Predation on a pygmy shrew, Sorex minutus, by the noble false widow spider, Steatoda nobilis
Ecosphere, Volume 14, Issue 2, February 2023., 2023 Abstract The noble false widow spider Steatoda nobilis is a globally invasive species with implications for public health and possibly for native ecosystems. Here, we report on a case of predation on a protected species of vertebrate, a pygmy shrew Sorex minutus in Britain. The importance and novelty of this report are: (1) this is the third documented

Invasive brown widow spiders disperse aerially under a broad range of environmental conditions
Ethology, Volume 128, Issue 8, Page 564-571, August 2022., 2022 We tested dispersal by spiderlings of the invasive brown widow (Latrodectus geometricus) under field conditions in the Negev Desert of Israel. Invasive brown widow spiderlings ballooned more during the day than at night and under a wide range of environmental conditions.
