Significance
The cheetah is a prominent example for human–carnivore conflicts and mitigation challenges. Its global population suffered a substantial decline throughout its range. Here, we present an in-depth and new understanding of the socio-spatial organization of the cheetah. We show that cheetahs maintain a network of communication hubs distri...
Top-down suppression by apex predators can limit the abundance and spatial distribution of mesopredators. However, this phenomenon has not been studied over long time periods in human-dominated landscapes, where the strength of this process might be limited. Here, we used a multi-scale approach to analyse interactions between two canids in the huma...
The conservation of large carnivores is a formidable challenge for biodiversity conservation. Using a data set on the past
and current status of brown bears (Ursus arctos), Eurasian lynx (Lynx lynx), gray wolves (Canis lupus), and wolverines (Gulo gulo) in European countries, we show that roughly one-third of mainland Europe hosts at least one larg...
Many carnivores rely on marking behavior for intraspecific communication with potential mates and competitors, using scent and visual markings to advertise their use of a territory and allow potential mates to assess their quality. However, obtaining data on communication behaviors of rare and elusive animals can be challenging. To better understan...
Individual behavioral plasticity enables animals to adjust to different scenarios. Yet, personality traits limit this flexibility, leading to consistent interindividual differences in behavior. These individual behavioral traits have the potential to govern community interactions, although testing this is difficult in complex natural systems. For l...
The recovery of wolves (Canis lupus) across Europe is a notable conservation success in a region with extensive human alteration of landscapes and high human population densities. We provide a comprehensive update on wolf populations in Europe, estimated at over 21,500 individuals by 2022, representing a 58% increase over the past decade. Despite t...
Survival and cause‐specific mortality rates are vital for evidence‐based population forecasting and conservation, particularly for large carnivores, whose populations are often vulnerable to human‐caused mortalities. It is therefore important to know the relationship between anthropogenic and natural mortality causes to evaluate whether they are ad...
Inbreeding depression poses a severe threat to small populations, leading to the fixation of deleterious mutations and decreased survival probability. While the establishment of natural gene flow between populations is an ideal long‐term solution, its practical implementation is often challenging. Reinforcement of populations by translocating indiv...
The estimation of foraging parameters is fundamental for understanding predator ecology. Predation and feeding can vary with multiple factors, such as prey availability, presence of kleptoparasites and human disturbance. However, our knowledge is mostly limited to local scales, which prevents studying effects of environmental factors across larger...
Translocations are central to large carnivore restoration efforts, but inadequate monitoring often inhibits effective conservation decision-making. Extinctions, reintroductions, poaching and high inbreeding levels of the Central European populations of Eurasian lynx (Lynx lynx) typify the carnivore conservation challenges in the Anthropocene. Recen...
Geodiversity, encompassing various geophysical elements, can have an important impact on species distribution and affect animal behaviour patterns. Although many wild felids are attracted to rugged terrain and conspicuous relief features, most previous research was limited to general topographical characteristics (e.g., slope or terrain ruggedness)...
Context
Many carnivores are attracted to rugged terrain, rocky areas, and conspicuous relief features. However, most of the previous research is limited to general topographical habitat characteristics and rarely consider the effects of microhabitat characteristics.
Objectives
We used the Eurasian lynx (Lynx lynx) as a model species to investigate...
The report Large carnivore distribution maps and population updates 2017 – 2022/23 is based on the latest information and provides the best available overview of brown bear (Ursus arctos), Eurasian lynx (Lynx lynx), wolf (Canis lupus), golden jackal (Canis aureus), and wolverine (Gulo gulo) distributions and population sizes at a European continent...
Most large carnivore populations have increased in recent decades in Europe. Along with the adoption of the EU Habitats Directive in 1992, the EU launched a funding program entirely dedicated to environment, nature protection and climate action, the European LIFE programme. Here, we explore the investment of this programme in large carnivore conser...
Wildlife must adapt to human presence to survive in the Anthropocene, so it is critical to understand species responses to humans in different contexts. We used camera trapping as a lens to view mammal responses to changes in human activity during the COVID-19 pandemic. Across 163 species sampled in 102 projects around the world, changes in the amo...
The current rapid climate change and human-induced alteration of landscapes and animal communities have led to range expansions in numerous species, raising concerns about potential negative impacts on genetic diversity, biotic interactions and hybridization with related species in newly colonized areas, and the need to adjust management plans. The...
Spotted hyenas (Crocuta crocuta) are known for their flexible foraging behavior and trophic interactions with diverse prey species. However, most studies describing their hunting behavior are focused on predation of large prey. Here we describe the capture rates and behavior of adult and subadult spotted hyenas hunting passerine birds. Hyenas were...

Besides being one of the most charismatic animal species in the world, the lion is also among the best studied wild mammals. This largely results from our ability to directly observe them over extended periods, which is more an exception than a rule for large carnivores and is connected with lions’ preference for open habitats and their tolerance t...
Aim: The increasing availability of animal tracking datasets collected across many
sites provides new opportunities to move beyond local assessments to enable detailed and consistent habitat mapping at biogeographical scales. However, integrating wildlife datasets across large areas and study sites is challenging, as species' varying responses to d...
Larger landforms such as valleys, ridges, or dolines can be easily detected with a number of already developed (semi-)automatic detection methods, while smaller features like rocky outcrops (i.e., cliffs, rocky blocks, rocky ridges, rock shelters, boulders, karrens and similar rocky features) are harder to detect. Field mapping or digitizing would...

Aim
Physiological and metabolic performance are key mediators of the functional response of species to environmental change. Few environments offer such a multifaceted array of stressors as high‐altitude habitats, which differ markedly in temperature, water availability, UV radiation and oxygen pressure compared to low‐altitude habitats. Species th...
Integrating data across studies with traditional microsatellite genetic markers requires careful calibration and represents an obstacle for investigation of wide-ranging species where populations require transboundary management. We used the “yardstick” method to compare results published across Europe since 2002 and new wolf (Canis lupus) genetic...
Olfactory communication is important for many solitary carnivores to delineate territories and communicate with potential mates and competitors. Pallas’s cats (Otocolobus manul) are small felids with little published research on their ecology and behaviour, including if they avoid or change behaviours due to dominant carnivores. We studied their ol...
Estimating abundance of wild animal populations is crucial for their management and conservation. While spatial capture-recapture models are becoming increasingly common to assess the densities of elusive species, recent studies have indicated potential bias that can be introduced by unaccounted spatial variation of detectability. We used camera-tr...
COVID-19 lockdowns in early 2020 reduced human mobility, providing an opportunity to disentangle its effects on animals from those of landscape modifications. Using GPS data, we compared movements and road avoidance of 2300 terrestrial mammals (43 species) during the lockdowns to the same period in 2019. Individual responses were variable with no c...
Artificial feeding of wildlife is a widespread, but controversial, management practice with many positive and negative effects. Besides the effects on the target species, it can also affect other (non-target) species by modulating interspecific interactions. Previous research showed that the presence of artificial feeding sites for bears and ungula...
Golden jackal (Canis aureus) has dramatically increased its distribution and abundance in Europe. Expansion is now reaching
parts of Central, Northern, and Western Europe, where jackal occurrences are mainly limited to vagrants or single territorial
groups. Currently, it is hard to predict future development of jackal populations in these regions,...

Adjustments in habitat use by large carnivores can be a key factor facilitating their coexistence with people in shared landscapes. Landscape composition might be a key factor determining how large carnivores can adapt to occurring alongside humans, yet broad-scale analyses investigating adjustments of habitat use across large gradients of...
Report on monitoring of Eurasian lynx Dinaric-SE Alpine population for monitoring year 2021-2022
Mesopredators abundance is often limited by top‑order predators and also by key food resources. However, the contribution of these bidirectional forces to structure carnivore community is still unclear. Here, we studied how the presence and absence of an apex predator which is currently recovering its former distribution range, the Iberian lynx (Ly...
Globally, fragmented landscapes and other anthropogenic pressures are causing declines in large carnivore populations. Conservation organizations are working to counteract these trends through the translocations of large carnivores, for example by reintroducing them to their historic ranges or by reinforcing existing populations to promote gene flo...
Kill rates are a central parameter to assess the impact of predation on prey species. An accurate estimation of kill rates requires a correct identification of kill sites, often achieved by field‐checking GPS location clusters (GLCs). However, there are potential sources of error included in kill‐site identification, such as failing to detect GLCs...
Translocations of individuals for reintroductions and population reinforcements have been increasingly used in carnivore conservation. Movement is the first behavioural response of reintroduced animals to ‘forced dispersal’ in a new habitat and our study investigated space use and movement patterns of six male Eurasian lynx (Lynx lynx) translocated...
In many early European cultures, humans shared an overall positive view of the wolf. But this changed with the anthropocentric view of nature brought about by Christianity as well as with the process of domestication and the advent of extensive
animal husbandry. Wolves were then strongly persecuted, leading to their extirpation in almost all their...
The arrival of a new carnivore can have important effects on local communities. While several effects of introduced alien species have been well documented, few studies have reported the ecological consequences of an expanding native species. Golden jackals (Canis aureus) are rapidly expanding their distribution in Europe, far beyond their historic...
Automatic methods for detecting and delineating relief features allow remote and low-cost mapping, which has an outstanding potential for large-scale spatial analysis and calculation of morphometric characteristics of karst depressions in remote, forested and hard to cross areas. Besides geomorphology, detection methods can be also useful for wildl...

The ecology and evolution of reproductive timing and synchrony has been a topic of great interest in evolutionary ecology for decades. Originally motivated by questions related to behavioural and reproductive adaptation to environmental conditions, the topic has acquired new relevance in the face of climate change. However, there has been relativel...
Bears are the largest terrestrial carnivores, and most bear species can be characterized as opportunistic omnivores. An infrequent foraging tactic for bears is cannibalism, where a bear consumes a conspecific individual, either through scavenging or following intraspecific predation. Although several reports of cannibalism events are known, no atte...
Selecting appropriate candidates for genetic rescue mostly relies on previous genetic research and monitoring, while ecological and behavioural traits of the remnant and source populations are rarely considered for such conservation measures. Because of their slow recovery, Eurasian lynx Lynx lynx populations in Central and Western Europe have been...
Mammalian communities inhabiting temperate grasslands are of conservation concern globally, especially in Central Asia, where livestock numbers have dramatically increased in recent decades, leading to overgrazing and land‐use change. Yet, how this pervasive presence of livestock herds affects the community of wild mammals remains largely unstudied...
The project focuses on interactions among wild felids in Europe and Africa, but also includes research on other aspects of felid ecology in other parts of the world. Project aims • Study patterns of avoidance and attraction among the selected species of cats in space and time • Obtain novel insights into indirect communication among different cats...

Aim:
Macroecological studies that require habitat suitability data for many species often derive this information from expert opinion. However, expert-based information is inherently subjective and thus prone to errors. The increasing availability of GPS tracking data offers opportunities to evaluate and supplement expert-based information with de...
The grey wolf (Canis lupus) persists in a variety of human-dominated landscapes and is subjected to various legal management regimes throughout Europe. Our aim was to assess the effects of intrinsic and methodological determinants on the hair cortisol concentration (HCC) of wolves from four European populations under different legal management. We...
Movement is a fundamental process in animal ecology. For many species, such as large carnivores, movement patterns are greatly shaped by a combination of ecological and anthropogenic factors. Understanding how these factors impact the roaming capacity of large carnivores is essential to forecast risks and design long‐term conservation strategies. T...
Regular assessments of species’ status are an essential component of conservation planning and adaptive management. They allow the progress of past or ongoing conservation actions to be evaluated and can be used to redirect and prioritise future conservation actions. Most countries perform periodic assessments for their own national adaptive manage...
Habitat selection is a multi-scale process driven by trade-offs between benefits, such as resource abundance, and disadvantages, such as the avoidance of risk. The latter includes human disturbances, to which large carnivores, with their large spatial requirements, are especially sensitive. We investigated the ecological processes underlying multi-...
Automatic methods for detecting and delineating relief features allow remote and low-cost mapping, which has an outstanding potential for wildlife ecology and similar research. We applied a filled-DEM (digital elevation model) method using LiDAR (Light Detection and Ranging) data to automatically detect dolines and other karst depressions in a rugg...
The snow leopard Panthera uncia is an elusive and globally-threatened apex predator occurring in the mountain ranges of central Asia. As with other large carnivores, gaps in data on its distribution and abundance still persist. Moreover, available density estimates are often based on inadequate sampling designs or analytical approaches. Here, we us...
Successful conservation depends on accurate taxonomy. Currently, the taxonomy of canids in Africa, Eurasia and Australasia is unstable as recent molecular and morphological studies have questioned earlier phenetic classifications. We review available information on several taxa of Old World and Australasian Canis with phylogenetic uncertainties (na...
Introduction to the broad public of the InterMuc Project in Namibia
What would successful deer management look like in Scotland? To some, flourishing
populations of native wild deer represent success. But to others, negative impacts
such as damage to woodlands and peatlands, agricultural and forestry losses, deer-
vehicle collisions, and facilitating Lyme disease spread represent failure. Conflicting
interests and...
Eurasian lynx Lynx lynx was reintroduced to the Dinaric Mountains in 1973 to bring back an extinct autochthonous keystone species, but also to enrich the hunting grounds. The institutions involved in the reintroduction were aware of the danger of genetic isolation and warned about the importance of connectivity between the lynx populations in the D...
Globally, fragmented landscapes and anthropogenic pressures are causing steep declines in large carnivore populations. Conservation organizations are working to counteract these trends through the reintroduction of large carnivores and translocations within existing populations to promote gene flow and resilience.

Species assemblages often have a non‐random nested organization, which in vertebrate scavenger (carrion‐consuming) assemblages is thought to be driven by facilitation in competitive environments. However, not all scavenger species play the same role in maintaining assemblage structure, as some species are obligate scavengers (i.e., vultures) and ot...
In countries such as Mongolia, where globalization of the cashmere market has spurred herders to massively increase their livestock numbers, an important conservation concern is the effect of livestock encroachment on wildlife. This is especially important inside protected areas (PAs), which often represent the last refugia for threatened large mam...
Governments around the world invest considerable resources to reduce damages caused by large carnivores on human property. To use these investments more efficiently and effectively, we need to understand which interventions successfully prevent such damages and which do not. In the European Union, the LIFE program represents by far the largest fina...
Organisms face numerous environmental stressors, which can affect developmental precision, including symmetry of various physical characteristics. Fluctuating asymmetry (FA) has therefore been suggested as a simple and efficient tool for assessing sub-lethal stress levels. We analyzed FA in two sympatric lizard species (Iberolacerta horvathi and Po...

Worldwide, unsustainable use of nature threatens many ecosystems and the services they provide for a broad diversity of life, including humans. Yet, governments commonly claim that the best available science supports their policies governing extraction of natural resources. We confront this apparent paradox by assessing the complexity of the inters...
Snow leopards (Panthera uncia) are apex predators in Asian mountainous ecosystems, mostly hunting wild and domestic ungulates up to three times their size. Here we report on a predation event of a male snow leopard killing a semi-domestic adult yak (about five times the body weight of the predator) from the Altai mountain range in Mongolia. We used...
Scent-marking is a predominant form of communication among felids, with urine spraying having a key role. Detectability and longevity of scent marks are recognized as crucial for efficiency of scent-marking, but there is limited research that has tested scent persistence with respect to various environmental factors. We used an experimental framewo...
The Horvath’s rock lizard Iberolacerta horvathi (Méhely, 1904) is an understudied lacertid species, which is geographically isolated from its congeners and currently classified as Near Threatened under IUCN red listing criteria. Due to its limited distribution and narrow environmental preferences, we expect that the species had been affected by pas...
While scavenging has been repeatedly reported for several felid species, surprisingly little information is available on scavenging behavior of the European wildcat (Felis silvestris). To fill this knowledge gap, we used camera traps to document scavenging behavior at the 48 experimentally-set deer carcasses at random locations throughout the year....
The encounter rates carnivores have with prey are dependent on spatial and temporal overlap, and are often highest with their preferred prey. Sumatran tigers Panthera tigris sumatrae are critically endangered and dependent on prey populations, but little is known about their prey preferences. We collected 7 years of camera trapping data from Bukit...
Grey wolf (Canis lupus) populations are expanding across Europe, which leads to increase in their interactions with people and domestic animals, including dogs. Attacks on hunting dogs are becoming a major cause for conflicts between wolves and hunters in many countries, including Croatia, where this conflict has increased dramatically in recent ye...
Eurasian lynx (Lynx lynx) is a crepuscular-nocturnal carnivore and mostly spends daytime resting. Although resting sites represent an important part of the lynx habitat and can be negatively affected by human activities, it is still poorly known how lynx select these sites, especially in regions with rugged topography characteristic for much of the...
Aim
The recent recovery of large carnivores in Europe has been explained as resulting from a decrease in human persecution driven by widespread rural land abandonment, paralleled by forest cover increase and the consequent increase in availability of shelter and prey. We investigated whether land cover and human population density changes are relat...
This project report describes the current progress of the reinforcement of the lynx population in the Dinaric Mountains and Southeastern (SE) Alps as part of the LIFE Lynx project (LIFE16 NAT/SI/000634). It represents the results of the first comprehensive transboundary lynx survey in this region, covering the lynx population distribution in Sloven...
The occurrence of carnivore species in wolf diet has been overlooked and poorly studied despite the potential implications for wolf ecology and wildlife management. We conducted an extensive literature review, focusing on 120 wolf diet studies worldwide to assess global patterns of carnivore consumption by wolves and their ecological and human-rela...
Large carnivores, such as brown bears (Ursus arctos), wolves (Canis lupus), and tigers (Panthera tigris), can play a key ecological role from their apex position in trophic systems. Within the overall context of bottom-up and top-down regulation of ecosystems, predation by large carnivores often induces demographic and behavioral changes in prey sp...
Conflicts between humans and bears have occurred since prehistory. Through time, the catalogue of human–bear conflicts (HBC) has been changing depending on the values and needs of human societies and their interactions with bears. Even today, conflict situations vary among the eight species of bears and geographically across these species’ ranges....
Bears have fascinated people since ancient times. The relationship between bears and humans dates back thousands of years, during which time we have also competed with bears for shelter and food. In modern times, bears have come under pressure through encroachment on their habitats, climate change, and illegal trade in their body parts, including t...
The media and scientific literature are increasingly reporting an escalation of large carnivore attacks on humans, mainly in the so-called developed countries, such as Europe and North America. Although large carnivore populations have generally increased in developed countries, increased numbers are not solely responsible for the observed rise in...
Large carnivore conservation is important for ecosystem integrity and understanding drivers of their abundance is essential to guide conservation efforts. Leopard (Panthera pardus) populations are in a general state of decline, although local studies demonstrated large variation in their population trends and density estimates vary widely across th...
Kill rates of predators typically increase when they come into contact with naïve and abundant prey. Such a situation can lead to surplus killing or the occurrence of parallel kills (i.e. additional kills that predator makes while still consuming the carcass from the previous kill). However, there is limited information on the feeding behaviour of...
Knowledge about breeding biology is often incomplete in species with complex reproductive strategies. The brown bear Ursus arctos is a polygamous seasonal breeder inhabiting a wide variety of habitats and environmental conditions. We compiled information about brown bear breeding season dates from 36 study areas across their distribution range in t...
Evidence-based management of large carnivores is a crucial step towards their effective conservation. However, monitoring of these populations is demanding and generally requires substantial fieldwork effort. Lately, citizen science has become an increasingly important part of wildlife monitoring, but can that endanger studied species? In this pape...
Rapid and widespread biodiversity losses around the world make it important to survey and monitor endangered species, especially in biodiversity hotspots. Bukit Barisan Selatan National Park (BBSNP) is one of the largest conserved areas on the island of Sumatra, and is important for the conservation of many threatened species. Sumatran tigers (Pant...
The organization of ecological assemblages has important implications for ecosystem functioning, but little is known about how scavenger communities organize at the global scale. Here, we test four hypotheses on the factors affecting the network structure of terrestrial vertebrate scavenger assemblages and its implications on ecosystem functioning....
Eurasian lynx is the largest felid in Europe, where many populations still face extinction. Major threats include poaching, inbreeding depression, vehicle collisions, habitat loss and fragmentation. To preserve viability of these populations, further efforts are required, including an efficient monitoring that represents an important part of any su...
Spatial and foraging ecology of the Eurasian lynx (Lynx lynx) has been well recognized, however due to the distinct taxonomic position and geographic isolation of its Balkan population, it is important to learn and compare its ecology to other populations of this felid. Therefore, the paper offers the first ever investigation into the spatial and f...
Rapid, global changes, such as extinction and climate change, put a premium on evidence-based, environmental policies and interventions, including predator control efforts. Lack of solid scientific evidence precludes strong inference about responses of predators, people, and prey of both, to various types of predator control. Here we formulate two...
