This study summarises the status of microplastic research in marine and freshwater specimens in natural museum collections around the world. Abundances, distributions, and types of microplastics in the archived collections are discussed. Museum collections can fill knowledge gaps on evolution of microplastic pollution before and during the Plasticene era. The specimens in these studies, ranging from plankton to vertebrates, were collected and archived between 1900 and 2019, and are dominated by specimens from marine ecosystems. All the specimens included in this review were preserved by freezing or in ethanol/formaldehyde except for specimens in one study that were preserved via cryomilling. Microfibers were the most common microplastics in the reviewed studies. We recommend more microplastic studies over a wider taxonomic range of species and across a longer span of years utilizing archival specimen collections around the world in order to establish reference points and develop temporal trends for microplastic pollution of the environment.

Learning about the actors associated with the development of collections helps trace the signs of coloniality in museum discourse. The case of João dos Santos Pereira Jardim, the main donor of a collection in the ethnography section of the Municipal Museum of Figueira da Foz, confirms that military campaigns in colonial territories were key to enriching the collections of Portuguese museums. By reconstructing the journey of this military officer and the significance of two objects he collected, we reveal how this type of actor contributed to the growth of collections and prevailing Eurocentric narratives in museums.

The collections of the Instituto de Investigação Científica Tropical were integrated into the Universidade de Lisboa in 2015, leaving the Museu Nacional de História Natural e da Ciência responsible for their management, preservation and access. This historical and scientific heritage includes archives, libraries, natural history, archaeological and ethnographic collections, scientific instruments and the Jardim Botânico Tropical. Most of the collections were created as part of colonial scientific missions promoted by the Portuguese government during the nineteenth and twentieth centuries.

Understanding the diversity of microscopic hyphomycetes is an ongoing effort, and many species remain undescribed. While studying lichen organismal composition in western Canada, metagenomic data revealed the presence of an unknown species of (, Ascomycota), a genus of pollen-parasitic fungus with no previous records in the region. We developed genus-specific primers to amplify DNA in lichen and adjacent substrate extractions, successfully detecting multiple lineages of across a wide geographic range within North America.

During the Late Bronze Age (ca. 11th-8th century BCE), far-reaching and extensive trade and exchange networks linked communities across Europe. The area around Seddin in north-western Brandenburg, Germany, has long been considered as at the core of one such networks.

Background And Aims: Hornworts are rarely found in the fossil record, so each new find provides important insights regarding their evolution and diversity. Here we revisit a controversial genus, Notothylacites, described from the Late Cretaceous of Central Europe, which has liverwort morphology, but bears hornwort spores.
Methods: The fossil material was originally studied in 1970 by Pacltová using pollen preparation techniques.
