Sample size requirements to evaluate policies in addiction research using interrupted time series analysis (ITS): Tools and guidance

Addiction, Volume 121, Issue 3, Page 695-712, March 2026.
Abstract Formal power calculations are rarely presented in interrupted time‐series (ITS) studies due to their technical complexity, creating a significant gap in methodological rigor. This paper aimed to make power and sample size determination more accessible for researchers, particularly in the field of addiction, by providing a suite of practical ...

Flowering Asynchrony and Temporal Mate Restriction in Tropical Peat Swamp Forest Trees

Biotropica, Volume 58, Issue 2, March 2026.
Tropical peat swamp forest trees flower asynchronously, restricting mating opportunities between conspecifics. Using an 18‐year dataset from Central Kalimantan, Indonesia, we show that while the same individual trees tend to flower together through time, there is enough turnover in which trees flower contemporaneously that lifetime mate restriction and

Alternative Future Vegetation Pathways Reveal Potential Transformations of Western US Ecosystems

Global Change Biology, Volume 32, Issue 3, March 2026.
We used climate‐analog impact models (AIMs) to project changes in vegetation across the western United States under a mid‐21st century climate scenario, characterize ecological transformation vulnerability based on projection divergence, and demonstrate how AIMs can inform decision‐making.

Spatial Autocorrelation of Species Diversity and Distributions in Time and Across Spatial Scales

Global Ecology and Biogeography, Volume 35, Issue 3, March 2026.
ABSTRACT Aim Spatial autocorrelation (SAC), also known as aggregation or clumping, reflects species niche and dispersal, has conservation significance, and affects ecological models. Yet, we know little about the spatial and temporal patterns of SAC in empirical data.

Poisson count time series

Journal of Time Series Analysis, Volume 47, Issue 2, Page 279-303, March 2026.
This article reviews and compares popular methods, some old and some recent, that produce time series having Poisson marginal distributions. The article begins by narrating ways where time series with Poisson marginal distributions can be produced.

A Mixture Transition Distribution Modeling for Higher‐Order Circular Markov Processes

Journal of Time Series Analysis, Volume 47, Issue 2, Page 304-320, March 2026.
ABSTRACT This study considers the stationary higher‐order Markov process for circular data by employing the mixture transition distribution modeling. The underlying circular transition distribution is based on Wehrly and Johnson's bivariate joint circular models.
