Pollen Morphology of Crucianella L. (Rubiaceae) Based on Light and Scanning Electron Microscope Data and Implications for Taxonomy

open access: yesMicroscopy Research and Technique, EarlyView.
This study provides the palynological analysis of 12 Crucianella L. taxa using LM and SEM. Variations in pollen size, aperture number, and exine ornamentation were identified as key traits, demonstrating their taxonomic value for distinguishing closely related species and subspecies within the genus. ABSTRACT Crucianella L.

From Empire to Aid: Analysing Persistence of Colonial Legacies in Foreign Aid to Africa

open access: yesJournal of International Development, EarlyView.
ABSTRACT For decades now, Western development agencies and donors have been castigated for their colonial biases in providing aid to Africa. It is well established that donors provide considerably more foreign aid to their former colonies relative to other countries.

African Economic Growth Revisited

open access: yesJournal of International Development, EarlyView.
ABSTRACT This paper presents an updated analysis of the patterns of economic development in Africa over the last 60 years. The analysis stresses the heterogeneity of development trajectories among sub‐Saharan African (SSA) countries. We examine the joint dynamics of income and population in 35 SSA countries.

The Impacts of Southwest Indian Ocean Tropical Cyclones on Transient Weather in Réunion

open access: yesInternational Journal of Climatology, EarlyView.
Tropical cyclones which make passage near Réunion can have significant impacts on transient weather relative to long‐term means on the island. In this paper, these impacts were determined by a topological analysis of non‐landfalling tropical cyclones. The relationship between storm intensity, distance, duration, and seasonality plays an equal role in ...

Bias Correction of ERA5 Temperature Across Five Topoclimatic Clusters: A Comparative Evaluation of Four Methods

open access: yesInternational Journal of Climatology, EarlyView.
ERA5 near‐surface temperature over South America exhibits systematic cold biases in daily maximum temperature and warm biases in daily minimum temperature. To address the continent's strong climatic and topographic heterogeneity, South America was partitioned into five topoclimatic clusters, and four bias‐correction approaches were evaluated. The Multi‐

Surface and Tropospheric Climatic Trends in the Galápagos Archipelago Based on the Galápagos Archipelago Refined Analysis Dataset

open access: yesInternational Journal of Climatology, EarlyView.
The Galápagos Archipelago's near‐surface climate is primarily influenced by interannual El Niño‐Southern Oscillation variability, with no statistical evidence for long‐term trends in air temperature, humidity, or precipitation. While tropospheric warming and increased atmospheric stability are observed, these trends are largely decoupled from near ...

Frequent, Intense and Prolonged Human‐Perceived Heat Waves Over the Arabian Peninsula in Recent Decades

open access: yesInternational Journal of Climatology, EarlyView.
The spatial distribution of WBGT exhibits a widespread and significant warming trend across the Arabian Peninsula (AP), with, particularly, strong increases observed over the central and northern inland and eastern coastal regions of Saudi Arabia, Kuwait and Qatar, where trends exceed ~0.25°C decade−1.
