Amblypygid-fungal interactions: The whip spider exoskeleton as a substrate for fungal growth.

Fungi and arthropods represent some of the most diverse organisms on our planet, yet the ecological relationships between them remain largely unknown. In animals, fungal growth on body surfaces is often hazardous and is known to cause mortality. In contrast, here we report the presence of an apparently non-harmful mycobiome on the cuticle of whip spiders (Arachnida: Amblypygi).

Globally distributed occurrences utilised in 200 spider species conservation profiles (Arachnida, Araneae).

Background: Data on 200 species of spiders were collected to assess the global threat status of the group worldwide. To supplement existing digital occurrence records from GBIF, a dataset of new occurrence records was compiled for all species using published literature or online sources, from which geographic coordinates were extracted or interpreted from locality description data.

New Information: A total of 5,104 occurrence records were obtained, of which 2,378 were from literature or online sources other than GBIF.

Species conservation profiles of a random sample of world spiders IV: Scytodidae to Zoropsidae.

Background: The IUCN Red List of Threatened Species is the most widely used information source on the extinction risk of species. One of the uses of the Red List is to evaluate and monitor the state of biodiversity and a possible approach for this purpose is the Red List Index (RLI). For many taxa, mainly hyperdiverse groups, it is not possible within available resources to assess all known species.
