    The "Flora of Russia" project on iNaturalist brought together professional scientists and amateur naturalists from all over the country. Over 10,000 people were involved in the data collection. Within 20 months, the participants accumulated 750,143 photo observations of 6,857 species of the Russian flora. This constitutes the largest dataset of open spatial data on the country’s biodiversity and a leading source of data on the current state of the national flor

Received 5 March 1991 We have searched for direct leptoquark production in Z ° decays from a scan of the Z ° resonance, in the energy range 88.2 ~< x/] ~< 94.2 GeV, using 5.2 pb-~ of data. We exclude the existence of scalar leptoquarks with masses less than 41 to 44 GeV, depending on the charge assignments, at the 95% confidence level
