Made in the shade: Leaf responses of native wildflowers to single‐axis photovoltaic solar energy

PLANTS, PEOPLE, PLANET, EarlyView.
As solar energy expands globally, balancing renewable power generation with biodiversity and ecosystem health has become an urgent challenge. This study investigated how native wildflowers respond at leaf level to the unique microclimates created by rotating solar panels in California's Central Valley.

Harvesting of two alpine Artemisia: Effects of an amateur practice on wild plant dynamics

PLANTS, PEOPLE, PLANET, EarlyView.
Wild plants are consumed all over the world, and knowledge of the effects of harvesting is necessary to ensure the sustainability of this activity. Our 3‐year study of two closely related alpine Artemisia species in the Southern Alps revealed a positive impact of harvesting at the plant scale and on the short term.

MortalitySmooth: An R Package for Smoothing Poisson Counts with P-Splines

Journal of Statistical Software, 2012
The MortalitySmooth package provides a framework for smoothing count data in both one- and two-dimensional settings. Although general in its purposes, the package is specifically tailored to demographers, actuaries, epidemiologists, and geneticists who ...

Accelerating the prioritisation of plant species with underexplored medicinal potential: The pm4mp (Phylogenetic Methods for Medicinal Plants) R package

PLANTS, PEOPLE, PLANET, EarlyView.
Medicinal plants used in ethnobotanical traditions to treat or prevent diseases have gained renewed interest for their largely untapped potential in drug discovery. In this study, we developed and tested novel methods to prioritise plant species based on their unexplored medicinal potential. By enabling researchers to target the most promising species,

The zero inflated negative binomial – Crack distribution: some properties and parameter estimation [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2015
The zero inflated negative binomial-Crack (ZINB-CR) distribution is a mixture of Bernoulli distribution and negative binomial-Crack (NB-CR) distribution, which is an alternative distribution for the excessive zero counts and overdispersion.

According to whom? Spousal, household, and plot differences in improved cassava variety adoption in Nigeria

PLANTS, PEOPLE, PLANET, EarlyView.
Agricultural innovations underpin most investments that aim to increase agricultural productivity globally. Improved crop varieties have historically constituted the bulwark of agricultural innovation outputs and are credited with the success of large‐scale interventions such as the Green Revolution. Much research has shown, however, that gender shapes

A Comparison of the Robust Zero-Inflated and Hurdle Models with an Application to Maternal Mortality

Mathematical and Computational Applications
This study evaluates the performance of count regression models in the presence of zero inflation, outliers, and overdispersion using both simulated and real-world maternal mortality dataset.

Exploring eco‐evolutionary and temporal patterns of arbuscular mycorrhizal fungal communities colonizing Sorghum bicolor across sites of contrasting land use history and climate

PLANTS, PEOPLE, PLANET, EarlyView.
Sorghum bicolor is a globally important cereal crop with annual yields exceeding 50 million tons across more than 100 countries and can be grown on marginal lands where conventional agriculture is limited. We examined how eight genetically diverse sorghum genotypes shaped arbuscular mycorrhizal fungal (AMF) community assembly across two contrasting ...

An Alternative Estimator for Poisson–Inverse-Gaussian Regression: The Modified Kibria–Lukman Estimator

Algorithms
Poisson regression is used to model count response variables. The method has a strict assumption that the mean and variance of the response variable are equal, while, in practice, the case of overdispersion is common.
