Pattern and Duration of Copulation in Wolf Spiders (araneae, Lycosidae)
The temporal patterns of insertion of male palps, expansion of the hematodocha and duration of copulation are reported for 10 species of Schizocosa Chamberlin 1904, three species of Rabidosa Roewer 1955, one species of Gladicosa Brady 1986, one species of Hogna Simon 1885, two species of Isohogna Roewer 1960, one species of Trochosa C.L. Koch 1848, one species of Geolycosa Montgomery 1904, two ...
متن کاملEcology of Two Burrowing Wolf Spiders (Araneae: Lycosidae) Syntopic in Florida Scrub: Burrow/Body Size Relationships and Habitat Preferences
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...
متن کاملThe influence of sensory information on patch residence time in wolf spiders (Araneae: Lycosidae)
Foraging models emphasize reward and/or prey capture rates as primary determinants of residence time. The influence of sensory information has rarely been examined experimentally, but may also be important in animal foraging decisions. This study examined the influence of sensory cues without food reward on residence time in wolf spiders, as well as the interaction of visual and vibratory infor...
متن کاملBurrowing 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...
متن کاملThe relationship between offspring size and performance in the wolf spider Hogna helluo (Araneae: Lycosidae)
Life-history theory predicts a trade-off between number of offspring and investment (size) per offspring. An important component of this trade-off is how offspring size influences performance and survival. In this study, we examined the relationships between maternal size, offspring size and clutch size, as well as the relationship between offspring size and performance, in the wolf spider, Hog...
