Evolutionary mobility and genetic dynamics of MORFFO genes: shuttling among ancient plant lineages

New Phytologist, Volume 250, Issue 2, Page 1248-1264, April 2026.
Summary Plastid genomes (plastomes) of land plants are characterized by their architectural and genic content stability. However, fern plastomes exhibit unexpected dynamism, characterized by the presence of mobile protein‐coding genes (CDS) – Mobile Open Reading Frames in Fern Organelles (MORFFOs). We investigate the evolutionary dynamics of MORFFOs in

The Dynamics of Coordination and Actor Movements in Advocacy Coalitions: A Theoretical Longitudinal Perspective Within the ACF

Politics &Policy, Volume 54, Issue 1, February 2026.
ABSTRACT This theoretical article examines the dynamics of stability and change in public policy coalitions using the Advocacy Coalition Framework as a foundation. We focus on how intra‐coalition and inter‐coalition coordination serves as a causal factor influencing the stability of coalition composition and the mobility of actors over time, especially

Volatile Energy, Stunted Investment: How Energy Price Inflation Shapes Foreign Direct Investment Into Africa

World Affairs, Volume 189, Issue 1, Spring 2026.
ABSTRACT In the study, we investigate the roles energy price inflation and its volatility play in shaping foreign direct investment (FDI) inflow into Sub‐Saharan Africa (SSA). Applying data from 37 SSA economies between 2002 and 2023 and the system generalized method of moments (GMM) as the estimation strategy to account for endogeneity, the results ...

CMiNet: An R package and user‐friendly Shiny App for constructing consensus microbiome networks

Methods in Ecology and Evolution, Volume 17, Issue 1, Page 52-66, January 2026.
Abstract Microbial networks offer critical insights into community structure, ecological interactions and host–microbe dynamics. However, constructing reliable microbiome networks remains challenging due to variability among existing inference methods, limited overlap between inferred networks and the absence of a gold standard (a universally accepted ...
