Climate stability drives multidimensional nestedness of amphibian assemblages in a Chinese sky island system

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

Mammalian herbivory indirectly shapes savanna arthropod communities but only at very low or high levels

Journal of Animal Ecology, EarlyView.
This study investigates how large mammalian herbivores shape arthropod communities in African savannas, using a broad gradient of herbivory types and intensities to assess these effects under real‐world, non‐experimental conditions. Abstract Savanna ecosystems support unique biodiversity and provide livelihoods for millions of people.

Adoption of Minimum Tillage and Mid‐Season Drainage in Rice Production and Their Impacts on Farm and Economic Performance

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT This paper investigates the effects of two greenhouse gas (GHG) mitigation practices—minimum tillage and mid‐season drainage—on rice farmers' farm performance (e.g., crop yield and risk) and economic outcomes (e.g., income and vulnerability).

Estimating Causal Effects With Observational Data: Guidelines for Agricultural and Applied Economists

Journal of Agricultural Economics, EarlyView.
ABSTRACT Most research questions in agricultural and applied economics are causal in nature: they study how changes in one or more variables (such as policies, prices or weather) affect one or more other variables (e.g., income, crop yields or pollution).

Understanding cooperative membership and maize market participation in Rwanda: A Bayesian triple‐hurdle analysis

Annals of Public and Cooperative Economics, EarlyView.
Abstract Smallholder market participation studies often focus narrowly on selling decisions, overlooking the institutional role of agricultural cooperatives, particularly in contexts like Rwanda, where cooperatives underpin agricultural policy. Consequently, empirical evidence on how cooperative membership shapes farmers’ commercialization across ...

Assessing novelty, feasibility and value of creative ideas with an unsupervised approach using GPT‐4

British Journal of Psychology, EarlyView.
Abstract Creativity is defined by three key factors: novelty, feasibility and value. While many creativity tests focus primarily on novelty, they often neglect feasibility and value, thereby limiting their reflection of real‐world creativity. In this study, we employ GPT‐4, a large language model, to assess these three dimensions in a Japanese‐language
