... Typical specimens of new plants are added to the Herbarium owing to continuing work of scientists of Moscow State University in the field of plant systematics. For example, 60 new vascular plant species were described by botanists of the University over the period of 2012-2016 (Ukrainskaja et al., 2013;Pimenov and Klyuikov, 2014;Seregin et al., 2015;Sukhorukov and Kushunina, 2015a, 2015bSukhorukov et al., 2015Vislobokov, 2015;Duyfjes et al., 2016;Koçyiğit et al., 2016;Lyskov et al., 2016;Pimenov et al., 2016;Sukhorukov and Nilova, 2016;Yurtseva et al., 2016aYurtseva et al., , 2016b. The collection was used as a basic source for several important molecular revisions of some groups of plants (Degtjareva et al., 2013;Seregin et al., 2015;Kramina et al., 2016;Yurtseva et al., 2016b). ...
In 2015–2016, 785887 specimens were scanned at the Herbarium of Moscow State University (MW), which comprised 77.7% of the total collection. The metadata of the digital herbarium include the identifier (ID) of each specimen, its species name, and geographical reference (area code). As the largest in Russia database with respect to biodiversity, the Herbarium includes 712925 images of specimens of vascular plants and 72962 specimens of bryophytes. The digital herbarium is interrelated with the Catalogue of Life international database and has enriched it with 160 new species. Images of 781882 specimens have been put online as JPG files (the resolution is 300 dpi) on the web portal of the National Depository Bank of Live Systems (https://plant.depo.msu.ru/). The portal is open for all Russian biological collections.
В 2015-2016 гг. в Гербарии МГУ (MW) было отсканировано 785 887 образцов, или 77.7% общего объема коллекции. Отмечено, что метаданные Цифрового гербария МГУ включают для каждого образца уникальный идентификатор, номенклатуру и привязку к географическим районам. Установлено, что крупнейшая в России база данных по биоразнообразию состоит из изображений 712 925 образцов сосудистых растений и 72 962 образцов мхов. Цифровой гербарий интегрирован с международной базой данных Catalogue of Life, что позволило дополнить ее 160 неучтенными названиями. В Интернете опубликованы изображения 781 882 образцов в формате JPG (разрешение 300 dpi) на портале Национального банка-депозитария живых систем (https://plant.depo.msu.ru/). Эта площадка открыта для любых биологических коллекций России.
The Moscow University Herbarium (MW) added a millionth specimen to the collections in June 2016.
Today, there are 1 011 253 specimens in MW collections (61th place in the world’s ranking) representing
37 100 species and subspecies of vascular plants and 2223 species and subspecies of bryophytes. An average
annual growth of the collection in 2005—2016 was 15 100 specimens, with exceptional 22 013 specimens
added to the herbarium in 2016. Since 2005, major accessions have originated from Eastern Europe,
Siberia and Russian Far East, the Caucasus, and South Asia (vascular plants); Taimyr, Russian Far East,
and North Caucasus (bryophytes). The Moscow University Herbarium has gained budget for the digitisation
of collections within the Program of the National Depository Bank of Live Systems, and ca. 786 000
specimens (77.7 %) were scanned since May 2015. Ca. 502 000 records are published already on our
web-portal (http://plant.depo.msu.ru/, https://plant.mitotech.ru/), including JPG images and metadata required
for indexing. A brief review of publications based on a study of MW collections in 2005—2016 is
given.
