Abstract Current thinking in life‐history theory and the biology of ageing suggests that rates, consequently life spans, evolve largely as a function trade‐offs with reproduction. While various evolutionary constraints are generally acknowledged to exist, their potential role determining rates is rarely considered. This review integrates three types information assess relative importance shaping rates: (a) empirical work on presence intraspecific trade‐offs; (b) theoretical factors limiting...
Climate change is projected to increase the frequency and intensity of extreme heat events, may humidity levels, leading coupled thermal hydric stress. However, how modulates impacts stress on species their interactions currently unknown. Using an insect host-parasitoid interaction: Indian meal moth,
Density regulation of the population growth rate occurs through negative feedbacks on underlying vital rates, in response to increasing size. Here, we examine a capital breeder how rates different life-history stages, their elasticities and are affected by changes We developed an integrated model for local Svalbard barnacle geese, Branta leucopsis, using counts, reproductive data individual-based mark-recapture (1990-2017) age class-specific survival, reproduction number individuals.

Abstract An increasing number of empirical studies aim to quantify individual variation in demographic parameters because these patterns are key for evolutionary and ecological processes. Advanced approaches estimate heterogeneity now using a multivariate normal distribution with correlated random effects account the latent correlations among different occurring within individuals. Despite frequent use mixed models, we lack an assessment their reliability when applied Bernoulli variables....
It is increasingly recognized that incorporating life history trade-offs into evolutionary demography models requires to be decomposed fixed (a.k.a genetic) and individual dynamic) components. This fundamental in order understand how are related dynamic components of heterogeneities generate variance trajectories. Therefore, embedding such population projection matrices usually three categories: a life-history determining trait (e.g., age or stage), the genetic trade-off, modeling component....
Abstract The familial structure of a population and the relatedness its individuals are determined by demography. There is, however, no general method to infer kinship directly from life cycle structured population. Yet, this question is central fields such as ecology, evolution conservation, especially in contexts where there strong interdependence between dynamics. Here, we give formula compute, any matrix model, expected number arbitrary kin (sisters, nieces, cousins, etc) focal...
1. Climate change is projected to increase the likelihood of extreme heat events, but it may also alter humidity levels, leading potential for coupled thermal and hydric stress. While increasing frequency intensity events have been well-documented their negative effects on species interactions, how modulates impacts waves currently unknown. 2. We investigated interacted with different timings durations affect life histories in an insect host-parasitoid interaction, comprising Indian meal...
ABSTRACT Commonly used two‐sex discrete‐time population projection models rely on mating functions developed for continuous‐time frameworks that overestimate the number of unions between reproductive individuals. This has important consequences our understanding evolution and demography populations consequently management conservation. Here, we propose a novel function is robust by obeying all properties necessary to be ecologically valid flexible accommodating systems efficiency in...

Abstract The persistence of wildlife populations is under threat as a consequence human activities, which are degrading natural ecosystems. Commercial forestry the greatest to biodiversity in boreal forests. Forestry practices have degraded most available habitat, threatening populations. Understanding population responses is, therefore, critical for their conservation. Population viability analyses effective tools predict management. However, quantifying mechanisms driving complex dynamics...
Climate impacts are not always easily discerned in wild populations as detecting climate change signals is challenged by stochastic noise associated with natural variability, variability biotic and abiotic processes, observation error demographic rates. Detection of the impact on requires making a formal distinction between population long-term trends from those generated noise. The time emergence (ToE) identifies when signal anthropogenic can be quantitatively distinguished variability....

Abstract Structured population projection models are fundamental to many fields of science. They enable abundance forecasting for populations categorized by various traits such as age (for demography), patch spatial ecology), genotype genetics), infectious stage epidemiology) or capital (economics). The demography a structured population, determined the transition rates (e.g., survival, fertility) between its states, also shapes relatedness – kinship structure. This structure (a...
