Instability of Sandy Soil on the Lake Wales Ridge Affects Burrowing by Wolf Spiders (araneae: Lycosidae) and Antlions (neuroptera: Myrmeleontidae)

چکیده
Pruebas con la araña Geolycosa demuestran que esta especie puede ser excluídas del ecosistema de “Southern Ridge Sandhill-turkey oak” en la loma de Lake Wales, dado que sus madrigueras se derrumban rápidamente en el suelo natural inestable (arena “Astatula”). Resultados semejantes fueron obtenidos en pruebas de hoyos excavados por larvas de la hormiga león (Myrmeleontidae), lo cual podría ser utilizado como un bio-indicador de la estabilidad del suelo.

Burrowing Wolf Spiders, Geolycosa spp. (Araneae: Lycosidae): Gap Specialists in Fire-Maintained Florida Scrub
Florida Scrub is a hotspot of biological diversity containing many endemic species such as burrowing wolf spiders (Geolycosa species), that are threatened by habitat destruction. This study investigated why two spicies, G. xera archiboldi (McCrone) and G. hubbelli Wallace, are significantly underrepresented in fire-maintained scrubby flatwoods, a widespread scrub habitat on the Lake Wales Ridge...

This fourteen year long study in the Florida scrub on the Lake Wales Ridge demonstrated that visually searching for open burrows of Geolycosa spiders was an effective method for sampling populations in the winter dry season, except one year when abnormally high precipitation during an El Niño event caused many spiders to close their burrows. Not only could the two endemic Geolycosa species be i...

The monotypic genus Nukuhiva Berland, 1935 with N. adamsoni (Berland, 1933) as type species, is re-described and transferred from the Pisauridae Simon, 1890 (fishing or nursery-web spiders) to the Lycosidae Sundevall, 1833 (wolf spiders) based on genitalic and somatic characters. Nukuhiva adamsoni, originally described from French Polynesia, appears to inhabit mountainous habitats of volcanic o...
