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

Microscopy 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.

Native Perennial Vegetation Buffer Strips Improve Structural Indicators of Riparian Protection in Mediterranean Agroecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Riparian zones in Mediterranean agroecosystems are highly vulnerable to degradation because cultivation often reaches stream edges and annual vegetation senesces during the late‐summer dry period, leaving soils exposed when the first erosive autumn rains occur.

Seagrass species diversity in Tanzania based on morphological and molecular data

Nordic Journal of Botany, EarlyView.
Seagrass diversity along the Tanzanian coast has been documented mainly through morphology, with limited molecular reference data available for Tanzania and the wider Western Indian Ocean. This study combined morphological identification with nuclear ribosomal internal transcribed spacer (ITS) and plastid ribulose‐1,5‐bisphosphate carboxylase/oxygenase

Taxonomic revision of the genus Tzveleviochloa (Poaceae, Aveninae) in India

Nordic Journal of Botany, EarlyView.
The taxonomy of Tzveleviochloa in India is revised based on morphological evidence, comprehensive observations of herbarium specimens and field records, and several botanical explorations in the study area. The accepted diversity is increased from two to five species, including two recently described species. The genus is distributed in the Western and
