Abstract Aim In the light of human‐induced rapid environmental change ( HIREC ), populations are exposed to ever‐greater bioclimatic stress at edge a species’ historic range. The distribution dynamics European badgers Meles meles ) their southern linked tightly climatic variability. We contribute critical data on how context and local factors determine site occupancy in northern‐range population. Location Eleven study areas (averaging ~21.3 km 2 spread over ~50,000 Northern Scotland. Methods...
Apex predator reintroductions have proliferated across southern Africa, yet their ecological effects and proposed umbrella benefits of associated management lack empirical evaluations. Despite a rich theory on top-down ecosystem regulation via mesopredator suppression, knowledge gap exists relating to the influence lions ( Panthera leo ) over Africa's diverse mesocarnivore (less than 20 kg) communities. We investigate how geographical variation in community richness occupancy South African...
Abstract Conservation efforts in South Africa play out across multi‐use landscapes where formal protected areas coexist with private wildlife business (ecotourism and/or hunting) a human‐dominated matrix. Despite the persistence of highly diverse carnivore guilds, management idiosyncrasies are often orientated towards charismatic large predators and assemblage‐level patterns remain largely unexplored. We conducted an extensive camera‐trap survey natural quasi‐experimental setting...
Theory on intraguild killing (IGK) is central to mammalian carnivore community ecology and top-down ecosystem regulation. Yet, the cryptic nature of IGK hinders empirical evaluations. Using a novel data source - online photographs interspecific aggression between African carnivores we revisited existing predictions about extent drivers IGK. Compared with seminal reviews, our constructed network yielded 10 more species nearly twice as many interactions. The interactions increased 37% when...
Abstract Fires are common in many ecosystems world‐wide, and frequently used as a management tool. Although the responses of herbivores to fire have been well‐studied, carnivores remain unclear. In particular, post‐fire habitat changes, associated changes prey availability, might affect coexistence or competition carnivore species within larger community, but few studies focused on how fires influence multiple simultaneously. Using South African our focal we explored relative intensity use...
South Africa’s decentralized approach to conservation entails that wildlife outside formally protected areas inhabit complex multi-use landscapes, where private business (ecotourism and/or hunting) co-exist in a human-dominated landscape matrix. Under conservation, is perceived benefit from increased amount of available habitat, however it crucial understand how distinct management priorities and associated modifications impact noncharismatic taxa, such as small mammals. We conducted...
Compound effects of anthropogenic disturbances on wildlife emerge through a complex network direct responses and species interactions. Land-use changes driven by energy forestry industries are known to disrupt predator-prey dynamics in boreal ecosystems, yet how these disturbance propagate across mammal communities remains uncertain. Using structural equation modeling, we tested disturbance-mediated pathways governing the spatial structure multipredator multiprey networks landscape-scale...
Across the Mediterranean, conservation programmes often operate concomitantly with hunting interests within game-lands. Carnivore guilds lie at interface between contrasting management goals, being simultaneously fundamental components of ecosystems and targets predator control to reduce predation on game species. Here, we evaluate composition spatial structure a mesocarnivore community in protected area Southeast Portugal, high economic investment significant activity. Between June August...
Abstract The patterns of species co-occurrence have long served as a primary approach to explore concepts interspecific interaction. However, the interpretation such is difficult they can result from several complex ecological processes, in scale-dependent manner. Here, we aim investigate pattern between European rabbit and wild boar an estate Central Portugal, using two-species occupancy modelling. With this framework, tested interaction for detection, but also interdependencies both...
Carnivore intraguild dynamics depend on a complex interplay of environmental affinities and interspecific interactions. Context-dependency is commonly expected with varying suites interacting species conditions but seldom empirically described. In South Africa, decentralized approaches to conservation the resulting multi-tenure landscapes have markedly altered stage that shapes structure local carnivore assemblages. We explored assemblage-wide patterns spatial (residual occupancy...
