Article
The recovery of European wild rabbit (Oryctolagus cuniculus) populations in Spain is of great interest for wildlife conservation. Large-scale management and conservation programmes aimed to determine current population abundance. Most methods for censusing rabbits only offer estimates of relative abundance. However, we lack accurate studies about h...

Transportation infrastructure are one of the main threats for the conservation of many vertebrate species. Although many animals die every day on roads, mammal carnivores are one of the most susceptible groups due to their low reproductive rates, large home ranges, and high mobilities, also most of them are threatened. A better understanding of how...

Anticoagulant rodenticides can help to reduce rodent overpopulations in agricultural areas, but they also produce harmful effects on natural predators when ingested directly or by consuming poisoned preys. We aimed to study the presence of rodenticides in the European polecat (Mustela putorius), a renowned rodent consumer. Forty livers of roadkille...

The correct interpretation of relative abundance indices provided by different sampling methods is essential to correctly estimate population size. Although multiple indices and models have been proposed, their ability to estimate relative abundances and their performance in models explaining abundance trends remains unclear. We used the red fox (V...

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...

Apex predators play key roles in food webs and their recovery can trigger trophic cascades in some ecosystems. Intra-guild competition can reduce the abundances of smaller predators and perceived predation risk can alter their foraging behaviour thereby limiting seed dispersal by frugivorous carnivores. However, little is known about how plant–frug...

Las recientes recolonizaciones y reintroducciones de grandes depredadores ofrecen una oportunidad única para estudiar su efecto en la cadena trófica y en la dinámica del ecosistema. Algunas funciones ecosistémicas como la dispersión de semillas podrían verse afectadas por una cascada trófica que involucre interacciones entre depredadores. Aquí, que...
Article
Global change affects species and ecosystems by modifying population dynamics and the function and structure of ecosystems. The effects of drivers of global change on species depend on their traits and the location of each population within their geographical distribution area. For example, the quality of the niche decreases at the limit of the geo...

Climate change is forcing the redistribution of life on Earth at an unprecedented velocity1,2. Migratory birds are thought to help plants to track climate change through long-distance seed dispersal3,4. However, seeds may be consistently dispersed towards cooler or warmer latitudes depending on whether the fruiting period of a plant species coincid...

The Egyptian mongoose (Herpestes ichneumon) is a carnivore in expansion on the western limits of Europe, where its reproductive ecology is unknown. In this study, we weighed and measured the gonads of 507 wild-caught mongooses ranging its geographical distribution and all seasons of the year. Based on the variation in gonad weight, we determined pe...

Top predators shape the communities of sympatric predators by killing and displacing smaller predators. Predation risk pushes smaller predators to select enemy-free spaces irrespective of food availability, which results in changes in their behaviour, space use, distribution, and abundance. Although the landscape of fear dynamics are known for top...

The human abandonment of rural areas facilitates rewilding, which is also supported by European projects and initiatives. Rewilding often implies the return of iconic predators such as the wolf (Canis lupus), leading to human–wildlife conflicts. To reverse human depopulation, initiatives such as the European Union’s Common Agricultural Policy (CAP)...

: The honey badger (Mellivora capensis) is a medium-sized carnivore distributed throughout Africa to the Arabian Peninsula, Iran, Turkmenistan, and India. However, available information on its ecology is very scarce. We studied its feeding ecology in the remote north-western Sahara Desert, based on the contents of 125 fecal samples collected during...

Knowledge of population dynamics of threatened species in the wild is key to effective conservation actions. However, at present, there are many examples of endangered animals for which their current situation is unknown, and not just in remote areas and less developed countries. We have explored this topic by studying the paradigmatic case of the...

Free-range livestock grazing is a widespread human activity that not only modifies natural vegetation but also leads to interactions with wild ungulates. Most commonly, the interactions between cattle and wild ungulates have been studied with a focus on competition for high-quality forage. However, other mechanisms, such as the risk of parasite inf...

The European badger has a wide distribution range, having been the target of many studies regarding e.g. distribution, abundance, population dynamics, ecology and morphological traits. In a recent study, a correlation was established between badgers body size and latitude with the biggest badgers being those from populations within the core of the...

Human-Induced Rapid Environmental Change (HIREC), particularly climate change and habitat conversion, affects species distributions worldwide. Here, we aimed to (i) assess the factors that determine range patterns of European badger (Meles meles) at the southwestern edge of their distribution and (ii) forecast the possible impacts of future climate...

Studies that assess the conservation status of the megafauna of the Sahara desert are becoming more necessary given of the collapse of its populations have suffered in this last century. In this remote region of the planet, any work in situ poses severe challenges to logistic level and security, due to its remoteness, lack of infrastructure, extrem...

Scent-marking is a common behaviour among mammals with different functions including territory marking. However, this behaviour has high energy costs and thus a territory owner must select the most strategic sites to place its scent marks. We hypothesised that the scent-marking behaviour of the Iberian lynx (Lynx pardinus), an endangered feline and...

Wildlife monitoring is essential for assessing the size of species of conservation or management concern. Wildlife monitoring could be undertaken by selected volunteers when limited resources are available. Here, we study the sources of variation in the detectability of red fox scats and to improve the monitoring of the species by means of voluntee...

Scent-marking is a common behaviour among mammals with different functions. This behaviour implies high energy costs and thus, a territory owner must select the most strategic sites to place the scent marks. Our objective was to determine the effects of rabbit density and landscape structure on the faecal-marking patterns of the Iberian lynx.

European badgers (Meles meles) are considered central-place foragers, whose spatial ecology is predominantly determined by sett location. Many studies have assessed the factors determining sett site selection throughout this species’ range, but these have often been geographically limited and have primarily identified locally dependent factors. To...

Climate change is not only evident, but its implications on biodiversity are already patent. The scientific community has delved into the limitations and capabilities of species to face changes in climatic conditions through experimental studies and, primarily, Species Distribution Models (SDMs). Nevertheless, the widespread use of SDMs comes with...

The Egyptian mongoose (Herpestes ichneumon Linnaeus, 1758) is an expanding species, whose presence in Europe is restricted to its western extreme. Mongooses are generalist and opportunistic carnivores which is reflected by their anatomical features and nutritional preferences. With the purpose to fully characterize mongoose diet and ascertain if ga...

How species use space and time is central in ecology and evolution as well as for the conservation and management of vulnerable species. Unfortunately, this information is scarce for elusive species such as the threatened European wildcat (Felis silvestris silvestris), especially in Mediterranean areas. Using radio-tracking and camera-trapping, we...
