Summary: Pollen allergy is a significant concern, and this study provides a reference pollen guide for future research by studying the morphological characteristics of airborne pollen. The findings show that the shape, size, aperture type, and exine pattern of pollen are related to the classification of plant groups. Most of the airborne pollen are small in size and have distinct exine patterns. This study contributes to a better understanding of airborne pollen biodiversity.

Summary: The study evaluated the utility of an integrative approach to analyze mixed-pollen samples from agricultural sites in Canada. The findings suggest that pollen metabarcoding is a more suitable method for characterizing the composition of mixed pollen samples compared to traditional melissopalynology. Additionally, adopting a multi-locus approach that integrates information from multiple markers can improve the quantitative application of this method.

Summary: The possibility of identifying plants based on the taxonomic information from their pollen grains has various applications in biology. In the past, pollen origin was analyzed using microscopy and chemical treatment, which is time-consuming and requires expert knowledge. Now, DNA analysis provides advantages and challenges compared to traditional methods. This article presents a practical guide for genetic pollen analysis using nanopore sequencing, with a focus on pollen collected by pollinating insects.

Summary: This study aimed to investigate the pollen morphology of melliferous plant taxa in Southern Khyber Pakhtunkhwa-Pakistan, using light microscope (LM) and scanning electron microscope (SEM) to study 18 species. Variations in pollen morphology were observed, with most species having prolate-spheroidal pollen shape. The information provided in this study will be useful in identifying potential melliferous plants, determining geographical origin of honey, and ensuring availability of pure honey in local and international markets.

Summary: The visual classification of pollen grains is essential for various agricultural applications, particularly for preserving the biome and maintaining the quality of honey-based products. Artificial intelligence can automate the process, but there is still room for improvement in terms of processing time, memory size, and accuracy. A new method called APFA-Net, based on deep feature aggregation and channel-wise attention, outperforms existing state-of-the-art methods.

Summary: The dispersed miospore and pollen assemblages from the Krkonose-Piedmont Basin were described from different formations, showing a trend of increasing number of monolete miospores and pollen with stratigraphic age. The most typical genera and species in the assemblages were identified, along with comparisons with other Czech and European coalfields and basins.

Summary: Research conducted on DNA sequences of pollen from historical specimens of the rusty patched bumble bee showed that there were no temporal changes in the bee's forage, suggesting that the decline of the species was likely not driven by limitations of specific floral species in terms of space or time.

Summary: Pollen plays an important role in various scientific areas, and there have been attempts to automate its identification and classification using computer vision. However, as of now, manual analysis by experts is still the main approach. This study analyzes and compares state-of-the-art research on pollen detection and classification, explores issues such as data accessibility and machine learning methods, and identifies crucial areas for further research.

Summary: Pollen traits are important for understanding the evolutionary history of angiosperms. In this study, the pollen morphology of the vataireoid clade was analyzed, revealing a wide range of variations and independent evolution events. The results suggest that pollen evolution in this clade has been relatively labile and exhibited little phylogenetic conservatism.

Summary: This study investigated the contribution of ornamental nursery plants to honey bee pollen sources. The results showed that plant genera grown in nurseries, such as Rosa, Rhus, and Ilex, contributed significantly to pollen volume during weeks 23-27 of the year. Among the genera not grown in nurseries, Toxicodendron was also important during weeks 23 and 24, and Trifolium was important throughout the season.

Summary: This study focused on the taxonomic utilization of palynological metaphors for selected members of the family Poaceae. It found that pollen shape, polar and equatorial diameter, pore size, P/E ratio, and pore sculpturing are of good taxonomic value and play a significant role in the identification and delimitation of Poaceae taxa.

Summary: This study utilizes anatomical analysis of fossils from Vancouver Island, Canada, to support the development of a whole plant concept for the Eocene species of Gleichenia and provide data for the first organismal concept of an extinct species of Gleichenia from the Cenozoic fossil record. The findings suggest that the characteristics of the Gleicheniaceae family were present during the Cretaceous and Paleogene periods, with modern species well-established and diversifying.

Summary: This study presents a palaeoecological reinvestigation from the Kardashynskyi mire in southern Ukraine, reconstructing the vegetation dynamics, fire history, and land use for the past 8300 years. The results show that both climate and human activities have driven the vegetation changes, and the remaining special vegetation types are severely threatened under current conditions.

Summary: The relationships between woody vegetation cover and fire, climate, herbivory, and human activities in African savanna ecosystems are complex. Fire suppression policies implemented in a national park in northeast Namibia from 1888 to 2005 did not lead to noticeable decreases in fire or enhanced tree recruitment, suggesting that fire occurrence in savanna ecosystems is more closely linked to climate than management. Fire management should adapt to rainfall variability and integrate customs of early dry season burning.

Summary: This paper revises the genus Aberlemnia from the Early Devonian of Scotland based on its type-material A. caledonica and describes a new species, Aberlemnia krizii sp. nov, from the Silurian of Czechia. The study provides detailed diagnoses and highlights the differences between the two species. Aberlemnia is positioned on an evolutionary clade line leading to the Lycophytina.
