Bits of bamboo – Botanics Stories. In the Herbarium at RBGE, we store a huge number of sheets of archival quality paper with squashed and dried plant specimens stuck to them.
These have been collected over a period of hundreds of years, by plant collectors all around the world. It’s a phenomenal store of biodiversity, providing evidence of where different kinds of plants have been growing at different periods, and also allowing us access to genetic information from different times and places. Checking through the bamboo collections at RBGE’s Herbarium with Dr Linda Neaves There IS a trade-off involved in getting that genetic material, as our DNA extraction methods involve destructive sampling: the process includes a step where the plant tissue is pulverised then soaked in warm buffers, then discarded.

Herbarium specimens provide snapshots of plants’ past, data for future – #FloridaMuseumScience. While some might press flowers into books to preserve their beauty, researcher Mark Whitten does it to preserve history.
Whitten, a botanist in the Florida Museum of Natural History Herbarium, glues pressed plants onto archival paper and stores them as specimens in the museum’s collection. He said herbarium specimens show data about plants’ location, habitat, flowers and fruits at the time of their collection. With this information, researchers are starting to make connections about recent climate change and its influence on the seasonal cycles of plants, or plant phenology. Whitten said researchers lack good observational records on when plants start to flower, produce fruit or form leaves, which is where herbarium specimens come in. This specimen was prepared by Florida botanist Robert K.
“If you get enough samples, statistically you’re going to be able to get a pretty good window on the flowering period of a plant,” he said. Assessing the Relevance of Herbarium Collections as Tools for Conservation Biology. Adhikari, D., S.
K. Barik & K. Upadhaya. 2012. African genomes illuminate the early history and transition to selfing in Arabidopsis thaliana. Author Affiliations Edited by Johanna Schmitt, University of California Davis, CA, and approved April 11, 2017 (received for review October 13, 2016) Significance The principal plant model species, Arabidopsis thaliana, is central to our understanding of how molecular variants lead to phenotypic change.
In this genome-sequencing effort focused on accessions from Africa, we show that African populations represent the most ancient lineages and provide new clues about the origin of selfing and the species itself. Untitled. Are herbarium mosses reliable indicators of historical nitrogen deposition? Medicinal plant uses and names from the herbarium of Francesc Bolòs (1773–1844) Ethnopharmacological relevance Ethnobotany takes into account past uses to be projected into the present and future.
Most current ethnobotanical research is focused, especially in industrialised countries, on obtaining information of plant uses from elderly people. Historical ethnobotany is less cultivated, although papers have demonstrated its interest. Particularly poor, but potentially very relevant, is the attention paid to historical herbaria as a source of data on useful plants. Building on building mosses, a return to Schistidium in the built environment – Botanics Stories. Some Schistidium collections from the RBGE Herbarium Monday 27th March was the start of a month-long visit to RBGE by the Fraunhofer Institute for Building Physics‘s Dr Wolfgang Hofbauer, funded by the EU Synthesys Access programme.
This funding enables researchers from other institutes to get their hands on the natural history collections that they need to see and understand, but it is equally vital for collections-based institutes like ourselves, as it promotes the use and curation of some of the material that we conserve. Biodiversity Knowledge Integration Center. New life for 19th-century plants. Humans have long had a knack for concentrating heavy metals that would otherwise remain at low concentrations within the environment.
These human-produced pollutants can be found going back as far as one million years ago with fires in caves during the Paleolithic Era, to industrial development in the 19th century, to increased concentrations of contaminants like cadmium and lead in the 20th century. Yudina Ways Preserv Biolog. Extraction of ultrashort DNA molecules from herbarium specimens. Abstract DNA extracted from herbarium specimens is highly fragmented; therefore, it is crucial to use extraction protocols that retrieve short DNA molecules.
Insights into grass phenology from herbarium specimens - Primack - 2017 - New Phytologist. In this issue of New Phytologist, Munson & Long (pp. 1945–1955) publish a study that is notable for its innovative methods, focusing on an understudied but vital aspect of grasslands, and insightful results.
Their analysis of herbarium specimens sheds new light on how the reproductive timing of grasses responds to temperature and precipitation. Specifically, they find that warmer annual temperatures tend to accelerate reproductive times of C3 grasses, but delay reproductive times of C4 grasses, with the greatest effects seen in annual species and in wetter, more northern locations; and that increased precipitation tends to delay reproduction for most grass species. These findings suggest substantial, and potentially predictable, ecological consequences, and highlight the need for more work in this area. Munson & Long took an innovative approach to addressing this challenge. Mobilising Richard Spruce’s 19th century Amazon legacy.
