This article investigates the transformation of the official historical narrative of the Golden Horde in Kazakhstan, tracing a significant shift from Nazarbayev to Tokayev’s presidencies. The narrative of the Golden Horde became a strategic component of the second president, Tokayev, who announced the commemoration of 750 years of the Horde foundation in Kazakhstan and proclaimed that it laid the foundations for Kazakh statehood. The research explores the abrupt transformation of the official historical narrative and underscores the pivotal role of historians as memory actors. The study investigates the “memory game” between two schools of historians in independent Kazakhstan, revealing the agency of a new generation of historians in reshaping the national historical narrative through historicizing strategies, thus engaging in memory politics. This contribution extends the literature on the mnemonic context in Kazakhstan and non-state memory actors in authoritarian settings, shedding light on the dynamics of historical representation and memory politics in evolving mnemonic landscapes.

Environmental DNA (eDNA) metabarcoding has lagged in parasite biodiversity assessments. We implemented this method to examine parasite diversity in sediment and water from 4 physically connected aquatic habitats in coastal South Carolina, USA, as part of a ParasiteBlitz in April 2023. Sediment was collected using a syringe corer, and water was sampled using active filtration and passive collection. Five amplicon libraries, using primers targeting portions of the mitochondrial COI of platyhelminths and 18S ribosomal RNA genes of nematodes, myxozoans, microsporidians, and protists, successfully yielded parasite sequences. Out of >5.8 million sequences, we identified >1,000 parasite amplicon sequence variants (ASVs) corresponding to ~600 parasite operational taxonomic units, from 6 parasite groups. Most diversity was observed among the microsporidians, whose assay demonstrated the highest fidelity. Actively-filtered water samples captured ASVs of all 6 groups, whereas sediment captured only 4, despite yielding 3× as many ASVs. Low DNA yields from passive water samples resulted in fewer, but some unique, ASVs representing 3 parasite groups. The most efficient sampling method varied with respect to parasite group across habitats, and the parasite communities from each habitat were distinct regardless of sampling method. We detected ASVs of 9 named species, 4 of which may represent introductions to the US. The abundance of our results demonstrates the effectiveness and efficiency of eDNA metabarcoding for assessing parasite diversity during short, intensive surveys, and highlights the critical need for more comprehensive sequence databases and the development of primers for those parasite taxa that elude detection using eDNA methods.
