(Ultra)high‐Pressure Metamorphism in Sedimentary Versus Basaltic Rocks: Insights From a Variscan Mélange in the South Carpathians

Journal of Metamorphic Geology, EarlyView.
ABSTRACT Reconstructing the pressure–temperature–time (P–T–t) evolution of (ultra)high‐pressure rocks is essential for constraining subduction and collisional dynamics. Subduction zones are often investigated using basic eclogites, whereas nonbasic high‐pressure rocks remain comparatively understudied, potentially hindering a comprehensive ...

Computed tomography reveals the endocranial anatomy of Crocodylia: Implications for phylogenetic relationships and ecomorphological convergence across Crocodylomorpha

Journal of Anatomy, EarlyView.
The evaluation of the endocranial anatomy of 43 crocodylian species reveals several differences, including variation in the curvature of the encephalic endocast, the size of the endosseous labyrinth and paratympanic sinuses, and the presence of additional snout sinuses.

A description of dental microanatomy and implantation geometry in Chamaeleonidae

Journal of Anatomy, EarlyView.
A reassessment of the dental histology in adult chamaeleons reveals the presence of periodontal ligament. Alongside alveolar bone and cementum, these tissues together constitute a compacted and remodelled tripartite periodontium. Our findings include the novel observation of plicidentine‐like protuberances of dentine within underlying bone.

Molecular phylogenetic analysis sheds light on the diversity and evolutionary history of the Neotropical and African Triplophyllum (Tectariaceae)

Journal of Systematics and Evolution, EarlyView.
We used a molecular approach to resolve the evolutionary lineages of Neotropical Triplophyllum, uncovering that current species circumscriptions are hindered by high morphological homoplasy in indument characters. Our results support the recognition of three new species and provide a necessary neotypification for T.

Education and the Shadow Economy: A Panel Cointegration Analysis

Kyklos, EarlyView.
ABSTRACT This study examines the impact of education on the shadow economy across 132 countries over the period 1991–2020. To this end, panel cointegration and panel error‐correction models are employed. The results of the panel cointegration tests indicate a stable long‐term relationship among the selected variables.

How Institutions Shape the Effects of Agricultural Cooperatives on Their Members

Kyklos, EarlyView.
ABSTRACT Agricultural cooperatives represent a promising way of improving the quality of life of half a billion smallholders, who account for the vast majority of the world's food production. Yet, little is known about the institutional factors that explain the potential benefits of being a member of a cooperative.

Divergent trajectories of genome architecture and chromosome evolution in ferns and angiosperms

New Phytologist, EarlyView.
Variation in key fern genomic traits across families, mapped onto a summary phylogenetic tree. Summary Ferns and angiosperms represent the two largest vascular plant lineages but exhibit striking genomic and ecological contrasts. We investigated whether differences in genome size, chromosome architecture, GC content, and stomatal traits reveal ...

Macroeconomic Effects of Public Investment in EMDEs: Nonlinear Effects of the Business Cycle, Fiscal Space, Capital Stock and Efficiency

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT The paper examines the macroeconomic effects of public investment in emerging market and developing economies (EMDEs). To this end the analysis develops a new measure of public investment shocks based on cyclically adjusted government investment.

Threshold Regression for Fixed‐T$$ T $$ Panel Data with Interactive Fixed Effects

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This paper develops a new toolbox for estimation and inference in panel data threshold regression models with interactive fixed effects and a fixed number of time periods, T$$ T $$. The toolbox is designed to be simple, accurate, and computationally efficient.
