Abstract Sporomorphs (pollen and spores) are a mainstay of research into past vegetation, increasingly sporomorph chemistry is being used as palaeoecological tool. To make extant sporomorphs directly comparable to fossil specimens, fresh material processed remove labile compounds isolate the sporopollenin wall. A range processing approaches currently in use, but chemistries produced by these different techniques have not yet been compared across taxa. It therefore clear how they compare terms efficiently isolating without changing its chemical structure, what impact on relative similarities differences among taxa (i.e. whether more closely related species will always appear chemically similar, regardless processed). Here, we test this applying five from 15 vascular plant phylogeny. We show that each approach has own idiosyncrasies impacts chemistry. For most part common pattern among‐taxon variability uncovered, phylogenetic signal within supported. Working with spectral derivatives generally increases agreement approaches, decreases strength signal. No one ideal, choice which use likely depend goal study, type quantity processed, laboratory facilities available for processing.

Studying pollen and spores preserved in sedimentary archives has emerged as a pivotal method for reconstructing past environments understanding the long-term dynamics of Earth’s ecosystems. This study explores utility proxies palaeoenvironmental conditions, highlighting methodological advancements their extraction analysis that have enhanced our ability to interpret historical climate vegetation patterns. We can infer wide range ecological climatic parameters through detailed sediment analysis, from shifts communities biodiversity changes hydrological cycles fire regimes. These innovations provide more comprehensive ecosystem responses anthropogenic changes. also discusses implications these findings modern environmental management, including applications change adaptation, conservation, restoration sustainable land use planning. By integrating insights into contemporary management practices, we better predict mitigate impacts current future changes, ensuring resilient
