Sampling design and estimates of observation error greatly reduce quasi-extinction probability in plant populations Open
Estimates of population dynamics and risk of extinction are sensitive to both mean rates of annual change and also the variation in these rates caused by environmental stochasticity. The analytical machinery to incorporate the latter into …

Dynamic and context-dependent keystone species effects in kelp forests Open
Sea otters are an iconic keystone predator that can maintain kelp forests by preying on grazing invertebrates such as sea urchins. However, the effects of sea otters on kelp forests vary over their geographic range. Here, we analyze two 30…

Density, Climate, and Stochasticity Shape Four Centuries of Population Dynamics for Two Long‐Lived Tree Species Open
The dynamics of colonizing populations may be strongly influenced by both extrinsic (e.g., climate and competition) and intrinsic (e.g., density) forces as well as demographic and environmental stochasticity. Understanding the impacts of t…

Rare events, ecological dynamics, and the importance of long-term demographic studies Open
While multiple reasons make long-term demographic studies disproportionally valuable, much of their importance comes from the ability to detect and quantify rare events. We argue here that rare events can be critical for understanding impo…

Nonlinear life table response experiment analysis: Decomposing nonlinear and nonadditive population growth responses to changes in environmental drivers Open
Life table response experiments (LTREs) decompose differences in population growth rate between environments into separate contributions from each underlying demographic rate. However, most LTRE analyses make the unrealistic assumption tha…

Demographic responses of hybridizing cinquefoils to changing climate in the Colorado Rocky Mountains Open
Hybridization between taxa generates new pools of genetic variation that can lead to different environmental responses and demographic trajectories over time than seen in parental lineages. The potential for hybrids to have novel environme…

Geographic and taxonomic variation in adaptive capacity among mountain-dwelling small mammals: Implications for conservation status and actions Open
Contemporary climate change is modifying the distribution, morphology, phenology, physiology, evolution, and interspecific interactions of species. Effects of climate change are mediated not only through the magnitude of change experienced…

Understanding extinction risk and resilience in an extremely small population facing climate and ecosystem change Open
San Nicolas Island (SNI) foxes historically had the highest densities of the six subspecies of Channel Island fox, four of which were listed as endangered in the 1990s. As an island species, SNI foxes are inherently vulnerable because they…

Climate warming threatens the persistence of a community of disturbance‐adapted native annual plants Open
With ongoing climate change, populations are expected to exhibit shifts in demographic performance that will alter where a species can persist. This presents unique challenges for managing plant populations and may require ongoing interven…

Resource availability and heterogeneity shape the self‐organisation of regular spatial patterning Open
Explaining large‐scale ordered patterns and their effects on ecosystem functioning is a fundamental and controversial challenge in ecology. Here, we coupled empirical and theoretical approaches to explore how competition and spatial hetero…

Testing Demographic Methods Using Field Studies of Five Dissimilar Species Open
We analyzed how the choice of different modeling frameworks influences the results of demographic analyses, with the goal of assessing how robust population predictions are to different methods and assumptions. Our simulation tests use dat…

A critical comparison of integral projection and matrix projection models for demographic analysis Open
Structured demographic models are among the most common and useful tools in population biology. However, the introduction of integral projection models (IPMs) has caused a profound shift in the way many demographic models are conceptualize…

Climate and synchrony with conspecifics determine the effects of flowering phenology on reproductive success in <i>Silene acaulis</i> Open
Changes in flowering phenology resulting from climate change could impact individual plant fitness and population viability. Flowering phenology can mediate plant reproductive success in several ways, including pollinator interactions, flo…
View article: Latitudinal gradients in population growth do not reflect demographic responses to climate
Latitudinal gradients in population growth do not reflect demographic responses to climate Open
Spatial gradients in population growth, such as across latitudinal or elevational gradients, are often assumed to primarily be driven by variation in climate, and are frequently used to infer species’ responses to climate change. Here, we …

Breeding transients in capture–recapture modeling and their consequences for local population dynamics Open
Standard procedures for capture–mark–recapture modelling (CMR) for the study of animal demography include running goodness-of-fit tests on a general starting model. A frequent reason for poor model fit is heterogeneity in local survival am…

Climate manipulations differentially affect plant population dynamics within versus beyond northern range limits Open
Predicting species' range shifts under future climate is a central goal of conservation ecology. Studying populations within and beyond multiple species' current ranges can help identify whether demographic responses to climate change exhi…

Contrasting selection at multiple life stages maintains divergent adaptation between sunflower ecotypes Open
Conspecific populations living in adjacent, but contrasting, microenvironments represent excellent systems for studying natural selection. These systems are valuable because gene flow maintains genetic homogeneity except at loci experienci…

Dynamic shifts in social network structure and composition within a breeding hybrid population Open
Mating behaviour and the timing of reproduction can inhibit genetic exchange between closely related species; however, these reproductive barriers are challenging to measure within natural populations. Social network analysis provides prom…

Incorporating intraspecific variation into species distribution models improves distribution predictions, but cannot predict species traits for a wide‐spread plant species Open
The most common approach to predicting how species ranges and ecological functions will shift with climate change is to construct correlative species distribution models (SDMs). These models use a species’ climatic distribution to determin…
