We describe methods for collecting corbicular pollen from honey bees as well as protocols for color sorting, acetolysis, and microscope slide preparation of pollen for taxonomic identification. In addition, we present pellet color and taxonomic diversity of corbicular pollen collected from five cropping systems using pollen traps.

Bacterial and archaeal cells exhibit remarkable diversity in shape and structure, critical in their adaptability and functionality. Among bacteria, the most commonly observed shapes include cocci and bacilli. Cocci are spherical and may exist singly or in groupings such as pairs (diplococci), chains (streptococci), clusters (staphylococci), or tetrads. Bacilli, in contrast, are rod-shaped and can also occur as single cells, in pairs, or chains, depending on their environmental and genetic...

2023
An improved method to measure pollen hydration profiles in Arabidopsis thaliana is described here. The new method offers higher resolution, is noninvasive, and is highly reproducible. The protocol represents a new tool for a finer dissection of the processes that regulate the early stages of pollination.

We present a non-lethal and automated mechanism to collect pollen from bumble bee (Bombus) workers returning to a hive. Instructions for producing, preparing, installing and using the devices are included. By using 3D-printed objects, modification to the design was timely, efficient and allowed for quick turnaround for testing.
FAQs
Sporopollenin forms much of pollen’s resistant outer wall, the exine, giving that layer structural durability. As the wall develops, its sculpturing and apertures become characteristic features rather than incidental surface details. These features matter biologically because the exine helps protect the grain, while apertures are associated with hydration and pollen-tube emergence during plant reproduction.
Apertures and surface sculpturing contribute different structural information about a pollen grain. Apertures influence how the grain hydrates and where the pollen tube emerges, whereas sculpturing creates surface patterns useful for distinguishing pollen types. Examining both features therefore connects reproductive function with the comparative identification of plant taxa.
Size, shape, surface architecture, and wall features provide complementary traits for comparing pollen grains. No single characteristic necessarily captures the full pattern of variation, so researchers evaluate these features together through comparative analysis. The resulting structural comparisons can support plant-taxon identification and contribute evidence for reconstructing evolutionary relationships.
A pollen morphology investigation uses microscopy to examine grain size, shape, surface architecture, apertures, and wall features. Researchers then compare the observed combination of traits among pollen samples or plant taxa. This workflow converts microscopic structure into evidence that can support identification, relationship studies, and interpretation of modern or fossil plant communities.
Comparative pollen evidence can help identify the plant taxa represented in a sample and clarify patterns of plant diversity. When the grains come from fossil material, their preserved structural features can also support interpretation of past plant communities. In modern samples, the same approach helps characterize the plant composition associated with present-day environments.
Pollen morphology supports several biological and interdisciplinary applications. In pollination studies, it provides structural information relevant to plant reproduction; in aerobiology and allergy research, it helps investigate airborne pollen. The same evidence can assist forensic and archaeological investigations when plant material must be examined, identified, or interpreted in context.
