Methods in Ecology and Evolution, EarlyView.Abstract Ecologists are adapting structural causal modelling for spatial, phylogenetic and time‐series analysis. However, ecological extensions of path analysis and structural equation models (SEM) typically assume that interactions among variables are stationary, linear and additive, while ecological and evolutionary dynamics are often nonstationary ...

Methods in Ecology and Evolution, EarlyView.Abstract Structured population models are parameterized to accurately project expected population sizes, stage/state distributions and population growth rates, but they also predict the variation in outcomes among individuals, such as the variance and skewness of lifetime reproductive output (LRO) and lifespan, the probability of never reproducing, and

On Shape Preserving Smoothing Splines
In many approximation problems it is important that solutions preserve some shape properties such as positivity, monotonicity and/or convexity. The additional shape preserving conditions are usually considered as the positivity/negativity constraints on ...

Quantifying permeability of linear barriers to animal movement: The permeability R package
Methods in Ecology and Evolution, EarlyView.Abstract Animals have always navigated environments characterized by linear features that influence movement, whether rivers, ridges or ravines. Large‐scale changes in land use have led to increasing interactions with anthropogenic features, especially roads and fences.

Field‐level crop choice responses to weather‐induced yield shocks in the US Corn Belt
American Journal of Agricultural Economics, EarlyView.Abstract As climate change increases the frequency and severity of extreme heat events, farmers are expected to face greater variability in crop yields. Using 10 million field‐level observations, this study examines how farmers in the US Corn Belt adjust corn–soybean rotation decisions in response to yield shocks largely driven by weather fluctuations.

Allergy, EarlyView.Young children (0–9 years) and residents of urban areas appeared particularly vulnerable to respiratory allergy development and exacerbation. Incidence showed nonlinear associations with PM10, PM2.5, temperature, and alder/birch pollen, while DPMR showed similar patterns, except for NO2 and the interaction O3*NO2.
