Great leaps forward in scientific understanding are often spurred by innovations technology. The explosion of miniature sensors that driving the boom consumer electronics, such as smart phones, gaming platforms, and wearable fitness devices, now becoming available to ecologists for remotely monitoring activities wild animals. While half a century ago researchers were attaching balloons backs seals measure their movement, today have access an arsenal can continuously most aspects animal's...
Large carnivores' fear of the human ‘super predator’ has potential to alter their feeding behaviour and result in human-induced trophic cascades. However, it yet be experimentally tested if large carnivores perceive humans as predators react strongly enough have cascading effects on prey. We conducted a predator playback experiment exposing pumas (human) non-predator control (frog) sounds at puma sites measure immediate responses subsequent impacts feeding. found that fled more frequently,...
The fear induced by predators on their prey is well known to cause behavioural adjustments that can ripple through food webs. Little known, however, about the analogous impacts of humans as perceived top foraging behaviour carnivores. Here, we investigate influence human-induced puma using location and consumption data from 30 tagged individuals living along a gradient human development. We observed strong responses female pumas development, whereby fidelity kill sites overall time declined...
Anthropogenic disturbances can constrain the realized niche space of wildlife by inducing avoidance behaviors and altering community dynamics. Human activity might contribute to reduced partitioning carnivores that consume similar resources, both promoting tolerant species while also behavior (e.g. patterns). We investigated influence anthropogenic disturbance on habitat dietary breadth overlap among competing carnivores, explored if altered resource could be explained human‐induced shifts....
Abstract Understanding the distribution of biodiversity across Earth is one most challenging questions in biology. Much research has been directed at explaining species latitudinal pattern showing that communities are richer tropical areas; however, despite decades research, a general consensus not yet emerged. In addition, global patterns being rapidly altered by human activities. Here, we aim to describe large‐scale richness and diversity terrestrial vertebrate scavenger...
Abstract Research on the ecology of fear has highlighted importance perceived risk from predators and humans in shaping animal behavior physiology, with potential demographic ecosystem‐wide consequences. Despite recent conceptual advances management implications fear, theory conservation practices have rarely been linked. Many challenges may be alleviated by actively harnessing or compensating for perception avoidance wild populations. Integration into practice can contribute to recovery...
Abstract The spatial relationship between predator and prey is often conceptualized as a behavioral response race, in which avoid predators while track prey. Limiting habitat types can create anchors for or predators, influencing the likelihood that will dominate. Joint emerge when occupy similar feeding domains risk reward become spatially conflated, confusing predictions of player win space race. These dynamics risk‐foraging trade‐offs are obscured by heterogeneity community complexity...
Predation risk, the probability that a prey animal will be killed by predator, is fundamental to theoretical and applied ecology. risk varies with behavior environmental conditions, yet attempts understand predation in natural systems often ignore important ecological complexities, relying instead on proxies for actual such as predator–prey spatial overlap. Here we detail complexities driving disconnects between three stages of sequence are assumed tightly linked: overlap, encounters...
The discipline of ecology and evolutionary biology (EEB) has long grappled with issues inclusivity representation, particularly for individuals systematically excluded marginalized backgrounds or identities. For example, significant representation disparities still persist that disproportionately affect women gender minorities; Black, Indigenous, People Color (BIPOC); disabilities; people who are LGBTQIA+. Recent calls action have urged the EEB community to directly address inclusion,...
ABSTRACT Understanding how anthropogenic development affects food webs is essential to implementing sustainable growth measures, yet little known about the spatial configuration of residential foraging behavior and prey habits top predators. We examined influence characteristics on composition in puma ( Puma concolor ). located remains kills from 32 pumas fitted with global positioning system (GPS) satellite collars determine housing most influencing size species composition. differences...
Abstract Migratory ungulates are thought to be declining globally because their dependence on large landscapes renders them highly vulnerable environmental change. Yet recent studies reveal that many ungulate species can adjust migration propensity in response changing conditions potentially improve population persistence. In addition the question of whether migrate, decisions where and when migrate appear equally fundamental individual tactics, but these three dimensions plasticity have...
Human activity has rapidly transformed the planet, leading to declines of animal populations around world through a range direct and indirect pathways. Humans have strong numerical effects on wild populations, as highly efficient hunters unintentional impacts human development. disturbance also induces costly non-lethal by changing behavior risk-averse animals. Here, we suggest that unique strength these lethal is amplified mismatches between nature risk associated with anthropogenic stimuli...
Human development strongly influences large carnivore survival and persistence globally. Behavior changes are often the first measureable responses to human disturbances, can have ramifications on animal populations ecological communities. We investigated how a responds anthropogenic disturbances by measuring activity, movement behavior, energetics in pumas along housing density gradient. used log-linear analyses examine habitat, time of day, proximity influenced activity patterns both male...
Mate selection influences individual fitness, is often based on complex cues and behaviours, can be difficult to study in solitary species including carnivores. We used motion-triggered cameras at 29 community scrapes (i.e. scent marking locations by multiple individuals) home range data from 39 GPS-collared pumas (Puma concolor) assess the relevance of communication behaviours for mate female California. Female visited irregularly visitation bouts appeared correlated with oestrus. average...
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 factors affecting network structure terrestrial vertebrate and its functioning. We expect to be more nested (i.e. structured): 1) in species‐rich productive regions, as nestedness been linked high competition carrion resources, 2) regions with low human impact, because most efficient...
Abstract Predator–prey games emerge when predators and prey dynamically respond to the behavior of one another, driving outcomes predator–prey interactions. Predation success is a function combined probabilities encountering capturing prey, which are influenced by both environmental features. While relative importance encounter capture have been evaluated in spatial framework, temporal variation intrinsic catchability likely also affect distribution predation events. Using...
Abstract Species assemblages often have a non‐random nested organization, which in vertebrate scavenger (carrion‐consuming) is thought to be driven by facilitation competitive environments. However, not all species play the same role maintaining assemblage structure, as some are obligate scavengers (i.e., vultures) and others facultative, scavenging opportunistically. We used database with 177 from 53 22 countries across five continents identify functional traits of key network structure....
Abstract Human activities catalyse risk avoidance behaviours in wildlife across taxa and systems. However, the broader ecological significance of human‐induced perception remains unclear, with a limited understanding how phenotypic responses scale up to affect population or community dynamics. We present framework informed by predator–prey ecology predict occurrence non‐consumptive effects (NCE) trait‐mediated indirect (TMIE) anthropogenic disturbances. report evidence from comprehensive...
