split into 2 packs (2 and 5 wolves), when an 8-year-old alpha female ceased breeding. The two sis...
