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 کاملNukuhiva Berland, 1935 is a troglobitic wolf spider (Araneae: Lycosidae), not a nursery-web spider (Pisauridae).
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...
متن کاملDiet influences mate choice selectivity in adult female wolf spiders
Most studies of female choice have assumed that mating preferences are shared within a population or species. However, variation both within and among females exists in natural populations, and foraging history is among the many ways in which females may vary. Here, we used diet manipulations in an effort to understand how foraging history influences female mate choice. Immature Schizocosa wolf...
متن کاملNo evidence for a relationship between hemolymph ecdysteroid levels and female reproductive behavior in <i>Schizocosa</i> wolf spiders
This study used radioimmunoassay (RIA) to explore the relationship between levels of hemolymph ecdysteroids and female reproductive behavior in Schizocosa wolf spiders. Specifically, we investigated the relationship between circulating ecdysteroid concentrations in females and 1) likelihood to copulate, or female receptivity [Experiment I— Schizocosa avida (Walckenaer 1837)], 2) time post copul...
متن کاملsynthesis of sulfides from alcohols and thiols in solvent-freeconditions and deoxygenation of sulfoxides
کاتالیست یک سنتز جدید برای تیواترها توصیف شده است. واکنش الکل ها با آریل، هتروآریل و آلکیل تیو ل ها درحضور 1،3،5- تری آزو- 2،4،6- تری فسفرین-2،2،4،4،6،6 هگزاکلراید ((tapc به عنوان یک کاتالیست موُثر، بازده های خوب تا عالی از تیواترها را حاصل می کند. علاوه براین، واکنش تحت شرایط بدون فلز و بدون حلال پیش می رود، بنابراین یک مکمل جالب برای روش های شناخته شده سنتز تیواترها ارائه می دهد. یک مکانیسم ا...
