Historic fish samples from the Southeast USA lack microplastics

Differential saturation of Pacific Northwest and Southeast (USA) fish assemblages

Plots of local versus regional richness have been used to test whether assemblages are ‘saturated’ with species. However, the validity of these tests is limited by scale-dependence and arbitrarily defined sampling units, statistical autocorrelation between local and regional richness data, and the confounding effects of propagule pressure. In this study, local versus regional richness plots wer...

Assessing the impact of exposure to microplastics in fish

Historic barley seed samples and their utility

Gene banks around the world hold over 370.000 accessions of barley (van Hintum and Menting, 2003). Although a large number of landraces and obsolete cultivars are stored in genebanks the geographic coverage of this conserved material is far from evenly distributed. For example only a handful of landraces from Northern Europe have been conserved (Jones et al, 2008a). Thus studies of geographic d...

Anthropocene streams and base-level controls from historic dams in the unglaciated mid-Atlantic region, USA.

Recently, widespread valley-bottom damming for water power was identified as a primary control on valley sedimentation in the mid-Atlantic US during the late seventeenth to early twentieth century. The timing of damming coincided with that of accelerated upland erosion during post-European settlement land-use change. In this paper, we examine the impact of local drops in base level on incision ...

Detection Trend of Helminth Eggs in the Strata Soil Samples from Ancient Historic Places of Korea

For several years, we have conducted a series of studies on the patterns of ancient parasitism prevailing in the soil of rural and urban areas of past Kingdom of Korea. Actually, during our survey of paleoparasitology in archaeological sites of Korean peninsula, numerous ancient parasite eggs were discovered in the samples from the city districts of Hansung (Joseon) and Buyeo (Baikje), the pala...
