Data from: Quantifying demographic uncertainty: Bayesian methods for integral projection models (IPMs)

Bret D. Elderd & Tom E. X. Miller
Integral projection models (IPMs) are a powerful and popular approach to modeling population dynamics. Generalized linear models form the statistical backbone of an IPM. These models are typically fit using a frequentist approach. We suggest that hierarchical Bayesian statistical approaches offer important advantages over frequentist methods for building and interpreting IPMs, especially given the hierarchical nature of most demographic studies. Using a stochastic IPM for a desert cactus based on a 10-year study as a...

Data from: Habitat-mediated carry-over effects lead to context dependent outcomes of species interactions

Benjamin G. Van Allen & Volker H. W. Rudolf
1. When individuals disperse, their performance in newly colonized habitats can be influenced by the conditions they experienced in the past, leading to environmental carry-over effects. While carry-over effects are ubiquitous in animal and plant systems, their impact on species interactions and coexistence are largely ignored in traditional coexistence theory. 2. Here we used a combination of modelling and experiments with two competing species to examine when and how such environmental carry-over effects influence community...

Data from: Intraspecific trait variation and colonization sequence alter community assembly and disease epidemics

Christopher J. Dibble & Volker H. W. Rudolf
When individuals from multiple populations colonize a new habitat patch, intraspecific trait variation can make the arrival order of colonists an important factor for subsequent population and community dynamics. In particular, intraspecific priority effects (IPEs) allow early arrivers to limit the growth or establishment of later arrivers, even when competitively inferior on a per-capita basis. Through their effects on genes and traits, IPEs can alter short-term growth and long-term evolutionary change in single species metapopulations....

Data from: Parallelism in adaptive radiations of experimental Escherichia coli populations

Gerda Saxer & Michael Travisano
Adaptive radiations are major contributors to species diversity. While the underlying mechanisms of adaptive radiations, specialization and trade-offs, are relatively well understood, the tempo and repeatability of adaptive radiations remain elusive. Ecological specialization can occur through the expansion into novel niches or through partitioning of an existing niche. To test how the mode of resource specialization affects the tempo and repeatability of adaptive radiations, we selected replicate bacterial populations in environments that promoted the evolution...

Data from: Fungal symbionts maintain a rare plant population but demographic advantage drives the dominance of a common host

Yan-Yi Anny Chung, Thomas E. X. Miller, Jennifer A. Rudgers & Tom E. X. Miller
1. A potential driver of species abundance that remains understudied is the interaction between host species and their microbial symbionts. Beneficial symbionts could promote the dominance of common host species by increasing their population growth rates more than they do for rare species, and symbiont benefits could be important for maintaining rare species in communities. Alternatively, intrinsic differences in demography, independent of interactions with symbionts, could be the main driver of species’ relative abundances. 2....
