Meaningful comparison of variation in quantitative trait requires controlling for both the dimension varying entity and factor generating variation. Although coefficient (CV; standard deviation divided by mean) is often used to measure compare traits, it only accounts former, its use comparing may sometimes be inappropriate. Here, we discuss CV measures evolvability phenotypic plasticity, two variational properties traits. Using a dimensional analysis, show that contrary evolvability,...
Significance Many ecological and evolutionary processes strongly depend on the way natural selection varies over time. However, a gap remains when trying to connect theoretical predictions empirical work this question: Most theory assumes that adaptation involves tracking moving optimum phenotype through time, but is seldom estimated empirically. Here, we have assembled large database of wild bird mammal populations, estimate patterns fluctuations in breeding date its influence variability...
Abstract Extreme climate events often cause population crashes but are difficult to account for in population-dynamic studies. Especially long-lived animals, density dependence and demography may induce lagged impacts of perturbations on growth. In Arctic ungulates, extreme rain-on-snow ice-locked pastures have led severe crashes, indicating that increasingly frequent could destabilize populations. Here, using empirically parameterized, stochastic models High-Arctic wild reindeer, we show...
The slow–fast continuum is a commonly used framework to describe variation in life-history strategies across species. Individual life histories have also been assumed follow similar pattern, especially the pace-of-life syndrome literature. However, whether explains among individuals within population remains unclear. Here, we formally tested for presence of both populations and species using detailed long-term individual-based demographic data 17 bird mammal with markedly different...
Exploitation by humans affects the size and structure of populations. This has evolutionary demographic consequences that have typically being studied independent one another. We here applied a framework recently developed applying quantitative tools from population ecology selection gradient analysis to quantify on trait-birth date-through its association with multiple fitness components. From long-term monitoring (22 years) wild boar (Sus scrofa scrofa) subject markedly increasing hunting...
Climate change will affect the population dynamics of many species, yet consequences for long-term persistence populations are poorly understood. A major reason this is that density-dependent feedback effects caused by fluctuations in size considered independent stochastic variation environment. We show an interplay between winter temperature and density can influence a small passerine under global warming. Although warmer winters favor increased mean size, cause local to be less buffered...
Abstract Mast seeding in temperate oak populations shapes the dynamics of seed consumers and numerous communities. responds positively to warm spring temperatures is therefore expected increase under global warming. We investigated potential effects changes mast on wild boar population dynamics, a widespread abundant consumer species. Using long‐term monitoring data, we showed that acorn production enhances proportion breeding females. With body‐mass‐structured model fixed hunting rate...
Most mammalian populations suffer from natural or human-induced disturbances; are no longer at the equilibrium (i.e., stable [st]age distribution) and exhibit transient dynamics. From a literature survey, we studied patterns of dynamics for species spanning large range life-history tactics population growth rates. For each population, built an age-structured matrix calculated six metrics After controlling possible confounding effects phylogenetic relatedness among using principal component...
Summary 1. Harvest models are often built to explore the sustainability of dynamics exploited populations and help evaluate hunting management scenarios. Age‐structured commonly used for ungulate population dynamics. However, age hunted individuals is usually not recorded, data only include body weight sex limiting usefulness traditional models. 2. We propose a new modelling approach that fits collected by hunters develop rules when available. Using wild boar Sus scrofa as case study, we...
Abstract Climate influences the risk of disease transmission and spread through its direct effects on survival reproduction hosts pathogens. However, indirect climate variation, as those mediated by food resources host demography, are often neglected. Pulsed-resources produced oak trees in temperate forests constitute important for seed consumers strongly depend temperatures. Using an individual-based model, we provide a theoretical exploration influence warming dynamic African swine fever...
Density dependence plays an important role in population regulation the wild. It involves a decrease growth rate when size increases. Fifty years ago, Charlesworth introduced concept of 'critical age group', denoting classes which variation number individuals most strongly contributes to density regulation. Since this pioneering work, has rarely been used. In light Charlesworth's concept, we discuss need develop work between behavioural ecology, demography and evolutionary biology better...
Actuarial senescence is widespread in age-structured populations. In growing populations, the progressive decline of Hamiltonian forces selection with age leads to decreasing survival. As actuarial overcompensated by a high fertility, should be more intense species reproductive effort, theoretical prediction that has not been yet explicitly tested across species. Wild boar (Sus scrofa) females have an unusual life-history strategy among large mammals associating both early and effort...
Classical approaches for the analyses of density dependence assume that all individuals in a population equally respond and contribute to dependence. However, age-structured populations, different ages may differ their responses changes size how they affecting growth rate whole population. Here we apply concept critical age classes, i.e., specific scalar function describes one or combination several classes affect demographic rates negatively, order examine total acting on depends...
Abstract In marine and terrestrial ecosystems, organisms are affected by environmental variations that cause fluctuations in population size. The harvest–interaction hypothesis predicts environmentally induced size magnified harvesting. Empirical evidence is urgently needed the context of global change because greater will increase extinction risk. Here, we review theoretical empirical work has addressed fish, birds mammals. We identify mechanisms which harvesting might make more variable...
To maximize long-term average reproductive success, individuals can diversify the phenotypes of offspring produced within a event by displaying ‘coin-flipping’ tactic. Wild boar (Sus scrofa scrofa) females have been reported to adopt this However, whether magnitude developmental plasticity litter depends on stochasticity in food resources has not yet investigated. From monitoring, we found that juvenile similar-sized fetuses independent availability. By contrast, adult adjusted their...
