FACTORS AFFECTING CANNIBALISM AMONG NEWLY HATCHED WOLF SPIDERS (LYCOSIDAE, PARDOSA AMENTATA)

摘要: Abstract Cannibalism is a common phenomenon among young wolf spiders (Lycosidae). The purpose of this study was to investigate how various factors influence cannibalistic tendencies in hatchlings Pardosa amentata (Clerk 1757). basic experimental approach place pairs unfed similar body mass small containers without prey and measure if when cannibalism happened. From the data, we identified three different strategies. One large group never cannibalized thus died from starvation. Another shortly before time at which they were predicted die In these spiders, there strong positive relationship between average contestants their latency cannibalize. A third quickly cannibalize independent mass. We also tested higher unrelated than siblings, but...
