“…The primary floras and identification guides used were Krammer andLange-Bertalot (1986-2004) and Hartley et al (1996). All nomenclature was adjusted to that used by Whitton et al (1998), which follows conventions in Round et al (1990) and Fourtanier and Kociolek (1999). All taxa were identified to the highest resolution possible (usually species or variety).…”

“…Since then, more than 64,000 diatom species have been described-and new species are added to that list almost daily with the number of extant species extrapolated to ca 100,000. 4,5 The identification of diatoms (from the Greek 'diatomos' or 'cut in half') commonly relies on the highly differentiated cell wall (or frustule) that is mostly composed of silica (SiO 2 ).

Terrestrial diatoms as tracers in catchment hydrology: a review

et al. 2017

Diatoms are remarkable organisms. They are present in almost all habitats containing water (e.g., lakes, streams, soils, bark) and rank among the most common algal groups in both freshwaters and marine ecosystems. The ubiquitous character of aquatic diatoms has triggered countless applications as environmental tracers for studies in water quality, paleoclimate reconstruction and sediment tracing. However, diatoms also occur in the terrestrial environment. It is this plethora of diatom life-forms that has recently triggered interest in their use as tracers of hydrological processes. The use of diatoms in catchment hydrology has been very limited. Part of the reason is that until recently, the taxonomy and ecology of terrestrial diatom assemblages were largely unknown. However, in the past decade, much work has been done to quantify terrestrial diatom reservoir size, dynamics, and potential depletion following precipitation events. Therefore, such terrestrial diatoms now hold promise for use in catchment hydrology-for tracing runoff flow sources and pathways across a wide range of spatial scales. Here we review the literature on terrestrial diatoms and describe the various sampling protocols that have been designed and tested for specific applications in hydrological processes research. We review and summarize the work on terrestrial diatom reservoir characterization, transport mechanisms and pathways to show how such diatom-based tracer work might be possible at the catchment scale for rainfall-runoff studies. Finally, we present a vision for future work that might take advantage of terrestrial diatoms in catchment hydrology and discuss the main challenges going forward. © 2017 The Authors.

They count among the most common algal groups in both freshwaters and marine ecosystems. 1 Despite their microscopic size (10-200 microns), 2 diatoms generate an impressive amount of carbon through photosynthesis: almost as much as all rainforests combined. 3 Identification of diatoms date back to the early 1700s as noted by Round et al. 1 Decades later, Otto Friedrich Müller published the first description of a diatom in 1783 (Vibrio paxillifer ≡ Bacillaria paradoxa).

“…Given that the number of diatom species is estimated to be between 10 000 and 100 000 (Hasle & Syvertsen 1996) or approximately 200 000 (Mann & Droop 1996;Mann 1999), and that the number of diatom genera described is over 1000 (Fourtanier & Kociolek 1999), diatoms are the most divergent organisms among algae. Although the diversity of diatoms has been studied mainly based on valve morphology, the results of our study support the view expressed elsewhere (e.g.…”

SUMMARYIn the past 10 years Nitzschia sigmoidea (Nitzsch) W. Sm. has begun to occur in Japanese rivers in various areas. It is a common diatom in Europe but was previously absent in Japan. Each chloroplast of N. sigmoidea contains many unusual linear-oblong structures. The internal structure of the chloroplast in this species was observed using epifluorescence and electron microscopy with immunolocalization techniques. The linear-oblong structures in the chloroplasts could hardly be observed by conventional light microscopy of living cells, but were obvious in cells stained with propionocarmine. Transmission electron microscopy showed that the cross sections of this structure were lanceolate to fusiform with penetration by a single thylakoid. In cells stained with DAPI, chloroplast DNA was detected along both sides of the linear-oblong structures, and DNA fibrils were detected by electron microscopy. Immunofluorescence microscopy of sectioned cells and also immunoelectron microscopy revealed specific localization of Rubisco between these DNA-containing areas, which divided at the same time as the chloroplast. Our observations confirmed that the linear-oblong structures are pyrenoids. The diversity of localization patterns of chloroplast DNA in diatoms is discussed.
