This LTER Remote Sensing spatial raster dataset consists of Landsat Enhanced Thematic Mapper image data for Kellogg Biological Station LTER, on 2011-09-17 (16:11:12.1340940Z). Data were collected by Landsat 5, row 31, path 21. Cloud cover was 20.84 percent. These are reference data from the USGS EROS archive, not data generated by Kellogg Biological Station LTER. This product was created by the U.S. Geological Survey (USGS) and contains Landsat data files in Geographic Tagged Image-File Format (GeoTIFF).

Genetic barcoding of museum eggshell improves data integrity of avian biological collections
<p>Natural history collections are often plagued by missing or inaccurate metadata for collection items, particularly for specimens that are difficult to verify or rare. Avian eggshell in particular can be challenging to identify due to extensive morphological ambiguity among taxa. Species identifications can be improved using DNA extracted from museum eggshell; however, the suitability of current methods for use on small museum eggshell specimens has not been rigorously tested, hindering uptake. In this study, we compare three sampling methodologies to genetically identify 45 data-poor eggshell specimens, including a putatively extinct bird's egg. Using an optimised drilling technique to retrieve eggshell powder, we demonstrate that sufficient DNA for molecular identification can be obtained from even the tiniest eggshells without significant alteration to the specimen's appearance or integrity. This method proved superior to swabbing the external surface or sampling the interior; however, we also show that these methods can be viable alternatives. We then applied our drilling method to confirm that a purported clutch of Paradise Parrot eggs collected 40 years after the species' accepted extinction date were falsely identified, laying to rest a 53-year-old ornithological controversy. Thus, even the smallest museum eggshells can offer new insights into old questions.</p>

The Great British Liverwort Hunt – collecting wild accessions for molecular biology research while engaging the public
<p>During the lockdowns of the COVID-19 pandemic, outreach activities of universities were significantly perturbed. The Sainsbury Laboratory Cambridge University (SLCU) outreach project for the Cambridge festival in 2021 was therefore a fully online project, which asked people from across the mainland of the United Kingdom to send in plant samples of <i>Marchantia polymorpha</i>, and <i>Lunularia cruciata. </i>The samples were, upon arrival, established into axenic culture for use in research. Here, we deposit the names and locational data of the lines established in axenic culture for the wider use of the research community. Out of 76 samples received, 68 were successfully established in sterile tissue culture. This dataset also includes an analysis of the sex of the <i>M. polymorpha</i> accessions.</p>
