Description

  • arrow_drop_downarrow_drop_upCollecting details

    Collection 11987 was collected by M.L. Beker on 13th August 2007 in Endalen, SVALBARD (78.1937°N, 15.7891°E, altitude approximately 30 m above sea level - Google maps). The ectomycorrhizal family Rosaceae (genus Dryas) was present.

    The surrounding habitat was described as arctic tundra pastureland with a substrate of soil, corresponding to the IUCN habitat We map from the collector's description of the habitat to the International Union for Conservation of Nature (IUCN)'s definition using a standardised set of rules. Please see this page for a full list of IUCN habitats. 4.1: Grassland – Tundra.

    According to the GPS data the collection was in the Russian Arctic desert WWF ecoregion The World Wildlife Fund (WWF) have divided the world into 867 terrestrial ecoregions. The ecoregion here is estimated by mapping from the GPS coordinates of the collection using data made available by Dinerstein et al (2017).

Compare this collection to its species

This section compares data for this collection against its true species and also against the most likely species as determined by our identifier. More often than not these will be the same species, but where this is not the case, the data may be used to help explain why the identifier got it wrong.
